Vascular complications in noninsulin dependent diabetes mellitus (NIDDM) in Srinagarind Hospital, Khon Kaen

We prospectively conducted a hospital based study to determine the prevalence of vascular complications in NIDDM and their risk factors. Using standard protocol for interviewing, physical examination and laboratory investigations, we studied 207 patients from the diabetic clinic and medical outpatient department (ratio 3.9:1) by systematic sampling. The prevalence of hypertension, coronary heart disease cerebrovascular disease, peripheral and large vessel disease was 22.2, 22.2, 8.2, 21.3 and 34.8 per cent respectively. We found that the prevalence of small vessel disease, retinopathy and nephropathy was 34.3, 25.1 and 12.5 per cent respectively. The complications were slightly higher in females and increased with duration of diabetes. By univariate and logistic regression analysis, we found that the risk factors of large vessel disease were body mass index, diastolic blood pressure, duration of diabetes and for small vessel disease were duration of diabetes and high uric acid.
