Swedish Exchange students’ alcohol use, drug use, risky sexual behaviour, mental health, and self-rated health: a follow-up study

Results: We found a statistically significant proportional increase in weekly consumption of alcohol among exchange students after their semester abroad. A larger proportion exchange student had sex with a new partner and sex with more than three partners during the last six months compared to follow-up campus students. Conclusions: Our findings indicate that prospective exchange students consume higher amounts of alcohol, which was increased further during their semester abroad, and indulge in sexually risky behaviour to a higher degree than campus students.

Exchange students increased use of alcohol and sexually risky behaviour could be associated with even greater risks due to them being in an unknown environment, unfamiliar culture and with limited support from family and friends. This highlights the need for further research on exchange students’ experiences, especially concerning alcohol use and sex while abroad.
