RESUMO

BACKGROUND & AIMS: An estimated 38% of adults worldwide have non-alcoholic fatty liver disease (NAFLD). From individual impacts to widespread public health and economic consequences, the implications of this disease are profound. This study aimed to develop an aligned, prioritised fatty liver disease research agenda for the global health community. METHODS: Nine co-chairs drafted initial research priorities, subsequently reviewed by 40 core authors and debated during a three-day in-person meeting. Following a Delphi methodology, over two rounds, a large panel (R1 n = 344, R2 n = 288) reviewed the priorities, via Qualtrics XM, indicating agreement using a four-point Likert-scale and providing written feedback. The core group revised the draft priorities between rounds. In R2, panellists also ranked the priorities within six domains: epidemiology, models of care, treatment and care, education and awareness, patient and community perspectives, and leadership and public health policy. RESULTS: The consensus-built fatty liver disease research agenda encompasses 28 priorities. The mean percentage of 'agree' responses increased from 78.3 in R1 to 81.1 in R2. Five priorities received unanimous combined agreement ('agree' + 'somewhat agree'); the remaining 23 priorities had >90% combined agreement. While all but one of the priorities exhibited at least a super-majority of agreement (>66.7% 'agree'), 13 priorities had <80% 'agree', with greater reliance on 'somewhat agree' to achieve >90% combined agreement. CONCLUSIONS: Adopting this multidisciplinary consensus-built research priorities agenda can deliver a step-change in addressing fatty liver disease, mitigating against its individual and societal harms and proactively altering its natural history through prevention, identification, treatment, and care. This agenda should catalyse the global health community's efforts to advance and accelerate responses to this widespread and fast-growing public health threat. IMPACT AND IMPLICATIONS: An estimated 38% of adults and 13% of children and adolescents worldwide have fatty liver disease, making it the most prevalent liver disease in history. Despite substantial scientific progress in the past three decades, the burden continues to grow, with an urgent need to advance understanding of how to prevent, manage, and treat the disease. Through a global consensus process, a multidisciplinary group agreed on 28 research priorities covering a broad range of themes, from disease burden, treatment, and health system responses to awareness and policy. The findings have relevance for clinical and non-clinical researchers as well as funders working on fatty liver disease and non-communicable diseases more broadly, setting out a prioritised, ranked research agenda for turning the tide on this fast-growing public health threat.

RESUMO

BACKGROUND: Latinos in the United States (U.S.) represent a heterogeneous minority population disproportionally impacted by obesity. Colombians in the U.S. are routinely combined with other South Americans in most obesity studies. Moreover, most studies among Latino immigrants in the U.S. solely focus on factors in the destination context, which largely ignores the prevalence of obesity and contextual factors in their country of origin, and warrant transnational investigations. METHODS: Using 2013-17 data from the New York City Community Health Survey (NYC CHS, U.S.) and the National Survey of the Nutritional Situation (ENSIN, Colombia), Colombians that immigrated to the U.S. and are living in NYC (n = 503) were compared to nonimmigrant Colombians living in their home country (n = 98,829). Prevalence ratios (PR) for obesity (BMI ≥ 30 kg/m2) by place of residence were estimated using multivariable logistic regression adjusting for socio-demographic characteristics and daily consumption of sugar-sweetened beverages. RESULTS: The prevalence of obesity was 49% greater for immigrant Colombians living in NYC when compared to nonimmigrant Colombians living in in their home country (PR = 1.49; 95% CI 1.08, 2.07). Colombian immigrant men in NYC were 72% more likely to have obesity compared to nonimmigrant men living in their home country (PR = 1.72; 95% CI 1.03, 2.87). No significant differences were found in the adjusted models among women. CONCLUSIONS: Colombian immigrants in NYC exhibit a higher prevalence of obesity compared to their nonimmigrant counterparts back home and sex strengthens this relationship. More obesity research is needed to understand the immigration experience of Colombians in the U.S. and the underlying mechanisms for sex difference. Public health action focused on women in Colombia and both Colombian men and women immigrants in the U.S. is warranted to avert the long-term consequences of obesity.

