Abstract
OBJECTIVES We systematically evaluated changes in availability, price, and quality of perishable food items from the beginning to the end of the month in lowincome, urban neighborhoods. METHODS The sample included grocery stores or supermarkets in Cleveland, Ohio, within neighborhoods with >30% of population receiving food assistance. We collected data for 2 sequential months during the first and fourth weeks of each month. Two coders evaluated stores, collecting measures of availability, price, and quality for 50 items. We examined difference in number and proportion of items available at the beginning of the month (BOM) to items remaining available at the end of the month (EOM), as well as quality and price of those items. RESULTS Across 48 stores, availability at EOM was lower than BOM; as store size increased, reduction in availability (ie, food melt) was significantly (p < .01) less pronounced. Overall, items became less expensive at the EOM whereas quality remained consistent; we noted no statistically significant differences by store type for price or quality. CONCLUSIONS Food melt differentially affects individuals in neighborhoods without grocery stores. Findings reveal composition of food environments is dynamic rather than static, influencing food-purchasing choices among lowincome consumers.

Abstract
Food marketing environments of Black American consumers are heavily affected by ethnically-targeted marketing of sugar sweetened beverages, fast foods, and other products that may contribute to caloric overconsumption. This qualitative study assessed Black consumers' responses to targeted marketing. Black adults (2 mixed gender groups; total n = 30) and youth (2 gender specific groups; total n = 35) from two U.S. communities participated before and after a sensitization procedure-a critical practice used to understand social justice concerns. Pre-sensitization focus groups elicited responses to scenarios about various targeted marketing tactics. Participants were then given an informational booklet about targeted marketing to Black Americans, and all returned for the second (post-sensitization) focus group one week later. Conventional qualitative content analysis of transcripts identified several salient themes: seeing the marketer's perspective ("it's about demand"; "consumers choose"), respect for community ("marketers are setting us up for failure"; "making wrong assumptions"), and food environments as a social justice issue ("no one is watching the door"; "I didn't realize"). Effects of sensitization were reflected in participants' stated reactions to the information in the booklet, and also in the relative occurrence of marketer-oriented themes and social justice-oriented themes, respectively, less and more after sensitization.

Abstract
OBJECTIVES The residential neighbourhood fast-food environment has the potential to lead to increased levels of obesity by providing opportunities for residents to consume energy-dense products. This longitudinal study aimed to examine whether change in body mass index (BMI) differed dependent on major chain fast-food outlet availability among women residing in disadvantaged neighbourhoods. SETTING Eighty disadvantaged neighbourhoods in Victoria, Australia. PARTICIPANTS Sample of 882 women aged 18-46 years at baseline (wave I: 2007/2008) who remained at the same residential location at all three waves (wave II: 2010/2011; wave III: 2012/2013) of the Resilience for Eating and Activity Despite Inequality study. PRIMARY OUTCOME BMI based on self-reported height and weight at each wave. RESULTS There was no evidence of an interaction between time and the number of major chain fast-food outlets within 2 (p=0.88), 3 (p=0.66) or 5 km (p=0.24) in the multilevel models of BMI. Furthermore, there was no evidence of an interaction between time and change in availability at any distance and BMI. CONCLUSIONS Change in BMI was not found to differ by residential major chain fast-food outlet availability among Victorian women residing in disadvantaged neighbourhoods. It may be that exposure to fast-food outlets around other locations regularly visited influence change in BMI. Future research needs to consider what environments are the key sources for accessing and consuming fast food and how these relate to BMI and obesity risk.

Baseline Assessment of a Healthy Corner Store Initiative: Associations between Food Store Environments, Shopping Patterns, Customer Purchases, and Dietary Intake in Eastern North Carolina. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2017; 14:E1189.

