Geographic disparities in physical activity, sedentary behavior, sleep time, and gross motor skills in Nigerian preschoolers
Background Adherence to physical activity guidelines is crucial for children’s physical, social, and cognitive well-being. While previous research shows that about 77% of preschoolers meet the World Health Organization (WHO) physical activity guidelines, differences in outcomes based on geographic locations are unclear. This study examines disparities in physical activity, sedentary behavior, sleep, and gross motor skills between rural and urban …
The association between 24-h movement behaviours and adiposity among Australian preschoolers
Despite the association between more time spent in MVPA and higher BMI z-scores, promoting a balanced amount of time in each 24-h movement behaviour-more MVPA, less sedentary time, and sufficient sleep-remains important for overall health. Future studies should address methodological challenges (e.g. recruitment bias that may exist in the parents/children willing to participate versus the general population, recall bias in parent reported sleep d…
Accelerometer-Measured Physical Activity and Sedentary Time among Children in Japan before and during Covid-19
This study examined changes in physical activity (PA), sedentary behavior (SB), screen time, sleep, and executive function among Japanese preschoolers between COVID-19 pre-pandemic and pandemic periods, using cross-sectional and longitudinal data. Accelerometer data from 63 children aged 5-6 years were collected from three kindergartens in Tokyo, Japan, in late 2019 (pre-COVID-19). This was compared to the data of 49 children aged 5-6 years from …
The Impact of Covid-19 on Preschool-Aged Children’s Movement Behaviors in Hong Kong
During the COVID-19 pandemic, many preschool-aged children were forced to remain indoors due to social distancing measures and school closures. In this study, we examined how children's movement behaviors (sedentary behaviors, physical activity, and sleep) were affected by the pandemic. Children's ( N = 25, age = 4.4 years, SD = 0.3) movement behaviors were measured before and after the COVID outbreak, respectively. Data collected using accelerom…
Cross-Sectional and Longitudinal Associations between 24-Hour Movement Behaviours, Recreational Screen Use and Psychosocial Health Outcomes in Children
It remains unclear whether the time-use composition of 24-h movement behaviours (sleep, sedentary time (ST), physical activity (PA)) and recreational screen use are independently associated with psychosocial health. This study examined the cross-sectional and longitudinal associations between 24-h movement behaviour composition, recreational screen use and psychosocial health outcomes in children. Measures completed at baseline (n = 127; 11.7 yea…
Global effect of Covid-19 pandemic on physical activity, sedentary behaviour and sleep among 3- to 5-year-old children
PA and SST levels of children from LMICs have been less impacted by COVID-19 than in HICs. Ensuring children can access an outdoor space, and supporting parents' mental health are important prerequisites for enabling pre-schoolers to practice healthy movement behaviours and meet the Global guidelines
Physical Activity Promotion in Malaysia
About three quarters of the Malaysian adult population are physically active. There has been growth in physical activity and health research since 2010, with most studies being observational in design and few included objective measures of physical activity. The Malaysian Ministry of Health has published physical activity guidelines, strategies and action plans aimed at promoting physical activity. Physical activity promotion activities have incl…
Prevalence of Anaemia and Iron Deficiency among Primary Schoolchildren in Malaysia
The present study aimed to report the prevalence of anaemia and iron deficiency (ID) and to explore the associations among socio-demographic characteristics, nutritional status and inflammation status in the occurrence of anaemia and ID in a nationally representative sample of Malaysian primary schoolchildren. Using data from the South East Asian Nutrition Surveys (SEANUTS), 544 Malaysian children aged 7 to 12 years were included in this secondar…
