A study published last year in the Journal of Nutrition Education and Behavior performed a cross-sectional study to determine any potential associations between adherence to the Mediterranean
diet, body weight, energy, and academic performance in Greek school-aged children.
528 primary schoolchildren between the ages of 10 and 12 years old (split relatively evenly between boys and girls) from 21 different schools in and around Athens, Greece were recruited for this study.
Activity levels, anxiety levels, self-esteem/self-perception levels, body image dissatisfaction, and dietary habits for each child were measured using self-reported questionnaires.
Academic performance was evaluated by the children’s teachers, who then completed questionnaires to be analyzed by the researchers.
Finally, height, weight, BMI, waist circumference, and abdominal obesity were measured for each child.
