Nutrients 2024; 16:1999. [PMID: 38999748 PMCID: PMC11243307 DOI: 10.3390/nu16131999] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/30/2024] [Revised: 06/04/2024] [Accepted: 06/20/2024] [Indexed: 07/14/2024] Open
Abstract
There is a rising prevalence of non-communicable diseases (NCDs) in Papua New Guinea (PNG), adding to the disease burden from communicable infectious diseases and thus increasing the burden on the healthcare system in a low-resource setting. The aim of this review was to identify health and nutrition promotion programs conducted in PNG and the enablers and barriers to these programs. Four electronic databases and grey literature were searched. Two reviewers completed screening and data extraction. This review included 23 papers evaluating 22 health and nutrition promotion programs, which focused on the Ottawa Charter action areas of developing personal skills (12 programs), reorienting health services (12 programs) and strengthening community action (6 programs). Nineteen programs targeted communicable diseases; two addressed NCDs, and one addressed health services. Enablers of health promotion programs in PNG included community involvement, cultural appropriateness, strong leadership, and the use of mobile health technologies for the decentralisation of health services. Barriers included limited resources and funding and a lack of central leadership to drive ongoing implementation. There is an urgent need for health and nutrition promotion programs targeting NCDs and their modifiable risk factors, as well as longitudinal study designs for the evaluation of long-term impact and program sustainability.

The effect of nutrition-specific and nutrition-sensitive interventions on the double burden of malnutrition in low-income and middle-income countries: a systematic review. Lancet Glob Health 2024; 12:e419-e432. [PMID: 38301666 PMCID: PMC7616050 DOI: 10.1016/s2214-109x(23)00562-4] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/22/2023] [Revised: 11/27/2023] [Accepted: 11/28/2023] [Indexed: 02/03/2024]
Abstract
BACKGROUND Low-income and middle-income countries (LMICs) experiencing nutrition transition face an increasing double burden of malnutrition (DBM). WHO has urged the identification of risks and opportunities in nutrition interventions to mitigate the DBM, but robust evidence is missing. This review summarises the effect of nutrition-specific and nutrition-sensitive interventions on undernutrition and overnutrition in LMICs. METHODS We searched four major databases and grey literature for publications in English, French, Portuguese, and Spanish from Jan 1, 2000, to Aug 14, 2023. Eligible studies evaluated nutrition-specific or nutrition-sensitive interventions on both undernutrition and overnutrition, employing robust study designs (individually randomised, cluster randomised, and non-randomised trials; interrupted time series; controlled before-after; and prospective cohort studies). Studies were synthesised narratively, and classified as DBM-beneficial, potentially DBM-beneficial, DBM-neutral, potentially DBM-harmful, and DBM-harmful, using vote counting. This review is registered with PROSPERO (CRD42022320131). FINDINGS We identified 26 studies evaluating 20 nutrition-specific (maternal and child health [MCH] and school-based programmes) and six nutrition-sensitive (conditional cash transfers and other social policies) interventions. Seven of eight MCH interventions providing food-based or nutritional supplements indicated possible DBM-harmful effects, associated with increased maternal or child overweight. Most school-based programmes and MCH interventions that target behavioural change were considered potentially DBM-beneficial. Two studies of conditional cash transfers suggested DBM-beneficial effects in children, whereas one indicated potentially harmful effects on maternal overweight. A study on a family planning service and one on an education reform revealed possible long-term harmful effects on obesity. INTERPRETATION There is considerable scope to repurpose existing nutrition interventions to reduce the growing burden of the DBM in LMICs. In settings undergoing rapid nutrition transition, specific policy attention is required to ensure that food-based or supplement-based MCH programmes do not unintentionally increase maternal or child overweight. Consistent reporting of undernutrition and overnutrition outcomes in all nutrition interventions is essential to expand the evidence base to identify and promote interventions maximising benefits and minimising harms on the DBM.

Abstract
OBJECTIVE To identify and describe (1) which health-related quality of life (HRQoL) measures have been used with Indigenous children/youth (aged 8-17 years) within the Pacific Rim; and (2) studies that refer to Indigenous health concepts in the use of child/youth HRQoL measures. DESIGN A scoping review. DATA SOURCES Ovid (Medline), PubMed, Scopus, Web of Science and CINAHL were searched up until 25 June 2020. ELIGIBILITY CRITERIA Eligible papers were identified by two independent reviewers. Eligible papers were written in English, published between January 1990 and June 2020 and included an HRQoL measure used in research with Indigenous child/youth populations (aged between 8 and 17 years) in the Pacific Rim region. DATA EXTRACTION AND SYNTHESIS Data extracted included study characteristics (year, country, Indigenous population, Indigenous sample size, age group), HRQoL measure characteristics (generic or condition-specific measure, child or adult measure, who completed the measure(s), dimensions, items and response scale of measure) and consideration of Indigenous concepts (created for Indigenous population, modified for Indigenous population, validated for Indigenous population, reliability in Indigenous populations, Indigenous involvement, reference to Indigenous theories/models/frameworks). RESULTS After removing duplicates, 1393 paper titles and abstracts were screened, and 543 had full-text review for eligibility. Of these, 40 full-text papers were eligible, reporting on 32 unique studies. Twenty-nine HRQoL measures were used across eight countries. Thirty-three papers did not acknowledge Indigenous concepts of health, and only two measures were specifically created for use with Indigenous populations. CONCLUSIONS There is a paucity of research investigating HRQoL measures used with Indigenous children/youth and a lack of involvement of Indigenous peoples in the development and use of HRQoL measures. We strongly recommend explicit consideration of Indigenous concepts when developing, validating, assessing and using HRQoL measures with Indigenous populations.

Abstract
Small island developing states (SIDS) have a high burden of nutrition-related disease associated with nutrient-poor, energy-dense diets. In response to these issues, we assessed the effectiveness of nutrition-based interventions on nutritional status (under-nutrition) and metabolic health (over-nutrition) among persons in SIDS. We included SIDS-based nutrition studies with change in nutrition status (e.g., markers of anaemia) or metabolic status (e.g., markers of glycaemia) as outcomes. The PRISMA framework was applied and MEDLINE, Embase, CINAHL, OARE library, Web of Science, Scopus, ASSIA, EconLit, AGORA, AGRICOLA, AGRIS, WHO-EMRO, and LILACS were searched (2000−2020). Cochrane risk of bias (ROB) and Cochrane ROBINS-I tools assessed ROB for randomised and non-randomised studies, respectively. PROSPERO registration (CRD42021236396) was undertaken. We included 50 eligible interventions, involving 37,591 participants: 14 trials reported on nutritional status, 36 on metabolic health. Effective interventions, evaluated at the individual level, took a multifaceted approach for metabolic outcomes; while nutrition outcomes utilised supplements. Most intervention types were suitable for issues related to ‘over’ nutrition versus ‘under’ nutrition. Twenty-six studies (nutrition status (six); metabolic health (twenty)) were effective (p < 0.05). With the current rise of nutrition-related public health challenges, there is a need for further development and evaluation of these and related interventions at the population level.

A scoping review of whole-of-community interventions on six modifiable cancer prevention risk factors in youth: A systems typology. Prev Med 2021; 153:106769. [PMID: 34416222 DOI: 10.1016/j.ypmed.2021.106769] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/12/2021] [Revised: 06/09/2021] [Accepted: 08/15/2021] [Indexed: 12/28/2022]
Abstract
Whole-of-community interventions delivered across entire geospatial areas show promise for improving population health for youth cancer prevention. The aims of this scoping review were to synthesize the whole-of-community intervention literature on six modifiable risk factors in youth for cancer prevention (alcohol use, diet, obesity, physical activity, sun exposure, tobacco use) and to develop and apply a typology describing the inclusion of fundamental control system functional characteristics. A systematic search was conducted in PubMed, Cumulative Index to Nursing and Allied Health Literature, Embase, PsycINFO, and Scopus for studies published to the end of 2019. Eligible studies included a geospatially defined whole-of-community intervention; youth 0-18 years; and at least one of the six cancer risk factor outcomes. An iterative process was undertaken to create a typology describing the functions for whole-of-community interventions guided by systems theory, and the typology was used to code the included interventions. A total of 41 interventions were included. Most interventions (43.9%) assessed multiple cancer risk factors. Few interventions provided fundamental functions necessary for community system coordination: sensor, controller, effector. Although communities are a patchwork quilt of microsystems where individuals interact in geographically bounded places nested within larger whole systems of influence, a control systems approach has not been used to frame the literature. Whole-of-community interventions can be characterized by the fundamental system functions necessary for coordinating population health improvement. Future whole-of-community intervention efforts should draw on fundamental knowledge of how systems operate and test whether adoption of the key functions is necessary for whole-of-community population health improvement.

