BACKGROUND Multiple sclerosis ( MS ) is a major cause of chronic , neurological disability , with a significant long-term disability burden , often requiring comprehensive rehabilitation . OBJECTIVES To systematic ally evaluate evidence from published Cochrane Review s of clinical trials to summarise the evidence regarding the effectiveness and safety of rehabilitation interventions for people with MS ( pwMS ) , to improve patient outcomes , and to highlight current gaps in knowledge . METHODS We search ed the Cochrane Data base of Systematic Review s up to December 2017 , to identify Cochrane Review s that assessed the effectiveness of organised rehabilitation interventions for pwMS . Two review ers independently assessed the quality of included review s , using the Revised Assessment of Multiple Systematic Review s ( R-AMSTAR ) tool , and the quality of the evidence for reported outcomes , using the GRADE framework . MAIN RESULTS Overall , we included 15 review s published in the Cochrane Library , comprising 164 r and omised controlled trials ( RCTs ) and four controlled clinical trials , with a total of 10,396 participants . The included review s evaluated a wide range of rehabilitation interventions , including : physical activity and exercise therapy , hyperbaric oxygen therapy ( HBOT ) , whole-body vibration , occupational therapy , cognitive and psychological interventions , nutritional and dietary supplements , vocational rehabilitation , information provision , telerehabilitation , and interventions for the management of spasticity . We assessed all review s to be of high to moderate method ological quality , based on R-AMSTAR criteria .Moderate- quality evidence suggested that physical therapeutic modalities ( exercise and physical activities ) improved functional outcomes ( mobility , muscular strength ) , reduced impairment ( fatigue ) , and improved participation ( quality of life ) . Moderate- quality evidence suggested that inpatient or outpatient multidisciplinary rehabilitation programmes led to longer-term gains at the levels of activity and participation , and interventions that provided information improved patient knowledge . Low-qualitty evidence suggested that neuropsychological interventions , symptom-management programmes ( spasticity ) , whole body vibration , and telerehabilitation improved some patient outcomes . Evidence for other rehabilitation modalities was inconclusive , due to lack of robust studies . AUTHORS ' CONCLUSIONS The evidence suggests that regular specialist evaluation and follow-up to assess the needs of patients with all types of MS for appropriate rehabilitation interventions may be of benefit , although the certainty of evidence varies across the different types of interventions evaluated by the review s. Structured , multidisciplinary rehabilitation programmes and physical therapy ( exercise or physical activities ) can improve functional outcomes ( mobility , muscle strength , aerobic capacity ) , and quality of life . Overall , the evidence for many rehabilitation interventions should be interpreted cautiously , as the majority of included review s did not include data from current studies . More studies , with appropriate design , which report the type and intensity of modalities and their cost-effectiveness are needed to address the current gaps in knowledge Introduction Large proportions of the population are not meeting recommended levels of physical activity and have increasingly sedentary lifestyles . Low levels of physical activity are predictive of poor health outcomes and time spent sedentary is related to a host of risk factors independently of physical activity levels . Building an evidence base of the best approaches to intervene in the lifestyles of inactive individuals is crucial in preventing long-term disease , disability and higher mortality rates . Methods and analysis Systematic search es will be conducted on all relevant data bases ( eg , PubMed , Scopus , CINAHL , PsycINFO ) . Studies will be included if they assess interventions aim ed at changing physical activity or sedentary behaviour levels in adults ( over 18 ) who are inactive and do not suffer from chronic conditions . Studies must also be r and omised controlled trials ( RCTs ) , have a primary outcome of physical activity or sedentary behaviour , and measure outcomes at least 6 months after intervention completion . Studies will be coded using the Behaviour Change Technique ( BCT ) taxonomy v1 and Template for Intervention Description and Replication ( TIDieR ) guidelines . 2 review ers will independently screen full-text articles and extract data on study characteristics , participants , BCTs , intervention features and outcome measures . Study quality will also be assessed independently by 2 review ers using the Cochrane risk of bias tool . A meta- analysis will be considered if there is sufficient homogeneity across outcomes . GRADE criteria will be used to assess quality of evidence . Dissemination This will be the first review to systematic ally appraise interventions aim ed at changing the physical activity or sedentary behaviour of inactive individuals using RCT design s with a 6-month follow-up post-intervention . This review will better inform intervention design ers targeting inactive population s and inform the design of a future complex intervention . Review registration number This protocol was registered with the International Prospect i ve Register of Systematic Review s ( PROSPERO ) on 17 October 2014 ( registration number : CRD42014014321 ) Purpose . To examine the relationship between vigorous physical activity and  dementia risk . Design . Prospect i ve study design utilizing physical activity data from the Health and Retirement Study and cognitive outcome data from the Aging , Demographics , and Memory Study . Setting . Community-based . Subjects . Adults age 71 and over ( N = 808 ) with 3 to 7 years of physical activity information prior to dementia/no dementia diagnosis . Measures .  