Identifying the effects of environmental and policy change interventions on healthy eating

Objectively-measured Environmental Support for Physical Activity, Healthy Eating, and Breastfeeding in the Rural United States: A Scoping Review to Inform Opportunities for Public Health Surveillance

The purpose of this scoping review was to identify objectively-measured environmental initiatives or features that impact physical activity (PA), healthy eating (HE), and/or breastfeeding practices among rural communities in the United States. A secondary aim was to assess measurement approaches for assessing rural environments and resources. Searches, informed by a scientific librarian, occurred from February to July 2020. Grey literature was identified using Google, Google Scholar, Google government pages, public health, federal nutrition assistance program, Cooperative Extension Services, and related webpages. Medline, PubMed, Web of Science, and Agricola academic databases were selected to identify peer-reviewed research. ProQuest Global was used to identify dissertation/thesis research. Inclusion criteria included: (1) focus on PA, HE, and/or breastfeeding; (2) environmental features assessed using objective measures; (3) specific to U.S. rural populations/contexts; and (4) English language. PA environment results (n=49) focused on initiatives in parks and recreational settings, streets or sidewalks, schools, trails and greenways, workplaces, and churches. HE environment results (n=84) focused on retail environments, schools/childcare settings, food assistance programs, local food producers, and hospital or healthcare settings. Breastfeeding environment results (n=11) focused on healthcare settings, workplace settings, and food retail settings. To measure PA, HE, and breastfeeding environments, audits, scans, and administrative data were mostly used. Results from this scoping review were used to create recommendations for environmental interventions related to PA, HE, and breastfeeding in under-resourced, rural communities. Researchers and practitioners can also use findings from this study to understand best practices for objectively measuring environmental resources in rural contexts.

Health- and Non-Health-Related Corporate Social Responsibility Statements in Top Selling Restaurant Chains in the U.S. Between 2012 and 2018: A Content Analysis

Introduction

The aim of this study was to understand the prevalence and content of corporate social responsibility statements in the top-selling chain restaurants between 2012 and 2018 to inform the ways restaurants can impact population health.

Methods

The study used a web scraping technique to abstract relevant text information (n=6,369 text sections that contained possible corporate social responsibility statements or thematically coded portions of the text section) from the archived web pages of the 96 top-selling chain restaurants. Content analysis was used to identify key themes in corporate social responsibility statements across restaurants and over time. All data were abstracted, and analyses were completed between November 2019 and November 2023.

Results

The majority of restaurants (68.8%) included a corporate social responsibility statement on their web pages between 2012 and 2018, and approximately half of the restaurants featured a health-related corporate social responsibility statement (51.0%). There were increases in corporate social responsibility statements by chain restaurants over the study period from 186 corporate social responsibility statements in 2012 to 1,218 corporate social responsibility statements in 2018, with most statements focused on philanthropy (37.1% of coded statements), community activities that were not health related (18.4% of coded statements), and sustainability initiatives (18.3% of coded statements). Only one quarter (24.4%) of these corporate social responsibility statements were health related, and many were vague in nature (only 28% of the eligible statements could be coded by theme).

Conclusions

There is a need for more actionable health-focused initiatives in the corporate social responsibility statements for chain restaurants. Public health initiatives that engage with the restaurant industry should work to promote corporate social responsibility statements that are in line with other collective positions around improving health and reducing diet-related disease.

Subjectively-measured Environmental Support for Physical Activity, Healthy Eating, and Breastfeeding in the Rural United States: A Scoping Review to Inform Opportunities for Public Health Surveillance

The purpose of this scoping review was to identify subjectively-measured environmental initiatives or factors that influence PA, HE, and/or breastfeeding practices within rural U.S. communities. Guided by a scientific research librarian, searches occurred February through July 2020. Grey literature searches spanned Google, Google Scholar, government pages, and public health, federal nutrition assistance program, Cooperative Extension Services, and related webpages. Four academic databases (Medline, PubMed, Web of Science, Agricola) were selected to identify peer-reviewed research and ProQuest Dissertations and Theses Global were used to identify dissertation research. Inclusion criteria included: (1) breastfeeding, HE, and/or PA focus; (2) environmental factors assessed using subjective measures; (3) specific to U.S. rural populations/contexts; and (4) English language. PA environment results focused on initiatives or factors in recreation (parks, playgrounds, facilities; n=54), street/sidewalk (n=44), or school (n=33) settings. PA environmental initiatives/factors included increasing transport/accessibility or addressing geographic disparities for recreation settings, improving/installing walkability features for streets/sidewalks, integrating PA into lessons, or improving PA equipment/spaces for school settings. HE environment results focused on initiatives in retail (n=65) and schools/childcare (n=33) settings. HE environment change initiatives/factors in retail settings included increasing the availability of fruits/vegetables in existing establishments or the prevalence of healthy food outlets. In schools, HE environmental initiatives/factors increased fruits/vegetables served and/or reduced unhealthy foods. Breastfeeding environment results focused on workplace settings (n=3). Breastfeeding environment initiatives/recommendations in workplaces included increasing compatibility for breastfeeding by addressing environmental and cultural barriers. Results from this scoping review were used to create recommendations to improve PA, HE, or breastfeeding environments in rural U.S. settings.

Restaurants as Environments for Healthy Eating: Factors That Contribute to Restaurant-Based Healthy Eating Program Adoption

Purpose. This study identified restaurant manager/owner factors that may contribute to adoption of a restaurant-based healthy eating program, Eat Fit. Findings may be used to engage restaurants in efforts to increase access to and availability of healthy foods, promote healthy food choices, and work toward improving diet and lowering obesity and chronic disease risk in the community. Methods. Cross-sectional survey data were collected from restaurant managers/owners interested in partnering with Eat Fit. Variables included restaurant manager/owner beliefs, perceived staff knowledge/skills, support, self-efficacy, outcome expectancies, and barriers and facilitators to implementation. Results. Forty-nine managers/owners participated. Most managers/owners held positive beliefs about offering healthy food items in restaurants (83.7%). Most agreed that restaurants could influence eating behaviors (83.7%) and that restaurants have a responsibility to offer healthy options (77.6%). Most managers/owners perceived high levels of support (83.7%) and were confident in their ability (95.9%) to implement the Eat Fit program. The most cited barriers were customer preference, ingredient availability, staff knowledge, and operational challenges. The most common reasons for involvement in the program were a desire to increase access to healthy food, to entice customers looking for healthier food, a belief that restaurants should offer healthy food, and opportunities to market through Eat Fit. Conclusions. This research contributes to knowledge about beliefs and perceptions of restaurant manager/owners. Efforts to engage restaurants should focus on benefits of offering healthy food and the role restaurants can play in promoting health. Furthermore, programs may benefit from enhanced restaurant staff training, customer-targeted marketing, and educational efforts.

A scoping review of policies to encourage breastfeeding, healthy eating, and physical activity among rural people and places in the United States

BACKGROUND

Rural U.S. residents experience a disproportionate burden of diet and physical activity (PA) related chronic disease compared to urban residents, due to resource and economic challenges. Diverse policy approaches for chronic disease prevention have been implemented to address barriers to breastfeeding, healthy eating, and PA. Therefore, the purpose of this paper is to describe policy supports for breastfeeding, healthy eating, and/or PA occurring in rural U.S. areas.

METHODS

A scoping review was conducted March-June 2020 to identify policy, systems, and environment change approaches occurring in the rural U.S. for breastfeeding, healthy eating, and PA. Search procedures were guided by the PRISMA-ScR, Arksey and O'Malley's work (2007), and a science librarian. Medline, PubMed, Web of Science, and Agricola were used to identify peer-reviewed research. ProQuest Dissertations and Theses A&I were used to identify dissertation research. Grey literature searches included Google, Google Scholar, government pages, and public health, federal nutrition assistance program, Cooperative Extension Services, and related webpages. Policy results are reported and inclusion criteria were: (1) breastfeeding, healthy eating, and/or PA focus; (2) about policy factors; (3) specific to U.S. rural populations/places; and (4) English language. Outcomes (study/source design, objective(s), methods/measurement, setting, population characteristics, behavioral focus, policy-specific results) were extracted into a standardized Excel document.

