Alcoholism among homeless men in Munich, Germany.

Probably in association with changes in the economic structure and high unemployment rates in western industrialized countries, homelessness is becoming more apparent publicly and receiving increased media attention. More studies on the issue of mental illness and homelessness have been performed in recent years in North America while hardly any representative and reliable data exists concerning Germany and some other European countries. The aim of our study was 1) to assess alcohol abuse and dependency as well as other mental disorders in a representative sample of homeless men in Munich using reliable methods of case identification (Diagnostic Interview Schedule [DIS and DIS/DSM-III diagnoses); 2) to compare homeless alcoholics with homeless non-alcoholics in our sample on relevant variables and issues and 3) to compare our data from the sample of homeless men in Munich with data obtained by others using the same case identification procedure (DIS/DSM-III diagnoses). According to our results, the lifetime prevalence of any DIS/DSM-III Axis I diagnoses was 94.5% and the lifetime prevalence of substance use disorder was 91.8%. The single most prevalent diagnosis among homeless males in Munich was alcohol dependency (lifetime 82.9%), while alcohol abuse (lifetime 8.2%) and drug abuse/dependency were considerably lower (lifetime 17.8%). Data show that alcoholism and its consequences were more severe in the Munich as compared to the Los Angeles homeless sample. Homeless alcoholics showed a high comorbidity with other mental disorders (lifetime) such as affective disorders (44.4%), anxiety disorders (22.6%), drug abuse/dependence (18.8%) and schizophrenia (12.0%); 64% of those with alcoholism at some time during their life had at least one other lifetime mental disorder. Alcohol-related patterns of living and symptoms as well as social or role functioning are described for homeless alcoholics in Munich and compared with data from other relevant studies. Considering the extremely high prevalence of alcohol dependence frequently in combination with other mental disorders, the use of alcohol rehabilitation and other services as well as self-help groups was minimum among Munich homeless alcoholics. New concepts to deal with these problems are needed and if they exist, they need to be implemented.
