Purpose To compare associations between objective and subjective measures of moderate to vigorous physical activity (MVPA) & cardiometabolic biomarkers.
Methods 2174 (1110 boys) youth (12-19 years) from the 2003-6 NHANES combined surveys with self-reported MVPA (SRMVPA) in the previous 30 days & four 10-hour days of accelerometry MVPA (AMVPA) (Actigraph 7164) were included. The ...
Background Sedentary behavior has emerged as a novel health risk factor independent of moderate to vigorous physical activity (MVPA). Previous studies have shown self-reported sedentary time to be associated with mortality; however, no studies have investigated the effect of objectively measured sedentary time on mortality independent of MVPA. The objective ...
Statement of Problem Epidemiological studies examining the association between physical activity and sleep have relied on self-report measures of physical activity and have primarily been conducted in older adults. Therefore, to address these gaps in the literature, the purpose of the present study was to examine the association between objectively-measured ...
Introduction Cardio-metabolic risk factors are becoming more prevalent in children and adolescents. A lack of moderate-to-vigorous intensity physical activity (MVPA) is an established determinant of cardio-metabolic risk factors in children and adolescents [1]. Less is known about the relationship between sedentary behavior and cardio-metabolic health. Therefore, the objective was to examine ...
Aims Prolonged sedentary time is ubiquitous in developed economies and is associated with an adverse cardio-metabolic risk profile and premature mortality. This study examined the associations of objectively assessed sedentary time and breaks (interruptions) in sedentary time with continuous cardio-metabolic and inflammatory risk biomarkers, and whether these associations varied by ...
PURPOSE To describe physical activity levels of children (6-11 yr), adolescents (12-19 yr), and adults (20+ yr), using objective data obtained with accelerometers from a representative sample of the U.S. population.
METHODS These results were obtained from the 2003-2004 National Health and Nutritional Examination Survey (NHANES), a cross-sectional study of ...
Objective To examine the relationship between physical activity levels measured objectively by accelerometry and the use of mental health services (MHS) in a representative sample of males and females.
Method NHANES 2003-2004 is a cross-sectional study of the civilian, non-institutionalized US adult population. Participants reported whether or not they had ...
