Background Studies have shown relationships between important health outcomes and sedentary behavior, independent of physical activity. There are known errors in tools employed to assess sedentary behavior. Studies of accelerometers have been limited to laboratory environments. Purpose To assess a broad range of sedentary behaviors in free-living adults using accelerometers ...
Purpose To describe the physical activity (PA) and sedentarybehaviors of postpartum Latinas who are overweight or obese prior to initiating Madres para la Salud, a social-support mediated walking intervention to promote postpartum weight loss. Methods 139 postpartum (13.6+/- 7.7 weeks since childbirth) women (age = 28.3 +/- 5.6 years and BMI = 29.7 +/- 3.5 kg[middle dot]...
Background During childhood and adolescence, both physical activity (PA) and sedentary behaviour seem to influence cardiorespiratory fitness (CRF); however, the combined association of PA and sedentary behaviour remains to be understood. We analysed the combined association of objectively measured sedentary behaviour and moderate-to-vigorous intensity PA (MVPA) on CRF in Portuguese ...
Background Sedentary behavior is associated with increased risk of chronic disease and sedentary behavior is increasing among adolescents. Data on changes in sedentary behavior in developing countries are limited. Purpose To describe 5-year longitudinal changes in nonschool sedentary hours among urban adolescents in Ho Chi Minh City, and to identify ...
Background and Purpose Research has shown that features of the home, work, and neighborhood environments are associated with sedentary and physical activity in adults. However, little is known about the extent to which objectively measured levels of sedentary and physical activity differ across these settings. According to behavior setting theory, ...
Aim This study aimed to compare the levels of objectively-measured sedentary behavior in children attending Montessori preschools with those attending traditional preschools. Methods The participants in this study were preschool children aged 4 years old who were enrolled in Montessori and traditional preschools. The preschool children wore ActiGraph accelerometers. Accelerometers were ...
Aim We aimed to study the sedentary behaviour and obesity levels in 123 students of the 7th grade and their implications in blood pressure levels. Methods Sedentary behavior and physical activity were assessed with accelerometry. Blood pressure was measured and for both systolic blood pressure and diastolic blood pressures Z-scores adjusted ...
Aim This study evaluated objectively measured physical activity and sedentary time among Finnish schoolaged children from grades 1 to 6 (ages 7 to 12 years) and compared the results between boys and girls, and between different age groups. Methods The study population consisted of 568 Finnish boys and girls from grades 1 to 6 (mean age 9.9 years, ...
Aim Some studies have analyzed the relation between sedentary behavior (SB) and body composition in children and adolescents. However most of the studies have used self-reported measures of SB and/or did not consider the potential confounding effect of physical activity in their analysis. The aim of this study was ...
Aim To examine the magnitude of associations between objectively-measured PA subcomponents and sedentary time with body composition in a large free-living population cohort of preschool children. Methods This was a cross-sectional study of 398 preschool children recruited from the Southampton Women's Survey. PA was measured by accelerometry and body composition by ...