Abstract
BACKGROUND Physical activity among children and adolescents is associated with lower adiposity, improved cardio-metabolic health, and improved fitness. Worldwide, fewer than 30% of children and adolescents meet global physical activity recommendations of at least 60 minutes of moderate to vigorous physical activity per day. Schools may be ideal sites for interventions given that children and adolescents in most parts of the world spend a substantial amount of time in transit to and from school or attending school. OBJECTIVES The purpose of this review update is to summarise the evidence on effectiveness of school-based interventions in increasing moderate to vigorous physical activity and improving fitness among children and adolescents 6 to 18 years of age. Specific objectives are: • to evaluate the effects of school-based interventions on increasing physical activity and improving fitness among children and adolescents; • to evaluate the effects of school-based interventions on improving body composition; and • to determine whether certain combinations or components (or both) of school-based interventions are more effective than others in promoting physical activity and fitness in this target population. SEARCH METHODS We searched CENTRAL, MEDLINE, Embase, CINAHL, PsycINFO, BIOSIS, SPORTDiscus, and Sociological Abstracts to 1 June 2020, without language restrictions. We screened reference lists of included articles and relevant systematic reviews. We contacted primary authors of studies to ask for additional information. SELECTION CRITERIA Eligible interventions were relevant to public health practice (i.e. were not delivered by a clinician), were implemented in the school setting, and aimed to increase physical activity among all school-attending children and adolescents (aged 6 to 18) for at least 12 weeks. The review was limited to randomised controlled trials. For this update, we have added two new criteria: the primary aim of the study was to increase physical activity or fitness, and the study used an objective measure of physical activity or fitness. Primary outcomes included proportion of participants meeting physical activity guidelines and duration of moderate to vigorous physical activity and sedentary time (new to this update). Secondary outcomes included measured body mass index (BMI), physical fitness, health-related quality of life (new to this update), and adverse events (new to this update). Television viewing time, blood cholesterol, and blood pressure have been removed from this update. DATA COLLECTION AND ANALYSIS: Two independent review authors used standardised forms to assess each study for relevance, to extract data, and to assess risk of bias. When discrepancies existed, discussion occurred until consensus was reached. Certainty of evidence was assessed according to GRADE. A random-effects meta-analysis based on the inverse variance method was conducted with participants stratified by age (children versus adolescents) when sufficient data were reported. Subgroup analyses explored effects by intervention type. MAIN RESULTS Based on the three new inclusion criteria, we excluded 16 of the 44 studies included in the previous version of this review. We screened an additional 9968 titles (search October 2011 to June 2020), of which 978 unique studies were potentially relevant and 61 met all criteria for this update. We included a total of 89 studies representing complete data for 66,752 study participants. Most studies included children only (n = 56), followed by adolescents only (n = 22), and both (n = 10); one study did not report student age. Multi-component interventions were most common (n = 40), followed by schooltime physical activity (n = 19), enhanced physical education (n = 15), and before and after school programmes (n = 14); one study explored both enhanced physical education and an after school programme. Lack of blinding of participants, personnel, and outcome assessors and loss to follow-up were the most common sources of bias. Results show that school-based physical activity interventions probably result in little to no increase in time engaged in moderate to vigorous physical activity (mean difference (MD) 0.73 minutes/d, 95% confidence interval (CI) 0.16 to 1.30; 33 studies; moderate-certainty evidence) and may lead to little to no decrease in sedentary time (MD -3.78 minutes/d, 95% CI -7.80 to 0.24; 16 studies; low-certainty evidence). School-based physical activity interventions may improve physical fitness reported as maximal oxygen uptake (VO₂max) (MD 1.19 mL/kg/min, 95% CI 0.57 to 1.82; 13 studies; low-certainty evidence). School-based physical activity interventions may result in a very small decrease in BMI z-scores (MD -0.06, 95% CI -0.09 to -0.02; 21 studies; low-certainty evidence) and may not impact BMI expressed as kg/m² (MD -0.07, 95% CI -0.15 to 0.01; 50 studies; low-certainty evidence). We are very uncertain whether school-based physical activity interventions impact health-related quality of life or adverse events. AUTHORS' CONCLUSIONS Given the variability of results and the overall small effects, school staff and public health professionals must give the matter considerable thought before implementing school-based physical activity interventions. Given the heterogeneity of effects, the risk of bias, and findings that the magnitude of effect is generally small, results should be interpreted cautiously.

Abstract
BACKGROUND Childhood obesity persists as a serious public health problem. In the current meta-analysis, we summarized the results of controlled trials that evaluated the effect of obesity prevention policies in children and adolescents. METHODS Three databases (SCOPUS, PubMed and Embase) were searched for studies published before the 6th April 2020, by reported outcome measures of body mass index (BMI) and BMI-Zscore. Forty-seven studies reported BMI, while 45 studies reported BMI-Zscore as final outcome. RESULTS The results showed that the obesity-prevention policies had significant effect in reducing BMI (WMD: - 0.127; CI - 0.198, - 0.056; P < 0.001). These changes were not significant for BMI-Zscore (WMD: - 0.020; CI - 0.061, 0.021; P = 0.340). In dose-response meta-analysis, a non-linear association was reported between the duration of intervention and BMI (Pnonlinearity < 0.001) as well as BMI-Zscore (Pnonlinearity = 0.023). In subgroup analysis, the more favorite results were observed for 5-10 years old, with combination of physical activity and diet as intervention materials. CONCLUSION In conclusion, the obesity prevention policies in short-term periods of less than 2 years, in rather early age of school with approaches of change in both of diet and physical activity, could be more effective in prevention of childhood obesity.

Effect of Food Environment Interventions on Anthropometric Outcomes in School-Aged Children and Adolescents in Low- and Middle-Income Countries: A Systematic Review and Meta-Analysis. Curr Dev Nutr 2020; 4:nzaa098. [PMID: 32666031 PMCID: PMC7340483 DOI: 10.1093/cdn/nzaa098] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/15/2020] [Revised: 04/29/2020] [Accepted: 05/21/2020] [Indexed: 12/28/2022] Open
Abstract
Food environments may promote access to unhealthy foods, contributing to noncommunicable diseases in low- and middle- income countries (LMICs). This review assessed published evidence on the effects of food environment interventions on anthropometric (BMI and weight status) outcomes in school-aged children (5-9 y) and adolescents (10-19 y) (SACA) in LMICs. We summarized randomized controlled trials (RCTs) and quasi-experimental studies (QES) published since 2000 to August 2019 in the peer-reviewed and gray literature that assessed the effects of food-related behavioral and environmental interventions on diet-related health outcomes in SACA in LMICs. Electronic databases (MEDLINE, Embase, PsycINFO, Cochrane Library) were searched using appropriate keywords, Medical Subject Headings, and free text terms. Eleven RCTs and 6 QES met the inclusion criteria, testing multicomponent behavioral and environmental interventions in schools. Analysis of 6 RCTs (n = 17,054) suggested an overall effect on change in BMI [mean difference (MD): -0.11, 95% CI: -0.19 , -0.03], whereas there was no observed effect in 5 studies using endline BMI (n = 17,371) (MD: 0.05, 95% CI: -0.32, 0.21). There was no significant pooled effect among the 3 QES (n = 5,023) that reported differences in change in BMI or endline (MD: -0.37, 95% CI: -0.95, 0.22). There is limited evidence to support the modification of diet-related health outcomes through school-based food environment interventions in SACA in LMICs. Further studies are needed to understand the impact of school and community-based food environment interventions on nutritional status in this population.

