Abstract
In adolescents and young adults, acute consequences like injuries account for a substantial proportion of alcohol-related harm, especially in risky single-occasion (RSO) drinkers. The primary aim of the study was to characterize different drinking profiles in RSO drinkers according to drinking locations and their relationship to negative, alcohol-related consequences. The sample consisted of 2746 young men from the Cohort Study on Substance Use Risk Factors who had reported drinking six or more drinks on a single-occasion at least monthly over the preceding 12 months. Principal component analysis on the frequency and amount of drinking at 11 different locations was conducted, and 2 distinguishable components emerged: a non-party-dimension (loading high on theater/cinema, sport clubs, other clubs/societies, restaurants, and sport events) and a party-dimension (loading high on someone else’s home, pubs/bars, discos/nightclubs, outdoor public places, special events, and home). Differential impacts of drinking location profiles were observed on severe negative alcohol-related consequences (SAC). Relative to those classified as low or intermediate in both dimensions, no significant difference experiencing SAC was found among those who were classified as high in the non-party-dimension only. However, those who were classified as high in the party-dimension alone or in both dimensions were more likely to experience SAC. These differential effects remained after adjusting for alcohol consumption (volume and risky single-occasion drinking), personality traits, and peer-influence [adjusted OR = 0.83 (0.68–1.02), 1.57 (1.27–1.96), and 1.72 (1.23–2.41), respectively], indicating independent effects of drinking location on SAC. The inclusion of sociodemographic factors did not alter this association. The fact that this cluster of party-dimension locations seems to predispose young men to experiencing SAC has important implications for alcohol control policies.
Highlights
From the public health perspective, risky single-occasion drinking (RSOD) is considered one of the major problems stemming from alcohol consumption among adolescents and young adults
According to Knibbe et al [10], exposure to an alcohol-stimulating environment is even more decisive than alcohol-specific beliefs or norms. This might be especially true in a country like Switzerland, where alcohol consumption is integrated into everyday life and where drinking places are multifaceted and likely to influence drinking behavior and its consequences in different ways [1]
CHARACTERIZING DRINKING LOCATION PROFILES To investigate whether drinking locations might cluster in a way as to identify different dimensions of drinking profiles, Principle component analysis (PCA) with varimax rotation was conducted on the frequency and amount of drinking at the 11 different types of location
Summary
From the public health perspective, risky single-occasion drinking (RSOD) is considered one of the major problems stemming from alcohol consumption among adolescents and young adults. Acute consequences like injuries account for a substantial proportion of alcohol-related harm, especially in young people [5,6,7]. According to Knibbe et al [10], exposure to an alcohol-stimulating environment is even more decisive than alcohol-specific beliefs or norms. This might be especially true in a country like Switzerland, where alcohol consumption is integrated into everyday life and where drinking places are multifaceted and likely to influence drinking behavior and its consequences in different ways [1]. Previous results have shown that approximately 80% of alcohol consumption does not take place at home or at someone else’s home, but in public places like bars, discos, and festivals [11]
