Trajectories in Physical Activity and Sedentary Time Among Women Veterans in the Women's Health Initiative.

ABSTRACT:

Purpose of the study

Trajectories of physical activity (PA) and sedentary time (ST) after military separation are likely important determinants of women's health outcomes later in life, because low PA and high ST are known contributors to premature mortality risk. Our objective was to compare longitudinal trajectories of recreational PA and ST between Veteran and non-Veteran postmenopausal women from the Women's Health Initiative (WHI).

Design and methods

Women Veteran (n = 3,719) and non-Veteran (n = 141,800) WHI participants were included. Self-reported participation in recreational PA, converted to metabolic equivalent (MET)-hours/week, was prospectively assessed over 8 years. Self-reported ST, defined as hours/day sitting or lying down, was collected at baseline and at Y