Abstract
EDITORIAL NOTE This Cochrane review is now out of date and should not be used for reference. It has been split into four age groups and updated. Please refer to the 5‐11 and 12‐18 age group Cochrane reviews which were published in May 2024: https://doi.org/10.1002/14651858.CD015328.pub2 https://doi.org/10.1002/14651858.CD015330.pub2 The 2‐4 age group Cochrane review is planned for publication in September 2024. BACKGROUND Prevention of childhood obesity is an international public health priority given the significant impact of obesity on acute and chronic diseases, general health, development and well-being. The international evidence base for strategies to prevent obesity is very large and is accumulating rapidly. This is an update of a previous review. OBJECTIVES To determine the effectiveness of a range of interventions that include diet or physical activity components, or both, designed to prevent obesity in children. SEARCH METHODS We searched CENTRAL, MEDLINE, Embase, PsychINFO and CINAHL in June 2015. We re-ran the search from June 2015 to January 2018 and included a search of trial registers. SELECTION CRITERIA Randomised controlled trials (RCTs) of diet or physical activity interventions, or combined diet and physical activity interventions, for preventing overweight or obesity in children (0-17 years) that reported outcomes at a minimum of 12 weeks from baseline. DATA COLLECTION AND ANALYSIS Two authors independently extracted data, assessed risk-of-bias and evaluated overall certainty of the evidence using GRADE. We extracted data on adiposity outcomes, sociodemographic characteristics, adverse events, intervention process and costs. We meta-analysed data as guided by the Cochrane Handbook for Systematic Reviews of Interventions and presented separate meta-analyses by age group for child 0 to 5 years, 6 to 12 years, and 13 to 18 years for zBMI and BMI. MAIN RESULTS We included 153 RCTs, mostly from the USA or Europe. Thirteen studies were based in upper-middle-income countries (UMIC: Brazil, Ecuador, Lebanon, Mexico, Thailand, Turkey, US-Mexico border), and one was based in a lower middle-income country (LMIC: Egypt). The majority (85) targeted children aged 6 to 12 years.Children aged 0-5 years: There is moderate-certainty evidence from 16 RCTs (n = 6261) that diet combined with physical activity interventions, compared with control, reduced BMI (mean difference (MD) -0.07 kg/m2, 95% confidence interval (CI) -0.14 to -0.01), and had a similar effect (11 RCTs, n = 5536) on zBMI (MD -0.11, 95% CI -0.21 to 0.01). Neither diet (moderate-certainty evidence) nor physical activity interventions alone (high-certainty evidence) compared with control reduced BMI (physical activity alone: MD -0.22 kg/m2, 95% CI -0.44 to 0.01) or zBMI (diet alone: MD -0.14, 95% CI -0.32 to 0.04; physical activity alone: MD 0.01, 95% CI -0.10 to 0.13) in children aged 0-5 years.Children aged 6 to 12 years: There is moderate-certainty evidence from 14 RCTs (n = 16,410) that physical activity interventions, compared with control, reduced BMI (MD -0.10 kg/m2, 95% CI -0.14 to -0.05). However, there is moderate-certainty evidence that they had little or no effect on zBMI (MD -0.02, 95% CI -0.06 to 0.02). There is low-certainty evidence from 20 RCTs (n = 24,043) that diet combined with physical activity interventions, compared with control, reduced zBMI (MD -0.05 kg/m2, 95% CI -0.10 to -0.01). There is high-certainty evidence that diet interventions, compared with control, had little impact on zBMI (MD -0.03, 95% CI -0.06 to 0.01) or BMI (-0.02 kg/m2, 95% CI -0.11 to 0.06).Children aged 13 to 18 years: There is very low-certainty evidence that physical activity interventions, compared with control reduced BMI (MD -1.53 kg/m2, 95% CI -2.67 to -0.39; 4 RCTs; n = 720); and low-certainty evidence for a reduction in zBMI (MD -0.2, 95% CI -0.3 to -0.1; 1 RCT; n = 100). There is low-certainty evidence from eight RCTs (n = 16,583) that diet combined with physical activity interventions, compared with control, had no effect on BMI (MD -0.02 kg/m2, 95% CI -0.10 to 0.05); or zBMI (MD 0.01, 95% CI -0.05 to 0.07; 6 RCTs; n = 16,543). Evidence from two RCTs (low-certainty evidence; n = 294) found no effect of diet interventions on BMI.Direct comparisons of interventions: Two RCTs reported data directly comparing diet with either physical activity or diet combined with physical activity interventions for children aged 6 to 12 years and reported no differences.Heterogeneity was apparent in the results from all three age groups, which could not be entirely explained by setting or duration of the interventions. Where reported, interventions did not appear to result in adverse effects (16 RCTs) or increase health inequalities (gender: 30 RCTs; socioeconomic status: 18 RCTs), although relatively few studies examined these factors.Re-running the searches in January 2018 identified 315 records with potential relevance to this review, which will be synthesised in the next update. AUTHORS' CONCLUSIONS Interventions that include diet combined with physical activity interventions can reduce the risk of obesity (zBMI and BMI) in young children aged 0 to 5 years. There is weaker evidence from a single study that dietary interventions may be beneficial.However, interventions that focus only on physical activity do not appear to be effective in children of this age. In contrast, interventions that only focus on physical activity can reduce the risk of obesity (BMI) in children aged 6 to 12 years, and adolescents aged 13 to 18 years. In these age groups, there is no evidence that interventions that only focus on diet are effective, and some evidence that diet combined with physical activity interventions may be effective. Importantly, this updated review also suggests that interventions to prevent childhood obesity do not appear to result in adverse effects or health inequalities.The review will not be updated in its current form. To manage the growth in RCTs of child obesity prevention interventions, in future, this review will be split into three separate reviews based on child age.

Efficacy of population-wide diabetes and obesity prevention programs: An overview of systematic reviews on proximal, intermediate, and distal outcomes and a meta-analysis of impact on BMI.

Abstract
We conducted an overview of systematic reviews and a meta-analysis of the impact on body mass index (BMI) of primary studies of population-wide obesity and diabetes prevention programs, in order to evaluate their efficacy. We searched eight databases for reviews of population-level programs reporting effect on diet, physical activity, BMI, or prevalence of obesity/overweight or type 2 diabetes mellitus (T2DM). Meta-analysis of primary studies within reviews reporting effect on BMI. Interventions were categorized using ANGELO framework and quality assessment using AMSTAR. Fifty-three systematic reviews were included. Primary studies were largely natural experiments or cross-sectional studies of national data. Increased price of sugar-sweetened beverages (SSBs) and fast food, decreased price of fruit and vegetables, food labelling, and grocery store interventions were associated with positive effects on diet. Park and playground renovations and point-of-choice prompts to increase stair use were associated with positive effects on physical activity. Increased price of SSBs, menu labelling, grocery store interventions, and multicomponent interventions were associated with small reductions in BMI. There was insufficient evidence of impact of any interventions on the prevalence of overweight, obesity, or T2DM. We have identified a promising suite of population-wide actions to improve diet, increase physical activity, and reduce BMI. Impact on subsequent incidence of T2DM remains speculative.

Cost-effectiveness of community-based childhood obesity prevention interventions in Australia. Int J Obes (Lond) 2019; 43:1102-1112. [PMID: 30926947 DOI: 10.1038/s41366-019-0341-0] [Citation(s) in RCA: 27] [Impact Index Per Article: 5.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/26/2018] [Revised: 01/13/2019] [Accepted: 03/03/2019] [Indexed: 01/08/2023]
Abstract
OBJECTIVES The objective of this study is to examine, from a limited societal perspective, the cost-effectiveness of community-based obesity prevention interventions (CBIs)-defined as a programme of community-level strategies to promote healthy eating and physical activity for Australian children (aged 5-18 years). METHODS The effectiveness of CBIs was determined by undertaking a literature review and meta-analysis. Commonly implemented strategies to increase physical activity and improve nutrition were costed (in 2010 Australian dollars) to determine the average cost of a generic programme. A multiple cohort Markov model that simulates diseases associated with overweight and obesity was used to estimate the health benefits, measured as health-adjusted life years (HALYs) and healthcare-related cost offsets from diseases averted due to exposure to the intervention. Health and cost outcomes were estimated over the lifetime of the target population. Monte-Carlo simulation was used to assess second-order uncertainty of input parameters to estimate mean incremental cost-effectiveness ratios (ICER) with 95% uncertainty intervals (UIs). Scenario analyses tested variations in programme intensity, target population, and duration of effect. RESULTS The meta-analysis revealed a small but significant difference in BMI z-score (mean difference of - 0.07 (95% UI: - 0.13 to - 0.01)) favouring the CBI community compared with the control. The estimated net cost of implementing CBIs across all local government areas (LGAs) in Australia was AUD426M (95% UI: AUD3M to AUD823M) over 3 years. This resulted in 51,792 HALYs gained (95% UI: 6816 to 96,972) over the lifetime of the cohort. The mean ICER was AUD8155 per HALY gained (95% UI: AUD237 to AUD81,021), with a 95% probability of being cost-effective at a willingness to pay threshold of AUD50,000 per HALY. CONCLUSIONS CBIs are cost-effective obesity prevention initiatives; however, implementation across Australia will be (relatively) expensive when compared with current investments in preventive health.

