ABSTRACT
Objective To investigate the relationship between sleep duration and obesity, and the risk of common chronic diseases in the occupational population in Shanghai City. Methods A total of 18 775 occupational individuals were selected as the study subjects using convenience sampling method in Shanghai City. Data on personal lifestyle behaviors and medical examination results were collected. The relationship between sleep duration and different types of obesity with dyslipidemia, hyperuricemia, hypertension, and hyperglycemia was analyzed. Results The incidence of dyslipidemia, hyperuricemia, hypertension, and hyperglycemia among the study subjects was 24.9%, 16.2%, 11.5%, and 7.3%, respectively. The incidence of these four chronic diseases were higher in individuals with central obesity and suboptimal sleep compared to the control group (all P<0.01). Multivariate logistic regression analysis showed that suboptimal sleep combined with general obesity/overweight increased the risk of dyslipidemia, hyperuricemia, hypertension, and hyperglycemia in the study subjects ［odds ratio (OR) were 2.40, 3.47, 3.30, and 2.79, respectively; all P<0.01］, after adjusting for age, gender, education level, marital status, occupation type, labor intensity, smoking, and drinking. Suboptimal sleep combined with central obesity also potentially increased the risk of these four chronic diseases (OR were 2.25, 3.09, 3.09, and 2.98, respectively; all P<0.01). Conclusion The incidence of common chronic diseases is relatively high in the occupational population in Shanghai City. Suboptimal sleep combined with different types of obesity increases the risk of common chronic diseases.
