Outcome

Type Measure Description Time frame Safety issue
Other Blood pressure measurements Blood pressure was measured in a single occasion within the schools' settings using validated oscillometric devices 8 months No
Primary Overweight and obesity prevalence in a representative sample of primary schoolchildren aged 10-12 years old Assessment of overweight and obesity by measuring body weight and standing height. Body mass index was calculated by dividing weight (kg) by standing height squared (m2). Obesity and overweight among children were calculated using the International Obesity Task Force (IOTF) age and gender specific body mass index cut-off criteria 8 months No
Secondary Dietary intake assessment Dietary assessment was based on a validated self-reported, semi-quantitative picture-aid food frequency questionnaire (FFQ), consisted of 48 food items commonly used in the local Greek cuisine. 8 months No
Secondary Assessment of eating behaviors Assessment of the frequency of breakfast consumption and number of eating occasions (number of meals and snacks during the day), as well as the frequency of having meals in front of a screen (watching television/DVD/videos and/or using of games consoles/computer), and the frequency of having meals together with the whole family or at least with one family member. 8 months No
Secondary Assessment of physical activity and inactivity levels Physical activity levels assessment was performed by the Physical Activity Questionnaire for older Children. Children were also asked whether they had television or computer in their room and were asked to report the average weekdays and weekend time (h/d) spent on sedentary activities and more specifically on watching television/DVD/movies and/or recreational usage of games consoles/computer. 8 months No
