TAPIA-SERRANO, Miguel Ángel; VAQUERO-SOLIS, Mikel; LOPEZ-GAJARDO, Miguel Ángel  and  SANCHEZ-MIGUEL, Pedro Antonio. Adherence to the Mediterranean diet, and importance in the physical activity and screen time in High School adolescents from Extremadura (Spain). Nutr. Hosp. [online]. 2021, vol.38, n.2, pp.236-244.  Epub May 24, 2021. ISSN 1699-5198.


in Spain, one third of the young people from 7 to 14 years of age are overweight or obese. Health-related behaviors such as a high level of physical activity, low screen time, and good eating habits can prevent overweight and obesity in young people.


to assess adherence to the Mediterranean diet and quality of food pattern in an adolescent sample from Extremadura (Spain).


the present research is a cross-sectional, descriptive study in 1566 adolescents aged 12-14 years, 857 boys (13.12 ± 0.89) and 709 girls (13.05 ± 0.82). Physical activity was measured through the physical activity questionnaire for adolescents (PAQ-A). Screen time was analyzed through the youth leisure-time sedentary behaviour questionnaire (YLSBQ). Adherence to the Mediterranean diet was calculated using the KIDMED questionnaire.


24.5 % of adolescents reported having good adherence to the Mediterranean diet. The youngest schoolchildren (p < 0.001) had a better eating pattern, with no difference between genders or body mass indices. Students who met recommendations for physical activity and screen time had greater adherence to the Mediterranean diet (p < 0.01).


results showed that most children and adolescents needed to improve their eating pattern. Participants who met the recommendations for physical activity and screen time showed greater adherence to the Mediterranean diet.
