[PMID: 34519632 DOI: 10.1080/07448481.2021.1970563] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/01/2020] [Revised: 07/28/2021] [Accepted: 08/16/2021] [Indexed: 06/13/2023]
Abstract
Objective: To evaluate the process of implementation and impact of a front-of-pack labeling intervention on purchases of labeled food products. Participants: A convenience sample of 111 college students were recruited to complete a survey as they exited markets where the intervention was being implemented. Participants had to have purchased at least one consumable item. Methods: Intercept surveys and audits were conducted at three markets, two times each over a period of three weeks. Results: The audits indicated high implementation fidelity (82% overall). However, customer surveys revealed that only 42% noticed the front-of-pack sticker, and the majority (89%) did not purchase an item with the sticker. However, customers who noticed the sticker were significantly more likely to purchase an item with the sticker (p = .002). Conclusions: These findings provide preliminary evidence for the feasibility and effectiveness of a front-of-pack labeling intervention in a university market setting.

Evaluation of community-based health promotion interventions in children and adolescents in high-income countries: a scoping review on strategies and methods used. BMC Public Health 2023; 23:845. [PMID: 37165313 PMCID: PMC10170055 DOI: 10.1186/s12889-023-15691-y] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/15/2022] [Accepted: 04/16/2023] [Indexed: 05/12/2023] Open
Abstract
BACKGROUND In recent decades, community-based interventions have been increasingly adopted in the field of health promotion and prevention. While their evaluation is relevant for health researchers, stakeholders and practitioners, conducting these evaluations is also challenging and there are no existing standards yet. The objective of this review is to scope peer-reviewed scientific publications on evaluation approaches used for community-based health promotion interventions. A special focus lies on children and adolescents' prevention. METHODS A scoping review of the scientific literature was conducted by searching three bibliographic databases (Medline, EMBASE, PsycINFO). The search strategy encompassed search terms based on the PCC (Population, Concept, Context) scheme. Out of 6,402 identified hits, 44 articles were included in this review. RESULTS Out of the 44 articles eligible for this scoping review, the majority reported on studies conducted in the USA (n = 28), the UK (n = 6), Canada (n = 4) and Australia (n = 2). One study each was reported from Belgium, Denmark, Germany and Scotland, respectively. The included studies described interventions that mostly focused on obesity prevention, healthy nutrition promotion or well-being of children and adolescents. Nineteen articles included more than one evaluation design (e.g., process or outcome evaluation). Therefore, in total we identified 65 study designs within the scope of this review. Outcome evaluations often included randomized controlled trials (RCTs; 34.2%) or specific forms of RCTs (cluster RCTs; 9.8%) or quasi-experimental designs (26.8%). Process evaluation was mainly used in cohort (54.2%) and cross-sectional studies (33.3%). Only few articles used established evaluation frameworks or research concepts as a basis for the evaluation. CONCLUSION Few studies presented comprehensive evaluation study protocols or approaches with different study designs in one paper. Therefore, holistic evaluation approaches were difficult to retrieve from the classical publication formats. However, these publications would be helpful to further guide public health evaluators, contribute to methodological discussions and to inform stakeholders in research and practice to make decisions based on evaluation results.

Front Public Health 2022; 9:789535. [PMID: 35004591 PMCID: PMC8734426 DOI: 10.3389/fpubh.2021.789535] [Citation(s) in RCA: 9] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/05/2021] [Accepted: 11/30/2021] [Indexed: 12/21/2022] Open
Abstract
Background: Traditionally, adolescent participation in research has been tokenistic. Adolescents are rarely afforded the opportunity to influence decision-making in research designed to prevent obesity. Engaging adolescents in meaningful decision-making may enhance research translation. This review aimed to analyze the current modes and nature of adolescent participation in obesity prevention research decision-making. Methods: A systematic scoping review was conducted using Arksey and O'Malley's six-stage framework. Six major databases were searched for peer-reviewed primary research studies with adolescent participation related to obesity, physical activity, and diet. Modes of adolescent participation were categorized based on the Lansdown-UNICEF conceptual framework for measuring outcomes of adolescent participation. The framework outlines three modes of meaningful participation: (i) consultative, which involves taking opinions and needs into consideration; (ii) collaborative, where adolescents are partners in the decision-making process; and (iii) adolescent-led participation where adolescents have the capacity to influence the process and outcomes. The degree of involvement in research cycles was classified based on the National Health and Medical Research Council consumer engagement framework. Five stages of the research cycle were determined: identify, design and develop, conduct, analyze and disseminate. Results: In total, 126 papers describing 71 unique studies were identified. Of these, 69% (49/71) took place in the USA, and 85% (52/61) were conducted in minority or underserved communities, while males were more likely to be under-represented. In 49% (35/71) of studies, participation was consultative and 9% (6/71) of studies involved an adolescent-led approach. Furthermore, 87% (62/71) of studies incorporated adolescent participation in one or more of the research cycle's formative phases, which involve eliciting views, opinions and idea generation. Only 11% of studies engaged adolescents in all five stages of the research cycle where adolescents could have more influence over the research process. Conclusion: Meaningful adolescent participation in the obesity prevention research cycle is limited. Empowering and mobilizing equal partnership with adolescents should be at the forefront of all adolescent-related obesity prevention research.

