Transmission of STIs/HIV at the partnership level: beyond individual-level analyses

Associations between externalizing behavior problems and risky sexual behaviors in adolescence: Attachment as a mediator

INTRODUCTION

Risky sexual behaviors in adolescence are associated with negative health and psychological functioning outcomes. Although the association between behavior problems and risky sexual behaviors is well established, addressing these problems requires understanding the mechanisms that help explain this association. Adolescent attachment, while related to risky sexual behavior, has not been extensively explored as an outcome of childhood externalizing problems. The two objectives of this study were to explore the links between parental and peer attachment and risky sexual behaviors and to examine the mediating effect of attachment on the links between behavior problems and risky sexual behaviors.

METHODS

Five hundred and ninety-eight French-Canadian adolescents (46.2% girls), Mage at T1 = 13.23; Mage at T2 = 14.28; Mage at T3 = 17.35) participated in this longitudinal study.

RESULTS

The quality of parental attachment at T2 was significantly and negatively associated with risky sexual behaviors 3 years later, at T3. More specifically, a lower quality parental attachment relationship was associated with having nonexclusive partners as well as with inconsistent condom use. Finally, parental attachment (T2) was a significant mediator between behavior problems (T1) and risky sexual behaviors (T3), but only for younger adolescents.

CONCLUSIONS

Findings suggest that in addition to behavior problems in adolescence, the quality of parental attachment relationships may help in understanding risky sexual behaviors in adolescence.

Behavioral aspects and the transmission of Monkeypox: A novel approach to determine the probability of transmission for sexually transmissible diseases

Motivated by the 2022 worldwide Monkeypox (MPox) outbreak, a compartmental model is proposed to predict the evolution of the disease. Numerous models have been proposed for infectious diseases so far, although the number of variables makes it difficult to establish causation relations between individual factors and transmission rates. In order to evaluate the reaction of susceptible people to avoid infection during the outbreak, the rate of transmission is modeled through a unique phenomenological probabilistic approach, allowing the expression of the rate of generation of new cases in terms of two characteristics of the susceptible group: the frequency of sexual encounters and the probability of transmission given that there is a sexual encounter. Transmission rates are obtained and compared for the U.S. and several other countries. Results show reductions of up to 71% in the transmissibility parameter, which may be combined with variations in the frequency of sexual encounters (obtained through behavioral research) to determine the changes in the probability of transmission during an outbreak in a much more convenient way than current alternatives. This framework presents a valuable tool to health authorities in the understanding of future sexually transmissible disease outbreaks.

An Exploratory Study of Jamaican Women's Health Beliefs around Male Condom Use and Negotiation in Jamaica

This study explored African-Jamaican women's lived experiences and meanings around the communication and negotiation of male condoms used in their relationships. A qualitative phenomenological research design was utilized. Semi-structured interviews were collected with a small sample of nine African-Jamaican women living in Saint Mary, Jamaica. Results indicate that women's power in relationships may be masked, despite being at a disadvantage when communicating/negotiating male condom use. Several facilitators and barriers for communicating/negotiating condom use were identified. Interventions developed to combat the HIV epidemic in Islington, Saint Mary, must take into consideration structural factors in curbing the spread of HIV/AIDS.

Sexual Partnership-Level Correlates of Intimate Partner Violence Among Men Who Have Sex with Men and Transgender Women in Lima, Peru

To improve understanding of factors associated with intimate partner violence (IPV) and explore its role in sexually transmitted infection (STI) acquisition, we analyzed partnership-level correlates of IPV among men who have sex with men (MSM) and transgender women (TW) in Peru. In a 2017 cross-sectional study of rectal STI screening and HIV prevention, MSM/TW completed a sociobehavioral survey addressing demographic characteristics, sexual risk behaviors, and substance use, and were tested for rectal gonorrhea and chlamydia, syphilis, and HIV. Generalized estimating equations estimated individual- and partner-level correlates of IPV. Of 576 participants (median age, 27 years), 7.9% (36/456) of MSM and 15.0% (18/120) of TW reported IPV with ≥ 1 of their last three partners. MSM/TW reporting IPV were more likely to meet criteria for an alcohol use disorder (74.1%) than participants reporting no IPV (56.7%; p < .01). Physical violence (4.5% MSM; 9.2% TW) was associated with stable partnerships (aPR 3.79, 95% CI 1.79-8.04), partner concurrency (4.42, 1.19-16.40), and participant alcohol (4.71, 1.82-12.17) or drug use (5.38, 2.22-13.02) prior to sex. Psychological violence (4.5% MSM; 5.0% TW) was associated with stable partnerships (2.84, 1.01-7.99). Sexual IPV was reported by 1.1% of MSM and 5.0% of TW. Physical, psychological, and sexual IPV were reported in sexual partnerships of Peruvian MSM and TW, particularly with stable partners and in conjunction with substance use.

Sexual Partner Types and Incident HIV Infection Among Rural South African Adolescent Girls and Young Women Enrolled in HPTN 068: A Latent Class Analysis

BACKGROUND

Sexual partners are the primary source of incident HIV infection among adolescent girls and young women (AGYW) in sub-Saharan Africa. Identifying partner types at greatest risk of HIV transmission could guide the design of tailored HIV prevention interventions.

