AIDS among the homeless of Boston: a cohort study

We wanted to compare demographics, risk behaviors, AIDS-defining diagnoses, and survival between homeless and housed persons with AIDS in Boston from 1983 to 1991. Our retrospective cohort study used chart review to identify homeless AIDS cases and data from the Massachusetts AIDS Surveillance Program for comparison of homeless and nonhomeless cases. Seventy-two homeless and 1,536 nonhomeless Boston residents were reported to have AIDS between Jan. 1, 1983, and July 1, 1991. Homeless persons with AIDS were more likely to be African American or Latino (81 vs. 39%, p < 0.0001) and have i.v. drug use as a risk behavior (75 vs. 19%, p < 0.0001). The AIDS-defining diagnoses among the homeless were more commonly disseminated Mycobacterium tuberculosis (9 vs. 2%, p < 0.0001) and esophageal candidiasis (17 vs. 9%, p < 0.01). These differences were not seen when the populations were stratified by i.v. drug use. No significant difference in survival between the homeless and nonhomeless cohorts was found. Homeless individuals with human immunodeficiency virus are significantly different than housed persons, and at greater risk of invasive opportunistic infections. Appropriate clinical strategies can be developed to provide needed care to homeless persons with HIV.
