Percentage who consumed an alcoholic beverage, their median intake and median percentage of total energy contribution, by day of the week, for adults aged 19 years and over using population-weighted, 1 d intake data from the Australian National Nutrition and Physical Activity Survey, May 2011–June 2012

a,b,cValues within a 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 prevalence, alcoholic beverage intake and percentage energy from alcoholic beverages between days of the week.
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.