METHODS

We conducted a secondary analysis of data from AGYW (aged 13-23 years) enrolled in a randomized controlled trial of cash transfers for HIV prevention in South Africa. Annually, AGYW reported behavioral and demographic characteristics of their 3 most recent sexual partners, categorized each partner using prespecified labels, and received HIV testing. We used latent class analysis (LCA) to identify partner types from reported characteristics, and generalized estimating equations to estimate the relationship between both LCA-identified and prespecified partner types and incident HIV infection.

RESULTS

Across 2140 AGYW visits, 1034 AGYW made 2968 partner reports and 63 AGYW acquired HIV infection. We identified 5 LCA partner types, which we named monogamous HIV-negative peer partner; one-time protected in-school peer partner; out-of-school older partner; anonymous out-of-school peer partner; and cohabiting with children in-school peer partner. Compared to AGYW with only monogamous HIV-negative peer partners, AGYW with out-of-school older partners had 2.56 times the annual risk of HIV infection (95% confidence interval: 1.23 to 5.33), whereas AGYW with anonymous out-of-school peer partners had 1.72 times the risk (95% confidence interval: 0.82 to 3.59). Prespecified partner types were not associated with incident HIV.

CONCLUSION

By identifying meaningful combinations of partner characteristics and predicting the corresponding risk of HIV acquisition among AGYW, LCA-identified partner types may provide new insights for the design of tailored HIV prevention interventions.

Sexual Concurrency and Contraceptive Use Among Young Adult Women

Leveraging 2.5 years of weekly data from the Relationship Dynamics and Social Life Study, we investigate the relationship between young women's sexual concurrency and their contraceptive behavior. Specifically, we (1) examine whether young women changed their contraceptive use when switching from one to multiple concurrent sexual partners in the same week; (2) explore the uniformity of contraceptive responses to concurrency across relationship context; and (3) compare the contraceptive behaviors of never-concurrent women with those of ever-concurrent women in weeks when they were not concurrent. Nearly one in five sexually active young women had sex with two or more people in the same week. When they were concurrent, these women's odds of using any contraception increased threefold, and their odds of using condoms increased fourfold. This pattern of contraceptive adjustments was the same across relationship characteristics, such as duration and exclusivity. Yet when they were not concurrent, ever-concurrent women were less likely to use any contraception and used condoms less consistently than women who were never concurrent. We discuss these findings in the context of ongoing debates about the role of sexual concurrency in STI transmission dynamics.

Does HIV Pre-Exposure Prophylaxis Modify the Effect of Partnership Characteristics on Condom Use? A Cross-Sectional Study of Sexual Partnerships Among Men Who Have Sex with Men in San Francisco, California

Increasing rates of sexually transmitted infections (STIs) in the United States among men who have sex with men (MSM) have raised concerns that pre-exposure prophylaxis (PrEP) has been associated with higher engagement in condomless anal intercourse (CAI). While partnership characteristics have previously been found to influence condom use, the extent to which PrEP use may modify their effect on CAI remains unknown. A secondary analysis of 535 sexual partnerships from a cross-sectional study in San Francisco was conducted to evaluate interactions between PrEP use and partnership characteristics on CAI. Bivariate and multivariate generalized estimating equation (GEE) logistic regression models were used to estimate relative measures of association, adjusted for confounding by seroconcordance and partnership type, as well as account for repeated partnerships per respondent. Partnerships where both partners used biomedical prevention had significantly greater odds of CAI [odds ratio (OR) = 5.19, 95% confidence interval (CI): 2.27-11.9] compared to those where only one partner used biomedical prevention, while those where neither partner used biomedical prevention had significantly lower odds of CAI (OR = 0.61, 95% CI: 0.40-0.93). There was no significant association between meeting place (online vs. offline) and sexual risk taking (OR = 1.03, p = 0.894). Having one partner disclose their HIV status (compared to neither partner having disclosed) was associated with significantly higher odds of CAI among partnerships of PrEP-using MSM [adjusted OR (aOR) = 5.28, 95% CI: 1.91-14.61], while the association was not significant among the partnerships of non-PrEP-using MSM (aOR = 1.29, 95% CI: 0.75-2.21). Differences in condom use among MSM using PrEP may not be well explained by differences in the effect of partnership characteristics. MSM using PrEP appear to commonly practice biomedical matching and high engagement in CAI with other biomedical prevention users, which could indicate relatively concentrated sexual networks and partly explain their disproportionate risk for STIs. Future studies should further investigate biomedical matching to develop interventions that further promote the sexual health of those using PrEP.

