The Association Between Built Environment Attributes and Physical Activity in East Asian Adolescents: A Systematic Review

Asian adolescents living in Australia and England were found to be less active than their Western peers. We aimed to systematically examine evidence of the associations between attributes of the built environment and physical activity in adolescents dwelling in East Asian countries. A total of 10 electronic databases for relevant observational studies without time limit were searched. Five studies met the eligibility criteria, which involved a total of 43 817 schoolchildren aged 11 to 17 years. The majority of the built environment attributes measured was significantly associated with reported physical activity. Difficult access to public facilities was associated with physical inactivity. Inconsistent finding of the association between residential density and physical activity was found. Further studies comparing participants from different Asian countries using a longitudinal design with an appropriate period of follow-up and both objective and reported measures of built environment attributes and physical activity are needed.