Abstract
OBJECTIVE To examine the proportion of Native Hawaiian and Pacific Islander (NHPI) meeting recommended physical activity guidelines for Americans (PAG) and determine differences in physical activity (PA) by sex and between NHPI and Asians when data are disaggregated. DESIGN Systematic review and meta-analysis. SETTING Articles identified in CINAHL, The Cochrane Library, Embase, PsychINFO, PubMed, Scopus, SocINDEX, SPORTDiscus, and Web of Science. PARTICIPANTS NHPI children and adults, and Asian adults. INTERVENTIONS Proportion of NHPI meeting PAG and differences in PA involvement by sex and by ethnicity. METHODS Summary reporting for articles, and meta-analysis using random-effects and inverse-various weighted models. CONCLUSIONS AND IMPLICATIONS Just over one-third of NHPI children met the PAG (mean = 38.6%, 95% CI [32.43-45.08]), with more males (42.8%) than females (34.7%) meeting the guidelines (t = 6.74, df = 1, P = .02). Less than half met the PAG for combination (mean = 48.7%, 95% CI [34.69-62.97]), moderate (mean = 47.1%, 95% CI [33.62-61.07]), and about one-third met the PAG for vigorous PA (mean = 33.4%, 95% CI [24.55-43.62]). There were no significant differences between Asians and NHPI in PA. Policy, systems, and environmental changes as well as culturally appropriate interventions are needed to increase physical activity among NHPI.

Abstract
BACKGROUND Multi-setting, multi-component community-based interventions have shown promise in preventing childhood obesity; however, evaluation of these complex interventions remains a challenge. OBJECTIVE The objective of the study is to systematically review published methodological approaches to outcome evaluation for multi-setting community-based childhood obesity prevention interventions and synthesize a set of pragmatic recommendations. METHODS MEDLINE, CINAHL and PsycINFO were searched from inception to 6 July 2017. Papers were included if the intervention targeted children ≤18 years, engaged at least two community sectors and described their outcome evaluation methodology. A single reviewer conducted title and abstract scans, full article review and data abstraction. Directed content analysis was performed by three reviewers to identify prevailing themes. RESULTS Thirty-three studies were included, and of these, 26 employed a quasi-experimental design; the remaining were randomized control trials. Body mass index was the most commonly measured outcome, followed by health behaviour change and psychosocial outcomes. Six themes emerged, highlighting advantages and disadvantages of active vs. passive consent, quasi-experimental vs. randomized control trials, longitudinal vs. repeat cross-sectional designs and the roles of process evaluation and methodological flexibility in evaluating complex interventions. CONCLUSIONS Selection of study designs and outcome measures compatible with community infrastructure, accompanied by process evaluation, may facilitate successful outcome evaluation.

Abstract
Evidence-based obesity reduction programs in the Pacific are scarce to nonexistent. Using a community-based participatory research model (CBPR) we developed a collaboration between our university and a small Pacific Island nation. We established an advisory council of local stakeholders and then conducted an extensive needs assessment with youth, parents, professionals, and lay public. Only 9% of participants had tried a weight loss program. There was a strong tendency to engage in binge-eating cycles; difficulty eating healthy during frequent community celebrations with few healthy food options available in general; and limited traditions that involved physical activity. Participants wanted to learn how to increase their physical activity, make healthier food choices, and learn to reward themselves for healthy behaviors. Diets were most frequently high in energy or protein foods, followed by starch, sugary and fried foods; they ate vegetables and fruits least often. Together, our team then created the culturally relevant Fit Kit Palau©. We highlight lessons learned including how to determine partnerships; manage multiple cultural and geographic barriers; build capacity; and balance program fidelity with responsivity. As the program moves forward, we hope to increase access, engagement, and adherence and provide a model for other PI countries.

Abstract
The Pacific Islands are experiencing an obesity epidemic with a rate of overweight and obesity as high as 80% among adults in some Pacific Island nations. Children and adolescents in the region are also affected by overweight and obesity, which is alarming due to the increased likelihood of remaining overweight as an adult. Research supports an association between poor diet and an increased risk of obesity and development of non-communicable diseases (NCDs). Excess consumption of free sugars is associated with poorer overall diet quality and increased risk of weight gain, chronic inflammation and dental caries. Traditional diets in the Pacific Islands are being supplemented with processed, high-sugar foods and beverages; thus, there is a clear need for effective interventions promoting positive dietary behaviors in the region. School and community based interventions offer an opportunity to promote positive behavior change among children and adolescents. This review aims to evaluate interventions targeting the consumption of high-sugar products in this population in the Pacific Islands.

Abstract
Rigorous estimates of preference-based utilities are important inputs into economic evaluations of childhood obesity interventions, yet no published review currently exists examining utility by weight status in paediatric populations. A comprehensive systematic literature review and meta-analysis was therefore undertaken, pooling data on preference-based health state utilities by weight status in children using a random-effects model. Tests for heterogeneity were performed, and publication bias was assessed. Of 3,434 potentially relevant studies identified, 11 met our eligibility criteria. Estimates of Cohen's d statistic suggested a small effect of weight status on preference-based utilities. Mean utility values were estimated as 0.85 (95% uncertainty interval [UI] 0.84-0.87), 0.83 (95% UI 0.81-0.85), 0.82 (95% UI 0.79-0.84) and 0.83 (95% UI 0.80-0.86) for healthy weight, overweight, obese and overweight/obese states, respectively. Meta-analysis of studies reporting utility values for both healthy weight and overweight/obese participants found a statistically significant weighted mean difference (0.015, 95% UI 0.003-0.026). A small but statistically significant difference was also estimated between healthy weight and overweight participants (0.011, 95% UI 0.004-0.018). Study findings suggest that paediatric-specific benefits of obesity interventions may not be well reflected by available utility measures, potentially underestimating cost-effectiveness if weight loss in childhood/adolescence improves health or well-being.

Abstract
Obesity is a global problem for which sustainable solutions are yet to be realized. Community-based interventions have improved obesity-related behaviours and obesity in the short term. Few papers have explored how to make the interventions and their intended outcomes sustainable. The aim of this paper is to identify factors that contribute to the sustainability of community-based obesity prevention interventions and their intended outcomes. A systematic narrative synthesis review was conducted of published community-based obesity prevention interventions to identify factors contributing to intervention sustainability. Data extracted were included study authors' perspectives of intervention success and sustainability. Eighty-one papers met the inclusion criteria, and from these we identified ten factors that contribute to sustainability: resourcing, leadership, workforce development, community engagement, partnerships, policy, communications, adaptability, evaluation and governance. This review of community-based obesity prevention interventions gives rise to optimism that sustainable change is possible. We propose a framework to help practitioners build sustainability into their interventions and report on them so that others can also benefit.

Abstract
Capacity-oriented approaches to health interventions seek to empower the target population or community to manage the health issue themselves using resources they can control. Positive deviance, resilience and asset-based approaches are three such methods of developing and implementing health interventions. This study aimed to review the efficacy of interventions explicitly applying these methods in addressing childhood obesity using adiposity as the primary outcome, measured by standardized body mass index. The search strategy was developed and implemented across four electronic databases. Of the 181 records identified and screened, 11 studies were identified as using a capacity-oriented approach overall. Asset-based approaches (n = 8 studies) consisted of 47 880 participants, positive deviance (n = 2 studies) consisted of 781 participants, and resilience-based interventions (n = 1 study) consisted of 35 participants. The asset-based approaches were mixed, with three of the eight studies showing a significant reduction in adiposity, while the other five did not find a difference. The positive deviance and resilience-based studies showed signs of efficacy in reducing adiposity. There was significant design heterogeneity across studies, and varied interpretations and definitions of the approaches were used. Further work should attempt to achieve some consensus on the use of these approaches to facilitate comparison and advance the science of capacity-oriented interventions for childhood obesity.

Abstract
OBJECTIVE To examine changes in prevalence of obesity and target health behaviors (fruit, vegetable, and beverage consumption; physical activity; screen time; sleep duration) among students from communities that participated in the Massachusetts Childhood Obesity Research Demonstration (MA-CORD) project compared to controls. METHODS MA-CORD was implemented in two low-income communities. School-level prevalence of obesity among students in first, fourth, and seventh grades was calculated for the intervention communities and nine matched control communities pre and post intervention. Fourth- and seventh-grade students' self-reported health behaviors were measured in intervention communities at baseline and post intervention. RESULTS Among seventh-graders (the student group with greatest intervention exposure), a statistically significant decrease in prevalence of obesity from baseline to post intervention in Community 2 (-2.68%, P = 0.049) and a similar but nonsignificant decrease in Community 1 (-2.24%, P = 0.099) was observed. Fourth- and seventh-grade students in both communities were more likely to meet behavioral targets post intervention for sugar-sweetened beverages (both communities: P < 0.0001) and water (Community 1: P < 0.01; Community 2: P = 0.04) and in Community 2 for screen time (P < 0.01). CONCLUSIONS This multisector intervention was associated with a modest reduction in obesity prevalence among seventh-graders in one community compared to controls, along with improvements in behavioral targets.

