Abstract

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.

摘要

背景

居住环境会影响饮食模式，然而个体感知到的社会身份对其抗氧化剂摄入量（健康饮食模式的一个指标）的影响仍未得到充分探索。

目的

我们使用纵向队列中收集的数据进行了横断面分析。在该研究中，我们旨在调查食物环境与两种社会身份指标（主观社会经济地位（SES）阶梯测量和多元族裔身份测量（MEIM）评分）之间的相互作用，与 n=512 名居住在波士顿和纽约的孕妇的膳食抗氧化剂摄入量（DAI）之间的关系。

方法

使用疾病控制与预防中心的方程计算改良零售食品环境指数（mRFEI），得分越高表示食品环境越健康。DAI 通过对怀孕期间通过 Block98 食物频率问卷获得的六种微量营养素（镁、硒、锌和维生素 A、C、E）的标准化数据进行求和来估计，得分越高表示摄入量增加。mRFEI 和 DAI 根据中位数分为两类。使用多变量调整的逻辑回归分析来分析关联，包括考虑和不考虑女性的主观 SES 或 MEIM 水平作为效应修饰剂的情况。

结果

女性种族/民族混杂（19.2%为白人，42.7%为黑人，33.1%为西班牙裔），其中 32.2%的人受过高中以上教育。在主要效应模型中，mRFEI 与 DAI 之间没有观察到显著关联。MEIM 得分较高的女性表现出较高的 DAI[比值比（OR）=1.85，95%置信区间（CI）=1.26-2.73]。探索性交互模型表明，主观 SES 显著改变了关联（交互作用的 p 值=0.03），具体来说，与社区相比，自我感知 SES 较低的女性（n=45）的 mRFEI 和 DAI 之间存在显著的正相关。