RESULTS

Results include 122 total sources: original research, with some sources referencing multiple behaviors, (n = 74 sources: 8 breastfeeding, 41 healthy eating, 42 PA), grey literature (n = 45 sources: 16 breastfeeding, 15 healthy eating, 27 PA), and graduate research (n = 3 sources: 1 breastfeeding, 2 healthy eating, 1 PA). Breastfeeding policy initiatives included policies or programs at hospitals, increasing access to resources, and improving culture or norms at workplaces. Healthy eating policy initiatives included increasing access to healthy foods, reducing financial burden, implementing programs, food assistance programs, and healthy food prescriptions at healthcare facilities. PA policy initiatives focused on Complete Streets, joint or shared use efforts, Safe Routes to Schools, master plans for greenways, trails, and/or transportation, school health plans, and childcare/school standards.

CONCLUSIONS

Results from this scoping review compile and offer commentary on existing policy solutions to improve breastfeeding, healthy eating, and/or PA in the rural U.S.

Associations between the objective and perceived food environment and eating behavior in relation to socioeconomic status among adults in peri-urban settings: results from the CIVISANO study in Flanders, Belgium

Obesity, a significant public health concern, disproportionately affects people with lower socioeconomic status (SES). Food environments have been identified as part of the causal chain of this disparity. This study investigated variations in the food environment across groups with different SES profiles residing in peri-urban municipal settings. In addition, it examined the association of the perceived and objective food environments with eating behaviour and assessed if these associations were moderated by SES. Utilizing GIS and survey data (n = 497, aged 25-65), results showed differences in the objective and perceived food environments based on SES. Respondents with higher SES perceived their food environments as better but resided farther from all food outlets compared to respondents with lower SES. However, there was no difference in outlet density or mRFEI between SES groups. SES moderated associations between the objective and perceived food environments and most eating behavior outcomes except fast food consumption frequency. For fruits and vegetables, SES moderated the association between neighborhood availability and consumption frequency (β0.23,CI0.03;0.49). Stratified analysis revealed a positive association for both lower (β0.15, CI0.03;0.27) and higher (β0.37, CI 0.12;0.63) SES groups. For snack foods, SES moderated the association between healthy outlet density and consumption frequency (β-0.60, CI-0.94; -0.23), showing statistical significance only for respondents with higher SES (β0.36,CI 0.18;0.55). Similarly, for sugar-sweetened beverages, a statistically significant interaction was observed between unhealthy outlet density in the 1000m buffer and consumption frequency (β 0.06, CI 0.02; 0.11). However, this association was only statistically significant for respondents with higher SES (β-0.02,CI -0.05;-0.0002). These results emphasize the significance of SES as a crucial element in comprehending the connection between the food environment and eating behaviour. Indicating the need for policymakers to take SES into account when implementing food environment interventions, particularly when focusing on the neighborhood food environment without considering residents' SES and their perceptions.

Health Promotion and Chronic Disease Prevention at the Workplace

The concept of workplace safety and health has focused largely on preventing accidents and on minimizing hazardous exposures. However, because workers spend a substantial part of their waking hours at the workplace, the potential to influence the health of a large proportion of the world's population through the workplace is enormous. The opportunities to carry out health promotion and chronic disease prevention activities at the workplace are countless, including (a) health screening; (b) tobacco cessation activities; (c) the promotion of healthy food choices and weight loss; (d) active breaks with physical exercise in terms of microexercise, enhancement of infrastructure to stimulate physical activity, and organization of work tasks to facilitate incidental physical activity; and (e) routine vaccinations. This review discusses the key factors necessary to implement health promotion and chronic disease prevention programs at the workplace (SWOLE model) and discusses the different foci and possibilities with respect to the differing nature of work for the blue- versus white-collar workforce.

Evaluation of an Environmental Nutrition Intervention at the 2018 Commonwealth Games

There has been an increasing expectation that the food provided for athletes at major competition events meets the specific dietary and performance needs of athletes. The aim of this study was to map the range of food service nutrition schemes that were implemented prior to and during a major competition event (2018 Commonwealth Games) and evaluate these schemes through staff training satisfaction, athlete feedback, and quality assurance checks. This study followed a case study design with nutrition schemes as follows: informing (nutrition labelling), enabling (staff training, nutrition service), and engineering (modification to menus and recipes). Overall, participants reported that they easily found items on the menu that met their nutritional/dietary needs. When asked how useful the schemes were in helping them to identify items that meet their needs, the majority of participants found the nutrition cards (n = 227, 71%) and serving staff (n = 212, 66%) 'useful/very useful'. 'Good/very good' ratings were received by >90% of respondents for speed of service, staff politeness, and knowledge of the menu. Participants (n = 316) who rated the nutrition staff as 'useful/very useful' gave a higher median rating for the menu. Past events have focused on the impact of a single component in the food environment; however, taking a whole systems approach resulted in more suitable food provision to meet the dietary needs of athletes.

Community Walks: a cluster randomized controlled trial of a multilevel physical activity intervention for low income public housing residents

BACKGROUND

Physical activity behavioral interventions to change individual-level drivers of activity, like motivation, attitudes, and self-efficacy, are often not sustained beyond the intervention period. Interventions at both environmental and individual levels might facilitate durable change. This community-based study seeks to test a multilevel, multicomponent intervention to increase moderate intensity physical activity among people with low incomes living in U.S. public housing developments, over a 2 year period.

METHODS

The study design is a prospective, cluster randomized controlled trial, with housing developments (n=12) as the units of randomization. In a four-group, factorial trial, we will compare an environmental intervention (E) alone (3 developments), an individual intervention (I) alone (3 developments), an environmental plus individual (E+I) intervention (3 developments), against an assessment only control group (3 developments). The environmental only intervention consists of community health workers leading walking groups and indoor activities, a walking advocacy program for residents, and provision of walking maps/signage. The individual only intervention consists of a 12-week automated telephone program to increase physical activity motivation and self-efficacy. All residents are invited to participate in the intervention activities being delivered at their development. The primary outcome is change in moderate intensity physical activity measured via an accelerometer-based device among an evaluation cohort (n=50 individuals at each of the 12 developments) from baseline to 24-month follow up. Mediation (e.g., neighborhood walkability, motivation) and moderation (e.g., neighborhood stress) of our interventions will be assessed. Lastly, we will interview key informants to assess factors from the Consolidated Framework for Implementation Research domains to inform future implementation.

DISCUSSION

We hypothesize participants living in developments in any of the three intervention groups (E only, I only, and E+I combined) will increase minutes of moderate intensity physical activity more than participants in control group developments. We expect delivery of an intervention package targeting environmental and social factors to become active, combined with the individual level intervention, will improve overall physical activity levels to recommended guidelines at the development level. If effective, this trial has the potential for implementation through other federal and state housing authorities.

How to enable healthier and more sustainable food practices in collective meal contexts: A scoping review

Collective meal contexts such as restaurants, cafeterias and canteens can help accelerate transitions to healthier and more sustainable diets. However, evidence from intervention studies on these contexts lacks integration. This scoping review aimed to map determinants of dietary change in collective meal contexts across multiple settings, interventions, target groups, and target behaviors. The review provided two main outcomes: (i) identifying intervention components to promote dietary change in collective meal contexts, based on the existing body of evidence; and (ii) classifying and integrating these intervention components into an overarching framework of behavior change (i.e., COM-B system). The review encompassed twenty-eight databases via two indexing services and extracted information from 232 primary sources (27,458 records selected for title and abstract screening, 574 articles selected for full-text screening). We identified a total of 653 intervention activities, which were classified into intervention components and grouped under three broad themes, namely contextual and environmental changes, social influence, and knowledge and behavioral regulation. Multi-component interventions tended to report overall positive outcomes. The review proposes several directions for future research, including: (i) moving toward more theory-based interventions in collective meal contexts; (ii) providing more detailed information about intervention settings, implementation, target groups, activities, and materials; and (iii) improving the use of open science practices in the field. Furthermore, the review offers a free, original, open-access list and synthesis of 277 intervention studies in collective meal contexts, which can help intervention planners and evaluators optimize their efforts to promote healthier and more sustainable food practices in these contexts.

Life in lockdown: a qualitative study exploring the experience of living through the initial COVID-19 lockdown in the UK and its impact on diet, physical activity and mental health

BACKGROUND

In response to the COVID-19 pandemic, the UK imposed a national lockdown prompting change to daily routines. Among behaviours impacted by the lockdown, diet and physical activity may be particularly important due to their association with mental health and physical health. The aim of this study was to explore people's experiences of how lockdown impacted their physical activity, dietary behaviours and mental health, with a view to informing public health promotion.

METHODS

This phenomenological qualitative study used semi-structured telephone interviews. Interviews were audio-recorded and transcribed verbatim. Thematic analysis was conducted, guided by the Framework Approach.

