Methods: In Zhalaiteqi County students’ physical health survey data and learning achievement scores from 2012 to 2013 were selected as research data, and the nutritional status of the students was judged by statistical analysis of physical data. Results: The malnutrition rate was 22.21%, the overweight rate was 6.0%, and the obesity rate was 3.81% in 2012. The detection rate of the male normal group was 80.22%, and the detection rate of the female normal group was 75.63%. The difference was statistically significant (χ2 = 27.036 P Conclusion: The nutritional status of students in poverty-stricken areas in Inner Mongolia cannot be neglected. Weight loss and obesity have a negative impact on students’ academic performance. Effective measures should be taken to control the present situation.展开更多
