Objectives To understand the nutritional status of sixth grade pupils who have just entered adolescence to identify problems and take corresponding measures. Methods The height standard weight method was used to monitor the nutritional status of 531 students in the sixth grade of primary school in Daxing district from 1998 to 2002. Results The malnutrition rate of 5-year students was 11.69% on average, showing a declining trend year by year. The average obesity rate was 17.70%, showing a slight upward trend, but the difference was not statistically significant. The malnutrition rate of girls was higher than that of boys (Χ2 = 13.88, P <0.01). The obesity rate was lower than that of boys, the difference was statistically significant (χ2 = 16.71, P <0.01). Malnutrition was mild (88.16%). Conclusion Nutrition knowledge education should be strengthened to achieve a balanced diet.