RESULTS

Forty participants (28 female) completed an interview (mean duration: 36 min) between May and July 2020. The overarching themes identified were (i) Disruption (loss of routines, social interaction and cues to physical activity) and (ii) Adaptation (structuring the day, accessing the outdoor environment, finding new ways for social support). The disruption to daily routines altered people's cues for physical activity and eating; some participants spoke of comfort eating and increased alcohol intake in the early days of lockdown, and how they consciously tried to change these when restrictions lasted longer than first anticipated. Others spoke of adapting to the restrictions using food preparation and meals to provide both routine and social time for families. Disruptions from the closure of workplaces resulted in flexible working times for some, allowing for physical activity to be built into the day. In later stages of restrictions, physical activity became an opportunity for social interaction and several participants reported intending to continue to replace sedentary means of socialising (e.g., meeting in cafes) with more active, outdoor activities (e.g., walking) once restrictions were lifted. Staying active and building activity into the day was seen as important to support physical and mental health during the challenging times of the pandemic.

CONCLUSIONS

Whilst many participants found the UK lockdown challenging, adaptations to cope with the restrictions presented some positive changes related to physical activity and diet behaviours. Helping people sustain their new healthier activities since restrictions have lifted is a challenge but presents an opportunity for public health promotion.

A qualitative exploration of English black adults’ views of strength and balance activities in mid-life

Background

Public health guidelines state that all adults should undertake muscle and bone strengthening and balance training activities at least twice a week to support their physical function and maintain independent health. This is intended to maintain strength in adulthood and offset natural declines in bone density and muscle mass. Most older adults do not meet this guideline with low levels of compliance among older black people. This study explored the experiences of physical activity relating to strength and balance activities, amongst black men and women living in England, aged 50–70.

Methods

Participants were recruited by phone via a network of research recruitment specialists across England. In-depth qualitative interviews were conducted with 25 black people aged 50–70 living in England. An inductive thematic analysis was conducted.

Results

We found there was only a very general understanding of the importance of maintaining body strength and balance, and low salience: strength and balance activities were not seen to be an important part of participants’ lives. Most participants only wanted to be strong enough to get on with ‘normal life’ and not to build strength or balance. Participants aged 50–70 were likely to think they were too young to worry about strength and balance, which tended to be mentioned only if someone had experienced a problem. Participants reported that NHS staff, especially physiotherapists are a key source of information on the topic and could therefore be useful in future prevention strategies.

Conclusion

Public health recommendations stress the importance of increasing participation in regular strength and balance activities as people age, to reduce the risk of falls and maintain independence. This study has shown that among the black middle-aged adults we interviewed, the knowledge and salience of this message is low. Public health approaches should be taken to communicate the importance of enhancing strength and balance as people approach older age, including communication and education programmes led by health professionals, who were viewed with authority amongst these participants.

Community–Clinical Linkages: The Effects of the Healthy Here Wellness Referral Center on Chronic Disease Indicators Among Underserved Populations in New Mexico

The majority of U.S. adults are living with at least one chronic condition, and people of color bear a disproportionate burden of chronic disease. Prior research identifies community–clinical linkages (CCLs) as a strategy for improving health. CCLs traditionally use health care providers to connect patients to community-based self-management programs. The purpose of this study was to examine the effectiveness of a centralized CCL system on health indicators and health disparities. Administrative health data were merged with referral system data to conduct a quasi-experimental comparative time series study with a comparison group of nonreferred patients. Interrupted time-series comparisons within referred patients were also conducted. Of the 2,920 patients meeting inclusion criteria, 972 (33.3%) received a referral during the study period (January 2019—September 2021). Hemoglobin A1c levels, used to diagnose diabetes, declined significantly among referred patients, as did disparities among Hispanic/Latinx participants compared with non-Hispanic White participants. No changes were observed in body mass index (BMI). Blood pressure increased among both referred and nonreferred patients. CCLs with a centralized referral system can effectively reduce markers of diabetes and may contribute to the maintenance of BMI. The observed increase in blood pressure may have been affected by the COVID-19 pandemic and warrants further study. Practitioners can work with community partners to implement a centralized CCL model, either on its own or to enhance existing clinician or community health worker-based models.

Does an active play standard change childcare physical activity and healthy eating policies? A natural policy experiment

Background

In 2017, the provincial government of British Columbia (BC) implemented a mandatory policy outlining Active Play Standards (AP Standards) to increase physical activity (PA) levels, sedentary and motor skills among children attending licensed childcare centers. Concurrently, a capacity-building initiative was launched to help implement policies and practices supporting both PA and healthy eating (HE) in the early years. This study evaluated differences in center-level PA and HE policies and practices before and after the enforcement of the new provincial AP Standards.

Methods

Using a repeat cross-sectional design, surveys were distributed to managers and staff of licensed childcare facilities serving children aged 2–5 years before (2016–2017 or ‘time 1’) and after (2018–2019 or ‘time 2’) implementation of the AP Standards across BC. The total sample included 1,459 respondents (910 and 549 respondents at time 1 and time 2, respectively). Hierarchical mixed effects models were used to examine differences in 9 and 7 PA/sedentary policies and practices, respectively, as well as 11 HE policies between time 1 and time 2. Models controlled for childcare size and area-level population size, education, and income.

Results

Compared to centers surveyed at time 1, centers at time 2 were more likely to report written policies related to: fundamental movement skills, total amount of Active Play (AP) time, staff-led AP, unfacilitated play/free play, total amount of outdoor AP time, limiting screen time, breaking up prolonged sitting, staff role modeling of PA, and training staff about PA (P < 0.01 for all 9 policies examined). Compared to time 1, centers at time 2 reported more frequent practices related to ensuring children engaged in at least 120 min of AP, 60 min of outdoor AP daily, and limiting screen time (P < 0.01 for 3 out of 7 practices examined). Despite no additional policy intervention related to HE, centers were more likely to report having written policies related to: HE education for children, encouraging new foods, having family-style meals, offering only milk or water, limiting the amount of juice served, staff role modeling of HE, limiting the types of foods at parties/celebrations and foods brought from home (P < 0.05 for 9 out of 11 HE policies).

Conclusion

Approximately a year after the implementation of a governmental policy targeting PA supported by a capacity-building initiative, childcare centers reported positive changes in all 9 PA/sedentary policies examined, all 3 out of 7 PA/sedentary practices and 9 out of 11 HE policies evaluated at the center-level.

Exploring the Impact of Policies to Improve Geographic and Economic Access to Vegetables among Low-Income, Predominantly Latino Urban Residents: An Agent-Based Model

Modifying the food environment of cities is a promising strategy for improving dietary behaviors, but using traditional empirical methods to test the effectiveness of these strategies remains challenging. We developed an agent-based model to simulate the food environment of Austin, Texas, USA, and to test the impact of different food access policies on vegetable consumption among low-income, predominantly Latino residents. The model was developed and calibrated using empirical data from the FRESH-Austin Study, a natural experiment. We simulated five policy scenarios: (1) business as usual; (2)−(4) expanding geographic and/or economic healthy food access via the Fresh for Less program (i.e., through farm stands, mobile markets, and healthy corner stores); and (5) expanding economic access to vegetables in supermarkets and small grocers. The model predicted that increasing geographic and/or economic access to healthy corner stores will not meaningfully improve vegetable intake, whilst implementing high discounts (>85%) on the cost of vegetables, or jointly increasing geographic and economic access to mobile markets or farm stands, will increase vegetable intake among low-income groups. Implementing discounts at supermarkets and small grocers is also predicted to be an effective policy for increasing vegetable consumption. This work highlights the utility of agent-based modeling for informing food access policies.

Longitudinal associations between objective and perceived healthy food environment and diet: The Multi-Ethnic Study of Atherosclerosis

INTRODUCTION

Research examining the influence of neighborhood healthy food environment on diet has been mostly cross-sectional and has lacked robust characterization of the food environment. We examined longitudinal associations between features of the local food environment and healthy diet, and whether associations were modified by race/ethnicity.

METHODS

Data on 3634 adults aged 45-84 followed for 10 years were obtained from the Multi-Ethnic Study of Atherosclerosis. Diet quality was assessed using the Alternative Healthy Eating Index at Exam 1 (2000-2002) and Exam 5 (2010-2012). We assessed four measures of the local food environment using survey-based measures (e.g. perceptions of healthier food availability) and geographic information system (GIS)-based measures (e.g. distance to and density of healthier food stores) at Exam 1 and Exam 5. Random effects models adjusted for age, sex, education, moving status, per capita adjusted income, and neighborhood socioeconomic status, and used interaction terms to assess effect measure modification by race/ethnicity.

