Purpose: Most studies of neighbourhood features examine singular neighbourhood attributes, which may pattern in different ways. This study aimed to identify typologies of neighbourhood attributes and their associations with physical activity among children. Methods: The homes of 808 children aged 5-6 and 10-12 years were mapped in a Geographic Information System. ...
Abstract: Active commuting to school (ACS) is an important source of physical activity for young people and may be helpful in fighting the obesity epidemic. However, children are subject to their parents restrictions and are not totally independent when choosing their active behaviors. The aim of this study is to ...
Purpose: The primary purpose of this study was to determine associations of accelerometer-assessed moderate- to vigorous-intensity physical activity (MVPA) and sedentary time with health-related quality of life (HRQoL) and physical function and well-being in colon cancer survivors. Methods: Colon cancer survivors (N=181) from Alberta, Canada (n=92) and Western Australia (n=89) ...
Background: Cardiovascular fitness (CVF) is a key determinant of health; however it is unclear what patterns of physical activity (PA) contribute to healthy levels of fitness in children. Therefore, we evaluated how patterns of PA and sedentary time are associated with CVF in school-aged children. Methods: Children (n=366, 8-11 yr) ...
Background: Too much or too little physical activity (PA) may increase risk of falls in older adults. To date, no studies have investigated how objectively-measured PA predicts falls in community-dwelling older adults. Methods: 1655/1708 (97%) men aged 71-91 years participating in an established UK population-based cohort study wore a GT3x accelerometer ...
Background: Observational studies and lab-based trials indicated protective effects of regularly interrupting sedentary time on cardio-metabolic health in adults. We examined associations of breaks in sedentary time with cardio-metabolic risk in children. Methods: We included 19,520 children (aged 4-18, 48% boys) from 14 studies participating in ICAD, providing data on cardio-metabolic risk (at ...
Abstract: The German National Cohort (GNC) is a joint interdisciplinary endeavour of scientists from the Helmholtz and the Leibniz Association, universities, and other research institutes. Its aim is to investigate the causes for the development of major chronic diseases, i.e. cardiovascular diseases, cancer, diabetes, neurodegenerative/-psychiatric diseases, musculoskeletal diseases, ...
Background: The purpose of this study was to determine the responsiveness of two motion sensors to detect change in sedentary behaviour (SB) and physical activity (PA) during an occupational intervention to reduce sitting time. Methods: SB and PA were assessed using a hip-worn Actigraph GTX3 (AG) and a thigh-worn activPAL (...
Objectives: To determine the amount of time children play outdoors and examine associations with weekday, weekend and after-school physical activity (PA), sedentary behavior (SB), and weight-status (normal-weight, overweight/obese). Methods: Data were extracted from Project BEAT (Toronto, 2010–2011; www.beat.utoronto.ca). Children's (n = 856; mean age = 11 ± 0.6 years) PA and SB were ...
Background: Childhood overweight/obesity and inadequate physical activity burden Western countries, and now, pose a growing threat to the health of children in low and middle income countries. Behavioural transitions toward more sedentary lifestyles coupled with increased consumption of high calorie foods has resulted in rising proportions of overweight/obesity ...
