Aim To examine the association between self-reported physical activity and self-reported screen based time. Materials and methods 969 high school students filled in a questionnaire on physical activity and screen based activities. Correlation analysis between time spent in moderate/vigorous physical activities and time spent in screen based activities were performed. Results No association was found between physical activity and time spent watching TV, playing or using computers. A low correlation was found between time using mobile phones and time spent performing moderate physical activities (r = 0.09, p < 0.05), and vigorous physical activities (r = 0.13, p < 0.05). Conclusions These findings suggest that screen time is not displacing physical activity.
