Abstract:
Objective:To provide baseline data for the development of physical activity and health promotion strategies and public health policy among Chinese children and adolescents by systematically evaluating accelerometermeasured moderatetovigorous physical activity (MVPA) and sedentary behavior(SB).
Methods:The study search was carried out using China National Knowledge Infrastructure, SPORTDiscus with Full Text, and Web of Science, including studies that published from January 1, 2009 to February 28, 2019. The studies were selected by inclusion (based on PICOS principles) and exclusion criteria, and were assessed through quality assessment items based on revised STROBE statement. The information about MVPA and SB were extracted, and Comprehensive Metaanalysis Software (CMA V2) was used to pool the findings from the included studies into a Metaanalysis.
Results:Sixteen studies published from 2012 to 2019 were included the Metaanalysis. Sample sizes of eligible studies ranged from 96 to 2 163 participants. Metaanalysis found that Chinese children and adolescents separately spent 37.66 min/day, 539.61 min/d in MVPA and SB. Boys were more likely to have higher level of MVPA in minutes compared to the girls’(P<0.01). Children and adolescents spent more time in MVPA on weekdays than weekends(P<0.05), and also spent more SB on weekdays than weekends(P<0.05).
Conclusion:Chinese children and adolescents are physically inactive and live a sedentary lifestyle in general, especially among girls. MVPA and SB time among children and adolescents spent on weekdays are higher than weekends.
