About two thirds of participants (66.2%) were MSMO, and one third (33.8%) were MSMW. More than half of participants (58.1%) identified themselves as “homosexual, gay or same-gender loving,” less than one third (31.6%) identified themselves as “bisexual,” and 7.3% considered themselves “straight.”
presents sample characteristics and comparisons of sociodemographic and social network characteristics between MSMW and MSMO. Less than half of the sample had a college degree (bachelor’s, associate’s, or technical) (42.3%), less than one third were employed full or part time (27.8%), and almost half (44.9%) tested HIV positive or provided documentation of HIV-positive test results. MSMO were significantly more likely to be HIV positive than MSMW (52.3% vs 30.4%). There were no differences in size of total network, network density, number of kin, or number of network members providing emotional or material support. MSMW were older (42 vs 36 years) and less educated. Compared with MSMO, MSMW reported fewer network members with whom they socialized, fewer male network members, and more female network members.
Sample Characteristics and Unadjusted Analysis of African American Men Who Have Sex With Men: Baltimore, Maryland, 2006–2009
Compared with MSMO, MSMW reported more sexual partners, fewer male partners, more exchange partners, and more partners that they always used condoms with. In both groups, the percentage of sexual partners providing material support (14% for MSMO vs 16% for MSMW) or emotional support (15% for MSMO vs 20% for MSMW) was small. MSMW had more sexual partners who provided material support and more sexual partners whom they saw at least once a week, although these differences were not statistically significant.
, , and present the results of multivariate models of differences in participant and network characteristics between MSMW and MSMO. The models examined the social support provided by network members (), sexual partner relationships (), and sexual risk networks as predictors of being MSMW versus being MSMO (). In the model of network social support (), for MSMW there was an independent and statistically significant association with being older, having decreased odds of HIV-positive status, and having attained higher education. MSMW were also associated with greater odds of reporting a higher number of female network members and a lower number of male network members ().

Bivariate and Multivariate Comparisons of Partner Relationships of African American MSMW Versus MSMO: Baltimore, MD, 2006–2009
Bivariate and Multivariate Comparisons of Sexual Risk Networks of African American MSMW Versus MSMO: Baltimore, MD, 2006–2009
In the model of partner relationship (), reporting interacting with a greater number of sexual partners at least once a week was associated with higher odds of being MSMW than of being MSMO. Finally, in the model of risk networks (), reporting more male sexual partners was associated with lower odds of being MSMW than of being MSMO. Reporting concurrent partners, moreexchange partners, and more partners with whom one always used condoms were associated with higher odds of being MSMW than of being MSMO.
