Type 2 diabetes ( T2D ) has attained the status of a global p and emic , spreading from affluent industrialized nations to the emerging economies of Asia , Latin America , and Africa . There is significant global variation in susceptibility to T2D , with Pacific Isl and ers , Asian Indians , and Native Americans being considerably more prone to develop the disorder . Although genetic factors may play a part , the rapidity with which diabetes prevalence has risen among these population s reflects the far-ranging and rapid socioeconomic changes to which they have been exposed over the past few decades . Traditionally , obesity and its correlate , insulin resistance , have been considered the major mediators of T2D risk ; however , recent evidence shows that early loss of β-cell function plays an important role in the pathogenesis of T2D , especially in nonobese individuals such as South Asians . Knowledge of the modifiable risk factors of T2D is important , as it forms the basis for design ing cost-effective preventive and therapeutic strategies to slow the epidemic in population s at increased risk . Lessons learned from r and omized prevention trials need to be implemented with appropriate cultural adaptations , accompanied by empowerment of the community , if the diabetes epidemic is to be slowed or halted Diabetes is an “ old disease ” . The first description of diabetes written on papyrus about 3500 years ago is found in the Ebers papyrus  , which was discovered in Egypt in 1873 by the German archeologist Georg Ebers . Humans , like most mammals , may develop diabetes , if sufficient environmental exposure to physical inactivity , unhealthy diet and obesity are present . Genetic effects are important for the individual risk of type 2 diabetes ( T2D ) but twin studies have shown that the genetic effects combined explain less than 50 % of the risk of T2D ( 1 ) . Today we know almost 100 susceptibility genes associated with T2D but the relative importance of each of these genes is low ( 2 ) , and together they explain only a small part of the disease risk . Thus , genetic screening can not be used for the prediction of T2D for individuals . On the other h and , healthy lifestyle can also prevent T2D in people who are genetically at high risk , e.g. those with positive family history ( 3 ) . Thus , the importance of lifestyle factors for the development and prevention of T2D is overwhelming . The strongest evidence in medicine is considered to come from r and omized controlled trials ( RCTs ) . They are also important in providing the link to causal inference that in most observational studies can not be derived . At the same time , observational studies are necessary for the identification of factors associated with an increased or decreased risk of a disease , and for generation of hypotheses on potential means for prevention based on modifiable risk factors . Observational studies have by now identified a large number of factors that are associated with the development of T2D or with the protection against it . Most of them are related to physical activity , diet and obesity . It has also been shown unequivocally that exposures ( poor nutrition , infections , smoking , etc . ) during fetal life and early infancy result ing in insufficient development ( often shown as low birth weight ) also predict T2D later in life ( 4 ) . Traditionally , T2D has been considered to be a disease of the elderly . However , with increasing obesity and sedentary lifestyle in children , there are increasing numbers of cases of T2D already occurring at a young age in many population s ( 5 ) . In the past two decades several innovative RCTs have repeatedly shown that interventions on modifiable risk factors can reduce the incidence of diabetes in high-risk groups . The evidence has been summarized in several systematic review s and meta-analyses ( 6,7 ) . There is compelling scientific evidence from RCTs that T2D can be prevented or its onset delayed . The key for prevention is a multimodal package of lifestyle changes that is a sum outcome of dietary and physical activity behaviours . The power of lifestyle was dramatically illustrated by the Finnish Diabetes Prevention Study ( DPS ) that explicitly showed that when the study participants with impaired glucose tolerance reached all five modest lifestyle intervention targets , none of them progressed to T2D ( 8) . Importantly , lifestyle intervention lasting for 3–6 years has been shown to have a carry-over effect on T2D incidence that lasts for several years ; up to 15 in the Finnish Diabetes Prevention Study ( 9 ) and 20 years in the China Da Qing Diabetes Prevention Study ( 10 ) . The observed sustained risk reduction seems to be a result of sustained lifestyle changes , but the legacy effect of improved glycaemia during the early intervention may also have contributed to the long-term effect . The follow-up data from the Chinese study indicate moreover that vascular risks are also reduced by lifestyle management . Several prognostic question naires exist for detecting people at risk of T2D ( 11 ) . One of the screening tools with an adequately high sensitivity and specificity is the Finnish Diabetes Risk Score ( FINDRISC ) developed in Finl and ( 12 ) . The FINDRISC has been successfully implemented in the Finnish primary health care system and used also in many other countries . The FINDRISC was also tested in the Omani population and as a result a slightly modified Omani Diabetes Risk Score was developed ( 13 ) which may be a suitable screening tool for the Arab population s in the Middle East . Lifestyle