Multilevel Interventions Targeting Obesity: State of the Science and Future Directions.

A seminal report, released in 2001 by the Institute of Medicine, spurred research on the design, implementation, and evaluation of multilevel interventions targeting obesity and related behaviors. By addressing social and environmental factors that support positive health behavior change, interventions that include multiple levels of influence (e.g., individual, social, structural) aim to bolster effectiveness and, ultimately, public health impact. With more than 20 years of multilevel obesity intervention research to draw from, this review was informed by published reviews (n = 51) and identified intervention trials (n = 103), inclusive of all ages and countries, to elucidate key learnings about the state of the science. This review provides a critical appraisal of the scientific literature related to multilevel obesity interventions and includes a description of their effectiveness on adiposity outcomes and prominent characteristics (e.g., population, setting, levels). Key objectives for future research are recommended to advance innovations to improve population health and reduce obesity.

Consideration of nutrition and sustainability in public definitions of 'healthy' food: an analysis of submissions to the US FDA.

OBJECTIVE: To better understand how the public defines 'healthy' foods and to determine whether the public considers sustainability, implicitly and explicitly, in the context of healthy eating. DESIGN: We conducted a content analysis of public comments submitted to the US FDA in 2016 and 2017 in response to an invitation for feedback on use of the term 'healthy' on food labels. The analysis explored the ways in which commenters' definitions of 'healthy' aligned with the 2015-2020 Dietary Guidelines for Americans and whether their definitions considered sustainability. SETTING: The US Government's Regulations.gov website. PARTICIPANTS: All 1125 unique comments from individuals and organisations. RESULTS: Commenters' definitions of 'healthy' generally mirrored the recommendations that the Dietary Guidelines for Americans put forth to promote a 'healthy eating pattern'. Commenters emphasised the healthfulness of fruit, vegetables, whole grains, fish and other minimally processed foods and the need to limit added sugars, sodium, saturated and trans fats and other ingredients sometimes added during processing. One-third of comments (n 374) incorporated at least one dimension of sustainability, mainly the environmental dimension. Commenters who mentioned environmental considerations primarily expressed concerns about synthetic chemicals and genetic modification. Less than 20 % of comments discussed social or economic dimensions of sustainability, and less than 3 % of comments (n 30) used the word 'sustainability' explicitly. CONCLUSIONS: This novel analysis provides new information about the public's perceptions of 'healthy' foods relative to nutrition and sustainability considerations. The findings can be used to advance policy discussions regarding nutrition labelling and guidance.

A qualitative exploration of the health needs and goals of urban women to inform the tailoring and adaptation of Strong Hearts Healthy Communities: a community-based cardiovascular disease prevention intervention.

BACKGROUND: In the United States, cardiovascular diseases (CVD) are the leading cause of death and disability in women. CVD-modifiable risk factors, including poor diet quality and inadequate physical activity, can be addressed through evidence-based interventions (EBIs). Strong Hearts Healthy Communities (SHHC) is an EBI that has demonstrated effectiveness in reducing CVD risk and improving health outcomes among rural white women. The aims of this study were to understand the general health, diet, and physical activity-related needs and goals of women living in an urban community, to inform the tailoring and adaptation of the SHHC EBI to an urban setting and more diverse population. METHODS: Focus groups (FGs) were conducted with African American/Black and Hispanic/Latinx women in the Dallas metropolitan area who had a BMI ≥ 25 kg/m2 and engaged in ≤ 150 min per week of moderate physical activity. The data were coded using a team-based, deductive, and thematic analysis approach, that included multiple coders and in-depth discussions. RESULTS: Four FGs with a total of 18 participants (79% Black and 21% Latinx) were conducted, and three themes were developed: (1) participants had adequate knowledge and positive attitudes towards healthy living but faced many barriers to practicing healthy behaviors; (2) culturally-based beliefs and community practices exerted a strong influence on behaviors related to food and stress, revealing barriers to healthy eating and generational differences in stress and stress management; (3) participants desired a more individualized approach to nutrition and physical activity interventions that included familiar and enjoyable activities and social support centered around shared health goals. CONCLUSIONS: The SHHC intervention and similar health programs for Black/African American and Hispanic/Latinx women in urban settings should emphasize individualized nutrition and practical skills for healthy eating with accessible, familiar, and enjoyable exercises. Additionally, stress management strategies should be culturally and generationally sensitive and social support, whether through family, friends, or other program participants, should be based on shared health goals.

