^a odds ratio (95% CI) for high frequency versus low frequency consumption among those living at ‘other’ accommodation compared to students living at parental home, analysis stratified by sex/country, each food group was analysed separately; numbers below 1 indicated that consumption among those not living at home was less common; similar numbers indicate similarities across the countries and by sex.

^† Frequent consumption defined as: several times a day/daily/several times per week.

* Frequent consumption defined as: several times a day/daily.
