Objective: To review the physical and mental status in homeless people.
Data sources: A MEDLINE database search covering 5 decades was supplemented by tracing back through references from existing review work. Over 200 articles were extracted, and 106 were selected for review.
Main findings: Homeless persons suffer frequently from physical health problems like tuberculosis, asthma, bronchitis, HIV infection, and as a consequence, they run an increased risk for premature mortality. The prevalence of mental disorders among homeless individuals varies from 80-95% in the USA, Australia, Canada, Norway, and Germany to 25-33% in Ireland and Spain. The most prominent mental disorders among the homeless, which vary from country to country, are depression, affective disorders, substance abuse, psychotic disorders, schizophrenia, and personality disorders.
Conclusion: Homelessness is a major public health problem that should have our special interest.
