Background: Coronary artery disease (CAD) is leading cause of mortality in the present era. Obesity is a risk factor associated with CAD. Several clinical tools like body weight, Body mass index, waist circumference, hip circumference, waist-hip ratio, waist-height ratio and skin-fold thickness have been used to define obesity. Higher abdominal fat or visceral fat have been noted to have a strong association with health outcomes due to CAD.
Aim of study: The present study was taken up with an aim to evaluate waist hip ratio as a risk factor for CAD
Material & Methods: The study was conducted in a tertiary care hospital after the approval from the Institutional Ethical Committee. Informed written consent was taken from 50 premenopausal women with age ranging20-50 years. A detailed history was taken and anthropometric measurements: height, weight, waist circumference, hip circumference, waist-hip ratio, waist to height ratio using standard protocols. The study participants were divided according to waist-hip ratio into two groups: Gyanoid: waist-hip ratio between 0.68- 0.8; Android: waist-hip ratio>0.8. Fasting blood sample was taken for lipid profile estimation. Data obtained was subjected to statistical analysis.
Results: The waist-hip ratio was 0.96+/-0.03 in android group and 0.82+/-0.08 in gyanoid group. Statistically significant higher values were observed in total cholesterol, triglycerides and low density lipoproteins in android obesity group.
Conclusion: The study showed that waist hip ratio is a good predictor of central obesity. Android pattern of obesity showed altered lipid profile which makes them more prone for CAD.
