Original InvestigationsRisk factors for microalbuminuria in black americans with newly diagnosed type 2 diabetes
Section snippets
Study population
We studied black patients with type 2 diabetes from an economically disadvantaged urban population with low levels of literacy and poor health insurance coverage.14, 31 Patients with a diabetes diagnosis for 2 years or less who presented to the Grady Diabetes Clinic (Atlanta, GA) for the first time between January 1, 1994, and December 31, 1996, were eligible for inclusion. Patients with both urine albumin and urine creatinine measurements at this visit were included in the analyses; patients
Results
Record review identified 1,167 eligible patients. Adequate information was available to calculate the Alb/Cr ratio for 1,055 of these patients (90.4%). Eleven patients with serum creatinine levels of 2 mg/dL or greater were excluded. Of the remaining 1,044 patients, 40 patients (3.8%) had clinical nephropathy (Alb/Cr >250 μg/mg) at the initial visit, 244 patients (23.4%) had microalbuminuria, and 760 patients (72.8%) had normoalbuminuria (Table 1).
Discussion
The urban black Americans with type 2 diabetes in our study had a high prevalence of microalbuminuria despite short duration (≤2 years) of diagnosed diabetes. Studies of other nonwhite type 2 diabetic populations have also noted a high prevalence of microalbuminuria; however, these studies did not focus solely on those with short diabetes duration.14, 15, 38, 39 Few studies have examined microalbuminuria in black Americans with type 2 diabetes.
Patients with type 2 diabetes are believed to have