interventions aim ing at translating evidence from efficacy RCTs on T2D prevention into “ real world ” intervention programmes have also been carried out in various population s. Such data were recently combined in a meta- analysis considering the relationship between intervention effectiveness and adherence to guidelines ( 14 ) . The primary meta- analysis included 22 studies with outcome data for weight loss at 12 months . The pooled result of the direct pairwise meta- analysis shows that Background : Research on the translation of efficacious lifestyle change programs to prevent type 2 diabetes into community or clinical setting s is needed . Objective : The objective of this study was to examine the reach , implementation , and efficacy of a 6-month lifestyle program implemented in primary care by nurse practitioners ( NPs ) for adults at risk of type 2 diabetes . Methods : The NP sites ( n = 4 ) were r and omized to an enhanced st and ard care program ( one  NP  and one  nutrition session ) or a lifestyle program ( enhanced st and ard care and six NP sessions ) . These NPs recruited adults at risk of diabetes from their practice ( n = 58 ) , with an acceptance rate of 70 % . Results : The program reached a diverse , obese , and moderately low income sample . The NPs were able to successfully implement the protocol s. The average length of the program was 9.3 months . Attendance was high ( 98 % ) , and attrition was low ( 12 % ) . The NPs were able to adopt the educational , behavioral , and psychosocial strategies of the intervention easily . Motivational interviewing was more difficult for NPs . Mixed-model repeated- measures analysis indicated significant trends or improvement in both groups for nutrition and exercise behavior . Participants of the lifestyle program demonstrated trends for better high-density lipoprotein ( HDL ) and exercise behavior compared with the enhanced st and ard care participants . Twenty-five percent of lifestyle participants met treatment goals of 5 % weight loss compared with 11 % of st and ard care participants . Discussion : A lifestyle program can be implemented in primary care by NPs , reach the targeted population , and be modestly successful . Further research is indicated Background Type 2 diabetes is a major public health problem in Australia with prevalence increasing in parallel with increasing obesity . Prevention is an essential component of strategies to reduce the diabetes burden . There is strong and consistent evidence from r and omised controlled trials that type 2 diabetes can be prevented or delayed through lifestyle modification which improves diet , increases physical activity and achieves weight loss in at risk people . The current challenge is to translate this evidence into routine community setting s , determine feasible and effective ways of delivering the intervention and providing on-going support to sustain successful behavioural changes . Methods / Design The Sydney Diabetes Prevention Program ( SDPP ) is a translational study which will be conducted in 1,550 participants aged 50 - 65 years ( including 100 indigenous people aged 18 years and older ) at high risk of future development of diabetes . Participants will be identified through a screening and recruitment program delivered through primary care and will be offered a community-based lifestyle modification intervention . The intervention comprises an initial individual session and three group sessions based on behaviour change principles and focuses on five goals : 5 % weight loss , 210 min/week physical activity ( aerobic and strength training exercise ) , limit dietary fat and saturated fat to less than 30 % and 10 % of energy intake respectively , and at least 15 g/1000 kcal dietary fibre . This is followed by 3-monthly contact with participants to review progress and offer ongoing lifestyle advice for 12 months . The effectiveness and costs of the program on diabetes-related risk factors will be evaluated . Main outcomes include changes in weight , physical activity , and dietary changes ( fat , saturated fat and fibre intake ) . Secondary outcomes include changes in waist circumference , fasting plasma glucose , blood pressure , lipids , quality of life , psychological well being , medication use and health service utilization . Discussion This translational study will ascertain the reach , feasibility , effectiveness and cost-effectiveness of a lifestyle modification program delivered in a community setting through primary health care . If demonstrated to be effective , it will result in recommendations for policy change and practical methods for a wider community program for preventing or delaying the onset of type 2 diabetes in high risk people Background Prevalence of type 2 diabetes ( T2D ) is increasing worldwide . T2D prevention by lifestyle intervention is effective . Pragmatic scalable interventions are needed , with evidence to efficiently target and monitor such interventions . We report pooled analyses of data from three European trial cohorts : to analyse T2D incidence , sustained weight loss and utility of risk predictors . Methods We analysed data on 749 adults with impaired glucose tolerance ( 278 men and 471 women , mean age 56 years , mean BMI 31 kgm−2 ) recruited between 1993 and 2003 , and r and omised to intensive lifestyle intervention ( I ) or lifestyle advice control ( C ) . The intervention aim ed to increase physical activity , modify diet , and promote weight loss≥5 % . Using Cox-regression survival analysis , we assessed T2D incidence and the impact on T2D incidence of sustained weight loss , and of baseline cut-point values of FINDRISC score , fasting plasma glucose ( FPG ) , and HbA1c . Results Mean follow-up duration was 3.1 years . T2D was diagnosed in 139 participants ( I = 45/379 , C = 94/370 ) . Cumulative T2D incidence was 57 % lower in the intervention compared with the control group ( HR 0.42 ( 95 % CI 0.29 to 0.60 ) P<0.001 ) . Participants with ≥5 % weight loss at one year had 65 % lower T2D incidence ( HR 0.35 ( 95 % CI 0.22 to 0.56 ) P<0.001 ) ; maintaining ≥5 % weight loss for two and three years further reduced T2D incidence . Recommended cut-points to identify those at high risk for T2D would have identified different proportions of European Diabetes Prevention Study ( EDIPS ) participants with similar hazard-ratios for intervention effect . Conclusions Pooled analysis of EDIPS trial data reinforces evidence for T2D prevention by lifestyle intervention . Analysis showed the preventive effect of ≥5 % weight loss , especially if maintained long term , which has utility for intervention monitoring . Analysis of proposed cut-points demonstrates difficulties in balancing risk and benefit , to efficiently target interventions and suggests evidence is needed to define clinical policy .

Although dietary and physical activity interventions may reduce the risk of T2D , the effectiveness has been moderate among South Asians . This might ( in part ) be because this subgroup follows strategies that were originally developed for interventions among other population s. Therefore , this review aims to assess the evidence for the current dietary and physical activity strategies recommended in T2D prevention intervention studies and guidelines for South Asians . Methods and analysis Included will be all studies and guidelines on dietary and /or physical activity strategies to prevent T2D in adult South Asians . Two review ers will search online data bases from their start until the present date for published and unpublished experimental/quasiexperimental studies , with at least an abstract in English . References of identified articles and key review s will be screened for additional studies . Guidelines will be identified by search es in online data bases and websites of public organisations . Finally , expert consultations will be held to supplement any missing information . Trial quality will be assessed with the Quality Assessment Tool for Quantitative Studies Data , and guidelines with the Appraisal of Guidelines for Research & Evaluation II . Data on the strategies recommended , targeting and evidence on effectiveness will be extracted by two review ers and presented in tabular and narrative forms . Recommendations will be compared with the National Institute for Health and Care Excellence guidelines [ PH35 ] . Overall findings on  dietary and physical activity recommendations , as well as findings for specific subgroups ( eg , by sex ) , will be discussed . Ethics and dissemination Ethics assessment is not required . Start date : 1 January 2016 , finishing and reporting date 31 July 2016 . Results will be published in a peer- review ed scientific journal , the project report of EuroDHYAN ( www.eurodhyan.eu ) and in a PhD dissertation . Trial registration number The protocol is registered with the International Prospect i ve Register of Systematic Review s ( PROSPERO ) registration number CRD42015027067 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 The objective was to take prevention from the clinic to the community by including a high-risk group and working with the community to tailor , enhance , deliver , and evaluate a community-based version of the Diabetes Prevention Program ’s ( DPP ) clinic-based lifestyle intervention . Methods This was a nonr and omized prospect i ve study using a single-group design . Study eligibility included a screening glucose value in the normal to prediabetes range with no current diagnosis of diabetes , overweight , not pregnant nor planning to become pregnant during study period , aged 18 to 65 , Latino , living in the study target communities , and no reported medical restrictions related to the program goals . A total of 69 individuals participated . The Healthy Living Program ( HLP ) was based on the DPP ’s 1-year intensive lifestyle program , was tailored and enhanced for a Latino community , and was delivered by community health workers . Anthropometric and paper and pencil measures were administered to examine program outcome at 6 months and 12 months . Results In general , results indicate statistically significant improvements in anthropometrics and many behavioral outcomes , particularly at 6 months . Participants demonstrated forward movement through the stages of change during the program . Conclusions Results support the effectiveness of the intervention and show that delivery of the translated version of the DPP ’s lifestyle intervention in the community by community residents holds promise as one strategy to reach people at increased risk of developing diabetes . Use of this translation model , including collaboration with community health workers , offers diabetes educators an opportunity to extend their reach into underserved communities Type 2 diabetes is a global public health crisis that threatens the economies of all nations , particularly developing countries . Fueled by rapid urbanization , nutrition transition , and increasingly sedentary lifestyles , the epidemic has grown in parallel with the worldwide rise in obesity . Asia 's large population and rapid economic development have made it an epicenter of the epidemic . Asian population s tend to develop