Data indicate the odds of engaging in a specific sleep hygiene behavior in those meeting criteria for insomnia or moderate-severity sleep-disordered breathing compared with those without the respective sleep disorder. Analyses adjusted for age, race, marital status, education, menopausal status, vasomotor symptoms, body mass index, use of medications that affect sleep, number of chronic health conditions, depressive symptoms, and polysomnographic total sleep time. ^*p<0.05; ^**p<0.01.