Physical activity  was measured by  participation in vigorous activities such as aerobics , sports , running , bicycling , and heavy housework three or more times per week  ( yes/no ) . Dementia diagnosis was based on an expert panel ( e.g. , neuropsychologists , neurologists , geropsychiatrists ) who performed and review ed a battery of neuropsychological tests . Analysis . Binary logistic regression models were used to account for demographic characteristics , genetic risk factors ( one or two apolipoprotein E ε4 alleles ) , health behaviors ( e.g. , smoking , drinking alcohol ) , health indicators ( body mass index ) , and health conditions ( e.g. , diabetes , heart disease ) in a sequential model-building process . Results . The relationship between vigorous physical activity and dementia risk remained robust across models . In the final model , older adults who were physically active were 21 % ( p ≤ .05 ) less likely than their counterparts to be diagnosed with dementia . Conclusion . Vigorous physical activity may reduce the risk for dementia independently of the factors examined here . This study 's findings are important given that few preventative strategies for dementia have been explored beyond hormonal therapy and anti-inflammatory drugs Mobile devices are a promising channel for delivering just-in-time guidance and support for improving key daily health behaviors . Despite an explosion of mobile phone applications aim ed at physical activity and other health behaviors , few have been based on theoretically derived constructs and empirical evidence . Eighty adults ages 45 years and older who were insufficiently physically active , engaged in prolonged daily sitting , and were new to smartphone technology , participated in iterative design development and feasibility testing of three daily activity smartphone applications based on motivational frames drawn from behavioral science theory and evidence . An “ analytically ” framed custom application focused on personalized goal setting , self-monitoring , and active problem solving around barriers to behavior change . A “ socially ” framed custom application focused on social comparisons , norms , and support . An “ affectively ” framed custom application focused on operant conditioning principles of reinforcement scheduling and emotional transference to an avatar , whose movements and behaviors reflected the physical activity and sedentary levels of the user . To explore the applications ' initial efficacy in changing regular physical activity and leisure-time sitting , behavioral changes were assessed across eight weeks in 68 participants using the CHAMPS physical activity question naire and the Australian sedentary behavior question naire . User acceptability of and satisfaction with the applications was explored via a post-intervention user survey . The results indicated that the three applications were sufficiently robust to significantly improve regular moderate-to-vigorous intensity physical activity and decrease leisure-time sitting during the 8-week behavioral adoption period . Acceptability of the applications was confirmed in the post-intervention surveys for this sample of midlife and older adults new to smartphone technology . Preliminary data exploring sustained use of the applications across a longer time period yielded promising results . The results support further systematic investigation of the efficacy of the applications for changing these key health-promoting behaviors Review question / objective What are the effects of weight management interventions that include a diet component on weight‐related outcomes in pregnant and postpartum women ? The primary objective of this systematic review is to evaluate the effectiveness of weight management interventions which include a diet component and are aim ed at limiting gestational weight gain and postpartum weight retention in women . The second objective of this systematic review is to investigate included intervention components with respect to effect on weight‐related outcomes . This may include , but is not limited to : length of intervention , use of face‐to‐face counselling , group or individual consultations , use of other interventions components including exercise , use of goals and use of support tools like food diaries , coaching , including email or text message support . Background Around half of all women of reproductive age are either overweight or obese,1,2,3 with women aged 25‐34 years having a greater risk of substantial weight gain compared with men of all ages.1,4 Excessive gestational weight gain ( GWG ) and postpartum weight retention ( PPWR ) may play a significant role in long term obesity . Having one child doubles the five‐ and 10‐year obesity incidence for women , with many women who gain excessive weight during pregnancy remaining obese permanently.5 Excessive GWG and /or PPWR can also significantly contribute to short‐ and long‐term adverse health outcomes for mother , baby and future pregnancies.6,7 Maternal obesity increases the risk of pregnancy related complications such as pre‐eclampsia , gestational diabetes mellitus , stillbirth and the rate of caesarean section.8 Childhood obesity is a further long term complication of maternal obesity for offspring , which may persist in to adulthood.9 Excess GWG is also a risk factor for PPWR both in the short and long‐term.10,11 Nehring et al. conducted a meta‐ analysis with over 65,000 women showing that , compared to women who gained weight within recommendations during pregnancy , women with GWG above Institute of Medicine weight gain recommendations , 12 retained an additional 3.1 kg and 4.7 kg after three and greater than or equal to 15 years postpartum , respectively.13 The health risk associated with PPWR is highlighted in a study of 151,025 Swedish women followed between 1992 and 2001.The study identified the risk of adverse pregnancy outcomes for those who gained three or more units of Body Mass Index ( kg/m2 ) between consecutive pregnancies ( an average of two years ) was much higher compared with women whose BMI changed from ‐1.0 and 0.9 units.14 Long‐term chronic disease risk may also be affected by PPWR as weight retention at the end of the first year post‐partum has been found to be a predictor of maternal overweight 15 years later.15With around 14‐20 % of women retaining 5 kg or more 12 months postpartum,16,5 the risk of developing conditions like diabetes , metabolic syndrome and cardiovascular disease may be increased.17 It becomes evident that interventions which aim to support attainment of healthy weight both in the antenatal and postpartum periods are key health priorities for women during this life stage . Lifestyle factors of overweight , having poor diet quality , and not undertaking enough moderate‐to‐vigorous physical activity are amongst the top five predictors of mortality in women.18 Additionally it is noted that , for many women , pregnancy and the postpartum period are associated with a reduction in physical activity.19 It is known that a combination of poor dietary choices , an increase in sedentary time and reduction in physical activity are all contributors to the development of overweight and obesity . With this in mind , current research has focused on lifestyle interventions to limit GWG and PPWR . Thangaratinam et al. review ed 44 r and omized controlled trials ( 7278 women ) where interventions including diet , physical activity or both were evaluated for their influence on maternal weight during  pregnancy.20 Results indicate that all were significantly effective in reducing GWG compared with the control group . More specifically , dietary interventions were the most effective in reducing weight gain , with a mean weight loss of ‐3.84 kg compared with ‐0.72 kg and ‐1.06 kg for physical activity and the mixed ( diet plus physical activity ) approach , respectively.20 This finding is supported by Hill and colleagues ' recent systematic review of theory based interventions to limit GWG.21 Included studies in this review reported an underpinning theory base and were classified as adopting a dietary , physical activity or mixed approach . Hill et al. concluded that studies which included a diet intervention were significantly more effective at limiting GWG.21 In 2011 Tanentsapf et al. review ed the effect of dietary interventions alone for reducing GWG in normal weight , overweight and obese pregnant women.22 This review analysed 13 r and omized controlled trials and quasi‐r and omized controlled trials with a dietary intervention to prevent excessive GWG in women . The review concluded that dietary interventions during pregnancy were effective in reducing GWG with an effect of ‐1.92 kg ( n=1434 ) compared with the control group.22 Tanentsapf et al. identified that trials differed in the conduct of the interventions with various diet and non‐diet related components utilised . Dietary approaches were highly variable with some trials focusing only on calorie restriction and others included additional target macronutrient distribution for intake . Some trials further provided feedback based on maternal weight gain guidelines .12 Interventions also varied in delivery method with a variety of modes used , including face‐to‐face , individual or group consultations and /or written correspondence . The frequency of communication , despite the type or mix , also changed from trial to trial with additional methods via telephone , posted material s , feedback or food diaries utilised . The inclusion of physical activity in addition to diet intervention was also common . Whilst the recent review by Tanentsapf et al.22 identified that dietary interventions are effective in reducing GWG , the review did not investigate the impact that different intervention components , delivery methods or dietary counselling approaches had on gestational weight management . It remains unclear as to which intervention components optimize GWG in women . The impact of lifestyle interventions has also been investigated in the postpartum period . The recent systematic review from van der Pligt et al. reported seven of 11 studies review ed were successful in limiting PPWR.23 As with studies aim ed at limiting GWG , interventions included in van der Pligt et al. 's review differed greatly in their conduct . Six of these seven studies included both dietary and physical activity components for the intervention , with the final successful study including a diet only intervention . Five of the successful studies recruited overweight or obese women only . Intervention time varied considerably in successful studies with some running for as little at ten days , and others up to six months . Bertz et al. demonstrated that their 12‐week behavior modification intervention which targeted diet alone or diet and exercise , including two individual sessions with a dietitian and physical therapist , provision of scales for weight self‐monitoring and bi‐weekly text messages was successful in achieving significant weight loss following the intervention , and sustained at one year.24 The diet intervention and the diet and exercise intervention  yielded significant weight loss compared to the control . Following 12 weeks a reduction of ‐8.3 + /‐ 4.2 kg for diet intervention and ‐6.9 + /‐ 3.0 kg for diet and exercise was observed . Additionally after one year , the diet intervention showed ‐10.2 + /‐ 5.7 kg reduction and ‐7.3 + /‐ 6.3 kg for the diet and exercise intervention (p<0.001).24 Colleran et al. also found significant weight change results by implementing a 16‐week intervention which consisted of weekly individual sessions with a dietitian regarding calorie restriction , two additional home visits regarding exercise , weekly food diary completion and email support.25 The intervention group had greater weight loss compared to the control group ( ‐5.8 kg + /‐ 3.5 kg vs ‐1.6 kg + /‐ 5.4 kg ) . It can be seen that various methods have been utilized in investigating the impact of diet and physical activity interventions on PPWR . The review by van der Pligt et al.23 highlights the impact successful lifestyle interventions can have on postpartum weight change . However , this review did not investigate the different intervention strategies utilized . It remains unclear as to the optimal setting , delivery method , diet strategy , contact frequency or intervention length to limit PPWR . Previous systematic review s for both GWG and PPWR have focused on the effectiveness of lifestyle interventions as a whole for weight management in pregnant and postpartum women.20,23 And despite Tanentsapf et al. 's focus on dietary interventions for GWG,22 much is still unknown about the effectiveness of differing diet interventions over the antenatal and postpartum period . Specifically , the impact of differing diet intervention strategies on maternal weight gain is not known . Firstly , this systematic review will focus on whether  weight management interventions which include a dietary component  are effective in pregnant and postpartum women . In addition to this , this review will investigate the different intervention strategies utilized and their effectiveness in maternal weight management . A search of systematic review protocol data bases has shown that there is no current review underway for this topic BACKGROUND The present review systematic ally evaluates correlates of physical activity across the socio-ecological model for people with depression . SUBJECTS AND METHODS Two independent review ers search ed Embase , PubMed , and CINAHL from their inception until May 2015 , combining the medical subject heading ' depression ' or ' depressive ' with ' physical activity ' or ' exercise ' . Data were extracted by the same independent research ers and summarized according to the socio-ecological model . RESULTS Fifty-nine papers involving 101,539 persons with depression were eligible and enabled us to evaluate 42 correlates . Correlates that were consistently ( n ≥ 4 ) associated with lower physical activity participation in depressed persons were a higher level of depressive symptoms , a higher body mass index , the presence of physical co-morbidity and a lower self-efficacy . The role of social , environmental and policy factors on  physical activity participation is unknown and should be addressed in future research . CONCLUSION In persons with depression  physical activity participation  is a complex behavior that is influenced by many different factors . Significant correlates should be confirmed in prospect i ve studies . Interventions to improve modifiable physical and mental health variables in people with depression should be developed and evaluated Background The prevalence of overweight and obesity is high amongst healthcare professionals and there is