Abstract
Background The Pacific TROPIC (Translational Research for Obesity Prevention in Communities) project aimed to design, implement and evaluate a knowledge-broking approach to evidence-informed policy making to address obesity in Fiji. This paper reports on the quantitative evaluation of the knowledge-broking intervention through assessment of participants’ perceptions of evidence use and development of policy/advocacy briefs. Methods Selected staff from six organizations - four government Ministries and two nongovernment organizations (NGOs) - participated in the project. The intervention comprised workshops and supported development of policy/advocacy briefs. Workshops addressed obesity and policy cycles and developing participants’ skills in accessing, assessing, adapting and applying relevant evidence. A knowledge-broking team supported participants individually and/or in small groups to develop evidence-informed policy/advocacy briefs. A questionnaire survey that included workplace and demographic items and the self-assessment tool “Is Research Working for You?” (IRWFY) was administered pre- and post-intervention. Results Forty nine individuals (55% female, 69% 21–40 years, 69% middle-senior managers) participated in the study. The duration and level of participant engagement with the intervention activities varied – just over half participated for 10+ months, just under half attended most workshops and approximately one third produced one or more policy briefs. There were few reliable changes on the IRWFY scales following the intervention; while positive changes were found on several scales, these effects were small (d < .2) and only one individual scale (assess) was statistically significant (p < .05). Follow up (N = 1) analyses of individual-level change indicated that while 63% of participants reported increased research utilization post-intervention, this proportion was not different to chance levels. Similar analysis using scores aggregated by organization also revealed no organizational-level change post-intervention. Conclusions This study empirically evaluated a knowledge-broking program that aimed to extend evidence-informed policy making skills and development of a suite of national policy briefs designed to increase the enactment of obesity-related policies. The findings failed to indicate reliable improvements in research utilization at either the individual or organizational level. Factors associated with fidelity and intervention dose as well as challenges related to organizational support and the measurement of research utilization, are discussed and recommendations for future research presented.

The outcomes of health-promoting communities: being active eating well initiative-a community-based obesity prevention intervention in Victoria, Australia. Int J Obes (Lond) 2017; 41:1080-1090. [PMID: 28321132 DOI: 10.1038/ijo.2017.73] [Citation(s) in RCA: 22] [Impact Index Per Article: 3.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/09/2016] [Revised: 02/13/2017] [Accepted: 03/14/2017] [Indexed: 12/11/2022]
Abstract
OBJECTIVE The aim of this study is to evaluate the impact of the Health-Promoting Communities: Being Active Eating Well (HPC:BAEW, 2007-2010) initiative, which comprised community-based multi-component interventions adapted to community context in five separate communities. The intervention aimed to promote healthy eating, physical activity and stronger, healthier communities. METHODS A mixed method and multilevel quasi-experimental evaluation of the HPC:BAEW initiative captured process, impact and outcome data. The evaluation involved both cross-sectional (children and adolescents) and longitudinal designs (adults) with data collected pre- and post-intervention in intervention (n=2408 children and adolescents from 18 schools, n=501 adults from 22 workplaces) and comparison groups (n=3163 children and adolescents from 33 schools, n=318 adults from seven workplaces). Anthropometry, obesity-related behavioural and environmental data, information regarding community context and implementation factors were collected. The primary outcomes were differences in anthropometry (weight, waist, body mass index (BMI) and standardised BMI (BMI z-score)) over time compared with comparison communities. Baseline data was collected 2008/2009 and post-intervention collected in 2010 with an average intervention time frame of approximately 12 months. RESULTS The strategies most commonly implemented were related to social marketing, stakeholder engagement, network and partnership development, community-directed needs assessment and capacity building. Analysis of post-intervention data showed gains in community capacity, but few impacts on environments, policy or individual knowledge, skills, beliefs and perceptions. Relative to the comparison group, one community achieved a lower prevalence of overweight/obesity, lower weight, waist circumference and BMI (P<0.005). One community achieved a higher level of healthy eating policy implementation in schools; two communities achieved improved healthy eating-related behaviours (P<0.03); one community achieved lower sedentary behaviours; and one community achieved higher levels of physical activity in schools (P<0.05). All effect sizes were in the small-to-moderate range. CONCLUSIONS This was a complex and ambitious initiative, which attempted to expand a previously successful community-based intervention in Victoria into five new contexts and communities. Overall, project success was quite inconsistent, and some significant differences were in the unanticipated direction. However, there are many important learnings that should inform future health-promotion activities. The heterogeneity of outcomes of HPC:BAEW communities reflects the reality of life whereby effectiveness of intervention strategies is dependent on individual and community factors. Future health promotion should consider a systems approach whereby existing systems are modified rather than relying heavily on the addition of new activities, with longer time frames for implementation.

Abstract
Childhood obesity has a complex multi-factorial aetiology grounded in environmental and individual level factors that affect behaviour and outcomes. An ecological, systems-based approach to addressing childhood obesity is increasingly being advocated. The primary aim of this review is to summarize the evidence reported in systematic reviews on the effectiveness of population-level childhood obesity prevention interventions that have an environmental component. We conducted a systematic review of reviews published since 1995, employing a standardized search strategy in nine databases. Inclusion criteria required that reviews be systematic and evaluated at least one population-level, environmental intervention in any setting aimed at preventing or reducing obesity in children (5-18 years). Sixty-three reviews were included, ten of which were of high quality. Results show modest impact of a broad range of environmental strategies on anthropometric outcomes. Systematic reviews vary in methodological quality, and not all relevant primary studies may be included in each review. To ensure relevance of our findings to practice, we also report on relevant underlying primary studies, providing policy-relevant recommendations based on the evidence reviewed. Greater standardization of review methods and reporting structures will benefit policymakers and public health professionals seeking informed decision-making.

Abstract
Objective To examine the relationship between diet quality and depressive symptomology amongst a community-based sample of Fijian adolescents. Methods Participants included 7,237 adolescents (52.6% girls; mean age 15.6 years) at baseline (2005) and 2,948 (56% girls; mean age 17.4 years) at follow-up (2007/2008), from the Pacific Obesity Prevention in Communities Project. Intervention schools (n = 7) were selected from Nasinu, near Suva on the main Fijian island Viti Levu, and comparison schools (n = 11) were chosen from towns on the opposite, west side of the island. A dietary questionnaire was used to measure diet quality. Factor analysis clustered dietary variables into two unique and independent factors, referred to as healthy diet quality and unhealthy diet quality. Depressive symptomology was assessed via the emotional subscale of the Paediatric Quality of Life Inventory. Both measures were self-reported and self-administered. Multiple linear regression was used to test cross-sectional associations (at baseline and follow-up) between diet quality and depressive symptomology. Variables controlled for included gender, age, ethnicity, study condition, BMI-z scores, and physical activity. Findings Strong, positive dose-response associations between healthy diet and high emotional scores (lower depressive symptomology) were found in cross-sectional analyses at baseline and follow-up, among boys and girls. No association was found between emotional health and unhealthy diet. Conclusions This study suggests that cross-sectional relationships exist between a high quality diet during adolescence and less depressive symptoms, however more evidence is required to determine if these two variables are linked causally. Trial population health strategies that use dietary interventions as a mechanism for mental health promotion provide an opportunity to further test these associations. If this is indeed a true relationship, these forms of interventions have the potential to be inexpensive and have substantial reach, especially in Low and Middle Income Countries.

Promoting physical activity for children and adolescents in low- and middle-income countries: An umbrella systematic review: A review on promoting physical activity in LMIC. Prev Med 2016; 88:115-26. [PMID: 27068650 DOI: 10.1016/j.ypmed.2016.03.025] [Citation(s) in RCA: 39] [Impact Index Per Article: 4.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/13/2015] [Revised: 02/01/2016] [Accepted: 03/29/2016] [Indexed: 12/28/2022]
Abstract
OBJECTIVE It is unknown how much previous reviews on promoting physical activity (PA) for children and adolescents (aged 6-18years) take into account studies from low- and middle-income countries (LMIC, based on the World Bank definition) and the level of evidence of the effect of PA interventions in this population. This study aims to answer such questions using an umbrella systematic review approach. METHODS We searched for peer-reviewed systematic reviews and original studies in eight electronic databases, screening of reference lists and expert contacts. Information in systematic reviews on PA interventions for children and adolescents from LMIC was discussed. Original studies on PA interventions (randomized-controlled trials [RCT], cluster-RCT and non-RCT) with children and adolescents from LMIC were eligible. We assessed the methodological quality in all studies, and the evidence level of effect on PA in intervention studies. RESULTS Fifty systematic reviews (nine meta-analyses) and 25 original studies (20 different interventions) met eligibility criteria. Only 3.1% of mentioned studies in previous reviews were from LMIC. Strong and LMIC-specific evidence was found that school-based, multicomponent, and short-term (up to six months) interventions, focused on adolescents primarily (aged 13-18years), can promote PA in children and adolescents from LMIC. Other intervention characteristics had inconclusive evidence due to the low number of studies, low methodological quality, and/or small sample size. CONCLUSION A minimal part of PA interventions mentioned in previous reviews are from LMIC. Our LMIC-specific analyses showed priorities of implementation and practical implication that can be used in public policies for PA promotion in LMIC.

