Abstract

Kratki upitnici su sve više korišteni alati za brzu procjenu kvalitete prehrane. U ovom istraživanju je razvijen novi upitnik "analiza prehrane" s 18 pitanja podijeljenih u 3 kategorije (vrijeme ispunjavanja 3-5 minuta). Cilj je bio usporediti relativnu valjanost ovog upitnika s indeksom pravilne prehrane mHEI-2015, na temelju 7-dnevnog dnevnika prehrane koji su popunili 46 ispitanika (19-66 godina). Rezultati su pokazali pozitivnu korelaciju (Pearsonov koeficijent R = 0,66) između ove dvije metode procjene. Bland-Altmanov plot je pokazao da su podaci uglavnom uniformno raspoređeni, osim za dva ispitanika koji su odstupali. Razlika u bodovima između metoda je bila u rasponu od -6% do 37%. Većina ispitanika (69,5%) je imala razliku u bodovima manju od jedne standardne devijacije, što ukazuje na malu varijabilnost među njima. Rezultati sugeriraju da se ove dvije metode slažu u procjeni prehrambenih navika većine ispitanika. Predložene su izmjene u bodovanju upitnika "analiza prehrane" na temelju američkih prehrambenih smjernica i rezultata ovog istraživanja.

Abstract (english)

Short questionnaires are increasingly used tools for quickly assessing dietary quality. In this study, a new questionnaire called "diet analysis" was developed, consisting of 18 questions divided into 3 categories (completion time: 3-5 minutes). The objective was to compare the relative validity of this questionnaire with the Healthy Eating Index mHEI-2015, based on a 7-day food diary completed by 46 participants (aged 19-66 years). The results showed a positive correlation (Pearson's coefficient R = 0.66) between these two assessment methods. The Bland-Altman plot demonstrated that the data were mostly uniformly distributed, except for two participants who deviated. The difference in scores between the methods ranged from -6% to 37%. Most participants (69.5%) had score differences within one standard deviation, indicating low variability among them. The results suggest agreement between these two methods in assessing the dietary habits of most participants. Proposed modifications to the scoring of the "diet analysis" questionnaire are based on American dietary guidelines and the findings of this study.
