People living with HIV ( PLWH ) experience greater psychological distress than the general population . Evidence from high-incomes countries suggests that psychological interventions for PLWH can improve mental health symptoms , quality of life , and HIV care engagement . However , little is known about the effectiveness of mental health interventions for PLWH in low- and middle-income countries ( LMICs ) , where the large majority of PLWH reside . This systematized review aims to synthesize findings from mental health intervention trials with PLWH in LMICs to inform the delivery of mental health services in these setting s. A systematic search strategy was undertaken to identify peer- review ed published papers of intervention trials addressing negative psychological states or disorders ( e.g. depression , anxiety ) among PLWH in LMIC setting s. Search results were assessed against pre-established inclusion and exclusion criteria . Data from papers meeting criteria were extracted for synthesis . Twenty-six papers , published between 2000 and 2014 , describing 22 unique interventions were identified . Trials were implemented in sub-Saharan Africa ( n = 13 ) , Asia ( n = 7 ) , and the Middle East ( n = 2 ) , and addressed mental health using a variety of approaches , including cognitive-behavioral ( n = 18 ) , family-level ( n = 2 ) , and pharmacological ( n = 2 ) treatments . Four r and omized controlled trials reported significant intervention effects in mental health outcomes , and 11 preliminary studies demonstrated promising findings . Among the limited mental health intervention trials with PLWH in LMICs , few demonstrated efficacy .  Mental health interventions for PLWH in LMICs must be further developed and adapted for re source -limited setting s to improve effectiveness BACKGROUND Worldwide implementation of risk-based cardiovascular disease ( CVD ) prevention requires risk prediction tools that are contemporarily recalibrated for the target country and can be used where laboratory measurements are unavailable . We present two cardiovascular risk scores , with and without laboratory-based measurements , and the corresponding risk charts for 182 countries to predict 10-year risk of fatal and non-fatal CVD in adults aged 40 - 74 years . METHODS Based on our previous laboratory-based prediction model ( Globorisk ) , we used data from eight prospect i ve studies to estimate coefficients of the risk equations using proportional hazard regressions . The laboratory-based risk score included age , sex , smoking , blood pressure , diabetes , and total cholesterol ; in the non-laboratory ( office-based ) risk score , we replaced diabetes and total cholesterol with BMI . We recalibrated risk scores for each sex and age group in each country using country-specific mean risk factor levels and CVD rates . We used recalibrated risk scores and data from national surveys ( using data from adults aged 40 - 64 years ) to estimate the proportion of the population at different levels of CVD risk  for ten countries from different world regions as examples of the information the risk scores provide ; we applied a risk threshold for high risk of at least 10 % for high-income countries ( HICs ) and at least 20 % for low-income and middle-income countries ( LMICs ) on the basis of national and international guidelines for CVD prevention . We estimated the proportion of men and women who were similarly categorised as high risk or low risk by the two risk scores . FINDINGS Predicted risks for the same risk factor profile were generally lower in HICs than in LMICs , with the highest risks in countries in central and southeast Asia and eastern Europe , including China and Russia . In HICs , the proportion of people aged 40 - 64 years at high risk of CVD ranged from 1 % for South Korean women to 42 % for Czech men ( using a ≥10 % risk threshold ) , and in low-income countries ranged from 2 % in Ug and a ( men and women ) to 13 % in Iranian men ( using a ≥20 % risk threshold ) . More than 80 % of adults were similarly classified as low or high risk by the laboratory-based and office-based risk scores . However , the office-based model substantially underestimated the risk among patients with diabetes . INTERPRETATION Our risk charts provide risk assessment tools that are recalibrated for each country and make the estimation of CVD risk possible without using laboratory-based measurements . FUNDING National Institutes of Health Cardiovascular disease , and the incidence of sudden cardiac death ( SCD ) , will increase significantly in low- and middle-income countries ( LMIC ) . Thus , SCD threatens to become a global public health problem . We present a summary of the current research that has investigated the epidemiology of SCD in LMIC . Few studies of SCD in LMIC exist , and they are of variable method ological quality . Risk factors for SCD are described , taking into account recent global burden of disease and risk factor statistics . We describe 1 proposal for a community-based , prospect i ve , multiple- source methodology for SCD monitoring and surveillance that can be implemented in LMIC . Further research into the epidemiology of SCD in LMIC , using st and ardized methodology , would allow investigators and policy makers to determine the regions , communities , and individuals most at need for SCD prevention . Focusing on SCD and its prevention in LMIC should be a priority for the global health community Background . Low and middle income countries ( LMICs ) are facing an increase of the impact of mental health problems while confronted with limited re sources and limited access to mental health care , known as the ‘ mental health gap ’ . One strategy to reduce the mental health gap would be to utilize the internet to provide more widely-distributed and low cost mental health care . We undertook this systematic review to investigate the effectiveness and efficacy of online interventions in LMICs . Methods . We systematic ally search ed the data -bases PubMed , PsycINFO , JMIR , and additional sources . MeSH terms , Thesaurus , and free text keywords were used . We included all r and omized controlled trials ( RCTs ) of online interventions in LMICs . Results . We found only three articles reported results of RCTs on  online interventions for mental