Abstract
In 2016, the North Carolina (NC) Legislature allocated $250,000 to the NC Department of Agriculture, to identify and equip small food retailers to stock healthier foods and beverages in eastern NC food deserts (the NC Healthy Food Small Retailer Program, HFSRP). The purpose of this study was to examine associations between food store environments, shopping patterns, customer purchases, and dietary consumption among corner store customers. We surveyed 479 customers in 16 corner stores regarding demographics, food purchased, shopping patterns, and self-reported fruit, vegetable, and soda consumption. We objectively assessed fruit and vegetable consumption using a non-invasive reflection spectroscopy device to measure skin carotenoids. We examined associations between variables of interest, using Pearson's correlation coefficients and adjusted linear regression analyses. A majority (66%) of participants were African American, with a mean age of 43 years, and a mean body mass index (BMI) of 30.0 kg/m². There were no significant associations between the healthfulness of food store offerings, customer purchases, or dietary consumption. Participants who said they had purchased fruits and vegetables at the store previously reported higher produce intake (5.70 (4.29) vs. 4.60 (3.28) servings per day, p = 0.021) versus those who had not previously purchased fresh produce. The NC Legislature has allocated another $250,000 to the HFSRP for the 2018 fiscal year. Thus, evaluation results will be important to inform future healthy corner store policies and initiatives.

Abstract
Background: The global obesity pandemic and rates of nutrition-related noncommunicable diseases (NCDs) have increased worldwide, especially in the Latin American and Caribbean region. In an attempt to control this obesity epidemic, the Chilean government has established a comprehensive set of regulatory actions, including beverage taxation, warning labels on foods, and marketing restrictions to children. To improve the effectiveness of actions to prevent obesity, a better understanding of the food environment is needed. Objective: We developed and standardized photographic methods to assess and monitor packaged food and beverage products in supermarkets. Methods: A standardized protocol and food categorization system was used to guide photo collection and data management of photos taken between February and April 2015 in 11 supermarkets, consisting of 5 different supermarket chains, from high- (n = 6) and lower-middle (n = 5)-income neighborhoods in Santiago, Chile. Photos (n = ∼50,000) from nearly 10,000 unique food products from high- and lower-middle-income neighborhoods were used for this study. Results: We developed standardized methods to use photographs to assess and monitor the food environment. A food categorization scheme is essential to guiding the data collection process. Substantial time and human resources are required to assess packaged food and beverage products in supermarkets. Because the number of photos per food product is variable, the organization of the photographs according to the food categorization system, before data entry, is imperative for easy access during data entry and analysis. We identified the information necessary for a photographic registry, which, with the food categorization system, is critical to create unique identifiers that are linked to each food product and its photos. Conclusions: To adequately monitor food environments, standardized methods for food photo collection and management are essential. The information collected on food package photos to monitor food environments is important for guiding and evaluating actions in the context of the ongoing obesity and NCD epidemics.

Abstract
Policy Points: On-shelf nutrition labelling systems in supermarkets, such as the Guiding Stars system, are intended to provide consumers with simple, standardized nutrition information to support more informed and healthier food choices. Policies that support the provision of simplified nutrition labelling systems may encourage consumers to make positive shifts in food-purchasing behaviors. The shifts in consumer food-purchasing patterns observed in our study after the introduction of the Guiding Stars system in supermarkets translated into measurable nutritional benefits, including more items purchased with slightly less trans fat and sugar and more fiber and omega-3 fatty acids. This study is one of the first to report the positive impact of an on-shelf nutrition labelling system on supermarket sales and revenues-key information that was specifically requested by the US National Academies, as such labelling interventions may be more sustainable if they lead to higher revenues. CONTEXT Providing a nutrition rating system on the front of food packages or on retail shelf tags has been proposed as a policy strategy for supporting healthier food choices. Guiding Stars is an on-shelf nutrition labelling system that scores foods in a supermarket based on nutritional quality; scores are then translated into ratings of 0 to 3 stars. It is consistent with evidence-informed recommendations for well-designed labels, except for not labelling 0-star products. The largest supermarket retailer in Canada rolled out the Guiding Stars system in supermarkets across Ontario, Canada. The aim of our study was to examine the extent to which consumers respond to an on-shelf nutrition labelling system in supermarkets to inform current and future nutrition labelling policies and practices. METHODS Capitalizing on a natural experiment, we conducted a quasi-experimental study across 3 supermarket banners (or "chains") in Ontario, one of which implemented the Guiding Stars system in 2012. We used aggregated supermarket transaction data to test the effect of Guiding Stars on the nutritional quality of food purchases in intervention supermarkets relative to control supermarkets. We also conducted exit surveys among 783 randomly selected shoppers from intervention and control supermarkets to assess consumer awareness, understanding, trust, and self-reported use of the labelling system. FINDINGS Relative to control supermarkets, shoppers in intervention supermarkets made small but significant shifts toward purchasing foods with higher nutritional ratings; however, shifts varied in direction and magnitude across food categories. These shifts translated into foods being purchased with slightly less trans fat and sugar and more fiber and omega-3 fatty acids. We also found increases in the number of products per transaction, price per product purchased, and total revenues. Results of the exit surveys indicate a modest proportion of consumers were aware of, understood, and trusted Guiding Stars in intervention supermarkets, and a small proportion of consumers reported using this system when making purchasing decisions. However, 47% of shoppers exposed to Guiding Stars were confused when asked to interpret the meaning of a 0-star product that does not display a rating on the shelf tag. CONCLUSIONS This study demonstrates support for policies promoting on-shelf nutrition labels designed according to evidence-informed principles, but policymakers should move forward with caution when investing in such systems until research has confirmed optimal label design, clarified the mechanisms through which dietary intake is improved, and assessed associations with nutrition-related health outcomes.