Concurrency and other sexual partnership patterns reported in a survey of young people in rural Northern Tanzania

African adolescents and young adults remain at substantial risk of infection with HIV and other sexually transmitted infections (STIs), and AIDS is the leading cause of death among African adolescents (10–19 years). Sexual partnership patterns influence transmission risk of sexually transmitted infections. We describe patterns reported by youth (15-30y) in a community-based survey in Tanzania. Among participants reporting multiple partners, we investigated factors associated with reported concurrency. Female (N = 6513) and male (N = 7301) participants had median ages of 21 and 22 years, respectively. Most participants (92%) reported having previously been sexually active, of whom 15% of males and <1% of females reported ≥4 partners in the past year. The point prevalence of concurrency was 2.3% (95%CI 1.9–2.9) for females and 10.6% (95%CI 9.3–12.1) for males. High levels of multiple and concurrent partnerships were reported by those previously married. Females were more likely than males to report having spousal/regular partners and longer partnership lengths. Compared to males, the partnerships reported by females were less likely to be new partnerships, and more likely to be defined by the respondent as still ‘ongoing’. Females reporting younger sexual debut were more likely to report concurrent sexual partners. Far fewer young women reported multiple and concurrent partnerships, but we cannot definitively conclude that concurrency was uncommon for women, because stigma towards women’s multiple sexual partnerships might contribute to substantial under-reporting, as was found in extensive qualitative research in the study population. This study provides one of the most comprehensive quantitative descriptions of partnership patterns of young people in an African setting. Interventions addressing sexual risk among youth should involve male partners, empower women to protect themselves within different types of partnerships, and encourage a greater openness about young people’s sexual relationships.

Sex with older partners, condomless anal sex and unrecognized HIV infection among Chinese men who have sex with men

We examined the prevalence of sex with older male partner (SWOMP) and its association with condomless anal intercourse (CAI) with male partners and unrecognized HIV infection among young men who have sex with men (MSM) in Shanghai, China. The analytic sample included 243 MSM who were 18-45 years and HIV negative or of unknown HIV serostatus. Older male partner refers to male sex partner who was at least 10 years older than themselves. Overall, 99 (43.0%) and 50 (20.7%) reported having SWOMP in lifetime and in the last 3 months, respectively. Having any CAI with male partners in the last 3 months was independently associated with SWOMP and sex with stable male partners in the last 3 months. Unrecognized HIV infection was independently associated with being HSV-2 positive and having any CAI with male partners as well as SWOMP in last 3 months. Sex with stable male partner in the last 3 months was also marginally significantly associated with unrecognized infection (p = 0.084). Older partner selection is common among young MSM in China. Prevention programs should incorporate education messages about the HIV risk associated with SWOMP. MSM should be informed that having condomless sex with stable partners may place them at HIV risk.

Relationship-Based Predictors of Sexual Risk for HIV Among MSM Couples: A Systematic Review of the Literature

Behavioral and epidemiological studies report high risk for HIV among MSM couples. Over the last decade, studies have examined relationship dynamics associated with sexual risk for HIV. It is important to examine the impact this research has had on HIV prevention and what is still needed. We conducted a review of the literature focusing on relationship dynamics associated with sexual risk for HIV among MSM couples. Procedures used for this review were guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses established to provide a framework for collecting, reviewing and reporting studies systematically (Mohler et al. in Ann Intern Med 151(4):264-269, 2009). We found that positive relationship dynamics are associated with less risk with partners outside the relationship, but were associated with greater odds of unprotected anal intercourse with primary partners. We also discuss other factors including sexual agreements about outside partners and make recommendations for next steps in HIV prevention research among MSM couples.

Anticipated Notification of Sexual Partners following STD Diagnosis among Men Who Have Sex with Men and Transgender Women in Lima, Peru: A Mixed Methods Analysis

BACKGROUND

New strategies to support partner notification (PN) are critical for STD control and require detailed understanding of how specific individual and partnership characteristics guide notification decisions.

METHODS

From 2011 to 2012, 397 MSM and TW recently diagnosed with HIV, syphilis, or another STD completed a survey on anticipated notification of recent sexual partners and associated factors. Qualitative interviews were conducted with a subset of participants to provide further depth to quantitative findings. Prevalence ratios and generalized estimating equation (GEE) models were used to analyze participant- and partner-level factors associated with anticipated PN.

RESULTS

Among all partners reported, 52.5% were described as "Very Likely" or "Somewhat Likely" to be notified. Anticipated notification was more likely for main partners than casual (adjusted Prevalence Ratio [aPR], 95% CI: 0.63, 0.54-0.75) or commercial (aPR, 95% CI: 0.44, 0.31-0.62) partners. Other factors associated with likely notification included perception of the partner as an STD source (aPR, 95% CI: 1.27, 1.10-1.48) and anticipated future sexual contact with the partner (aPR, 95% CI: 1.30, 1.11-1.52). An HIV diagnosis was associated with a lower likelihood of notification than non-HIV STDs (aPR: 0.68, 0.55-0.86). Qualitative discussion of the barriers and incentives to PN reflected a similar differentiation of anticipated notification according to partnership type and type of HIV/STD diagnosis.

DISCUSSION

Detailed attention to how partnership characteristics guide notification outcomes is essential to the development of new PN strategies. By accurately and thoroughly assessing the diversity of partnership interactions among individuals with HIV/STD, new notification techniques can be tailored to partner-specific circumstances.