The role of the community café in addressing food security: Perceptions of managers and directors.

In the United States, the pay-what-you-can restaurant model (community cafes) is an increasingly popular approach to addressing food insecurity in local communities. We conducted semi-structured interviews (n = 13) with community café executive managers and directors to assess their perceptions of the role that their cafes play in addressing food security (FS). Analysis of interviews revealed two major areas of emphasis by participants. Filling an unoccupied space in the food security landscape. Interviewees regularly cited the goal of making meals available through a dependable schedule, convenient location, and welcoming atmosphere for guests to promote regular visits to the café, and they did so with an awareness of how their practices were shaped by perceived shortcomings in comparable services. In addition, guest agency and social aspects of the café as components of utilization, was another major area. Interviewees often regarded the opportunity of the food insecure guest to choose healthy options (i.e., nutritionally dense) over less healthful ones (i.e., calorically dense) from the menu as a critical component of their service. The social component of the café (e.g., community atmosphere, 'dining-out' experience) was another aspect of the café's function that promoted dignity for the guest which can lead to greater likelihood of return visits. Perceptions shared by participants of the café's role in addressing food security suggest that rather than simply adding to the available options of hunger relief services, the café model attempts to address many areas of concern, such as structural and cultural barriers, found in the traditional forms of charitable food provision.

Perspectives of Home-Based Child Care Providers in New Mexico on Barriers and Facilitators to Participating in the Child and Adult Care Food Program, 2021-2022.

This study examined New Mexico home-based child care provider perspectives (n = 75) on barriers to and facilitators of Child and Adult Care Food Program (CACFP) participation. Two thirds of the sample were Spanish speakers. Providers reported that CACFP reimbursement does not cover actual food costs and the time-and-effort costs of obtaining qualifying foods and completing required documentation. They noted that additional reimbursed meals are needed for children in care for extended hours and that linguistically competent CACFP sponsor staff facilitated their participation.

Urban-Rural Differences in School Districts' Local Wellness Policies and Policy Implementation Environments.

Higher rates of obesity in rural compared to urban districts suggest environmental differences that affect student health. This study examined urban-rural differences in districts' local wellness policies (LWPs) and LWP implementation environments. Cross-sectional data from two assessments in Texas were analyzed. In assessment one, each district's LWP was reviewed to see if 16 goals were included. In assessment two, an audit was conducted to identify the presence of a wellness plan (a document with recommendations for implementing LWPs), triennial LWP assessment, and school health advisory councils (SHACs) on the district website. Rural districts' LWPs had a smaller number of total goals (B = -2.281, p = 0.014), nutrition education goals (B = -0.654, p = 0.005), and other school-based activity goals (B = -0.675, p = 0.001) in their LWPs, compared to urban districts. Rural districts also had lower odds of having a wellness plan (OR = 0.520, 95% CI = 0.288-0.939), p = 0.030) and a SHAC (OR = 0.201, 95% CI = 0.113-0.357, p < 0.001) to support LWP implementation, compared to urban districts. More resources may be needed to create effective SHACs that can help develop and implement LWPs in rural areas. Important urban-rural differences exist in Texas LWPs and LWP implementation environments.

Diet Quality of Community Café Meals Among Guests With Food Insecurity.

