ABSTRACT Background High rates of iron‐deficiency anemia among school‐age children have been a common issue in developing countries. In 2012, China rolled out a school feeding program (SFP) to address this issue. This study assesses changes in anemia rates, as well as potential factors driving these changes, both 3 and 10 years after the SFP was implemented. Methods Data were from two cross‐sectional surveys ( n = 1510) in northwestern China. T ‐tests were used to compare the differences in health outcomes of students and their dietary diversity across the different sample years. Regressions were used to examine the associations between health outcomes and dietary diversity. Results After the SFP was launched, hemoglobin levels of students improved from 126 to 131 g/L between 2015 and 2022/2023; the rates of anemia and stunting decreased from 17% to 6% and 9% to 1%, respectively. A rise in student dietary diversity and an increase in the share of students that consumed iron‐rich foods are two main contributing factors. Implications for School Health Policy, Practice, and Equity Increase in funding allotted to the SFP over time appears to be a key element in improving the health and nutrition of rural students. Conclusions SFP in rural China exemplifies the concrete advantages in improving the health and potential educational outcomes of students.
