Overweight or obesity can cause dangerous health problems and impair quality of life. Due to change in life style and lack of physical activity the problem of obesity is increasing by fast rate in 21 st century. Obesity is important risk factor for diabetes, hypertension, atherosclerosis, cancer etc. It also causes disturbances in the respiratory functions. Material and Methods: The study included 100 adult male Medical students, 50 obese and 50 non obese in age group of 18 to 22. We have

Height and weight were measured to find out BMI (Body mass index). WC (waist circumference), HC (Hip circumference) and W/H (waist hip ratio) was measured to see the adiposity. Respiratory muscle strength was assessed by respiratory pressure apparatus manufactured by Vacumed, California, USA. Results: It was observed that the respiratory parameters, mean maximum expiratory pressure (MEP) was 102.48 cmH 2 O (+ 8.21) in obese group and 82.84 cmH 2 O (+ 6.84) in non obese group while mean maximum inspiratory pressure (MIP) was 88.82 cmH 2 O (+ 6.46) in obese group and 68.92 cmH 2 O (+ 5.96) in non obese group. Pearson correlation analysis shown that MEP and MIP of the groups were associated weak positive to moderate positive with WC, HC and W/H ratio, but it was not statistically significant. Conclusion: The alterations in respiratory muscle strength by obesity were evidenced in the parameters MEP and MIP, suggests that obesity affects to the respiratory mechanics. Overload of fat on respiratory muscles and chest region require more pressure during respiration. It may be prevented if active measures are taken to reduce weight by change in lifestyle & food habits.
