To test the hypothesis that children in Food FARMacia-a six-month food insecurity intervention from May 2019 to January 2020-would have smaller age-adjusted, sex-specific body mass index (BMIz) gains than matched counterparts.
In this proof-of-concept study, we performed a difference-in-differences (DiD) analysis of a propensity-score matched cohort among paediatric primary care patients aged <6 years with household food insecurity. Children with anthropometric measures prior to and after intervention started were included. The main outcome was child BMIz from standardized clinical anthropometric measurements. We examined differences in child BMIz change between Food FARMacia participants and matched non-participants.
Among 454 children with household food insecurity, 265 were included, 44 of whom were in Food FARMacia. Mean child age was 1.48 (SD 1.46) years and most reported Hispanic/Latino ethnicity (84.5%). After propensity score matching, children in Food FARMacia had smaller increases in BMIz (unadjusted DiD -0.28 [-0.52, -0.04]) compared to non-participants in the follow-up period. After adjusting for potential confounders, findings remained statistically significant [adjusted DiD, -0.31 units (95% CI: -0.54, -0.08)].
In this proof-of-concept cohort study of children in households with food insecurity, a paediatric primary care-based mobile food pantry program was associated with improvement in child BMIz over 6 months.
检验以下假设，即参加 2019 年 5 月至 2020 年 1 月为期 6 个月的食品保障干预计划“食品药房”（Food FARMacia）的儿童的年龄调整后、性别特异性体重指数（BMIz）增长幅度将小于匹配对照组的儿童。
在这项概念验证研究中，我们对儿科初级保健患者中患有家庭食物不安全的 <6 岁的儿童进行了倾向评分匹配队列的差异-差异（DiD）分析。包括在干预开始前和开始后进行了人体测量的儿童。主要结局是儿童标准化临床人体测量学测量的 BMIz。我们检查了“食品药房”参与者与匹配的非参与者之间儿童 BMIz 变化的差异。
在 454 名患有家庭食物不安全的儿童中，纳入了 265 名儿童，其中 44 名儿童参加了“食品药房”。儿童的平均年龄为 1.48 岁（标准差 1.46 岁），大多数报告了西班牙裔/拉丁裔种族（84.5%）。在进行倾向评分匹配后，与非参与者相比，“食品药房”中的儿童在随访期间的 BMIz 增长幅度较小（未调整的 DiD，-0.28 [ -0.52，-0.04]）。在调整潜在混杂因素后，结果仍具有统计学意义[调整后的 DiD，-0.31 单位（95%CI：-0.54，-0.08）]。
在这项针对家庭食物不安全儿童的概念验证队列研究中，基于儿科初级保健的移动食品储藏室计划与儿童 BMIz 在 6 个月内的改善有关。