health conditions in LMICs , but none of these interventions was compared with an active control condition . Also , the mental health conditions were diverse across the three studies . Conclusions . There is a dearth of studies examining the effect of online interventions  in LMICs , so we can not draw a firm conclusion on its effectiveness . However , given the effectiveness of  online interventions in high income countries and sharp increase of internet access in LMICs , online interventions may offer a potential to help reduce the ‘ mental health gap ’ . More studies are urgently needed in LMICs BACKGROUND Physical activity has a protective effect against  cardiovascular disease ( CVD )  in high-income countries , where physical activity is mainly recreational , but it is not known if this is also observed in lower-income countries , where physical activity is mainly non-recreational . We examined whether different amounts and types of physical activity are associated with lower mortality and CVD  in countries at different economic levels . METHODS In this prospect i ve cohort study , we recruited participants from 17 countries ( Canada , Sweden , United Arab Emirates , Argentina , Brazil , Chile , Pol and , Turkey , Malaysia , South Africa , China , Colombia , Iran , Bangladesh , India , Pakistan , and Zimbabwe ) . Within each country , urban and rural areas in and around selected cities and towns were identified to reflect the geographical diversity . Within these communities , we invited individuals aged between 35 and 70 years who intended to live at their current address for at least another 4 years .  Total physical activity  was assessed using the  International Physical Activity Question naire ( IPQA ) . Participants with pre-existing CVD were excluded from the analyses . Mortality and CVD were recorded during a mean of 6·9 years of follow-up . Primary clinical outcomes during follow-up were mortality plus major CVD ( CVD mortality , incident myocardial infa rct ion , stroke , or heart failure ) , either as a composite or separately . The effects of physical activity on mortality and CVD were adjusted for sociodemographic factors and other risk factors taking into account household , community , and country clustering . FINDINGS Between Jan 1 , 2003 , and Dec 31 , 2010 , 168 916 participants were enrolled , of whom 141 945 completed the IPAQ . Analyses were limited to the 130 843 participants without pre-existing CVD . Compared with low physical activity ( < 600 metabolic equivalents [ MET ] × minutes per week or < 150 minutes per week of moderate intensity physical activity ) , moderate ( 600 - 3000 MET × minutes or 150 - 750 minutes per week ) and high physical activity ( > 3000 MET × minutes or > 750 minutes per week ) were associated with grade d reduction in mortality ( hazard ratio 0·80 , 95 % CI 0·74 - 0·87 and 0·65 , 0·60 - 0·71 ; p<0·0001 for trend ) , and major CVD ( 0·86 , 0·78 - 0·93 ; p<0·001 for trend  ) . Higher physical activity was associated with lower risk of CVD and mortality  in high-income , middle-income , and low-income countries . The adjusted population attributable fraction for not meeting the physical activity guidelines was 8·0 % for mortality and 4·6 % for major CVD , and for not meeting high physical activity was 13·0 % for mortality and 9·5 % for major CVD . Both recreational and non-recreational physical activity were associated with benefits . INTERPRETATION Higher recreational and non-recreational physical activity was associated with a lower risk of mortality and CVD events in individuals from low-income , middle-income , and high-income countries . Increasing physical activity is a simple , widely applicable , low cost global strategy that could reduce deaths and CVD in middle age . FUNDING Population Health Research Institute , the Canadian Institutes of Health Research , Heart and Stroke Foundation of Ontario , Ontario SPOR Support Unit , Ontario Ministry of Health and Long-Term Care , AstraZeneca , Sanofi-Aventis , Boehringer Ingelheim , Servier , GSK , Novartis , King Pharma , and national and local organisations in participating countries that are listed at the end of the Article Background Cluster r and omised trials ( CRTs ) are a key instrument to evaluate public health interventions , particularly in low- and middle-income countries ( LMICs ) . Fidelity assessment examines study processes to gauge whether an intervention was delivered as initially planned . Evaluation of implementation fidelity ( IF ) is required to establish whether the measured effects of a trial are due to the intervention itself and may be particularly important for CRTs of complex interventions . Current CRT reporting guidelines offer no guidance on IF assessment . We will systematic ally review the scientific literature to study current practice s concerning the assessment of IF in CRTs of public health interventions in LMICs . Methods We will include  CRTs of public health interventions in LMICs that planned or assessed IF in either the trial protocol or the main trial report ( or an associated document ) . Search strategies use Medical Subject Headings ( MESH ) and text words related to CRTs , developing countries , and public health interventions . The electronic data base search was developed first for MEDLINE and adapted for the following data bases : EMBASE , CINAHL , PubMed , and EMB Review s , to identify CRT reports in English , Spanish , or French published on or after January 1 , 2012 . To ensure availability of a study protocol , we will include CRTs reporting a registration number in the abstract . For each included study , we will compare planned versus reported assessment of IF , and consider the dimensions of IF studied , and data collection methods used to evaluate each dimension . Data will be synthesis ed using quantitative and narrative techniques . Risk of bias for individual studies will be assessed using the Cochrane Collaboration Risk of Bias Tool criteria and additional criteria related to CRT methods . We will investigate possible sources of heterogeneity by performing subgroup analysis . This review was not eligible for inclusion in the PROSPERO registry . Discussion Fidelity assessment may be a key tool for making studies more reliable , internally valid , and externally