Differences in a Chain Supermarket's Sales to SNAP Shoppers Before and Since the COVID-19 Pandemic

OBJECTIVE

This study 1) compares grocery sales to Supplemental Nutrition Assistance Program (SNAP) shoppers in rural and urban grocery stores and 2) estimates changes in sales to SNAP shoppers in North Carolina (NC) since the pandemic.

DESIGN

Weekly transaction data among loyalty shoppers at a large grocery chain across NC from October 2019 to December 2020 (n = 32; 182 store weeks) to assess nutritional outcomes.

SETTING

North Carolina large chain grocery stores.

PARTICIPANTS

Large chain grocery store/SNAP shoppers.

INTERVENTION

Rural/urban status of the stores and COVID-19 pandemic onset.

MAIN OUTCOME MEASURES

Share of total calories sold from fruits, vegetables, nuts, and legumes (FVNL) with and without additives, sugar-sweetened beverages (SSB), less healthful foods (LHF), and processed meats (PM).

ANALYSIS

Multivariate random effects models with robust standard errors to examine the association of rural/urban status before and since coronavirus disease 2019 with the share of calories sold to SNAP shoppers from each food category. We controlled for county-level factors (eg, sociodemographic composition, food environment) and store-level factors.

RESULTS

We did not find significant rural-urban differences in the composition of sales to SNAP shoppers in adjusted models. There was a significant decrease in the mean share of total calories from sugar-sweetened beverages (-0.43%) and less healthful food (-1.32%) and an increase in the share from processed meats (0.09%) compared with before the pandemic (P < 0.05).

CONCLUSIONS AND IMPLICATIONS

Urban-rural definitions are insufficient to understand nuances in food environments, and more support is needed to ensure healthy food access.

Diet-Related Disparities and Childcare Food Environments for Vulnerable Children in South Korea: A Mixed-Methods Study

Diet-related disparities that have often been observed in vulnerable families may play a negative role in children's health and health-related quality of life. In South Korea, an afterschool care policy, called Community Childcare Center (CCC), was established in the 1960s to protect and educate vulnerable children; this role has expanded to provide meal services in recent times. Therefore, the CCCs' food environment has become a pivotal platform for observing children's nutrition and health-related disparities. Using a mixed-methods approach including a survey with self-reported questionnaires, field observation, and participant interviews, the food environment of CCC was explored alongside children's eating behaviors. Eating behaviors were not as healthy as expected. Although service providers and cooks reported in the survey responses that the centers' food environment was healthy, participant observations and interviews revealed a significant gap. Establishing a standardized food environment and improving the nutrition literacy of workers as a significant human resource at a CCC can promote healthy eating for vulnerable children. The findings suggest that in the absence of steps to improve the food environment of CCC, diet-related disparities may affect children's health in the future.

Factors affecting fruit and vegetable consumption and purchase behavior of adults in sub-Saharan Africa: A rapid review

In order to achieve the Sustainable Development Goals, considerable dietary shifts, including an increase in the consumption of fruit and vegetables (FV) will be required. However, worldwide consumption of FV is far below international recommendations, including in many low- and middle-income countries (LMICs), particularly in Africa. Understanding what, where, when, and how people choose to eat requires an understanding of how individuals are influenced by factors in their social, physical, and macro-level environments. In order to develop effective interventions to increase fruit and vegetable consumption, the factors influencing consumer behavior need to be better understood. We conducted a rapid review to assess and synthesize data on individual, social, physical, and macro-level factors that enable or constrain fruit and vegetable consumption and purchase among adults living in sub-Saharan Africa. Our conceptual framework is based on a socio-ecological model which has been adapted to settings in LMICs and Africa. We systematically searched four electronic databases including Scopus, Medline (PubMed), PsycInfo, and African Index Medicus, and screened Google Scholar for gray literature. We included a total of 52 studies and narratively summarized the existing evidence for each identified factor across the different levels. We found that most studies assessed demographic factors at the individual level including household or family income, socio-economic status and education. Furthermore we identified a variety of important factors that influence FV consumption, in the social, physical, and macro environment. These include women's empowerment and gender inequalities, the influence of neighborhood and retail food environment such as distance to market and price of FV as well as the importance of natural landscapes including forest areas for FV consumption. This review identified the need to develop and improve indicators both for exposure and outcome variables but also to diversify research approaches.

