Dr Tamlin Conner and Dr Damian Scarf report in the Journal of Studies on Alcohol and Drugs that they found high drinking rates during orientation week predicted increased rates of drinking during the academic year, especially for men.
" ...when we controlled for pre-university drinking, men who drank more during orientation week showed significantly higher rates of drinking during the academic year - more than what would be expected based on their pre-university drinking rates."
Those who drank at low rates before university but who drank heavily during orientation week were nearly equivalent in their academic year drinking to those who drank heavily both before and during orientation.
The pattern for women was the same, but not statistically significant possibly because of having only a small number of female participants. Dr Conner said more research was needed to confirm the link between between heavy drinking during orientation and later.
"If this is shown to be the case, orientation week may be a prime target for alcohol-based interventions in universities," she said.
In their paper, the authors wrote: "Students viewing orientation week as a 'one-off' event or a last blow-out before the real work begins should consider the impact their drinking may have on their academic year."
