The Efficacy of a Relationship-Based HIV/STD Prevention Program for Heterosexual Couples

OBJECTIVES This study examined the efficacy of a relationship-based HIV/sexually transmitted disease prevention program for heterosexual couples and whether it is more effective when delivered to the couple or to the woman alone. METHODS Couples (n = 217) were recruited and randomized to (1) 6 sessions provided to couples together (n = 81), (2) the same intervention provided to the woman alone (n = 73), or (3) a 1-session control condition provided to the woman alone (n = 63). RESULTS The intervention was effective in reducing the proportion of unprotected and increasing the proportion of protected sexual acts. No significant differences in effects were observed between couples receiving the intervention together and those in which the woman received it alone. CONCLUSIONS This study demonstrates the efficacy of a relationship-based prevention program for couples at risk for HIV infection.

Intimate partner violence and HIV risk among urban minority women in primary health care settings

This study describes the associations between intimate partner violence (IPV) and HIV risk among urban, predominantly minority women. Interviews were conducted with 1,590 women, predominantly African American and Latina, attending hospital-based health care clinics. Approximately 1 in 5 women reported experiencing IPV in their current primary heterosexual relationships; about 1 in 8 women reported experiencing IPV in the preceding 6 months. Compared to women who reported no IPV in their primary relationships, women reporting past or current IPV perpetrated by their primary partners were more likely to report having multiple sexual partners, a past or current sexually transmitted infection (STI), inconsistent use or nonuse of condoms, and a partner with known HIV risk factors. These findings indicate that urban minority women experiencing IPV are at elevated risk for HIV infection, results that carry important implications in the efforts to improve HIV and IPV risk assessment protocols and intervention/prevention strategies for women in primary health care settings.

Intimate Partner Violence and HIV Among Drug-Involved Women: Contexts Linking These Two Epidemics—Challenges and Implications for Prevention and Treatment

Intimate partner violence (IPV) and HIV are two serious overlapping public health epidemics that disproportionately affect drug-involved women. This article reviews research that has identified a number of contexts that may explain the links between IPV and HIV transmission risks. These contexts include sexual coercion, fear of violence, negotiation of condom use, extradyadic relationships, disclosure of sexually transmitted infections or HIV seropositivity to intimate partners, drug involvement of women and their male partners, low social status of drug-involved women, relationship dependencies, and sex ratio imbalances. The article focuses on how the bidirectional relationship between IPV and HIV risks may be mediated by a history of childhood sexual abuse and post-traumatic stress disorder. Also addressed are the challenges that substance user treatment programs face in dealing with female clients who experience IPV and the implications for HIV prevention.

Intimate partner violence prevalence and HIV risks among women receiving care in emergency departments: implications for IPV and HIV screening

Objective: To examine (1) the prevalence of experiencing physical, injurious and sexual intimate partner violence (IPV) and (2) the associations between HIV risks and different types of IPV among women receiving care in an inner city emergency department (ED). Methods: A cross-sectional survey that elicited self-reported HIV risks and IPV among a random sample of 799 women receiving ED care. Multiple logistic regression was used to examine the associations between HIV risk and IPV, with covariance adjustment for potentially confounding sociodemographics. Results: 49.6% of the women reported a history of any form (ie, minor and severe type) of physical, injurious and/or sexual IPV, 15% severe sexual coercion (rape) over life time and 11.8% IPV in the past 6 months. Women who reported engaging in sex with a HIV-infected partner or an injecting drug user (IDU), having multiple partners in the past 12 months and injecting drugs were significantly more likely to have experienced any form of physical/injurious IPV, severe physical/injurious IPV and any form of sexual IPV in the past 6 months. In addition, women with multiple partners in the past 12 months and women who reported injecting drugs were significantly more likely to indicate having experienced a severe form of sexual IPV in the past 6 months. Conclusion: For many women receiving care in EDs, IPV and several HIV risk behaviours are frequent, co-occurring health problems. HIV testing and routine IPV inquiry in ED settings offer an important opportunity to identify women who are affected by these overlapping epidemics and refer them to appropriate treatment services.

Couple-based HIV prevention for low-income drug users from New York City: a randomized controlled trial to reduce dual risks.

Objective: Dual threats of injection drug use and risky sexual practices continue to increase transmission of HIV and other sexually transmitted Infections (STIs) among drug-using couples in low-income communities in the United States. Two hypotheses were tested: (1) “intervention effect”—whether the HIV risk-reduction intervention provided to the couple or individual partners would be more efficacious in decreasing number of unprotected sexual acts and having a lower cumulative incidence of biologically confirmed STIs over the 12-month follow-up period compared with the attention control condition; and (2) “modality effect”—whether the HIV risk-reduction intervention would be more likely to decrease the number of unprotected sexual acts and have a lower cumulative STI incidence when delivered to a couple compared with the same intervention delivered to an individual. Design: Using a randomized controlled trial, 282 HIV-negative drug-using couples (564 individuals) were randomly assigned to receive either of the following: (1) couple-based risk reduction; (2) individual-based HIV risk reduction, or (3) couple-based wellness promotion, which served as an attention control condition. Results: Over 12-month follow-up, there was a 30% reduction in the incidence rate of unprotected acts of intercourse with the study partners compared with participants in the attention control arm. Moreover, over 12-month follow-up there was a 29% reduction in the same outcome in the couple arm compared with the individual arm with a 41% reduction at the 12-month follow-up. Conclusion: A couple-based approach that addresses drug and sexual risks and targets low-income active drug users may help curb the HIV epidemic.

