| Popis: | AIM: Drinks can contribute to energy as well as micro‐ and macro‐nutrient intake. Drink‐specific, validated, quick and easy to administer questionnaires are needed to monitor secular trends in beverage consumption for different populations. The aim of the present cross‐sectional study was to develop and validate a drink‐specific questionnaire for the Greek population. METHODS: A 41‐item semi‐quantitative drinks frequency questionnaire (DFQ) was developed and validated against 7‐day weighed food records, among young Greek adults. Wilcoxon ranks tests, Kendall tau‐b correlations and Bland–Altman plot were used to compare the two methods. Fifty‐nine Greek University students (28 males, 31 females) completed both methods. RESULTS: No difference was observed in total drinks intake between the two methods. The Bland–Altman plot showed that the two methods are likely to agree concerning the total drinks intake. Wilcoxon's rank test showed no significant differences between the two methods, except for the ‘whiskey/vodka/gin’ intake (P 0.61) was observed for most DFQ items, including low‐fat and chocolate milk, hot chocolate, Greek/espresso coffee, commercial tea, packaged fruit juices, wine, alcohol‐free beer, light cola‐type drinks and water (tap/bottled/sparkling). ‘Low’ agreement ( |