generalizable . This review will provide a portrait of current practice s related to the assessment of intervention fidelity in CRTs and offer suggestions for improvement . Results will be relevant to research ers , those who finance health interventions , and for decision-makers who seek the best evidence on public health interventions Background Violence during pregnancy is a global problem , associated with serious health risks for both the mother and baby . Evaluation of interventions targeted for reducing or controlling domestic violence ( DV ) is still in its infancy , and the majority of findings are primarily from high-income countries ( HICs ) . Therefore , there is an urgent need for generating evidence of DV interventions among pregnant women in low- and middle-income countries ( LMICs ) . Methods Preferred Reporting Items for Systematic Review s and Meta-Analyses ( PRISMA ) guidelines will be employed to structure the review . A comprehensive search will be carried out via electronic data bases including MEDLINE , CINAHL , Scopus , Embase , Web of Science , PsycINFO , and The Cochrane library . Gray literature will also be scrutinized for potential articles . An optimal search strategy has been developed following consultations with subject-matter experts and librarians . This search strategy will be adapted to the different data bases . Experimental studies evaluating DV interventions among pregnant women from LMICs will be included in the review . The review will only include literature written in English . Two review ers will independently screen and assess studies for inclusion in the review . A third author will resolve any discrepancies between the review ers . Risk of bias will be assessed based on the Cochrane risk of bias assessment tool , and overall quality of the evidence will be judged using Grading of Recommendations , Assessment , Development , and Evaluation ( GRADE ) criteria . Findings will be presented with the narrative synthesis , and if applicable , they will be further quantified using r and om-effects meta- analysis . Effect size , risk ratio for dichotomous variables , and st and ardized mean differences for continuous variables will be calculated for each outcome using Review Manager 5.3 . Discussion Systematic review s to evaluate the efficacy of interventions to address DV within the perinatal context have been limited . Hence , no one intervention has emerged as substantially effective towards addressing perinatal DV and associated health consequences . The evidence generated from this systematic review will inform research ers and policy makers about the effectiveness of existing DV interventions among pregnant women in LMICs and provide recommendations for future research in this area . This in turn will contribute towards violence prevention in LMICs . Systematic review registration PROSPERO IMPORTANCE Little is known about adoption of healthy lifestyle behaviors among individuals with a coronary heart disease ( CHD ) or stroke event in communities across a range of countries worldwide . OBJECTIVE To examine the prevalence of avoidance or cessation of smoking , eating a healthy diet  , and undertaking regular physical activities  by individuals with a CHD or stroke event . DESIGN , SETTING , AND PARTICIPANTS Prospect i ve Urban Rural Epidemiology ( PURE ) was a large , prospect i ve cohort study that used an epidemiological survey of 153,996 adults , aged 35 to 70 years , from 628 urban and rural communities in 3 high-income countries ( HIC ) , 7 upper-middle-income countries ( UMIC ) , 3 lower-middle-income countries ( LMIC ) , and 4 low-income countries ( LIC ) , who were enrolled between January 2003 and December 2009 . MAIN OUTCOME MEASURES Smoking status ( current , former , never ) , level of exercise ( low , < 600 metabolic equivalent task [MET]-min/wk ; moderate , 600 - 3000 MET-min/wk ; high , > 3000 MET-min/wk ) , and diet ( classified by the Food Frequency Question naire and defined using the Alternative Healthy Eating Index ) . RESULTS Among 7519 individuals with self-reported CHD ( past event : median , 5.0 [ interquartile range { IQR } , 2.0 - 10.0 ] years ago ) or stroke ( past event : median , 4.0 [ IQR , 2.0 - 8.0 ] years ago ) , 18.5 % ( 95 % CI , 17.6%-19.4 % ) continued to smoke ; only 35.1 % ( 95 % CI , 29.6%-41.0 % ) undertook high levels of work- or leisure-related physical activity , and 39.0 % ( 95 % CI , 30.0%-48.7 % ) had healthy diets ; 14.3 % ( 95 % CI , 11.7%-17.3 % ) did not undertake any of the 3 healthy lifestyle behaviors and 4.3 % ( 95 % CI , 3.1%-5.8 % ) had all 3 . Overall , 52.5 % ( 95 % CI , 50.7%-54.3 % ) quit smoking ( by income country classification : 74.9 % [ 95 % CI , 71.1%-78.6 % ] in HIC ; 56.5 % [ 95 % CI , 53.4%-58.6 % ] in UMIC ; 42.6 % [ 95 % CI , 39.6%-45.6 % ] in LMIC ; and 38.1 % [ 95 % CI , 33.1%-43.2 % ] in LIC ) . Levels of physical activity increased with increasing country income but this trend was not statistically significant . The lowest prevalence of eating healthy diets was in LIC ( 25.8 % ; 95 % CI , 13.0%-44.8 % ) compared with LMIC ( 43.2 % ; 95 % CI , 30.0%-57.4 % ) , UMIC ( 45.1 % , 95 % CI , 30.9%-60.1 % ) , and HIC ( 43.4 % , 95 % CI , 21.0%-68.7 % ) . CONCLUSION AND RELEVANCE Among a sample of patients with a CHD or stroke event from countries with varying income levels , the prevalence  of healthy lifestyle behaviors  was low , with even lower levels in poorer countries BACKGROUND There is a need to evaluate and implement cost-effective strategies to improve adherence to treatments in coronary heart disease . There are no studies from low- to middle income countries ( LMICs ) evaluating trained community health worker (CHW)-based interventions for the secondary prevention of coronary heart disease . METHODS We design ed a hospital-based , open r and omized trial of CHW-based interventions versus st and ard care .  