Abstract

Obesity is a pathological condition which increases the risk for cardiovascular disease. The present study was designed to evaluate homocysteine, lipoprotein (a) [Lp(a)], apolipoprotein-B (apo-B), apolipoprotein-A-I (apo-A-I) and lipid indices and their association if any in obese South Indian men. Thirty obese men and thirty age-matched males with normal body weight (controls) were recruited in the study. Plasma homocysteine, Lp(a), lipid profile, apo-A-I and apo-B were estimated in all the subjects. Lipid indices such as lipid pentad index (LPI), lipid tetrad index (LTI), atherogenic index of plasma (AIP), non-high density lipoprotein (non-HDL)/high density lipoprotein (HDL) ratio and apo-B/apo-A-I ratio were calculated in all study subjects. Homocysteine, Lp(a), apo-B, apo-B/apo-A-I ratio and lipid indices were significantly increased in obese men, compared to controls. Both homocysteine and Lp(a) were positively correlated with BMI, waist, hip circumference and apo-B and negatively correlated with apo-A-I. Also we found highly significant positive correlation between homocysteine and Lp(a) levels. The data from the present study concludes that non-conventional risk factors like homocysteine, Lp (a), apo-B/apo-A-I ratio, LTI, LPI, non-HDL/HDL ratio and AIP were significantly elevated in obese Indian men, suggesting they are more prone to develop cardiovascular disease, than the age-matched men with normal body weight.
