Considering the increasing public health concern the obesity in Morocco, the aim of the
present study was to use isotope techniques to assess body fat, total energy expenditure and
physical activity to inform design and improve interventions for the prevention and control
of obesity and related health risks such as diabetes and elevated blood pressure among
children and adolescents. Specific objectives of the trial: 1. Determine the extent of
obesity and physical activity levels in children and adolescents to design effective
interventions in the school setting. 2.Propose alternative field based techniques for
assessing body composition and physical activity that could be used in largescale situation
assessments and in assessing interventions to address obesity and risk related health care. *
For body composition: BMI z-score, waist circumference, waist measurement at height. * For
physical activity: Questionnaire, Accelerometers 3. To identify factors contributing to the
development of obesity and related health risks in schoolchildren and adolescents. 4.
Collaborate with stakeholders (government, schools and / or colleges, communities and
