The primary objective of this research project is to determine risk factors related to the development of microalbuminuria. The secondary objective is to determine whether uric acid levels at the final visit are correlated with the onset of microalbuminuria. Of participants returning for a 4-5 year follow up visit as part of a continuing project, we will examine the proportion that have developed microalbuminuria. Subjects found to have microalbuminuria will be offered therapy with the ARB losartan and will be followed at three months to determine if there has been a reduction in levels.
