Abstract

Zaslađeni napici su vrlo popularni među adolescentima diljem svijeta, međutim, imaju nisku nutritivnu vrijednost. Cilj rada bio je utvrditi unos bezalkoholnih napitaka te istražiti povezanost konzumacije različitih vrsta napitaka i prehrambenog statusa adolescenata. Istraživanje je uključivalo 159 ispitanika dobi 17.8 ± 0.4 godina iz dviju srednjih škola. Prosječan dnevni energetski unos napicima je 215.5 kcal što čini 9.6% od ukupnog dnevnog energetskog unosa adolescenata. Energetskom unosu najviše doprinose sokovi (medijan=127.2 (95 % IP 124.0 – 185.2) kcal), pri čemu su gazirani napici najveći izvor energije i dodanog šećera. Adolescenti s prekomjernom tjelesnom masom unose više energije ledenim čajem u odnosu na one adekvatne tjelesne mase (p=0.020) dok među ostalim vrstama sokova ne postoji statistički značajna razlika. Učestalost konzumacije bezalkoholnih, a osobito zaslađenih napitaka među adolescentima je visoka, a kako se nalaze u kritičnom razdoblju rasta i razvoja pravilna prehrana igra vaţnu ulogu u sprječavanju kroničnih bolesti koje se javljaju u odrasloj dobi. Zato je potrebno ove napitke zamijeniti nutritivno vrednijim napicima (prirodni voćni sokovi, mlijeko) i vodom.

Abstract (english)

Sugar-sweetened beverages are very popular among adolescents worldwide, however, they have a low nutritional value. The aim of this study was to determine the intake of non-alcoholic beverages and explore the connection between the consumption of different types of beverages and nutritional status of adolescents. The study included 159 respondent aged 17.8 ± 0.4 years from two high schools. The average daily energy intake by beverages is 215.5 kcal which makes 9.6% of the total daily energy intake in adolescents. Energy intake is mostly boosted by the consumption of juices (median=127.2 (95% CI 124.0 – 185.2) kcal), by which carbonated drinks are the largest source of energy and added sugar. Compared to the adequate body weight adolescents, overweight adolescents intake more energy by drinking ice tea (p=0.020), whereas among other types of juices there was no statistically significant difference. The frequency of consumption of non-alcoholic beverages, especially sugar-sweetened beverages among adolescents is high, and because they are in a critical period of growth and development proper nutrition plays an important role in preventing chronic diseases that occur in adulthood. Therefore it is necessary to replace those beverages with nutritionally more valuable beverages (natural fruit juices, milk) and water.
