This article summarizes physical health, mental health, and substance
abuse problems of users of four of Detroit's largest homeless shelters
. Shelter users with mental illness or substance abuse problems were c
ompared with those without these problems. Alcohol abusers were signif
icantly more likely to have low blood pressure, symptoms of liver dise
ase, and a tuberculosis treatment history. No health differences were
found for those with or without a history of psychiatric hospitalizati
on, Contrary to expectations, few gender differences were found. Aside
from the obvious need for low-income housing, comprehensive and integ
rated treatment approaches from health care, mental health, and substa
nce abuse agencies are needed to help homeless individuals. Social wor
kers need to become more directly involved in service and policy issue
s for this vulnerable population.
