Women with low household income and from racial/ethnic minority groups are at elevated risk of food insecurity. Food insecurity during pregnancy is associated with overall less healthy diets, lower intake of the pregnancy-supportive nutrients iron and folate, and significant variations in diet across the course of a month. The goal of this study was to explore the impact of an ongoing $40/month supplement for fruits and vegetables (F&Vs) provided to pregnant people enrolled in the Special Supplemental Nutrition Program for Women and Children (WIC). Our primary outcome was food insecurity using the USDA 6-item survey, and our secondary outcome was dietary intake of F&Vs based on the 10-item Dietary Screener Questionnaire. Participants in intervention and comparison counties completed surveys at enrollment and approximately three months later (n = 609). Mean ± SD food insecurity at baseline was 3.67 ± 2.79 and 3.47 ± 2.73 in the intervention and comparison groups, respectively, and the adjusted between-group change from baseline to follow-up in food insecurity was 0.05 [95% CI: −0.35, 0.44] (p > 0.05). F&V intake (in cup equivalents) was 2.56 ± 0.95 and 2.51 ± 0.89 at baseline in the two groups, and the adjusted mean between-group difference in changes from baseline was −0.06 [−0.23, 0.11] (p > 0.05). Recruitment and data collection for this study coincided with the most intensive of America’s COVID relief efforts. Our results may indicate that small increases in highly targeted food resources make less of a difference in the context of larger, more general resources being provided to individuals and households in need.
低收入家庭和少数族裔群体的女性面临更高的粮食不安全风险。怀孕期间的粮食不安全与整体更不健康的饮食有关,摄入的铁和叶酸等妊娠支持性营养素较少,而且在一个月的过程中饮食有很大的变化。本研究的目的是探讨向参加妇女和儿童特别补充营养计划(WIC)的孕妇提供每月 40 美元的水果和蔬菜(F&V)补充剂的持续影响。我们的主要结果是使用美国农业部的 6 项调查评估粮食不安全状况,我们的次要结果是根据 10 项饮食筛查问卷评估 F&V 的饮食摄入量。干预和比较县的参与者在入组时和大约三个月后完成了调查(n = 609)。基线时,干预组和对照组的平均 ± SD 粮食不安全程度分别为 3.67 ± 2.79 和 3.47 ± 2.73,从基线到随访的粮食不安全状况调整后的组间变化为 0.05 [95% CI:−0.35, 0.44](p > 0.05)。两组的 F&V 摄入量(杯当量)分别为 2.56 ± 0.95 和 2.51 ± 0.89,从基线到变化的调整后平均组间差异为−0.06 [−0.23, 0.11](p > 0.05)。本研究的招募和数据收集恰逢美国最密集的 COVID 救济工作。我们的结果可能表明,在向有需要的个人和家庭提供更大、更普遍的资源的背景下,针对特定人群的少量增加粮食资源的效果较小。