Patients after an acute coronary syndrome ( ACS ) were r and omized to an intervention group ( a CHW-based intervention package , comprising education tools to enhance self-care and adherence , and regular follow-up by the CHW ) or to st and ard care for 12 months during which study outcomes were recorded . The CHWs were trained over a period of 6 months . The primary outcome measure was medication adherence . The secondary outcomes were differences in adherence to lifestyle modification , physiological parameters ( blood pressure [ BP ] , body weight , body mass index [ BMI ] , heart rate , lipids ) , and major adverse cardiovascular events . RESULTS We recruited 806 patients stabilized after an ACS from 14 hospitals in 13 Indian cities . The mean age was 56.4 ( ± 11.32 ) years , and 17.2 % were females . A high prevalence of risk factors such as hypertension ( 43.4 % ) , diabetes ( 31.9 % ) , tobacco consumption ( 35.4 % ) , and inadequate physical activity ( 70.5 % ) was documented . A little over half had ST-elevation myocardial infa rct ion ( 53.7 % ) , and 46.3 % had non-ST-elevation myocardial infa rct ion or unstable angina . CONCLUSION The CHW interventions and training for SPREAD have been developed and adapted for local use . The results and experience of this study will be important to counter the burden of cardiovascular diseases in low- to middle income countries BACKGROUND Autism spectrum disorder affects more than 5 million children in south Asia . Although early interventions have been used for the treatment of children in high-income countries , no substantive trials have been done of the interventions adapted for use in low-income and middle-income countries ( LMICs ) . We therefore assessed the feasibility and acceptability of the parent-mediated intervention for autism spectrum disorder in south Asia ( PASS ) in India and Pakistan . METHODS A single-blind r and omised trial of the comparison of 12 sessions of PASS ( plus treatment as usual ) with treatment as usual alone delivered by non-specialist health workers was done at two centres in Goa , India , and Rawalpindi , Pakistan . Children aged 2 - 9 years with autism spectrum disorder were r and omly assigned ( 1:1 ) by use of probabilistic minimisation , controlling for treatment centre ( Goa or Rawalpindi ) , age ( < 6 years or ≥6 years ) , and functional impairment ( Vinel and Adaptive Behaviour Scale Composite score < 65 or ≥65 ) . The primary outcome was quality of parent-child interaction on the Dyadic Communication Measure for Autism at 8 months . Analysis was by intention to treat . The study is registered with IS RCT N , number IS RCT N79675498 . FINDINGS From Jan 1 to July 30 , 2013 , 65 children were r and omly allocated , 32 to the PASS group ( 15 in Goa and 17 in Rawalpindi ) and 33 to the treatment-as-usual group ( 15 in Goa and 18 in Rawalpindi ) . 26 ( 81 % ) of 32 participants completed the intervention . After adjustment for minimisation factors and baseline outcome , the primary outcome showed a treatment effect in favour of PASS in parental synchrony ( adjusted mean difference 0·25 [ 95 % CI 0·14 to 0·36 ] ; effect size 1·61 [ 95 % CI 0·90 to 2·32 ] ) and initiation of communication by the child with the parent ( 0·15 [ 0·04 to 0·26 ] ; effect size 0·99 [ 0·29 to 1·68 ] ) , but time in mutual shared attention was reduced ( -0·16 [ -0·26 to -0·05 ] ; effect size -0·70 [ -1·16 to -0·23 ] ) . INTERPRETATION Our results show the feasibility of adapting and task-shifting an intervention used in a high-income context to LMICs . The findings also replicate the positive primary outcome treatment effects of a parent-mediated communication-focused intervention in the original UK Preschool Autism Communication Trial , with one negative effect not reported previously . FUNDING Autism Speaks , USA This paper describes the Common Elements Treatment Approach ( CETA ) for adults presenting with mood or anxiety problems developed specifically for use with lay counselors in low- and middle-income countries ( LMIC ) . Details of the intervention development , training , supervision , and decision-making process are presented . Case vignettes are used as examples throughout . Preliminary findings are presented on counselor/supervisor performance and client outcomes from practice cases completed prior to r and omized controlled trials ( RCT ) conducted at two sites for adult survivors of torture and /or systematic violence in ( a ) southern Iraq and ( b ) Thail and -Burma border . Data suggest that local supervisors and lay counselors with little prior mental health training or experience maintained fidelity to the model . The majority of pilot clients were retained in treatment , suggesting acceptability . Using the Reliable Change Index ( RCI ) for each individual we examined the number of clients above a minimal threshold ( z > 1.96 ) for each outcome . In Iraq 100 % of clients had RCIs above the threshold for depression and posttraumatic stress , and 81.8 % for impaired function . In Thail and , 81.3 % of clients had RCIs above minimum threshold for depression , 68.8 % for posttraumatic stress , and 37.5 % for impaired function . Implementation of CETA is discussed in relation to cultural issues within LMIC . These findings , combined with US-based evidence , suggest that a common elements approach warrants further development and testing as a means for addressing the treatment gap for mental health problems in LMIC Background Therapeutic hypothermia reduces death and disability after moderate or severe neonatal encephalopathy in high-income countries and is used as st and ard therapy in these setting s. However , the safety and efficacy of cooling therapy in low- and middle-income countries ( LMICs ) , where 99 % of the disease burden occurs , remains unclear . We will examine whether whole body cooling reduces death or neurodisability at 18–22 months after neonatal encephalopathy , in LMICs . Methods We will r and omly allocate 408 term or near-term babies ( aged ≤ 6 h ) with moderate or severe neonatal encephalopathy admitted to public sector neonatal units in LMIC countries ( India , Bangladesh or Sri Lanka ) , to either usual care alone or whole-body cooling with usual care . Babies allocated to the cooling arm will have core body temperature maintained at 33.5 ° C using a servo-controlled cooling device for 72 h , followed by re-warming at 0.5 ° C per hour . All babies will have detailed infection screening at the time of recruitment and 3 Telsa cerebral magnetic resonance imaging and spectroscopy at 1–2 weeks after birth . Our primary endpoint is death or moderate or severe disability at the age of 18 months . Discussion Upon completion , HELIX will be the largest