Description
Summary:Introduction: The main Energy Balance-Related Behaviors’ (EBRB) in children and adolescents are: sedentary behavior (eg. screen time: TV, video games and computer), sugary drinks intake, having breakfast and daily physical activities (eg. active commuting to school, physical activity during recess, participation in sports and recreational physical activity) 1, 2. The sample size was calculated based on the experience of other multicenter projects, in which a feasibility pilot study was conducted previously, and the reliability and validity of the used method was evaluated4. According to the current recommendation level for PA, 90.2% (by questionnaire) and 92.9% (by accelerometer) of adolescents were classified as physically active.
