OBJECTIVES To investigate individual, behavioral, social and environmental correlates of physical activity (PA) and screen-based behaviors ([SBBs] TV viewing, electronic games playing and Internet use) in Chinese boys and girls in Hong Kong. DESIGN Cross-sectional study. METHODS PA and SBBs were self-reported among 303 children. Individual, behavioral,(More)
BACKGROUND Cross-sectional investigation showed that Chinese children in Hong Kong were more physically active on weekends than weekdays, which is contrary to previous findings. However, little is known as to whether these time-segment-specific differences persist with age. This study aimed to compare the 2-year changes in accelerometer-assessed physical(More)
PURPOSE This study examined the prospective associations of reallocating time spent in different types of sedentary behavior, physical activity, and sleep with body mass index (BMI) in children using isotemporal substitution analysis. METHODS Chinese children in grades 1-3 were recruited to a cohort study in 2009 and were followed up over a 2-yr period.(More)
A comprehensive understanding of research on the physical activity (PA) of Hong Kong youth is necessary to develop specific and effective intervention strategies. This review summarizes existing evidence in studies on PA among the Hong Kong youth. An electronic literature search was conducted using MEDLINE, SPORTDiscus, ERIC, and HighWire database.(More)
BACKGROUND Hong Kong's 2016 Report Card on Physical Activity (PA) for Children and Youth is the first evidence-based synthesis of various indicators related to individual behaviors that contribute to overall PA levels, settings and sources of influence, and strategies and investments in Hong Kong. METHODS Following a standardized protocol, currently best(More)
BACKGROUND Physical activity (PA) correlates have not been extensively studied in Hong Kong children. OBJECTIVE The aim of this study is to assess the validity and reliability of translated scales to measure PA related self-efficacy, enjoyment and social support in Hong Kong Chinese children. METHODS Sample 1 (n = 273, aged 8-12 years) was recruited(More)
BACKGROUND Relationships between the neighborhood environment and children's physical activity have been well documented in Western countries but are less investigated in ultra-dense Asian cities. The aim of this study was to identify the environmental facilitators and barriers of physical activity behaviors among Hong Kong Chinese children using nominal(More)
BACKGROUND Understanding patterns of time use of children is helpful in developing target-tailored intervention. The purpose of this study was to investigate the clustering of sedentary behaviours and physical activity in Chinese children and to examine the associations between sociodemographic factors and the time use clusters. METHODS Cluster analysis(More)
PURPOSE The purpose of this study was to (1) examine differences in fundamental movement skills (FMS) proficiency, physical self-concept, and physical activity in children with and without developmental coordination disorder (DCD), and (2) determine the association of FMS proficiency with physical self-concept while considering key confounding factors.
