Values are: Standardized β coefficients (Unstandardized β coefficients). Model adjusted for age, race, financial strain, menopausal status, use of medications that could affect sleep, body mass index, and depressive symptoms.
Natural log transformed prior to analyses. For dummy-coded variables (i.e., marital history), the unstandardized β coefficient indicates the value of the increase or decrease in the predicted outcome relative to the referent group (consistently married), after adjustment for covariates.
Higher scores reflect greater movement during the sleep period (range 0-150);
P ≤ 0.05;
P ≤ 0.01;
P ≤ 0.001
