Community-Based Participatory Obesity Prevention Interventions in Rural Communities: A Scoping Review.

Child obesity is a worldwide public health concern. In America, children from rural areas have greater odds of obesity in comparison to those from urban areas. Community-engaged research is important for all communities, particularly under-represented communities. This paper reports the results of a scoping review investigating community-engaged research in obesity prevention programs tested with school-aged children in rural America. A literature search of Medline Ovid was conducted to identify interventions reporting the results of obesity prevention interventions that promoted a healthy diet or physical activity (PA) behaviors to school-age children in rural communities of the United States (US). After title and abstract review, potentially relevant citations were further examined by assessing the full text. Each stage of review was conducted by two independent reviewers. Twelve studies met the inclusionary criteria and are included in this review. Most of the studies focused on elementary school participants (n = 7) and improving both diet and PA (n = 9). Out of the twelve studies, only five included the target audience in intervention development or implementation. The most popular type of community engagement was community participation (n = 4). This review revealed that community-engaged research is under-utilized in obesity prevention interventions tested with school-aged children in rural US communities.

Are climate-change actions present in community-based obesity prevention interventions? Development and application of the DoublE-duty actions in CommunIty-baSed obesity InterVEntions (DECISIVE) framework

Abstract Aim Community-based obesity prevention interventions (CBOPIs) target the causes of obesity. Actions implemented in CBOPIs could simultaneously impact both climate change and obesity, making them a potentially important approach. To date, limited work has been undertaken to identify and categorise double-duty actions (those that simultaneously influence obesity and climate change) in CBOPIs. The prevalence of double-duty actions in CBOPIs is currently unknown. This paper outlines the development and application of the DoublE-duty actions in CommunIty-baSed obesity InterVEntions (DECISIVE) framework to address this gap. Subjects and methods A scoping review focusing on obesity and climate change was performed, and the results informed the development of DECISIVE. DECISIVE was applied to studies included in the Cochrane review of obesity prevention interventions in children, and both the published and unpublished data of a completed intervention. Results The scoping review identified one study and one systematic review which contributed to the development of DECISIVE. The framework lists nine double-duty actions, plus an ‘Other’ action. Each action’s potential impact on both obesity and climate change is summarised and example strategies are provided. Reduce the availability and consumption of ultra-processed foods was the most prevalent double-duty action when applying DECISIVE to published studies. Conclusion DECISIVE is the first framework to recognise double-duty actions on obesity and climate change in CBOPIs. The development of DECISIVE holds important implications for community stakeholders who may be able to better identify, incorporate, and promote double-duty actions. This may enhance stakeholder acceptability, feasibility, and value-for-money of interventions.

Using Mixed Methods to Identify Community Needs/Challenges, Assets, and Opportunities for Promoting Healthy Weight in Preschool-Aged Children in Two Rural Communities

ObjectivesChild obesity is a serious public health concern in rural areas. Some multi-level child obesity prevention interventions have been conducted in the U.S., but none have targeted rural areas. This formative study assesses needs/challenges, assets, and opportunities to promote healthy weight in preschool-aged children in two rural communities that will guide the development of a multi-level community-based intervention. MethodsMixed methods were used in two rural communities in Indiana and North Carolina. Parents of children aged 2–5 years participated in focus groups (27 parents) or interviews (14 parents). Childcare providers (n = 13) and stakeholders from 23 community organizations participated in interviews. Observational audits of grocery stores and physical activity resources were conducted using CX3 and the Physical Activity Resource Assessment tools, respectively. ResultsFamily barriers included limited nutrition knowledge, cooking skills, and financial resources. Childcare providers cited a disconnect between childcare and home practices, lack of funding and training in health, and limited childcare options to meet family demands. Community level challenges centered on lack of transportation, limited infrastructure in the built environment to support healthy lifestyles, and limited community activities/opportunities to be physically active. Reported community challenges were supported by audits- 38% of stores carried high-quality fruits/vegetables; 25% met recommended standards for other healthy foods, and the average physical activity environment score was 0.6 (out of 3). Assets included community organizations (food pantries, farmers markets, childcare) that provided access to low-cost healthy meals and avenues for families to connect/learn about healthy lifestyles. Participants recommended that interventions involve community partnerships, target the entire family, improve resource dissemination to the community, leverage existing resources, and explore avenues to improve existing infrastructure. ConclusionsBarriers to healthy weight exist in rural areas, but there are assets that can be leveraged. These findings will guide the development of a rural community-based child obesity prevention intervention. Funding SourcesNIH award (5R03HD097393) and UNC Chapel Hill.