cooling trial in neonatal encephalopathy and will provide a definitive answer regarding the safety and efficacy of cooling therapy for neonatal encephalopathy in LMICs . The trial will also provide important data about the influence of co-existent perinatal infection on the efficacy of hypothermic neuroprotection . Trial registration Clinical Trials.gov , NCT02387385 . Registered on 27 February 2015 OBJECTIVE Hypertension and other noncommunicable diseases represent a growing threat to low/middle-income countries ( LMICs ) . Mobile health technologies may improve noncommunicable disease outcomes , but LMICs lack re sources to provide these services . We evaluated the efficacy of a cloud computing model using automated self-management calls plus home blood pressure ( BP ) monitoring as a strategy for improving systolic BPs ( SBPs ) and other outcomes of hypertensive patients in two LMICs . SUBJECTS AND METHODS This was a r and omized trial with a 6-week follow-up . Participants with high SBPs ( ≥140 mm Hg if nondiabetic and ≥130 mm Hg if diabetic ) were enrolled from clinics in Honduras and Mexico . Intervention patients received weekly automated monitoring and behavior change telephone calls sent from a server in the United States , plus a home BP monitor . At baseline , control patients received BP results , hypertension information , and usual healthcare . The primary outcome , SBP , was examined for all patients in addition to a preplanned subgroup with low literacy or high hypertension information needs . Secondary outcomes included perceived health status and medication-related problems . RESULTS Of the 200 patients recruited , 181 ( 90 % ) completed follow-up , and 117 of 181 had low literacy or high hypertension information needs . The median annual income was $ 2,900 USD , and average educational attainment was 6.5 years . At follow-up intervention patients ' SBPs decreased 4.2 mm Hg relative to controls ( 95 % confidence interval -9.1 , 0.7 ; p=0.09 ) . In the subgroup with high information needs , intervention patients ' average SBPs decreased 8.8 mm Hg ( -14.2 , -3.4 , p=0.002 ) . Compared with controls , intervention patients at follow-up reported fewer depressive symptoms ( p=0.004 ) , fewer medication problems ( p<0.0001 ) , better general health ( p<0.0001 ) , and greater satisfaction with care ( p≤0.004 ) . CONCLUSIONS Automated telephone care management plus home BP monitors can improve outcomes for hypertensive patients in LMICs . A cloud computing model within regional telecommunication centers could make these services available in areas with limited infrastructure for patient-focused informatics support BACKGROUND Hypertension is the leading risk factor responsible for premature death worldwide , but its burden has shifted to low- and middle-income countries . Therefore , we studied hypertension and cardiovascular risk in the population of Suriname , a middle-income country with a predominantly urban population of African and Asian ancestry . METHODS A r and om sample of 1,800 noninstitutionalized men and women aged 18 - 70 years was selected to be interviewed at home and examined at the local hospital for cardiovascular risk factors , asymptomatic organ damage , and cardiovascular disease . RESULTS The 1,157 participants examined ( 37 % men ) were mainly of self-defined Asian ( 43 % ) or African ( 39 % ) ancestry , mean age 43 years ( SD 14 ) . The majority of the population ( 71 % ) had  hypertension or prehypertension  , respectively , 40 % and 31 % . Furthermore , 72 % was obese or overweight , while 63 % had diabetes or prediabetes . Only 1 % of the adult population had an optimal cardiovascular risk profile . Hypertension awareness , treatment , and control were respectively 68 % , 56 % , and 20 % . In line with this , 22 % of the adult population had asymptomatic organ damage , including increased arterial stiffness , left ventricular hypertrophy , microalbuminuria , or asymptomatic chronic kidney disease . CONCLUSIONS In this first extensive cardiovascular assessment in the general population of this middle-income Caribbean country , high prevalence of hypertension with inadequate levels of treatment and control was predominant . The findings emphasize the need for collaborative effort from national and international bodies to prioritize the implementation of affordable and sustainable public health programs that combat the escalating hypertension and cardiovascular risk factor burden Background The burden of cardiovascular diseases ( CVDs ) remains unclear in many regions of the world . Objectives The GBD ( Global Burden of Disease ) 2015 study integrated data on disease incidence , prevalence , and mortality to produce consistent , up-to- date estimates for cardiovascular burden . Methods CVD mortality was estimated from vital registration and verbal autopsy data . CVD prevalence was estimated using modeling software and data from health surveys , prospect i ve cohorts , health system administrative data , and registries . Years lived with disability ( YLD ) were estimated by multiplying prevalence by disability weights . Years of life lost ( YLL ) were estimated by multiplying age-specific CVD deaths by a reference life expectancy . A sociodemographic index ( SDI ) was created for each location based on income per capita , educational attainment , and fertility . Results In 2015 , there were an estimated 422.7 million cases of CVD ( 95 % uncertainty interval : 415.53 to 427.87 million cases ) and 17.92 million CVD deaths ( 95 % uncertainty interval : 17.59 to 18.28 million CVD deaths ) . Declines in the age-st and ardized CVD death rate occurred between 1990 and 2015 in all high-income and some middle-income countries . Ischemic heart disease was the leading cause of CVD health lost globally , as well as in each world region , followed by stroke . As SDI increased beyond 0.25 , the highest CVD mortality shifted from women to men . CVD mortality decreased sharply for both sexes in countries with an SDI > 0.75 . Conclusions CVDs remain a major cause of health loss for all regions of the world . Sociodemographic change over the past 25 years has been associated with dramatic declines in CVD in regions with very high SDI , but only a gradual decrease or no change in most regions . Future up date s of the