Food Insecurity, the Food Environment, and COVID-19 in Rural South Carolina

In this study, we explored the relationship between the food environment and food security among rural adults during the COVID-19 pandemic. Researchers, with assistance from community partners, conducted a cross-sectional survey assessing the impact of COVID-19 on food access, food security, and physical activity in 9 rural South Carolina (SC) counties. This survey was administered to a purposive sample (N = 587) from August 2020 to March 2021. The dependent variable was a binary indicator of food insecurity (past 3 months), in accordance with the USDA Household Food Security Survey Module. Independent variables were sociodemographic characteristics, food environment factors (eg, shopping at grocery stores, partial markets, and farmers' markets), and shopping behaviors during the pandemic. Overall, 31% of respondents were food insecure. Food security status differed by income and household composition. Results indicate that the odds of food insecurity were higher for respondents who shopped frequently at partial markets (adjusted odds ratio [AOR] = 1.61, 95% confidence interval [CI]: 1.01-2.56) and shopped more for food before the pandemic than during the pandemic (AOR = 1.68, 95% CI: 1.07-2.64). Findings underscore the importance of examining the relationship between the food environment and food insecurity during COVID-19 in rural settings.

Food environment around schools and adolescent consumption of unhealthy foods in Addis Ababa, Ethiopia

Adolescent diets may be influenced by the retail food environment around schools. However, international research to examine associations between the proximity of retail food outlets to schools and diet provides equivocal support for an association. This study aims to understand the school food environment and drivers for adolescents' consumption of unhealthy foods in Addis Ababa, Ethiopia. Mixed-methods research was conducted, 1200 adolescents (10-14 years) from randomly selected government schools were surveyed, along with vendors within 5-min' walk of the schools and focus group discussions (FGDs) with adolescent groups. Mixed-effect logistic regression investigated the relationship between the number of vendors around the schools and the consumption of selected unhealthy foods. Thematic analysis was used to summarize findings from the FGDs. Consumption of sweets and sugar-sweetened beverages (S-SSB) and deep-fried foods (DFF) at least once a week was reported by 78.6% and 54.3% of the adolescents, respectively. Although all schools were surrounded by food vendors selling DFF and S-SSB, consumption was not associated with the number of vendors available around the school. However, adolescents' awareness and perception of healthy food, and their concerns about the safety of foods in the market, influenced their dietary choices and behaviours. Lack of financial resources to purchase food as desired also played a role in their selection of food and eating habits. Reported unhealthy food consumption is high among adolescents in Addis Ababa. Thus, further research is warranted to come up with school-based interventions that promote access and healthy food choices among adolescents.

Healthier diets for all? A systematic review and meta-analysis examining socioeconomic equity of the effect of increasing availability of healthier foods on food choice and energy intake

Widespread availability of unhealthy food and drink products may contribute to socioeconomic patterning in obesity. Therefore, increasing the availability of healthier foods may be one approach to reducing obesity without widening existing inequalities. This systematic review and meta-analysis examined the impact of increasing the availability of healthier food and drink on consumer behavior among individuals with higher and lower socioeconomic position (SEP). Eligible studies were required to use experimental designs to compare conditions of higher vs lower availability of healthier vs less healthy options on food choice-related outcomes and measure SEP. Thirteen eligible studies were included. Odds of choosing a healthy item were higher when availability was increased for higher (OR = 5.0, 95% CI: 3.3, 7.7) and lower (OR = 4.9, CI: 3.0, 8.0) SEP. Increased availability of healthier foods was also associated with a decrease in energy content of selections for higher (-131 kcal; CI: -76, -187) and lower (-109 kcal; CI: -73, -147) SEP. There was no SEP moderation. Increasing the relative availability of healthier foods may be an equitable and effective approach to improve population-level diet and address obesity, though more research is required testing this in real-world environments.

