Comparison between the educational groups of each country and the total sample with Wilcoxon signed rank test. Rounded values are presented
aResponse categories: 1. Never 2. Less than one day per week 3. One day per week 4. 2-4 days a week 5. 5-6 days a week 6. Every day, once a day 7. Every day, twice a day 8.Every day, more than twice a day
bThe indicated amounts are derived from the sum of the respective question items; J3a and J3b and K3a, K3b and K3c for fruit juices amount and soft drinks amount respectively [31]. The variables are categorical with specific values of ml in each category
cResponse categories: 1.Not at all 2.30 min/day 3.1 h/day 4.2 h/day 5.2,5 h/day 6.3 h/day 7.3,5 h/day 8.4 or more h/day
d:the variables TV/PC time for weekdays and weekend-days are measured with an extra response category for 1,5 h/day (coded as 4); as such the items include 9 response categories
**, ***: significant within-group difference at .01 and .001 respectively