Abstract
There is much ongoing research about the effect of the urban environment as compared with individual behaviour on growing obesity levels, including food environment, settlement patterns (e.g., sprawl, walkability, commuting patterns), and activity access. This paper considers obesity variations between US counties, and delineates the main dimensions of geographic variation in obesity between counties: by urban-rural status, by region, by area poverty status, and by majority ethnic group. Available measures of activity access, food environment, and settlement patterns are then assessed in terms of how far they can account for geographic variation. A county level regression analysis uses a Bayesian methodology that controls for spatial correlation in unmeasured area risk factors. It is found that environmental measures do play a significant role in explaining geographic contrasts in obesity.

Abstract
Obesity is a global pandemic that brings about a myriad of health consequences. In the past, policies for combating obesity mainly focused on improving individual health and behavior, but nowadays some policies have changed and now concentrate on improving the built environment believing this can improve health through positive changes to health-related behaviors. We examined whether both individual and environmental factors were associated with body mass index in Seoul, the capital city of South Korea. Data from the 2011 and 2013 Community Health Surveys were used (n = 20,147 men and 25,300 women). We staged multilevel logistic regression models to estimate the effect of individual and environmental factors on obesity. Among individual covariates, high-risk drinking, the time spent watching TV and surfing the Internet, high salt intake, stress, and the negative recognition of health were significantly associated with obesity. When controlling individual covariates, the number of sports facilities, number of fried chicken stores, and food insecurity level were statistically associated with probability of obesity. Therefore, this study emphasizes that it is important not only to improve the health behavior of the individual, but also to improve the urban environment in order to reduce the obesity rates of city dwellers.

Is Living near Healthier Food Stores Associated with Better Food Intake in Regional Australia? INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2017; 14:ijerph14080884.

Abstract
High prevalence of obesity and non-communicable diseases is a global public health problem, in which the quality of food environments is thought to play an important role. Current scientific evidence is not consistent regarding the impact of food environments on diet. The relationship between local food environments and diet quality was assessed across 10 Australian suburbs, using Australian-based indices devised to measure the two parameters. Data of dietary habits from the participants was gathered using a short questionnaire. The suburbs' Food Environment Score (higher being healthier) was associated with higher consumption of fruit (χ² (40, 230) = 58.8, p = 0.04), and vegetables (χ² (40, 230) = 81.3, p = 0.03). The Food Environment Score identified a significant positive correlation with four of the diet scores: individual total diet score (rs = 0.30, p < 0.01), fruit and vegetable score (rs = 0.43, p < 0.01), sugary drink score (rs = 0.13, p < 0.05), and discretionary food score (rs = 0.15, p < 0.05). Moreover, the suburbs' RFEI (Retail Food Environment Index, higher being unhealthier) showed a significant association with higher consumption of salty snacks (χ² (24, 230) = 43.9, p = 0.04). Food environments dominated by food outlets considered as 'healthier' were associated with healthier population food intakes, as indicated by a higher consumption of fruit, vegetables, and water, as well as a lower consumption of junk food, salty snacks, and sugary drinks. This association suggests that healthier diet quality is associated with healthier food environments in regional Australia.