Diet Quality of Older African Americans: Impact of Knowledge and Perceived Threat of COVID-19

Confusing health messages and environmental changes intended to prevent the spread of the COVID-19 virus have affected the dietary behavior of older African Americans. We investigated the impact of COVID-19-related factors on diet quality and the relationship between food access and diet quality. We surveyed 150 African Americans aged 55 years and above during the COVID-19 pandemic. The data obtained included socio-demographic and health information, and COVID-19-related knowledge and perceptions. Dietary intake data was obtained using the Diet History Questionnaire III. Analyses included bivariate and multivariable statistics. Overall, based on United States Department of Agriculture guidelines, the diet quality of older African Americans was poor. Lower knowledge and a lower perceived threat of COVID-19 were significantly associated with poor diet quality. Additionally, older African Americans with chronic diseases and food insecurity had poor diet quality. The COVID-19 pandemic has highlighted the fragility of diet quality. The combined impact of poor knowledge and perceived threat of COVID-19, chronic disease, and food insecurity contribute to poor diet quality in this population. This study adds to the well-known need for strategies to support the right to a healthy diet, particularly during COVID-19 and future pandemics. Proactive interventions to counteract the potential consequences of poor diets are needed.

Examining differences in children and adolescents' exposure to food and beverage marketing in Canada by sociodemographic characteristics: Findings from the International Food Policy Study Youth Survey, 2020

BACKGROUND

Many countries, including Canada, are considering regulations to restrict food and beverage marketing to children. However, little evidence is available outside of the US on how marketing exposure differs across sociodemographic subgroups.

OBJECTIVE

To investigate potential associations between child and adolescent sociodemographic characteristics and exposure to food and beverage marketing in Canada.

METHODS

Participants (n = 3780) aged 10-17 self-reported exposure to food and beverage marketing across food categories, locations and marketing techniques. Logistic regression models tested relationships between sociodemographics (age, sex, ethnicity and income adequacy) and marketing exposure.

RESULTS

Among other differences identified, 13-17 years old were more likely than 10-12 years old to report seeing unhealthy food marketing online. Girls were more likely than boys to see such marketing online and in retail settings, while boys were more likely to see it in video games. Minority ethnicities (including Indigenous youth) and respondents with lower income adequacy generally reported more exposure than White and higher income respondents, respectively.

CONCLUSIONS

This study highlights important differences in marketing exposure among youth of different sociodemographic groups in Canada, including greater exposure to marketing among those most disadvantaged and emphasizes the essential need to consider food marketing across equity groups when developing restrictions on marketing to kids.

Marketing Sustainability Analysis of Stores Participating in a Healthier Retail Food Program

OBJECTIVES

To examine how food retailers completing Shop Healthy NYC, a healthy food retail program, (1) changed availability, placement, and promotion of healthier food immediately after participation and (2) sustained changes 1-year postintervention.

METHODS

From 2014 to 2017, stores in 2 high-poverty New York City neighborhoods participated in a low-intensity intervention focused on in-store advertising or a high-intensity intervention to meet 7 criteria related to availability, placement, and promotion of healthy items. Stores were assessed preintervention (Pre), 1-month postintervention (Post 1), and 12-16 months postintervention (Post 2). Analyses were restricted to stores that completed the intervention and were assessed at all time points (n = 64). Changes were compared across time points.

RESULTS

Across stores participating in the low-intensity intervention, the ratio of unhealthy-to-healthy ads decreased from Pre to Post 1, and by Post 2 remained improved over baseline. Among stores participating in the high-intensity intervention, the median number of healthy criteria met increased from 3.5 to 6 from Pre to Post 1 and decreased to 5 at Post 2.

CONCLUSIONS

Improvements in the marketing and availability, placement, and promotion of healthy products are feasible but may require reinforcement and additional support over time.