Evaluating the Impact of the Healthy Kids Community Challenge (HKCC) on Physical Activity of Older Youth.

(1) Background: The Healthy Kids Community Challenge (HKCC) was a community-based obesity prevention intervention funded by the Government of Ontario (Canada). (2) Methods: A quasi-experimental design was used to examine the impact of the HKCC on physical activity (PA) outcomes using both repeat cross-sectional (T1 2014–2015, n = 31,548; T2 2015–2016, n = 31,457; and T3 2016–2017, n = 30,454) and longitudinal data (n = 3906) from the COMPASS study. Grade 9–12 students in HKCC communities were placed into one of three intervention groups [T2 data collection post-HKCC finishing (IG1), T2 data collection during HKCC (IG2), and T2 data collection pre-HKCC starting (IG3)], Ontario students in non-HKCC communities were Control Group 1 (CG1) and Alberta students were Control Group 2 (CG2). (3) Results: Repeat cross-sectional results show over time the HKCC had no significant impact on PA outcomes in any of the intervention groups. Longitudinal results show a significant decrease in time spent in moderate-to-vigorous PA (IG2: −3.15 min/day) between T1 and T3 in IG2. (4) Conclusions: These results suggest the HKCC did not have an impact on improving PA outcomes among older youth in HKCC communities. Moving forward, there is a need to provide effective and sustainable interventions to promote PA among older youth.

Three-Year Changes in Low-Income Children's Physical Activity: Prospective Influence of Neighborhood Environment and Parent Supportive Behavior

To prospectively evaluate parent supportive behaviors (PSB) for child physical activity (PA) and neighborhood environment variables on changes in child PA over 3years. Secondary data analysis of the Now Everybody Together for Amazing and Healthful Kids-Worksstudy with 534 parent-child (age 2-4years) dyads randomized to a community-based pediatric obesity prevention intervention for 3years (92% retention). PSB and neighborhood environmental variables were examined in relation to changes in child moderate-to-vigorous PA (MVPA), light and sedentary activity, and screen time. Child and parent accelerometry data were collected at visit 0, 12, 24, and 36months. Mixed multivariate models were used to examine independent and interactive effects of parent-level and neighborhood-level variables on changes in child PA outcomes. PSB significantly interacted with visit on change in child MVPA (β=0.12) and sedentary behaviors (β= -0.18). Over 3years, a 1-unit increase in PSB was associated with an average increase of 4.3minutes/day of MVPA and an average decrease of 6.5minutes/day of sedentary time. Significant main effects were observed for PSB and 3-year change in child screen time (β=-0.05). The children of parents with higher PSB at baseline watched an average of 1.8 fewer minutes/day of screen time compared with parents with lower baseline PSB. Neighborhood-level variables were not significantly associated with changes in child PA outcomes. Parents who increase their supportive behaviors for their child's PA have children who are more physically active and less sedentary over time. Interventions to increase preschool-age children's PA may enhance their effectiveness by targeting parents' supportive behaviors for their child's PA.

The ‘GROW Social Network’ datasets

Abstract The GROW Social Network datasets were compiled as part of a 3-year community-based family-based pediatric obesity prevention intervention (N = 610). The datasets include (i) multiplex edges between adult study participants at four timepoints (baseline, 3, 12, and 36 mon), and (ii) multiplex edges within small intervention-only subgroups (30 groups of approximately 10 adult intervention participants) and a previously validated self-report measure of perceived cohesion at three timepoints (3, 6, and 12 wk). Actor attributes are richly characterized in a linkable dataset.