GBD study can be used to guide policymakers who are focused on reducing the overall burden of noncommunicable disease and achieving specific global health targets for CVD Background A novel approach is explored for improving causal inference in observational studies by comparing cohorts from high-income with low- or middle-income countries ( LMIC ) , where confounding structures differ . This is applied to assessing causal effects of  breastfeeding  on child blood pressure ( BP ) , body mass index ( BMI ) and intelligence quotient ( IQ ) . Methods St and ardized approaches for assessing the confounding structure of breastfeeding by socio-economic position were applied to the British Avon Longitudinal Study of Parents and Children ( ALSPAC ) ( N ≃ 5000 ) and Brazilian Pelotas 1993 cohorts ( N ≃ 1000 ) . This was used to improve causal inference regarding associations of breastfeeding with child BP , BMI and IQ . Analyses were extended to include results from a meta- analysis of five LMICs ( N ≃ 10 000 ) and compared with a r and omized trial of breastfeeding promotion . Findings Although higher socio-economic position was strongly associated with breastfeeding in ALSPAC , there was little such patterning in Pelotas . In ALSPAC , breastfeeding was associated with lower BP , lower BMI and higher IQ , adjusted for confounders , but in the directions expected if due to socioeconomic patterning . In contrast , in Pelotas , breastfeeding was not strongly associated with BP or BMI but was associated with higher IQ . Differences in associations observed between ALSPAC and the LMIC meta- analysis were in line with those observed between ALSPAC and Pelotas , but with robust evidence of heterogeneity detected between ALSPAC and the LMIC meta- analysis associations . Trial data supported the conclusions inferred by the cross-cohort comparisons , which provided evidence for causal effects on IQ but not for BP or BMI . Conclusion While reported associations of breastfeeding with child BP and BMI are likely to reflect residual confounding , breastfeeding may have causal effects on IQ . Comparing associations between population s with differing confounding structures can be used to improve causal inference in observational studies Background Tobacco use kills half a million people every month , most in low – middle income countries ( LMICs ) . There is an urgent need to identify potentially low-cost , scalable tobacco cessation interventions for these countries . Objective To evaluate a brief community outreach intervention delivered by health workers to promote tobacco cessation in India . Design Cluster-r and omised controlled trial . Setting 32 low-income administrative blocks in Delhi , half government authorised ( ‘ resettlement colony ’ ) and half unauthorised ( ‘ J.J. cluster ’ ) communities . Participants 1213 adult tobacco users . Interventions Administrative blocks were computer r and omised in a 1:1 ratio , to the intervention ( 16 clusters ; n=611 ) or control treatment ( 16 clusters ; n=602 ) , delivered and assessed at individual level between 07/2012 and 11/2013 . The intervention was single session quit advice ( 15 min ) plus a single training session in yogic breathing exercises ; the control condition comprised very brief quit advice ( 1 min ) alone . Both were delivered via outreach , with contact made though household visits . Measurements The primary outcome was 6-month sustained abstinence from all tobacco , assessed 7 months post intervention delivery , biochemically verified with salivary cotinine . Results The smoking cessation rate was higher in the intervention group ( 2.6 % ( 16/611 ) ) than in the control group ( 0.5 % ( 3/602 ) ) ( relative risk=5.32 , 95 % CI 1.43 to 19.74 , p=0.013 ) . There was no interaction with type of tobacco use ( smoked vs smokeless ) . Results did not change material ly in adjusted analyses , controlling for participant characteristics . Conclusions A single session community outreach intervention can increase tobacco cessation in LMIC . The effect size , while small , could impact public health if scaled up with high coverage . Trial registration number IS RCT CN23362894 BACKGROUND WHO has targeted that medicines to prevent recurrent cardiovascular disease be available in 80 % of communities and used by 50 % of eligible individuals by 2025 . We have previously reported that use of these medicines is very low , but now aim to assess how such low use relates to their lack of availability or poor affordability . METHODS We analysed information about availability and costs of cardiovascular disease medicines ( aspirin , β blockers , angiotensin-converting enzyme inhibitors , and statins ) in pharmacies gathered from 596 communities in 18 countries participating in the Prospect i ve Urban Rural Epidemiology ( PURE ) study . Medicines were considered available if present at the pharmacy when surveyed , and affordable if their combined cost was less than 20 % of household capacity-to-pay . We compared results from high-income , upper middle-income , lower middle-income , and low-income countries . Data from India were presented separately given its large , generic pharmaceutical industry . FINDINGS Communities were recruited between Jan 1 , 2003 , and Dec 31 , 2013 . All four cardiovascular disease medicines were available in 61 ( 95 % ) of 64 urban and 27 ( 90 % ) of 30 rural communities in high-income countries , 53 ( 80 % ) of 66 urban and 43 ( 73 % ) of 59 rural communities in upper middle-income countries , 69 ( 62 % ) of 111 urban and 42 ( 37 % ) of 114 rural communities in lower middle-income countries , eight ( 25 % ) of 32 urban and one ( 3 % ) of 30 rural communities in low-income countries ( excluding India ) , and 34 ( 89 % ) of 38 urban and 42 ( 81 % ) of 52 rural communities in India . The four cardiovascular disease medicines were potentially unaffordable for 0·14 % of households in high-income countries ( 14 of 9934 households ) , 25 % of upper middle-income countries ( 6299 of 24,776 ) , 33 % of lower middle-income countries ( 13,253 of 40,023 ) , 60 % of low-income countries ( excluding India ; 1976 of 3312 ) , and 59 % households in India ( 9939 of 16,874 ) . In low-income and middle-income countries , patients with previous cardiovascular disease were less likely to use all four medicines if fewer than four were available ( odds ratio [ OR ] 0·16 , 95 % CI 0·04 - 0·57 ) . In communities in which all four medicines were available , patients were less likely to use medicines if the household potentially could not afford them ( 0·16 , 0·04 - 0·55 ) . INTERPRETATION Secondary prevention medicines are unavailable and unaffordable for a large proportion of communities and households in upper middle-income , lower middle-income , and low-income countries , which have very low use of these medicines . Improvements to the availability and affordability of key medicines is likely to enhance their use and help towards achieving WHO 's targets of 50 % use of key medicines by 2025 .

