背景资料：包括学校供餐在内的以粮换教（FFE）计划被广泛用于改善学校参与和表现，但有关营养益处的证据有限。目的：本研究测试了FFE计划中提供的多种微量营养素强化食品是否降低了小学适龄少女、成年妇女和学龄前儿童的贫血患病率。通过使用个体水平重复横断面数据的整群随机对照试验，我们测量了2个FFE项目对贫血患病率的影响，学校供餐计划（SFP）提供多种微量营养素强化餐和营养等效的带回家口粮（THR）。在乌干达北方的国内流离失所者（IDP）（n = 31）营地被随机分配到SFP，THR，或没有FFE的对照组。在SFP和THR学校提供了15个月的口粮。对有6-17岁儿童的家庭（n = 627）进行了调查（基线和18个月后）。结果：FFE学校10-13岁的青春期女生贫血患病率显著降低（P < 0.05）25.7个百分点（95%CI：-0.43，-0.08）。
Background: Food for education (FFE) programs that include school meals are widely used to improve school participation and performance, but evidence on nutritional benefits is limited.Objective: This study tested whether food fortified with multiple micronutrients provided in FFE programs reduced anemia prevalence of primary-school-age adolescent girls, adult women, and preschool children.Methods: Through the use of a cluster randomized controlled trial with individual-level repeated cross-sectional data, we measured impacts on anemia prevalence from 2 FFE programs, a school feeding program (SFP) providing multiple-micronutrient-fortified meals and a nutritionally equivalent take-home ration (THR). Camps for internally displaced people (IDP) (n = 31) in Northern Uganda were randomly assigned to SFP, THR, or a control group with no FFE. Rations were provided for 15 mo at SFP and THR schools. A survey of households (n = 627) with children aged 6-17 y was conducted (baseline and 18 mo later). Analyses used difference-in-differences by intent to treat.Results: Adolescent girls aged 10-13 y in FFE schools experienced a significant (P < 0.05) 25.7 percentage point reduction (95% CI: -0.43, -0.08) in prevalence of any anemia [hemoglobin (Hb)
