Sitting time and risk of cancer incidence and cancer mortality in postmenopausal women: the Women's Health Accelerometry Collaboration.

ABSTRACT:

Purpose

Few studies have explored whether accelerometer-measured sedentary behavior increases cancer risk. We examined the associations of accelerometer-measured daily sitting time and mean sitting bout duration classified by the Convolutional Neural Network Hip Accelerometer Posture (CHAP) machine-learned algorithm with incidence of any cancer, incidence of 13 physical activity-related cancers, and cancer mortality among postmenopausal women.

Methods

We used data from 22,097 women (mean age = 73.3 years, standard deviation [SD] = 6.7) in the Women's Health Accelerometry Collaboration, a consortium of two US-based cohort studies of postmenopausal women: the Women's Health Study and the Women's Health Initiative Objective Physical Activity and Cardiovascular Health Study.
