Abstract
The aim of the present study was to investigate the prevalence of fear of hypoglycemia, in association with severe hypoglycemia and social factors, in insulin-treated patients with type 2 diabetes mellitus. A questionnaire survey on hypoglycemia and patient-physician communication was carried out in 355 patients with insulin-treated type 2 diabetes mellitus patients at 16 hospitals and clinics. A fear of hypoglycemia was reported by 27.7% of patients. A stepwise logistic regression analysis found that severe hypoglycemia during the past 1 year was a significant determinant of fear of hypoglycemia (odds ratio 2.16, 95% confidence interval 1.06-4.41; P = 0.034), and age (odds ratio 1.02, 95% confidence interval 1.00-1.05, P = 0.038) and living alone (odds ratio 1.93, 95% confidence interval 1.00-3.73, P < 0.05) were significantly higher in patients with fear of hypoglycemia than in those without it.
