title: A systematic review of studies of depression prevalence in university students.
abstract: BACKGROUND
  Depression is a common health problem, ranking third after cardiac and respiratory diseases as a major cause of disability. There is evidence to suggest that university students are at higher risk of depression, despite being a socially advantaged population, but the reported rates have shown wide variability across settings.
  
  
  OBJECTIVE
  To explore the prevalence of depression in university students.
  
  
  METHODS
  PubMed, PsycINFO, BioMed Central and Medline were searched to identify studies published between 1990 and 2010 reporting on depression prevalence among university students. Searches used a combination of the terms depression, depressive symptoms, depressive disorders, prevalence, university students, college students, undergraduate students, adolescents and/or young adults. Studies were evaluated with a quality rating.
  
  
  RESULTS
  Twenty-four articles were identified that met the inclusion and exclusion criteria. Reported prevalence rates ranged from 10% to 85% with a weighted mean prevalence of 30.6%.
  
  
  CONCLUSIONS
  The results suggest that university students experience rates of depression that are substantially higher than those found in the general population. Study quality has not improved since 1990.
