Model 1 was adjusted for age, gender, race/ethnicity, BMI and years of education. Model 2 controlled for the remaining 2 predictors in addition to the variables included in Model 1. B - regression coefficient reflecting the change in the dependent variable for:

a

1-point increase in the square-root transformed PSQI score;

b

1-h increase in measured sleep duration;

c

100,000-count increase in average daily body movement (bold numbers show significant associations). 95% CI - 95% confidence interval for B.
