Nationally heterosexuals are
an HIV prevention priority. In addition to case based HIV surveillance,
behavioral surveillance surveys are conducted among heterosexuals living in
high AIDS morbidity neighborhoods.
We report on risk behaviors and HIV prevalence
among "high-risk" heterosexuals in San Francisco. National HIV
Behavioral Surveillance System is coordinated by the CDC and implemented in 21
health jurisdictions. The studies were conducted in 2006, 2010 and 2013 in San
Francisco. Respondent driven sampling was used to sample participants. Eligible
persons were 18-50 years old and had sex with at least one opposite gender
partner in the past year. We obtained samples of 371, 421, 165 heterosexuals in
2007, 2010 and 2013, respectively. Some demographics varied across the
3 years.
Residential neighborhoods changed, homelessness and healthcare
coverage increased. Binge drinking, cocaine and heroin use increased while
methamphetamine use declined. There were no changes in numbers of partners,
unprotected vaginal intercourse or unprotected anal intercourse. Commercial sex
work increased.
Even with "fine tuning" of eligibility criteria to
attempt to find heterosexual HIV cases, we estimate that HIV prevalence was
0.3, 0.2 and 2.4 % in 2007, 2010 and 2013 respectively. The increase was
not statistically significant.
For the present, effective prevention among
persons in the populations most severely affected by HIV remains the priority,
for their own benefit and to prevent transmission to other vulnerable populations
to which they may be connected.
