Objective: To explore the relationship between sleep status and the risk of diabetes in adults. Methods: The baseline data of 53 260 subjects who were aged 30-79 years and had been enrolled into China Kadoorie Biobank (CKB) study from Suzhou, Jiangsu province were analyzed. Multiple logistic regression models were used to investigate the association between sleep status and diabetes after adjusting for potential confounders. Results: Among 53 260 subjects, 5.3% had diabetes. The proportions of difficultly falling asleep, early morning arousal and snoring frequently was 7.2%, 10.0% and 29.5%, respectively. There were 22.6% of subjects reporting sleep duration ≤6 hours. After controlling for possible confounders, the subjects with difficulty falling sleep (OR=1.63 for male, 95%CI: 1.30-2.05; OR=1.48 for female, 95%CI: 1.27-1.73), early morning arousal (OR=1.37 for male, 95%CI: 1.12-1.68; OR=1.31 for female, 95%CI: 1.14-1.51) or snoring frequently (OR=1.16 for male, 95%CI: 1.00-1.34; OR=1.39 for female, 95%CI: 1.23-1.57) had a higher risk of diabetes. Using hypnotics regularly was associated with the risk of diabetes in females (OR=1.42, 95%CI: 1.06-1.92). Compared with 8 hours sleep duration daily, shorter sleep duration (≤6 hours) was associated with risk of diabetes in both males (OR=1.37, 95%CI: 1.17-1.60) and females (OR=1.24, 95%CI: 1.08-1.41). No statistical significant association was found between longer sleep duration (≥9 hours) and the risk of diabetes. Conclusion: Sleep problems, including difficulty falling asleep, early morning arousal, snoring frequently and shorter sleep duration, were associated with the risk of diabetes, but no statistical significant association was observed between longer sleep duration and the risk of diabetes.