Changes in weight status, quality of life and behaviours of South Australian primary school children: results from the Obesity Prevention and Lifestyle (OPAL) community intervention program

BackgroundChildhood obesity is a serious public health concern worldwide. Community-based obesity prevention interventions offer promise due to their focus on the broader social, cultural and environmental contexts rather than individual behaviour change and their potential for sustainability and scalability. This paper aims to determine the effectiveness of a South Australian community-based, multi-setting, multi-strategy intervention, OPAL (Obesity Prevention and Lifestyle), in increasing healthy weight prevalence in 9 to 11-year-olds.MethodsA quasi-experimental repeated cross-sectional design was employed. This paper reports on the anthropometric, health-related quality of life (HRQoL) and behaviour outcomes of primary school children (9–11 years) after 2–3 years of intervention delivery. Consenting children from primary schools (20 intervention communities, INT; 20 matched comparison communities, COMP) completed self-report questionnaires on diet, activity and screen time behaviours. HRQoL was measured using the Child Health Utility 9D. Body Mass Index (BMI) z-score and weight status were determined from children’s measured height and weight. A multilevel mixed-effects model, accounting for clustering in schools, was implemented to determine intervention effect. Sequential Bonferroni adjustment was used to allow for multiple comparisons of the secondary outcomes.ResultsAt baseline and final, respectively, 2611 and 1873 children completed questionnaires and 2353 and 1760 had anthropometric measures taken. The prevalence of children with healthy weight did not significantly change over time in INT (OR 1.11, 95%CI 0.92–1.35, p = 0.27) or COMP (OR 0.85, 95%CI 0.68–1.06, p = 0.14). Although changes in the likelihood of obesity, BMI z-score and HRQoL favoured the INT group, the differences were not significant after Bonferroni adjustment. There were also no significant differences between groups at final for behavioural outcomes.ConclusionsOPAL did not have a significant impact on the proportion of 9 to 11-year-olds in the healthy weight range, nor children’s BMI z-score, HRQoL and behaviours. Long-term, flexible community-based program evaluation approaches are required .Trial registrationACTRN12616000477426 (12th April 2016, retrospectively registered).

Collaboration in Complex Systems: Multilevel Network Analysis for Community-Based Obesity Prevention Interventions

Community-based systems interventions represent a promising, but complex approach to the prevention of childhood obesity. Existing studies suggest that the implementation of multiple actions by engaged community leaders (steering committees) is of critical importance to influence a complex system. This study explores two key components of systems interventions: (1) steering committees; and (2) causal loop diagrams (CLDs), used to map the complex community-level drivers of obesity. The interactions between two components create an entangled, complex process difficult to measure, and methods to analyse the dependencies between these two components in community-based systems interventions are limited. This study employs multilevel statistical models from social network analysis to explore the complex interdependencies between steering committee collaboration and their actions in the CLD. Steering committee members from two communities engaged in obesity prevention interventions reported on their collaborative relationships with each other, and where their actions are situated in a locally developed CLD. A multilevel exponential random graph model (MERGM) was developed for each community to explore the structural configurations of the collaboration network, actions in the CLD, and cross-level interactions. The models showed the tendency for reciprocated and transitive collaboration among committee members, as well as some evidence of more complex multilevel configurations that may indicate integrated solutions and collective action. The use of multilevel network analysis represents a step toward unpacking the complexities inherent in community-based systems interventions for obesity prevention.

Cost-effectiveness of community-based obesity prevention interventions in Australia

Cost-effectiveness of community-based obesity prevention interventions in Australia

Cost-effectiveness of community-based childhood obesity prevention interventions in Australia.

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). 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. 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. CBIs are cost-effective obesity prevention initiatives; however, implementation across Australia will be (relatively) expensive when compared with current investments in preventive health.

Comparing complex perspectives on obesity drivers: action-driven communities and evidence-oriented experts.

