title: HIV diagnoses among men who have sex with men and women-United States and 6 dependent areas, 2008-2011.
abstract: OBJECTIVE
  We sought to describe HIV diagnoses among men who have sex with men and women (MSMW), who have the potential to bridge HIV transmission risk from men who have sex with men (MSM) to women.
  
  
  METHODS
  Applying National HIV Surveillance System data for persons aged 13 years and older, we examined estimated numbers and percentages of HIV diagnoses among MSMW and MSM only (MSMO) from 2008 to 2011, and estimated the annual percentage change and 95% confidence intervals, by age and race/ethnicity.
  
  
  RESULTS
  In 2011, 26.4% of 30,896 MSM diagnosed with HIV infection also had had sex with women. A larger percentage of MSMW were Black/African American (44.5%) compared with MSMO (36.0%), and fewer MSMW were White (26.4%) compared with MSMO (36.2%); similar percentages were classified as either MWMW or MSMO among other racial/ethnic groups. Among MSMW, HIV diagnoses were relatively stable and MSMO increased more than 6% annually among those aged 13 to 29 years.
  
  
  CONCLUSIONS
  Many MSM diagnosed with HIV infection had also had sex with women. Intensified interventions are needed to decrease HIV infections overall for MSMW and reverse the increasing trends among young MSMO.
