This study analyzed factors associated with HIV infection among persons aged >=50 years at HIV diagnosis and examined differences in survival between them and persons aged 13 to 49 years. Methods: HIV-infected persons reported to the Michigan HIV/AIDS registry between January 1990 and October 2000 were analyzed. Results: Of 12,614 eligible persons, 938 (7.4%) were aged >=50 years at HIV diagnosis. Persons aged >=50 years were twice as likely to be male (OR: 1.9)than female. They were slightly at higher risk of contracting HIV through blood products (OR: 1.53) or heterosexual contact (OR: 1.24) than through injection drug use.. Persons aged >=50 years were twice as likely to report unknown HIV risk (OR: 1.8) than injection drug use and they were significantly less likely to be men who have sex with men (OR: 0.64) than injection drug users. The overall mean survival from the date of first positive HIV test until death or October 2000 was 73.5 months (SD:2.21) for persons aged >=50 years and 112.3 months (SD:0.77) for those aged 13 to 49 years (p<0.001). After adjusting for CD4 count at HIV diagnosis (< 200, >=200 cells/ml), survival time remained significantly short among older persons. Conclusions: In Michigan, persons aged >=50 years at HIV diagnosis were likely to have contracted HIV through heterosexual contact, blood products, or injection drug use. HIV infection appeared to have a rapid progression among older persons. See N/A
