Objectives:
The aim of this study was to identify risk factors and estimate prevalence of depressive episodes among Wroclaw’s universities students.

Methods:
Polish adaptation of the Composite International Diagnostic Interview (CIDI) was implemented to gather epidemiological data from 370 students of public universities in Wroclaw. Proportional stratified sampling was performed to obtain distinct, independent strata representing sex, year of study and educational profiles. Randomisation was ensured by recruitment procedures.

Results:
Prevalence of depressive episodes among students in Wroclaw is high – 14.7% throughout life, 9.8% within 12 months prior to the interview. High prevalence of severe and moderate depressive episodes seems to be worrisome (respectively 5.1% and 6.6% throughout life, 3.8% and 3.9% within 12 months prior to the study). Year of study, profile and lack of partner relationship remain risk factor for depression.

Conclusions:
High prevalence of depressive episodes indicates the need for prevention and therapy based on epidemiological data and tailored to the students’ needs. Depression among students requires further epidemiological studies.