diabetes at younger ages and lower BMI levels than Caucasians . Several factors contribute to accelerated diabetes epidemic in Asians , including the “ normal-weight metabolically obese ” phenotype ; high prevalence of smoking and heavy alcohol use ; high intake of refined carbohydrates ( e.g. , white rice ) ; and dramatically decreased physical activity levels . Poor nutrition in utero and in early life combined with overnutrition in later life may also play a role in Asia 's diabetes epidemic . Recent advances in genome-wide association studies have contributed substantially to our underst and ing of diabetes pathophysiology , but currently identified genetic loci are insufficient to explain ethnic differences in diabetes risk . Nonetheless , interactions between Westernized diet and lifestyle and genetic background may accelerate the growth of diabetes in the context of rapid nutrition transition . Epidemiologic studies and r and omized clinical trials show that type 2 diabetes is largely preventable through diet and lifestyle modifications . Translating these findings into practice , however , requires fundamental changes in public policies , the food and built environments , and health systems . To curb the escalating diabetes epidemic , primary prevention through promotion of a healthy diet and lifestyle should be a global public policy priority AIMS The Diabetes Community Lifestyle Improvement Program ( D-CLIP ) aims to implement and evaluate in a controlled , r and omized trial the effectiveness , cost-effectiveness , and sustainability of a culturally appropriate , low-cost , and sustainable lifestyle intervention for the prevention of type 2 diabetes mellitus in India . METHODS D-CLIP , a translational research project adapted from the methods and curriculum developed and tested for efficacy in the Diabetes Prevention Program , utilizes innovated methods ( a step-wise model of diabetes prevention with lifestyle and metformin added when needed ; inclusion of individuals with isolated glucose tolerance , impaired fasting glucose , and both ; classes team-taught by professionals and trained community educators ) with the goals of increasing diabetes prevention , community acceptability , and long-term dissemination and sustainability of the program . The study outcomes are : diabetes incidence ( primary measure of effectiveness ) , cost-effectiveness , changes in anthropometric measures , plasma lipids , blood pressure , blood glucose , and HbA(1c , ) Program acceptability and sustainability will be assessed using a mixed methods approach . CONCLUSION D-CLIP , a low-cost , community-based , research program , addresses the key components of translational research and can be used as a model for prevention of chronic diseases in other low and middle-income country setting A growing body of scientific evidence has linked dairy intake to a reduced  type 2 diabetes ( T2D ) risk . Using an evidence -based approach , we review ed the most recent and strongest evidence on the relationship between dairy intake and the risk of T2D . Evidence indicates that dairy intake is significantly associated with a reduced T2D risk , and likely in a dose-response manner . The association between low-fat dairy and T2D risk reduction appears consistent . A beneficial impact is suggested for regular-fat dairy . The role of specific dairy products needs to be clarified . Potential underlying mechanisms include the role of dairy products in obesity and metabolic syndrome , as well as several dairy components , such as calcium , vitamin D , dairy fat , and specifically trans-palmitoleic acid . To conclude , there is strong , consistent , and accumulating evidence that dairy intake reduces the risk of T2D . More research is needed to better underst and the role of regular-fat and specific dairy products . Well- design ed r and omized controlled trials and mechanistic studies are needed to support these findings . Efforts to translate this evidence into clinical practice and public health guidance are needed Purpose Translating strategies and approaches from the successful clinical ly based Diabetes Prevention Program ’s lifestyle intervention to community setting s is a key next step . This article describes a lifestyle program developed in partnership by research ers at a major university and public health professionals at a local health department . Methods The Live Well , Be Well ( LWBW ) program was design ed to meet the needs of lower income , minority , and low-literacy adults at risk for diabetes . It was adapted from interventions with demonstrated efficacy and delivered in Spanish and English by health department staff . The program consisted of a 6-month active phase and a 6-month maintenance phase and was primarily telephone based , with one in-person planning session and several group workshops . In-person and group sessions were held in convenient community-based setting s. Counselors provided education and skills training to modify diet and increase physical activity . Self-selected and attainable goal - setting and action plans were emphasized to enhance self-efficacy . LWBW is the intervention component of a r and omized trial with primary outcomes of fasting glucose , weight , and other clinical measures . Conclusions The program provides a unique translational model for implementing diabetes risk reduction programs for underserved population s. Individually tailored and non-prescriptive , it utilized existing health department infrastructure , focused on telephone counseling , used culturally appropriate , low-literacy material s , and was