Enhancing HIV Prevention Among Young Men Who Have Sex With Men: A Systematic Review of HIV Behavioral Interventions for Young Gay and Bisexual Men

Men who have sex with men (MSM) represent 64.0% of people living with HIV (PLWH) over the age of 13 years. Young men who have sex with men (YMSM) are particularly affected by HIV/AIDS; the rate of HIV infection for YMSM between the ages of 13 and 24 represents 72.0% of new infections among youth. To understand the current state of the science meant to prevent HIV for YMSM, we reviewed studies of HIV behavioral prevention interventions for YMSM. Five literature databases were searched, from their inception through October 2015, using key words associated with HIV prevention intervention evaluation studies for YMSM. The review criteria included behavioral HIV/AIDS prevention interventions, articles published in English-language peer-reviewed journals, YMSM between 13 and 24 years of age, and longitudinal repeated measures design. A total of 15 YMSM behavioral HIV prevention intervention studies were identified that met inclusion criteria and reported statistically significant findings. Common outcomes included unprotected sexual intercourse, HIV/AIDS risk behavior, condom use, HIV testing, safer sex attitude, and HIV prevention communication. Participant age, representation of Black/African American YMSM, application of theoretical and model underpinnings, congruence of assessment measures used, follow-up assessment times, and application of process evaluation were inconsistent across studies. To advance HIV prevention intervention research for YMSM, future studies should be theory-based, identify common constructs, utilize standard measures, include process evaluation, and evaluate sustained change over standard periods of time. HIV prevention interventions should incorporate the needs of the diverse, well-educated, web-connected millennial generation and differentiate between adolescent YMSM (13 to 18 years of age) and young adulthood YMSM (19 to 24 years of age). Because Black/African American YMSM represent more than 50% of new HIV infections, future HIV prevention intervention studies should prioritize these young men.

Brief motivational intervention to reduce alcohol and HIV/sexual risk behavior in emergency department patients: A randomized controlled trial

OBJECTIVE

Given the prevalence of co-occurring risky sexual behavior and drinking among emergency department (ED) patients, we developed a motivational intervention (MI) to address both behaviors. This study tested efficacy of a single-session MI compared to brief advice (BA) for reducing heavy drinking and condomless sex in adult ED patients screening positive for both.

METHOD

We randomized 372 patients to MI (n = 184) or BA (n = 188). Alcohol and sex risk outcomes were assessed over 9 months.

RESULTS

Generalized estimating equations models analyzing 327 patients with follow-up data provided strong support for efficacy of this integrated alcohol and sex-risk MI. Compared to BA, and after controlling for baseline covariates, those in MI reported significantly fewer heavy drinking days, drinks per week, and were less likely to engage in excessive drinking over follow-up (all ps < .05). MI was also favored over BA for reducing sex risk. Compared to BA, those in MI reported significantly fewer days on which they engaged in condomless sex with casual partners, had lower odds of reporting any condomless sex with a casual partner, and reported fewer days of sex under the influence of alcohol/other drugs (all ps < .05).

CONCLUSION

This innovative MI was acceptable, feasible, and successfully delivered in 2 community hospitals and thus shows great promise for scalability and dissemination into complex health settings where newly insured at-risk individuals are likely to seek care. (PsycINFO Database Record

"Manejar la Situacion": Partner Notification, Partner Management, and Conceptual Frameworks for HIV/STI Control Among MSM in Peru

Previous analyses of partner notification (PN) have addressed individual, interpersonal, social, and structural issues influencing PN outcomes but have paid less attention to the conceptual framework of PN itself. We conducted 18 individual interviews and 8 group discussions, in a two-stage qualitative research process, to explore the meanings and contexts of PN for sexually transmitted infections (STI) among men who have sex with men (MSM) and men who have sex with men and women (MSMW) in Lima, Peru. Participants described PN as the open disclosure of private, potentially stigmatizing information that could strengthen or disrupt a partnership, structured by the tension between concealment and revelation. In addition to informing partners of an STI diagnosis, the act of PN was believed to reveal other potentially stigmatizing information related to sexual identity and practices such as homosexuality, promiscuity, and HIV co-infection. In this context, the potential development of visible, biological STI symptoms represented a risk for disruption of the boundary between secrecy and disclosure that could result in involuntary disclosure of STI status. To address the conflict between concealment and disclosure, participants cited efforts to "manejar la situacion" (manage the situation) by controlling the biological risks of STI exposure without openly disclosing STI status. We use this concept of "managing the situation" as a practical and theoretical framework for comprehensive Partner Management for HIV/STI control systems among MSM in Latin America.

