The analysis of risk factors for hypoglycemia in hospitalized patients with type-2 diabetes

Objective: To explore the risk factors for hypoglycemia in hospitalized type-2 diabetic patients,provide the reference for reaching the standard of blood sugar and avoiding hypoglycemia.Methods: A total of 640 type-2 diabetic patients were collected in inpatient department of our hospital from April,2010 to December,2011.There were 132 subjects identified as hypoglycemia and 508 subjects as no hypoglycemia.The clinical data of two groups were compared and logistic regression analysis was performed to reveal the risk factors for hypoglycemia.Results: Longer duration of diabetes,longer hospital days,lower body mass index were more common in patients with hypoglycemia as compared to those without them.With logistic regression analysis,age,endogenous creatinine clearance rate,body mass index,the duration of diabetes and hospital days were independent risk factors of hypoglycemia(P 0.05).Conclusion: In hospitalized type-2 diabetic patients,longer duration of diabetes,longer hospital days,lower body mass index and renal dysfunction increase the hypoglycemia.On the other hand,longer hospital days may make the exposure of hypoglycemia.So clinical practitioners should adopt measure to balance the hyperglycemia therapy and hypoglycemia.