delivered in local , community-based facilities INTRODUCTION The prevalence and risk of Type 2 Diabetes ( T2D ) has dramatically increased over the past decade . Physical activity ( PA ) has significant benefits for the treatment and prevention of T2D . The aim of this study is to develop , implement and evaluate a community-based PA intervention to improve aerobic and muscular fitness among adults at risk of , or diagnosed with T2D . RESEARCH DESIGN AND METHODS The eCoFit pilot intervention will be evaluated using a r and omized controlled trial ( RCT ) design . The 20-week ( Phases 1 and 2 ) multi-component intervention was guided by Social Cognitive Theory , Health Action Process Approach Model , and Cognitive Behavior Therapy strategies . Phase 1 ( Weeks 1 - 10 ) includes : i ) 5 group face-to-face sessions consisting of outdoor training and cognitive mentoring ; and ii ) the use of the eCoFit smartphone application with a description of where and how to use the outdoor environment to be more physically active . Phase 2 ( Weeks 11 - 20 ) includes the use of the eCoFit smartphone application only . Assessment s are to be conducted at baseline , 10-weeks ( primary end-point ) and 20-weeks ( secondary end-point ) post-baseline . Primary outcomes are cardio-respiratory fitness and muscular fitness ( lower body ) . Secondary outcomes include physical , behavioral , mental health and quality of life , and social-cognitive outcomes . DISCUSSION eCoFit is an innovative , multi-component intervention , which integrates smartphone technology , social support and the outdoor physical environment to promote aerobic and resistance training PA among adults at risk of , or diagnosed with T2D . The findings will be used to guide future interventions and to develop and implement effective community-based prevention programs . TRIAL REGISTRATION Australian New Zeal and Clinical Trials Registry No : ACTRN12615000990527 Vascular disease is a leading cause of death and disability . While it is preventable , little is known about the feasibility or acceptability of implementing interventions to prevent vascular disease in Australian primary health care . We conducted a cluster r and omised controlled trial assessing prevention of vascular disease in patients aged 40 - 65 by providing a lifestyle modification program in general practice . Interviews with 13 general practice s in the intervention arm of this trial examined their views on implementing the lifestyle modification program in general practice setting s. Qualitative study , involving thematic analysis of semi-structured interviews with 11 general practitioners , four practice nurses and five allied health providers between October 2009 and April 2010 . Providing brief lifestyle intervention fitted well with routine health-check consultations ; however , acceptance and referral to the program was dependent on the level of facilitation provided by program coordinators . Respondents reported that patients engaged with the advice and strategies provided in the program , which helped them make lifestyle changes . Practice nurse involvement was important to sustaining implementation in general practice , while the lack of referral services for people at risk of developing vascular disease threatens maintenance of lifestyle changes as few respondents thought patients would continue lifestyle changes without long-term follow up . Lifestyle modification programs to prevent vascular disease are feasible in general practice but must be provided in a flexible format , such as being offered out of hours to facilitate uptake , with ongoing support and follow up to assist maintenance . The newly formed Medicare Locals may have an important role in facilitating lifestyle modification programs for this target group Introduction : Type 2 diabetes mellitus ( T2DM ) is a major health issue in New Zeal and Māori . Clinical trials have demonstrated potential for the prevention of T2DM , but whether community public health programmes aim ing to prevent diabetes are effective is untested . Objective : To describe the planning and design of an intervention aim ing to translate T2DM prevention clinical trial evidence into a community-wide population health intervention in a high risk predominantly Māori community . Approach : Community concerns about the diabetes burden were heard by the local diabetes nurse , herself a tribal member , and discussed with a locally raised academic . Project planning ensued . The intervention and its evaluation were design ed using a participatory community development model . The planned intervention had three components : community-wide health promotion initiatives conveying healthy lifestyle messages , community education and monitoring for identified high-risk individuals and their extended families , and a structural strategy aim ed at adapting local environments to support lifestyle changes . The evaluation plan involved interrupted time series surveys coupled with formative and process evaluations rather than a r and omised control trial design . Discussion : Consulting communities , validating community concerns and prioritising cultural and ethical issues were key steps . Time spent developing good relationships amongst the health provider and academic research team members at the outset proved invaluable , as the team were united in addressing the project planning and implementation challenges , such as funding obstacles that arose because of our ethically and culturally appropriate non-r and omised control trial evaluation design . The pre-intervention survey demonstrated high rates of