growing interest in delivering weight loss interventions in the workplace . We conducted a systematic review to ( i ) examine the effectiveness of workplace-based diet and /or physical activity interventions aim ed at healthcare professionals and to ( ii ) identify and describe key components of effective interventions . Seven electronic data bases were systematic ally search ed . Results Thirteen r and omised controlled trials met the inclusion criteria , of which seven had data available for meta- analysis . Where meta- analysis was possible , studies were grouped according to length of follow-up ( < 12 months and ≥12 months ) and behavioural target ( diet only , physical activity only or diet and physical activity ) , with outcome data pooled using a weighted r and om effects model . Nine studies reported statistically significant ( between-group ) differences . Four studies reported being informed by a behaviour change theory . Meta- analysis of all trials reporting weight data demonstrated healthcare professionals allocated to dietary and physical activity interventions lost significantly more body weight ( −3.95 Kg , [ 95 % CI −4.96 to- 2.95 Kg ] ) than controls up to 12 months follow up . Conclusions Workplace diet and /or physical activity interventions targeting healthcare professionals are limited in number and are heterogeneous . To improve the evidence base , we recommend additional evaluations of theory-based interventions and adequate reporting of intervention content Over the years , physical activity and exercise have been used to positively impact the health and quality of life of persons infected with HIV and , more recently , has been associated with a spectrum of body composition changes . The aim of this review was to examine the effects of various exercise interventions on body composition in HIV positive adults , using a search strategy of r and omized , controlled trials ( RCTs ) . A systematic review was performed by five independent review ers using a predetermined protocol adapted from previous research for assessing the articles for inclusion , the extracted data , and method ological quality . Eight RCTs involving 430 ( 26 % female ) HIV positive adults performing exercise a minimum of thrice weekly for at least six weeks were finally selected : Four were progressive resistance training ( PRT ) studies , three were aerobic training ( AT ) studies , and one involved yoga . In the PRT studies , there were significant increases in three anthropometric measures , namely , body mass , sum of skinfolds and sum of limb girths . In the AT studies , significant decreases were found in seven anthropometric measures , namely , body mass index , waist-hip ratio , body mass , triceps skinfold , waist circumference and sum of skinfolds . With yoga , the changes were non-significant . Exercise contributes to improved body composition and , when applied safely , appears to be beneficial for adults living with HIV/AIDS . However , these findings should be interpreted cautiously due to the relatively few RCTs published to date . Future studies would benefit from increased attention to sample size , female participants , participant follow-up , complete statistical analysis and intention-to-treat analysis Abstract Background Little is known about which behavior change strategies motivate older adults to increase their physical activity . Purpose The purpose of this study was to assess the relative effects of two sets of behavior change strategies to motivate increased physical activity among older adults :  interpersonal and intrapersonal . Methods Community-dwelling older adults ( N = 102 , mean age = 79 ) were r and omized in a 2 × 2 factorial experiment to receive interpersonal ( e.g. , social support , friendly social comparison ; no , yes ) and /or intrapersonal ( e.g. , goal setting , barriers management ; no , yes ) behavior change strategies , combined with an evidence -based , physical activity protocol ( Otago exercise program ) and a physical activity monitor ( Fitbit One ™ ) . Results Based on monitor data , participants who received interpersonal strategies , compared to those who did not , increased their average minutes of total physical activity ( light , moderate , vigorous ) per week , immediately ( p = .006 ) and 6 months ( p = .048 ) post-intervention . Similar , increases were observed on measures of functional strength and balance , immediately ( p = .012 ) and 6 months ( p = .003 ) post-intervention . The intrapersonal strategies did not elicit a significant increase in physical activity or functional strength and balance . Conclusions Findings suggest a set of interpersonally oriented behavior change strategies combined with an evidence -based physical activity protocol can elicit modest , but statistically and clinical ly significant , increases in older adults ’ physical activity and functional strength and balance . Future research should replicate these findings and investigate the sustained quantity of physical activity elicited by these strategies and their impact on older adults ’ quality of life and falls . Trial Registration The Clinical Trials.gov registration identifier is NCT02433249 Background To counteract decline in physical performance and physical activity in older patients during hospitalization , multiple physical interventions were developed . However , it is unknown whether these are effective in this particular population . This systematic review aim ed to identify the effect of physical interventions on physical performance and physical activity in older patients during hospitalization . Methods The systematic search included PubMed , EMBASE , Cinahl , the Trials data base of The Cochrane Library and SPORTd iscus from inception to 22 November 2017 . Studies were included if the mean age of the patient cohort was 65 years and older and the effect of physical interventions on  physical performance or physical activity  was evaluated during hospitalization . Results Fifteen r and omized controlled trials met the inclusion criteria . Overall , the effect of physical interventions on physical performance was inconsistent . Patient tailored interventions , i.e. continuously adapted to the capabilities of the patient were not found to be superior over interventions that were not . Physical activity as outcome measure was not addressed . Reporting of intensity of the interventions and adherence were frequently lacking . Conclusions Evidence for the effect of physical interventions on physical performance in older patients during hospitalization was found uncertain . Further research on the efficacy of the intervention is needed , comparing types of intervention with detailed reporting of frequency , intensity and duration OBJECTIVE health-related quality of life ( HRQOL ) and mental well-being are associated with healthy ageing . Physical activity positively impacts both HRQOL and mental well-being .  