Ocena prehranskega vnosa in porabe energije s telesno dejavnostjo pri petnajstletnikih z različno sestavo telesa

Med mladostniki že več let beležimo porast neustreznega prehranskega vnosa in telesne nedejavnosti. V prejšnjih študijah so se avtorji osredotočili predvsem na posamezne učinke prehranskih navad in posledic (ne)zadostne telesne dejavnosti. Da bi ugotovili, kateri od teh dveh dejavnikov ima večji učinek na telesno sestavo, ki je en od pomembnejših pokazateljev zdravstvenega stanja, smo se osredotočili na ta dva dejavnika v isti študiji. Podatke smo pridobili v okviru večje študije z naslovom Analiza razvojnih trendov otrok v Sloveniji 2014 (ARTO.Si). Zbrali smo podatke o telesni dejavnosti, antropometrične podatke in podatke o prehranskem vnosu. Mladostnike smo najprej razdelili v tri skupine (podhranjeni, normalno hranjeni, prekomerno hranjeni) glede na njihovo telesno sestavo. Nato smo za vsakega posameznika izračunali čas porabljen za zmerno in visoko-intenzivno telesno dejavnost na dan ter izračunali HuSKY indeks, ki temelji na vnosu hrane. Parametrične podatke smo analizirali z analizo variance, medtem ko smo za neparametrične uporabili Hi kvadrat test. Rezultati so pokazali, da je skupina mladostnikov z optimalno sestavo telesa bolj telesno dejavna, kot skupina mladostnikov z neoptimalno sestavo telesa, (ne)primernost prehranskega vnosa pa je v obeh skupinah mladostnikov podobna.

• Title: Assessment of dietary intake and energy consumed with physical activity in fifteen-year-olds with different body composition

Abstract

The trend of inappropriate diet and lack of physical activity among adolescents has been reported to increase for several years. What makes this fact alarming, is not only the current health and well-being of the adolescents, but also the health risks these individuals will face at higher age. In previous studies, the authors focused primarily on either individual effects of dietary habits, or on the consequences of (in)sufficient physical activity. In order to identify, which of these two factors has a greater effect on body composition in adolescents, we focused on these two factors in a single study. Data were collected within a larger study entitled “Analysis of Children’s Development in Slovenia” (ACDSi). Data on weekly physical activity, anthropometric, and nutritional data were collected. Adolescents were first divided into three groups (underweight, optimal, and overweight) according to their body composition. Then, daily time for their moderate and vigorous physical activity and HuSKY index, based on food intake, were calculated. Parametric data were analyzed with analysis of variance and non-parametric data with Chi square test. Results showed that adolescents with optimal body composition were more physically active than those with non optimal body composition. However the (in)appropriate dietary habits were similar in both groups of adolescents.
