Prevalence and predictors of microalbuminuria in patients with type 2 diabetes mellitus: A cross-sectional observational study in Oman

Abstract Aim To evaluate the prevalence and predictors of microalbuminuria in type 2 diabetics in Oman. Methods All patients attending an outpatient diabetic clinic at the Sultan Qaboos University Hospital between 2002 and 2003 were enrolled in the study. Results A total of 261 patients were included in this study. The mean overall age of the cohort was 50 ± 13 years, and 57% were male. The proportion of subjects who had microalbuminuria was 27% ( n  = 70; N  = 261). The logistic regression model indicated that significant predictors for the development of microalbuminuria include HbA 1c , log creatinine, and the presence of hypertension. A one unit increase in HbA 1c was associated with a 23% increase in the odds of developing microalbuminuria (OR 1.23; 95% CI: 1.10–1.37; p p  = 0.002). Furthermore, patients who were hypertensive were 2.37 times more likely to have microalbuminuria (OR 2.37; 95% CI: 1.11–5.09; p  = 0.026). Conclusions The prevalence of microalbuminuria in patients with type 2 diabetes in this study was 27%. Significant predictors of microalbuminuria included HbA 1c , creatinine, and the presence of hypertension.
