OBJECTIVE We examined the associations of objectively measured sedentary time and physical activity with continuous indexes of metabolic risk in Australian adults without known diabetes. RESEARCH DESIGN AND METHODS An accelerometer was used to derive the percentage of monitoring time spent sedentary and in light-intensity and(More)
PURPOSE This study aimed to describe the scope of accelerometry data collected internationally in adults and to obtain a consensus from measurement experts regarding the optimal strategies to harmonize international accelerometry data. METHODS In March 2014, a comprehensive review was undertaken to identify studies that collected accelerometry data in(More)
OBJECTIVE To examine the prospective association between objectively measured time spent sedentary and insulin resistance and whether this association is independent of moderate- and vigorous-intensity physical activity (MVPA) and other relevant confounders. RESEARCH DESIGN AND METHODS This was a population-based study (Medical Research Council Ely study)(More)
BACKGROUND Television viewing (TV), a highly prevalent behaviour, is associated with higher cardiovascular risk independently of physical activity. The relationship with mortality, however, is relatively unknown. METHODS We examined the prospective relationship between TV time and all-cause, cardiovascular and cancer mortality in a population-based cohort(More)
BACKGROUND Although television viewing time is detrimentally associated with intermediate cardiovascular risk factors, the relationship with incident total (i.e. combined fatal and non-fatal) cardiovascular disease (CVD), non-fatal CVD and coronary heart disease is largely unknown. This study examined whether television viewing time is associated with these(More)
PURPOSE Television viewing time, independent of leisure time physical activity, has cross-sectional relationships with the metabolic syndrome and its individual components. We examined whether baseline and 5-yr changes in self-reported television viewing time are associated with changes in continuous biomarkers of cardiometabolic risk (waist circumference,(More)

OBJECTIVE To investigate the relationship of body weight and its changes over time with physical activity (PA). DESIGN Population-based prospective cohort study (Norfolk cohort of the European Prospective Investigation into Cancer and Nutrition, EPIC-Norfolk, United Kingdom). SUBJECTS A total of 25 639 men and women aged 39-79 years at baseline. PA was(More)
The reliability and validity of a physical activity computer questionnaire of a usual week were studied in 33 adolescents between 12 and 18 years of age. Intraclass correlation coefficients and Kappa values were calculated to verify test-retest reliability. Validity was investigated by calculating Pearson correlation coefficients between the questionnaire(More)
