Namen magistrskega dela je bil ovrednotiti prehransko znanje in vnos energije in hranil pri študentih. V raziskavi je sodelovalo 16 študentov (12 žensk in 4 moški) magistrskega programa Prehrana. Zanimala nas je tudi povezava med prehranskim znanjem in dejanskim prehranskim vnosom ter prehranskim statusom študentov. Prehransko znanje smo ovrednotili z Vprašalnikom o splošni in športni prehrani, ki je bil razdeljen na dva dela. Prvi del je obsegal 36 vprašanj o splošni prehrani, drugi del je obsegal 27 vprašanj o klinični športni prehrani. Vprašalnik je bil sestavljen iz vprašanj in trditev o posameznih virih hranil v živilih ter prehranskih mitih, pri tem so morali biti študenti kritični do podanih informacij in smiselno odgovoriti na vprašanja. Na vprašalniku znanja o prehrani so anketiranci v povprečju dosegli rezultat 92 %, s čimer so pokazali zelo visoko raven znanja. Na vprašalniku o klinični športni prehrani so bili anketiranci malenkost manj uspešni, saj je bil povprečen rezultat 84 %. Na podlagi rezultatov smo predlagali, da se kot spodnja meja za ustrezno znanje upošteva 80 % možnih točk. Pri študentih smo z vprašalnikom preučevali tudi uživanje prehranskih dopolnil. V drugem delu raziskave smo ovrednotili tridnevne prehranske dnevnike in določili energijski in hranilni vnos. Prehranski status študentov smo ocenili na podlagi pridobljenih rezultatov prehranskega vnosa in merjenja telesne sestave z bioimpedanco. Pri merjenju telesne sestave nas je zanimal predvsem fazni kot, ki je dober kazalnik prehranskega in funkcionalnega stanja posameznika. Odgovore anket, prehranske vnose in meritve telesne sestave smo obdelali s pomočjo statistične analize. Dobljene rezultate smo primerjali s priporočili, podanimi v Smernicah zdravega prehranjevanja za študente in Referenčnimi vrednostmi za energijski vnos ter vnos hranil. Anketiranci z boljšim prehranskim znanjem so imeli manjši vnos energije, povezave med prehranskim statusom in faznim kotom nismo potrdili. Rezultati raziskave so pokazali, da prehranska dopolnila uživajo vsi anketirani študenti, in sicer jih je večina (10) uživala vitamin D.

• Title: The correlation between nutrition knowledge and nutritional status of students

Abstract

The purpose of the master's thesis was to evaluate the nutritional knowledge and the intake of energy and nutrients among students. Sixteen students (12 women and 4 men) from the master's program in Nutrition participated in the study. We were also interested in the relationship between nutritional knowledge and actual dietary intake, as well as the nutritional status of the students. Nutritional knowledge was assessed using the General and Sports Nutrition Questionnaire, which was divided into two parts. The first part consisted of 36 questions about general nutrition, and the second part included 27 questions about clinical sports nutrition. The questionnaire comprised questions and statements about specific nutrient sources in foods and nutrition myths, requiring students to critically assess the information provided and answer the questions accordingly. On average, the respondents scored 92% on the nutritional knowledge questionnaire, demonstrating a very high level of knowledge. On the clinical sports nutrition questionnaire, the respondents were slightly less successful, with an average score of 84%. We also investigated the consumption of dietary supplements among students using a questionnaire. In the second part of the study, we evaluated three-day dietary records and determined energy and nutrient intake. The nutritional status of the students was assessed based on the obtained results of dietary intake and body composition measurements using bioimpedance. In the body composition measurements, we were particularly interested in the phase angle, which is a good indicator of an individual's nutritional and functional status. The survey responses, dietary intake, and body composition measurements were processed using statistical analysis. The results were compared with the recommendations provided in the Guidelines for Healthy Eating for Students and the Reference Values for Energy Intake and Nutrient Intake. Respondents with better nutritional knowledge had lower energy intake, but we did not confirm a relationship between nutritional status and the phase angle. The study results showed that all surveyed students consumed dietary supplements, with the majority (10) consuming vitamin D.
