Prevalence and risk factors associated with circadian syndrome in community-dwelling middle-aged to older adults: Based on health ecology model

Abstract

ObjectivesTo explore the prevalence and risk factors associated with circadian syndrome (CricS) in community-dwelling middle-aged to older adults. MethodWe performed a cross-sectional analysis of 13,516 participants from the China Health and Retirement Longitudinal Study (CHARLS). We used logistic regression to compute the odds ratios (OR) and 95 % confidence intervals (Cls), using covariates derived through the health ecology model. ResultsThe overall prevalence of CricS was 31.5 % (25.0 % males and 37.1 % females). With controlling all covariates, social isolation (OR 1.164, 95%CI 1.033–1.310), irritable mood (OR 1.689, 95%CI 1.488–1.917), fear responses (OR 1.546, 95%CI 1.262–1.894), chronic disease (OR 1.577, 95%CI 1.392–1.788), and financial debt (OR 0.806, 95%CI 0.657–0.990) were significantly correlated with increased CricS risk in males, whereas CricS syndrome was significantly associated with age (OR 1.285, 95%CI 1.214–1.361), married (OR 1.258, 95%CI 1.089–1.452), current drinkers (OR 0.835, 95%CI 0.716–0.974), social isolation (OR 1.175, 95%CI 1.065–1.296), irritable mood (OR 1.346, 95%CI 1.210–1.497), fear responses (OR 1.202, 95%CI 1.047–1.378), chronic disease (OR 1.363, 95%CI 1.225–1.517), chronic pain (OR 1.177, 95%CI 1.058–1.309), and universal basic income (OR 0.742, 95%CI 0.611–0.900) in females. ConclusionCricS is common in middle-aged to older adults, and health behavior factors have an important impact on CricS. The potential predictors identified for CricS should be further studied to prevent the occurrence of adverse health events in the presenium stage.
