Vancampfort D, Van Damme T, Firth J, et al. - In this analysis including adolescents (n = 142,118) from 48 low- and middle-income countries (LMICs) (age 13.8 ± 1.0 years; 49% girls), researchers focused on the identification of the correlates of physical activity (PA). They used data from the Global school-based Student Health Survey. Two groups of participants were defined: those who do (60 min of moderate-vigorous PA every day of the week) and do not comply with the World Health Organization recommendations. The prevalence of low PA was estimated to be 15.3%. The chance of meeting PA guidelines was more in boys and those who participated in physical education for ≥ 5 days/week, while less likelihood of having adequate levels of PA was observed in adolescents with food insecurity, low fruit and vegetable consumption, low parental support/monitoring, no friends, and who experienced bullying. Physical activity participation was identified as a complex and multi-dimensional behavior observed in adolescents aged 12 to 15 years residing in LMICs, which was determined by sociocultural, socio-economic, and policy-related factors.