Yoga is a physical activity that can be modified to suits the needs of older people and is growing in popularity . We conducted a systematic review with meta- analysis to determine the impact of yoga-based exercise on  HRQOL and mental well-being in people aged 60 + . METHODS search es were conducted for relevant trials in the following electronic data bases ; MEDLINE , EMBASE , Cochrane Central Register of Controlled Trials , CINAHL , Allied and Complementary Medicine Data base , PsycINFO and the Physiotherapy Evidence Data base ( PEDro ) from inception to January 2017 . Trials that evaluated the effect of physical yoga on HRQOL and /or on mental well-being  in people aged 60 + years were included . Data on HRQOL and mental well-being were extracted . St and ardised mean differences and 95 % confidence intervals ( CI ) were calculated using r and om effects models . Method ological quality of trials was assessed using the PEDro scale . RESULTS twelve trials of high method ological quality ( mean PEDro score 6.1 ) , totalling 752 participants , were identified and provided data for the meta- analysis . Yoga produced a medium effect on HRQOL ( Hedges ' g = 0.51 , 95 % CI 0.25 - 0.76 , 12 trials ) and a small effect on mental well-being ( Hedges ' g = 0.38 , 95 % CI 0.15 - 0.62 , 12 trials ) . CONCLUSION yoga interventions result ed in small to moderate improvements in both HRQOL and mental well-being in people aged 60 + years . Further , research is needed to determine the optimal dose of yoga to maximise health impact . PROSPERO REGISTRATION NUMBER ( CRD42016052458 ) Background Patients admitted to the intensive care unit with critical illness often experience significant physical impairments , which typically persist for many years following resolution of the original illness . Physical rehabilitation interventions that enhance restoration of physical function have been evaluated across the continuum of recovery following critical illness including within the intensive care unit , following discharge to the ward and beyond hospital discharge . Multiple systematic review s have been published appraising the exp and ing evidence investigating these physical rehabilitation interventions , although there appears to be variability in review methodology and quality . We aim to conduct an overview of existing systematic review s of physical rehabilitation interventions for adult intensive care patients across the continuum of recovery . Methods / design This protocol has been developed according to the Preferred Reporting Items for Systematic Review s and Meta-Analyses Protocol ( PRISMA -P ) guidelines . We will search the Cochrane Systematic Review Data base , Data base of Abstract s of Review s of Effectiveness , Cochrane Central Register of Controlled Trials , MEDLINE , Excerpta Medica Data base and Cumulative Index to Nursing and Allied Health Literature data bases . We will include systematic review s of r and omised controlled trials of adult patients , admitted to the intensive care unit and who have received physical rehabilitation interventions at any time point during their recovery . Data extraction will include systematic review aims and rationale , study types , population s , interventions , comparators , outcomes and quality appraisal method . Primary outcomes of interest will focus on findings reflecting recovery of physical function . Quality of reporting and method ological quality will be appraised using the PRISMA checklist and the Assessment of Multiple Systematic Review s tool . Discussion We anticipate the findings from this novel overview of systematic review s will contribute to the synthesis and interpretation of existing evidence regarding physical rehabilitation interventions and physical recovery in post-critical illness patients across the continuum of recovery . Systematic review registration PROSPERO CRD42015001068 Background Ageing is associated with a decrease in physical activity . This decrease particularly occurs during specific transitional life stages . Especially during adolescence and young adulthood a steep decrease in physical activity is observed . Inactive people are often not aware of their inactivity . Providing feedback on the actual physical activity level by an activity monitor can increase awareness and may in combination with an individually tailored physical activity advice stimulate a physically active lifestyle . Methods In a r and omized controlled trial the effectiveness of providing an activity monitor in combination with a personal physical activity advice through the Internet will be examined . Outcome measures are level of physical activity , determinants of physical activity , quality of life , empowerment , aerobic fitness and body composition .  Participants are relatively inactive adolescents and young adults who are measured at baseline , after 3 months intervention and 5 months after the end of the intervention . In addition , facilitating and hindering factors for implementation of the intervention will be investigated . Discussion The use of a personal activity monitor in combination with web-based assisted individually tailored health promotion offers a good opportunity to work interactively with large groups of adolescents and young adults and provide them with advice based on their actual activity level . It has great potential to motivate people to change their behaviour and to our knowledge has not been evaluated before Background The construct of total wellness includes a holistic approach to the body , mind and spirit components of life . While the health benefits of reducing sedentary behavior and increasing physical activity are well documented , little is known about the influence on total wellness of an internet-based physical activity monitor design ed to help people to achieve higher physical activity levels . Purpose The purpose of this four-week , personal activity monitor-based intervention program was to reduce sedentary behavior and increase physical activity levels in daily living for sedentary adults and to determine if these changes would also be associated with improvement in total wellness . Methods Twenty-two men and 11 women ( 27 years ± 4.0 ) were r and omly assigned to either an intervention ( n = 18 ) or control group ( n = 15 ) . The intervention group interacted with an online personal activity monitor ( Gruve Solution ™ ) design ed to reduce sedentary time  and increase physical activity during activities of daily living . The control group did not interact with the monitor , as they were asked to follow their normal daily physical activities and sedentary behavior routines . The Wellness Evaluation of Lifestyle ( WEL ) inventory was used to assess total wellness . Sedentary time , light , walking , moderate and vigorous intensity physical activities were assessed for both intervention and control groups at baseline and at week-4 by the 7-day Sedentary and Light Intensity