Participants have been aged among 11 y and 20 y (M = 14.48; SD = 1.41), with 50.four (n = 832) getting boys and 49.6 (n = 818) becoming girls. Ultimately, with regard to the degree of representativeness in the sample, a final sampling error of 0.023 was obtained or, in other words, a two.37 margin of 4 of 15 error assuming a 95 confidence level.Youngsters 2021, 8, x FOR PEER REVIEWFigure 1.

This instrument was developed by Serra [69] primarily based on a prior study performed with young children and adolescents, denominated EnKid.

Instruments The present study employed the following instruments: the KIDMED questionnaire. This instrument was created by Serra [69] primarily based on a previous study carried out with children and adolescents, denominated EnKid. Following this, the KIDMED questionnaire was conceived of, comprising 16 queries developed to evaluate the adherence of respondents to a Mediterranean diet. Responses were recorded as optimistic (the respondent’s diet meets dietary behaviour guidelines and corresponds to a Mediterranean diet plan) or negative evaluations (the respondent will not adhere to this eating plan). Especially, the test was divided into 4 questions that had unfavorable connotations (-1), while the twelve remaining queries were evaluated having a optimistic score (+1). The outcome was interpreted as outlined by the following classification: (a) from eight to 12: optimal adherence, in other words the respondent consumes a Mediterranean eating plan to a big extent (high); (b) from four to 7: moderate adherence; the respondent is necessary to improve his/her dietary pattern so as to adopt the Mediterranean model (medium); (c) from 0 to three: extremely low-quality eating plan and, hence, very low level of adherence for the Mediterranean diet (low). The reliability on the original instrument was determined as = 0.854, as well as the present study obtained a lower index of = 0.523. It ought to be noted that this coefficient is comparatively low, which may very well be because of the lowered quantity of things and also the confusion generated by the things formulated inside the adverse sense. PAQ-A questionnaire: This questionnaire was developed by Mart ez [70] and is composed of 9 inquiries, which evaluate the physical activity performed by the adolescent throughout the seven days prior to administration. The regarded as physical activities contain that performed throughout free of charge time, physical education classes, extracurricular classes and activity engaged in in the weekend. Questions 1 to 6 offer details in regards to the forms of sport. Concerns 7 and 8 indicate physical activity intensity, alongside the frequency with which it is performed. Finally, Query 9 supplies further specific information pertaining to whether or not frequent engagement in physical activity was impeded for some reason. Responses have been recorded along a 5-point Likert scale. The internal consistency of this scale was = 0.77 inside the original study, with the present study getting.
