摘要

我们研究了在英格兰，营养免费校餐从家庭经济情况调查转为普遍提供对儿童体重的影响。我们根据护士收集的公立学校儿童的全人口健康数据，利用在地方当局之间推广普及供应的机会，估算了不同年龄段和接触持续时间的影响。普及免费午餐降低了 4-5 岁和 10-11 岁儿童的肥胖发生率和体重指数，但年龄较大儿童的体重指数低于年龄较小儿童。我们发现有初步证据表明，影响可能是累积性的，因为对那些在整个小学阶段都接触过全民免费午餐的儿童影响最大。

Universal free school meals and children's bodyweight. Impacts by age and duration of exposure.

We study the impact on children's bodyweight of switching from means-tested to universal provision of nutritious free school meals in England. We exploit the roll-out of universal provision across Local Authorities to estimate effects at different ages and durations of exposure, based on nurse-collected, population-wide health data for state school children. Exposure to universal free lunches reduces obesity prevalence and BMI among children aged 4-5 and 10-11, but older children's bodyweights are less responsive than younger children's. We find tentative evidence that effects may be cumulative, as impacts are largest for those exposed to universal free school meals throughout primary school.