diabetes ( 13 % ) , insulin resistance ( 33 % ) and risk factors , and provided evidence for positive , as opposed to negative , lifestyle intervention messages . Conclusion : Community-wide lifestyle interventions have the potential to reduce rates of type 2 diabetes and other chronic diseases in high-risk communities , but require a high level of commitment from the health sector and buy-in from the community . Adequate commitment , leadership , planning and re sources are essential Evidence from varied community setting s has shown that the Group Lifestyle Balance ( GLB ) Program and other adaptations of the Diabetes Prevention Program ( DPP ) intervention are effective in lowering diabetes risk . Most DPP data originated from studies of pre-diabetic whites , with only sparse evidence of the effect of DPP in African Americans ( AAs ) in community setting s. This paper describes the design , methods , baseline characteristics and cost effective measures , of a single-blinded , cluster-r and omized trial of a faith-based adaptation of the GLB program , Fit Body and Soul ( FBAS ) . The major aims are to test efficacy and cost utility of FBAS in twenty AA churches . R and omization occurred at the church level and 604 AA overweight/obese ( BMI ≥25kg/m(2 ) ) adults with fasting plasma glucose range from normal to pre-diabetic received either FBAS or a health-education comparison program . FBAS is a group-based , multi-level intervention delivered by trained church health advisors ( health professionals from within the church ) , with the goal of ≥7 % weight loss , achieved through increasing physical activity , healthy eating and behavior modification . The primary outcome is weight change at 12weeks post intervention . Secondary outcomes include hemoglobin A1C , fasting plasma glucose , waist circumference , blood pressure , physical activity level , quality of life measures , and cost-effectiveness . FBAS is the largest known cohort of AAs enrolled in a faith-based DPP translation . Reliance on health professionals from within the church for program implementation and the cost analysis are unique aspects of this trial . The design provides a model for faith-based DPPs and holds promise for program sustainability and widespread dissemination Background The diabetes of many patients is managed in general practice ; healthcare providers aim to promote healthful behaviors , such as healthful diet , adequate physical activity , and smoking cessation . These measures may decrease insulin resistance , improve glycemic control , lipid abnormalities , and hypertension . They may also prevent cardiovascular disease and complications of diabetes . However , professionals do not adhere optimally to guidelines for lifestyle counseling . Motivational interviewing to change the lifestyle of patients with type 2 diabetes is intended to improve diabetes care in accordance with the national guidelines for lifestyle counseling . Primary care nurses will be trained in motivational interviewing embedded in structured care in general practice . The aim of this paper is to describe the design and methods of a study evaluating the effects of the nurses ' training on patient outcomes . Methods / Design A cluster , r and omized , controlled trial involving 70 general practice s ( 35 practice s in the intervention arm and 35 in the control arm ) starting in March 2007 . A total of 700 patients with type 2 diabetes will be recruited . The patients in the intervention arm will receive care from the primary care nurse , who will receive training in an implementation strategy with motivational interviewing as the core component . Other components of this strategy will be adaptation of the diabetes protocol to local circumstances , introduction of a social map for lifestyle support , and educational and supportive tools for sustaining motivational interviewing . The control arm will be encouraged to maintain usual care . The effect measures will be the care process , metabolic parameters ( glycosylated hemoglobin , blood pressure and lipids ) , lifestyle ( diet , physical activity , smoking , and alcohol ) , health-related quality of life , and patients ' willingness to change behaviors . The measurements will take place at baseline and after 14 months . Discussion Applying motivational interviewing for patients with diabetes in primary care has been studied , but to our knowledge , no other study has yet evaluated the implementation and sustainability of motivating and involving patients in day-to-day diabetes care in general practice . If this intervention proves to be effective and cost-effective , large-scale implementation of this nurse-oriented intervention will be considered and anticipated . Trial registration Current Controlled Trials IS RCT N68707773 Effective , cost-effective , safe , and feasible interventions to improve lifestyle behavior in at-risk population s are needed in primary care . In the Hoorn Prevention Study , the authors implemented a theory-based lifestyle intervention in which trained practice nurses used an innovative combination of motivational interviewing ( MI ) and problem-solving treatment ( PST ) . This article presents the intervention ’s reach , effectiveness in terms of process outcomes , adoption , and implementation . Recruitment strategy and participant flow were documented accurately . The effectiveness in terms of determinants of behavioral change was measured using a vali date d question naire . Question naires were also used to assess participant satisfaction and compliance , as well as practice nurses ’ confidence in providing