Abstract：Objective To understand the improvement status of food and nutrient supplies in school canteens in the pilot areas after 7 years of implementation of the Nutrition Improvement Program for Rural Compulsory Education Students (NIPRCES) in Inner Mongolia Autonomous Region from 2012 to 2019, and to provide a basis for better implementation of the NIPRCES and formulation of nutrition intervention strategies. Methods According to the principle of random sampling, 20% of schools (including primary and junior middle schools) in each county of the eight pilot counties of the NIPRCES were randomly selected to investigate the food supplies in school canteens and students’ eating conditions in the 2012 and 2019 school years by bookkeeping method. The composition of students in different years was compared by chi-square test, and the food and nutrient supplies in different years were compared by Wilcoxon rank sum test. Results The proportions of low supplies of vegetables, poultry and vegetable oil in the school canteen decreased from 56.82%, 72.73% and 68.18% in 2012 to 29.41%, 32.35% and 20.59% in 2019, while the proportions of excessive supplies of above-mentioned food increased from 25.00%, 6.82% and 20.45% to 55.88%, 44.12% and 50.00%, showing statistically significant differences (all P<0.05). Changes in the supplies of other kinds of food were not significant (P>0.05). The proportions of low supplies of energy, protein, vitamin A, vitamin C and iron significantly decreased from 36.36%, 18.18%, 56.82%, 45.45% and 29.55% in 2012 to 8.82%, 8.82%, 26.47%, 26.47% and 8.82% in 2019, while the proportions of excessive supplies of above-mentioned elements significantly increased from 45.45%, 59.09%, 31.82%, 43.18% and 52.27% to 79.41%, 88.24%, 64.71%, 73.53% and 82.35%, showing statistically significant differences (all P<0.05). The proportions of schools withlow supplies of soy products, eggs and milk in canteens in 2019 were 94.12%, 52.94% and 50.00% respectively, and more than half of the school canteens had excessive supplies of salt. Conclusion After implementing the NIPRCES in Inner Mongolia Autonomous Region in 2012-2019, the situation of food supplies in school canteens in the pilot areas were significantly improved. But there are still unreasonable problems, which need to be further improved.