Abstract
BACKGROUND The Massachusetts Childhood Obesity Research Demonstration (MA-CORD) project is a 2-year, multilevel, multisector community intervention to prevent and control obesity among children 2-12 years of age from two predominantly low-income communities in Massachusetts. MA-CORD includes evidence-based interventions in multiple sectors, including community health centers, early care and education centers, schools, afterschool programs, the Special Supplemental Nutrition Program for Women, Infants and Children, and the broader community. Currently, implementation of MA-CORD is complete and the final year of data collection is in progress. Here, the MA-CORD evaluation plan is described and baseline data are presented. METHODS/DESIGN The impact of MA-CORD on children's BMI, lifestyle behaviors, obesity-related care, and quality of life will be assessed using sector-specific, pre/post, time-series, and quasi-experimental designs. Change in the primary outcomes will be compared for intervention and comparison communities. Additionally, change in mean BMI and obesity prevalence in intervention school districts will be compared to similar districts throughout the state. RESULTS At baseline in 2012, approximately 16% of preschool-aged and 25% of school-aged children were obese. Moreover, 15-40% of children consumed no vegetables on the previous day, 25-75% drank a sugar-sweetened beverage on the previous day, up to 87% had insufficient physical activity, 50-75% had a television in the room where they slept, and 50-80% obtained insufficient sleep. CONCLUSIONS There is ample room for improvement in BMI and health behaviors in children in MA-CORD communities. If successful, MA-CORD may serve as a model for multilevel, multisector approaches to childhood obesity prevention and control.

Abstract
PURPOSE The prevalence of overweight/obesity among French Polynesian adolescents is alarming. This study aims to prevent rises in obesity by modifying school food and the physical environment of French Polynesian adolescents. METHODS During the 5-month study, 240 adolescents from a Tubuai island college (in French Polynesia) received a balanced diet based almost exclusively on local agricultural products and fishing by the island community. They were divided into three subgroups according to their college attendance status: external (n = 14), half residents (n = 155), and residents (n = 71). To increase energy expenditure, weekly physical activity was augmented by 2-4 hours of training in Polynesian Va'a canoes. Anthropometric parameters were recorded, and blood samples collected at baseline and after 5 months. Collegians from Rurutu, a neighboring island, were considered as controls (N = 90). RESULTS At baseline, overweight/obesity prevalence was 60% (with 28% obesity) in the intervention group. After 5 months, adjusted weight gain was -.76 kg for residents (95% confidence interval [CI], -1.59 to .08), 1.34 kg for half residents (95% CI, .84-1.83), 1.82 kg for externs (95% CI, .66-2.97), and 4.2 kg (95% CI, 3.4-5.0) in the controls. Our results indicate that the more adolescents were subjected to food and physical activity commitments, the higher was the rate among those who lost weight. We noted that the weight change magnitude predicted insulin, glucose, and visceral obesity modifications. CONCLUSIONS This 5-month school-based intervention slowed weight gain and improved the health of Polynesian collegians. The implementation of longer school-based interventions deserves evaluation.

Abstract
OBJECTIVES This paper aimed to systematically evaluate the mental health and well-being outcomes observed in previous community-based obesity prevention interventions in adolescent populations. SETTING Systematic review of literature from database inception to October 2014. Articles were sourced from CINAHL, Global Health, Health Source: Nursing and Academic Edition, MEDLINE, PsycARTICLES and PsycINFO, all of which were accessed through EBSCOhost. The Cochrane Database was also searched to identify all eligible articles. PRISMA guidelines were followed and search terms and search strategy ensured all possible studies were identified for review. PARTICIPANTS Intervention studies were eligible for inclusion if they were: focused on overweight or obesity prevention, community-based, targeted adolescents (aged 10-19 years), reported a mental health or well-being measure, and included a comparison or control group. Studies that focused on specific adolescent groups or were treatment interventions were excluded from review. Quality of evidence was assessed using the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) guidelines. PRIMARY AND SECONDARY OUTCOME MEASURES Primary outcomes were measures of mental health and well-being, including diagnostic and symptomatic measures. Secondary outcomes included adiposity or weight-related measures. RESULTS Seven studies met the inclusion criteria; one reported anxiety/depressive outcomes, two reported on self-perception well-being measures such as self-esteem and self-efficacy, and four studies reported outcomes of quality of life. Positive mental health outcomes demonstrated that following obesity prevention, interventions included a decrease in anxiety and improved health-related quality of life. Quality of evidence was graded as very low. CONCLUSIONS Although positive outcomes for mental health and well-being do exist, controlled evaluations of community-based obesity prevention interventions have not often included mental health measures (n=7). It is recommended that future interventions incorporate mental health and well-being measures to identify any potential mechanisms influencing adolescent weight-related outcomes, and equally to ensure interventions are not causing harm to adolescent mental health.

Abstract
BACKGROUND Multi-strategic community wide interventions for physical activity are increasingly popular but their ability to achieve population level improvements is unknown. OBJECTIVES To evaluate the effects of community wide, multi-strategic interventions upon population levels of physical activity. SEARCH METHODS We searched the Cochrane Public Health Group Segment of the Cochrane Register of Studies,The Cochrane Library, MEDLINE, MEDLINE in Process, EMBASE, CINAHL, LILACS, PsycINFO, ASSIA, the British Nursing Index, Chinese CNKI databases, EPPI Centre (DoPHER, TRoPHI), ERIC, HMIC, Sociological Abstracts, SPORT Discus, Transport Database and Web of Science (Science Citation Index, Social Sciences Citation Index, Conference Proceedings Citation Index). We also scanned websites of the EU Platform on Diet, Physical Activity and Health; Health-Evidence.org; the International Union for Health Promotion and Education; the NIHR Coordinating Centre for Health Technology (NCCHTA); the US Centre for Disease Control and Prevention (CDC) and NICE and SIGN guidelines. Reference lists of all relevant systematic reviews, guidelines and primary studies were searched and we contacted experts in the field. The searches were updated to 16 January 2014, unrestricted by language or publication status. SELECTION CRITERIA Cluster randomised controlled trials, randomised controlled trials, quasi-experimental designs which used a control population for comparison, interrupted time-series studies, and prospective controlled cohort studies were included. Only studies with a minimum six-month follow up from the start of the intervention to measurement of outcomes were included. Community wide interventions had to comprise at least two broad strategies aimed at physical activity for the whole population. Studies which randomised individuals from the same community were excluded. DATA COLLECTION AND ANALYSIS At least two review authors independently extracted the data and assessed the risk of bias. Each study was assessed for the setting, the number of included components and their intensity. The primary outcome measures were grouped according to whether they were dichotomous (per cent physically active, per cent physically active during leisure time, and per cent physically inactive) or continuous (leisure time physical activity time (time spent)), walking (time spent), energy expenditure (as metabolic equivalents or METS)). For dichotomous measures we calculated the unadjusted and adjusted risk difference, and the unadjusted and adjusted relative risk. For continuous measures we calculated percentage change from baseline, unadjusted and adjusted. MAIN RESULTS After the selection process had been completed, 33 studies were included. A total of 267 communities were included in the review (populations between 500 and 1.9 million). Of the included studies, 25 were set in high income countries and eight were in low income countries. The interventions varied by the number of strategies included and their intensity. Almost all of the interventions included a component of building partnerships with local governments or non-governmental organisations (NGOs) (29 studies). None of the studies provided results by socio-economic disadvantage or other markers of equity. However, of those included studies undertaken in high income countries, 14 studies were described as being provided to deprived, disadvantaged or low socio-economic communities. Nineteen studies were identified as having a high risk of bias, 10 studies were unclear, and four studies had a low risk of bias. Selection bias was a major concern with these studies, with only five studies using randomisation to allocate communities. Four studies were judged as being at low risk of selection bias although 19 studies were considered to have an unclear risk of bias. Twelve studies had a high risk of detection bias, 13 an unclear risk and four a low risk of bias. Generally, the better designed studies showed no improvement in the primary outcome measure of physical activity at a population level.All four of the newly included, and judged to be at low risk of bias, studies (conducted in Japan, United Kingdom and USA) used randomisation to allocate the intervention to the communities. Three studies used a cluster randomised design and one study used a stepped wedge design. The approach to measuring the primary outcome of physical activity was better in these four studies than in many of the earlier studies. One study obtained objective population representative measurements of physical activity by accelerometers, while the remaining three low-risk studies used validated self-reported measures. The study using accelerometry, conducted in low income, high crime communities of USA, emphasised social marketing, partnership with police and environmental improvements. No change in the seven-day average daily minutes of moderate to vigorous physical activity was observed during the two years of operation. Some program level effect was observed with more people walking in the intervention community, however this result was not evident in the whole community. Similarly, the two studies conducted in the United Kingdom (one in rural villages and the other in urban London; both using communication, partnership and environmental strategies) found no improvement in the mean levels of energy expenditure per person per week, measured from one to four years from baseline. None of the three low risk studies reporting a dichotomous outcome of physical activity found improvements associated with the intervention.Overall, there was a noticeable absence of reporting of benefit in physical activity for community wide interventions in the included studies. However, as a group, the interventions undertaken in China appeared to have the greatest possibility of success with high participation rates reported. Reporting bias was evident with two studies failing to report physical activity measured at follow up. No adverse events were reported.The data pertaining to cost and sustainability of the interventions were limited and varied. AUTHORS' CONCLUSIONS Although numerous studies have been undertaken, there is a noticeable inconsistency of the findings in the available studies and this is confounded by serious methodological issues within the included studies. The body of evidence in this review does not support the hypothesis that the multi-component community wide interventions studied effectively increased physical activity for the population, although some studies with environmental components observed more people walking.