Abstract
We assessed community residents' perceptions of corner stores to better understand what facilitates and deters patronage at these food outlets. Data came from 978 household interviews in 2 Latino communities undergoing corner store interventions. Chi-square tests, an independent sample t test, and a multivariate logistic regression were conducted to assess the relationship between residents' perceptions about corner stores and their reported patronage at these food outlets. Residents reported that corner stores do not sell a variety of fruits and vegetables and are not places where one can get information about healthy eating. Convenience, cleanliness, positive customer service, availability of culturally appropriate items, and availability of quality fresh fruit increased the odds of store patronage. Simply providing healthy foods will not incentivize patrons to purchase them. Corner store interventions can be more effective if they address the characteristics that community residents prioritize.

Abstract
Research linking characteristics of the neighborhood environment to health has relied on traditional regression methods where prespecified distances from participant's locations or areas are used to operationalize neighborhood-level measures. Because the relevant spatial scale of neighborhood environment measures may differ across places or individuals, using prespecified distances could result in biased association estimates or efficiency losses. We use novel hierarchical distributed lag models and data from the Multi-Ethnic Study of Atherosclerosis (MESA) to (1) examine whether and how the association between the availability of favorable food stores and body mass index (BMI) depends on continuous distance from participant locations (instead of traditional buffers), thus allowing us to indirectly infer the spatial scale at which this association operates; (2) examine if the spatial scale and magnitude of the association differs across six MESA sites, and (3) across individuals. As expected, we found that the association between higher availability of favorable food stores within closer distances from participant's residential location was stronger than at farther distances, and that the magnitude of the adjusted association declined quickly from zero to two miles. Furthermore, between-individual heterogeneity in the scale and magnitude of the association was present; the extent of this heterogeneity was different across the MESA sites. Individual heterogeneity was partially explained by sex. This study illustrated novel methods to examine how neighborhood environmental factors may be differentially associated with health at different scales, providing nuance to previous research that ignored the heterogeneity found across individuals and contexts.

Abstract
Associations between neighborhood food environment and adult body mass index (BMI; weight (kg)/height (m)2) derived using cross-sectional or longitudinal random-effects models may be biased due to unmeasured confounding and measurement and methodological limitations. In this study, we assessed the within-individual association between change in food environment from 2006 to 2011 and change in BMI among adults with type 2 diabetes using clinical data from the Kaiser Permanente Diabetes Registry collected from 2007 to 2011. Healthy food environment was measured using the kernel density of healthful food venues. Fixed-effects models with a 1-year-lagged BMI were estimated. Separate models were fitted for persons who moved and those who did not. Sensitivity analysis using different lag times and kernel density bandwidths were tested to establish the consistency of findings. On average, patients lost 1 pound (0.45 kg) for each standard-deviation improvement in their food environment. This relationship held for persons who remained in the same location throughout the 5-year study period but not among persons who moved. Proximity to food venues that promote nutritious foods alone may not translate into clinically meaningful diet-related health changes. Community-level policies for improving the food environment need multifaceted strategies to invoke clinically meaningful change in BMI among adult patients with diabetes.

Abstract
INTRODUCTION One third of the approximately 23,000 undergraduates in the United States are overweight or obese. College students appear to be more vulnerable to disproportionate weight gain during this time. METHOD Cross-sectional. Diet, body mass index, and appetitive responsiveness were assessed in 80 undergraduates enrolled in three different meal plans, unlimited access, points, and none. RESULTS Appetitive responsiveness was positively correlated with fat (r = 0.34, p = .002) but not added sugars across groups. Unlimited access-plan students had higher fat consumption than no-plan students, regardless of appetitive responsiveness. Unlimited access-plan students had higher fruit and vegetable consumption and higher dairy consumption than point-plan students. There were no group differences for body mass index. All groups were below the U.S. Department of Agriculture guidelines for dairy and fruit and vegetable intake. DISCUSSION Optimizing the college campus food environment toward healthful, affordable choices is likely to improve dietary habits and might minimize college weight gain.

