Consistent condom use among high risk groups such as female sex workers (FSWs) remains low. Adolescent female sex workers are especially at higher risk for HIV/STI infections. However, few published studies have compared the sexual risk negotiations among adolescent, emerging adult, and older age groups or the extent a manager's advice about condom use is associated with an FSW's age. Of 1,388 female bar/spa workers surveyed in the southern Philippines, 791 FSW who traded sex in the past 6 months were included in multivariable logistic regression models. The oldest FSWs (aged 36-48) compared to adolescent FSWs (aged 14-17) were 3.3 times more likely to negotiate condoms when clients refused condom use. However, adolescent FSWs received more advice from their managers to convince clients to use condoms or else to refuse sex, compared to older FSWs. Both adolescent and the oldest FSWs had elevated sexually transmitted infections (STIs) and inconsistent condom use compared to other groups. Having a condom rule at the establishment was positively associated with condom negotiation. Factors such as age, the advice managers give to their workers, and the influence of a condom use rule at the establishment need to be considered when delivering HIV/STI prevention interventions.

Background/purpose

Taiwan experienced a rapid surge in human immunodeficiency virus (HIV) among injection drug users (IDUs) from 2003 to 2005. The male-to-female ratio of HIV cases decreased from 20:1 in 2003 to 6:1 in 2006. This change is primarily due to increasing numbers of female injection drug users in Taiwan. Our primary objective was to identify the risk factors associated with HIV infection among incarcerated female drug users.

Methods

A case-control design involved recruitment of all eligible HIV-infected female inmates from all 24 prisons in Taiwan from November to December, 2007. Eligible HIV seronegative controls were chosen within the same prison and matched to the cases by age (within 3 years) and by history of illicit drug use. A subsample of these matches was randomly selected since there were many more eligible controls than HIV-infected cases. An anonymous self-administered questionnaire was completed with assistance from trained research assistants.

Results

A total of 114 cases and 149 control participants were recruited, with a response rate of 82% and 54%. Injectable heroin use was significantly greater (p = 0.02) among HIV-infected cases (93.0%) than un-infected controls (84.6%). Compared to seronegative controls, HIV-infected cases were more likely to share drug paraphernalia and have drug-using sexual partners. Multiple logistic regression analysis revealed that the number of imprisonments (between 2-5 times; OR = 5.23), sharing mainly dilutes (OR= 63.47), and sharing dilutes concurrently with needles (OR= 127.33) significantly predicted HIV seroconversion, after controlling for age and years of education.

Conclusion

Sharing needles/dilutes and practicing unsafe intercourse with drug-using sexual partners places female drug users at considerable risk.

States across the U.S. lack effective ways to quantify HIV prevalence rates among men who have sex with men (MSM). We estimated population-based HIV prevalence rates among MSM in the 17 southern states by race/ethnicity. Through 2007, estimated HIV prevalence rates per 100,000 MSM ranged from 2,607.6 among white (non-Hispanic) MSM in Maryland to 41,512.9 among black (non-Hispanic) MSM in the District of Columbia. Black MSM rates significantly exceeded Hispanic and white MSM rates in each state. Significant racial/ethnic disparities in rates persisted in a sensitivity analysis examining the possibility that minority MSM populations had been underestimated in each state. Compared with black, Hispanic, and white non-MSM males, respectively, rates at the regional level were 25.2 times higher for black MSM, 43.0 times higher for Hispanic MSM, and 106.0 times higher for white MSM. State-level analysis of racial/ethnic-specific MSM HIV prevalence rates can help guide resource allocation and assist advocacy.

Background/objectives

HIV continues to be a significant problem among substance users and their sexual partners in the United States. The National Drug Abuse Treatment Clinical Trials Network (CTN) offers a national platform for effectiveness trials of HIV interventions in community substance abuse treatment programs. This article presents the HIV activities of the CTN during its first 10 years.

Results

While emphasizing CTN HIV protocols, this article reviews the (1) HIV context for this work; (2) the collaborative process among providers, researchers, and National Institute on Drug Abuse CTN staff, on which CTN HIV work was based; (3) results of CTN HIV protocols and HIV secondary analyses in CTN non-HIV protocols; and (4) implications for future HIV intervention effectiveness research in community substance abuse treatment programs.

Conclusion/significance

While the feasibility of engaging frontline providers in this research is highlighted, the limitations of small to medium effect sizes and weak adoption and sustainability in everyday practice are also discussed.
