The purpose of this study was to evaluate the impact of a nutrition intervention on food insecurity among low-income households with children. Data were collected from 371 parent−child dyads in a quasi-experimental evaluation study of a 1-year intervention (n = 6 intervention schools receiving Brighter Bites, n = 6 wait-list control schools), and longitudinal follow-up of the intervention group 2 years post-intervention in Houston, Texas. Data were collected at three timepoints: at baseline and 1 year for all participants, and at 2 year follow-up for the intervention group (the wait-list control group received the intervention during that time). At baseline, most parents reported food insecurity (60.6%; 70% intervention group, 53.6% control). Food insecurity decreased significantly from 81.3% to 61.7% [(−0.32, −0.07) p = 0.002] among intervention participants immediately post-intervention. After adjusting for ethnicity, 2 years post-intervention the predicted percentage of participants reporting food insecurity decreased significantly by roughly 35.4% from 76.4% at baseline to 41.0% [(−0.49, −0.22), p < 0.001]. Between-group changes were not significant. The re-sults of this study demonstrated a significant positive impact of Brighter Bites on food security in the short and long-term among low-income households with children, albeit results should be in-terpreted with caution.
本研究的目的是评估营养干预对有孩子的低收入家庭粮食不安全状况的影响。在一项为期1年干预措施的准实验评估研究中,从371对亲子二元组收集了数据(n = 6所接受“更光明的一口”干预措施的学校,n = 6所等待名单对照组学校),并在德克萨斯州休斯顿对干预组进行了干预后2年的纵向随访。在三个时间点收集数据:所有参与者在基线和1年时,干预组在干预后2年进行随访(等待名单对照组在此期间接受干预)。在基线时,大多数家长报告存在粮食不安全状况(60.6%;干预组为70%,对照组为53.6%)。干预参与者在干预后立即出现粮食不安全状况的比例从81.3%显著下降至61.7% [(-0.32,-0.07),p = 0.002]。在调整种族因素后,干预后2年报告粮食不安全状况的参与者预测百分比从基线时的76.4%显著下降约35.4%至41.0% [(-0.49,-0.22),p < 0.001]。组间变化不显著。本研究结果表明,“更光明的一口”对有孩子的低收入家庭的粮食安全在短期和长期都有显著的积极影响,尽管结果应谨慎解读。
