Subgroup analyses of the associations between nocturnal sleep duration and the risk of hyperuricemia were performed using logistic regression models based on gender, age, and chronic conditions (hypertension, dyslipidemia, DM, and obesity). All models were adjusted for marital status, education level, annual household income, work intensity, sedentary time, position levels, participating in physical exercise, smoking, drinking, having mood symptoms, irregular meal habits, midnight snacks, using hypnotics, nap duration, and were adjusted for gender, age, obesity, DM, hypertension, and dyslipidemia as appropriate. Point estimates for odds ratios are shown as small squares, while the 95% CIs are shown as horizontal lines. The small green squares represent sleep duration of <7 h/night, the blue represents sleep duration of 8–9 h/night, the red represents sleep duration of 9–10 h/night, and the black represents sleep duration of ≥10 h/night.
