[Objective]To obtain and evaluate the food intake status of primary school students before and after milk intervention,and to provide scientific basis for improving the nutritional and health status of school-age children.[Method]Stratified random sampling method was used to select one urban survey point and one rural survey point from one province in the east,central,and west,with a total of six survey points.Primary school students from grades three to five were selected as the research subjects,with students from school which promoted student milk as the intervention group and school students from school which did not promote student milk as the control group.After the baseline survey,the intervention group students were given a dietary intervention mainly consisting of prepackaged pure milk and nutrition and health education.The intervention period was one year,and nutrition and health education was also provided to the parents of the students.[Result]The difference between the intervention group and the control group students before and after intervention in eight types of food:grains,nuts,vegetables,fruits,livestock and poultry meat,snacks,liquid milk,and milk drinks was statistically significant.The difference between the intervention group and the control group for urban children before and after intervention in five types of food:nuts,vegetables,fruits,snacks,and milk drinks was statistically significant.The difference between the intervention group and the control group for rural children before and after intervention in grains,vegetables,fruits,livestock and poultry meat,liquid milk,sug-ary drinks was statistically significant.[Conclusion]Nutrition education and dietary intervention can effectively improve the milk and dietary intake of primary school students.
