Correlation Analysis of Body Composition and Lung Function in University Smokers in Their 20s Based on Obesity

Purpose: This study aimed to determine the relationship between college students in their 20s by analyzing the correlation between body composition and lung function according to the presence or absence of obesity in smokers. Methods: A total of 48 participants were enrolled. The body composition of all participants was measured using an Inbody 720. Those with a body mass index of ≥25 kg/m² were classified as the obese smoking group, and those with a body mass index of <25 kg/m² were classified as the general smoking group. After measuring the body composition, lung function was measured using Pony FX. Spearman correlation analysis between each measurement item of body composition and lung function was performed. Results: The body mass index, percent body fat, and visceral fat area of the obese smoking group were significantly negatively correlated with the forced vital capacity (FVC) and forced expiratory volume in 1 s (FEV1), whereas the waist-to-hip ratio, although not significant, showed a negative correlation with FVC and FEV1. However, no correlation was noted among body mass index, percent body fat, visceral fat area, waist-to-hip ratio, and lung functions such as FVC and FEV1 in the general smoking group. Conclusion: The comprehensive analysis revealed that the obese and smoking population exhibited reduced lung function parameters, such as FVC and FEV1, compared with the general smoking population.