OBJECTIVE: Compare the diet quality of a meal consumed at a community café (café meals), a pay-what-you-can restaurant, to a meal consumed for an equivalent eating occasion on the day before (comparison meal) by guests with food insecurity. METHODS: Dietary recalls were collected from café guests with food insecurity to determine the Healthy Eating Index-2020 (HEI-2020) total and component scores. Healthy Eating Index-2020 scores were compared between meals using paired-sample t tests and Wilcoxon signed-rank tests. RESULTS: Most participants (n = 40; 80% male; 42.5% Black) had very low food security (70.0%). Café meal had a higher HEI-2020 total score (46.7 ± 10.5 vs 34.4 ± 11.6; P < 0.001) and total vegetables (2.6 ± 2.0 vs 1.2 ± 1.7; P = 0.004), total fruits (2.1 ± 2.2 vs 0.6 ± 1.5; P < 0.001), whole fruits (1.6 ± 2.0 vs 0.3 ± 0.9; P < 0.001), and refined grains (7.8 ± 3.5 vs 3.9 ± 3.9; P < 0.001) scores than comparison meals. CONCLUSIONS AND IMPLICATIONS: The café meal had better diet quality than the comparison meal, suggesting its potential for improving diet quality among guests with food insecurity.

Household Food Sourcing Patterns and Their Associations With Food Insecurity in Appalachian Ohio.

BACKGROUND: Households experiencing food insecurity may use dynamic strategies to meet food needs. Yet, the relationship between household food sourcing behaviors and food security, particularly in rural settings, is understudied. OBJECTIVE: To identify food sourcing patterns and their associations with food insecurity among households in rural Appalachian Ohio during the COVID-19 pandemic. DESIGN: Survey data were collected from a cohort of households in Athens County, OH, in July 2020, October 2020, January 2021, and April 2021. PARTICIPANTS/SETTING: The sample included 663 households with household food sourcing and food security information for ≥1 survey wave. MAIN OUTCOME MEASURES: Household food sourcing patterns. Households reported the frequency with which they obtained food from various retailers and charitable sources, classified as supercenters, supermarkets, convenience stores, farmers markets, or charitable sources. STATISTICAL ANALYSES: Principal component analysis was used to identify food sourcing patterns. Linear mixed models were used to assess changes in food sourcing behaviors over the study period and to determine whether food sourcing behaviors differed according to food security status. RESULTS: Two patterns were identified: Convenience Stores and Charitable Food and Supermarkets and Farmers Markets, not Supercenters. Relative to July 2020, alignment of households' food sourcing behaviors with the Supermarkets and Farmers Markets, not Supercenters pattern was higher in October 2020 (ß .07, 95% CI .02 to .12) and alignment with the Convenience Stores and Charitable Food pattern was lower in April 2021 (ß -.06, 95% CI -.11 to -.02). Compared with food-secure households, food sourcing behaviors of food-insecure households were more closely aligned with the Convenience Stores and Charitable Food pattern (ß .07, 95% CI .00 to .13); no statistically significant difference in scores was observed for the Supermarkets and Farmers Markets, not Supercenters pattern (ß -.07, 95% CI -.15 to .02). CONCLUSIONS: These findings support efforts to increase access to healthy, affordable options at venues where food-insecure households may be likely to obtain food, such as convenience stores and charitable sources.

School-based intervention impacts availability of vegetables and beverages in participants' homes.

As rates of metabolic syndrome rise, children consume too few vegetables and too much added sugar. Because children tend to eat what is available at home, the home environment plays a key role in shaping dietary habits. This secondary analysis evaluated the effects of a school-based gardening, cooking, and nutrition education intervention (TX Sprouts) compared to control on the availability of vegetables, fruit juice, and sugar-sweetened beverages (SSBs) at home. In the TX Sprouts cluster-randomized trial, 16 schools were randomized to TX Sprouts (n = 8 schools) or control (n = 8 schools) for one academic year. All schools served predominately Hispanic families with low incomes. TX Sprouts built school gardens and taught 18 lessons to all 3rd-5th grade students at intervention schools. TX Sprouts also offered monthly caregiver lessons before and/or after school. Caregivers completed questionnaires pre and post, providing demographics and information about home availability of vegetables, fruit juice, and SSBs. Summary statistics were used to describe the sociodemographic characteristics of participants. Linear regression assessed the change in scores (pre to post) for the food/ beverage availability question. The model was adjusted for the caregiver's education, employment status, child's grade, and free or reduced-price lunch eligibility. The analytic sample included 895 participants. Compared to control, the intervention positively changed the home availability of targeted foods and beverages, largely by improving the availability of vegetables and vegetable juice. This study showed that a school gardening, nutrition, and cooking program delivered to elementary children may positively influence the home food environment.