Sexual risk behaviors alcohol abuse and intimate partner violence among sex workers in Mongolia: implications for HIV prevention intervention development.

This study examines HIV/STI risk behaviors, alcohol abuse, intimate partner violence, and psychological distress among 48 female sex workers in Mongolia to inform the design of a gender-specific, HIV/STI prevention intervention for this population. Quantitative findings demonstrate that over 85% of women reported drinking alcohol at harmful levels; 70% reported using condoms inconsistently with any sexual partner; 83% reported using alcohol before engaging in sex with paying partners; and 38% reported high levels of depression. Focus group findings provide contextual support and narrative descriptions for the ways that poverty, alcohol abuse, interpersonal violence, and cultural norms that stigmatize and marginalize women are intertwined risk factors for STIs, including HIV, among these vulnerable women.

Perpetration of Intimate Partner Violence Among Men in Methadone Treatment Programs in New York City

This study examined the prevalence of perpetration of intimate partner violence among 356 men recruited from methadone maintenance treatment programs. We used logistic regression with covariance adjustment to examine the associations between intimate partner violence and illicit drug use by the participants, their female partners, or both. We found a high prevalence of intimate partner violence among the men in our sample. Significant associations between intimate partner violence and illicit drug use varied by types of drugs and whether the female partner or both partners were using drugs.

Promoting female condom use to heterosexual couples: findings from a randomized clinical trial.

CONTEXT The female condom remains the only female-initiated method for preventing pregnancy and STDs, including HIV. Innovative methods for promoting its use, and for involving male partners in its use, are needed. METHODS A sample of 217 women and their main male sexual partners were randomly assigned to one of three study conditions: a six-session relationship-based STD prevention intervention provided to the couple together, the same intervention provided to the woman only or a single-session education control provided to the woman only. Assessments were conducted at baseline and three months postintervention. Contrast coding was used to examine whether the effects of the two active interventions differed from those of the control intervention, and whether the effects of the two active interventions differed from each other. Regression analyses were used to estimate treatment effects. RESULTS During follow-up, participants in either active intervention were more likely to use a female condom with their study partner and with all partners, and used female condoms at a higher rate with all partners, than individuals assigned to the control intervention; at the end of three months, they were more likely to intend to use the condom in the next 90 days. No significant differences in outcomes were found between the active intervention groups. CONCLUSIONS Focusing on both a woman and her main male sexual partner is efficacious in increasing female condom use and intention to use among heterosexual couples at risk for HIV and other STDs.

Posttraumatic Stress Disorder and HIV Risk Among Poor, Inner-City Women Receiving Care in an Emergency Department

OBJECTIVES We examined the associations between posttraumatic stress disorder (PTSD) and HIV risk behaviors among a random sample of 241 low-income women receiving care in an urban emergency department. METHODS We recruited participants from the emergency department waiting room during randomly selected 6-hour blocks of time. Multivariate analyses and propensity score weighting were used to examine the associations between PTSD and HIV risk after adjustment for potentially confounding sociodemographic variables, substance use, childhood sexual abuse, and intimate partner violence. RESULTS A large majority of the sample self-identified as Latina (49%) or African American (44%). Almost one third (29%) of the participants met PTSD criteria. Women who exhibited symptoms in 1 or more PTSD symptom clusters were more likely than women who did not to report having had sex with multiple sexual partners, having had sex with a risky partner, and having experienced partner violence related to condom use in the preceding 6 months. CONCLUSIONS The high rate of PTSD found in this sample and the significant associations between PTSD symptom clusters and partner-related risk behaviors highlight the need to take PTSD into account when designing HIV prevention interventions for low-income, urban women.

Efficacy of a Savings-Led Microfinance Intervention to Reduce Sexual Risk for HIV Among Women Engaged in Sex Work: A Randomized Clinical Trial

OBJECTIVES We tested whether a structural intervention combining savings-led microfinance and HIV prevention components would achieve enhanced reductions in sexual risk among women engaging in street-based sex work in Ulaanbaatar, Mongolia, compared with an HIV prevention intervention alone. METHODS Between November 2011 and August 2012, we randomized 107 eligible women who completed baseline assessments to either a 4-session HIV sexual risk reduction intervention (HIVSRR) alone (n=50) or a 34-session HIVSRR plus a savings-led microfinance intervention (n=57). At 3- and 6-month follow-up assessments, participants reported unprotected acts of vaginal intercourse with paying partners and number of paying partners with whom they engaged in sexual intercourse in the previous 90 days. Using Poisson and zero-inflated Poisson model regressions, we examined the effects of assignment to treatment versus control condition on outcomes. RESULTS At 6-month follow-up, the HIVSRR plus microfinance participants reported significantly fewer paying sexual partners and were more likely to report zero unprotected vaginal sex acts with paying sexual partners. CONCLUSIONS Findings advance the HIV prevention repertoire for women, demonstrating that risk reduction may be achieved through a structural intervention that relies on asset building, including savings, and alternatives to income from sex work.
