Abstract

U epidemiološkim studijama koje se bave procjenom unosa hrane i prehrambenim navikama važno je koristiti precizne i pouzdane metode. Cilj ovog istraživanja bio je ispitati ponovljivost metode kvantitativnog upitnika o učestalosti konzumiranja namirnica (FFQ) za koje se pretpostavlja da su pozitivno ili negativno povezane s nastankom alergijskih bolesti dišnog sustava. U ovom ispitivanju sudjelovalo je ukupno 106 studenata (28 mladića i 78 djevojaka) prve godine studija Sveučilišta u Zagrebu. Prosječna dob ispitanika bila je 19 godina (raspon od 18 do 44 godine). Koeficijent Spearmanove korelacije tjedne učestalosti konzumiranja namirnica kretao se od 0,37 (P<0,001) za agrume do 0,77 (P<0,001) za soju, sa medijanom 0,59; ponderirane κ vrijednosti tjedne učestalosti konzumiranja namirnica kretale su se od 77,2 (P<0,001) za proizvode od integralnog brašna do 93,4 (P<0,001) za krumpir i bijelo vino sa medijanom 85. Metoda kvantitativnog upitnika o učestalosti konzumiranja hrane pokazala je dobru ponovljivost.

Abstract (english)

To investigate the relationship between diet and an outcome, epidemiologic studies must have a reliable and precise method for evaluating food intake. The aim of this study was to investigate the repeatability of the quantitative FFQ regarding foodstuff positively or negatively associated with the development of allergic respiratory diseases. The study involved 106 first-year students (28 boys and 78 girls) at the University of Zagreb. The mean age was 19 years (range, 18 to 44). Spearman rank correlation coefficients ranged from 0.37 (P <0.001) for citrus fruits to 0.77 (P <0.001) for soybeans, with the median 0.59, quadratic weighted κ values ranged from 77.2 (P <0.001) for products from wholemeal flour to 93.4 (P <0.001) for potatoes and white wine, with a median 85. The FFQ yielded good repeatability.
