Binge drinking is associated with reduced quality of life in young students: A pan-European study.

Background: Binge drinking (BD) is frequently observed in youth, with psychological and cognitive consequences, but its link with quality of life has been scarcely explored.
Methods: Sociodemographic and alcohol consumption characteristics were collected in a cross-sectional survey including 15,020 European students. Health-related quality of life was assessed using the Alcohol Quality of Life Scale (AQoLS) measuring the self-reported negative impact of alcohol consumption. A flexible link function, using Bayesian P-splines, was used to study the relationship between alcohol-related quality of life and alcohol consumption.
Results: A non-linear relationship between BD and AQoLS scores was identified, showing that: (1) For students presenting moderate BD pattern, alcohol consumption is related to a robust reduction in quality of life, this link remaining stable for students with more intense BD patterns; (2) BD are not strongly associated with social, personal, and work activities, but are linked to an increase in perceived loss of control over consumption; (3) Harmful or hazardous consumption is also related with a massive decrease in quality of life; (4) The strongest relationship between BD and impacted quality of life is found among males and Eastern European students.
Conclusions: These results demonstrate the importance of measuring the perceived relation between alcohol and quality of life, beyond the classically assessed consequences, as this relation is strong among young students. Prevention programs should take this into account, notably regarding the perceived loss of control over alcohol consumption, which constitutes a key factor for the emergence of severe alcohol-use disorders.
