Experimental sleep restriction causes type 2 diabetes mellitus (DM-2); however, little is known about the metabolic effects of habitual sleep restriction. Thus, in this cross-sectional community-based study, we assessed the relationship of usual sleep time duration to DM-2. Objectives: To study the prevalence of DM-2 and impaired fasting glucose (IFG) in Bareilly city and to study the association of sleep time duration of the study subjects with DM-2.

To study the prevalence of DM-2 and impaired fasting glucose (IFG) in Bareilly city and to study the association of sleep time duration of the study subjects with DM-2.

A cross-sectional study was conducted using multistage random sampling technique in Bareilly City, Uttar Pradesh, India, from March to August 2016. Fasting blood glucose analysis was done by taking early morning blood sample by finger pricking method using Accu-Chek Active Glucose Monitor and its strips. Diabetes was considered if fasting plasma glucose (FPG) value was >126 mg/dL and impaired plasma glucose (IFG) was considered if FPG value was 110 to 125 mg/dL.

The results were compiled and analyzed in IBM Statistical Package for the Social Sciences (SPSS) Statistics version 22.0. The p-value less than 0.05 was taken as statistically significant.

Prevalence of DM-2 was 17.69%, and the prevalence of IFG was 13.1% in the present study. Out of a total of 130 study subjects, 31 subjects were sleeping 6 hours or less per night, and out of these, 13 (41.9%) subjects were diagnosed with DM-2, and other 13 subjects (41.9%) were diagnosed with IFG. The remaining 99 (76.2%) subjects were sleeping 7 to 8 hours duration per night, and among these, only 13.1% were diagnosed with DM-2, and 18.2% were diagnosed with IFG. Finally, it was analyzed and observed in this study that both DM-2 and IFG were significantly associated with sleep restriction in the study subjects.

The sleep duration of 6 hours or less is associated with increased prevalence of DM-2 and IFG. Because this effect was present in subjects without insomnia, it can be concluded that voluntary sleep restriction may contribute to the large public health burden of DM-2 in the urban community.