Abstract
BACKGROUND Culinary medicine (CM) or culinary nutrition (CN) education provided to professionals with the capacity to influence behaviour change is an emerging strategy to promote diet quality and reduce the burden of diet related chronic disease in adults. The purpose of this scoping review was to synthesise current research describing CM/CN education provided to or by health, education and culinary professionals, or students of these disciplines. METHODS Preferred Reporting Items for Systematic reviews and Meta-Analysis extension for Scoping Reviews (PRISMA-ScR) was used. Eleven electronic databases were searched in March 2019. Included studies were: (i) nutrition, health or lifestyle programs with a CM/CN component; (ii) study participants or programs facilitated by people working or training in health, community and/or adult education, or culinary roles where facilitator training was described; (iii) reported in the English language; and (iv) published from 2003. RESULTS In total, 33 studies were included. Nineteen studies delivered programs to general population groups and were facilitated by health professionals and/or health university students. Fourteen studies delivered CM/CN training to health professionals or students. Studies reported changes in participants' culinary skill and nutrition knowledge (n = 18), changes in dietary intake (n = 13), attitudes and behaviour change in healthy eating and cooking (n = 4), and competency in nutrition counselling and knowledge (n = 7). CONCLUSIONS Further research examining the effectiveness of CM/CN programs, and that describes optimal content, format and timing of the programs, is needed. Research evaluating the impact of training in CM/CN to education and culinary professionals on healthy cooking behaviours of their patients/clients is warranted.

Themes in Train-the-Trainer Nutrition Education Interventions Targeting Middle School Students: A Systematic Review. Nutrients 2021; 13:2749.

Abstract
Context-appropriate nutrition education interventions targeting middle school students have the potential to promote healthy dietary patters that may help prevent unnecessary weight gain at a point in childhood development when youth experience increasing agency over their food choices. The aim of this review was to identify and synthesize themes in train-the-trainer approaches, intervention content and delivery, and youth receptivity across teacher, mentor, and peer-led nutrition education interventions that targeted middle school-age youth in urban, primarily low-income settings. A systematic, electronic literature search was conducted in seven electronic databases, PubMed/Medline, CINAHL, ERIC, PsycINFO, Scopus, SPORTDiscus, and Cochrane CENTRAL, using fixed inclusion and exclusion criteria. A total of 53 papers representing 39 unique interventions were selected for data extraction and quality assessment. A framework synthesis approach was used to organize the interventions into six categories and identify themes according to whether the intervention was classroom-based or out-of-school-based and whether adults, cross-age peers or same-age peers delivered the intervention. Ten of the interventions contained multiple components such that they were included in two of the categories. The review findings indicated that trainings should be interactive, include opportunities to role-play intervention scenarios and provide follow-up support throughout intervention delivery. Interventions targeting middle school youth should include positive messaging and empower youth to make healthy choices within their specific food environment context.

Abstract
The prevalence of obesity remains high among school age children and continues to rise among adolescents in the United States. One strategy to address this challenge is to use peer rather than professional leaders to run weight management programs. Youth peer-led lifestyle interventions have become increasingly common over the last few decades, but there is a lack of review and synthesis of these programs. The purpose of this manuscript was to critically review and synthesize results and lessons learned from evaluated youth peer-led lifestyle modification and weight management programs. We searched the PubMed/MEDLINE database to identify articles published between March 2002 and December 2015. We identified 29 interventions including children from kindergarten to 12th grade from different settings and racial/ethnic and economic backgrounds. We first summarized descriptive information about the interventions and then compared outcomes based on intervention type, peer leader characteristics and training, and other related factors. Our review indicated that youth peer-led interventions of varying structure and content can result in positive changes in behavioral influences, diet, physical activity, body measures and other clinical outcomes. We used information from our analysis to formulate recommendations for design of future youth peer-led lifestyle interventions.

Abstract
Food access literature links disinvested communities with poor food access. Similarly, links are made between discriminatory housing practices and contemporary investment. Less work has examined the relationship between housing practices and food environment disparities. Our central premise is that these practices create distinctions in food environment quality, and that these disparities may have implications for food system advocacy and policymaking. In this paper, we link an objective food environment assessment with a spatial database highlighting redlining, blockbusting, and gentrification in Baltimore, Maryland, USA. Standard socioeconomic and housing characteristics are used to control for race, income, and housing composition in a multivariate regression analysis. Our findings highlight that blockbusting-rather than redlining-most strongly shapes poor food access. Redlining and gentrification, meanwhile, are associated with better food access. These findings raise important points about future policy discussions, which should instead be focused on ameliorating more contemporary patterns of housing inequality.

Abstract
OPREVENT2 was a multilevel, multicomponent (MLMC) adult obesity prevention that sought to improve access and demand for healthier food and physical activity opportunities in six Native American communities in the Southwest and Midwest. OPREVENT2 worked with worksites, food stores, schools (grades 2-6), through social media and mailings, and with a local community action committee (CAC), in each of the three intervention communities, and was implemented in six phases. We conducted a process evaluation to assess implementation of each intervention component in terms of reach, dose delivered and fidelity. Implementation of each component was classified as high, medium or low according to set standards, and reported back at the end of each phase, allowing for improvements. The school and worksite components were implemented with high reach, dose delivered and fidelity, with improvement over time. The school program had only moderate reach and dose delivered, as did the social media component. The CAC achieved high reach and dose delivered. Overall, study reach and dose delivered reached a high implementation level, whereas fidelity was medium. Great challenges exist in the consistent implementation of MLMC interventions. The detailed process evaluation of the OPREVENT2 trial allowed us to carefully assess the relative strengths and limitations of each intervention component.

Abstract
The food environment is a critical place in the food system to implement interventions to support sustainable diets and address the global syndemic of obesity, undernutrition, and climate change, because it contains the total scope of options within which consumers make decisions about which foods to acquire and consume. In this paper, we build on existing definitions of the food environment, and provide an expanded definition that includes the parameter of sustainability properties of foods and beverages, in order to integrate linkages between food environments and sustainable diets. We further provide a graphical representation of the food environment using a socio-ecological framework. Next, we provide a typology with descriptions of the different types of food environments that consumers have access to in low-, middle-, and high-income countries including wild, cultivated, and built food environments. We characterize the availability, affordability, convenience, promotion and quality (previously termed desirability), and sustainability properties of food and beverages for each food environment type. Lastly, we identify a methodological approach with potential objective and subjective tools and metrics for measuring the different properties of various types of food environments. The definition, framework, typology, and methodological toolbox presented here are intended to facilitate scholars and practitioners to identify entry points in the food environment for implementing and evaluating interventions that support sustainable diets for enhancing human and planetary health.