Association of fast-food restaurants with overweight and obesity in school-aged children and adolescents: A systematic review and meta-analysis

We aimed to explore associations between the accessibility of fast-food restaurants (FFRs) and weight-related outcomes in children and adolescents through a systematic review and meta-analysis of studies. We searched three databases for studies published before October 21, 2022. Study quality was assessed using the National Institutes of Health's Quality Assessment Tool for Observational Cohort and Cross-Sectional Studies. Meta-analysis was performed, and the leave-one-out method was used for sensitivity analysis. A total of 60 studies were included. According to our analysis, FFRs within a smaller buffer radius from residences or that provide unhealthy foods may have a more significant influence on children's and adolescents' weight. Children of younger ages and girls may have a higher possibility of being overweight due to FFRs. Though we could hardly avoid bias, the estimates in low-and middle-income countries (only six studies) are much higher than those in high-income countries (54 studies). More research analyses based on microscope data and individual economic levels are needed. This study yields quantitative results, provides policymakers and urban planners with a theoretical support for building resilient and sustainable human settlements, and promotes the translation of research findings from public health to environmental planning.

Public Support for Nutrition-Related Actions by Food Companies in Australia: A Cross-Sectional Analysis of Findings from the 2020 International Food Policy Study

Unhealthy food environments contribute to unhealthy population diets. In Australia, the government currently relies on voluntary food company actions (e.g., related to front-of-pack labelling, restricting promotion of unhealthy foods, and product formulation) as part of their efforts to improve population diets, despite evidence that such voluntary approaches are less effective than mandatory policies. This study aimed to understand public perceptions of potential food industry nutrition-related actions in Australia. An online survey was completed by 4289 Australians in 2020 as part of the International Food Policy Study. The level of public support was assessed for six different nutrition-related actions related to food labelling, food promotion, and product formulation. High levels of support were observed for all six company actions, with the highest support observed for displaying the Health Star Rating on all products (80.4%) and restricting children's exposure to online promotion of unhealthy food (76.8%). Findings suggest the Australian public is strongly supportive of food companies taking action to improve nutrition and the healthiness of food environments. However, given the limitations of the voluntary action from food companies, mandatory policy action by the Australian government is likely to be needed to ensure company practices align with public expectations.

Development of the Menu Assessment Scoring Tool (MAST) to Assess the Nutritional Quality of Food Service Menus

Preventing the rise in obesity is a global public health priority. Neighbourhood environments can help or undermine people's efforts to manage their weight, depending on availability of nutritious and nutrient-poor 'discretionary' foods. The proportion of household food budgets spent on eating outside the home is increasing. To inform nutrition policy at a local level, an objective assessment of the nutritional quality of foods and beverages on food service menus that is context-specific is needed. This study describes the development and piloting of the Menu Assessment Scoring Tool (MAST), used to assess the nutritional quality of food service menus in Australia. The MAST is a desk-based tool designed to objectively assess availability of nutrient-poor and absence of nutritious food and beverages on food service menus. A risk assessment approach was applied, using the best available evidence in an iterative way. MAST scores for 30 food service outlets in one Local Government Authority in Perth, Western Australia highlight opportunities for improvements. MAST is the first tool of its kind in Australia to assess the nutritional quality of food service menus. It was practical and feasible to use by public health nutritionists/dietitians and can be adapted to suit other settings or countries.

Can Ordering Groceries Online Support Diet Quality in Adults Who Live in Low Food Access and Low-Income Environments?

During the COVID-19 pandemic, U.S. food assistance programs allowed the use of program benefits to order groceries online. We examined relationships between the food environment, food assistance, online grocery ordering, and diet quality among adults from one low-income, low food access community in Northeastern Connecticut during the pandemic. Via online survey, adults (n = 276) reported their perceived home and store food environments, food assistance participation, whether they ordered groceries online, and consumption frequency and liking of foods/beverages to calculate diet quality indices. Those who ordered groceries online (44.6%) were more likely to participate in food assistance programs and report greater diet quality. Perceived healthiness of store and home food environments was variable, with the ease of obtaining and selecting unhealthy foods in the neighborhood significantly greater than healthy foods. Healthier perceived home food environments were associated with significantly higher diet qualities, especially among individuals who participated in multiple food assistance programs. Ordering groceries online interacted with multiple measures of the food environment to influence diet quality. Generally, the poorest diet quality was observed among individuals who perceived their store and home food environments as least healthy and who did not order groceries online. Thus, ordering groceries online may support higher diet quality among adults who can use their food assistance for purchasing groceries online and who live in low-income, low-access food environments.