RESULTS

Net of confounders, one standard z-score higher average composite local food environment was associated with higher average AHEI diet score (β=1.39, 95% CI: 1.05, 1.73) over the follow-up period from Exam 1 to 5. This pattern of association was consistent across both GIS-based and survey-based measures of local food environment and was more pronounced among minoritized racial/ethnic groups. There was no association between changes in neighborhood environment and change in AHEI score, or effect measure modification by race/ethnicity.

CONCLUSION

Our findings suggest that neighborhood-level food environment is associated with better diet quality, especially among racially/ethnically minoritized populations.

Behavioural change box? Applying the COM-B model to understand behavioural triggers that support consumption of fruits and vegetable among subscribers of a fruit and vegetable box scheme

OBJECTIVE

To understand the key mechanisms that support healthy dietary habits promoted by fruit and vegetable (F&V) box schemes, testing relevant behaviour change triggers identified under the COM-B model in an evaluation research study of a Portuguese F&V box scheme (PROVE).

DESIGN

Correlation study with a post-test-only non-equivalent group design based on survey data. The mechanisms underpinning the differences between subscribers and non-subscribers are operationalised as mediation effects. Data availability, theoretical relevance and empirical validation supported the selection and testing of four potential mediators for the effects of subscribing to the box scheme on F&V consumption. These estimations derive from the coefficients of a structural equation model combined with the product coefficient approach and Sobel test.

SETTING

The study is part of a wider evaluation study on the impact of the PROVE box scheme on sustainability, health and equity.

PARTICIPANTS

A sample of PROVE box subscribers (n 294) was compared with a matched subsample of non-subscribers (n 571) in a nationally representative survey.

RESULTS

Subscribing to the PROVE box correlates with an increased probability of eating at least five portions of F&V, irrespective of differences in age, education and perceived economic difficulties. Diet quality perceptions, and more robustly, the strength of meal habits and household availability were identified as relevant mediators.

CONCLUSIONS

The subscription to an F&V box scheme is connected with proximal context that enables the consumption of F&V by ensuring more readily available F&V and better situational conditions associated with healthier meal habits.

Toward a Healthy and Environmentally Sustainable Campus Food Environment: A Scoping Review of Postsecondary Food Interventions

Interventions are urgently needed to transform the food system and shift population eating patterns toward those consistent with human health and environmental sustainability. Postsecondary campuses offer a naturalistic setting to trial interventions to improve the health of students and provide insight into interventions that could be scaled up in other settings. However, the current state of the evidence on interventions to support healthy and environmentally sustainable eating within postsecondary settings is not well understood. A scoping review of food- and nutrition-related interventions implemented and evaluated on postsecondary campuses was conducted to determine the extent to which they integrate considerations related to human health and/or environmental sustainability, as well as to synthesize the nature and effectiveness of interventions and to identify knowledge gaps in the literature. MEDLINE (via PubMed), CINAHL, Scopus, and ERIC were searched to identify articles describing naturalistic campus food interventions published in English from January 2015 to December 2019. Data were extracted from 38 peer-reviewed articles, representing 37 unique interventions, and synthesized according to policy domains within the World Cancer Research Foundation's NOURISHING framework. Most interventions were focused on supporting human health, whereas considerations related to environmental sustainability were minimal. Interventions to support human health primarily sought to increase nutrition knowledge or to make complementary shifts in food environments, such as through nutrition labeling at point of purchase. Interventions to support environmental sustainability often focused on reducing food waste and few emphasized consumption patterns with lower environmental impacts. The implementation of integrated approaches considering the complexity and interconnectivity of human and planetary health is needed. Such approaches must go beyond the individual to alter the structural determinants that shape our food system and eating patterns.

Development and piloting of a Checklist for healthy eating And Physical Activity in the Workplace (CEPAW)

To develop and pilot a tool that assesses the infrastructure and policy workplace environment characteristics that may influence employee healthy eating and physical activity behaviours. A checklist was developed with reference to prior tools and piloted at eight worksites. Piloting of the tool demonstrated that it was generally feasible to use, took 1-2 hours to complete and appeared sensitive to differences between workplace environment characteristics. Refinement of the tool occurred after piloting. The final 21-item checklist contains sub-scores capturing policy, infrastructure, healthy eating and physical activity characteristics. This new checklist overcomes some limitations of pre-existing tools as it explicitly considers policy and is short, inexpensive and can be used by workplaces for self-assessment and by health promotion professionals in evaluation studies or as an intervention tool.

Explaining inequalities in fruit and vegetable intake in Europe: The role of capabilities, opportunities and motivations

People who do not eat enough fruit and vegetables (F&V) have incremental health risks. Most Europeans do not comply with health recommendations relating to F&V consumption and this is especially true for those with lower-level education, which reinforces structural inequalities in health and wellbeing among Europeans. This study investigated the role of key behavioural triggers - capabilities, opportunities and motivation (in the COM-B model) - as pathways for educational differentials in F&V intake in Europe. A cross-sectional survey-based study was conducted in five European countries differing widely in their consumption habits, wealth, and climatic conditions. A structural equation model was designed to study how capabilities (diet perceived knowledge, health purchase criteria), opportunities (financial availability, social norms), and motivations (health value, habits strength) affect educational inequalities in the intake of F&V (5 portions a day) as mediators. Multi-group comparisons assessed country differences. People with higher levels of education were more likely to eat the recommended diet, i.e., at least 5 portions of F&V a day. Countries in the sample vary significantly in the percentage of people complying with the recommendation, but not significantly in terms of relative education differentials. The educational gap in the intake of F&V is mainly explained by education differentials in financial availability, diet knowledge, and habits in inserting F&V in main meals. Policies targeting dietary inequalities should address behavioural triggers affecting dietary intake, for example by subsidising F&V, developing targeted dietary awareness campaigns, or by intervening in mass catering contexts to facilitate the implementation of healthy habits.

Planting seeds of change: reconceptualizing what people eat as eating practices and patterns

Language focused on individual dietary behaviors, or alternatively, lifestyle choices or decisions, suggests that what people eat and drink is primarily a choice that comes down to free will. Referring to and intervening upon food consumption as though it were a freely chosen behavior has an inherently logical appeal due to its simplicity and easily defined targets of intervention. However, despite decades of behavioral interventions, population-level patterns of food consumption remain suboptimal. This debate paper interrogates the manner in which language frames how problems related to poor diet quality are understood and addressed within society. We argue that referring to food consumption as a behavior conveys the idea that it is primarily a freely chosen act that can be ameliorated through imploring and educating individuals to make better selections. Leveraging practice theory, we subsequently propose that using the alternative language of eating practices and patterns better conveys the socially situated nature of food consumption. This language may therefore point to novel avenues for intervention beyond educating and motivating individuals to eat more healthfully, to instead focus on creating supportive contexts that enable sustained positive dietary change. Clearly, shifting discourse will not on its own transform the science and practice of nutrition. Nevertheless, the seeds of change may lie in aligning our terminology, and thus, our framing, with desired solutions.

Socioeconomic inequalities in effectiveness of and compliance to workplace health promotion programs: an individual participant data (IPD) meta-analysis

BACKGROUND

This individual patient data (IPD) meta-analysis aimed to investigate socioeconomic inequalities in effectiveness on healthy behavior of, and compliance to, workplace health promotion programs.

METHODS

Dutch (randomized) controlled trials were identified and original IPD were retrieved and harmonized. A two-stage meta-analysis was conducted where linear mixed models were performed per study (stage 1), after which individual study effects were pooled (stage 2). All models were adjusted for baseline values of the outcomes, age and gender. Intervention effects were assessed on physical activity, diet, alcohol use, and smoking. Also, we assessed whether effects differed between participants with low and high program compliance and. All analyses were stratified by socioeconomic position.

RESULTS

Data from 15 studies (n = 8709) were harmonized. Except for fruit intake (beta: 0·12 [95% CI 0·08 0·15]), no effects were found on health behaviors, nor did these effects differ across socioeconomic groups. Only participants with high compliance showed significant improvements in vigorous and moderate-to-vigorous physical activity, and in more fruit and less snack intake. There were no differences in compliance across socioeconomic groups.