the intervention . Counseling sessions were tape recorded to assess MI , PST , and general counseling competence . The findings indicate that the recruitment strategy was adequate and result ed in a reasonably extensive reach of the target population . Practice nurses were competent and confident in their provision of  MI and PST  , and participant satisfaction was high . Nevertheless , the number of sessions attended was low , and almost no effects were seen on determinants of behavioral change . The authors conclude that implementing this type of intervention in primary care is feasible , but more is needed to effectively facilitate changes in determinants of lifestyle behavior in this population Type 2 diabetes ( T2D ) is a growing national health problem affecting 35 % of adults ≥20 years of age in the United States . Recently , diabetes has been categorized as an inflammatory disease , sharing many of the adverse outcomes as those reported from cardiovascular disease . Medical nutrition therapy is recommended for the treatment of diabetes ; however , these recommendations have not been up date d to target the inflammatory component , which can be affected by diet and lifestyle . To assess the current state of evidence for which dietary programs contain the most anti-inflammatory and glycemic control properties for patients with T2D , we conducted an integrative review of the literature . A comprehensive search of the PubMed , CINAHL , Scopus , and Web of Science data bases from January 2000 to May 2012 yielded 786 articles . The final 16 studies met the selection criteria including r and omized control trials , quasiexperimental , or cross-sectional studies that compared varying diets and measured inflammatory markers . The Mediterranean and DASH diets along with several low-fat diets were associated with lower inflammatory markers . The Mediterranean diet demonstrated the most clinical ly significant reduction in glycosylated hemoglobin ( HbA1c ) . Information on best dietary guidelines for inflammation and glycemic control in individuals with T2D is lacking . Continued research is warranted In the past few decades , prevention scientists have developed and tested a range of interventions with demonstrated benefits on  child and adolescent cognitive , affective , and behavioral health .  These evidence -based interventions offer promise of population -level benefit if accompanied by findings of implementation science to facilitate adoption , widespread implementation , and sustainment . Though there have been notable examples of successful efforts to scale up interventions , more work is needed to optimize benefit . Although the traditional pathway from intervention development and testing to implementation has served the research community well-allowing for a systematic advance of evidence -based interventions that appear ready for implementation-progress has been limited by maintaining the hypothesis that evidence generation must be complete prior to implementation . This sets up the challenging dichotomy between fidelity and adaptation and limits the science of adaptation to findings from r and omized trials of adapted interventions . The field can do better . This paper argues for the development of strategies to advance the science of adaptation in the context of implementation that would more comprehensively describe the needed fit between interventions and their setting s , and embrace opportunities for ongoing learning about optimal intervention delivery over time . Efforts to build the result ing adaptome ( pronounced " adapt-ohm " ) will include the construction of a common data platform to house systematic ally captured information about variations in delivery of evidence -based interventions across multiple population s and context s , and provide feedback to intervention developers , as well as the implementation research and practice communities . Finally , the article identifies next steps to jumpstart adaptome data platform development Background As in clinical practice re sources may be limited compared to experimental setting s , translation of evidence -based lifestyle interventions into daily life setting s is challenging . In this study we therefore evaluated the implementation of the APHRODITE lifestyle intervention for the prevention of type 2 diabetes in Dutch primary care . Based on this evaluation we discuss opportunities for refining intervention delivery . Methods A 2.5-year intervention was performed in 14 general practice s in the Netherl and s among individuals at high risk for type 2 diabetes ( FINDRISC-score ≥ 13 ) ( n = 479 ) and was compared to usual care ( n = 446 ) . Intervention consisted of individual lifestyle counselling by nurse practitioners ( n = 24 ) and GPs ( n = 48 ) and group-consultations .  