Unit for Health Promotion Research Background The relationship between problematic alcohol consumption and academic performance is a key concern on university and college campuses. Alcohol consumption has been negatively associated with academic performance. Only few studies have used objective measures of academic performance. Few authors have analysed whether frequency of drinking or amount of alcohol is more important in predicting academic performance.
Unit for Health Promotion Research This study examined the associations between three academic achievement variables and three alcohol consumption variables (frequency of alcohol consumption, heavy episodic drinking, and problem drinking). Which of the measures of alcohol consumption is most influential? Which academic outcome is mostly affected by alcohol drinking? Aims
Unit for Health Promotion Research Methods Data collection n Cross-sectional study among 380 university students at the University of Gloucestershire who completed a general health questionnaire. Their module grades were retrieved from the university computer systems Alcohol drinking n Frequency of alcohol consumption in the past three months n Heavy episodic drinking (had 5 drinks in a row) in the past 30 days n Problem drinking (CAGE score) Educational achievement n Students reflection on their academic achievement (importance of achieving good grades) n Students subjective comparative appraisal of their overall academic attainment (academic performance in comparison with their peers) n Actual module mark

Unit for Health Promotion Research Results We found relatively strong negative associations between heavy episodic drinking and subjective measures of academic achievement (importance of good grades, academic performance relative to peers). The other two measures of alcohol drinking (frequency of alcohol consumption and problem drinking) showed fewer associations with academic outcomes than heavy episodic drinking. While alcohol drinking was related to impairments in subjectively reported academic achievement, we failed to find associations with objectively measured module marks.
Unit for Health Promotion Research Limitations Sample size Module mark may not reflect average grades Selection bias (no data on students not attending classes) Under-reporting of drinking, while over-reporting of academic performance No causal relationships Many other (unmeasured) factors might interfere
Unit for Health Promotion Research Academic achievement at university Academic achievement at high school Early alcohol use Heavy alcohol use Other impairments Sleep Socio-emotional problems Etc. Other factors
Unit for Health Promotion Research Conclusions Alcohol misuse, especially heavy episodic drinking is very likely to have negative consequences on academic performance. Alcohol policies on campus and educational and normative campaigns for students are highly relevant. Future research should include prospective designs as well as objective and subjective measures for academic performance.
