BACKGROUND Physical activity (PA) declines during adolescence. There has been little research describing this decline or examining participation and nonparticipation in specific activities. OBJECTIVE To describe the pattern of change in the number of physical activities, the time spent on specific activities, and the stability of participation and(More)
UNLABELLED Accurate assessment of physical activity (PA) is necessary to identify the sedentary older individual who is in need of activity intervention. Activity monitors are quite popular, although it has been suggested that they are less accurate at slow gait speeds. PURPOSE To examine the accuracy of the three activity monitors in older individuals(More)
INTRODUCTION Month-to-month variation in physical activity levels in a cohort of postmenopausal women participating in a single site clinical trial undergoing lifestyle intervention was investigated before and after lifestyle intervention. METHODS Participants were Caucasian and African American women (mean age = 57.0 +/- 3.0 yr) from the Women on the(More)
OBJECTIVE The aim of this study was to determine whether changes in leisure time physical activity (LTPA) and body composition reflect concomitant changes in 400-meter walk time. METHODS Data were collected at the baseline and 48-month visits in the Women on the Move Through Activity and Nutrition study. At baseline, participants (n = 508) were randomized(More)
BACKGROUND Physical activity may play a role in preventing gallstone disease. METHODS The activity/gallstone relationship was examined in post-menopausal women from the Study of Osteoporotic Fractures (SOF; 1986-1988), a prospective study of fracture risk factors in 8010 women (mean age = 71.1 years, SD = 4.9). RESULTS Multivariate logistic regression(More)
BACKGROUND Accelerometers were incorporated in the 2003-2004 National Health and Nutritional Examination Survey (NHANES) study cycle for objective assessment of physical activity. This is the first time that objective physical activity data are available on a nationally representative sample of U.S. residents. The use of accelerometers allows researchers to(More)
BACKGROUND The relationship between obesity and physical function is not well understood. Physical activity may be a key factor impacting on the relationship between obesity and physical function. METHODS Subjects included 171 community-dwelling women (mean age = 74.3, SD = 4.3) participating in a 14-year follow-up study to a walking intervention trial.(More)
OBJECTIVE To examine whether simple anthropometric measures provide a good estimate of total and visceral fat in 146 community-dwelling, older white women (mean age, 74.0 +/- 4.1 years). RESEARCH METHODS AND PROCEDURES Total body fat and visceral fat were measured using electron beam computed tomography (EBT). Anthropometric parameters (height, weight,(More)
BACKGROUND A limited body of evidence, mostly based on self-report, is available regarding physical activity levels among American-Indian adults. PURPOSE This study aims to examine physical activity levels objectively using pedometers among a large cohort of American-Indian adult participants in the Strong Heart Family Study (SHFS). METHODS Physical(More)
