BACKGROUND Epidemiological and objective studies report an association between sedentary time and lower risk of the metabolic syndrome (MetS) and its risk factors in young and middle-age adults. To date, there is a lack of objective data on the association between sedentary time and MetS among older adults. METHODS The association between objectively measured sedentary time (accelerometry) wi...

Measuring sedentary behaviour and physical activity with wearable sensors provides detailed information on activity patterns and can serve health interventions. At the basis of activity analysis stands the ability to distinguish sedentary from active time. As there is no consensus regarding the optimal cut-point for classifying sedentary behaviour, we studied the consequences of using different...

BACKGROUND The physical neighbourhood environment may influence adults' sedentary behaviour. Yet, most studies examining the association between the physical neighbourhood environment and sedentary behaviour rely on self-reported data of either the physical neighbourhood environment and/or sedentary behaviour. The aim of this study was to investigate the associations between objectively measure...

OBJECTIVE The aim of this study was to examine the association of sedentary behaviour patterns with frailty in older people. SETTING Clinical setting. DESIGN Cross-sectional, observational study. PARTICIPANTS AND MEASUREMENTS A triaxial accelerometer was used in a subsample from the Toledo Study for Healthy Aging (519 participants, 67-97 years) to assess several sedentary behaviour patter...

The objectives of this study were to (i) assess sedentary time and prevalence of screen-based sedentary behaviours of children with a chronic disease and (ii) compare sedentary time and prevalence of screen-based sedentary behaviours to ageand sex-matched healthy controls. Sixty-five children (aged 6-18 years) with a chronic disease participated: survivors of a brain tumor, haemophilia, type 1 ...

BACKGROUND Recent research has highlighted the need for increased evidence regarding the sedentary activity levels of preschoolers. Given the large proportion of time this population spends in various early learning facilities, the exploration of sedentary behaviors within this particular environment should be a priority. The purpose of the study was two-fold: (1) to compare sedentary time of p...

The term “sedentary” has historically been used to refer to individuals with low physical activity levels or not meeting some criterion level of physical activity. According to the recent findings, sedentary behaviour has been defined not simply as the absence of moderate-to-vigorous physical activity, but as a class of behaviours (e.g. sitting, watching TV or playing video games) characterized...

OBJECTIVES We used linked existing data from the 2006-2008 American Time Use Survey (ATUS), the Current Population Survey (CPS, a federal survey that provides on-going U.S. vital statistics, including employment rates) and self-reported body mass index (BMI) to answer: How does BMI vary across full time occupations dichotomized as sedentary/non-sedentary, accounting for time spent in sleep, oth...

BACKGROUND Sedentary time has been found to be independently associated with poor health and mortality. Further, a greater proportion of the workforce is now employed in low activity occupations such as office work. To date, there is no research that specifically examines the contribution of sedentary work to overall sedentary exposure and thus risk. The purpose of the study was to determine th...

BACKGROUND In the last decade, sedentary behavior has emerged as a new risk factor for health. The elderly spend most of their awake time in sedentary activities. Despite this high exposure, the impact of this sedentary behavior on the health of this population has not yet been reviewed. We systematically reviewed evidence for associations between sedentary behavior and multiple health outcomes...
