Consumption of alcohol‐free and alcoholic beverages among Dutch university students: Substitution or addition?

Abstract

IntroductionAlcohol‐free drinks are suggested as healthy alternatives for alcohol consumption. To achieve benefits, alcohol‐free beverages must be consumed as a substitute for alcoholic beverages, not in addition. This study examined in a student sample (i) the frequency/quantity of alcohol(‐free) consumption; (ii) the relationship between alcohol‐free and alcohol consumption; (iii) alcohol‐free drinks as substitution or in addition to alcoholic drinks; and (iv) possible gender differences.MethodsSurvey data regarding alcohol(‐free) consumption (May–June 2022) of Dutch university students (N = 4.318, females 70.2%; males 28.5%, average age 22.6 years [SD = 2.4]).Results(i) A total of 42.8% of the students indicated they had never consumed alcohol‐free versus 10.1% who never consumed alcoholic beverages; (ii) the group who recently consumed alcohol‐free also most often recently consumed alcoholic beverages (42.7%). The group that had never consumed alcohol‐free drank on average more alcoholic beverages (M = 3.98 on a drinking day) compared to past and recent alcohol‐free drinkers (respectively, M = 3.44 and M = 3.59). (iii) Most students (54.9%) reported drinking alcohol‐free beverages in addition to alcohol, 17.4% indicated using it as a substitution. Students who consumed alcohol‐free as ‘substitution’ were older, more often living alone or with a partner, less often living with parents and more often involved in a steady relationship compared to students who consumed in ‘addition’. (iv) No prominent gender differences were found.Discussion and ConclusionsThe majority of students remained consuming the same number of alcoholic beverages since they started consuming alcohol‐free beverages, pointing to an addition effect. A small group did use alcohol‐free beverages as a substitute for their alcohol consumption.
