Abstract

Background: Fat-free mass (FFM) and fat mass (FM) are not necessarily similar in individuals within normal range of body mass index. Fat-free mass index (FFMI) and fat mass index (FMI) affect the dynamic lung functions in young Indians.
Objective: To check the relation of body composition with lung function in young Gujarati Indian population and learn if any gender difference exists in such relation.
Materials and Methods: A cross-sectional study was conducted on 102 male and 84 female subjects in the age group of 17–21 years. Body composition parameters such as FFM, FM, and total body fat% were measured by Omron HBF-302, a body fat monitor. Dynamic lung functions [forced expiratory volume in 1 s (FEV ), forced expiratory volume at 6 s (FEV ), 1 6 , FEV /FEV and peak expiratory flow rate (PEFR)] were recorded using PiKo-6 and Wright’s peak flow meters. 1 6 , Result: FEV , FEV and PEFR were significantly lower in female subjects when compared with male subjects. FMI 1 6 showed a significant negative correlation with dynamic lung functions, while FFMI showed a significant positive correlation with dynamic lung functions. Body composition parameters such as FM and FFM (lean body mass) were associated with the dynamic lung functions in young Gujarati Indian students. Conclusion: We may conclude that FFM and FM are significantly associated with the dynamic lung functions in young Gujarati Indian students in the age group of 17–21 years. FFM shows a positive correlation with lung functions, and FM shows a negative correlation with lung functions.
