Correlation of waist-to-hip ratio with smoking and hypertension in coronary artery disease patients: Report from a tertiary care hospital in Bihar

ABSTRACT

Background: Obesity, especially central obesity has been proved to be a risk factor for overall deterioration of health with emphasis on cardiovascular disease. Aim and Objectives: In this study, we aimed to find if there is any correlation between waist-to-hip ratios with smoking and hypertension in patients from a tertiary care hospital in Bihar. Materials and Methods: After taking permission from the institutional ethics committee, this study was conducted in the department of physiology and medicine in a tertiary care hospital in Bihar. Coronary artery disease patients were recruited from the in-patient department of medicine department. The waist circumference and hip circumference were measured by fiberglass measuring tape to the nearest 1 cm. The smoking history and history of hypertension were obtained. Results: A total of 75 patients (57 male and 18 female) were included in the study. There was 26 (34.67%) smoker and 49 (65.33%) non-smoker. Among the patients 34 (45.33%) were suffering from hypertension and 41 (54.67%) patients did not suffer from hypertension (?2 = 0.15, z = 0.38, P = 0.70). There was no gender difference in waist-to-hip ratio (WHR) (t = 0.4553, P = 0.65). Among the patients, WHR, smoking, and hypertension did not show any significant correlation. Conclusion: Among the coronary patients, there was no correlation of WHR with smoking and hypertension. Even smoking and hypertension did not show any relationship. Hence, obesity, smoking, and hypertension should be considered as individual risk factors for coronary artery disease.
