MICROALBUMINURIA AND ITS RISK FACTORS IN PATIENTS WITH TYPE 2 DIABETES

Diabetes is one of the most common metabolic diseases. The prevalence of diabetes, which is around 4.5 - 6% in Iran, reaches as high as 14.2% in population of age 30 years and over in Yazd. Microalbuminuria is diagnosable before development of nephropathy and could be detected at an early stage when effective therapy can still be carried out. In this stage near normalization of blood glucose, strict blood pressure control and administration of ACE inhibitors can prevent nephropathic complications.This study was aimed to determine the correlation among microalbuminuria, age, duration of diabetes, body mass Index, serum triglyceride, serum cholesterol and blood pressure in type 2 diabetic inhabitants of Yazd diabetes research center. This cross-sectional study was carried out during November 2002-July 2003 to investigate the correlation between microalbuminuria and assumed risk factors. Two hundred and eighty eight type 2 diabetic patients (141 males and 147 females) were selected through consecutive sampling. Overall prevalence of microalbuminuria was 14.2%. Chi-square analysis revealed the association between microalbuminuria and high diastolic blood pressure (P-value=0.003) and duration of diabetes (P-value = 0.001). No statistically significant correlation was found between microalbuminuria and body mass index, serum triglyceride, serum cholesterol and systolic blood pressure. Determination of urine albumin/creatinin ratio is an easy method for screening microalbuminuria which is recommended for all diabetics especially those with hypertension and a long term history of diabetes.
