BACKGROUND Several reviews have summarized the research on correlates of older children's and adolescents' physical activity behaviors, but none have been published on preschool children. Over the past 27 years, a number of studies have investigated the correlates of preschool children's physical activity behaviors. It is timely and necessary to review the(More)
CONTEXT Identifying current physical activity levels and sedentary time of preschool children is important for informing government policy and community initiatives. This paper reviewed studies reporting on physical activity and time spent sedentary among preschool-aged children (2-5 years) using objective measures. EVIDENCE ACQUISITION Databases were(More)
BACKGROUND While parents are central to the development of behaviours in their young children, little is known about how parents view their role in shaping physical activity and screen time behaviours. METHODS Using an unstructured focus group design, parental views and practices around children's physical activity and screen time (television and computer(More)
CONTEXT Being physically active during the early years (age 0-6 years) is vital for healthy development. Identifying correlates and determinants of physical activity (PA) is crucial to guide effective interventions. This systematic review synthesized studies investigating potential correlates and determinants of PA during the early years, accounting for(More)
OBJECTIVES Little is known about how health behaviors such as physical activity (PA) and sedentary behaviors (SB) may be associated with psychosocial well-being during the crucial early childhood period. The aim of this study was to undertake a systematic review of associations between PA, SB and psychosocial well-being during early childhood. METHODS In(More)
BACKGROUND The prominence of sedentary behavior research in health science has grown rapidly. With this growth there is increasing urgency for clear, common and accepted terminology and definitions. Such standardization is difficult to achieve, especially across multi-disciplinary researchers, practitioners, and industries. The Sedentary Behavior Research(More)
OBJECTIVES Evaluate the predictive validity of ActiGraph energy expenditure equations and the classification accuracy of physical activity intensity cut-points in preschoolers. METHODS Forty children aged 4-6 years (5.3±1.0 years) completed a ∼150-min room calorimeter protocol involving age-appropriate sedentary, light and moderate-to vigorous-intensity(More)
IMPORTANCE Identifying associations between preschool-aged children's electronic media use and their later well-being is essential to supporting positive long-term outcomes. OBJECTIVE To investigate possible dose-response associations of young children's electronic media use with their later well-being. DESIGN, SETTING, AND PARTICIPANTS The IDEFICS(More)
BACKGROUND Sedentary behaviour has been linked with a number of health outcomes. Preschool-aged children spend significant proportions of their day engaged in sedentary behaviours. Research into the correlates of sedentary behaviours in the preschool population is an emerging field, with most research being published since 2002. Reviews on correlates of(More)
PURPOSE Little evidence exists about the prevalence of adequate levels of physical activity and of appropriate screen-based entertainment in preschool children. Previous studies have generally relied on small samples. This study investigates how much time preschool children spend being physically active and engaged in screen-based entertainment. The study(More)
