Participation of MSM in group sex events (GSEs) is an understudied phenomenon. Studies on GSEs identified significant proportions of MSM engaging in unprotected anal intercourse (UAI). We sought to identify the prevalence of group sex participation among MSM in Washington, DC and to characterize these experiences. Data were collected for NHBS-MSM-3 in 2011. More than one-quarter of MSM (27.2 %) reported engaging in group sex in the prior year, with one-third reporting no condom use with their sex partners (33.0 %). In multivariable logistic regression, men who participated in a GSE in the prior year were significantly younger, more likely to be white, and to have used crystal meth, poppers, and downers in the past year. The high prevalence of UAI during GSEs, especially in view of the fact that HIV-positive MSM were significantly less likely to report condom use, offers an opportunity to develop risk reduction interventions specific to GSE attendees.

Social norms around condom use and safe sex as well as HIV/AIDS stigma are used to identify persons at higher risk for HIV. These measures have been developed and tested in a variety of settings and populations. While efforts have been undertaken to develop context specific measures of these domains among Chinese MSM, the feasibility of using existing measures is unknown. A survey of MSM, based on respondent-driven sampling, was conducted in Beijing. Existing measures of condom social norms, attitudes towards safer sex and HIV/AIDS stigma were piloted. Internal consistency of all measures was high. As expected higher levels of condom social norms and positive attitudes towards safer sex were associated with condom use. HIV/AIDS stigma and discrimination had a significant relationship with never having an HIV test and lack of discussion of HIV/AIDS with male partners. Correlates of low condom social norms were age, education, employment and resident status. Existing measures of condom social norms, attitudes towards safer sex and HIV/AIDS stigma appear to be appropriate for use among Chinese MSM. Using existing measures as opposed to developing new measures has the potential to expedite investigations into psychosocial correlates of HIV risk behavior. [ABSTRACT FROM AUTHOR]

The epidemiology of HIV in urban centers of the United States such as the District of Columbia (DC) is dynamic with rates of new HIV and AIDS diagnoses as well as risk factors elevated. Correlates of HIV among heterosexual women extend beyond traditional, individual risk factors to structural factors. The purpose of this study was to compare proportions of HIV and correlates of HIV among women participating in National HIV behavioral surveillance (NHBS) system in 2006-7 (NHBS Cycle 1) and 2010 (NHBS Cycle 2). Analysis of 677 female participants at elevated risk for HIV revealed high prevalence of individual-level HIV-associated risk factors (e.g., sexual behavior) and socio-structural associated risk factors (e.g., homelessness, incarceration, lack of health insurance). While a greater proportion of women were HIV-infected in Cycle 2, after controlling for the distribution of demographic characteristics to adjust for a change in eligibility criteria, the pooled sample did not reveal a significantly increased proportion of HIV-infected women in Cycle 2. Homelessness and condom use were associated with greater relative odds of HIV after adjustment for confounders, and non-injection drug use was associated with reduced odds. Findings inform our understanding of the continuing HIV epidemic in DC and support development of effective interventions to slow the epidemic among women in DC and similar urban centers.

The District of Columbia launched a routine HIV testing initiative in 2006. We examined HIV testing behaviors among heterosexuals at risk for HIV over time using CDC National HIV Behavioral Surveillance data from Washington, DC for the heterosexual cycles from 2006 to 2007 (Cycle 1) and 2010 (Cycle 2). Past year and past 2-year HIV testing across study cycles were compared using Chi square tests. Weighted multivariable logistic regression identified correlates of past year testing. The majority of participants across both cycles were black and female. Cycle 1 participants were significantly more likely to have ≥4 partners in the past year, casual sex partners, and have anal sex at last sexual encounter ( p < 0.05). Lifetime testing was high, and individuals from Cycle 2 versus Cycle 1 were more likely to have been tested in the past 2 years. There were no significant differences in past year testing or being offered the HIV test at last health care visit by cycle. Independent correlates of past year testing were seeing a health care provider in the past year and using condoms at last vaginal sex. In conclusion, although past year testing did not differ between the two data collection years, the proportion of heterosexuals testing in the past 2 years was higher in Cycle 2 versus Cycle 1, suggesting successful expansion of HIV testing between the two time periods.

To investigate factors associated with online sex-seeking behaviors among men who have sex with men (MSM) in Beijing, China. MSM participants were recruited from two cohort studies with multiple enrollment methods from November 2006 to February 2007 and from March to June 2008, respectively. Data collected included demographics and sexual behaviors. Of the 901 participants, 68.1% were single; 69.3% were non-Beijing residents; 94.4% considered themselves to be homosexual; 65.2% received college or higher levels of education; the median age was 26 years; 73.0% sought male sex partners via the Internet in the past 3 months; 66.2% had ≥2 sex partners. Younger age, higher levels of education and having had ≥2 male sex partners in the past 3 months were independently associated with seeking sex partners on the Internet. These findings indicate that Internet-based intervention programs could encourage younger high-risk MSM to use condoms and reduce their numbers of sexual partners. [ABSTRACT FROM AUTHOR]

A retrospective economic evaluation of a female condom distribution and education program in Washington, DC. was conducted. Standard methods of cost, threshold and cost-utility analysis were utilized as recommended by the U.S. Panel on cost-effectiveness in health and medicine. The overall cost of the program that distributed 200,000 female condoms and provided educational services was $414,186 (at a total gross cost per condom used during sex of $3.19, including educational services). The number of HIV infections that would have to be averted in order for the program to be cost-saving was 1.13 in the societal perspective and 1.50 in the public sector payor perspective. The cost-effectiveness threshold of HIV infections to be averted was 0.46. Overall, mathematical modeling analyses estimated that the intervention averted approximately 23 HIV infections (even with the uncertainty inherent in this estimate, this value appears to well exceed the necessary thresholds), and the intervention resulted in a substantial net cost savings.