RESUMO

BACKGROUND: Measures of the built environment such as neighborhood walkability have been associated with health behaviors such as physical activity, the lack of which in turn may contribute to the development of diseases such as obesity, diabetes, cardiovascular disease, and cancer. However, limited research has examined these measures in association with health-related quality of life (HR-QoL), particularly in minoritized populations. We examined the relationship between perceived neighborhood environment and HR-QoL in a sample of mostly Black and Latino residents in New York City (NYC). METHODS: This study utilized the baseline survey data from the Physical Activity and Redesigned Community Spaces (PARCS) Study among 1252 residents [34.6% Black, 54.1% Latino, 80.1% female, mean(±SD) age = 38.8 ± 12.5) in 54 park neighborhoods in NYC. Perceived built environment was measured using Neighborhood Environment and Walkability Survey, and mental and physical HR-QoL was estimated using Short Form (SF)-12. Using factor analysis, we identified two subscales of neighborhood walkability: enablers (e.g., trails, sidewalks, esthetics) vs. barriers (e.g., high crime and traffic). In addition, we included a third subscale on neighborhood satisfaction. Generalized Estimating Equation models adjusted for demographics and BMI and accounted for the clustering effect within neighborhood. Multiple imputation was used to account for missing data. RESULTS: Mental HR-QoL was associated with barriers of walkability (ß ± SE = - 1.63 ± 0.55, p < 0.01) and neighborhood satisfaction (ß ± SE = 1.55 ± 0.66, p = 0.02), after adjusting for covariates. Physical HR-QoL was associated with only barriers of walkability (ß ± SE = - 1.13 ± 0.57, p < 0.05). CONCLUSIONS: Among NYC residents living in minoritized neighborhoods, mitigating negative aspects of the neighborhood environment may be more crucial than adding positive features in terms of HR-QoL. Our study points to the need to investigate further the role of the built environment in urban, minoritized communities.

RESUMO

BACKGROUND: Evidence of the effects of the built environment on children has mainly focused on disease outcomes; however, quality of life (QoL) has gained increasing attention as an important health and policy endpoint itself. Research on built environment effects on children's QoL could inform public health programs and urban planning and design. OBJECTIVE: We aimed to review and synthesize the evidence of the relationship between built environment features and children's QoL. METHODS: Five research databases were searched for quantitative peer-reviewed studies on children between 2 and 18 years, published in English or German between January 2010 and August 2023. Only primary research was considered. Included studies (n = 17) were coded and methodologically assessed with the Joanna Briggs Critical Appraisal Checklists, and relevant data were extracted, analyzed, and synthesized, using the following built environment framework: (1) neighborhood green and blue space, (2) neighborhood infrastructure, and (3) neighborhood perception. RESULTS: Green space was positively associated with children's QoL. Infrastructure yielded inconclusive results across all measured aspects. Overall neighborhood satisfaction was positively correlated with higher QoL but results on perceived environmental safety were mixed. CONCLUSIONS: Most studies are correlational, making it difficult to infer causality. While the positive findings of green space on QoL are consistent, specific features of the built environment show inconsistent results. Overall perception of the built environment, such as neighborhood satisfaction, also shows more robust results compared to perceptions of specific features of the built environment. Due to the heterogeneity of both built environment and QoL measures, consistent measures of both concepts will help advance this area of research.

RESUMO

BACKGROUND: Informal food outlets, defined as vendors who rarely have access to water and toilets, much less shelter and electricity, are a common component of the food environment, particularly in many non-Western countries. The purpose of this study was to review available instruments that measure the quality and particularly the healthfulness of food and beverages sold within informal food outlets. METHODS: PubMed, LILACS, Web of Science, and Scopus databases were used. Articles were included if they reported instruments that measured the availability or type of healthy and unhealthy foods and beverages by informal food outlets, were written in English or Spanish, and published between January 1, 2010, and July 31, 2020. Two trained researchers reviewed the title, abstract and full text of selected articles; discrepancies were solved by two independent researchers. In addition, the list of references for selected articles was reviewed for any additional articles of relevance. The quality of published articles and documents was evaluated using JBI Critical appraisal checklist for analytical cross-sectional studies. RESULTS: We identified 1078 articles of which 14 were included after applying the selection criteria. Three additional articles were considered after reviewing the references from the selected articles. From the final 17 articles, 13 measurement tools were identified. Most of the instruments were used in low- and middle-income countries (LMIC). Products were classified as healthy/unhealthy or produce/non-produce or processed/unprocessed based on availability and type. Six studies reported psychometric tests, whereas one was tested within the informal food sector. CONCLUSIONS: Few instruments can measure the healthfulness of food and beverages sold in informal food outlets, of which the most valid and reliable have been used to measure formal food outlets as well. Therefore, it is necessary to develop an instrument that manages to measure, specifically, the elements available within an informal one. These actions are extremely important to better understand the food environment that is a central contributor to poor diets that are increasingly associated with the obesity and Non-communicable disease (NCD) pandemic.