Physical Activity Log ( 7-day SLIPA Log ) and the International Physical Activity Question naire ( IPAQ ) . Results Significant increases in pre-post total wellness scores ( from 64 % ± 5.7 to 75 % ± 8.5 ) ( t ( 17 ) = -6.5 , p < 0.001 ) were observed in the intervention group by the end of week four . Intervention participants decreased their sedentary time ( 21 % , 2.3 hours/day ) and increased their light ( 36.7 % , 2.5 hours/day ) , walking ( 65 % , 1057 MET-min/week ) , moderate ( 67 % , 455 MET-min/week ) and vigorous intensity ( 60 % , 442 MET-min/week ) physical activity ( all p < 0.001 ) . No significant differences for total wellness were observed between the groups at baseline and no pre-post significant differences were observed for any outcome variable in the control group . Conclusion Total wellness is improved when sedentary , but sufficiently physically active adults , reduce sedentary time and increase physical activity levels ( i.e. light , waking , moderate and vigorous ) Background As adults age , their physical activity decreases and sedentary behavior increases , leading to increased risk of negative health outcomes .  Wearable electronic activity monitors have shown promise for delivering effective behavior change techniques . However , little is known about the feasibility and acceptability of non-Fitbit wearables ( Fitbit , Inc , San Francisco , California ) combined with telephone counseling among adults aged more than 55 years . Objective The purpose of our study was to determine the feasibility , acceptability , and effect on physical activity of an intervention combining a wearable physical activity monitor , tablet device , and telephone counseling  among adults aged 55 - 79 years . Methods Adults ( N=40 , aged 55 - 79 years , body mass index=25 - 35 , < 60 min of activity per week ) were r and omized to receive a 12-week intervention or to a wait list control . Intervention participants received a Jawbone Up24 monitor , a tablet with the Jawbone Up app installed , and brief weekly telephone counseling . Participants set daily and weekly step goals and used the monitor ’s idle alert to notify them when they were sedentary for more than 1 h. Interventionists provided brief counseling once per week by telephone .  Feasibility was measured using observation and study records , and acceptability was measured by self-report using vali date d items . Physical activity and sedentary time were measured using ActivPAL monitors following st and ard protocol s. Body composition was measured using dual-energy x-ray absorptiometry scans , and fitness was measured using a 6-min walk test . Results Participants were 61.48 years old ( SD 5.60 ) , 85 % ( 34/40 ) female , 65 % ( 26/40 ) white .  Average activity monitor wear time was 81.85 ( SD 3.73 ) of 90 days . Of the 20 Up24 monitors , 5 were reported broken and 1 lost . No related adverse events were reported . Acceptability items were rated at least 4 on a scale of 1 - 5 . Effect sizes for most outcomes were small , including stepping time per day ( d=0.35 ) , steps per day ( d=0.26 ) , sitting time per day ( d=0.21 ) , body fat ( d=0.17 ) , and weight ( d=0.33 ) . Conclusions The intervention was feasible and acceptable in this population . Effect sizes were similar to the sizes found using other wearable electronic activity monitors , indicating that when combined with telephone counseling , wearable activity monitors are a potentially effective tool for increasing physical activity and decreasing sedentary behavior . Trial registration Clinical trials.gov NCT01869348 ; https:// clinical trials.gov/ct2/show/NCT01869348 ( Archived by WebCite at http://www.webcitation.org/6odlIolqy PURPOSE To examine the effect of resistance exercises on self-reported physical function and activities of daily living ( ADL ) in older adults with osteoporosis or osteopenia . METHODS A search of available literature was conducted using PubMed , CINAHL , SPORTD iscus , PEDro , ProQuest Nursing and Allied Health Source , and Cochrane Controlled Trials Register . Studies were included if they involved ( 1 ) r and omized controlled trials ; ( 2 ) participants with osteoporosis or osteopenia ; ( 3 ) resistance exercise as an intervention ;  and ( 4 ) self-report of physical function or ADL . Articles were independently review ed for quality by two authors using the Physiotherapy Evidence Data base ( PEDro ) scale . Cohen 's d effect size was calculated by dividing st and ardized mean differences by the st and ard deviation to determine treatment effect in terms of physical function or ADL . RESULTS Five full-text articles were selected for inclusion . PEDro scores ranged from 5 to 7 ( out of 10 ) . Effect size mean differences as a result of resistance intervention ranged from 0.08 to 1.74 , suggesting " trivial " to " large " effects on self-reported physical function and ADL . CONCLUSION RESULTS suggest that interventions using resistance training have a beneficial impact on the domains of physical function and ADL in participants with osteoporosis or osteopenia . More high- quality studies are needed to lend further validity to this supposition Background Online social networks offer considerable potential for delivery of socially influential health behavior change interventions . Objective To determine the efficacy , engagement , and feasibility of an online social networking physical activity intervention with pedometers delivered via Facebook app . Methods A total of 110 adults with a mean age of 35.6 years ( SD 12.4 ) were recruited online in teams of 3 to 8 friends . Teams were r and omly allocated to receive access to a 50-day online social networking physical activity intervention which included self-monitoring , social elements , and pedometers ( “ Active Team ” Facebook app ; n=51 individuals , 12 teams ) or a wait-listed control condition ( n=59 individuals , 13 teams ) . Assessment s were undertaken online at baseline , 8 weeks , and 20 weeks . The primary outcome measure was self-reported weekly moderate-to-vigorous physical activity ( MVPA ) . Secondary outcomes were weekly walking , vigorous physical activity time , moderate physical activity time , overall quality of life , and mental health quality of life . Analyses were undertaken using r and om-effects mixed modeling , accounting for potential clustering at the team level . Usage statistics were reported descriptively to determine engagement and feasibility . Results At the 8-week follow-up , the intervention participants had significantly increased their total weekly MVPA by 135 minutes relative to the control group ( P=.03 ) , due primarily to increases in walking time ( 155 min/week increase relative to controls , P<.001 ) . However , statistical differences between groups for total weekly MVPA and walking time were lost at the 20-week follow-up . There were no significant changes in vigorous physical activity , nor overall quality of life or