Food and Physical Activity Environment in the US-Affiliated Pacific Region: The Children's Healthy Living Program

OBJECTIVE

To describe the quality of food and physical activity (PA) environments by World Bank Income level in jurisdictions from the Children's Healthy Living Program.

DESIGN

Baseline cross-sectional community data were analyzed from 11 jurisdictions categorized by World Bank Income levels to describe exposure to different food and PA outlets. The Children's Healthy Living Program was a multilevel, multijurisdictional prevalence study and community intervention trial that reduced child obesity in the US-Affiliated Pacific region.

SETTING

US-Affiliated Pacific region.

PARTICIPANTS

Food (n = 426) and PA (n = 552) Outlets.

MAIN OUTCOME MEASURES

Physical activity and food scores that reflect the quality of the outlets that support being physically active and healthy eating options, respectively.

ANALYSIS

Descriptive statistics are presented as means ± SD or percentages.

RESULTS

High-income-income level jurisdictions had higher food and PA scores than middle-income level jurisdictions.

CONCLUSIONS AND IMPLICATIONS

The US-Affiliated Pacific region has limited quality food and PA outlets in underserved communities at risk for obesity. The findings in this paper can be used to develop tools and design interventions to improve the food and PA environment to increase a healthier, active lifestyle.

A mixed-methods evaluation of a health-promoting café located in a small health service in rural Victoria, Australia

INTRODUCTION

Residents of rural areas internationally typically experience chronic disease risk profiles worse than city dwellers. Poor diet, a key driver of chronic disease, has been associated with unhealthy food environments, and rural areas often experience limited access to healthy, fresh and affordable food.

OBJECTIVE

This study aimed to evaluate the first three years of a health promoting social enterprise café established in a small rural health service.

DESIGN

A mixed-methods evaluation study. Quantitative sales data, surveys and key informant interviews that included both quantitative and qualitative responses.

FINDINGS

Three years of sales data were included; 111customer surveys and five key informant interviews were conducted. Food and beverages on displayed and sold consistently met or exceeded the healthy criteria set by policy. Stakeholders supported the traffic light system, the social enterprise model and rated the likelihood of sustainability of the café as high.

DISCUSSION

Customers used the 'traffic light' system to inform food choices, placed value on the warmth of the staff and on the welcoming environment created through the social enterprise model. Resources remain tight although all stakeholders are committed to the sustainability of the YarriYak café.

CONCLUSION

The study shows the acceptability, feasibility and sustainability of a health promoting social enterprise café in a rural area.

[Relationship between the dietary behavior targets of Health Japan 21 (second term) and perceived food environment and health literacy]

Objective　The interim evaluation of Health Japan 21(second term), a national health promotion plan, suggested that improvements in the food environment did not lead to improvements in individual dietary habits. The present study aimed to evaluate the relationship between the dietary behavior targets of Health Japan 21 (second term) and perceived food environment and health literacy.Method　We conducted an online cross-sectional survey in March 2019 among adults aged 20-64 years. From the 9,667 registered monitors of the research firm, we collected 2,851 responses (29.5% response rate). The perceived food environment (how people perceive the local food environment) was estimated using the following six questions, namely, availability: easy access to nutritionally balanced meals, accessibility: no inconvenience in daily shopping, affordability: access to nutritionally balanced meals at reasonable prices, accommodation: easy access to food services within business hours, acceptability: satisfaction with the quality of food ingredients, and another form of acceptability: adequate food safety. Health literacy was evaluated using five questions related to information gathering, information selection, information transfer, information judgment, and self-determination. Last, we asked the respondents about two dietary behaviors, namely, the frequency of a balanced diet (defined as comprising the staple food, a main dish, and a side dish) and the quantity of vegetable intake, along with sociodemographic information. The analysis included 2,111 respondents, excluding those whose socioeconomic status was unknown. Multiple logistic regression analyses were performed to determine the relationship between perceived food environment and health literacy on dietary behaviors, while adjusting for sociodemographic factors.Result　A balanced diet was associated with the following perceptions of the food environment: "access to nutritionally balanced meals at reasonable prices" (adjusted odds ratio [95% confidence interval] = 1.37 [1.02, 1.82]; women), and "adequate food safety" (1.54 [1.19, 1.98]; men), and health literacy: "information gathering" (0.84 [0.73,0.97]; men) and "self-determination" (1.28 [1.10,1.50], 1.37 [1.14,1.63]; men, women). The quantity of vegetable intake was associated with the following perceptions of the food environment: "easy access to nutritionally balanced meals" (1.54 [1.15,2.06]; men), and "no inconvenience in daily shopping" (1.55 [1.12,2.15]; women), and health literacy: "information transfer" (1.30 [1.10,1.54]; men), and "self-determination" (1.67 [1.38,2.02]; women)).Conclusion　To achieve a balanced diet and increased vegetable intake in a population, it is necessary to promote both the acquisition of a higher level of "self-determination" (rather than "information gathering") in health literacy and the creation of a heathy food environment.