Abstract
BACKGROUND A poor quality diet is a well-known risk factor for many chronic diseases. However, eating a healthful diet is not always simple as many underlying factors can impede adherence. Individuals with fewer barriers are more likely to eat a healthful diet than those who have more barriers. Accurately measuring barriers to eating a healthful diet could inform personalized interventions, particularly those aiming to prevent chronic diseases. The aim of this study was to establish content validity for selected items obtained from the National Health and Nutrition Examination Survey (NHANES) database to be considered for inclusion as items on the conceptualized Dietary Health Status (DHS) instrument, which is designed to measure barriers to eating a healthful diet in adults. METHODS The Behavioral Change Wheel hub COM-B and the Theoretical Domains Framework (TDF) were the two theoretical frameworks underpinning the development of the DHS instrument. Seven steps were conducted to create the instrument: 1) development of operational definitions for each TDF domain; 2) identification of items from the NHANES database 2011-2012; 3) screening of items to ensure inclusion of all relevant items; 4) assigning items to a theory-based domain; 5) evaluation of the items against inclusion/exclusion criteria; 6) solicitation of feedback from expert reviewers to reach consensus on inclusion into a domain; and 7) validation of items. RESULTS A total of 170 items representing twelve domains were identified as potential barriers to eating a healthful diet-- knowledge, optimism, beliefs about consequences, beliefs about capabilities, reinforcement, memory, attention and decision processes, environmental context and resources, social influences, emotion, behavioral regulation, health identity, and functional status. CONCLUSION Expert review consultation and a consensus approach established content validity for 12 theory-based domains comprised of 170 items identified as potential barriers to eating a healthful diet. The use of these explanatory domains may: assist researchers to better understand barriers to adult dietary practices; inform the development of a screening tool that could be used in a community setting to measure barriers to eating a healthful diet; and inform individualized interventions.

Abstract
BACKGROUND Due to their central position in the modern food system, food stores present a unique opportunity to promote healthy dietary behaviour. However, there is a lack of insight into the factors that impede or enhance the implementation of nutritional interventions in food stores. We applied a systems innovation and implementation science framework to the identification of such barriers and facilitators. METHODS We conducted a systematic literature review. A search string was developed to identify qualitative and quantitative articles on environmental nutritional interventions in the food store. Four databases were systematically searched for studies published between 2000 and 2018. Eligible publications described study designs or original studies, focused on stimulating healthier dietary behaviour through environmental changes in retail settings and contained information on the perceptions or experiences of retailers or interventionists regarding the implementation process of the intervention. Context-descriptive data was extracted and a quality assessment was performed. RESULTS We included 41 articles, of which the majority was conducted in the USA and involved single stores or a mix of single and multi-store organisations. We categorized barriers and facilitators into 18 themes, under five domains. In the 'outer setting' domain, most factors related to consumers' preferences and demands, and the challenge of establishing a supply of healthy products. In the 'inner setting' domain, these related to conflicting values regarding health promotion and commercial viability, store lay-out, (insufficient) knowledge and work capacity, and routines regarding waste avoidance and product stocking. In the 'actors' domain, no major themes were found. For the 'intervention 'domain', most related to intervention-context fit, money and resource provision, material quality, and the trade-offs between commercial costs and risks versus commercial and health benefits. For the 'process' domain, most factors related to continuous engagement and strong relationships. CONCLUSIONS This review provides a comprehensive overview of barriers and facilitators to be taken into account when implementing nutritional interventions in food stores. Furthermore, we propose a novel perspective on implementation as the alignment of intervention and retail interests, and a corresponding approach to intervention design which may help avoid barriers, and leverage facilitators.

B'more Healthy Corner Stores for Moms and Kids: Identifying Optimal Behavioral Economic Strategies to Increase WIC Redemptions in Small Urban Corner Stores. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2018; 16:ijerph16010064. [PMID: 30591654 PMCID: PMC6339089 DOI: 10.3390/ijerph16010064] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 11/15/2018] [Revised: 12/09/2018] [Accepted: 12/20/2018] [Indexed: 11/17/2022]
Abstract
Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) redemption rates have been declining in many low-income urban settings, potentially related to aspects of the food environment. B’more Healthy Corner Stores for Moms and Kids was a feasibility trial in Baltimore City that aimed to test multiple behavioral economic (BE) strategies in 10 corner stores (intervention = eight stores, comparison = two stores), to evaluate their influence on the stocking and redemptions of WIC foods. Tested strategies included in-person storeowner training, point of purchase promotion, product placement, and grouping of products in a display. All four strategies were feasible and implemented with high reach, dose delivered, and fidelity. Additionally, text messaging was found to be an acceptable form of intervention reinforcement for storeowners. Analyses to assess change in stocking of WIC foods, total sales of WIC foods, and sales of WIC foods to WIC clients, revealed consistent positive changes after implementation of the store owner training strategy, while changes after the implementation of other strategies were mixed. Furthermore, WIC food sales to WIC clients significantly increased after the simultaneous implementation of two strategies, compared to one (p > 0.05). Results suggest that store owner training was the most influential strategy and that the implementation of more BE strategies does not necessarily lead to proportional increases in stocking and sales. Selected BE strategies appear to be an effective way of increasing stocking and sales of WIC foods in small urban food stores.

