Obesity is a growing problem even in developing regions like India. Obese people are also at risk for social discrimination and possibly adverse psychological consequences.
to study dynamic lung functions and flow rates Forced Expiratory Volume (FEV), Forced Ventilatory Capacity (FVC), FEV1/FVC ratio on subjects and controls.
The study was conducted in the Department of Physiology, SDM College of medical sciences and hospital, Dharwad. 150 male students in the age group 15–24 years of the college formed the subjects of the study.
The mean (±SD) body mass index in overweight group was 23.94 ± 0.55kg/m2, in obese group was 26.81 ± 1.45kg/m2 and in controls was 21.04 1.26 kg/m2. The mean (±SD) age in overweight group was 20.44 ± 1.83 years, in obese group was 20.60 ± 1.78 years and in controls was 19.90 ± 1.31years. The mean (± SD) forced vital capacity at rest in overweight group was 3.54 ± 0.37 litres, in obese group was 3.53 ±
0.76 litres and in controls was 3.82 ± 0.46 litres. The mean (± SD) FEV1 at rest in overweight group was 3.11 ±
0.40 litres, in obese group was 3.10 ± 0.73 litres and in controls was 3.43 ± 0.5 litres. The mean (± SD) FEV1/FVC at rest in overweight group was 0.87 ± 0.37%, in obese group was 0.87 ± 0.03% and in controls was 0.89 ± 0.06%.
FEV1 and FVC were significantly lower in overweight and obese groups compared to controls. FEV1 was reduced more significantly than FVC. But there is no significant change in FEV1/FVC ratio in overweight and obese groups.