SummaryIntroductionThe Foresight obesity map represents an expert‐developed systems map describing the complex drivers of obesity. Recently, community‐led causal loop diagrams have been developed to support community‐based obesity prevention interventions. This paper presents a quantitative comparison between the Foresight obesity systems map and a community‐developed map of the drivers of obesity.MethodsVariables from a community‐developed map were coded against the thematic clusters defined in the Foresight map to allow comparison of their sizes and strength of adjoining causal relationships. Central variables were identified using techniques from network analysis. These properties were compared to understand the similarities and differences between the systems as defined by the two groups.ResultsThe community map focused on environmental influences, such as built physical activity environment (18% of variables) and social psychology (38%). The Foresight map's largest cluster was physiology (23%), a minimal focus in the community map (2%). Network analysis highlighted media and available time within both maps, but variables related to school and sporting club environments were unique to the community map.ConclusionCommunity stakeholders focus on modifiable social and environmental drivers of obesity. Capturing local perspectives is critical when using systems maps to guide community‐based obesity prevention.

Engaging Coalitions in Community-Based Childhood Obesity Prevention Interventions: A Mixed Methods Assessment.

Childhood obesity prevention interventions have engaged coalitions in study design, implementation, and/or evaluation to improve research outcomes; yet, no systematic reviews have been conducted on this topic. This mixed methods review aims to characterize the processes and dynamics of coalition engagement in community-based childhood obesity prevention interventions. Data Sources: Studies extracted from Ovid MEDLINE, PubMed, and Web of Science; complementary original survey and interview data among researchers of included studies. Eligible Studies: Multisetting community-based obesity prevention interventions in high-income countries targeting children 0-12 years with anthropometric, behavioral, or environmental/policy outcomes. The Community-Based Participatory Research (CBPR) Conceptual Model was used as an overarching framework. Thirteen studies met inclusion criteria. Elements of CBPR were evident across all studies with community engagement in problem identification (n = 7), design/planning (n = 11), implementation (n = 12), evaluation (n = 4), dissemination (n = 2), and sustainability (n = 10) phases. Five studies reported favorable intervention effects on anthropometric (n = 4), behavioral (n = 1), and/or policy (n = 1) outcomes; descriptive associations suggested that these studies tended to engage community members in a greater number of research phases. Researchers involved in 7 of 13 included studies completed a survey and interview. Respondents recalled the importance of group facilitation, leadership, and shared understanding to multisector coalition work. Perceived coalition impacts included community capacity building and intervention sustainability. This review contributes to a deeper understanding of intervention processes and dynamics within communities engaged in childhood obesity prevention. Future research should more rigorously assess and report on coalition involvement to assess the influence of coalitions on multiple outcomes, including child weight status.

Social network analysis of stakeholder networks from two community-based obesity prevention interventions.

IntroductionStudies of community-based obesity prevention interventions have hypothesized that stakeholder networks are a critical element of effective implementation. This paper presents a quantitative analysis of the interpersonal network structures within a sub-sample of stakeholders from two past successful childhood obesity prevention interventions.MethodsParticipants were recruited from the stakeholder groups (steering committees) of two completed community-based intervention studies, Romp & Chomp (R&C), Australia (2004-2008) and Shape Up Somerville (SUS), USA (2003-2005). Both studies demonstrated significant reductions of overweight and obesity among children. Members of the steering committees were asked to complete a retrospective social network questionnaire using a roster of other committee members and free recall. Each participant was asked to recall the people with whom they discussed issues related to childhood obesity throughout the intervention period, along with providing the closeness and level of influence of each relationship.ResultsNetworks were reported by 13 participants from the SUS steering committee and 8 participants from the R&C steering committee. On average, participants nominated 16 contacts with whom they discussed issues related to childhood obesity through the intervention, with approximately half of the relationships described as ‘close’ and 30% as ‘influential’. The ‘discussion’ and ‘close’ networks had high clustering and reciprocity, with ties directed to other steering committee members, and to individuals external to the committee. In contrast, influential ties were more prominently directed internal to the steering committee, with higher network centralization, lower reciprocity and lower clustering.Discussion and conclusionSocial network analysis provides a method to evaluate the ties within steering committees of community-based obesity prevention interventions. In this study, the network characteristics between a sub-set of stakeholders appeared to be supportive of diffused communication. Future work should prospectively examine stakeholder network structures in a heterogeneous sample of community-based interventions to identify elements most strongly associated with intervention effectiveness.

Sustaining obesity prevention in communities: a systematic narrative synthesis review.

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.

Understanding a successful obesity prevention initiative in children under 5 from a systems perspective.

