The relationship between obesity and forced vital capacity among university students.

Objective: We sought to explore the relationship between vital capacity and obesity among university students in China.

Methods: A cross-sectional study was designed to collect the routine health screening data for university students in 2013. The height, weight and force vital capacity of students were measured, and BMI was calculated with height and weight, so as to estimate the relationship between force vital capacity and obesity.

Results: Based on Working Group on Obesity references in China, obesity has a higher force vital capacity in both male and female university students. No correlation was found between vital capacity and BMI.

Conclusion: obesity may have effect on pulmonary function among university students, which is a reference for further epidemic study.
