Metabolic control and nocturnal enuresis in children with type 1 diabetes.

This study examined the relationship between metabolic control and enuresis in youths with type 1 diabetes. Participants were 203 youths with type 1 diabetes at an outpatient pediatric diabetes clinic. Outcome measures included HbA(lc), nocturia, blood glucose, polydipsia, frequency of daytime urination, and diabetic ketoacidosis. The mean fasting blood glucose (FBG) level of children with enuresis (FBG = 192 mg/dl) was significantly higher than that of children without enuresis (FBG = 160 mg/dl, p = .03). Differences in HbA(lc) levels between children with enuresis and those without enuresis approached significance (9.2% vs. 8.6%, p = .07). Findings indicate that metabolic control indices (FBG, HbA(1c), polyuria, and polydipsia) are related to nocturnal enuresis in youths with type 1 diabetes. Further studies should determine the mechanism by which this relationship occurs to initiate appropriate interventions.
