Background: The pediatric obesity epidemic has intensified the awareness of decreased physical activity and increased sedentary behavior as a major pubic health concern. While the research clearly shows ethnic disparities in obesity risk, very few have examined ethnic differences in physical activity. Most of these studies conducted were in ...
Background: Physical activity (PA) has long been associated with reduced all-cause and cardiovascular disease (CVD) mortality. More recently, time spent in sedentary behaviours has emerged as an independent risk factor for all-cause and CVD mortality. It is not well known if meeting PA guidelines reduces the amount of time spent ...
Background: Observational studies have shown that individuals can be both highly sedentary and highly active, and active people sit as much as those who do not meet the physical activity guidelines. It is not known how sedentary behavior changes in response to significant exercise training, such as training for ...
Background: Low levels of physical activity (PA) at workplace have been associated with massive time spent in sedentary behavior. It is known that sedentary behavior is directly associated with increased risk of cardiovascular disease, and risk of death from all causes. Purpose: To analyze the association of sedentary behavior and ...
Background: Sedentary behavior has been shown to be inversely associated with markers of insulin sensitivity and cardiometabolic health in middle-aged and older adults, independent of moderate-to-vigorous physical activity (MVPA). Low cardiorespiratory fitness (CRF) is an independent risk factor for cardiovascular disease (CVD) mortality, yet it is unknown whether CRF infl...
Background: Physical inactivity and sedentary time (ST) have been established as independent risk factors for chronic diseases, many of which are more common in males. Promoting physical activity (PA) and reducing ST in males can be challenging, and interventions targeting males are limited. Purpose: The purpose of this study was ...
Background: Post-menopausal women exhibit lower bone mineral density (BMD) and current health guidelines highlight the potential importance of reducing sedentary behavior (SB) to mitigate bone loss in this segment of the female population. Purpose: To determine if bone health status at the femoral neck (FN) and lumbar spine (LS) can ...
Background: The steep decline in physical activity (PA) among the oldest old is not well understood; there is little information about the patterns of change in PA and sedentary behaviour (SB) in older people. Longitudinal data on objectively measured PA data can give insights about how PA and sedentary behaviour (...
Background: Supportive care interventions are needed to reduce the chronic and late-appearing effects of breast cancer treatments. Reducing sedentary behaviour (SED) may be one promising strategy given the unique health benefits of low SED that are distinct from beneficial effects of moderate-to-vigorous intensity physical activity (MVPA). Objectives: To examine the ...
Objective: To assess the validity of the Global Physical Activity Questionnaire (GPAQ) for measuring sedentary behaviour (SB) in the Chilean adult population. Methods: 204 adults (88/116 male/female, 45.2±14.0) who were randomly selected during National Health Survey 2009-2010 completed the protocol. The participants wore an Actigraph GT3X (AG) for at least 7 consecutive ...
