摘要：

Background: Residential food environment influences dietary patterns, however the impact of individuals' perceived social identity on their antioxidant intake, an indicator of healthy dietary patterns, remains underexplored. Objective: We conducted a cross-sectional analysis using data collected in a longitudinal cohort. In the study, we aimed to investigate the interactions between the food environment and two indicators of social identity, specifically a subjective ladder measure of socioeconomic status (SES) and the Multigroup Ethnic Identity Measure (MEIM) score, in relation to dietary antioxidant intake (DAI) among n = 512 Boston and NYC-resident pregnant women. Methods: The modified Retail Food Environment Index (mRFEI) was calculated using the Centers for Disease Control and Prevention's equation, with higher scores indicating a healthier food environment. DAI was estimated by summing standardized data from six micronutrients (magnesium, selenium, zinc, and vitamins A, C, and E) obtained through the Block98 Food Frequency Questionnaires administered during pregnancy, with higher scores indicating increased intake. The mRFEI and DAI were dichotomized based on a median split. Multivariable-adjusted logistic regressions were used to analyze associations, both with and without considering women's subjective SES or MEIM levels as effect modifiers. Results: Women were racially/ethnically mixed (19.2 % White, 42.7 % Black, and 33.1 % Hispanic) with 32.2 % reporting more than high school education. In the main effect models, no significant association was observed between mRFEI and DAI. Women with higher MEIM scores exhibited higher DAI [Odds ratio (OR) =1.85, 95 % Confidence interval (CI) = 1.26–2.73]. Exploratory interaction models showed that subjective SES significantly modified the association (p-value for interaction = 0.03), specifically, women perceiving themselves to have a lower SES compared to their community (n = 45) exhibited a significantly positive association between mRFEI and DAI. Conclusion: These findings suggest that women perceiving their SES to be lower than their neighborhoods may benefit from better access to healthy food. © 2024