CONCLUSIONS

Workplace health promotion programs were in general not effective. Neither effectiveness nor compliance differed across socioeconomic groups (operationalized by educational level). Even though stronger effects on health behavior were found for participations with high compliance, effects remained small. The results of the current study emphasize the need for new directions in health promotion programs to improve healthy behavior among workers, in particular for those in lower socioeconomic position.

Healthy Eating Policy Improves Children's Diet Quality in Early Care and Education in South Carolina

Policies to promote healthy foods in early care and education (ECE) in the United States exist, but few have been prospectively evaluated. In South Carolina, a statewide program serving low-income children in ECE enacted new policies promoting healthy foods. We conducted an evaluation to measure changes in dietary intake among children in ECE exposed and not exposed to the new policy. Using direct observation, we assessed dietary intake in 112 children from 34 ECE centers in South Carolina and 90 children from 30 ECE centers in North Carolina (a state with no policy). We calculated Healthy Eating Index-2015 (HEI) scores to measure diet quality consumed before and after the policy was enacted. We fit mixed-effects linear models to estimate differences in HEI scores by state from baseline to post-policy, adjusting for child race, number of children enrolled, director education, center years in operation, participation in the Child and Adult Care Food Program (CACFP), and center profit status. The policy increased HEI scores for whole fruits, total fruits, and lean proteins, but decreased scores for dairy. Thus, the policy was associated with some enhancements in dietary intake, but additional support may help improve other components of diet.

Effects of a food hub initiative in a disadvantaged community: A quasi-experimental evaluation

A quasi-experiment evaluated a food hub's (FH) impact in a low-income/low-access (food desert) setting on fruit and vegetable (F&V) intake, diet quality, kilocalories, perceived food environment, BMI, and farmers' market shopping versus a matched community (n = 265 FH, n = 262 Comparison). Comparison shoppers had better baseline perceptions of their food environment, but FH shoppers improved significantly more than Comparison shoppers. Comparison shoppers significantly increased F&V intake versus FH shoppers. Effects were not significant for other diet outcomes, BMI, or farmers' market shopping. Factors besides spacial access to healthy food need consideration to address dietary intake and obesity in disadvantaged communities.

Long-term effect of the Brazilian Workers' Food Program on the nutritional status of manufacturing workers: A population-based prospective cohort study

Background

The Brazilian Workers Food Program (WFP) is a public policy program of nutritional assistance to workers, with the main objective of improving nutritional conditions, which was implemented 40 years ago and serves over 21.4 million workers.

Objectives

To compare the long-term change in anthropometric indicators of the nutritional status and dietary intake between workers of manufacturing industries adherent to and non-adherent to the WFP.

Methods

A prospective cohort study, based on a combined stratified and multistage probability sampling, was carried out, with two waves with a 4-year interval. The change in body mass index (BMI), waist circumference (WC) and dietary intake at lunch by the 24-hour recall method were compared between groups with analysis of covariance.

Results

A total of 273 workers in 16 industries from an initial cohort of 1069 workers in 26 industries of the State of Rio Grande do Norte in Brazil were evaluated in the two waves. The mean age was 37±10 years and 53.1% were male, with no differences between groups in age and sex distribution. BMI increased in both groups (0.44 kg/m2 in non-WFP, p = 0.003, and 0.56 kg/m2 in WFP, p = 0.0006) and WC increased in the WFP group (1.50 cm, p = 0.0006). BMI change over time did not show statistical differences between groups (p = 0.54) but WC had a greater increase in the WFP group (difference 1.37 cm, p = 0.047). There were no differences between groups in the change over time of the dietary intake.

Conclusion

BMI and WC increased over time in manufacturing workers of industries both adherent and non-adherent to the WFP, but with a greater increase of WC in the WFP group. In order to achieve the objectives of the WFP, there will be a need for periodic evaluation and monitoring of nutritional indicators in these workers and implementation of monitoring and enforcement actions of the WFP.

Neighborhood Food Outlet Access and Dietary Intake among Adults with Chronic Kidney Disease: Results from the Chronic Renal Insufficiency Cohort Study

BACKGROUND

Healthy diet is essential in the management of chronic kidney disease (CKD) and preventing related comorbidities. Food outlet access has been studied in the general population; however, the influence of the local food environment on dietary intake among people with CKD has not been evaluated.

OBJECTIVES

This study examined the associations of food outlet density and type of outlets with dietary intake in a multicenter cohort of racially and ethnically diverse patients with CKD.

METHODS

The Chronic Renal Insufficiency Cohort Study is a multicenter prospective study of patients with CKD that used a validated food frequency questionnaire to capture dietary intake at the baseline visit. This is a cross-sectional analysis of 2,484 participants recruited in 2003-2006 from seven Chronic Renal Insufficiency Cohort Study centers. Food outlet data were used to construct a count of the number of fast-food restaurants, convenience stores, and grocery stores per 10,000 population for each geocoded census block group. Multivariable linear and logistic regression models were used to evaluate the associations between measures of food outlet availability and dietary factors.

RESULTS

The proportion of participants living in zero-, low-, and high-food outlet density areas differed by gender, race or ethnicity, and income level. Among male subjects, living in areas with zero or the highest number of outlets was associated with having the highest caloric intakes in multivariable models. Male subjects living in areas with zero outlets consumed the highest levels of sodium and phosphorous. Female subjects living in areas with zero outlets had the lowest average intake of calories, sodium, and phosphorous. Among low-income female subjects, close proximity to more outlets was associated with higher calorie consumption. Among all participants, access to fast-food restaurants was not associated with an unhealthy diet score, and access to grocery stores was not associated with a healthy diet score.

CONCLUSIONS

Average caloric and nutrient intakes differed by outlet availability; however, there were no strong associations with type of food outlet. This should be considered when developing food-focused public health policies.

Impact of Dining Hall Structural Changes on Food Choices: A Pre-Post Observational Study

Change that benefits individuals and organisations while delivering health outcomes and benefits society requires a research focus that extends ‘beyond the individual’ to environment shapers. A pre-post observational study assessed two food provision structural changes to understand the role food service environments had on food selections. Diners were observed prior to (lunch n = 1294; dinner n = 787) and following (lunch n = 1230; dinner n = 843) structural changes in a buffet-style dining room—including provision of a healthy convenient meal alternative for lunch (healthy lunch bag), and a pleasurable dinner (make-your-own pizza). Food choices shifted with 19% of diners opting for a healthy lunch bag and 29% of diners selecting a pizza dinner, moving away from the existing buffet. Examination of selections by those continuing to select from the concurrent buffet selections established that the availability of healthy alternatives in the buffet partially explained food choices, moderating any observed changes in food selections. The food service sector is a promising avenue through which dietary behaviours can be improved. Further studies, particularly those that measure selections over the longer term, and that include measures of satisfaction and profit, are needed.

Social-ecological influences on unhealthy dietary behaviours among Moroccan adolescents: a mixed-methods study

OBJECTIVE

To identify the prevalence of unhealthy dietary behaviours and their social-ecological influences in adolescents.

DESIGN

The study used a sequential explanatory mixed-methods design, which begins with the collection of quantitative data, followed by the collection of qualitative data to explain and enrich the quantitative findings. Quantitative data were collected via a global school-based student health survey and were analysed using quantitative approaches. Qualitative data were obtained via focus group discussions and were analysed thematically.

SETTING

Middle and high secondary schools in Taza city, Morocco.

PARTICIPANTS

Our quantitative analyses included 764 students (14-19 years). For the qualitative part, seventeen focus group discussions were conducted with 100 participants (fifty-six adolescents, twenty-six parents and eighteen teachers).

RESULTS

Of total student participants, 46·1 % skipped breakfast, 60·6 % had inadequate intake of fruits and vegetables (F&V), 39·4 % consumed soft drinks and 28·0 % consumed fast foods. All of these dietary behaviours could coexist in the same person except for inadequate intake of F&V. Gender, academic performance, age, perceived family income and education level of mother were associated with unhealthy dietary behaviours. Qualitative findings identified seven themes regarding social-ecological influences on adolescents' dietary behaviours: cognitive, affective/biological, lifestyle, outcome expectation, social network, accessibility/availability and macro-level influences.

CONCLUSIONS

The prevalence of unhealthy dietary behaviours in our study group is a concern. Dietary behaviours are the result of inseparable interactions among social-ecological influences. Modifiable factors identified may be useful when designing a future intervention aimed at improving breakfast and F&V consumption and reducing fast/snack-food consumption among adolescents.

