^‡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