The Association between the School Environment and Adolescent Alcohol Drinking Behavior in Six Cities in China

Drinking alcohol during adolescence has short-term and long-term effects on physical and mental health. At this stage, teenagers are greatly influenced by their schoolmates and friends. We conducted a multicenter cross-sectional study to investigate the association between school environment factors and adolescents’ drinking behavior in China. Using multistage stratified cluster sampling, the study investigated 27,762 middle school students from six cities in China. The logistic regression model was used to explore the association between the school environment and adolescent alcohol drinking behaviors after adjusting for confounders, including gender, age, city, location, and smoking status. Compared with students with none of their close friends drinking, students with more than half of their close friends drinking were more likely to drink in a year (OR = 20.148, 95% CI: 17.722−22.905, p < 0.001) and in a month (OR = 13.433, 95% CI: 11.779−15.319, p < 0.001). In addition, classmates’ drinking behaviors, friends’ persuasion, and attending parties were risk factors for adolescents’ drinking behavior, while the propaganda and regulations of banning drinking in school were protective factors. The school environment, especially friends drinking, is associated with students’ drinking behavior. It is necessary to mobilize the strength of schools and peers to strengthen the prevention and control of adolescent drinking.

SnackTrack-An App-Based Tool to Assess the Influence of Digital and Physical Environments on Snack Choice

As food choices are usually processed subconsciously, both situational and food environment cues influence choice. This study developed and tested a mobile app to investigate the association between physical and digital environments on snack choices. SnackTrack was designed and used to collect data on the snack choices of 188 users in real-life settings during an 8-week feasibility trial. The app asks users to take a photo of the food they are planning to consume and to provide additional information regarding the physical environment and context in which this food was eaten. The app also displayed various user interface designs (i.e., different background images) to investigate the potential effects of images on snack choice. Preliminary results suggest that the time of snack obtainment did not have a significant effect on the healthfulness of the snacks chosen. Conversely, it was found that unhealthy background images appeared to encourage healthier snack choices. In conclusion, despite consumers having the knowledge to make healthy choices, environmental cues can alter food choices. SnackTrack, a novel tool to investigate the influence of physical and digital environments on consumers' food choices, provides possibilities for exploring what encourages (un)healthy eating behaviours.

Retail Food Environment around Schools in Barcelona by Neighborhood Socioeconomic Status: Implications for Local Food Policy

Childhood obesity is a relevant public health problem. The school food environment has been identified as an important factor for promoting healthy eating behaviors. This study assessed the availability of and proximity to unhealthy food stores around schools (n = 22) in the city of Barcelona and its association with neighborhood socioeconomic status (NSES). We conducted this cross-sectional study between 2019 and 2020. First, we identified all food retailers (n = 153) within a 400-m buffer around each school and identified those selling unhealthy food products. Then, we used Poison regression models to measure the association between NSES and the healthy food availability index (HFAI), adjusting for population density and distance. A total of 95% of the food establishments studied were classified as unhealthy (n = 146). In all, 90% of schools that had, at least, two unhealthy retailers in their proximity. There were significant differences in the mean distance to unhealthy establishments according to neighborhood SES and population density (p < 0.05). We found a positive association between schools located in higher SES neighborhoods and a higher availability and affordability of healthy food products (IIR = 1.67, 95% CI = 1.45−1.91 p = 0.000). We found strong social inequalities in the supply of healthy foods in Barcelona. Local food policy interventions addressing retail food environment around schools should consider socioeconomic inequalities.

