Good nutritional status in childhood serves as the foundation for lifelong health.Malnutrition during childhood can not only impede children’s growth and development,but also lead to a higher incidence of chronic diseases in adulthood,thereby increasing the socioeconomic burden.In order to improve the nutritional and health status of children living in economically underdeveloped rural areas,the Chinese government implemented the Nutrition Improvement Program for Rural Compulsory Education Students(NIPRCES)in November 2011(1).The central government provides nutritional meal subsidies to rural compulsory education students in underdeveloped counties.Initially,NIPRCES covered rural area of 699 national pilot counties across 22 provincial-level administrative divisions(PLADs)in the central and western regions of China.By 2021,the program expanded to encompass 727 national pilot counties and 1,010 local pilot counties spanning 28 provinces in the eastern,central,and western regions of China,serving more than 36 million students.
