Abstract: Objective To explore the influence of school-age children's nutrition and exercise quality on their physical development. Methods A total of 4 032 primary school students were selected into this study by random stratified sampling method in September 2020. Their height, body quality, exercise quality (50m running time, grip strength, standing long jump, stereo forward flexion) were measured, and nutrition intake was assessed, the detection rates of obesity, overweight and malnutrition were analyzed in different nutrition level and sports quality. Results The detection rates of overweight, obesity and low body weight were 12.28%, 7.74%, and 9.42%, respectively, which were 13.01%, 8.50% and 9.47% in boys and 11.51%, 6.95% and 9.38% in girls. Among all the students, the detection rates of overweight and obesity among students with outstanding exercise quality were significantly lower than those in students with poor exercise quality (χ2=216.790, 219.578, 107.187, 102.776, P<0.05). There was no significant difference in the detection rate of malnutrition between students with excellent exercise quality and poor exercise quality (P>0.05). Among all the students, compared with the detection rates of overweight and obesity in students with overnutrition were significantly higher than those in students with inadequate nutrition and balanced nutrition (χ2=727.945, 918.773, P<0.05). The detection rate of low body weight in students with malnutrition was significantly lower than that in students with overnutrition and balanced nutrition (χ2=869.875, 933.032, P<0.05). Conclusion Adequate nutrition intake and high exercise quality can reduce the occurrence of obesity, overweight and malnutrition in school-age children, and maintaining a balanced nutrition and persistent exercise can have a positive significance to the physical development and health of school-age children.
