The prevalence of obesity （according to BMI） was 30.88% in urban children and 28.93% in rural children. Central obesity presented mainly in the rural girls. Approximately 90% of the participants reported 〈7 h of PA/week, regardless of residential area.

The results reflect the need to implement programs to improve PA conditions in the child urban-rural population.This study analyze the relation between body composition, physical activity （PA）, and sex in Chilean children from rural and urban public educational institutions.
