The objective of this review is to investigate the effectiveness of interventions to promote physical activity (PA) among children and adolescents in Asian countries. Systematic review. A systematic search of eight electronic databases was performed to retrieve articles published between January 1990 and August 2019, in English language, including any interventions to promote PA outcomes among children (aged 3–12 years) and adolescents (aged 13–18 years) in Asian countries. Thirty studies met the eligibility criteria and were included. Most studies were school-based (70%, n = 21), and half were cluster randomized controlled trials (53%, n = 16). Twelve of 30 included studies were among children, 15 among adolescents, and three among both children and adolescents. Only four studies (13%) used device-based measures of PA. The duration of intervention ranged from one day to 60 months (median 4.5 months). Twenty-one studies were of moderate-to-high quality, of which 15 demonstrated significant increases in PA behavior or physical fitness. Evidence was found that school-based, short-term (up to six months) interventions with a single or multicomponent approach including PA sessions, physical education, health education, and/or educational materials may increase overall PA in Asian children and adolescents. The present review provides some evidence supporting the effectiveness of interventions in promoting PA-related outcomes. However, the findings are inconsistent due to the low number of studies, low-methodological quality, and/or small sample size. Well-designed interventions are needed to inform strategies to enhance PA engagements among children and adolescents in Asia.
