Data were provided by 8425 participants.
a,bMedian values in the same column with unlike superscript letters were significantly different (P<0·05).
The independent-samples Kruskal–Wallis test, followed by pairwise comparisons, was used to test for differences in alcoholic beverage intake and percentage energy from alcoholic beverages between quintiles.
One standard drink contains 10 g of alcohol( 27 ).
Percentage of total energy from alcoholic beverages includes energy from soft drinks mixed with alcoholic beverages where applicable.
