To determine if 7 d physical activity (PA) predicts energy intake over the same days and if PA on a given day predicts energy intake on the same day, the next day or subsequent days. A 7 d prospective investigation. PA was measured using accelerometers worn for seven consecutive days. During the ...
Background: The current guidelines for aerobic activity require that adults carry out ≥150 min/week of moderate-intensity physical activity, with a large body of epidemiological evidence showing this level of activity to decrease the incidence of many chronic diseases. Less is known about whether light-intensity activities also have such benefits, and ...
Purpose To examine characteristics of accelerometer-assessed sedentary behavior among older women. Methods An ancillary study to the Women’s Health Study is collecting 7 days of accelerometer-assessed (Actigraph GT3X+) physical activity and sedentary behavior data in ~15,000 women. This analysis includes data from the first 5,032 (mean age, 70.1 yr) women with ≥4 days ...
Assessing physical activity (PA) with wearable sensors in epidemiologic studies often requires initializing activity monitors at the study site and mailing them to participants. In these studies, it is important to discern true PA data from mail transit data. Typically, participants are asked to log the date and time they ...
