Association between sleep duration and fair/poor self-rated health (SRH) in the whole population

Sleep duration	Weighted prevalence of fair/poor SRH, %	Age, sex-adjusted OR (95% CI)†	Multivariable OR (95% CI)*†
Whole population (n = 20,663)
≤ 5 h	23.4	3.84 (3.18-4.62)	2.29 (1.86-2.83)
6 h	13.8	2.01 (1.71-2.35)	1.68 (1.42-2.00)
7 h	7.5	1 (Referent)	1 (Referent)
8 h	12.1	1.59 (1.37-1.84)	1.38 (1.18-1.61)
≥ 9 h	23.8	3.10 (2.63-3.66)	1.98 (1.63-2.40)

OR, odds ratio; CI, confidence interval.

^*Adjusted for age (years), sex (female, male), race-ethnicity (non-Hispanic white, non-Hispanic blacks, Mexican Americans, others), education (< high school, high school, > high school), smoking categories (never, former, current), alcohol intake (never drinker, former drinker, current light drinker, current moderate drinker, current heavy drinker), body mass index categories (normal, overweight, obese), no exercise (absent, present), depression categories (absent, chronic, not chronic), diabetes (absent, present), hypertension (absent, present), cardiovascular disease (absent, present).

^†The sample size for the age, sex-adjusted, and multivariable models are the same.
