Availability of different types of alcohol and amount of intake and next-day hangover – a naturalistic randomized controlled pilot trial

Abstract

Purpose The authors tested the hypothesis that having a high availability of different types of alcoholic drinks (beer, wine or spirits) as compared to being confined to one type only associate with a higher alcohol intake and worse next-day hangover. Design/methodology/approach This randomized controlled pilot trial took place over one evening and included 35 individuals randomized into two groups. Individuals in the mixed-type group could consume any type of alcoholic drink (beer, wine, cocktails), whereas individuals in the single-type group were to adhere to one type of own choice. Information on number of drinks was obtained continuously during the trial. Hangover symptoms were reported by participants using the Acute Hangover Severity Scale (AHSS) at 8:00, 12:00 and 16:30 the following day. Median regression was used to assess number of drinks and maximum AHSS in two groups. Findings Participants in the mixed-type group consumed significantly more drinks compared to the single-type group (10.9 vs 5.7, p < 0.001). The maximal AHSS score the day after drinking was higher in the mixed-type group as compared to the single-type group (median 4.3 vs 2.6, p < 0.0001). Originality/value This study suggests that having a variety of alcoholic drinks available associates to a higher alcohol intake and more severe hangover as compared to having to adhere to one type only. Larger studies are warranted to validate findings.
