Sleep status and the associated factors, a large cross-sectional study in Shaanxi province of China
Abstract Background This study aimed at investigating the sleep status and its associated factors in Shaanxi province of China. Methods This cross-sectional study was conducted among 11399 subjects in Shaanxi Province, China. Data was collected via spot field questionnaire survey. The contents included demographic characteristics, sleep status, lifestyles, disease history and other associated factors. Logistic regression analysis was used to estimate the effect of associated factors for sleep quality. Crude odds ratio (cOR) and adjusted odds ratio (aOR) and their 95% confident intervals (CI) were calculated. Results A total of 11036 subjects were included in the final analysis. There were 12.8% participants having a bad or very bad sleep. In the last month, 8.4% participants had difficulty in initiating sleep, 7.6% participants had difficulty in maintaining sleep, 8.8% participants suffered from awakening earlier and 10.3% participants had the problem of feeling sleepy during the day ≥ 3 times per week. There were 16.5% participants having one of the above sleep problems (difficulty in initiating sleep, difficulty in maintaining sleep, awakening early) > 3 months. Poorer sleep quality was associated with female (aOR = 1.792, p < 0.001), unmarried or without cohabiting with boyfriend/girlfriend (aOR = 1.319, 95% CI = 1.022–1.704), divorced or widowed (aOR = 1.436, 95% CI = 1.052–1.960), heart diseases (aOR = 1.478, p = 0.002), musculoskeletal diseases (aOR = 1.460, p = 0.018), concerning about their own health (aOR = 1.113, p = 0.016), alcohol drinking (aOR = 1.201, p < 0.001), taking hypnotics (aOR = 1.643, p < 0.001), a longer daily screen time (aOR = 1.055, p < 0.001). Better sleep quality was associated with medium education level (aOR = 0.748, p = 0.003), high family monthly income (aOR = 0.939, p = 0.004), good self-reported health status (aOR = 0.490, p < 0.001), having breakfast regularly (aOR = 0.935, p = 0.016). Conclusions The self-reported sleep quality was generally good in Shaanxi, China. Sleep quality was associated with gender, marital status, educational level, family monthly income, heart disease, musculoskeletal diseases, degree of concerning about their own health, self-reported health status, alcohol drinking, having breakfast, take hypnotics and daily screen time.
