Abstract

A descriptive cross-sectional study was implemented in Nghe An province from September 2010 to March 2020. The goal of the study was to assess nutritional status of
3034 students and anemia and micronutrient deficiency of 300 students in 6 selected
primary schools, which effectively operated the school milk program to evaluate the
efficacy of that program after 3 years of implementation. The results shown that the
rate of undernourished student was low, in which underweight was 7.5%, stunting was
5.9%, overweight and obese classified by BMI for age was 18.1%. The percentage of
underweight in the rural was higher than that in the urban, the rate of underweight in
female students was significantly higher than that of male students (p < 0.05). Whereas,
the rate of obesity in the urban was higher than that in the rural, and the proportion of
overweight and obesity of boys was higher than that of girls. In addition, the percentage of overweight and obesity in students playing game and watching TV more than 2
hours was higher than that of those having less than 2 hours. For the results of anemia
and micronutrient deficiency: the rate of zinc deficiency was accounted for 76.1%,
while vitamin A was 4.3% and anemia was 0.3%. In conclusion, the nutritional status
of student has been significantly improved: the rate of undernourishment was low, the
percentage of overweight and obesity was slightly increased, the proportion of anemia
and vitamin A was very low, however, zinc deficiency was still very high.