METHODS AND RESULTS We used a combination of cohort and r and omised controlled trial evidence to estimate the effectiveness of high-risk strategies , based on the identification of high-risk factors or high absolute risk , and strategies based on population -wide reductions in cholesterol and blood pressure . High-risk strategies were potentially effective but would need to be used widely to have a substantial effect on CVD in the population . Aggressive pharmacological treatment ( using statins , beta-blockers , ACE-inhibitors and aspirin ) in individuals with a 10-year Framingham event risk of > or=30 % ( 6 % of population ) would have reduced major CVD by at most 11 % . This figure increased to 34 % at a > or=20 % treatment threshold ( 26 % of population ) . In contrast , modest downwards shifts in the population distributions of serum total cholesterol and systolic blood pressure led to marked expected reductions in major CVD . Taking regression dilution bias into account , 10 % reductions in long-term mean blood cholesterol and blood pressure could have reduced major CVD by 45 % . CONCLUSIONS If high-risk strategies are to have a major impact on CVD in the population , they need to be more widely used than previously envisaged . Population -wide reduction of major risk factors is needed if CVD is to be substantially reduced Limited data exist regarding the management of patients with acute coronary syndrome ( ACS ) in high-income countries compared with low/middle-income countries . We aim ed to compare in-hospital trends of revascularization and prescription of medications  at discharge in patients with ACS from high-income ( Canada and United States ) and low/middle-income ( India , Iran , Pakistan , and Tunisia ) countries . Data from a double-blind , placebo-controlled , r and omized trial investigating the effect of bupropion on smoking cessation in patients after an enzyme-positive ACS was used for our study . A total of 392 patients , 265 and 127 from high-income and from low/middle-income countries , respectively , were enrolled . Patients from high-income countries were older , and were more likely to have diagnosed hypertension and dyslipidemia . During the index hospitalization , patients from high-income countries were more likely to be treated by  percutaneous coronary intervention  ( odds ratio [ OR ] 19.7 , 95 % confidence interval [ CI ] 10.5 to 37.0 ) . Patients with ST elevation myocardial infa rct ion from high-income countries were more often treated by  primary percutaneous coronary intervention  ( OR 16.3 , 95 % CI 6.3 to 42.3 ) in contrast with thrombolytic therapy ( OR 0.24 , 95 % CI 0.14 to 0.41 ) . Patients from high-income countries were also more likely to receive evidence -based medications at discharge ( OR 2.32 , 95 % CI 1.19 to 4.52 , a composite of aspirin , clopidogrel , and statin ) . In conclusion , patients with ACS in low/middle-income countries were less likely to be revascularized and to receive evidence -based medications at discharge . Further studies are needed to underst and the underutilization of procedures and evidence -based medications in low/middle-income countries BACKGROUND Although most cardiovascular disease occurs in low-income and middle-income countries , little is known about the use of effective secondary prevention medications in these communities . We aim ed to assess use of proven effective secondary preventive drugs ( antiplatelet drugs , β blockers , angiotensin-converting-enzyme [ ACE ] inhibitors or angiotensin-receptor blockers [ ARBs ] , and statins ) in individuals with a history of coronary heart disease or stroke . METHODS In the Prospect i ve Urban Rural Epidemiological ( PURE ) study , we recruited individuals aged 35 - 70 years from rural and urban communities in countries at various stages of economic development . We assessed rates of previous cardiovascular disease ( coronary heart disease or stroke ) and use of proven effective  secondary preventive drugs  and blood-pressure-lowering drugs with st and ardised question naires , which were completed by telephone interviews , household visits , or on patient 's presentation to clinics . We report estimates of drug use at national , community , and individual levels . FINDINGS We enrolled 153,996 adults from 628 urban and rural communities in countries with incomes classified as high ( three countries ) , upper-middle ( seven ) , lower-middle ( three ) , or low ( four ) between January , 2003 , and December , 2009 . 5650 participants had a self-reported coronary heart disease event ( median 5·0 years previously [ IQR 2·0 - 10·0 ] ) and 2292 had stroke ( 4·0 years previously [ 2·0 - 8·0 ] ) . Overall , few individuals with cardiovascular disease took antiplatelet drugs  ( 25·3 % ) , β blockers ( 17·4 % ) , ACE inhibitors or ARBs ( 19·5 % ) , or statins ( 14·6 % ) . Use was highest in high-income countries ( antiplatelet drugs 62·0 % , β blockers 40·0 % , ACE inhibitors or ARBs 49·8 % , and statins 66·5 % ) , lowest in low-income countries ( 8·8 % , 9·7 % , 5·2 % , and 3·3 % , respectively ) , and decreased in line with reduction of country economic status ( p(trend)<0·0001 for every drug type ) . Fewest patients received no drugs in high-income countries ( 11·2 % ) , compared with 45·1 % in upper middle-income countries , 69·3 % in lower middle-income countries , and 80·2 % in low-income countries . Drug use was higher in urban than rural areas ( antiplatelet drugs 28·7 % urban vs 21·3 % rural , β blockers 23·5%vs 15·6 % , ACE inhibitors or ARBs 22·8%vs 15·5 % , and statins 19·9%vs 11·6 % ; all p<0·0001 ) , with greatest