Introduction/BackgroundSystems thinking represents an innovative and logical approach to understanding complexity in community-based obesity prevention interventions. We report on an approach to apply systems thinking to understand the complexity of a successful obesity prevention intervention in early childhood (children aged up to 5 years) conducted in a regional city in Victoria, Australia.MethodsA causal loop diagram (CLD) was developed to represent system elements related to a successful childhood obesity prevention intervention in early childhood. Key stakeholder interviews (n = 16) were examined retrospectively to generate purposive text data, create microstructures, and form a CLD.ResultsA CLD representing key stakeholder perceptions of a successful intervention comprised six key feedback loops explaining changes in project implementation over time. The loops described the dynamics of collaboration, network formation, community awareness, human resources, project clarity, and innovation.ConclusionThe CLD developed provides a replicable means to capture, evaluate and disseminate a description of the dynamic elements of a successful obesity prevention intervention in early childhood.

Networks for prevention in 19 communities at the start of a large-scale community-based obesity prevention initiative.

Community-based obesity prevention efforts are dependent on the strength and function of collaborative networks across multiple community members and organizations. There is little empirical work on understanding how community network structure influences obesity prevention capacity. We describe network structures within 19 local government communities prior to a large-scale community-based obesity prevention intervention, Healthy Together Victoria, Australia (2012-2015). Participants were from a large, multi-site, cluster randomized trial (cRCT) of a whole-of-systems chronic disease prevention initiative. Community leaders from 12 intervention and seven comparison (non-intervention) regions identified and described their professional networks in relation to dietary, physical activity, and weight status among young children (<5 years of age). Social network measures of density, modularity, clustering, and centrality were calculated for each community. Comparison of means and tests of association were conducted for each network relationship. One-hundred and seven respondents (78 intervention; 29 comparison) reported on 996 professional network relationships (respondent average per region: 10 intervention; 8 comparison). Networks were typically sparse and highly modular. Networks were heterogeneous in size and relationship composition. Frequency of interaction, close and influential relationships were inversely associated with network density. At baseline in this cRCT there were no significant differences between community network structures of key actors with influence over environments affecting children's diet and physical activity. Tracking heterogeneity in both networks and measured outcomes over time may help explain the interaction between professional networks and intervention effectiveness of community-based obesity prevention.

The outcomes of health-promoting communities: being active eating well initiative-a community-based obesity prevention intervention in Victoria, Australia.

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. 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. 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. 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.

Association Between Parent Television-Viewing Practices and Setting Rules to Limit the Television-Viewing Time of Their 8- to 12-Year-Old Children, Minnesota, 2011-2015.

IntroductionTelevision (TV) viewing is popular among adults and children, and child TV-viewing time is positively associated with parent TV-viewing time. Efforts to limit the TV-viewing time of children typically target parent rule-setting. However, little is known about the association between parent TV-viewing practices and rule-setting.MethodsWe used baseline height and weight data and survey data collected from 2011 through 2015 on parents and their 8- to 12-year-old children (N = 212 parent/child dyads) who were participants in 2 community-based obesity prevention intervention trials conducted in metropolitan Minnesota. Multivariable binary logistic regression analysis was used to assess the association between parent TV-viewing time on weekdays or weekend days (dichotomized as ≤2 hrs/d vs ≥2.5 hrs/d) and parent rules limiting child TV-viewing time.ResultsChild mean age was 10 (standard deviation [SD], 1.4) years, mean body mass index (BMI) percentile was 81 (SD, 16.7), approximately half of the sample were boys, and 42% of the sample was nonwhite. Parent mean age was 41 (SD, 7.5) years, and mean BMI was 29 (SD, 7.5); most of the sample was female, and 36% of the sample was nonwhite. Parents who limited their TV-viewing time on weekend days to 2 hours or fewer per day were almost 3 times more likely to report setting rules limiting child TV-viewing time than were parents who watched 2.5 hours or more per day (P = .01). A similar association was not seen for parent weekday TV-viewing time.ConclusionFor most adults and children, a meaningful decrease in sedentariness will require reductions in TV-viewing time. Family-based interventions to reduce TV-viewing time that target the TV-viewing practices of both children and parents are needed.
