The overall malnutrition rate in the province was 6. 89%. A total of 89 children and adolescents had stunting with a stunting rate of 2. 76%. In addition to stunting, there were 59 moderate-serve wasting(1. 83%) and 74 mild wasting(2. 30%). The malnutrition of rural students was more serious than that of cities. The overweight and obesity rates of children and adolescents in big cities, small and mediumsized cities, ordinary rural areas and poor rural areas were 10. 0%, 9. 69%, 5. 47%, 4. 56%, and 9. 02%, 9. 34%, 3. 40% and 4. 10%, respectively.
