Background: to identify the prevalence and sociodemographic correlates of diferent domains of physical activity (PA) and higher sitting time among South American adolescents. Methods: data from national surveys of 11 South American countries were analyzed, and comprised information on 166,901 adolescents. PA (≥60 min/day of moderate-vigorous PA), physical education classes (PEC) (≥3 classes/wk), active commuting to school (≥1 d/wk), and higher sitting time (≥3 h/d) were self-reported. Sociodemographic correlates, such as gender, age, and food security status were explored using a random efect meta-analysis for logistic parameters. Results: recommended PA ranged between 7.5% (Brazil) and 19.0% (Suriname). Peru (2.2%) and Guyana (43.1%) presented the lowest prevalence of PEC and active commuting to school, respectively. Higher sitting time was less prevalent in Bolivia (24.6%) and more prevalent in Argentina (55.6%). Compared to girls, boys were more prone to reach recommendations for PA [OR=1.94(1.65;2.28)]; to reach≥3 PEC [OR=1.17(1.04;1.33)] and to be active in commuting to school [(OR=1.14(1.06;1.23)], but less prone to higher sitting time [(OR=0.89(0.82;0.96)]. Older adolescents had less odds of reach PA guidelines [OR=0.86(0.77; 0.97)] and accumulated higher sitting time [OR=1.27(1.14;1.41)]. Adolescents with food insecurity reported more PEC [OR=1.12(1.04;1.21)] and active commuting to school [OR=1.12(1.02;1.22)] but had less higher sitting time than their food security pairs [OR=0.89(0.81;0.98)]. Conclusions: few adolescents reach the PA recommendation. Actions aiming the promotion of PA and the reduction of sitting time must consider girls and older adolescents as target groups, as well as the specifcs of each country. [--]