Abstract
B'More Healthy Communities for Kids was a multi-level, multi-component obesity prevention intervention to improve access, demand and consumption of healthier foods and beverages in 28 low-income neighborhoods in Baltimore City, MD. Process evaluation assesses the implementation of an intervention and monitor progress. To the best of our knowledge, little detailed process data from multi-level obesity prevention trials have been published. Implementation of each intervention component (wholesaler, recreation center, carryout restaurant, corner store, policy and social media/text messaging) was classified as high, medium or low according to set standards. The wholesaler component achieved high implementation for reach, dose delivered and fidelity. Recreation center and carryout restaurant components achieved medium reach, dose delivered and fidelity. Corner stores achieved medium reach and dose delivered and high fidelity. The policy component achieved high reach and medium dose delivered and fidelity. Social media/text messaging achieved medium reach and high dose delivered and fidelity. Overall, study reach and dose delivered achieved a high implementation level, whereas fidelity achieved a medium level. Varying levels of implementation may have balanced the performance of an intervention component for each process evaluation construct. This detailed process evaluation of the B'More Healthy Communities for Kids allowed the assessment of implementation successes, failures and challenges of each intervention component.

Multilevel Structural Equation Modeling of Students' Dietary Intentions/Behaviors, BMI, and the Healthfulness of Convenience Stores. Nutrients 2018; 10:nu10111569. [PMID: 30360538 PMCID: PMC6266756 DOI: 10.3390/nu10111569] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/18/2018] [Revised: 10/17/2018] [Accepted: 10/20/2018] [Indexed: 11/16/2022] Open
Abstract
Background: When dietary behaviors are habitual, intentions are low, and environmental cues, such as the consumer food environment, might guide behavior. How might intentions to eat healthily and ultimately actual dietary behaviors, be influenced by the consumer food environment (including the availability and affordability of healthy foods) in convenience stores? This study will determine pathways between the healthfulness of convenience stores and college students’ dietary intentions/behaviors, and body mass index (BMI). Methods: Through multilevel structural equation modeling, a comparison was made of students’ healthful meal intentions (HMI); intake (fruits/vegetables, %kcal/fat, sugar-sweetened beverages (SSBs) and whole-grains); and measured BMI; as well as the healthfulness of convenience stores (fruits/vegetables availability/quality, healthy food availability/affordability). Data was collected on 1401 students and 41 convenience stores across 13 US college campuses. Results: Controlling for gender, HMI was negatively associated with SSBs (β = −0.859) and %kcal/fat (β = −1.057) and positively with whole-grains (β = 0.186) and fruits/vegetables intake (β = 0.267); %Kcal/fat was positively (β = 0.098) and fruits/vegetables intake (β = −0.055) negatively associated with BMI. Campus level, fruits/vegetables availability were positively associated to HMI (β = 0.214, β = 0.129) and directly/negatively to BMI (β = −2.657, β = −1.124). Conclusions: HMI modifies dietary behaviors, with energy from fat and fruit/vegetable intake the most predictive of weight. Availability of fruit/vegetables in convenience stores make it easier for young adults to eat well.

Harvey SA. Observe Before You Leap: Why Observation Provides Critical Insights for Formative Research and Intervention Design That You'll Never Get From Focus Groups, Interviews, or KAP Surveys. GLOBAL HEALTH: SCIENCE AND PRACTICE 2018; 6:299-316. [PMID: 29794000 PMCID: PMC6024634 DOI: 10.9745/ghsp-d-17-00328] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/19/2017] [Accepted: 02/06/2018] [Indexed: 12/12/2022]
Abstract
Four case studies show how observation can uncover issues critical to making a health intervention succeed or, sometimes, reveal reasons why it is likely to fail. Observation can be particularly valuable for interventions that depend on mechanical or clinical skills; service delivery processes; effects of the built environment; and habitual tasks that practitioners find difficult to articulate. Formative research is essential to designing both study instruments and interventions in global health. While formative research may employ many qualitative methods, focus group discussions and in-depth interviews are the most common. Observation is less common but can generate insights unlikely to emerge from any other method. This article presents 4 case studies in which observation revealed critical insights: corralling domestic poultry to reduce childhood diarrhea, promoting insecticide-treated bed nets (ITNs) to prevent malaria, evaluating skilled birth attendant competency to manage life-threatening obstetric and neonatal complications, and assessing community health worker (CHW) ability to use malaria rapid diagnostic tests (RDTs). Observation of Zambian CHWs to design malaria RDT training materials revealed a need for training on how to take finger-stick blood samples, a procedure second nature to many health workers but one that few CHWs had ever performed. In Lima, Peru, study participants reported keeping their birds corralled “all the time,” but observers frequently found them loose, a difference potentially explained by an alternative interpretation of the phrase “all the time” to mean “all the time (except at some specific seemingly obvious times).” In the Peruvian Amazon, observation revealed a potential limitation of bed net efficacy due to the built environment: In houses constructed on stilts, many people sleep directly on the floor, allowing mosquitoes to bite from below through gaps in the floorboards. Observation forms and checklists from each case study are included as supplemental files; these may serve as models for designing new observation guides. The case studies illustrate the value of observation to clearly understanding clinical practices and skills, details about how people carry out certain tasks, routine behaviors people would most likely not think to describe in an interview, and environmental barriers that must be overcome if an intervention is to succeed. Observation provides a way to triangulate for social desirability bias and to measure details that interview or focus group participants are unlikely to recognize, remember, or be able to describe with precision.

Examining the Feasibility of Healthy Minimum Stocking Standards for Small Food Stores. J Acad Nutr Diet 2018; 118:1655-1663.