Drop-out and attendance were registered during the programme . After the intervention , satisfaction with the programme and perceived implementation barriers were assessed with question naires . Results Drop-out was modest ( intervention : 14.6 % ; usual care : 13.2 % ) and attendance at individual consultations was high ( intervention : 80 - 97 % ; usual care : 86 - 94 % ) . Providers were confident about diabetes prevention by lifestyle intervention in primary care . Participants were more satisfied with counselling from nurse practitioners than from GPs . A major part of the GPs reported low self-efficacy regarding dietary guidance . Lack of counselling time ( 60 % ) , participant motivation ( 12 % ) , and financial reimbursement ( 11 % ) were regarded by providers as important barriers for intervention implementation . Conclusions High participant compliance and a positive attitude of providers make primary care a suitable setting for diabetes prevention by lifestyle counselling . Results support a role for the nurse practitioner as the key player in guiding lifestyle modification . Further research is needed on strategies that could increase cost-effectiveness , such as more stringent criteria for participant inclusion , group-counselling , more tailor-made counselling and integration of screening and / or interventions for different disorders Abstract Background Diabetes prevalence is increasing . The Finnish Diabetes Prevention Study ( DPS ) showed a 58 % reduction in Type 2 Diabetes ( T2D ) incidence in adults with impaired glucose tolerance ( IGT ) . The European Diabetes Prevention Study ( EDIPS ) extends the DPS to different European population s , using the same study design . In the Newcastle arm of this study ( EDIPS-Newcastle ) , we tested the hypothesis that T2D can be prevented by lifestyle intervention and explored secondary outcomes in relation to diabetes incidence . Methods We recruited 102 participants ( 42 men and 60 women , mean age 57 years , mean BMI 34 kgm-2 ) with IGT to EDIPS-Newcastle and r and omised to Intervention and usual care Control groups .  The intervention included individual motivational interviewing aim ed at : weight reduction , increase in physical activity , fibre and carbohydrate intake and reduction of fat intake ( secondary outcomes ) . The primary outcome was diagnosis of T2D . Results Mean duration of follow-up was 3.1 years . T2D was diagnosed in 16 participants ( I = 5 , C = 11 ) . Absolute incidence of T2D was 32.7 per 1000 person-years in the Intervention-group and 67.1 per 1000 person-years in the Control-group . The overall incidence of diabetes was reduced by 55 % in the Intervention-group , compared with the Control-group : RR 0.45 ( 95%CI 0.2 to 1.2).Explanatory survival analysis of secondary outcomes showed that those who sustained beneficial changes for two or more years reduced their risk of developing T2D . Conclusion Our results are consistent with other diabetes prevention trials . This study was design ed as part of a larger study and although the sample size limits statistical significance , the results contribute to the evidence that T2D can be prevented by lifestyle changes in adults with IGT . In explanatory analysis small sustained beneficial changes in weight , physical activity or dietary factors were associated with reduction in T2D incidence . Trial Registration International St and ard R and omised Controlled Trial Number registry ( IS RCT N)Registry number : IS RCT N 15670600 http://www.controlled-trials.com/is rct n/ search .html?srch=15670600%26sort=3%26dir = This paper describes a r and omized study to evaluate the effects of a comprehensive lifestyle management intervention for 279 postmenopausal women with type 2 diabetes who are at elevated risk for coronary heart disease ( CHD ) . The intervention , called the Mediterranean Lifestyle Trial , is focused on dietary factors , physical activity , social support and stress management . The Mediterranean Lifestyle Trial relies on a synthesis of Social Cognitive Theory and Social Ecologic Theory , as well as goal -systems theory , to explicitly inform the lifestyle intervention and to address maintenance . Thus , the trial should help illuminate the theoretical mechanisms responsible for lifestyle change . Primary outcome variables are dietary , stress management and physical activity behavior change , quality of life , and CHD-related biological risk factors . Hypothesized mediating variables include self-efficacy , coping , and social and environmental support . Following the initial 6-month intervention , participants in the intervention condition are r and omized to one of two groups design ed to enhance maintenance of effects : either a peer-led support group or a personalized multilevel community re sources maintenance condition . Unlike the peer group , the personalized approach focuses on multiple levels of community re sources to promote healthful lifestyle change . Because this research focuses on issues of generalization and translation to practice , the RE- AIM evaluation framework is being used to evaluate Reach , Effectiveness , Adoption , Implementation and Maintenance . This framework will help to translate research into practice by directing research ers ' attention to important but seldom-investigated strategies for enhancing longer-term maintenance . Specifically , the study tests how long-term maintenance may be improved through the use of existing community re sources , an intervention based on multiple environmental factors and multiple lifestyle behaviors , and lay leaders versus personalized professional support
RESULTS overall , lifestyle interventions were successful in reducing the incidence of T2D .
the available evidence shows that a robust behavioral change strategy is an essential part of an effective lifestyle modification program , as the absence of intensive individualized advice or " information only " more closely resembles the control group interventions used in these RCTs
UNLABELLED The worldwide epidemic of type 2 diabetes ( T2D ) emphasizes the need for guidelines regarding community implementation of lifestyle modification prevention programs .
An underst and ing of effective behavioral strategies is needed if evidence translation is to be realized .
The aim of this paper is to systematic ally review the behavioral change strategies for lifestyle T2D prevention programs .
