Objective: There are studies regarding pulmonary functions of obese individuals in literature; however, there is insufficient data regarding pre-obese individuals. This study aimed to compare the pulmonary functions, physical activity levels, and health-related quality of life (HRQOL) of obese and pre-obese individuals.

Methods: The characteristics of 62 subjects participating in the study were recorded All subjects were evaluated using pulmonary function tests (PFT), short form-36 health survey (SF-36), obesity and weight loss quality of life measure (OWLQOL), international physical activity questionnaires (IPAQ), and modified medical research council (mMRC) scale.

Results: The severity of perceived dyspnea in obese subjects was significantly higher than that in pre-obese subjects. The PFT parameters (FVC, FEV1, PEF, FEF25–75, FEF25–75%, MVV, and MVV%) were significantly lower in obese subjects. Although individuals in both groups were inactive, the inactivity levels in obese subjects were significantly higher. HRQOL scores were significantly lower in obese individuals. The body mass index (BMI) was significantly correlated with dyspnea severity, SF-36 subscores, OWLQOL scores, and PFT parameters.

Conclusion: While an increasing BMI has an adverse effect on the pulmonary functions of pre-obese individuals, increased BMI coupled with reduced pulmonary functions causes a decrease in the physical activity levels and reduces HRQOL of obese individuals.

Keywords: Lung function, obesity, physical activity, pulmonary function test, quality of life