Abstract
OBJECTIVE In response to recent national efforts to increase the availability of healthy food in small stores, we sought to understand the extent to which small food stores could implement the newly published Healthy Small Store Minimum Stocking Recommendations and reflect on the new US Department of Agriculture Food and Nutrition Service's final rule for stocking of staple foods for Supplemental Nutrition Assistance Program-approved retailers. DESIGN We collected qualitative and quantitative data from 57 small stores in four states (Arizona, Delaware, Minnesota, and North Carolina) that accepted Supplemental Nutrition Assistance Program but not Special Supplemental Nutrition Assistance Program for Women, Infants, and Children benefits. Data from semistructured, in-depth interviews with managers/owners were transcribed, coded, and analyzed. We collected quantitative store inventory data onsite and later performed descriptive analyses. RESULTS Store interviews revealed a reluctant willingness to stock healthy food and meet new recommendations. No stores met recommended fruit and vegetable stocking, although 79% carried at least one qualifying fruit and 74% carried at least one qualifying vegetable. Few stores met requirements for other food categories (ie, whole grains and low-fat dairy) with the exception of lean proteins, where stores carrying nuts or nut butter were more likely to meet the protein recommendation. Water and 100% juice were widely available and 68% met basic healthy beverage criteria. CONCLUSIONS In contrast to the inventory observed, most owners believed store stock met basic recommendations. Further, findings indicate that small stores are capable of stocking healthy products; however, technical and infrastructure support, as well as incentives, would facilitate shifts from staple to healthier staple foods. Retailers may need support to understand healthier product criteria and to drive consumer demand for new products.

The Impact of a Multi-Level Multi-Component Childhood Obesity Prevention Intervention on Healthy Food Availability, Sales, and Purchasing in a Low-Income Urban Area. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2017; 14:ijerph14111371.

Abstract
The multifactorial causes of obesity require multilevel and multicomponent solutions, but such combined strategies have not been tested to improve the community food environment. We evaluated the impact of a multilevel (operating at different levels of the food environment) multicomponent (interventions occurring at the same level) community intervention. The B’more Healthy Communities for Kids (BHCK) intervention worked at the wholesaler (n = 3), corner store (n = 50), carryout (n = 30), recreation center (n = 28), household (n = 365) levels to improve availability, purchasing, and consumption of healthier foods and beverages (low-sugar, low-fat) in low-income food desert predominantly African American zones in the city of Baltimore (MD, USA), ultimately intending to lead to decreased weight gain in children (not reported in this manuscript). For this paper, we focus on more proximal impacts on the food environment, and measure change in stocking, sales and purchase of promoted foods at the different levels of the food system in 14 intervention neighborhoods, as compared to 14 comparison neighborhoods. Sales of promoted products increased in wholesalers. Stocking of these products improved in corner stores, but not in carryouts, and we did not find any change in total sales. Children more exposed to the intervention increased their frequency of purchase of promoted products, although improvement was not seen for adult caregivers. A multilevel food environment intervention in a low-income urban setting improved aspects of the food system, leading to increased healthy food purchasing behavior in children.

Abstract
Peer-led interventions may be an effective means of addressing the childhood obesity epidemic; however, few studies have looked at the long-term sustainability of such programs. As part of a multilevel obesity prevention intervention, B'More Healthy Communities for Kids, 16 Baltimore college students were trained as youth-leaders (YLs) to deliver a skill-based nutrition curriculum to low-income African American children (10-14 years old). In April 2015, formative research was used to inform sustainability of the YL program in recreation centers. In-depth interviews were conducted with recreation center directors ( n = 4) and the YLs ( n = 16). Two focus groups were conducted with YLs ( n = 7) and community youth-advocates ( n = 10). Barriers to this program included difficulties with transportation, time constraints, and recruiting youth. Lessons learned indicated that improving trainings and incentives to youth were identified as essential strategies to foster continuity of the youth-led program and capacity building. High school students living close to the centers were identified as potential candidates to lead the program. Based on our findings, the initial intervention will be expanded into a sustainable model for implementation, using a train-the-trainer approach to empower community youth to be change agents of the food environment and role models.

Abstract
Structural change approaches—also known as policy and environmental changes—are becoming increasingly common in health promotion, yet our understanding of how to evaluate them is still limited. An exploratory scoping review of the literature was conducted to understand approaches and methods used to evaluate structural change interventions in health promotion and public health literature. Two analysts—along with health sciences librarian consultation—searched PubMed, Web of Science, and EMBASE for peer-reviewed U.S.-based, English language studies published between 2005 and 2016. Data were extracted on the use of evaluation frameworks, study designs, duration of evaluations, measurement levels, and measurement types. Forty-five articles were included for the review. Notably, the majority (73%) of studies did not report application of a specific evaluation framework. Studies used a wide range of designs, including process evaluations, quasi- or nonexperimental designs, and purely descriptive approaches. In addition, 15.6% of studies only measured outcomes at the individual level. Last, 60% of studies combined more than one measurement type (e.g., site observation + focus groups) to evaluate interventions. Future directions for evaluating structural change approaches to health promotion include more widespread use and reporting of evaluation frameworks, developing validated tools that measure structural change, and shifting the focus to health-directed approaches, including an expanded consideration for evaluation designs that address health inequities.

Abstract
Higher rates of obesity and obesity-related chronic disease are prevalent in communities where there is limited access to affordable, healthy food. The B'More Healthy Communities for Kids (BHCK) trial worked at multiple levels of the food environment including food wholesalers and corner stores to improve the surrounding community's access to healthy food. The objective of this article is to describe the development and implementation of BHCK's corner store and wholesaler interventions through formal process evaluation. Researchers evaluated each level of the intervention to assess reach, dose delivered, and fidelity. Corner store and wholesaler reach, dose delivered, and fidelity were measured by number of interactions, promotional materials distributed, and maintenance of study materials, respectively. Overall, the corner store implementation showed moderate reach, dose delivered, and high fidelity. The wholesaler intervention was implemented with high reach, dose, and fidelity. The program held 355 corner store interactive sessions and had 9,347 community member interactions, 21% of which were with children between the ages of 10 and 14 years. There was a 15% increase in corner store promoted food stocking during Wave 1 and a 17% increase during Wave 2. These findings demonstrate a successfully implemented food retailer intervention in a low-income urban setting.