variation in poorest countries ( p(interaction)<0·0001 for urban vs rural differences by country economic status ) . Country-level factors ( eg , economic status ) affected rates of drug use more than did individual-level factors ( eg , age , sex , education , smoking status , body-mass index , and hypertension and diabetes statuses ) . INTERPRETATION Because use of secondary prevention medications is low worldwide-especially in low-income countries and rural areas - systematic approaches are needed to improve the long-term use of basic , inexpensive , and effective drugs . FUNDING Full funding sources listed at end of paper ( see Acknowledgments ) Introduction Task shifting interventions are intended to both deliver clinical ly effective treatments to reduce disease burden and address health inequities or population vulnerability . Little is known about how health equity and population vulnerability are defined and measured in research focused on task shifting . This systematic review will address the following questions : Among  task shifting interventions in high-income setting s that have been studied using r and omised controlled trials or variants , how are health inequity or population vulnerability identified and defined ? What methods and indicators are used to describe , characterise and measure the population ’s baseline status and the intervention ’s impacts on inequity and vulnerability ? Methods and analysis Studies were identified through data base search es ( MEDLINE , Embase , CINAHL , PsycINFO and Web of Science ) . Eligible studies will be r and omised controlled trials published since 2004 , conducted in high-income countries , concerning task shifting interventions to treat any disease , in any population that may face health disadvantage as defined by the PROGRESS-Plus framework ( place of residence , race/ethnicity/culture/ language , occupation , gender/sex , religion , social capital , socioeconomic position , age , disability , sexual orientation , other vulnerable groups ) . We will conduct independent and duplicate title and abstract screening , then identify related papers from the same programme of research through further data base and manual search ing . From each programme of research , we will extract study details , and definitions and measures of health equity or population vulnerability based on the PROGRESS-Plus framework . Two investigators will assess the quality of reporting and measurement related to health equity and vulnerability using a scale developed for this study . A narrative synthesis will highlight similarities and differences between the gathered studies and offer critical analyses and implication s. Ethics and dissemination This review does not involve primary data collection , does not constitute research on human subjects and is not subject to additional institutional ethics review or informed consent procedures . Dissemination will include open-access peer- review ed publication and academic conference presentations . PROSPERO Registration Number CRD42017049959 IMPORTANCE Hypertension is the most important preventable cause of morbidity and mortality globally , yet there are relatively few data collected using st and ardized methods . OBJECTIVE To examine hypertension prevalence , awareness , treatment , and control in participants at baseline in the Prospect i ve Urban Rural Epidemiology ( PURE ) study . DESIGN , SETTING , AND PARTICIPANTS A cross-sectional study of 153,996 adults ( complete data for this analysis on 142,042 ) aged 35 to 70 years , recruited between January 2003 and December 2009 . Participants were from 628 communities in 3 high-income countries ( HIC ) , 10 upper-middle-income and low-middle-income countries ( UMIC and LMIC ) , and 4 low-income countries ( LIC ) . MAIN OUTCOMES AND MEASURES Hypertension was defined as individuals with self-reported treated hypertension  or with an average of 2 blood pressure measurements of at least 140/90 mm Hg using an automated digital device . Awareness was based on self-reports , treatment was based on the regular use of blood pressure-lowering medications , and control was defined as individuals with blood pressure lower than 140/90 mm Hg . RESULTS Among the 142,042 participants , 57,840 ( 40.8 % ; 95 % CI , 40.5%-41.0 % ) had hypertension and 26,877 ( 46.5 % ; 95 % CI , 46.1%-46.9 % ) were aware of the diagnosis . Of those who were aware of the diagnosis , the majority ( 23,510 [ 87.5 % ; 95 % CI , 87.1%-87.9 % ] of those who were aware ) were receiving pharmacological treatments , but only a minority of those receiving treatment were controlled ( 7634 [ 32.5 % ; 95 % CI , 31.9%-33.1 % ] ) . Overall , 30.8 % , 95 % CI , 30.2%-31.4 % of treated patients were taking 2 or more types of blood pressure-lowering medications . The percentages aware ( 49.0 % [ 95 % CI , 47.8%-50.3 % ] in HICs , 52.5 % [ 95 % CI , 51.8%-53.2 % ] in UMICs , 43.6 % [ 95 % CI , 42.9%-44.2 % ] in LMICs , and 40.8 % [ 95 % CI , 39.9%-41.8 % ] in LICs ) and treated ( 46.7 % [ 95 % CI , 45.5%-47.9 % ] in HICs , 48.3 % , [ 95 % CI , 47.6%-49.1 % ] in UMICs , 36.9 % , [ 95 % CI , 36.3%-37.6 % ] in LMICs , and 31.7 % [ 95 % CI , 30.8%-32.6 % ] in LICs ) were lower in LICs compared with all other countries for awareness ( P < .001 ) and treatment ( P < .001 ) . Awareness , treatment , and control of hypertension were higher in urban communities compared with rural ones in LICs ( urban vs rural , P < .001 ) and LMICs ( urban vs rural , P < .001 ) , but similar for other countries . Low education was associated with lower rates of awareness , treatment , and control in LICs , but not in other countries . CONCLUSIONS AND RELEVANCE Among a multinational study population , 46.5 % of participants with hypertension were aware of the diagnosis , with blood pressure control among 32.5 % of those being treated . These findings suggest substantial room for improvement in hypertension diagnosis and treatment
Conclusions There is a dearth of evidence on the implementation of task-shifting strategies to reduce the burden of CVD in LMICs .
Objective To evaluate evidence from published r and omised controlled trials ( RCTs ) for the use of task-shifting strategies for cardiovascular disease ( CVD ) risk  reduction in low-income and middle-income countries ( LMICs ) .
