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: 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 ...
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 ...
Introduction: To establish the variability in the measurement of habitual physical activity (HPA) using the ActiGraph(R) GT3X+ accelerometer in children with cerebral palsy (CP). Method: Repeated measures: Independently ambulant children with unilateral CP (n=30; aged 11y3m [2y4m]) completed standardized tasks over two consecutive days wearing an ...
Objective: Prevalence of asthma and overweight has increased simultaneously during the past decades. Several studies have reported an association between these two health problems, but it is unclear whether this relation is causal. We hypothesize that children with asthmatic symptoms are less physically active, which may contribute to the development ...
Background: The primary aim of the International Study of Childhood Obesity, Lifestyle and the Environment (ISCOLE) was to determine the relationships between lifestyle behaviours and obesity in a multi-national study of children, and to investigate the influence of higher-order characteristics such as behavioural settings, and the physical, social and policy ...
Abstract: The ActiGraph accelerometer is commonly used to measure physical activity in children. Count cut-off points are needed when using accelerometer data to determine the time a person spent in moderate or vigorous physical activity. For the GT3X accelerometer no cut-off points for young children have been published yet. ...
Background and Aim: No prospective studies have investigated the association between physical activity (PA) and carotid subclinical cardiovascular disease across childhood. Therefore, the primary aim was to investigate the association between PA intensity across childhood and carotid intima media thickness (cIMT) and stiffness in adolescence. Second, we included a clustered ...
Background: Juvenile idiopathic arthritis (JIA), among the most common chronic diseases of childhood, can be associated with attenuated physical activity levels, reduced fitness, decreased functionality and pain. This pilot study aimed to determine the safety, feasibility and effect of a six week resistance training program in children with JIA. Methods: ...