Abstract
Innovative approaches are needed to impact obesity and other diet-related chronic diseases, including interventions at the environmental and policy levels. Such interventions are promising due to their wide reach. This article reports on 10 multilevel community trials that the present authors either led (n = 8) or played a substantial role in developing (n = 2) in low-income minority settings in the United States and other countries that test interventions to improve the food environment, support policy, and reduce the risk for developing obesity and other diet-related chronic diseases. All studies examined change from pre- to postintervention and included a comparison group. The results show the trials had consistent positive effects on consumer psychosocial factors, food purchasing, food preparation, and diet, and, in some instances, obesity. Recently, a multilevel, multicomponent intervention was implemented in the city of Baltimore that promises to impact obesity in children, and, potentially, diabetes and related chronic diseases among adults. Based on the results of these trials, this article offers a series of recommendations to contribute to the prevention of chronic disease in Mexico. Further work is needed to disseminate, expand, and sustain these initiatives at the city, state, and federal levels.

Abstract
This study adapted Photovoice methodology for younger participants to better understand the perceptions of urban African American youth on their food environments and diets. Youth (n = 17, ages 10-13 years) photographed and described, using novel narrative-based activities, the myriad places they regularly acquired "junk food" from environments saturated with such but differed in their assessments of the availability and desirability of more nutritious alternative foods. Youth often discussed specific foods as well as peers and adults in their lives as either entirely "healthy" or "unhealthy." This concrete thinking should be considered when designing messaging strategies to improve diets in similar populations. Overall, Photovoice is an engaging and effective method to engage youth in efforts to improve food environments and diets.

Abstract
Several intersectoral community approaches targeting childhood obesity (IACOs) have been launched in the Netherlands. Translation of these approaches into practice is however arduous and implementation. We therefore studied the implementation of five IACOs in the Netherlands for one-and-a-half years. IACO implementation was evaluated via an adapted version of the MIDI questionnaire, consisting of 18 theory-based constructs. A response rate of 62% was obtained. A hierarchical multivariate linear regression model was used to analyse our data; the final regression model predicted 65% of the variance in adherence. Higher levels of self-efficacy, being an implementer embedded in community B, and having more than 1 year of experience with IACO implementation were associated with higher degrees of adherence. Formal ratification of implementation by management and being prescribed a higher number of activities were related to lower degrees of adherence. We advise that, when designing implementation strategies, emphasis should be placed on the enhancement of professionals' self-efficacy, limitation of the number of activities prescribed and allocation of sufficient time to get acquainted and experienced with IACO implementation. Longitudinal studies are needed to further evaluate interaction between and change within critical determinants while progressing through the innovation process.

Abstract
Receptivity to strategies to improve the food environment by increasing access to healthier foods in small food stores is underexplored. We conducted 20 in-depth interviews with small storeowners of different ethnic backgrounds as part of a small-store intervention trial. Store owners perceived barriers and facilitators to purchase, stock, and promote healthy foods. Barriers mentioned included customer preferences for higher fat and sweeter taste and for lower prices; lower wholesaler availability of healthy food; and customers' lack of interest in health. Most store owners thought positively of taste tests, free samples, and communication interventions. However, they varied in terms of their expectations of the effect of these strategies on customers' healthy food purchases. The findings reported add to the limited data on motivating and working with small-store owners in low-income urban settings.

Abstract
OBJECTIVE To determine whether living in a food swamp (≥4 corner stores within 0·40 km (0·25 miles) of home) or a food desert (generally, no supermarket or access to healthy foods) is associated with consumption of snacks/desserts or fruits/vegetables, and if neighbourhood-level socio-economic status (SES) confounds relationships. DESIGN Cross-sectional. Assessments included diet (Youth/Adolescent FFQ, skewed dietary variables normalized) and measured height/weight (BMI-for-age percentiles/Z-scores calculated). A geographic information system geocoded home addresses and mapped food deserts/food swamps. Associations examined using multiple linear regression (MLR) models adjusting for age and BMI-for-age Z-score. SETTING Baltimore City, MD, USA. SUBJECTS Early adolescent girls (6th/7th grade, n 634; mean age 12·1 years; 90·7 % African American; 52·4 % overweight/obese), recruited from twenty-two urban, low-income schools. RESULTS Girls' consumption of fruit, vegetables and snacks/desserts: 1·2, 1·7 and 3·4 servings/d, respectively. Girls' food environment: 10·4 % food desert only, 19·1 % food swamp only, 16·1 % both food desert/swamp and 54·4 % neither food desert/swamp. Average median neighbourhood-level household income: $US 35 298. In MLR models, girls living in both food deserts/swamps consumed additional servings of snacks/desserts v. girls living in neither (β=0·13, P=0·029; 3·8 v. 3·2 servings/d). Specifically, girls living in food swamps consumed more snacks/desserts than girls who did not (β=0·16, P=0·003; 3·7 v. 3·1 servings/d), with no confounding effect of neighbourhood-level SES. No associations were identified with food deserts or consumption of fruits/vegetables. CONCLUSIONS Early adolescent girls living in food swamps consumed more snacks/desserts than girls not living in food swamps. Dietary interventions should consider the built environment/food access when addressing adolescent dietary behaviours.

Abstract
The causes of obesity worldwide are complex and multilevel, including changing food environments, physical activity levels, policies, and food production systems. This intricate context requires multilevel and multicomponent (MLMC) interventions to improve health outcomes. We conducted a literature review of MLMC interventions for obesity prevention and mitigation; 14 studies meeting search criteria were identified. We found examples of successes in preventing obesity, reducing overweight, improving healthful behaviors, and enhancing some psychosocial indicators. Of eight studies that reported health and behavioral results, five showed no significant impact and three showed reductions in obesity. Four studies showed significant improvement in dietary behavior, and five reported significant desirable effects in physical activity or screen time. Five studies reported psychosocial impacts, and three of these showed significant improvements. MLMC approaches show promising results, particularly when they are able to integrate components at the policy, community, and interpersonal levels.

