Prevalence of diabetes mellitus among obese and non-obese patients with coronary artery disease.

Background: Globally, obesity is now recognised as an epidemic. The degree of obesity is proportional to the rate of development of cardiovascular diseases, hence, resulting in a dramatic increase in morbidity and mortality. Apart from obesity, diabetes mellitus is another well recognised risk factor contributing to coronary artery disease. The precise prevalence of obesity-related diabetes varies with age, race and gender; and is yet unknown in our population. We therefore, carried out this study with the aim to determine the prevalence of diabetes mellitus in obese and non-obese patients with diagnosed coronary artery disease.

Methods: This hospital based cross-sectional comparative study was conducted in Cardiology Department of Postgraduate Medical Institute, Lady Reading Hospital, Peshawar, from 15th March 2005 to 30th May 2006. A total of 200 patients with diagnosed coronary artery disease were enrolled, 100 were classified as obese and 100 as non-obese.

Results: Among these, 139 patients were male and 61 female. A total of 88 were found to be diabetic, 54 of these were obese and 34 non-obese (p = 0.004).

Conclusion: Diabetes mellitus was significantly more frequent among obese patients with coronary artery disease as compared to non obese patients with coronary artery disease.