[Changes in the neighborhood food environment and walking time among older adults: A longitudinal Japan Gerontological Evaluation Study (JAGES) between 2016 and 2019]

Objective　Maintaining or increasing walking provides several health benefits to older adults. However, the mid-term evaluation of Health Japan 21 [second term] showed that older adults' daily steps did not meet the goal. Therefore, this study emphasized primordial prevention, which is different from previous preventive approaches and focuses on the relationship between the built environment and physical activities, including daily steps. This study investigated the relationship between changes in the number of food stores and walking time.Methods　This longitudinal study utilized the self-administered mail survey data between 2016 and 2019 from the Japan Gerontological Evaluation Study (JAGES). Older adults aged ≥65 years and residing in 27 independent municipalities were recruited. The dependent variable was a change in the walking time at two-time points (increase or not). Our explanatory variable was the change in the number of food stores at two-time points, reported on a 5-point scale, including no store (reference), increased stores, store available, decreased stores, and I don't know. Equivalently, it was defined as the self-reported change in the number of food stores (stores that sell meats, fish, fruits, and vegetables) within the walking distance of participants' homes (within ～1 km) from 2016 to 2019. The covariates included demographic factors, health behavior factors, environmental factors, and health factors in 2016. We used Poisson regression analysis (5% significance level) to calculate the cumulative incidence rate ratio (CIRR) and 95% confidence interval (CI) for an increase in walking time compared to no increase in walking time. The multivariate normal imputation method supplemented missing data of the dependent variable, explanatory variable, and covariates. Additionally, respondents' answer of "other" for the covariates was supplemented.Results　Three years later, 13,400 (20.4%) respondents had increased their walking time. Older adults who reported increased number of stores (5,311, 8.1%) had more walking time than those who reported no stores (6,577, 10.0%) (CIRR=1.12; 95% CI: 1.03-1.21).Conclusion　Participants who reported an increase in the number of fresh food stores within the walking distance had 12% more walking time three years later. A built environment might be used to measure primordial prevention that increases the amount of walking in daily life. Our results may provide evidence for policymakers and stakeholders to consider healthy urban planning.

The Socio-Ecological Context of the Nutrition Transition in Indonesia: A Qualitative Investigation of Perspectives from Multi-Disciplinary Stakeholders

Background: Indonesia is undergoing a rapid nutrition transition—a shift in food consumption related to globalization, modernization, urbanization, and economic development—with potentially adverse impacts on diets, health, and the environment. This study sought to understand the perspectives of a multi-disciplinary group of experts on the effects of the nutrition transition on dietary behaviors, cardiovascular disease (CVD) risk factors, and the food environment in Indonesia. Methods: In-depth interviews were conducted online with 27 Indonesian experts, who are either healthcare providers, nutrition researchers, or environmental researchers. Interview question guides were developed based on a socio-ecological framework. We analyzed the data using deductive and inductive approaches. Results: Experts described a disconnect between awareness about and adherence to healthy diets among Indonesians. They highlighted a marked generational divide in food preferences between the younger population (<40y) and older population (40y+), due to the nutrition transition. Experts perceived that the nutrition transition has also resulted in more eating out, which promotes obesity, through the unhealthy menu offerings from restaurants. Experts also implied that traditional diets are no better than modern diets, due to unhealthy cooking practices, especially frying; suggesting that the combination of higher consumption of fast foods and unhealthy cooking practices may have worsened CVD risk factors in the population. Conclusion: Multi-disciplinary experts indicated that the nutrition transition has negatively impacted diets, health, and food environment in Indonesia. Our findings offer potential hypotheses that can be tested using quantitative approaches, to inform policy and the design of programs to reduce the adverse impacts of the nutrition transition in Indonesia.