RESUMO

BACKGROUND: Immigrants are disproportionally impacted by HIV infection in Europe and in Spain. Immigrants are also identified as a vulnerable population during economic crises. Various socioeconomic barriers hinder HIV-positive immigrants from accessing healthcare services in the host country. As a result of the 2008 financial crisis, Spain has implemented multiple austerity measures, one of which was the enactments of Royal Decree Law (RDL) 16/2012 and Royal Decree (RD) 1192/2012 which abolished universal healthcare coverage. In this context, this study examined: 1) Participants' mixed experiences in accessing health care after the enactment of 2012 RDL and RD, and 2) Distress felt by the participants and their experiences as HIV-positive immigrants living in Spain. METHODS: Participants were recruited through a nongovernmental organization (NGO) during routine visits at the center. A total of 12 participants were interviewed to reach data saturation. Participants were HIV-positive immigrants living in Spain for 1 or more years, allowing for substantial experience with navigating the healthcare system. Thematic analysis was performed to identify common themes in participants' experiences living as HIV-positive individuals in Spain and in accessing healthcare. RESULTS: Four primary themes were identified. The primary systemic barrier to accessing health care encountered by participants was the inability to fulfill the requirement of having proof of registration in an Autonomous Community for the required time period, thus not being able to apply for a public health insurance card and utilize free care services. Participants identified a positive impact of third party (NGO, social worker, friend/family member) guidance on their experience of applying for a public health insurance card. Participants expressed experiencing emotional or physical (eg, side effects of medication) distress in adapting to life as HIV-positive individuals. Participants also identified experiencing discrimination while living as HIV-positive immigrants in Spain. CONCLUSIONS: HIV-positive immigrants are underserved in Spain. They encounter systemic barriers while accessing healthcare services, and experience fear and/or discrimination. The study underscores the role of NGOs in helping HIV-positive immigrants navigate the healthcare system. More research is needed on comprehensive approaches to address healthcare needs of HIV-positive immigrants in Spain.

RESUMO

BACKGROUND: In 2012, the central government of Spain enacted Royal Decree-Law (RDL) 16/2012 and Royal Decree (RD) 1192/2012, which abolished universal healthcare coverage, thus limiting access to care for undocumented immigrants. Free health care was also no longer granted to anyone who has never been employed. In this context, this study investigated the prevalence of late HIV diagnoses (LHDs) among immigrants living in Spain vs. native-born Spaniards. METHODS: Data (n = 5943) from the 2010 to 2015 Cohort of the Spanish AIDs Research Network were used, including HIV-positive and antiretroviral therapy (ART)-naïve patients throughout Spain. Multivariate logistic models were fitted to compare the prevalence of LHD among the groups, adjusting for covariates. RESULTS: The prevalence of LHD in the total sample was 39.5%. Compared with native-born Spaniards (n = 4445), immigrants (n = 1488) were more likely to have LHD (37.4% vs. 45.7%, respectively; P < 0.001). Multivariate analysis showed that the prevalence ratio of LHD among immigrants vs. native-born Spaniards was 1.15 [95% confidence interval (CI), 1.02-1.28], after adjusting for covariates. This disparity widened from 2010 to 2011 (APR = 1.14, 95% CI, 1.02-1.29) to 2012-15 (APR = 1.28, 95% CI, 1.17-1.39), although the change was not statistically significant. CONCLUSIONS: Immigrants in Spain had a higher risk of LHD compared with native-born counterparts. LHD is an important healthcare marker due to the positive benefits of early HIV diagnosis, including prevention, improvements in health outcomes and decreases in overall cost of treatment. More research is needed on the causes of the disparity and potential social and policy interventions to reduce the prevalence of LHD among immigrants.

