Accelerometer-Measured Physical Activity and Sedentary Behavior in Relation to All-Cause Mortality: The Women's Health Study
Physical inactivity is estimated to cause as many deaths globally each year as smoking. Current guidelines recommend ≥150 min/wk of moderate-intensity aerobic physical activity (PA) and muscle-strengthening exercises on ≥2 d/wk.2 These guidelines are based primarily on studies using self-reported moderate- to vigorous-intensity PA (MVPA). Technological developments now enable device assessments of light-intensity PA (LPA) and sedentary behavior, and well-designed studies with such assessments that investigate clinical outcomes are needed for updating current guidelines. Here, we present data from the WHS (Women's Health Study). (The data, analytical methods, and study materials will not be made available to other researchers for purposes of reproducing the results or replicating the procedure.)
