Objective: Juvenile idiopathic arthritis (JIA) may cause functional impairment and reduced time engaged in physical activity. The aim of this study was to investigate the habits of patients with JIA regarding participation in club sports, leisure‐time physical activity, and school‐educational physical activity and relate this to objectively measured ...
Objective: Sedentary children have greater risk of developing abnormalities in glucose homeostasis. We investigated whether interrupting sedentary behavior (sitting) with very short periods of walking would improve glucose metabolism without affecting dietary intake in children with overweight or obesity. We hypothesized that interrupting sitting with short bouts of moderate-intensity walking ...
Abstract: This prospective study determined whether: (1) objective physical activity (PA) and sedentary (SED) time at 9 years was associated with cognition at 15 years, (2) cognition at 9 years was associated with PA and SED at 15 years, and (3) the change in PA and SED from 9 to 15 years was associated with the change in cognition. ...
Background: The growth and development that occurs in early childhood has long-term implications, therefore understanding the relevant determinants is needed to inform early prevention and intervention. The objectives of the study were to examine: 1) the longitudinal associations of physical activity and sedentary behavior with social skills and 2) how physical activity ...
INTRODUÇÃO: A avaliação objetiva do nível de atividade física em escolares é necessária para o diagnóstico e direcionamento de estratégias de promoção da saúde na escola. Todavia, barreiras operacionais, como a quantidade de aparelhos disponíveis e os longos períodos de ...
Background: The purpose of this study was to examine the convergent validity of the Polar Active Watch (PAW), a consumer-grade wrist-worn activity monitor, against waist- and wrist-worn research-grade monitors, the ActiGraph GT3X+/GT9X accelerometers, in children.
Methods: Fifty-one children (18 boys; mean age = 10.30 ± 0.91 years) wore the three monitors (PAW, ...
Objectives:
Physical activity (PA) can provide numerous physical and psychological health gains, yet a low proportion of children in England are sufficiently active to accrue benefit. Analyzing the correlates of PA from a socioecological perspective may help to identify factors that promote versus discourage PA. The purpose of the present ...
Objectives:
We investigated the impact of a standing desk intervention on daily objectively monitored sedentary behavior and physical activity in 6th grade school students.
Design:
Cluster non-randomised controlled trial.
Method:
Two classes (intervention students: n=22 [aged 11.8±0.4years]; control students: n=27 [11.6±0.5years]) from a public school in Lisbon were selected. The ...
Objectives:
Actigraphy is widely used to estimate sleep-wake time, despite limited information regarding the comparability of different devices and algorithms. We compared estimates of sleep-wake times determined by two wrist actigraphs (GT3X+ versus Actiwatch Spectrum [AWS]) to in-home polysomnography (PSG), using two algorithms (Sadeh and Cole-Kripke) for the GT3...
Objectives:
To determine whether sleep patterns (duration, timing, efficiency) differ by ethnicity.
Design:
Longitudinal study.
Setting:
Dunedin, New Zealand.
Participants:
A total of 939 children (48% male) aged 4-12 years (572 European, 181 Māori, 111 Pacific, 75 Asian).
Measurements:
All measurements were obtained at months 0, 12, and 24. Anthropometry was obtained using standard techniques, and parents completed ...