Abstract
Nearly one-half of the adult population in Fiji between the ages of 15-64 years is either overweight or obese; and rates amongst school children have, on average, doubled during the last decade. There is an urgent need to scale up the promotion of healthy behaviors and environments using a multi-sectoral approach. The Healthy Youth Healthy Community (HYHC) project in Fiji used a settings approach in secondary schools and faith-based organizations to increase the capacity of the whole community, including churches, mosques and temples, to promote healthy eating and regular physical activity, and to prevent unhealthy weight gain in adolescents aged 13-18 years. The team consisted of a study manager, project coordinator and four research assistants (RAs) committed to planning, designing and facilitating the implementation of intervention programs in collaboration with other stakeholders, such as the wider school communities, government and non-governmental organizations and business partners. Process data were collected on all intervention activities and analyzed by dose, frequency and reach for each specific strategy. The Fiji Action Plan included nine objectives for the school settings; four were based on nutrition and two on physical activity in schools, plus three general objectives, namely capacity building, social marketing and evaluation. Long-term change in nutritional behavior was difficult to achieve; a key contributor to this was the unhealthy food served in the school canteens. Whilst capacity-building proved to be one of the best mechanisms for intervening, it is important to consider the cultural and social factors influencing health behaviors and affecting specific groups.

Abstract
Population-based, 'whole of community' interventions utilise community engagement processes and implement multiple strategies to improve the health of populations defined by geographical boundaries (i.e. cities, villages or regions). The aim of the review was to systematically assess the current state of knowledge about the effectiveness of population-based whole of community interventions in preventing excessive population weight gain. Systematic searches of electronic databases (1990-2011) and reference lists of included trials and previous reviews were conducted to identify interventions to prevent excessive weight gain. Population-based, whole of community interventions were defined as those targeting the weight status of a population characterised along geographical boundaries. The review included eight trials. All of the identified trials targeted children or adolescents. Seven trials reported a significant effect favouring the intervention on at least one measure of adiposity. Meta-analysis of six trials revealed a small reduction in BMI z-score among participants in intervention communities (mean difference (MD) -0.09; 95% confidence interval (CI) -0.16 to -0.02). The review suggests that population-based, whole of community interventions can be effective in achieving modest reductions in population weight gain among children.

Abstract
AIM Our objectives was to identify the characteristics of interventions likely to successfully prevent overweight in youngsters by promoting physical activity (PA), with special focus on dimensions of the socio-ecological model of behaviour and health, and unresolved issues. METHODS This was a systematic review of population-based interventions either promoting PA or limiting sedentary behaviour in children with measure of weight status as an endpoint. The efficacy of studies was evaluated according to the levels of PA determinants in the socio-ecological model (individual, interpersonal, institutional environment, community) targeted by the interventions. RESULTS A total of 54 studies met our inclusion criteria, most of them published within the last 5 years and targeting children aged 6-12 years. Twenty-three interventions targeted individual and/or interpersonal PA determinants only; 26 targeted determinants at three or four levels with at least one environment component at the institutional level; and five were multilevel community-based interventions. Our review indicated that programmes targeting PA determinants at the different levels of the socio-ecological model, including the social and organizational/built environments, had the greatest potential for preventing obesity in youngsters. Targeting various facets of PA, including everyday PA, might represent another key element for program efficacy on weight status. CONCLUSION Data regarding the efficacy of comprehensive PA interventions that simultaneously address individual attitudes and skills, the social context, and the environment, to prevent overweight in children are encouraging. Further studies are needed to evaluate the maintenance of the effects and whether such strategies apply to young children and older adolescents, and to different cultural contexts.

Abstract
Obesity is an emerging problem for African migrants in Australia, but few prevention programs incorporate their cultural beliefs and values. This study reports on the application of community capacity-building and empowerment principles in 4 workshops with Sudanese families in Australia. Workshop participants prioritized health behaviors, skill and knowledge gaps, and environments for change to identify culturally centered approaches to health promotion. The workshops highlighted a need for culturally and age-appropriate interventions that build whole-of-family skills and knowledge around the positive effects of physical activity and nutrition to improve health within communities while reducing intergenerational and gender role family conflicts.

Relationship between overweight and health-related quality of life in secondary school children in Fiji: results from a cross-sectional population-based study. Int J Obes (Lond) 2013; 38:539-46.

Abstract
OBJECTIVE To investigate the relationship between excess weight (overweight and obesity) and health-related quality of life (HRQoL) in a sample of secondary school children in Fiji, by gender, age and ethnicity. METHODS The study comprised 8947 children from forms 3-6 (age 12-18 years) in 18 secondary schools on Viti Levu, the main island of Fiji. Body mass index (BMI) was calculated from measured height and weight, and weight status was classified according to the International Obesity Task Force recommendations. HRQoL was measured by the self-report version of the Pediatric Quality of Life Inventory 4.0. RESULTS HRQoL was similar in children with obesity and normal weight. Generally, this was replicated when analyzed separately by gender and ethnicity, but age stratification revealed disparities. In 12-14-year-old children, obesity was associated with better HRQoL, owing to better social and school functioning and well-being, and in 15-18-year olds with poorer HRQoL, owing to worse physical, emotional and social functioning and well-being (Cohen's d 0.2-0.3). Children with a BMI in the overweight range also reported a slightly lower HRQoL than children with a BMI in the normal weight range, but although statistically significant, the size of this difference was trivial (Cohen's d <0.2). DISCUSSION The results suggest that, overall there is no meaningful negative association between excess weight and HRQoL in secondary school children in Fiji. This is in contradiction to the negative relationship between excess weight and HRQoL shown in studies from other countries and cultures. The assumption that a large body size is associated with a lower quality of life cannot be held universally. Although a generally low HRQoL among children in Fiji may be masking or overriding the potential effect of excess weight on HRQoL, socio-economic and/or socio-cultural factors, may help to explain these relationships.

Abstract
The Pacific Island countries experience some of the highest rates of obesity in the world in part due to substantial dietary changes that mirror changes in the food supply in the region. Economic and political ties, donor aid, and trade links are key drivers of the changing availability and accessibility of processed and imported foods. Pacific Island countries have been innovative in developing trade-related policy approaches to create a less obesogenic food environment. Taxation-based approaches that affect pricing in the region include increased import and excise tariffs on sugared beverages and other high-sugar products, monosodium glutamate, and palm oil and lowered tariffs on fruits and vegetables. Other approaches highlight some higher-fat products through labeling and controlling the supply of high-fat meats. The bans on high-fat turkey tails and mutton flaps highlight the politics, trade agreements and donor influences that can be significant barriers to the pursuit of policy options. Countries that are not signatories to trade agreements may have more policy space for innovative action. However, potential effectiveness and practicality require consideration. The health sector's active engagement in the negotiation of trade agreements is a key way to support healthier trade in the region.

