Breath alcohol concentration, hazardous drinking and preloading among Swedish university students.

BACKGROUND

Approximately half of all young adults in Sweden are university students, and alcohol consumption is often a central part of students' social lives. Heavy drinking is associated with negative consequences, such as poor study skills, sexual risk-taking, violence and accidents. The aim of the present study is to assess the levels of alcohol intoxication as well as hazardous alcohol use among students at Swedish universities.

METHODS

In an alcohol field study, students (≥18 years old) were randomly selected and invited to participate. The settings were eight different parties at four universities in Sweden. Alcohol intoxication was measured using a breath analyser for breath alcohol concentration (BrAC). Demographic data (i.e., sex, age, number of years at the university) and responses to the Alcohol Use Disorders Identification Test-Consumption (AUDIT-C) were gathered through face-to-face interviews for the assessment of hazardous alcohol use.

RESULTS

In total, 723 students were invited to participate, 605 of whom consented (84% response rate). The mean age of the respondents was 22.2 years, and the proportion of women was 37%. A majority of the respondents (91%) reported drinking before arriving at the parties. Among those who had consumed alcohol before arriving, the average BrAC was 0.086%, and 36% had BrACs of 0.100% or more. The proportion of students reporting hazardous use was 86% for women and 87% for men.

CONCLUSIONS

This study provides the actual levels of intoxication among university students in four different cities. Alcohol intoxication and hazardous use among Swedish university students is a concern, and the university setting is an important arena for implementation of alcohol prevention strategies.
