Obesity has been reported to develop lung problems and causes a significant medical health problem for the future of student’s health.

This study aims to determine whether there is a relationship between lung capacity volumes values and BMI levels, height, weight among students aged 7–22 years old.

Material and methods:
This is a cross-sectional study among 255 581 students aged 7–22 years-old. Electronic spirometer device was used for diagnose of lung conditions, and ultrasonic scale machine (SY133) was used to measures body weight and height. BMI was calculated based on Chines Working Group on Obesity in China (WGOC) standard.

Results and discussion:
Mean of lung capacity volume (mL), and the ratio of vital lung capacity and BMI (mL/kg) in males were significantly more than females (P < 0.001), also the differences in lung volumes by gender was reported within the 13 cities in Jiangsu Province. Lung capacity (mL) was showed significant positive association with height (r = 0.70, P < 0.001), weight (r = 0.60, P < 0.001) in males and body height in females (r = 0.54, P < 0.001), respectively. The significantly low, moderate positive association was reported in males lung capacity volume (P < 0.001) compare with the negative association in females within the ratio of vital lung capacity and BMI (P < 0.001). BMI, as reported, lowers association values of lung volume.

We found that age gender has significant effects on lung capacity volumes, and obese students were noticed lower lung volumes. Therefore, comprehensive intervention measures dominant by physical exercise should be adopted towards student’s health.

This work was founded by the Jiangsu Provincial Social Science Foundation Grant No. 3TYA001 and Key Laboratory of Environmental Medicine and Engineering School of Public Health, Southeast University. And we are grateful to participant and outstanding professional health staff in Jiangsu Provisional Center for Disease Control and Prevention, for their kind cooperation and assistance in this study.