RESUMO

Importance: Rural populations have a higher prevalence of obesity and poor access to weight loss programs. Effective models for treating obesity in rural clinical practice are needed. Objective: To compare the Medicare Intensive Behavioral Therapy for Obesity fee-for-service model with 2 alternatives: in-clinic group visits based on a patient-centered medical home model and telephone-based group visits based on a disease management model. Design, Setting, and Participants: Cluster randomized trial conducted in 36 primary care practices in the rural Midwestern US. Inclusion criteria included age 20 to 75 years and body mass index of 30 to 45. Participants were enrolled from February 2016 to October 2017. Final follow-up occurred in December 2019. Interventions: All participants received a lifestyle intervention focused on diet, physical activity, and behavior change strategies. In the fee-for-service intervention (n = 473), practice-employed clinicians provided 15-minute in-clinic individual visits at a frequency similar to that reimbursed by Medicare (weekly for 1 month, biweekly for 5 months, and monthly thereafter). In the in-clinic group intervention (n = 468), practice-employed clinicians delivered group visits that were weekly for 3 months, biweekly for 3 months, and monthly thereafter. In the telephone group intervention (n = 466), patients received the same intervention as the in-clinic group intervention, but sessions were delivered remotely via conference calls by centralized staff. Main Outcomes and Measures: The primary outcome was weight change at 24 months. A minimum clinically important difference was defined as 2.75 kg. Results: Among 1407 participants (mean age, 54.7 [SD, 11.8] years; baseline body mass index, 36.7 [SD, 4.0]; 1081 [77%] women), 1220 (87%) completed the trial. Mean weight loss at 24 months was -4.4 kg (95% CI, -5.5 to -3.4 kg) in the in-clinic group intervention, -3.9 kg (95% CI, -5.0 to -2.9 kg) in the telephone group intervention, and -2.6 kg (95% CI, -3.6 to -1.5 kg) in the in-clinic individual intervention. Compared with the in-clinic individual intervention, the mean difference in weight change was -1.9 kg (97.5% CI, -3.5 to -0.2 kg; P = .01) for the in-clinic group intervention and -1.4 kg (97.5% CI, -3.0 to 0.3 kg; P = .06) for the telephone group intervention. Conclusions and Relevance: Among patients with obesity in rural primary care clinics, in-clinic group visits but not telephone-based group visits, compared with in-clinic individual visits, resulted in statistically significantly greater weight loss at 24 months. However, the differences were small in magnitude and of uncertain clinical importance. Trial Registration: ClinicalTrials.gov Identifier: NCT02456636.

RESUMO

This study used interviews with New York City Hispanic Caribbean (HC) restaurant owners, managers, and cooks/chefs (n=19) to examine perceptions concerning the healthfulness of the HC diet and diet-related disparities in the HC community, and document factors potentially influencing their engagement in community nutrition interventions. The interviews revealed high awareness of diet-related issues. Respondents had mixed notions concerning their role in improving community food environments, noting important barriers for collaboration to consider in future interventions. The study underscores the important role of ethnic restaurants, providing information to facilitate engagement with this largely untapped sector in immigrant/ethnic communities in the US.

RESUMO

Background/aim: Body esteem (BE) is defined as the self-evaluation of one's own body or appearance. The Body Esteem Scale for Adolescents and Adults (BESAA)consists of three subscales: BE-appearance, BE-weight, and BE-attribution. Though initially developed for adolescents and adults, the use of the scale has recently increased in health-related research on children. This study aimed to assess the validity and reliability of the Turkish version of the BESAA for children. Materials and methods: The participants in the study were 4th grade children (aged 9­10 years) in Ankara, Turkey. The validity of the scale was evaluated through exploratory and confirmatory factor analyses. Internal consistency and test-retest reliability were assessed using Cronbach's alpha and Spearman's rho correlation coefficient, respectively. Results: The Turkish version of the BESAA for children includes BE-weight, BE-appearance, and BE-attribution subscales. The scale demonstrated good model fit statistics (chi-square/df = 3.41, P < 0.001) and good internal consistency for BE-weight (α = 0.85), BE-appearance (α = 0.76), and BE-attribution (α = 0.69). According to our findings, test-retest reliability of the three subscales was in the moderate/acceptable range for children (r = 0.57­0.68, P < 0.01). Conclusion: The Turkish version of the BESAA can be used to measure BE in terms of appearance, weight, and attribution in children.