Abstract
Background Evidence-informed policy-making (EIPM) is optimal when evidence-producers (researchers) and policy developers work collaboratively to ensure the production and use of the best available evidence. This paper examined participants’ perceptions of knowledge-brokering strategies used in the TROPIC (Translational Research in Obesity Prevention in Communities) project to facilitate the use of obesity-related evidence in policy development in Fiji. Method Knowledge-brokers delivered a 12-18 month programme comprising workshops targeting EIPM skills and practical support for developing evidence-informed policy briefs to reduce obesity. The programme was tailored to each of the six participating organizations. Knowledge-brokering strategies included negotiating topics that were aligned to the goals of individual organizations, monitoring and evaluating time-management skills, accommodating other organizational and individual priorities, delivering practical sessions on use of appropriate research tools and supporting individual writing of policy briefs. Two qualitative methods were used to examine individuals’ perceptions of skills obtained, opportunities afforded by the TROPIC project, facilitators and inhibiters to planned policy brief development and suggestions for improved programme delivery. Forty-nine participants completed an electronic word table and then participated in a semi-structured interview. An independent interviewer conducted structured interviews with a high-ranking officer in each organization to examine their perceptions of TROPIC engagement strategies. Data were analyzed descriptively and thematically, with the first author and another experienced qualitative researcher analyzing data sets separately, and then combining analyses. Results Many participants believed that they had increased their skills in acquiring, assessing, adapting and applying evidence, writing policy briefs and presenting evidence-based arguments to higher levels. Many participants preferred one-to-one meetings to group activities to ensure early resolution of developing issues and to refine policy briefs. Perceived barriers to EIPM were lack of knowledge about data sources, inadequate time to develop evidence-informed briefs, and insufficient resources for accessing and managing evidence. Conclusion An innovative knowledge-brokering approach utilizing skill development and mentorship facilitated individual EIPM skills and policy brief development. The TROPIC model could stimulate evidence-based policy action relating to obesity prevention and other policy areas in other Pacific countries and elsewhere.

Knowledge brokering between researchers and policymakers in Fiji to develop policies to reduce obesity: a process evaluation. Implement Sci 2013; 8:74. [PMID: 23816188 PMCID: PMC3703278 DOI: 10.1186/1748-5908-8-74] [Citation(s) in RCA: 31] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/24/2012] [Accepted: 06/24/2013] [Indexed: 12/02/2022] Open
Abstract
BACKGROUND The importance of using research evidence in decisionmaking at the policy level has been increasingly recognized. However, knowledge brokering to engage researchers and policymakers in government and non-government organizations is challenging. This paper describes and evaluates the knowledge exchange processes employed by the Translational Research on Obesity Prevention in Communities (TROPIC) project that was conducted from July 2009 to April 2012 in Fiji. TROPIC aimed to enhance: the evidence-informed decisionmaking skills of policy developers; and awareness and utilization of local and other obesity-related evidence to develop policies that could potentially improve the nation's food and physical activity environments. The specific research question was: Can a knowledge brokering approach advance evidence-informed policy development to improve eating and physical activity environments in Fiji. METHODS The intervention comprised: recruiting organizations and individuals; mapping policy environments; analyzing organizational capacity and support for evidence-informed policymaking (EIPM); developing EIPM skills; and facilitating development of evidence-informed policy briefs. Flexible timetabling of activities was essential to accommodate multiple competing priorities at both individual and organizational levels. Process diaries captured the duration, frequency and type of each interaction and/or activity between the knowledge brokering team and participants or their organizations. RESULTS Partnerships were formalized with high-level officers in each of the six participating organization. Participants (n = 49) developed EIPM skills (acquire, assess, adapt and apply evidence) through a series of four workshops and applied this knowledge to formulate briefs with ongoing one-to-one support from TROPIC team members. A total of 55% of participants completed the 12 to18 month intervention, and 63% produced one or more briefs (total = 20) that were presented to higher-level officers within their organizations. The knowledge brokering team spent an average of 30 hours per participant during the entire TROPIC process. CONCLUSIONS Active engagement of participating organizations from the outset resulted in strong individual and organizational commitment to the project. The TROPIC initiative provided a win-win situation, with participants expanding skills in EIPM and policy development, organizations increasing EIPM capacity, and researchers providing data to inform policy.

Abstract
BACKGROUND A 2005 Institute of Medicine report argues that "prevention of obesity in children and youth is, ultimately, about community," yet the literature lacks empirical research on what communities are doing to prevent childhood obesity. This research helps fill this gap and highlights promising practices. CASES This research entailed exploratory analysis of three descriptive case studies of community efforts to prevent childhood obesity in the northeastern United States: Shape Up Somerville in Massachusetts, MA (urban), Whole Community Project in New York, NY (semiurban), and Eat Well Play Hard Chemung in NY (semirural). Data included stakeholder interviews (n=23), participant observation (n ≥ 7 events and meetings/case), and document analysis (n≈100/case) from project inceptions until March, 2010. Meeting participation was tracked. Data were coded for actions and strategies. Actions were mapped to an adapted version of the ANalysis Grid for Environments Linked to Obesity (ANGELO) framework. DISCUSSION These three projects were successful in changing physical environments for food and activity through program and event offerings. The projects were less active in generating policy and economic change. The scale and scope of actions related to project longevity. Demographics of key project stakeholders may have hinged on individual and institutional identities of project facilitators and on intentionality of inclusion strategies. CONCLUSION Such projects could likely generate greater scope and scale of environmental changes to prevent childhood obesity if funding agencies provided long-term financial support and technical assistance, even if at lower levels. Diversity of participation would also benefit from stable support and from dispersal of decision-making powers, including through distributed funding.

Abstract
BACKGROUND Policies targeting obesogenic environments and behaviours are critical to counter rising obesity rates and lifestyle-related non-communicable diseases (NCDs). Policies are likely to be most effective and enduring when they are based on the best available evidence. Evidence-informed policy making is especially challenging in countries with limited resources. The Pacific TROPIC (Translational Research for Obesity Prevention in Communities) project aims to implement and evaluate a tailored knowledge-brokering approach to evidence-informed policy making to address obesity in Fiji, a Pacific nation challenged by increasingly high rates of obesity and concomitant NCDs. METHODS The TROPIC project draws on the concept of 'knowledge exchange' between policy developers (individuals; organisations) and researchers to deliver a knowledge broking programme that maps policy environments, conducts workshops on evidence-informed policy making, supports the development of evidence-informed policy briefs, and embeds evidence-informed policy making into organisational culture. Recruitment of government and nongovernment organisational representatives will be based on potential to: develop policies relevant to obesity, reach broad audiences, and commit to resourcing staff and building a culture that supports evidence-informed policy development. Workshops will increase awareness of both obesity and policy cycles, as well as develop participants' skills in accessing, assessing and applying relevant evidence to policy briefs. The knowledge-broking team will then support participants to: 1) develop evidence-informed policy briefs that are both commensurate with national and organisational plans and also informed by evidence from the Pacific Obesity Prevention in Communities project and elsewhere; and 2) collaborate with participating organisations to embed evidence-informed policy making structures and processes. This knowledge broking initiative will be evaluated via data from semi-structured interviews, a validated self-assessment tool, process diaries and outputs. DISCUSSION Public health interventions have rarely targeted evidence-informed policy making structures and processes to reduce obesity and NCDs. This study will empirically advance understanding of knowledge broking processes to extend evidence-informed policy making skills and develop a suite of national obesity-related policies that can potentially improve population health outcomes.

Abstract
Policy makers throughout the world are struggling to find effective ways to prevent the rising trend of obesity globally, particularly among children. The Pacific Obesity Prevention in Communities project was the first large-scale, intervention research project conducted in the Pacific aiming to prevent obesity in adolescents. The project spanned four countries: Australia, New Zealand, Fiji and Tonga. This paper reports on the strengths and challenges experienced from this complex study implemented from 2004 to 2009 across eight cultural groups in different community settings. The key strengths of the project were its holistic collaborative approach, participatory processes and capacity building. The challenges inherent in such a large complex project were underestimated during the project's development. These related to the scale, complexity, duration, low research capacity in some sites and overall coordination across four different countries. Our experiences included the need for a longer lead-in time prior to intervention for training and up-skilling of staff in Fiji and Tonga, investment in overall coordination, data quality management across all sites and the need for realistic capacity building requirements for research staff. The enhanced research capacity and skills across all sites include the development and strengthening of research centres, knowledge translation and new obesity prevention projects.

Abstract
Obesity is increasing worldwide with the Pacific region having the highest prevalence among adults. The most common precursor of adult obesity is adolescent obesity making this a critical period for prevention. The Pacific Obesity Prevention in Communities project was a four-country project (Fiji, Tonga, New Zealand and Australia) designed to prevent adolescent obesity. This paper overviews the project and the methods common to the four countries. Each country implemented a community-based intervention programme promoting healthy eating, physical activity and healthy weight in adolescents. A community capacity-building approach was used, with common processes employed but with contextualized interventions within each country. Changes in anthropometric, behavioural and perception outcomes were evaluated at the individual level and school environments and community capacity at the settings level. The evaluation tools common to each are described. Additional analytical studies included economic, socio-cultural and policy studies. The project pioneered many areas of obesity prevention research: using multi-country collaboration to build research capacity; testing a capacity-building approach in ethnic groups with very high obesity prevalence; costing complex, long-term community intervention programmes; systematically studying the powerful socio-cultural influences on weight gain; and undertaking a participatory, national, priority-setting process for policy interventions using simulation modelling of cost-effectiveness of interventions.
