摘要

背景食品环境是造成营养不良双重负担的驱动因素，它通过增加或限制获得食品的机会来影响膳食摄入量。目标本研究旨在评估孟加拉国农村地区产后妇女的地理空间食品环境指标与膳食质量之间的关联。食品摊贩可用性定义为特定家庭半径内的食品摊贩数量，邻近性定义为与最近摊贩的距离。膳食摄入量通过产后 3 个月、6 个月和 12 个月收集的 7 天食物频率问卷进行测量。我们的主要结果是非淀粉类主食多样性得分（FVS）。次要结果包括膳食多样性得分和单个食物组的消耗量。为了评估食物环境指标与饮食质量指标之间的关联，我们对 FVS 结果拟合了线性回归模型，对饮食多样性结果拟合了泊松回归模型，对个别食物组结果拟合了逻辑回归模型。据报告，妇女在前一周平均食用了 9.7 种（标准差：3.7）非淀粉类主食。与市场供应量最低（≤ 2 个市场）的家庭相比，生活在市场供应量最高（1600 米内≥ 7 个市场）的家庭中的妇女的食物摄入量平均高出 0.84 单位（95% 置信区间：0.53，1.16）（P < 0.001）。结论我们发现，孟加拉国农村地区产后妇女的市场供应与饮食质量之间存在正相关关系。然而，还需要进行更多的研究，以了解食品环境的哪些因素与摄入较不健康食品的增加有关。

The Association Between an Individual’s Local Food Environment and Diet Quality among Postpartum Women Living in Rural Bangladesh

Background

The food environment is a driver of the double burden of malnutrition, influencing dietary intake by increasing or restricting access to foods.

Objectives

The objective of this study was to assess the association between geospatial food environment indicators and the diet quality among postpartum women in rural Bangladesh.

Methods

Participants were women of infants enrolled in a cluster-randomized controlled trial from 2018 to 2020. Food vendor availability was defined as the number of food vendors within a specific household radius, and proximity was defined as the distance to the nearest vendor. Dietary intake was measured using a 7-d food frequency questionnaire collected at 3 mo, 6 mo, and 12 mo postpartum. Our primary outcome was nonstarchy staple food variety scores (FVS). Secondary outcomes included dietary diversity scores and individual food group consumption. To assess the association between food environment indicators and diet quality indicators, we fit linear regression models for the FVS outcome, Poisson regression models for the dietary diversity outcome, and logistic regression models for individual food group outcomes.

Results

A total of 5064 women were included in this analysis. Women reported consuming an average of 9.7 (standard deviation: 3.7) nonstarchy staple foods in the previous week. Women who lived in households with the highest market availability (≥7 markets within 1600 m) had an average of 0.84-unit (95% confidence interval: 0.53, 1.16) higher FVS compared with those in households with the lowest market availability (≤ 2 markets) (P < 0.001). Geospatial food environment indicators were not significantly associated with the odds of consuming less healthy food options.

Conclusions

We found a positive relationship between market availability and diet quality for postpartum women in rural Bangladesh. However, more research is needed to understand which components of the food environment are associated with increased consumption of less healthy foods.
