We use the county-by-county rollout of the program and employ the difference-in-difference (DID) methodology to identify the effects of the implementation of the nutrition improvement program for rural compulsory education students on adolescent health. The results show that the nutrition improvement program reduces the frequency and probability of illness and improves the students' health status. The heterogeneity analysis indicates that the children in western regions and children left behind have a greater marginal improvement. It finds that the nutrition improvement program for rural compulsory education students improves adolescent health through diversifying nutrition intake to alleviate malnutrition and developmental delay in impoverished areas. The program can promote adolescent health in impoverished areas, which has a role in improving regional health disparities and alleviating the intergenerational entrenchment of poverty.
我们利用该计划在各县的推出情况,并采用双重差分(DID)方法来确定农村义务教育学生营养改善计划的实施对青少年健康的影响。结果表明,营养改善计划降低了患病的频率和概率,改善了学生的健康状况。异质性分析表明,西部地区的儿童和留守儿童的边际改善程度更大。研究发现,农村义务教育学生营养改善计划通过多样化营养摄入来改善贫困地区的营养不良和发育迟缓,从而改善青少年健康。该计划可以促进贫困地区青少年的健康,有助于缩小地区健康差距,缓解贫困的代际固化。