Association between healthy food environment and metabolic syndrome, waist circumference, and systolic blood pressure in older adults in Southern Brazil

The aim of this study was to investigate the association between healthy food outlet proximity, metabolic syndrome (MS), and two of its components, waist circumference (WC) and systolic blood pressure (SBP), in older adults (63-107 years old, median age 73 years) living in Florianópolis, South Brazil in 2013-2014. This is a cross-sectional analysis of the second wave of the EpiFloripa Aging Cohort Study. Individual-level data on MS, WC, SBP, and socio-demographic and health-related characteristics were collected from face to face interviews. The healthy food environment was assessed via the number and types of establishments present. The residences of older adult participants were georeferenced using Geographical Information System (GIS) software. The number of each type of food establishment in a 500 m buffer around the each residence was determined. Multivariate linear regression was used to test association between food outlet proximity and continuous outcomes (SBP and WC), and multiple logistic regression was used to examine the relations between the predictor variables and the dichotomous outcome of MS (yes/no). The study revealed that greater frequency of supermarkets and restaurants in the neighborhood was associated with a lower likelihood of having MS. WC was lower in individuals living in places with greater availability of greengrocers' shops and restaurants. The results demonstrated that the number of establishments in a neighborhood is associated with cardiometabolic outcomes, and the likelihood of MS and increased WC is lower for older adults who live in neighborhoods with more access to establishments that sell foundational components of a healthy diet.

What Is Associated with Changes in Food Security among Low-Income Residents of a Former Food Desert?

Lack of geographic access to foods has been postulated as a cause for food insecurity, which has been linked to poor nutrition, obesity, and chronic disease. Building on an established cohort of randomly selected households from a low-income, predominantly Black neighborhood, we examined household food security, distance to where study participants reported doing their major food shopping, and prices at stores where they shopped. Data from the Pittsburgh Hill/Homewood Research on Eating, Shopping, and Health study for years 2011, 2014 and 2018 was limited to residents of the neighborhood that began as a food desert (i.e., low access to healthy foods), but acquired a full-service supermarket in 2013. We calculated descriptive statistics and compared study participants in the former food desert neighborhood whose food security improved to those whose food security did not improve across survey waves. We estimated cross sectional linear regressions using all waves of data to assess food security level among study participants. Distance to major food shopping store was positively associated with food security (p < 0.05) while food-store prices were not significantly associated with food security. Findings suggest that for predominantly low-income residents, food secure individuals traveled further for their major food shopping.

A Cross-Sectional Analysis of Food Perceptions, Food Preferences, Diet Quality, and Health in a Food Desert Campus

The sensory properties of foods guide food choices and intake, importantly determining nutritional and health status. In communities that have inconsistent access to nutritious foods, such as food deserts, food taste perceptions and preferences have yet to be explored. The purpose of this study was to examine how taster status (supertaster vs. non-taster) and food security status (high or marginal vs. low or very low) influences food taste intensities, food preferences and perceptions, and diet quality in a cohort of students from a food desert campus in the Central Valley of California. Moreover, the complex relationship of socioeconomic status, race/ethnicity, and sex on cardiometabolic and cognitive health warrants further examination. Two hundred fifty participants (aged 18-24 years) living in a food desert campus were recruited in 2018 for this cross-sectional study where participants underwent taste tests on selected fruits, vegetables, and nuts, and clinical tests (anthropometrics, blood glucose, blood pressure, and endothelial function), cognitive function tests (memory and attention), diet quality assessment (Healthy Eating Index (HEI)), and food preference and perception assessments. Food taste intensities were influenced by sex with bitter and umami taste intensities of several foods being perceived more intensely by males. Moreover, food liking was largely influenced by ethnicity with Hispanics having higher liking ratings for several foods compared with non-Hispanics. Both, Hispanics and females, had higher total fruit HEI scores and lower attention scores than non-Hispanics and males, respectively. Females also had lower blood pressure, reactive hyperemia index, and fasting blood glucose. Food-insecure individuals rated cost and convenience as more important factors for overall food consumption and had lower attention scores than those with higher food-security status. Future research should consider the complex interactions of factors such as taste and flavor perception, sex, ethnicity, prior exposure to foods, and other environmental factors when studying food preferences and health in young adults.