Equity, Health, and Sustainability with PROVE: The Evaluation of a Portuguese Program for a Short Distance Supply Chain of Fruits and Vegetables

PROVE is a Portuguese program that empowers small-scale farmers organized into local networks to directly commercialize baskets of locally produced fruits and vegetables to consumers. This study applied a post-test-only non-equivalent group design to evaluate the resulting influence on the social empowerment of farmers and on consumer diets. The method included conducting a survey of PROVE farmers (n = 36) and a survey of PROVE consumers (n = 294) that were compared against matched samples of Portuguese respondents of international surveys (European Social Survey, n = 36 and the INHERIT Five-Country Survey, n = 571, respectively). PROVE farmers reported higher scores for perceived influence on the work environment than the national sample. PROVE consumers were more likely to eat five or more portions of fruits and vegetables a day in comparison to the matched sample of Portuguese citizens (average odds ratio: 3.05, p < 0.05). Being a PROVE consumer also generated an impact on the likelihood of consuming no more than two portions of red meat a week (average odds ratio: 1.56, p < 0.05). The evaluation study suggests that the promotion of short supply chains of fruits and vegetables can make a positive contribution to a healthier, more sustainable, and fairer future in food consumption.

Red meat and processed red meat consumption behaviour of healthcare professionals: do they participate in the World Health Organization's view of red meat carcasses and red meat carcinogens?

OBJECTIVE

This study investigated the consumption behaviours of healthcare professionals in relation to red meat and processed red meat products.

DESIGN

This study included a questionnaire conducted through face-to-face interviews with 149 health professionals. The purpose of the questionnaire was to determine the extent to which health professionals agreed with the WHO classification of red meat and processed red meat on their list of carcinogenic products.

SETTING

This research was carried out in İzmir, which is Turkey's third largest city. The survey was conducted in 2016 by holding face to face interviews with forty-three specialist doctors, sixteen doctors, twelve dentists, sixty-four nurses and fourteen pharmacists.

SUBJECTS

Nationally representative sample of healthcare professionals in Turkey.

RESULTS

People educated in healthcare are especially cautious about the consumption of processed red meat products. The results of the research revealed the importance of processing and cooking patterns in red meat consumption preferences.

CONCLUSIONS

The consequences of the research, in terms of breaking down prejudices and overcoming the anxieties of those with health concerns who do not consume red meat, are important. In fact, the results show that healthcare professionals consume red meat, but they are more careful in their consumption of processed red meat products. This result is in line with the WHO report.

Pattern and correlates of public support for public health interventions to reduce the consumption of sugar-sweetened beverages

OBJECTIVE

To examine the pattern and correlates of public support for twelve public health interventions aimed at reducing sugar-sweetened beverage (SSB) consumption.

DESIGN

Cross-sectional population-based survey. Respondents were recruited using a random digit dialling procedure (landline telephone) and a random selection of telephone numbers (mobile telephone). Sampling quotas were applied for age, and the sample was stratified according to administrative regions.

SETTING

The province of Québec, Canada.

SUBJECTS

One thousand adults aged between 18 and 64 years and able to answer the survey questionnaire in French or English.

RESULTS

Support was observed for a number of public health interventions, but the more intrusive approaches were less supported. Support for taxation as well as for sale and access restriction was positively associated with the perceived relevance of the government intervention, perceived effectiveness, and perceived associations between SSB consumption and chronic diseases. Believing that SSB consumption is a personal choice and daily consumption were generally negatively associated with strong support and positively associated with strong opposition. Sparse associations between sociodemographic and socio-economic characteristics were observed, with the exception of sex and age: women were generally more likely to support the examined public health strategies, while younger respondents were less likely to express support.

CONCLUSIONS

Increasing perceived effectiveness and government responsibility for addressing the issue of SSB consumption could lead to increased support for SSB interventions. Increasing the belief that SSB consumption could be associated with chronic diseases would increase support, but SSB consumers and younger individuals are expected to be resistant.

Development and Testing of the Healthy Food Pantry Assessment Tool

OBJECTIVE

To develop and test an observational survey that quantifies food pantry environments (FPE).

DESIGN

Best practices in FPE were identified through key informant interviews. The tool was pilot-tested, including a content review, and then field-tested for reliability.

SETTING

Key informant phone interviews (n = 41); pilot and field test visits occurred at 45 pantries from multiple states.

SUBJECTS

Food bank/pantry staff and nutrition educators were recruited for interviews through purposive and snowball sampling. Pilot and field test survey users (n = 65) were food pantry representatives and matched community partners who both rated the FPE using the tool.

VARIABLES MEASURED

Pearson correlation was used to determine test-retest and interrater reliability.

ANALYSIS

Qualitative data were coded for healthy FPE strategies. Quantitative data were calculated using descriptive statistics (significant at P < .05).

RESULTS

Qualitative data were coded for observable FPE characteristics. Reliability scores were substantial to nearly perfect for 48 of 61 survey items (79%) for test-retest and 49 of 61 (80%) for interrater reliability (Pearson r = .6-1.0).

CONCLUSIONS AND IMPLICATIONS

The Healthy Food Pantry Assessment Tool is research-tested and can be used to evaluate and quantify the healthfulness of FPE.

Changing the housing environment to reduce obesity in public housing residents: a cluster randomized trial

BACKGROUND

Public housing residents face significant social, economic, and physical barriers to the practice of health behaviors for prevention of chronic disease. Research shows that public housing residents are more likely to report higher rates of obesity, current smoking, disability, and insufficient physical activity compared to individuals not living in public housing. Because these behaviors and conditions may be shaped by the built and social environments in which they live, we conducted a study to test an environmental level diet and physical activity intervention targeting obesity among urban public housing developments.

METHODS

This study was a cluster randomized controlled trial of public housing developments, the unit of analysis and randomization. A total of 10 public housing developments were recruited and subsequently randomized to either receive the intervention package or to serve as comparison sites. The year-long intervention included components to change the dietary and physical activity-related environments of the developments. Surveys at baseline and one-year follow-up provided data on changes in behaviors and weight from participants in both intervention and control developments.

RESULTS

Intervention participants significantly changed their eating and activity behaviors and body weight from baseline to one-year follow-up (p's < .05) while comparison participants reported no significant changes in any study variable.

CONCLUSIONS

These data provide initial support for the idea that interventions targeting the environment of public housing developments can assist residents to change unhealthy behaviors and can possibly reduce the high levels of chronic disease among public housing residents.

Geographic Accessibility Of Food Outlets Not Associated With Body Mass Index Change Among Veterans, 2009-14

In recent years, various levels of government in the United States have adopted or discussed subsidies, tax breaks, zoning laws, and other public policies that promote geographic access to healthy food. However, there is little evidence from large-scale longitudinal or quasi-experimental research to suggest that the local mix of food outlets actually affects body mass index (BMI). We used a longitudinal design to examine whether the proximity of food outlets, by type, was associated with BMI changes between 2009 and 2014 among 1.7 million veterans in 382 metropolitan areas. We found no evidence that either absolute or relative geographic accessibility of supermarkets, fast-food restaurants, or mass merchandisers was associated with changes in an individual's BMI over time. While policies that alter only geographic access to food outlets may promote equitable access to healthy food and improve nutrition, our findings suggest they will do little to combat obesity in adults.

Enablers and barriers to improving worksite canteen nutrition in Pudong, China: a mixed-methods formative research study

OBJECTIVE

To identify individual-level and organisation-level enablers and barriers to the provision and consumption of healthier foods at worksite canteens in China and to develop a theoretical framework and evidence-based, specific, practical intervention strategies.

DESIGN

Mixed-methods formative research, with in-depth interviews, focus group discussions and quantitative questionnaires.

SETTING

Two community health centres (CHCs) in Pudong, Shanghai, China.

PARTICIPANTS

In-depth interviews with three CHC administrators and three canteen managers and staff. Six focus groups with a total of 19 male and 36 female employees, aged 25-67 years.

RESULTS

Three subthemes were identified as important for influencing individual food choice: the cultural perception of 'eating well', the need to balance taste preferences and nutrition, and the emphasis on food safety in healthfulness. At the organisation level, two related subthemes emerged: the balance of canteen budget and food safety with the variety and quality of offerings, and the interplay between key stakeholders. Key barriers included cost, poor communication between employees and management, individuals' emphasis on taste over healthfulness, variation in individual preferences and discordance between perceived and actual weight status, particularly among men. Key enablers included strong, positive food culture in China and trust in canteen food. An ecological framework to describe determinants of worksite food environment in Shanghai was developed and intervention strategies were mapped onto this framework.