Neighborhood-level associations with HIV infection among young men who have sex with men in Chicago

The rising incidence of HIV infection among young men who have sex with men (YMSM) is a substantial public health concern. Traditional research on HIV among YMSM has focused largely on individual-level predictors and infrequently accounts for contextual or neighborhood-level factors such as ethnic composition and socioeconomic status. This study used neighborhood-level data from the US Census and other public sources, and individual-level data from a longitudinal cohort of YMSM in Chicago (Crew 450). Of the original 450 YMSM in the cohort, 376 reported living in Chicago (83.6 %) and were included in the analytic sample. A clustering approach was used to group the 77 community areas together by common characteristics, resulting in the identification of 11 distinct clusters. An unconditional model of individual HIV status indicated a significant amount of variance existed between neighborhood clusters (χ (2) = 21.66; p = 0.006). When individual-level variables were added to the model, only having an HIV-positive sex partner (OR = 6.41; CI 2.40, 17.1) and engaging in exchange sex in the past 6 months (OR = 3.25; 95 % CI 1.33, 7.93) were significant predictors of HIV status. Clusters with higher Walk Scores were less likely to contain HIV-positive individuals (OR = 0.94; 95 % CI 0.90, 0.98). Conversely, clusters with a larger proportion of vacant buildings were more likely to contain HIV-positive individuals (OR = 1.19; 95 % CI 1.07, 1.33). Future research among YMSM needs to investigate the mechanisms by which neighborhood of residence might influence engagement in risk behaviors or acquisition of HIV.

Concurrent partnerships and HIV risk among men who have sex with men in New York City

BACKGROUND

Concurrent partnerships are a significant public health concern among men who have sex with men (MSM). This study describes the prevalence of concurrency and its association with serodiscordant/serostatus unknown unprotected anal or vaginal intercourse (SDUI) among MSM in New York City.

METHODS

A total of 1458 MSM completed a social and sexual network inventory about their male and female sex partners, including concurrency, in the last 3 months. Logistic regression identified factors associated with SDUI.

RESULTS

Median age was 29 years. The proportion of participants who reported being HIV+ was 23.5%. The men reported a mean of 3.2 male partners in the last 3 months. The proportion of MSM who reported having recent SDUI was 16.6%. More than half (63.2%) described having concurrent sex partners (individual concurrency based on overlapping dates of relationships); 71.5% reported having partners whom they believed had concurrent partners (perceived partner concurrency); and 56.1% reported that both they and their partners had concurrent partners (reciprocal concurrency). Among HIV+ men by self-report, having SDUI was positively associated with individual concurrency, any alcohol use during sex, having more male sex partners, and not having a main partner. Among self-reported HIV- men, having SDUI was positively associated with perceived partner concurrency, lower education level, any alcohol and drug use during sex, having more male sex partners, and having an anonymous partner.

CONCLUSIONS

Concurrency was common among MSM. The association of SDUI with individual and perceived partner concurrency, along with substance use during sex, having an anonymous partner, and having many sex partners likely further increases HIV acquisition and transmission risk among MSM. HIV prevention interventions should address concurrency among MSM.

Individualized diagnosis interventions can add significant effectiveness in reducing human immunodeficiency virus incidence among men who have sex with men: insights from Southern California

PURPOSE

In this article, we examine the effectiveness of a variety of HIV diagnosis interventions in recently HIV-diagnosed men who have sex with men (MSM). These interventions use the preventive potential of postdiagnosis behavior change (PDBC), as measured by the reduction in the number of new infections. Empirical evidence for PDBC was presented in the behavioral substudy of the Southern California Acute Infection and Early Disease Research Program. In previous modeling work, we demonstrated the existing preventive effects of PDBC. However, a large proportion of new infections among MSM are either undiagnosed or diagnosed late, and the preventive potential of PDBC is not fully utilized.

METHODS

We derive empirical, stochastic, network-based models to examine the effectiveness of several diagnosis interventions that account for PDBC among MSM over a 10-year period. These interventions involve tests with shorter detection windows, more frequent testing, and individualized testing regimens.

RESULTS

We find that individualized testing interventions (i.e., testing individuals every three partners or 3 months, whichever is first, or every six partners or 6 months, whichever is first) result in significantly fewer new HIV infections than the generalized interventions we consider.

CONCLUSIONS

This work highlights the potential of individualized interventions for new public health policies in HIV prevention.

The risk of stable partnerships: associations between partnership characteristics and unprotected anal intercourse among men who have sex with men and transgender women recently diagnosed with HIV and/or STI in Lima, Peru

BACKGROUND

Partnership type is an important factor associated with unprotected anal intercourse (UAI) and subsequent risk for HIV and sexually transmitted infections (STI). We examined the association of partnership type with UAI among men who have sex with men (MSM) and male-to-female transgender women (TGW) in Lima, Peru, recently diagnosed with HIV and/or STI.

METHODS

We report data from a cross-sectional analysis of MSM and TGW recently diagnosed with HIV and/or STI in Lima, Peru between 2011 and 2012. We surveyed participants regarding UAI with up to their three most recent sexual partners according to partner type. Multivariable Generalized Estimate Equating (GEE) models with Poisson distribution were used to estimate prevalence ratios (PR) for UAI according to partner type.