Abstract
Geographic information systems (GIS) data/methods offer good promise for public health programs including obesity-related research. This study systematically examined their applications and identified gaps and limitations in current obesity-related research. A systematic search of PubMed for studies published before 20 May 2016, utilizing synonyms for GIS in combination with synonyms for obesity as search terms, identified 121 studies that met our inclusion criteria. We found primary applications of GIS data/methods in obesity-related research included (i) visualization of spatial distribution of obesity and obesity-related phenomena, and basic obesogenic environmental features, and (ii) construction of advanced obesogenic environmental indicators. We found high spatial heterogeneity in obesity prevalence/risk and obesogenic environmental factors. Also, study design and characteristics varied considerably across studies because of lack of established guidance and protocols in the field, which may also have contributed to the mixed findings about environmental impacts on obesity. Existing findings regarding built environment are more robust than those regarding food environment. Applications of GIS data/methods in obesity research are still limited, and related research faces many challenges. More and better GIS data and more friendly analysis methods are needed to expand future GIS applications in obesity-related research.

Abstract
BACKGROUND The first 2 years of life are instrumental for childhood physical development. Factors contributing to childhood obesity are difficult to determine; child care exposure is one to consider, by influencing food preference and physical activity development. OBJECTIVE To investigate the association of child care exposure with adiposity at 2 years. METHODS Data were collected as part of the secondary analysis of the prospective ROLO study (randomized control trial of low glycemic index diet) in Dublin, Ireland. Mothers were recruited antenatally and followed up at 2 years postpartum. Maternal and childhood anthropometric data and lifestyle questionnaires, reporting on child care attendance (defined as nonparental care), exposure (weeks), and infant-feeding practices, were collected. RESULTS Anthropometric measures and lifestyle data were collected for 273 mothers and children aged 2 years, 52.7% of whom attended child care. Child care was predominately provided by a nonrelative (83.7%), either in a crèche (57%) or by a childminder (26.7%). More than half (56.2%) of the children attended child care part-time (≤30 hours/week). Central adiposity measures (abdominal circumference, waist:height ratio) and total adiposity (sum of all skin folds) were significantly elevated in children with increasing time in child care. Children provided with "meals and snacks" had elevated adiposity measures versus those given "snacks or no food." No difference in the infant-feeding practices was identified between the child care groups. CONCLUSIONS Children attending child care have higher total and central adiposity, proportional to exposure. More research is required to investigate this link to appropriately design health promotion and obesity prevention programs targeting children at 2 years.

Abstract
INTRODUCTION Blacks, Hispanics, and women of lower socioeconomic status tend to have a higher risk of obesity. Numerous studies over the past decade examined the role of the neighborhood food environment in body weight. However, few were longitudinal. PURPOSE This longitudinal study examined whether multiple measures of neighborhood food availability were associated with body mass index (BMI) in a predominately Black and Hispanic adult sample living in low- to moderate-income urban neighborhoods. METHOD This longitudinal study used two waves of data (2002, 2008), including interviewer-measured height and weight, from a community survey of adults ( n = 219). In both 2002 and 2008, multiple measures characterized neighborhood food availability: GIS-derived availability of retail food outlets (large grocery store, small grocery store, convenience store, liquor stores), observed fruit and vegetable availability (count of stores selling 10 or more fresh fruit or vegetable varieties), and perceived fruit and vegetable access. Random intercept models estimated multivariable associations, controlling for individual-level demographics and neighborhood median household income. RESULTS Small grocery store availability was associated with 1.22-unit increase in BMI ( p = .047), while each unit increase in perceived fruit and vegetable access was associated with a 0.69-unit decrease in BMI ( p = .055). BMI was not associated with large grocery store, convenience store, or liquor store availability, or with observed fruit and vegetable availability. CONCLUSIONS Findings suggest that improving the neighborhood food environment, particularly at small grocery stores, may help urban residents living in low- to moderate-income neighborhoods achieve healthier body weights over time.

