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

AimTo evaluate the prevalence and predictors of microalbuminuria in type 2 diabetics in Oman.MethodsAll patients attending an outpatient diabetic clinic at the Sultan Qaboos University Hospital between 2002 and 2003 were enrolled in the study.ResultsA 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 HbA1c, log creatinine, and the presence of hypertension. A one unit increase in HbA1c was associated with a 23% increase in the odds of developing microalbuminuria (OR 1.23; 95% CI: 1.10–1.37; p < 0.001). Additionally, patients that had a one unit increase in log creatinine were 5.72 times more likely to develop microalbuminuria (OR 5.72; 95% CI: 1.86–17.59; 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).ConclusionsThe prevalence of microalbuminuria in patients with type 2 diabetes in this study was 27%. Significant predictors of microalbuminuria included HbA1c, creatinine, and the presence of hypertension.