mental health quality of life at either time point . High levels of engagement with the intervention , and particularly the self-monitoring features , were observed . Conclusions An online , social networking physical activity intervention with pedometers can produce sizable short-term physical activity changes . Future work is needed to determine how to maintain behavior change in the longer term , how to reach at-need population s , and how to disseminate such interventions on a mass scale . Trial Registration Australian New Zeal and Clinical Trials Registry ( ANZCTR ) : ACTRN12614000488606 ; https://www.anzctr.org.au/Trial/ Registration /Trial Review .aspx?id=366239 ( Archived by WebCite at http://www.webcitation.org/6ZVtu6TMz ) Background Many postnatal women are insufficiently physically active in the year after childbirth and could benefit from interventions to increase activity levels . However , there is limited information about the efficacy , feasibility and acceptability of motivational and behavioral interventions promoting postnatal physical activity in the UK . Methods The MAMMiS study is a r and omized , controlled trial , conducted within a large National Health Service ( NHS ) region in Scotl and . Up to 76 postnatal women will be recruited to test the impact of two physical activity consultations and a 10-week group pram-walking program on physical activity behavior change . The intervention uses evidence -based motivational and behavioral techniques and will be systematic ally evaluated using objective measures ( accelerometers ) at three months , with a maintenance measure taken at a six-month follow-up . Secondary health and well-being measures and psychological mediators of physical activity change are included . Discussion The ( MAMMiS study will provide a test of a theoretical and evidence -based physical activity behavior change intervention for postnatal women and provide information to inform future intervention development and testing within this population .Trial registration Current Controlled Trials IS RCT Background The aim of these review s is to inform the design and content of interventions to reduce obesity in young children . The behaviors that are associated with obesity/overweight have been studied extensively ; however , the factors associated with these behaviors in young children ( 0 to 6 years ) have not been systematic ally review ed . Over the past few years the focus of obesity prevention has shifted to preschool children because of the high prevalence of obesity at school entry and recognition that habits formed in early life could track into adulthood . In order to develop effective interventions and change behavior , it is important to underst and the factors that are associated with those behaviors . For example , we need to underst and whether it would be more important to target the family , childcare setting s or the wider environment and identify the most effective way of changing these energy balance related behaviors . Methods / Design Quantitative ( intervention and observational ) and qualitative literature on determinants/correlates of fruit and vegetable intake , sugar sweetened beverage and other unhealthy diet intake , and physical activity and sedentary behaviors in young children will be systematic ally identified , mapped and review ed . A common search strategy ( no language or period restrictions ) will be used to identify papers from eight electronic data bases and this will be supplemented by h and - search ing . Next , studies in developed countries that examine the factors associated with these behaviors in children aged 0 to 6 years ( at baseline ) will be screened and mapped descriptively followed by in-depth data extraction , quality assessment and synthesis . Data from quantitative studies will be summarized using either forest plots or harvest plots and narrative synthesis , and qualitative studies using thematic analysis . Qualitative evidence will be integrated with the quantitative evidence , using a parallel synthesis approach , to provide a deeper underst and ing of effective strategies to influence these energy balance related behaviors . Discussion In addition to updating and mapping current research , these review s will be the first to comprehensively synthesize and integrate both the quantitative and qualitative evidence pertaining to determinants/correlates/barriers/facilitators of obesity related behaviors in this young age group ( 0 to 6 years ) with the aim of informing future interventions . Systematic review registration International Prospect i ve Register for Systematic Review s ( PROSPERO ) Registration number : PURPOSE To describe the theoretical rationale , intervention design , and clinical trial of a two-year weight control intervention for young adults deployed via social and mobile media . METHODS A total of 404 overweight or obese college students from three Southern California universities ( M(age ) = 22 ( ± 4 ) years ; M ( BMI ) = 29 ( ± 2.8 ) ; 70 % female ) were r and omized to participate in the intervention or to receive an informational web-based weight loss program . The intervention is based on behavioral theory and integrates intervention elements across multiple touch points , including Facebook , text messaging , smartphone applications , blogs , and e-mail . Participants are encouraged to seek social support among their friends , self-monitor their weight weekly , post their health behaviors on Facebook , and e-mail their weight loss questions /concerns to a health coach . The intervention is adaptive because new theory-driven and iteratively tailored intervention elements are developed and released over the course of the two-year intervention in response to patterns of use and user feedback . Measures of body mass index , waist circumference , diet , physical activity , sedentary behavior , weight management practice s , smoking , alcohol , sleep , body image , self-esteem , and depression occur at 6 , 12 , 18 , and 24 months . Currently , all participants have been recruited , and all are in the final year of the trial . CONCLUSION Theory-driven , evidence -based strategies for physical activity , sedentary behavior , and dietary intake can be embedded in an intervention using social and mobile technologies to promote healthy weight-related behaviors in young adults Background The purpose was to conduct systematic review s of the relationship between physical activity of healthy community-dwelling older ( > 65 years ) adults and outcomes of  functional limitations , disability , or loss of independence .  