Abstract
OBJECTIVE To investigate reasons why parents purchase prepackaged, processed meals and associations with parental cooking self-efficacy, meal-planning ability, and home food availability. METHODS This secondary data analysis uses Healthy Home Offerings via the Mealtime Environment Plus study data from parents of children aged 8-12 years (n = 160). Associations between reasons why parents purchase prepackaged, processed meals and the outcomes were assessed with chi-square, Fisher exact, and t tests. RESULTS The most frequently endorsed reasons for purchasing prepackaged, processed meals included lack of time (57%) and family preferences (49%). Five of 6 reasons were associated with lower parental cooking self-efficacy and meal-planning ability. Some reasons were associated with less-healthful home food environments; few reasons varied by socio-demographic characteristics. CONCLUSIONS AND IMPLICATIONS Because lower cooking self-efficacy and meal-planning ability are associated with most reasons reported for purchasing prepackaged, processed meals, strategies to increase these attributes for parents of all backgrounds may reduce reliance on prepackaged processed meals for family mealtimes.

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

Abstract
PURPOSE To develop a valid and feasible short-form corner store audit tool (SCAT) that could be used in-store or over the phone to capture the healthfulness of corner stores. DESIGN Nonexperimental. SETTING Four New Jersey cities. SUBJECTS Random selection of 229 and 96 corner stores in rounds 1 and 2, respectively. MEASURES An adapted version of the Nutrition Environment Measures Survey for Corner Stores (NEMS-CS) was used to conduct in-store audits. The 7-item SCAT was developed and used for round 2 phone audits. ANALYSIS Exploratory factor analysis and item response theory were used to develop the SCAT. RESULTS The SCAT was highly correlated with the adapted NEMS-CS ( r = .79). Short-form corner store audit tool scores placed stores in the same healthfulness categories as did the adapted NEMS-CS in 88% of the cases. Phone response matches indicated that store owners did not distinguish between 2% and low-fat milk and tended to round up the fruit and vegetable count to 5 if they had fewer varieties. CONCLUSION The SCAT discriminates between higher versus lower healthfulness scores of corner stores and is feasible for use as a phone audit tool.

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

Abstract
OBJECTIVE To describe the adaptation and inter-rater reliability assessment of the Toronto Nutrition Environment Measures Survey-Store. METHODS A total of 55 food stores (2 bakeries, 2 dollar stores, 19 gas/convenience stores, 18 grocery stores, 4 pharmacies, 8 specialty stores, and 2 superstores) were assessed in 2014. Cohen's kappa and intra-class correlation coefficients (ICC) were assessed for inter-rater reliability for product availability, price, quality, ethno-cultural accessibility scores, and overall store scores. RESULTS Inter-rater reliability was high for availability (average kappa = 0.91), price (average ICC = 0.964), ethno-cultural accessibility score (ICC = 0.981), and overall store scores (ICC = 0.991). CONCLUSIONS AND IMPLICATIONS Measures in the Toronto Nutrition Environment Measures Survey-Store demonstrated excellent inter-rater agreement. Limited access to fruits and vegetables and ethno-cultural foods are related to diet-related chronic diseases, particularly among immigrants. Findings of the study may be useful in guiding public health programming.

Abstract
INTRODUCTION Supermarkets are a major source of food for many families. Knowledge of how educational attainment affects the relationship between in-store environments of supermarkets and diet is needed. This study examined the relationship between maternal dietary quality and overall in-store supermarket environment, and assessed the effect modification of educational attainment. METHODS Dietary quality z-scores were calculated for 829 mothers with young children using cross-sectional data collected in 2010-2011 from a 20-item food frequency questionnaire. Information about nine in-store factors (variety, price, quality, promotion, shelf placement, store placement, nutrition information, healthier alternatives, and single fruit sale) on 12 foods known to discriminate between better and poorer dietary quality were collected to create a standardized "healthfulness" z-score for each supermarket where mothers shopped. RESULTS Multilevel unadjusted linear regression analysis completed in 2014-2015 showed that shopping at more-healthful supermarkets was associated with better dietary quality (β=0.39 SD/SD, p=0.01, 95% CI=0.10, 0.68). However, the relationship differed according to educational attainment (interaction, p=0.006). Among mothers who left school at age 16 years, those who shopped at less healthful supermarkets had poorer dietary quality (β=0.31 SD/SD, 95% CI=0.07, 0.55). Among mothers with degrees, those who shopped at less healthful supermarkets had better dietary quality (β=-0.59 SD/SD, 95% CI=-1.19, 0.00). CONCLUSIONS Mothers with low educational attainment show greater susceptibility to less healthful in-store environments than mothers with higher educational attainment who may be protected by greater psychological and financial resources. Policy initiatives to improve supermarket environments may be necessary to address dietary inequalities.

