Influence of sitting behaviors on sleep disturbance and memory impairment in breast cancer survivors.

ABSTRACT:

Background

The purpose was to prospectively examine the effects of sedentary behaviors on subjective memory impairment in breast cancer survivors (BCS) and the extent to which sleep disturbances mediated this pathway.

Methods

BCS (N = 380; M_age  = 57.38 ± 9.25 years) completed questionnaires assessing demographics, health history, sitting behaviors, sleep disturbance, subjective memory impairment, and moderate-to-vigorous physical activity (MVPA) at baseline and 6-month follow-up. A subsample (N = 300) wore an accelerometer to objectively estimate sedentary time and MVPA. Structural equation modeling was used to test direct and indirect effects of self-reported and objectively estimated sedentary behaviors on memory impairment (through sleep disturbance) across ti