CONCLUSIONS

A balancing act occurs at multiple levels and ultimately determines the worksite food environment and employee food choice at CHCs in Shanghai of China. There is a need to implement these findings and evaluate their impact on diet and health.

Social Environmental Correlates of Health Behaviors in a Faith-Based Policy and Environmental Change Intervention

Diet and physical activity are behavioral risk factors for many chronic diseases, which are among the most common health conditions in the United States. Yet most Americans fall short of meeting established dietary and physical activity guidelines. Faith-based organizations as settings for health promotion interventions can affect members at multiple levels of the social ecological model. The present study investigated whether change in the church social environment was associated with healthier behavior at church and in general at 1-year follow-up. Six churches received mini-grants and technical assistance for 1 year to support policy and environmental changes for healthy eating (HE) and physical activity (PA). Socioenvironmental (social support and social norms) and behavioral (HE and PA at church and in general) outcomes were derived from baseline and 1-year follow-up church member surveys ( n = 258). Three of six churches demonstrated significant improvements in all three socioenvironmental aspects of HE. Two of five churches exhibited significant socioenvironmental improvements for PA at follow-up. Church social environmental changes were related to health behaviors at church and in general ( p < .05). Change in social support for HE, social support for PA, and social norms for PA were each associated with three church-based and general behavioral outcomes. Social norms for healthy eating were related to two general behavior outcomes and social norms for unhealthy eating to one general behavioral outcome. Study findings demonstrate that socioenvironmental characteristics are essential to multilevel interventions and merit consideration in designing policy and environmental change interventions.

Weight and Veterans' Environments Study (WAVES) I and II: Rationale, Methods, and Cohort Characteristics

PURPOSE

To present the rationale, methods, and cohort characteristics for 2 complementary "big data" studies of residential environment contributions to body weight, metabolic risk, and weight management program participation and effectiveness.

DESIGN

Retrospective cohort.

SETTING

Continental United States.

PARTICIPANTS

A total of 3 261 115 veterans who received Department of Veterans Affairs (VA) health care in 2009 to 2014, including 169 910 weight management program participants and a propensity score-derived comparison group.

INTERVENTION

The VA MOVE! weight management program, an evidence-based lifestyle intervention.

MEASURES

Body mass index, metabolic risk measures, and MOVE! participation; residential environmental attributes (eg, food outlet availability and walkability); and MOVE! program characteristics.

ANALYSIS

Descriptive statistics presented on cohort characteristics and environments where they live.

RESULTS

Forty-four percent of men and 42.8% of women were obese, whereas 4.9% of men and 9.9% of women engaged in MOVE!. About half of the cohort had at least 1 supermarket within 1 mile of their home, whereas they averaged close to 4 convenience stores (3.6 for men, 3.9 for women) and 8 fast-food restaurants (7.9 for men, 8.2 for women). Forty-one percent of men and 38.6% of women did not have a park, and 35.5% of men and 31.3% of women did not have a commercial fitness facility within 1 mile.

CONCLUSION

Drawing on a large nationwide cohort residing in diverse environments, these studies are poised to significantly inform policy and weight management program design.

Are Perceived and Objective Distances to Fresh Food and Physical Activity Resources Associated with Cardiometabolic Risk?

Perceived and objective measures of neighbourhood features have shown limited correspondence. Few studies have examined whether discordance between objective measures and individual perceptions of neighbourhood environments relates to individual health. Individuals with mismatched perceptions may benefit from initiatives to improve understandings of resource availability. This study utilised data from n = 1491 adult participants in a biomedical cohort to evaluate cross-sectional associations between measures of access (perceived, objective, and perceived-objective mismatch) to fruit and vegetable retailers (FVR) and public open space (POS), and clinically-measured metabolic syndrome and its component risk factors: central obesity, dyslipidaemia, hypertension and pre-diabetes/diabetes. Access measures included perceived distances from home to the nearest FVR and POS, corresponding objectively-assessed road network distances, and the discordance between perceived and objective distances (overestimated (i.e., mismatched) distances versus matched perceived-objective distances). Individual and neighbourhood measures were spatially joined using a geographic information system. Associations were evaluated using multilevel logistic regression, accounting for individual and area-level covariates. Hypertension was positively associated with perceived distances to FVR (odds ratio (OR) = 1.14, 95% confidence interval (CI) = 1.02, 1.28) and POS (OR = 1.19, 95% CI = 1.05, 1.34), after accounting for covariates and objective distances. Hypertension was positively associated with overestimating distances to FVR (OR = 1.36, 95% CI = 1.02, 1.80). Overestimating distances to POS was positively associated with both hypertension (OR = 1.42, 95% CI = 1.11, 1.83) and dyslipidaemia (OR = 1.25, 95% CI = 1.00, 1.57). Results provide new evidence for specific associations between perceived and overestimated distances from home to nearby resources and cardiometabolic risk factors.

Embedding weight management into safety-net pediatric primary care: randomized controlled trial

Background

Implementing evidence-based recommendations for treating pediatric overweight and obesity is challenging in low-resource settings. We conducted a randomized controlled trial to evaluate the effects of implementing the American Academy of Pediatrics overweight/obesity recommendations using a Standard Care approach alone or with the addition of an enhanced program in a safety-net pediatric primary care setting (located in Bronx, New York, United States).

Methods

In a 12-month trial, families of children (age 7–12 years; body mass index ≥85th American percentile for age and sex; 74% self-identified as Hispanic/Latino; n = 360) were randomly assigned to receive Standard Care Alone or Standard Care + Enhanced Program. An English/Spanish bilingual staff provided the Standard Care Alone consisting of quarterly semi-structured pediatrician visits targeting family-based behavioral changes. The Standard Care + Enhanced Program was enriched with eight Skill-Building Core and monthly Post-Core Support sessions.

Results

The mean body mass index Z-score declined in both arms (P < 0.01) with no significant difference between the Standard Care Alone (0.12 kg [SE: 0.03]) and Standard Care + Enhanced Program (0.15 kg [SE: 0.03]) arm (P = 0.15). Compared to the Standard Care Alone, the Standard Care + Enhanced Program resulted in significantly greater improvements in total cholesterol (P = 0.05), low-density lipoprotein cholesterol (P = 0.04), aspartate aminotransferase (P = 0.02), and alanine transaminase (P = 0.03) concentrations.

Conclusions

Safety-net primary care settings can provide efficacious pediatric weight management services. Targeted family-based behavioral counseling helps overweight/obese children achieve a modest body mass index Z-score improvement. A more intensive lifestyle intervention program may improve some metabolic parameters.

The Development and Public Health Implications of Food Preferences in Children

Food preferences are a primary determinant of dietary intake and behaviors, and they persist from early childhood into later life. As such, establishing preferences for healthy foods from a young age is a promising approach to improving diet quality, a leading contributor to cardiometabolic health. This narrative review first describes the critical period for food preference development starting in utero and continuing through early childhood. Infants’ innate aversion to sour and bitter tastes can lead them to initially reject some healthy foods such as vegetables. Infants can learn to like these foods through exposures to their flavors in utero and through breastmilk. As solid foods are introduced through toddlerhood, children’s food preferences are shaped by parent feeding practices and environmental factors such as food advertising. Next, we discuss two key focus areas to improve diet quality highlighted by the current understanding of food preferences: (1) promoting healthy food preferences through breastfeeding and early exposures to healthy foods and (2) limiting the extent to which innate preferences for sweet and salty tastes lead to poor diet quality. We use an ecological framework to summarize potential points of intervention and provide recommendations for these focus areas, such as worksite benefits that promote breastfeeding, and changes in food retail and service environments. Individuals’ choices around breastfeeding and diet may ultimately be influenced by policy and community-level factors. It is thus crucial to take a multilevel approach to establish healthy food preferences from a young age, which have the potential to translate into lifelong healthy diet.

A Cluster Randomized Trial to Promote Healthy Menu Items for Children: The Kids' Choice Restaurant Program

Evidence indicates that restaurant-based interventions have the potential to promote healthier purchasing and improve the nutrients consumed. This study adds to this body of research by reporting the results of a trial focused on promoting the sale of healthy child menu items in independently owned restaurants. Eight pair-matched restaurants that met the eligibility criteria were randomized to a menu-only versus a menu-plus intervention condition. Both of the conditions implemented new healthy child menu items and received support for implementation for eight weeks. The menu-plus condition also conducted a marketing campaign involving employee trainings and promotional materials. Process evaluation data captured intervention implementation. Sales of new and existing child menu items were tracked for 16 weeks. Results indicated that the interventions were implemented with moderate to high fidelity depending on the component. Sales of new healthy child menu items occurred immediately, but decreased during the post-intervention period in both conditions. Sales of existing child menu items demonstrated a time by condition effect with restaurants in the menu-plus condition observing significant decreases and menu-only restaurants observing significant increases in sales of existing child menu items. Additional efforts are needed to inform sustainable methods for improving access to healthy foods and beverages in restaurants.

