Purpose: Diabetes and sleep disorders are public health threats worldwide, but the potential association between them is still unclear.
Methods: We conducted a community-based cross-sectional study including 5078 participants (2665, 52.5% male) to determine the association between insomnia and diabetes mellitus prevalence.
Results: In patients with type 2 diabetes mellitus (T2DM) and nondiabetic controls, the prevalence of insomnia was 20.2% (68/377) and 12.2% (578/4741), respectively. The results showed that insomnia was associated with T2DM after adjusting for age, sex, BMI, smoking, alcohol consumption, presence of disease history (hypertension, dyslipidemia, stroke, cardiovascular diseases, cancers), and depression (odds ratio [OR] = 1.31, 95% confidence interval [CI] 1.03-1.66). After stratifying by age and sex, insomnia was significantly associated with diabetes mellitus only in the subgroup of middle-aged participants (40-59 years) (OR = 1.61, 95% CI 1.16-2.23) and males (OR = 1.48, 95% CI 1.08-2.03) after controlling for the above covariates.
Conclusions: This study suggests that insomnia is independently and significantly associated with diabetes mellitus in the northern Chinese population, especially in the 40-59-year-old age group and in males.
