Accelerometer-Measured Physical Activity and Mortality in Women Aged 63 to 99.

ABSTRACT:

Objectives

To prospectively examine associations between accelerometer-measured physical activity (PA) and mortality in older women, with an emphasis on light-intensity PA.

Design

Prospective cohort study with baseline data collection between March 2012 and April 2014.

Setting

Women's Health Initiative cohort in the United States.

Participants

Community-dwelling women aged 63 to 99 (N = 6,382).

Measurements

Minutes per day of usual PA measured using hip-worn triaxial accelerometers, physical functioning measured using the Short Physical Performance Battery, mortality follow-up for a mean 3.1 years through September 2016 (450 deaths).

Results

When adjusted for accelerometer wear time, age, race-ethnicity, education, smoking, alcohol, self-rated hea
