Abstract

Introduction: Since sleeplessness and oversleeping are known to have adverse effects on human health, this study designed to compare sleep quality among non diabetic persons, those with impaired fast blood glucose and/or impaired glucose tolerance and diabetics. Materials and Methods: In a cross sectional study, 834 participants including 384 diabetics, 245 subjects with impaired fast blood glucose and/or impaired glucose tolerance) and 205 healthy persons were studied, and data was collected using standardized questionnaires and laboratory assessments. MANCOVA test was conducted to analyze the data using SPSS version 16. Results: Of the participants, 73% were women. Mean±SDs of age and BMI were 48.4±8.6 years and 29.2±4.5, respectively. Mean±SD for sleep qualities were 6.5±3.6 in diabetics and 5.8±3.3 in the others. Sleep disturbance score was meaningfully related to sex, age, educational levels, depression score, and glycosilated hemoglobin. Conclusion: Sleep disturbances in diabetics, especially women were more prominent than non-diabetics and significantly related to depression scores. Sleep hygiene and mental status, depression in particular, play crucial roles in diabetics and diabetes-prone individuals.
