Background: Physical activity (PA) levels among older adults are generally low and sedentary behaviour (SB) very common; increasing PA and reducing SB levels could have appreciable health benefits. Quantifying PA and SB patterns through the day could help in defining strategies for change. We examined within day variations in PA ...
Purpose: Previously, studies examining correlates of sedentary behavior have been limited by small sample size, restricted geographic area, and little socio-cultural variability. Further, few studies have examined correlates of total sedentary time (SED) and screen time (ST) in the same population. This study aimed to investigate correlates of SED and ...
Background: Excessive sitting time is linked to cardiovascular disease morbidity. To date, no studies have accurately measured sitting time patterns in people with stroke. Objective: To investigate the amount and pattern of accumulation of sitting time, physical activity and use of time in people with stroke compared to age-matched healthy ...
Abstract: The associations between time spent in sleep, sedentary behaviors (SB) and physical activity with health are usually studied without taking into account that time is finite during the day, so time spent in each of these behaviors are codependent. Therefore, little is known about the combined effect of time ...
Introduction: This study examined agreement between activPAL3 (AP) and ActiGraph (AG) wrist and hip cut-points for assessing sedentary behaviour (SB) among 5-12 year-old children using direct observation (DO) as the criterion. Methods: 30 children (9.2±2.1y, 53.3% boys) wore AG on both wrists and the right hip and a thigh-mounted AP while completing 15 5...
Purpose: Sit-to-stand workstations are becoming common in modern offices and are increasingly being implemented in sedentary behavior interventions. The purpose of this study was to examine whether the introduction of such a workstation among office workers leads to reductions in sitting during working hours, and whether office workers compensate for ...
Introduction: Sedentary behaviour (SB) is associated with a number of health outcomes, independent of physical activity. Studies that have used accelerometers to define SB tend to use a <100 counts per minute (cpm) threshold to define SB across all domains; however, this cut-point was not empirically derived. It is not ...
Background: Overweight and obese older adults have high sedentary time. We tested the feasibility and preliminary effects of a sedentary time reduction intervention among adults over age 60 with a body mass index over 27 kg/m2 using a nonrandomized one-arm design. Methods: Participants (N = 25, mean age = 71.4, mean body mass index = 34) completed ...
Background: Demographic, family, and home characteristics play an important role in determining childhood sedentary behaviour. The objective of this paper was to identify correlates of total sedentary time (SED) and correlates of self-reported screen time (ST) in Canadian children. Methods: Child- and parent-reported household, socio-demographic, behavioural, and diet related data ...
Background: Low levels of physical activity and high time spent in sedentary activities have been associated with unfavourable health outcomes in adolescents. During adolescence, physical activity declines and sedentary time increases, however little is known about whether the magnitude of these changes differs within or between school-time, after-school time, or ...
