妊娠期间特定食物组和/或营养素的膳食摄入与孕妇和婴儿的妊娠相关结局有关。很少有研究探讨了行为和环境因素如何相互作用以影响产前饮食。我们研究了饮食行为（饮食节制、情绪性进食、外部进食）与食品安全状况对妊娠期选择性营养素/食物组织膳食摄入的关联。参与者（N = 299; 29% 非裔美国人; 16% ≤ 高中教育; 21% 食品不安全）通过国家癌症研究所膳食筛查问卷完成了验证问卷，以评估妊娠期间食物组和营养素的预估每日摄入量[例如，糖甜饮料中的添加糖（SSBs），脂肪能量百分比，水果和蔬菜（FV）摄入量]；饮食行为（荷兰饮食行为问卷）；以及食品安全状况（6项美国农业部食品安全模块）。针对每个膳食结果进行了单独的分层多重回归分析，控制了母亲年龄，教育水平，收入需求比，种族/民族，妊娠前BMI和妊娠期糖尿病。发现饮食节制和食品安全状况在从SSBs中摄入添加糖方面存在显著的相互作用（β = -0.15，p = 0.02）。食品不安全参与者间的节制与从SSBs中摄入添加糖的负相关更强（β = -0.47，p < 0.001 vs. β = -0.15，p = 0.03）。更高的外部进食（β = 0.21，p < 0.01）、较低的节制（β = -0.13，p = 0.03）与生活在食品不安全家庭（β = -0.15，p = 0.01）均与能量来自脂肪的百分比更高和蔬果摄入量较低相关。了解妊娠期间的膳食摄入需要考虑饮食行为发生的更广泛背景。版权所有©2023年 Elsevier Ltd.

Dietary intake of certain food groups and/or nutrients during pregnancy has been associated with maternal and infant pregnancy-related outcomes. Few studies have examined how behavioral and environmental factors interact to influence prenatal diet. We examined associations between eating behaviors (dietary restraint, emotional eating, external eating) and food security status regarding dietary intake of selected nutrients/food groups during pregnancy. Participants (N = 299; 29% Non-Hispanic Black; 16% ≤ high school education; 21% food insecure) completed validated questionnaires to assess estimated daily intake of food groups/nutrients during pregnancy [e.g., added sugars from sugar-sweetened beverages (SSBs), % of energy from fat, fruit and vegetable (FV) intake] via National Cancer Institute Dietary Screener Questionnaires); eating behaviors (Dutch Eating Behavior Questionnaire); and food security status (6-item USDA Food security Module). Separate hierarchical multiple regressions for each dietary outcome were conducted controlling for maternal age, education, income-to-needs, race/ethnicity, pre-pregnancy BMI, and gestational diabetes. A significant interaction was found between dietary restraint and food security status on added sugar intake from SSBs (β = -0.15, p = 0.02). The negative association between restraint and added sugar from SSBs was stronger among food insecure participants (β = -0.47, p < 0.001 vs. β = -0.15, p = 0.03). Higher external eating (β = 0.21, p < 0.01) and lower restraint (β = -0.13, p = 0.03) were associated with higher % of energy from fat and living in a food insecure household (β = -0.15, p = 0.01) was associated with lower FV intake. Understanding dietary intake during pregnancy requires consideration of the broader context in which eating behaviors occur.Copyright © 2023. Published by Elsevier Ltd.
