Model 1 : single factor logistic regression.
Multivariate-adjusted model: adjusted for gender (male, female), age (<60 y, 60–75 y, ≥75 y), race (Han, others), marital status (single or divorced, married), tea consumption (no, yes), life stress (no, yes), current smoking status (no, yes), passive smoking (no, yes), current drinking status (no, yes), physical activity (no, yes) and body mass index (<18.5, 18.5–24, 24–28, ≥28).
We adjusted chronic diseases (no, yes) except all the confounders in Multivariate-adjusted model.
The reference group was normal sleeping quality group and participants who did not work on shift position.
