To examine the moderation effect of Supplemental Nutrition Assistance Program (SNAP) participation on the baseline fruit and vegetable (FV) intake of Hispanic/Latino and African American children and parents participating in the Brighter Bites program.
Cross-sectional.
Houston, Austin, and Dallas, TX; Washington, DC; and Southwest Florida.
Self-reported surveys (n = 6,037) of Hispanic/Latino and African American adult-child dyads enrolled in Brighter Bites in Fall 2018.
Dependent variable, child FV intake; Independent variable, parent FV intake, and FV shopping behavior; Effect Measure Modifier, SNAP participation.
Quantitatively used mixed effects linear regression models to test if the effect of parental baseline FV intake and shopping behavior on a child's baseline FV intake differed by SNAP participation. Analyses were performed using STATA with significance set at P < 0.05 and 95% confidence intervals (CIs).
For parents that consumed FV ≥ 2 times/d at baseline, there was a 0.1 times increase in child FV intake at baseline among those who participated in SNAP as compared with those who did not participate in SNAP (ß = 0.1; 95% CI, 0.1-0.2; P = 0.001), and for parents who shopped at convenience stores ≥ 2 times/wk for FV, there was 0.6 times increase in child FV intake at baseline for those who participated in SNAP as compared with those that did not participate in SNAP (ß = 0.6; 95% CI, 0.3-0.9; P < 0.001).
Supplemental Nutrition Assistance Program participation moderated the associations between FV intake among African American and Hispanic/Latino parents and children and FV shopping at convenience stores and child FV intake. Findings indicate a need for future interventions to promote SNAP participation among those eligible and improve access to FV.
研究补充营养援助计划（SNAP）的参与情况对参加“更健康饮食”计划的西班牙裔/拉丁裔和非裔美国儿童及其父母的基线水果和蔬菜（FV）摄入量的调节作用。
横断面研究。
得克萨斯州的休斯顿、奥斯汀和达拉斯；华盛顿特区；以及佛罗里达州西南部。
对2018年秋季参加“更健康饮食”计划的西班牙裔/拉丁裔和非裔美国成年子女二元组进行自我报告调查（n = 6,037）。
因变量，儿童FV摄入量；自变量，父母FV摄入量和FV购物行为；效应测量修饰因素，SNAP参与情况。
定量使用混合效应线性回归模型，以检验父母基线FV摄入量和购物行为对儿童基线FV摄入量的影响是否因SNAP参与情况而异。使用STATA进行分析，显著性设定为P < 0.05，95%置信区间（CI）。
对于基线时FV摄入量≥2次/天的父母，参加SNAP的儿童基线FV摄入量比未参加SNAP的儿童增加了0.1倍（β = 0.1；95% CI，0.1 - 0.2；P = 0.001）；对于每周在便利店购买FV≥2次的父母，参加SNAP的儿童基线FV摄入量比未参加SNAP的儿童增加了0.6倍（β = 0.6；95% CI，0.3 - 0.9；P < 0.001）。
补充营养援助计划的参与调节了非裔美国人和西班牙裔/拉丁裔父母及其子女的FV摄入量与在便利店购买FV和儿童FV摄入量之间的关联。研究结果表明，未来需要进行干预，以促进符合条件者参与SNAP，并改善获取FV的机会。