Methods Prospect i ve cohort studies with an outcome related to functional independence or to cognitive function  were search ed , as well as exercise training interventions that reported a functional outcome . Electronic data base search strategies were used to identify citations which were screened ( title and abstract ) for inclusion . Included articles were review ed to complete st and ardized data extraction tables , and assess study quality . An established system of assessing the level and grade of evidence for recommendations was employed . Results Sixty-six studies met inclusion criteria for the relationship between physical activity and functional independence , and 34 were included with a cognitive function outcome . Greater physical activity of an aerobic nature ( categorized by a variety of methods ) was associated with higher functional status ( expressed by a host of outcome measures ) in older age . For functional independence , moderate ( and high ) levels of physical activity appeared effective in conferring a reduced risk ( odds ratio ~0.5 ) of functional limitations or disability . Limitation in higher level performance outcomes was reduced ( odds ratio ~0.5 ) with vigorous ( or high ) activity with an apparent dose-response of moderate through to high activity . Exercise training interventions ( including aerobic and resistance ) of older adults showed improvement in physiological and functional measures , and suggestion of longer-term reduction in incidence of mobility disability . A relatively high level of physical activity was related to better cognitive function and reduced risk of developing dementia ; however , there were mixed results of the effects of exercise interventions on cognitive function indices . Conclusions There is a consistency of findings across studies and a range of outcome measures related to functional independence ; regular aerobic activity and short-term exercise programmes confer a reduced risk of functional limitations and disability in older age . Although a precise characterization of a minimal or effective physical activity dose to maintain functional independence is difficult , it appears moderate to higher levels of activity are effective and there may be a threshold of at least moderate activity for significant outcomes ABSTRACT Lack of  physical activity  (  PA  ) and high levels of sedentary behaviour ( SB ) have been associated with health problems . This systematic review evaluates the effectiveness of school-based interventions to increase PA  and decrease SB  among 15–19-year-old adolescents , and examines whether intervention characteristics ( intervention length , delivery mode and intervention provider ) and intervention content ( i.e. behaviour change techniques , BCTs ) are related to intervention effectiveness . A systematic search of r and omised or cluster r and omised controlled trials with outcome measures of PA and /or SB rendered 10 results . Risk of bias was assessed using the Cochrane risk of bias tool . Intervention content was coded using Behaviour Change Technique Taxonomy v1 . Seven out of 10 studies reported significant increases in PA . Effects were generally small and short-term ( Cohen 's d ranged from 0.132 to 0.659 ) . Two out of four studies that measured SB reported significant reductions in SB . Interventions that increased PA  included a higher number of BCTs , specific BCTs ( e.g. , goal setting , action planning and self-monitoring ) , and were delivered by research staff . Intervention length and mode of delivery were unrelated to effectiveness . More studies are needed that evaluate long-term intervention effectiveness and target SBs among older adolescents BACKGROUND Underserved children , particularly girls and those in urban communities , do not meet the recommended physical activity guidelines ( > 60min of daily physical activity ) , and this behavior can lead to obesity . The school years are known to be a critical period in the life course for shaping attitudes and behaviors . Children look to schools for much of their access to physical activity . Thus , through the provision of appropriate physical activity programs , schools have the power to influence apt physical activity choices , especially for underserved children where disparities in obesity-related outcomes exist . OBJECTIVES To evaluate the impact of a nurse directed , coordinated , culturally sensitive , school-based , family-centered lifestyle program on activity behaviors and body mass index . DESIGN , SETTING S AND PARTICIPANTS This was a parallel group , r and omized controlled trial utilizing a community-based participatory research approach , through a partnership with a University and 5 community schools . Participants included 251 children ages 8 - 12 from elementary schools in urban , low-income neighborhoods in Los Angeles , USA . METHODS The intervention included Kids N Fitness ( © ) , a 6-week program which met weekly to provide 45min of structured physical activity and a 45min nutrition education class for parents and children . Intervention sites also participated in school-wide wellness activities , including health and counseling services , staff professional development in health promotion , parental education newsletters , and wellness policies for the provision of healthy foods at the school . The Child and Adolescent Trial for Cardiovascular Health School Physical Activity and Nutrition Student Question naire measured physical activity behavior , including : daily physical activity , participation in team sports , attending physical education class , and TV viewing/computer game playing . Anthropometric measures included height , weight , body mass index , resting blood pressure , and waist circumference . Measures were collected at baseline , completion of the intervention phase ( 4 months ) , and 12 months post-intervention . RESULTS Significant results for students in the intervention , included for boys decreases in TV viewing ; and girls increases in daily physical activity , physical education class attendance , and decreases in body mass index z-scores from baseline to the 12 month follow-up . CONCLUSIONS Our study shows the value of utilizing nurses to implement a culturally sensitive , coordinated , intervention to decrease disparities in activity and TV viewing among underserved girls and boys
No impact of patient and intervention characteristics on the effect estimates were found .
Short conclusion Low quality of evidence was found for a moderate effect of physical activity monitor-based interventions on physical activity compared with control interventions .
Background The body of evidence related to the effect of physical activity monitor-based interventions has grown over the recent years .
However , the effect of physical activity monitor-based interventions in older adults remains unclear and should be systematic ally review ed .
Objective The objective of this systematic review was to estimate the effect of physical activity monitor-based interventions on physical activity behavior  in participants aged 65 and above .
Subsequently we explored the effect on body mass index , physical capacity , and health-related quality of life and finally the impact of patient- and intervention characteristics .
