Abstract


Introduction:

Diabetes remains a major public health problem and pose a challenge even today. More than the disease, complications associated with the disease necessitates frequent contact with the health care system for both prevention and management. Sleep is considered as one such essential factor. Physiological data suggests that short term partial sleep restriction leads to striking alterations in metabolic and endocrine functions including reduced carbohydrate tolerance, insulin resistance, increased sympathetic tone and increased cortisol concentration. In addition, patients with type 2 diabetes mellitus are reported to have higher rates of insomnia, excessive daytime sleepiness and a higher incidence of restless leg syndrome.      

Objective:The objective of the study is to identify the association of sleep disturbances among patients with type 2 diabetes in chennai population and to determine the pre­dictors of sleep impairment in this population using a validat­ed instrument, the Pittsburgh Sleep Quality Index (PSQI).

The Pittsburgh Sleep Quality Index questionnaire revealed that there was an increased incidence of poor sleep quality among diabetics (72%) compared to non-diabetics (28%) (p<0.001). Also there was an increased incidence of shorter duration of sleep (< 6 hours) among diabetics (61%) compared to non-diabetics (19%) (p<0.001).
