Objectives:
We addressed gaps in current HIV prevention research by examining the differences between 2 groups of young men: men who have sex with men only (MSM/O) and men who have sex with men and women (MSM/W). We examined patterns and correlates of sexual risk, and considered how race/ethnicity may affect these relationships.
Methods:
Cross-sectional self-report data were collected from a racially diverse sample of 10,295 young MSM from 1999 to 2002. The sample comprised data from 13 urban locations across the US.
Results:
MSM/W reported less unprotected anal intercourse (UAI) than MSM/O, despite reporting less exposure to HIV prevention interventions, lower social support, and less awareness of antiretroviral therapies. African American men were more likely to be MSM/W and less likely to report UAI. Ever getting an HIV test was associated with less UAI only among African American participants (MSM/W or MSM/O) in racial/ethnic group-specific analyses.
Conclusions:
HIV prevention interventions for MSM should address differences between MSM/W and MSM/O. An important component of HIV prevention efforts designed for African American MSM/W and MSM/O should be HIV testing.

Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.

Factors Affecting the Risk of Infection
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin create...
