Neighborhood availability of convenience stores and diet quality: findings from 20 years of follow-up in the coronary artery risk development in young adults study.

ABSTRACT: We examined the association between neighborhood convenience stores and diet outcomes for 20 years of the Coronary Artery Risk Development in Young Adults study.We used dietary data from the Coronary Artery Risk Development in Young Adults study years 1985-1986, 1992-1993, and 2005-2006 (n?=?3299; Birmingham, AL; Chicago, IL; Minneapolis, MN; and Oakland, CA) and geographically and temporally matched neighborhood-level food resource and US Census data. We used random effects repeated measures regression to estimate associations between availability of neighborhood convenience stores with diet outcomes and whether these associations differed by individual-level income.In multivariable-adjusted analyses, greater availability of neighborhood convenience stores was associated with lower diet quality (mean score?=?66.3; SD?=?13.0) for participants with lower individual-level income (b?=?-2.40; 95% CI?=?-3.30, -1.51); associations at higher individual-level income were weaker. We observed similar associations with whole grain consumption across time but no statistically significant associations with consumption of sugar-sweetened beverages, artificially sweetened beverages, snacks, processed meats, fruits, or vegetables.The presence of neighborhood convenience stores may be associated with lower quality diets. Low-income individuals may be most sensitive to convenience store availability.

Project description:ObjectiveTo determine whether neighbourhood supermarket and convenience store availability and broader built environment context are associated with food purchasing behaviour in a national population.DesignWe used observational data to perform a cross-sectional study of food purchases for US households in 2010. We used three-level mixed-effect regression models to determine whether the associations between the number of neighbourhood supermarkets and convenience stores and the self-reported annual household expenditures for fruits and vegetables were affected by regional destination accessibility, neighbourhood destination diversity, availability of neighbourhood destinations and neighbourhood street connectivity.SettingMetropolitan statistical areas (n 378) in the USA.ParticipantsHouseholds (n 22 448).ResultsWhen we controlled for broader built environment context, there was no significant association between availability of neighbourhood supermarkets and expenditures on fruits and vegetables; instead, we observed an inverse association between the number of convenience stores and expenditures for fruits (P = 0·001). The broader built environment context was associated with food purchase, although the magnitude was small: (i) higher regional destination accessibility was associated with higher expenditures for fruits (P < 0·001); (ii) higher neighbourhood destination diversity was associated with lower expenditures for vegetables (P = 0·002); and (iii) higher neighbourhood street connectivity was associated with higher expenditures for fruits (P < 0·001).ConclusionsThe broader built environment factors contributed to understanding how people use neighbourhood food stores. However, there was only a small relationship between the broader environment context and fruit and vegetable expenditures. Policy interventions that focus exclusively on increasing the availability of neighbourhood supermarkets likely will not promote fruit and vegetable consumption.

Project description:IntroductionIn low-middle income countries, urbanization leads to changes from traditional to Western diet, which are often accompanied by reductions in cardiometabolic health. Whether socioeconomic status buffers these urbanization-related diet changes over time is unknown.ObjectiveTo examine whether the association between urbanization and a key indicator of Western diet, percent of calories from animal-source foods (1) varies depending on income and (2) whether this association changes over time.Materials and methodsWe used data from nine waves of the longitudinal, population-based China Health and Nutrition Survey [n = 22,360 Chinese adults (1991-2015)], followed across 24 years, including diet data from 3 repeated 24-h dietary recalls. We used simultaneous year-stratified linear regression models to examine whether changes in the association between urbanization level and percent of calories from animal-source foods differed by income. Models allowed for variation in associations across the 24 years of urbanization, accounting for within-individual correlation over time and controlling for age, sex, region, physical activity, and caloric intake.ResultsIn 1991, on average 15% of calories for Chinese adults came from animal source foods and by 2015, this percentage rose to approximately one quarter of total calories. Over the 24 years of follow-up, urbanization and income were each strongly related to percent of calories from animal-source foods with differential association across income levels (p < 0.0001). We also found evidence that this association changed over time (p < 0.0001). Income gradients in animal source food consumption were smallest in the most urban areas in early years with some temporal variation, but over time income gradients narrowed in some later years in low and moderately urbanized areas. However, by 2015 there were few income differences in animal source food consumption across urbanization levels.ConclusionsThroughout 24-years of urbanization, income seemed to buffer the transition from traditional to Western diet. However, the degree to which income buffered these urbanization-related changes depended on the level and history of community urbanization. At later stages of urbanization when Western diet behaviors were more widespread, urban-rural differences in Western diet behaviors varied little by income.

Project description:BACKGROUND:Food environments have rapidly changed over the past years in China and children have more access to unhealthy food in convenience stores near schools. Since the studies on the association between convenience stores near schools and obesity had inconsistent results and no similar study in China, we conducted a study on the association in Beijing of China, which will provide scientific evidence for the intervention of childhood obesity. METHODS:The study included 2201 students at grade 4 of 37 primary schools in Dongcheng or Miyun district of Beijing. The food environment data was acquired from AMAP, the free web-based geospatial service provider. The numbers of convenience stores were captured within the 800-m network buffer near schools using Geographic Information System. The weight and height of each student were measured by trained health professionals. Students' dietary and physical behaviors and other information associated with obesity were collected with questionnaires for students and their parents. The generalized linear mixed model (GLMM) was used to analyze the data. RESULTS:The average age of the students was 10.2?years (Standard Deviation (SD)?=?0.33). The prevalence of obesity in students was 14.9%. The median number of convenience stores within the 800-m network buffer near schools was 24 in two districts. The number of convenience stores near each school varied from 5 to 67 (median: 25) in Dongcheng district and from 1 to 57 (median: 22) in Miyun district. After adjusting for the confounding factors at the family and individual levels, the association between convenience stores and childhood obesity was statistically significant. Additional ten convenience stores near schools were associated with an increased risk of obesity (Odds Ratio (OR)?=?1.13, 95% confidence interval (CI): 1.03,1.24, P?=?0.011). Compared with less than 24 convenience stores near schools, the students with more than or equal to 24 convenience stores near schools had an increased risk of obesity (OR?=?1.49, 95% CI: 1.09, 2.03, P?=?0.013). CONCLUSION:The students with more convenience stores near their schools had an increased risk of obesity. The findings provided evidence for developing public health policy to restrict the number of convenience stores near schools to prevent and control childhood obesity.
