Hypertension, glycemic control and microalbuminuria in Haitian Americans and African Americans

Abstract

This cross‐sectional study investigated the relationship between hypertension (HTN), glycemic control (GC) with microalbuminuria (MAU) in African Americans (AA= 129) and Haitian Americans (HA=137) with type 2 diabetes (T2D). Participants were recruited from multiple sources from Miami‐Dade and Broward Counties, FL. Blood pressure (BP) was measured using an adult size cuff. Glycosylated hemoglobin (A1C) levels were measured from fasting blood samples with the Roche Tina‐quant method. MAU was determined in urine samples by a semiquantitative assay (ImmunoDip). Unadjusted odds ratios indicated that participants with poor GC were 2.6 times more likely to have MAU (P=.001; OR = 2.61, 95% CI 1.50, 4.50) compare to those with good GC. Logistic regression showed that participants with poor GC were 2.3 times more likely to have MAU if they had hypertension compared to those without hypertension (P=.004; OR= 2.37, 95% CI 1.32, 4.25). These findings point out the importance of early detection of MAU in both ethnic groups. Adequate blood pressure control along with glycemic control are needed to prevent and treat diabetes complications. Funding for this research was provided through NIH/NIDDK sponsored grant.
