title: Heavy episodic drinking and alcohol-related injuries: An open cohort study among college students.
abstract: OBJECTIVE
  The objective of this study is to assess the effects of Heavy Episodic Drinking (HED) on the incidence of alcohol-related injuries among university students in Spain, taking sex into consideration.
  
  
  METHODS
  We carried out an open cohort study among college students in Spain (992 women and 371 men). HED and alcohol-related injuries were measured by question 3rd and 9th of Alcohol Use Disorders Identification Test to every participant at the ages of 18, 20, 22, 24 and 27. For data analysis we used a Multilevel Logistic Regression for repeated measures adjusting for alcohol and cannabis use.
  
  
  RESULTS
  The incidence rate of alcohol-related injuries was 0.028year-1for females and 0.036year-1for males. The multivariate analysis showed that among females a high frequency of HED and use of cannabis are risk factors for alcohol-related injuries (Odds Ratio [OR]=2.64 and OR=3.68), while being more than 23 is a protective factor (OR=0.34). For males, bivariate analysis also showed HED like risk factor (OR=4.69 and OR=2.51). Finally, the population attributable fraction for HED among females was 37.12%.
  
  
  CONCLUSIONS
  HED leads to an increase of alcohol-related injuries in both sexes and being over 23 years old acts as a protective factor among women. Our results suggest that about one third of alcohol-related injuries among women could be avoided by removing HED.