Abstract
OBJECTIVE Social relationships can impact youths' eating and physical activity behaviours; however, the best strategies for intervening in the social environment are unknown. The objectives of the present study were to provide in-depth information on the social roles that youths' parents and friends play related to eating and physical activity behaviours and to explore the impact of other social relationships on youths' eating and physical activity behaviours. DESIGN Convergent parallel mixed-methods design. SETTING Low-income, African American, food desert neighbourhoods in Baltimore City, MD, USA. SUBJECTS Data were collected from 297 youths (53 % female, 91 % African American, mean age 12·3 (sd 1·5) years) using structured questionnaires and combined with in-depth interviews from thirty-eight youths (42 % female, 97 % African American, mean age 11·4 (sd 1·5) years) and ten parents (80 % female, 50 % single heads of house, 100 % African American). RESULTS Combined interpretation of the results found that parents and caregivers have multiple, dynamic roles influencing youths' eating and physical activity behaviours, such as creating health-promoting rules, managing the home food environment and serving as a role model for physical activity. Other social relationships have specific, but limited roles. For example, friends served as partners for physical activity, aunts provided exposure to novel food experiences, and teachers and doctors provided information related to eating and physical activity. CONCLUSIONS Obesity prevention programmes should consider minority youths' perceptions of social roles when designing interventions. Specifically, future research is needed to test the effectiveness of intervention strategies that enhance or expand the supportive roles played by social relationships.

Abstract
OBJECTIVE NutriBee was the first clinical nutrition intervention designed to bring the Institute of Medicine recommendations for 20 hours of experiential nutrition-themed learning to grades 4-7 into club and camp settings. We piloted NutriBee to assess acceptability and impact among early adolescents in diverse and disadvantaged communities in order to evaluate its future potential as a group medical nutrition intervention. METHODS Nine communities across Guam, Maryland, Michigan, and New Mexico representing South Pacific Island, American Indian, urban African American, recently immigrated Hispanic, and rural Caucasian ethnic groups piloted NutriBee in nonclinical settings (clubs, schools, camps). The 6 club and camp pilots administered consenting NutriBee participants a 41-question pre-post survey assessing impact on food selection and the psychosocial parameters of intentions, outcome expectations, self-efficacy, and knowledge. Process measures included dose, fidelity, and acceptability questions. RESULTS Pre- and postsurveys were completed by 170 of 179 (95%) consenting, eligible participants. Impact scores increased significantly (p < 0.001): Food selection behavior (+9.3%), intentions (+19.1%), outcome expectations (+15.1%), self-efficacy (+7.4%), and knowledge (+17.6%). Each pilot (n = 6) demonstrated significant (p < 0.001) impact, a mean dose delivered of 80% (16 hours) or higher, and an acceptability score of at least 74%. Girls participating in girl-only programs (n = 72) shared greater impact than girls in coed programs (n = 41; 13.6% vs. 10.4% mean score increase, p = 0.05). CONCLUSIONS NutriBee successfully extended the impact of an IOM-aligned intervention to club and camp settings to which clinicians can refer at-risk early adolescents.

Abstract
B'More Healthy Community for Kids (BHCK) is an ongoing multi-level intervention to prevent childhood obesity in African-American low-income neighborhoods in Baltimore city, MD. Although previous nutrition interventions involving peer mentoring of youth have been successful, there is a lack of studies evaluating the influence of cross-age peers within interventions targeting youth. This article evaluates the implementation of the BHCK intervention in recreation centers, and describes lessons learned. Sixteen youth leaders delivered bi-weekly, interactive sessions to 10- to 14-y olds. Dose, fidelity and reach are assessed, as is qualitative information regarding what worked well during sessions. Dose is operationalized as the number of interactive sessions, and taste tests, giveaways and handouts per session; fidelity as the number of youth leaders participating in the entire intervention and per session and reach as the number of interactions with the target population. Based on a priori set values, number of interactive sessions was high, and number of taste tests, giveaways and handouts was moderate to high (dose). The number of participating youth leaders was also high (fidelity). Of the 14 planned sessions, the intervention was implemented with high/moderate reach. Data suggest that working with cross-age peers is a promising nutritional intervention for recreation centers.

Abstract
This study assessed the impact of a youth-targeted multilevel nutrition intervention in Baltimore City. The study used a clustered randomized design in which 7 recreation centers and 21 corner stores received interventions and 7 additional recreation centers served as comparison. The 8-month intervention aimed to increase availability and selection of healthful foods through nutrition promotion and education using point-of purchase materials such as posters and flyers in stores and interactive sessions such as taste test and cooking demonstrations. Two hundred forty-two youth-caregiver dyads residing in low-income areas of Baltimore City recruited from recreation centers were surveyed at baseline using detailed instruments that contained questions about food-related psychosocial indicators (behavioral intentions, self-efficacy, outcome expectancies, and knowledge), healthful food purchasing and preparation methods, and anthropometric measures (height and weight). The Baltimore Healthy Eating Zones intervention was associated with reductions in youth body mass index percentile (p = .04). In subgroup analyses among overweight and obese girls, body mass index for age percentile decreased significantly in girls assigned to the intervention group (p = .03) and in girls with high exposure to the intervention (p = .013), as opposed to those in comparison or lower exposure groups. Intervention youth significantly improved food-related outcome expectancies (p = .02) and knowledge (p < .001). The study results suggest that the Baltimore Healthy Eating Zones multilevel intervention had a modest impact in reducing overweight or obesity among already overweight low-income African American youth living in an environment where healthful foods are less available. Additional studies are needed to determine the relative impact of health communications and environmental interventions in this population, both alone and in combination.