RESULTS

Among 339 MSM and TGW recently diagnosed with HIV and/or STI (mean age: 30.6 years, SD 9.0), 65.5% self-identified as homosexual/gay, 16.0% as bisexual, 15.2% as male-to-female transgender, and 3.3% as heterosexual. Participants provided information on 893 recent male or TGW partners with whom they had engaged in insertive or receptive anal intercourse: 28.9% stable partners, 56.4% non-stable/non-transactional partners (i.e. casual or anonymous), and 14.7% transactional partners (i.e. transactional sex client or sex worker). Unprotected anal intercourse was reported with 41.3% of all partners. In multivariable analysis, factors associated with UAI included partnership type (non-stable/non-transactional partner APR 0.73, [95% CI 0.59-0.91], transactional partner APR 0.53 [0.36-0.78], p<0.05) and the number of previous sexual encounters with the partner (>10 encounters APR 1.43 [1.06-1.92], p<0.05).

CONCLUSION

UAI was more commonly reported for stable partners and in partnerships with >10 sexual encounters, suggesting UAI is more prevalent in partnerships with a greater degree of interpersonal commitment. Further research assessing partner-level factors and behavior is critical for improving HIV and/or STI prevention efforts among Peruvian MSM and TGW.

The effects of sexual partnership and relationship characteristics on three sexual risk variables in young men who have sex with men

Young men who have sex with men (YMSM) in the United States are experiencing an alarming increase in HIV incidence. Recent evidence suggests that the majority of new HIV infections in YMSM occur in the context of serious relationships, which underscores the importance of examining predictors of sexual risk behavior in the context of sexual partnerships, including relationship type, sexual partner characteristics, and relationship dynamics. The current study aimed to evaluate relationship and sexual partnership influences on sexual risk behavior in YMSM, including differentiating between multiple sexual risk variables (i.e., any unprotected anal or vaginal intercourse, unprotected insertive anal or vaginal intercourse, and unprotected receptive anal intercourse). More serious/familiar partnerships were associated with more sexual risk across all three risk variables, while wanting a relationship to last was protective against risk across all three risk variables. Some variables were differentially linked to unprotected insertive sex (partner gender) or unprotected receptive sex (partner age, partner race, believing a partner was having sex with others, and partners repeated across waves). Sexual risk behavior in YMSM is inconsistent across sexual partnerships and appears to be determined in no small part by sexual partner characteristics, relationship dynamics, and sexual role (i.e., insertive or receptive partner). These influences are critical in understanding sexual risk in YMSM and provide important targets for intervention.

Concurrent partnering and condom use among rural heterosexual African-American men

Background Limited research has targeted HIV risk among heterosexual African-American men in the rural south-eastern United States.

METHODS

A cross-sectional survey was administered to 538 men to assess HIV knowledge, attitudes towards HIV testing and sexual risk behaviour.

RESULTS

Fifty-one percent reported consistent condom use in the past 3 months. Monogamous men reported more consistent condom use (t=3.47, d.f.=536, P<0.001). In concurrent partnerships, condom use was inversely related to age (adjusted odds ratio (AOR)=0.98, 95% confidence interval (CI)=0.95-0.998, P=0.03) and increased with the number of female partners (AOR=1.49, 95% CI=1.26-1.76, P<0.001).

CONCLUSIONS

African-American HIV prevention outreach should include focus on concurrent partnering in rural settings.

Condom use and concurrent partnering among heterosexually active, African American men: a qualitative report

African Americans are overrepresented among heterosexual cases of HIV/AIDS in the USA. Inconsistent condom use and concurrent partnering are two sexual behaviors driving the heterosexual HIV epidemic in the African American community. To inform the development of an HIV prevention behavioral intervention to decrease concurrent partnering and increase condom use among African American heterosexual men, we conducted formative research, including 61 structured interviews, 5 focus groups with 25 men, and 30 in-depth qualitative interviews between July and December 2009. We used a grounded theoretical approach and categorizing strategies to code and analyze the qualitative data. Results around condom use confirmed earlier findings among heterosexual men in general: condoms diminish pleasure, interfere with erection, and symbolize infidelity. Although valued by some as a form of disease prevention and pregnancy prevention, condoms are often used only with specific types of female partners, such as new or casual partners, or due to visual risk assessment. Sex partner concurrency was described as normative and ascribed to men's "natural" desire to engage in a variety of sexual activities or their high sex drive, with little recognition of the role it plays in the heterosexual HIV epidemic. Fatherhood emerged among many men as a crucial life event and compelling motivation for reducing sexual risk behavior. Based on these results, we conclude that existing HIV prevention efforts to improve attitudes towards and motivate use of condoms either have not reached or have not been successful with African American heterosexual men. In designing behavioral interventions to decrease concurrent partnering and increase condom use, addressing negative attitudes towards condoms and partner risk assessment is critical, as is integrating novel motivational approaches related to identity as fathers and men in the African American community.