RESUMO

PURPOSE: The purpose of this study was to inform public policy opportunities to reduce childhood obesity by identifying parents' perceptions of factors contributing to childhood obesity, attribution of responsibility, and the extent of their support for public prevention policies with attention to socio-economic status. DESIGN AND METHODS: In 2015, 2066 parent-child dyads across socio-economic strata from 43 randomly selected schools in Ankara completed surveys and measurements to examine perceptions, attribution, and prevention policies related to childhood obesity. RESULTS: Parents across the socio-demographic spectrum recognized obesity as a serious problem. Unhealthy food availability was identified as the leading cause of while industry and media were credited with having the greatest responsibility for childhood obesity. There was strong public support for policy strategies targeting schools, marketing, and the built environment, though support tempered as socio-economic status and parental education decreased. CONCLUSIONS: This survey provided insight into parents' knowledge and beliefs surrounding childhood obesity as well as their endorsement of related prevention strategies. Educational messages that address variations in SES to describe the causes of childhood obesity and connect those causes to actionable community prevention strategies may improve community support for enhanced policy actions within and beyond school settings.

RESUMO

Despite isolated areas of improvement, no country to date has reversed its obesity epidemic. Governments, together with a broad range of stakeholders, need to act urgently to decrease the prevalence of obesity. In this Series paper, we review several regulatory and non-regulatory actions taken around the world to address obesity and discuss some of the reasons for the scarce and fitful progress. Additionally, we preview the papers in this Lancet Series, which each identify high-priority actions on key obesity issues and challenge some of the entrenched dichotomies that dominate the thinking about obesity and its solutions. Although obesity is acknowledged as a complex issue, many debates about its causes and solutions are centred around overly simple dichotomies that present seemingly competing perspectives. Examples of such dichotomies explored in this Series include personal versus collective responsibilities for actions, supply versus demand-type explanations for consumption of unhealthy food, government regulation versus industry self-regulation, top-down versus bottom-up drivers for change, treatment versus prevention priorities, and a focus on undernutrition versus overnutrition. We also explore the dichotomy of individual versus environmental drivers of obesity and conclude that people bear some personal responsibility for their health, but environmental factors can readily support or undermine the ability of people to act in their own self-interest. We propose a reframing of obesity that emphasises the reciprocal nature of the interaction between the environment and the individual. Today's food environments exploit people's biological, psychological, social, and economic vulnerabilities, making it easier for them to eat unhealthy foods. This reinforces preferences and demands for foods of poor nutritional quality, furthering the unhealthy food environments. Regulatory actions from governments and increased efforts from industry and civil society will be necessary to break these vicious cycles.

RESUMO

Public mobilisation is needed to enact obesity-prevention policies and to mitigate reaction against their implementation. However, approaches in public health focus mainly on dialogue between public health professionals and political leaders. Strategies to increase popular demand for obesity-prevention policies include refinement and streamlining of public information, identification of effective obesity frames for each population, strengthening of media advocacy, building of citizen protest and engagement, and development of a receptive political environment with change agents embedded across organisations and sectors. Long-term support and investment in collaboration between diverse stakeholders to create shared value is also important. Each actor in an expanded coalition for obesity prevention can make specific contributions to engaging, mobilising, and coalescing the public. The shift from a top-down to a combined and integrated bottom-up and top-down approach would need an overhaul of current strategies and reprioritisation of resources.

RESUMO

Preventing and managing youth-onset type 2 diabetes are a major challenge. This paper reviews the evidence of lifestyle and drug therapies in improving glucose, insulin, and insulin sensitivity. Forty-four interventions were analyzed, of which 11 were drug (mainly metformin) interventions combined with lifestyle while the remainder used lifestyle strategies only. Fewer than a dozen out of 44 interventions reported significant improvements in glucose-related outcomes. Metformin in addition to lifestyle therapy did not necessarily enhance intervention effects. The overall lack of findings can be partially attributed to the heterogeneity of study populations, the lack of intervention intensity, under-powered study design, and the challenging lives of at-risk populations. New treatment options in both drugs and lifestyle strategies are direly needed.

RESUMO

We examined evidence regarding the influence of school physical environment on healthy-eating outcomes. We applied a systems perspective to examine multiple disciplines' theoretical frameworks and used a mixed-methods systematic narrative review method, considering both qualitative and quantitative sources (published through March 2014) for inclusion. We developed a causal loop diagram from 102 sources identified. We found evidence of the influence of many aspects of a school's physical environment on healthy-eating outcomes. The causal loop diagram highlights multilevel and interrelated factors and elucidates the specific roles of design and architecture in encouraging healthy eating within schools. Our review highlighted the gaps in current evidence and identified areas of research needed to refine and expand school architecture and design strategies for addressing healthy eating.