Healthy versus Unhealthy Suppliers in Food Desert Neighborhoods: A Network Analysis of Corner Stores' Food Supplier Networks. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2015; 12:15058-74. [PMID: 26633434 PMCID: PMC4690901 DOI: 10.3390/ijerph121214965] [Citation(s) in RCA: 18] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/19/2015] [Revised: 11/11/2015] [Accepted: 11/16/2015] [Indexed: 01/22/2023]
Abstract
Background: Products in corner stores may be affected by the network of suppliers from which storeowners procure food and beverages. To date, this supplier network has not been well characterized. Methods: Using network analysis, we examined the connections between corner stores (n = 24) in food deserts of Baltimore City (MD, USA) and their food/beverage suppliers (n = 42), to determine how different store and supplier characteristics correlated. Results: Food and beverage suppliers fell into two categories: Those providing primarily healthy foods/beverages (n = 15) in the healthy supplier network (HSN) and those providing primarily unhealthy food/beverages (n = 41) in the unhealthy supplier network (UHSN). Corner store connections to suppliers in the UHSN were nearly two times greater (t = 5.23, p < 0.001), and key suppliers in the UHSN core were more diverse, compared to the HSN. The UHSN was significantly more cohesive and densely connected, with corner stores sharing a greater number of the same unhealthy suppliers, compared to HSN, which was less cohesive and sparsely connected (t = 5.82; p < 0.001). Compared to African Americans, Asian and Hispanic corner storeowners had on average −1.53 (p < 0.001) fewer connections to suppliers in the HSN (p < 0.001). Conclusions: Our findings indicate clear differences between corner stores’ HSN and UHSN. Addressing ethnic/cultural differences of storeowners may also be important to consider.

Abstract
BACKGROUND Early adolescents perceive peers as credible and relatable. Peers therefore have a unique conduit to engage early adolescents in positive health behaviors through nutrition learning such as that recommended by the U.S. Institute of Medicine (IOM). PURPOSE We developed an online, peer leader component to an existing in-person preventive nutrition intervention called NutriBee. We reasoned that youth ages 13-18 could create intervention materials that could remain engaging, credible and relatable to younger peers ages 10-12 online. Peer leaders could potentially derive health benefits from their service-learning experience. METHODS From 2013-2014 youth could apply online to relate a personal interest to nutrition, an opportunity promoted at NutriBee pilot sites and through social media. The peer leaders with diverse backgrounds honed original ideas into tangible projects with the support of adult subject-matter experts chosen by the youth. Nutrition expertise was provided by NutriBee staff who then also converted the youth-invented projects from various media into an online curriculum. RESULTS 19 of 27 (70%) of selected youth from 12 states and diverse backgrounds, created an online curriculum comprising 10% of NutriBee's 20-hour intervention. All 19 online projects modeled 1 or more of NutriBee's 10 positive health behaviors; 8 evoked the chemosenses; 6 conveyed food texture; and 13 provided social context. Peer leaders perceived career advancement and service learning benefits. The dose, pedagogic approach, and project content align with the IOM recommendation. CONCLUSIONS Youth created intervention materials which communicate positive health behaviors online in ways peers can adopt. In a customarily sight-sound digital platform, youth leveraged the senses of smell, taste and touch and social context important for food selection. Peer leaders derived health benefit, as indirectly assessed by IOM criteria.

Abstract
Systems modeling represents an innovative approach for addressing the obesity epidemic at the community level. We developed an agent-based model of the Baltimore City food environment that permits us to assess the relative impact of different programs and policies, alone and in combination, and potential unexpected consequences. Based on this experience, and a review of literature, we have identified a set of principles, potential benefits, and challenges. Some of the key principles include the importance of early and multilevel engagement with the community prior to initiating model development and continued engagement and testing with community stakeholders. Important benefits include improving community stakeholder understanding of the system, testing of interventions before implementation, and identification of unexpected consequences. Challenges in these models include deciding on the most important, yet parsimonious factors to consider, how to model food source and food selection behavior in a realistic yet transferable manner, and identifying the appropriate outcomes and limitations of the model.

Abstract
This study explores food preparation behaviors, including types of food prepared, methods of preparation, and frequency of preparation of low-income urban African American youth ages 9-15 in Baltimore City (n = 289) and analyzes a potential association to diet quality as measured through Healthy Eating Index 2010 (HEI) scores. Overall, the youth prepared their own food 6.7 ± 0.33 times per week without significant differences between age groups or genders as measured through pairwise comparison of means. Cereal, noodles, and sandwiches were amongst the foods prepared most frequently. Linear regression analysis found youth food preparation frequency was not significantly associated with total HEI (p = 0.59), sodium (p = 0.58), empty calories (p = 0.96), or dairy scores (p = 0.12). Younger age was associated with higher total HEI scores (p = 0.012) and higher dairy scores (p = 0.01) and female gender was associated with higher total HEI scores (p = 0.03), higher sodium scores (p = 0.03), and lower dairy scores (p = 0.008).

Abstract
OBJECTIVE To understand environmental factors influencing the food-related habits of low-income urban African American adolescents. DESIGN Qualitative research was conducted between February and April, 2010, using in-depth interviews, focus groups, and direct observation. SETTING The study was conducted in low-income, predominantly African American neighborhoods of Baltimore City. PARTICIPANTS A total of 20 adolescents were interviewed in 18 in-depth interviews (n = 13) and 2 focus groups (n = 7). Participants were recruited from Baltimore City recreation centers and were eligible if they were African American and aged 10-16 years. PHENOMENON OF INTEREST The food-related habits of low-income, African American, urban adolescents and reported perceptions of their food environments. ANALYSIS Interviews were audio recorded, transcribed, coded, and analyzed for emerging themes. RESULTS Six thematic categories emerged and were organized into 4 environmental contexts: the neighborhood context (accessibility of food and safety of neighborhood), the school context (school food environment), the family context (family health history, role modeling, and monitoring) and the peer context (peer behaviors). CONCLUSIONS AND IMPLICATIONS Future efforts to reduce the obesity epidemic among low-income African American adolescents should address the social environment of the family; however, positive behavior change may not be sustainable without neighborhood or school food environment modifications.