How Latina mothers navigate a 'food swamp' to feed their children: a photovoice approach

OBJECTIVE

To understand how mothers who recently migrated from Central America to the USA feed their children in a neighbourhood saturated with unhealthful food choices ('food swamp') and to formulate a mother-driven plan of action to facilitate their acquisition of foods. Design/Setting/Subjects We purposively sampled mothers with children (<10 years old) who were recent immigrants/refugees from Central America and lived in a 'food swamp' neighbourhood. We used the photovoice approach to elicit textual data from thirty in-depth interviews, a participatory workshop, and visual data from photographs. Analyses were guided by the Social Ecological Framework and Social Cognitive Theory to identify barriers, facilitators and strategies that support parents in feeding their children.

RESULTS

Mothers valued foods that they considered to be 'traditional' and 'healthful'. They navigated their food retail environment looking for these foods (of good quality and well-priced). Food values were reinforced by pre-migration food customs and culture, health professionals' advice and, in some cases, by the desire to avoid conflict with their children. The neighbourhood food environment could directly influence children's food preferences and often created conflict between what the child wanted to eat and the foods that mothers valued. Mothers in this 'food swamp' wanted to be engaged in addressing the selection of foods offered in schools and in neighbourhood food venues to reflect their own food values.

CONCLUSIONS

These mothers' feeding choices were influenced directly by their food values, and indirectly by the neighbourhood and school food environments via their children's preferences.

Five Community-wide Approaches to Physical Activity Promotion: A Cluster Analysis of These Activities in Local Health Jurisdictions in 6 States

OBJECTIVE

Local health departments (LHDs) have essential roles to play in ensuring the promotion of physical activity (PA) in their communities in order to reduce obesity. Little research exists, however, regarding the existence of these PA interventions across communities and how these interventions may impact community health.

DESIGN

In this exploratory study, we used cluster analysis to identify the structure of co-occurring PA interventions, followed by regression analysis to quantify the association between the patterns of PA interventions and prevalence of PA and obesity at a population level.

SETTING

Our study setting included local health jurisdictions in Colorado, Florida, Minnesota, New Jersey, Tennessee, and Washington.

PARTICIPANTS

Participating jurisdictions were those 218 local health jurisdictions (mostly counties) from which LHD leaders had provided data in 2013 for the Multi-Network Practice and Outcome Variation Examination Study.

MAIN OUTCOME MEASURES

We obtained unique public health activities data on PA interventions conducted in 2012 from 218 LHDs in 6 participating states. We categorized jurisdictions using cluster analysis, based on PA intervention approaches indicated by LHD leaders as available in their communities and then examined associations between categories and prevalence of obesity and of residents engaged in PA.

RESULTS

We identified 5 distinct PA intervention categories representing community-wide approaches-Comprehensive Approach, Built Environment, Personal Health, School-Based Interventions, and No Apparent Activities. Prevalence rates of obesity and PA among jurisdictions in the intervention clusters were significantly different from jurisdictions with No Apparent Activities, with more population-level approaches most significantly related to beneficial outcomes.

CONCLUSION

Our findings suggest the importance of standardized public health services data for generating evidence regarding health-related outcomes. The intervention categories we identified appear to reflect broad, local community-wide prevention approaches and demonstrated that population-level PA interventions can be testable and may have particularly beneficial relationships to community health. Widespread adoption of such standardized data depicting local public health prevention activity could support monitoring practice change, performance improvement, comparisons across communities that could reduce unnecessary variation, and the generation of evidence for public health practice and policy-making.

The impact of interventions to promote healthier ready-to-eat meals (to eat in, to take away or to be delivered) sold by specific food outlets open to the general public: a systematic review

INTRODUCTION

Ready-to-eat meals sold by food outlets that are accessible to the general public are an important target for public health intervention. We conducted a systematic review to assess the impact of such interventions.

METHODS

Studies of any design and duration that included any consumer-level or food-outlet-level before-and-after data were included.

RESULTS

Thirty studies describing 34 interventions were categorized by type and coded against the Nuffield intervention ladder: restrict choice = trans fat law (n = 1), changing pre-packed children's meal content (n = 1) and food outlet award schemes (n = 2); guide choice = price increases for unhealthier choices (n = 1), incentive (contingent reward) (n = 1) and price decreases for healthier choices (n = 2); enable choice = signposting (highlighting healthier/unhealthier options) (n = 10) and telemarketing (offering support for the provision of healthier options to businesses via telephone) (n = 2); and provide information = calorie labelling law (n = 12), voluntary nutrient labelling (n = 1) and personalized receipts (n = 1). Most interventions were aimed at adults in US fast food chains and assessed customer-level outcomes. More 'intrusive' interventions that restricted or guided choice generally showed a positive impact on food-outlet-level and customer-level outcomes. However, interventions that simply provided information or enabled choice had a negligible impact.

CONCLUSION

Interventions to promote healthier ready-to-eat meals sold by food outlets should restrict choice or guide choice through incentives/disincentives. Public health policies and practice that simply involve providing information are unlikely to be effective.

OPREVENT2: Design of a multi-institutional intervention for obesity control and prevention for American Indian adults

Background

Obesity and other nutrition-related chronic disease rates are high in American Indian (AI) populations, and an urgent need exists to identify evidence-based strategies for prevention and treatment. Multi-level, multi-component (MLMC) interventions are needed, but there are significant knowledge gaps on how to deliver these types of interventions in low-income rural AI communities.

Methods

OPREVENT2 is a MLMC intervention targeting AI adults living in six rural reservations in New Mexico and Wisconsin. Aiming to prevent and reduce obesity in adults by working at multiple levels of the food and physical activity (PA) environments, OPREVENT2 focuses on evidence-based strategies known to increase access to, demand for, and consumption of healthier foods and beverages, and increase worksite and home-based opportunities for PA. OPREVENT2 works to create systems-level change by partnering with tribal stakeholders, multiple levels of the food and PA environment (food stores, worksites, schools), and the social environment (children as change agents, families, social media). Extensive evaluation will be conducted at each level of the intervention to assess effectiveness via process and impact measures.

Discussion

Novel aspects of OPREVENT2 include: active engagement with stakeholders at many levels (policy, institutional, and at multiple levels of the food and PA system); use of community-based strategies to engage policymakers and other key stakeholders (community workshops, action committees); emphasis on both the built environment (intervening with retail food sources) and the social environment. This paper describes the design of the intervention and the evaluation plan of the OPREVENT2.

Neighborhood Disparities in the Restaurant Food Environment

IMPORTANCE

Restaurant meals account for a significant portion of the American diet. Investigating disparities in the restaurant food environment can inform targeted interventions to increase opportunities for healthy eating among those who need them most.

OBJECTIVE

To examine neighborhood disparities in restaurant density and the nutrition environment within restaurants among a statewide sample of Wisconsin households.

METHODS

Households (N = 259) were selected from the 2009-2010 Survey of the Health of Wisconsin (SHOW), a population-based survey of Wisconsin adults. Restaurants in the household neighborhood were enumerated and audited using the Nutrition Environment Measures Survey for Restaurants (NEMS-R). Neighborhoods were defined as a 2- and 5-mile street-distance buffer around households in urban and non-urban areas, respectively. Adjusted linear regression models identified independent associations between sociodemographic household characteristics and neighborhood restaurant density and nutrition environment scores.

RESULTS

On average, each neighborhood contained approximately 26 restaurants. On average, restaurants obtained 36.1% of the total nutrition environment points. After adjusting for household characteristics, higher restaurant density was associated with both younger and older household average age (P < .05), all white households (P = .01), and urban location (P < .001). Compared to rural neighborhoods, urban and suburban neighborhoods had slightly higher (ie, healthier) nutrition environment scores (P < .001).

CONCLUSIONS AND RELEVANCE

The restaurant food environment in Wisconsin neighborhoods varies by age, race, and urbanicity, but offers ample room for improvement across socioeconomic groups and urbanicity levels. Future research must identify policy and environmental interventions to promote healthy eating in all restaurants, especially in young and/or rural neighborhoods in Wisconsin.
