MOURE-RODRIGUEZ, Lucía et al. Heavy drinking and alcohol-related injuries in college students. Gac Sanit [online]. 2014, vol.28, n.5, pp.376-380. ISSN 0213-9111.

Objective: The main objective of this study is to evaluate the effect of heavy drinking on alcohol-related injuries. Material and methods: We carried out an open cohort study among university students in Spain (n = 1,382). Heavy drinking and alcohol-related injuries were measured by administrating AUDIT questionnaires to every participant at the ages of 18, 20, 22 and 24. For data analysis we used a Multilevel Logistic Regression for repeated measures adjusting for consumption of alcohol and cannabis. Results: The response rate at the beginning of the study was 99.6% (1,369 students). The incidence rate of alcohol-related injuries was 3.2 per 100 students year. After adjusting for alcohol consumption and cannabis use, the multivariate model revealed that a high frequency of heavy drinking was a risk factor for alcohol-related injuries (Odds Ratio = 3.89 [95%CI: 2.16 - 6.99]). The proportion of alcohol-related injuries in exposed subjects attributable to heavy drinking was 59.78% [95%CI: 32.75 - 75.94] while the population attributable fraction was 45.48% [95%CI: 24.91 - 57.77]. Conclusion: We can conclude that heavy drinking leads to an increase of alcohol-related injuries. This shows a new dimension on the consequences of this public concern already related with a variety of health and social problems. Furthermore, our results allow us to suggest that about half of alcohol-related injuries could be avoided by removing this consumption pattern.
