ABSTRACT

Background: Obesity increases the risk of developing many co-morbidities like dyslipidemia, atherosclerosis, CHD, hypertension, insulin resistance which may lead to metabolic syndrome. There is alarming rise of obesity in present era. Obesity being a modifiable risk factor for metabolic syndrome can be kept in check by restricted diet and physical activity, which can prevent the diseases, such as CHD, hypertension etc. This study was done with an aim to estimate the serum lipid profile levels in obese subjects with BMI ≥ 30 kg/m2 and to compare them with that in non–obese subjects with BMI 18.5 - 24.9 kg/m2. Methods: In this cross-sectional study, the records of 100 patients who have visited cardiac OPD for evaluation were included for the study and the following parameters were examined: age, sex, body mass index, and lipid profile. Results: A total of 100 (50 obese and 50 non-obese) subjects were analyzed in this study. Elevated levels of TC, TGL and LDL were found in obese individuals when compared to non- obese individuals. However, no significance was noted with VLDL. In male and female subjects, elevated levels of TC, TGL and LDL were noted as compared to their respective non-obese subjects. Significantly elevated levels of TC and HDL were found in obese women compared to obese men, however no significant change was observed related to LDL though elevated levels were noted. Conclusion: Serum lipid profile parameters (except HDL) are raised in obese compared to non obese counterparts. The raised lipid profile parameters enhance the risk of developing atherosclerosis and CHD.