Factors associated with men in HIV-negative gay couples who practiced UAI within and outside of their relationship

Despite recent advances in research with gay male couples, less data exists about men who have had UAI within and outside of their HIV-negative seroconcordant relationship. Multilevel modeling with dyadic data from 142 couples was used to identify the characteristics associated with men who have had UAI with both their main partner and a casual MSM partner within the same timeframe. Analyses revealed that men were more likely to have had UAI within and outside of their relationship if they perceived their main partner has had a recent HIV test. Men were less likely to have had UAI within and outside of their relationship if they valued their sexual agreement and reported having a sexual agreement that does not allow sex outside of their relationship. Research with a more diverse sample of couples is warranted. Future interventions must consider the complexity of relationships and sexual behaviors among gay male couples.

High prevalence of sexual concurrency and concurrent unprotected anal intercourse across racial/ethnic groups among a national, Web-based study of men who have sex with men in the United States

BACKGROUND

Men who have sex with men (MSM) are the largest human immunodeficiency virus (HIV) risk group in the United States. Sexual concurrency may contribute to high HIV incidence or to racial/ethnic HIV disparities among MSM. Limited information is available on concurrency and racial/ethnic differences among MSM or on the extent to which MSM engage in concurrent unprotected anal intercourse (UAI).

METHODS

Data are from baseline responses in a prospective online study of MSM aged 18 years or older, having 1 or more male sex partners in the past 12 months, and recruited from social networking Web sites. Pairwise sexual concurrency and UAI in the previous 6 months among up to 5 recent partners was measured, using an interactive questionnaire. Period prevalences of concurrency and concurrent UAI were computed and compared across racial/ethnic groups at the individual and triad (a respondent and 2 sex partners) levels.

RESULTS

A total of 2940 MSM reported on 8911 partnerships; 45% indicated concurrent partnerships, and 16% indicated concurrent UAI in the previous 6 months. Respondents were more likely to have UAI with 2 partners when they were concurrent, compared to serially monogamous (odds ratio, 1.93, 95% confidence interval, 1.75-2.14). No significant differences in levels of individual concurrency or concurrency among triads were found between non-Hispanic white, non-Hispanic black, and Hispanic men.

CONCLUSIONS

Concurrency and concurrent UAI in the previous 6 months was common. Although there were no differences by race/ethnicity, the high levels of concurrency and concurrent UAI may be catalyzing the transmission of HIV among MSM in general.

Straight talk: HIV prevention for African-American heterosexual men: theoretical bases and intervention design

In the United States, racial disparities in HIV/AIDS are stark. Although African Americans comprise an estimated 14% of the U.S. population, they made up 52% of new HIV cases among adults and adolescents diagnosed in 2009. Heterosexual transmission is now the second leading cause of HIV in the United States. African Americans made up a full two-thirds of all heterosexually acquired HIV/AIDS cases between 2005 and 2008. Few demonstrated efficacious HIV prevention interventions designed specifically for adult, African-American heterosexual men exist. Here, we describe the process used to design a theory-based HIV prevention intervention to increase condom use, reduce concurrent partnering, and increase HIV testing among heterosexually active African-American men living in high HIV prevalence areas of New York City. The intervention integrated empowerment, social identity, and rational choices theories and focused on four major content areas: HIV/AIDS testing and education; condom skills training; key relational and behavioral turning points; and masculinity and fatherhood.

Variation in concurrent sexual partnerships and sexually transmitted diseases among African men in Cape Town, South Africa

BACKGROUND

Most studies that assess the relationship between concurrent sexual partnerships and sexually transmitted diseases (STDs) use dichotomous measures of whether concurrency was reported or not. However, different forms of concurrency have different degrees of associated risk for disease transmission, and this should be considered. This article examines variation in both individual concurrency and partner concurrency among African men in Cape Town, South Africa, and assesses the relationship between different types of concurrent partnerships and STDs.

METHODS

Longitudinal data from sexual partner history tables are used to form measures of concurrency and the type of partner (main vs. nonmain) and degree of condom use (consistent vs. inconsistent) associated with these concurrent relationships. Cross-sectional data from a self-administered module are also used to assess the number of partners men have had concurrently and duration of individual concurrency. Probit regression models assess the association between the partner concurrency measures and self-reported STD history.

RESULTS

Substantial differences between concurrent sexual partnerships were observed and these variations were associated with different disease risk. Men had a greater chance of reporting an STD when partner concurrency was associated with main partners and inconsistent condom use.

CONCLUSION

Partnership dynamics must be taken into account in studies assessing the role of concurrency in STD transmission.

Discussion of HIV status by serostatus and partnership sexual risk among internet-using MSM in the United States

Men who have sex with men (MSM), particularly black MSM, are disproportionally infected with HIV. Little is known about how discussion of HIV status between partners varies among MSM by race/ethnicity and by HIV transmission risk. Among a national survey of 2031 MSM reporting 5410 partnerships, black MSM, especially black HIV-positive MSM, serodiscussed with unprotected anal intercourse partners less than did white MSM. Although non-black HIV-positive, non-black HIV-negative MSM, and black HIV-negative MSM were more likely to report serodiscussion with unprotected anal intercourse partners, black HIV-positive MSM were not. Differential serodiscussion may play a role in explaining the racial/ethnic disparity in HIV incidence.

