【 摘 要 】

Objectives: The goal of this research was to assess the roles of demographic and home food environment characteristics on diet quality measured with the U.S. Department of Agriculture's Healthy Eating Index (HEI) in a population of low-income overweight and obese African American women.Design: Cross-sectional analysis of baseline data.Setting: A community-based study of low-income overweight and obese African American women.Subjects: Participants enrolled in the Healthy Homes/Healthy Families study including a home environment survey (e.g., food availability, food practices and social support) and 24-hour recall dietary data collected on one weekday and one weekend day (n = 198).Results: In multivariate regression analyses, demographic characteristics were not significantly associated with diet quality; however, several home food environment characteristics were significantly associated with higher quality diets, including healthy shopping (e.g., regularly purchasing fresh fruits and vegetables), selecting healthy beverages (e.g., without added sugar), healthy food preparation, and serving behaviors. Eating while watching television was associated with lower quality diets. Nearly 33% (p < 0.001) of the variance in HEI total score was explained by the home food environment factors, far surpassing that explained by demographic characteristics (3.5%, p = 0.21).Conclusions: Interventions targeting the home food environment may improve overall diet quality in low-income overweight African American populations.
