Methods: A school based cross sectional study was conducted and students were selected using two stage cluster sampling technique. Physical activity level and possible correlates were assessed using self administered questionnaires. Results: Out of total 1041 students, 49% was boys and mean age of the sample was 13.8 (0.4) years. Approximately 38% of adolescent school children were sufficiently active where 40% of boys and 36.4% of girls were sufficiently active. There was no significant difference between physical activity levels by gender. Approximately 47% of adolescents either walk or ride to school while 53% used public or own vehicles for schooling.Multivariate regression model controlling for confounders showed statistically significant associations of sufficient physical activity with type 1 AB or 1C schools; parents being physically active for >5 days per week ; thoughts and availability of active physical activity choices by adolescents when a recreational choice had to be made.Conclusions: The study findings suggest that physical activity level of adolescent school children of Rathnapura district need to be promoted.
