Objective:To analysis the prevalence and characteristics of comorbid insomnia and sleep disordered breathing (SDB) in community population.Methods:This is a cross-sectional study. Cluster sampling was applied. Community residents in Shantou and Meizhou were investigated during April to May, 2021. Essential information collection, sleep related health investigation, and sleep study were conducted. Insomnia was defined as the insomnia severity index (ISI)≥8. A type Ⅳ wearable intelligent sleep monitor was applied for sleep study. Comorbid insomnia and SDB was defined as both diagnosis of insomnia and SDB. Statistical analysis was conducted by SPSS 25. Prevalence and characteristics of insomnia only, SDB only and comorbid insomnia and SDB were analyzed. Logistic regression was conducted to analyze the relationship between sleep disorders and unrestored sleep, abnormal glucose metabolism, hyperlipidemia, and cardiovascular disease.Results:There were 3 730 residents completed the investigation. The median age was 55.0 (46.0, 63.0) years. The prevalence of insomnia only, SDB only, and comorbid insomnia and SDB were 26.0%, 20.2%, and 10.4% respectively. The incidence of unrestored sleep in insomnia only and comorbid insomnia and SDB were 2.900 times and 3.777 times of that in no insomnia or SDB (both P<0.001); the risk of hyperlipidemia was elevated in insomnia only, SDB only and comorbid insomnia and SDB ( OR=1.553, 1.415, and 1.868; all P<0.05); the risk of cardiovascular disease increased 40.8% in SDB only ( P=0.001), and 42.1% in comorbid insomnia and SDB ( P=0.007), after adjusted by age, sex, body mass index (BMI), smoking, drinking, abnormal glucose metabolism, and hyperlipidemia. Stratified analysis revealed that young female (age<60 years) with normal BMI (<25 kg/m 2) and comorbid insomnia and SDB were associated with higher risk of cardiovascular disease. Female with normal body weight and insomnia only or comorbid insomnia and SDB were associated with higher risk of hyperlipidemia. Conclusions:The prevalence of comorbid insomnia and SDB is high in community population. Patients with comorbid insomnia and SDB present with more significant unrestored sleep, and are correlated with higher risk of hyperlipidemia and cardiovascular diseases.
