ASSOCIATION OF SLEEP TIME WITH DIABETES MELLITUS AND IMPAIRED GLUCOSE TOLERANCE

Abstract

Introduction: In the present study, we was examined the relation of self-reported usual sleep time to prevalence DM and IGT in a large hospital based sample of middle-aged and older adults. Methods: Cross-sectional study was conducted on 625 patients between age group 18-60 yrs and both sex. Usual sleep time was obtained by standardized questionnaire. Diabetes mellitus was defined as a serum glucose level of 126 mg/dL or more fasting or 200 mg/dL or more 2 hours following standard oral glucose challenge or medication use for DM. Impaired glucose tolerance was defined as a 2-hour post challenge glucose level of 140 mg/dL or more and less than 200 mg/dL. The relation of sleep time to DM and IGT was examined using categorical logistic regression. Results: 49.28% subjects sugar level was more than 200 mg/dl and 13.72% subjects sugar level less than 140 mg/dl. The association between sleeping time and blood sugar level was found statistically significant. The association between Sleeping time and blood sugar level was found statistically significant Conclusion: A sleep duration of 6 hours or less or 9 hours or more is associated with increased prevalence of DM and IGT. Because this effect was present in subjects without insomnia, voluntary sleep restriction may contribute to the large public health burden of DM. Keywords: DM, IGT, Hb1Ac