RESUMO

BACKGROUND: Diet is a major determinant of obesity; however, findings from the studies examining how dieting to lose weight affects weight gain have been inconclusive. PURPOSE: Our aim was to examine the longitudinal association of frequency of dieting for weight loss with (a) obesity status and (b) body mass index (BMI) change. METHODS: We used data from Waves 9 (2009) and 10 (2010) of the Household Income and Labour Dynamics in Australia (HILDA) survey. Binominal logistic regression estimated the association of frequency of dieting in 2009 on probability of obesity in 2010. Multinomial logistic regression estimated the association of frequency of dieting in 2009 on the probability of BMI gain versus BMI maintenance and BMI loss between 2009 and 2010. The analysis sample size was 8824. RESULTS: Compared to those who were never on a diet in the previous year, the odds of obesity were 1.9, 2.9, and 3.2 times higher among those who were on a diet once, more than once, and always, respectively. Similarly, the odds of BMI gain versus BMI maintenance and also versus BMI loss were higher among those who dieted than those who did not. CONCLUSIONS: Dieting to lose weight can contribute to the risk of future obesity and weight gain.

RESUMO

INTRODUCTION: In 2014 the US Food and Drug Administration proposed a series of changes to its 1992 guidelines on nutrition facts labeling to help consumers make informed food choices. To date, few studies have examined the association between consumers' use of the nutrition label and health. The objective of this study was to assess the association between nutrition label use and health and to determine whether the association differs by sex. METHODS: Using data from a population-based, random sample survey of 1,503 participants conducted in Nebraska in 2013, we performed χ(2) tests to examine bivariate associations between selected health variables and nutrition label use, followed by logistic regression analysis to estimate these associations in a multivariate framework. RESULTS: A U-shaped relationship between self-rated health (SRH) and nutrition label use was observed. Both excellent and poor SRH were associated with a higher likelihood of nutrition label use than the 3 SRH categories in between. Being obese or having 1 of 4 chronic conditions (hypertension, diabetes, heart disease, high cholesterol) were both associated with higher odds of nutrition label use (odds ratio [OR] = 2.63, P < .001; OR = 1.71, P < .05, respectively) among men. These associations, however, were not significant among women. CONCLUSION: A close association existed between health and nutritional label use. This association was more pronounced among men than among women. Nutrition education may benefit from factoring in the association between health and use of nutrition labels and the differences in these associations by sex.

RESUMO

BACKGROUND: A community's readiness for change is a precursor to the effective application of evidence-based practices for health promotion. Research is lacking regarding potential strategies to improve readiness to address obesity-related health issues in underserved communities. COMMUNITY CONTEXT: This case study describes SaludABLEOmaha, an initiative to increase readiness of residents in a Midwestern Latino community to address obesity and adopt healthy lifestyles. METHODS: SaludABLEOmaha emphasized 2 core approaches, youth activism and collaboration among public and private institutions, which we applied to planning and implementing tactics in support of 3 interconnected strategies: 1) social marketing and social media, 2) service learning in schools (ie, curricula that integrate hands-on community service with instruction and reflection), and 3) community and business engagement. Following the Community Readiness Model protocol (http://triethniccenter.colostate.edu/communityReadiness.htm), structured interviews were conducted with community leaders and analyzed before and 2.5 years after launch of the program. OUTCOME: The community increased in readiness from stage 3 of the Community Readiness Model, "vague awareness," at baseline to stage 5, "preparation," at follow-up. INTERPRETATION: SaludABLEOmaha improved community readiness (eg, community knowledge, community climate), which probably contributed to the observed increase in readiness to address obesity through healthy lifestyle. Community mobilization approaches such as youth activism integrated with social marketing and social media tactics can improve community responsiveness to obesity prevention and diminish health disparities.

RESUMO

This article describes a pilot youth advocacy initiative for obesity prevention informed by social cognitive theory, social network theory, and theories of community mobilization. With assistance from school and health leaders, adolescent-aged youth led a cafeteria food labeling and social marketing campaign. We implemented an anonymous survey 2 weeks prior to and again at the conclusion of the campaign, and used cafeteria records to track servings of fruits and vegetables. The campaign resulted in a significant increase in youths' confidence to identify healthy foods (OR 1.97, 95 % CI 1.01, 3.84, p = .048), and a significant increase in per person per day servings of fruits (0.02, p = .03) and vegetables (0.01, p = .02). The results of our pilot were promising, and the integration of concepts from multiple theories benefited the implementation process. Obesity prevention initiatives should include strategies that encourage youth to create health promotion community networks and lead changes to their social and physical environments.
