Introduction:
The food environment, including food retail venues, has been shown to be associated with diet, and many disadvantaged neighborhoods lack access to high quality and affordable healthy foods. Research has sought to understand whether and how the food retail environment influences diet, and it is possible that shopping at different types of stores (e.g. full-service vs discount grocery store) influences diet and self-reported health outcomes. There is limited understanding of whether factors of the food environment and primary shopping location impact cardiometabolic health (blood pressure, HbA1c, cholesterol) and self-rated health.
Methods:
We report on 459 individuals who participated in a blood draw in 2018 as part of the Pittsburgh Hill/Homewood Research on Eating, Shopping, and Health, a longitudinal natural-experiment study among African American adults from two socioeconomically similar neighborhoods. Participants reported their perceived access to fruit and vegetables within their neighborhood and where they did their primary food shopping. Outcomes include measured height, weight, blood pressure, cholesterol (HDL, Total), HbA1c, and participant’s self-rated health. We employed logistic regression to examine associations between 1) perceived fruit and vegetable availability, quality, and price and 2) primary food shopping store type and reason for shopping there, with cardiometabolic and self-rated health outcomes. Covariates were neighborhood, years lived in neighborhood, age, race, income, education, and marital status.
Results:
Participants were on average, 60.7 years old (SD=13.9); 81.7% (375 of 459) female; 80.4% (369 of 459) overweight/obese. After covariate adjustment, both more perceived accessibility of purchasing (OR: 0.47, 95% CI: 0.28, 0.79) and pricing of fruits and vegetables (OR: 0.59, 95% CI: 0.36, 0.96) within one’s neighborhood were associated with lower odds of high blood pressure. More accessible purchasing (OR: 0.59, 95% CI: 0.39, 0.90), pricing (OR: 0.62, 95% CI: 0.41, 0.94), and higher quality of fruits and vegetables (OR: 0.64, 95% CI: 0.42, 0.97) within one’s neighborhood were associated with lower odds of poor self-rated health. Doing one’s primary food shopping at a discount grocery store compared to a full-service grocery store was associated with lower odds of being overweight (OR: 0.51, 95% CI: 0.26, 0.99). Choosing a primary food store based on price rather than quality of food was associated with increased odds of high cholesterol (OR: 2.02, 95% CI: 1.19, 3.45).
Conclusion:
These results suggest that higher perceptions of access to fruits and vegetables in one’s neighborhood and choice of primary food shopping store are important correlates of cardiometabolic health. Further research should look towards understanding how direct food choices made at stores impact cardiometabolic outcomes within this population.