Abstract
Characteristics of the built environment, including access to unhealthy food outlets, are hypothesized to contribute to type 2 diabetes mellitus (T2D). Swedish nationwide registry data on 4,718,583 adults aged 35-80 years living in 9,353 neighborhoods, each with at least 1 food outlet, were geocoded and linked to commercial registers (e.g., restaurants and grocery stores). Multilevel logistic regression was used to examine the prospective relationship between characteristics of the food environment and T2D from 2005 to 2010. Relative access to health-harming food outlets was associated with greater likelihood of both prevalent and incident T2D in a curvilinear manner, with the highest risk being observed for environments in which one-third of outlets were health-harming. Relative to individuals whose food environment did not change, those who moved into areas with more health-harming food outlets had higher odds of developing T2D (odds ratio = 3.67, 95% confidence interval: 2.14, 6.30). Among those who did not move, living in an area that gained relative access to health-harming food outlets was also associated with higher odds of T2D (odds ratio = 1.72, 95% confidence interval: 1.27, 2.33). These results suggest that local food environment, including changes that result in greater access to unhealthy food outlets, is associated with T2D.

Abstract
AIM To obtain expert consensus to develop and evaluate a rating system on the relative healthiness of Australian suburbs' food outlet types. METHODS Twenty-four food outlet types and 10 local suburbs were identified from previous mapping studies and based on a scan of suburbs across one large Australian geographical region. Initial food outlet 'scores' for relative healthiness were proposed based on available literature, classified into five categories, from 'most' to 'least' healthy. In round 1 of a modified Delphi survey, participants, Australian public health and nutrition experts, were given each outlet type's definition and the proposed scores and invited to modify the scores based on their perceived 'healthiness'. In round 2, participants were able to revise or adjust their scores. RESULTS Median scores for food outlet types from both rounds highly correlated with the originally proposed scores (two-tailed Pearson's correlation coefficient 0.97 and 0.96, respectively, P = 0.01), and scores from round 1 highly correlated with those from round 2 (Pearson's coefficient 0.998, P = 0.01). Round 2 scores were used to calculate suburbs' overall food environment score, healthiness score, unhealthiness score and a ratio of unhealthiness to healthiness scores. There was strong positive correlation between suburbs' ratio of unhealthiness to healthiness scores and a previously recognised scoring ratio, Retail Food Environment Index (Spearman's rho 0.847, P < 0.01). CONCLUSIONS The study generated experts' consensus about relative healthiness of food outlet types found in Australian neighbourhoods. Proposed scores can be used to assess and compare healthiness of community food environments and to explore their associations with area characteristics, population's diet and health outcomes.

Abstract
BACKGROUND Food behaviours are important in the context of health and obesity. The aim was to explore the environments and food behaviours of a sample of young people in the North East of England to further understanding of the relationship between eating behaviours and environmental context. METHODS Focus groups were conducted with four groups of young people aged 16-20 years (n = 40; 28 male, 12 female) between November 2006 and June 2007. Analysis was informed by grounded theory methods and was an iterative process of identifying themes across the transcripts. RESULTS Topics explored included: their main environment, home food responsibility and cooking, food outside of the home, where food was purchased/obtained and where food was eaten and with whom. Emergent themes included: the value for money in food purchases, time convenience, the car as a means of accessing food and health perceptions. CONCLUSIONS The complexities of the food environment were illustrated. This work has highlighted the importance of the home food environment and parents, and indicated the importance of factors such as time and cost in this age group's food choices. The behavioural norms around food behaviours merit further exploration for this population in transition between adolescence and adulthood.
