  • Model 1: adjusted for age, race, sex, BMI, and sampling weight. Model 2: adjusted for age, race, sex, BMI, sampling weight, smoking, alcohol consumption, depression symptoms, and SDB. The interaction between insomnia and sleep duration was not statistically significant. Thus, these two variables were entered into the model separately, except for model 3, in which the results were adjusted for each other.