Partner-provided social support influences choice of risk reduction strategies in gay male couples

We investigated the influence of partner-provided HIV-specific and general social support on the sexual risk behavior of gay male couples with concordant, discordant, or serostatus-unknown outside partners. Participants were 566 gay male couples from the San Francisco Bay Area. HIV-specific social support was a consistent predictor for reduced unprotected anal intercourse (UAI) with both concordant outside partners (all couple types) and outside partners of discordant or unknown serostatus (concordant negative and discordant couples). General social support was associated with increased UAI with concordant outside partners for concordant negative and concordant positive couples (i.e., serosorting). Our findings suggest that prevention efforts should target couples and identify the level of HIV-specific support that partners provide. Partner-provided support for HIV-related behaviors could be an additional construct to consider in gay male relationships, akin to relationship satisfaction and commitment, as well as an important component of future HIV prevention interventions.

Beyond Sexual Partnerships: The Lack of Condom Use during Vaginal Sex with Steady Partners

PURPOSE

The purpose of this paper is to identify independent correlates of the lack of condom use when engaging in vaginal sex with steady partners among HIV-negative African American adults. The conceptual model includes proximal as well as more distal domains.

METHODS

Cross-sectional data were collected between May 2009 and August 2011. Recruitment involved active and passive recruitment strategies. Computer-assisted, individual interviews were conducted with 1,050 African American adults. Multivariate logistic regression was used to identify independent predictors of a lack of condom use with steady partners in the past 30 days.

RESULTS

In multivariate analysis, being older than 35, being partnered, perceiving having a steady partner as important, and ever having been homeless were associated positively with the odds of a lack of condom use during vaginal sex with steady partners in the past 30 days. On the other hand, reporting more than one steady partner in the past 30 days, having health insurance during the past 12 months, and perceived neighborhood social cohesion were negatively associated.

CONCLUSIONS

These findings highlight the need for HIV risk-reduction prevention and intervention efforts that consider distal as well as proximal domains. Such a perspective allows for a broader sociological inquiry into health disparities that moves beyond epidemiological factors that commonly guide public health research.

Relationship characteristics and sexual risk-taking in young men who have sex with men

OBJECTIVE

Young men who have sex with men (MSM), particularly young men of color, are experiencing the largest increase in HIV incidence of any risk group in the United States Epidemiological research suggests that the majority of transmissions among MSM are occurring in the context of primary partnerships, but little research has been done on the processes within these dyads that increase HIV risk behaviors. The aim of this study was to use longitudinal partnership-level data to explore the effects of partner and relationship characteristics on the frequency of unprotected sex within young MSM relationships.

METHOD

One hundred twenty-two young MSM (age 16-20 at baseline) were assessed at three time-points six months apart, with 91% retention at the 12-month follow-up wave. Over 80% were racial/ethnic minorities. At each wave, participants reported on characteristics of the relationships and partners for up to three sexual partners. Hierarchical linear modeling was used for analyses.

RESULTS

The largest effect was for considering the relationship to be serious, which was associated with nearly an eightfold increase in the rate of unprotected sex. Other factors that increased risk behaviors included older partners, drug use prior to sex, physical violence, forced sex, and partnership lasting more than six months. Partners met online were not associated with significantly more sexual risk.

CONCLUSIONS

These data provide insight into the relationship processes that should be addressed in prevention programs targeted at young MSM. Relationships may serve as a promising unit for HIV prevention interventions, although more formative research will be required to address potential logistical obstacles to implementing such interventions. The partner-by-partner analytic approach (i.e., evaluating situational variables associated with several partners for a given participant) holds promise for future HIV behavioral research.

The relative role of perceived partner risks in promoting condom use in a three-city sample of high-risk, low-income women

We examined the effect of women’s perceptions of sexual partner risks on condom use. Women from three US cities (n = 1,967) were recruited to provide data on HIV risks. In univariate models, increased odds of condom use were associated with perceiving that partners had concurrent partners and being unaware of partners': (a) HIV status, (b) bisexuality, (c) concurrency; and/or (d) injection drug use. In multivariate models, neither being unaware of the four partner risk factors nor perceiving a partner as being high risk was associated with condom use. Contextual factors associated with decreased odds of condom use were having sex with a main partner, homelessness in the past year, alcohol use during sex, and crack use in the past 30 days. Awareness of a partner’s risks may not be sufficient for increasing condom use. Contextual factors, sex with a main partner in particular, decrease condom use despite awareness of partner risk factors.

Effect of patterns of transferring patients among healthcare institutions on rates of nosocomial methicillin-resistant Staphylococcus aureus transmission: a Monte Carlo simulation

OBJECTIVE

To determine the effect of the rate and pattern of patient transfers among institutions within a single metropolitan area on the rates of methicillin-resistant Staphylococcus aureus (MRSA) transmission among patients in hospitals and nursing homes.

METHODS

A stochastic, discrete-time, Monte Carlo simulation was used to model the rate and spread of MRSA transmission among patients in medical institutions within a single metropolitan area. Admission, discharges, transfers, and nosocomial transmission were simulated with respect to different interinstitutional transfer strategies and various situational scenarios, such as outlier institutions with high transmission rates.

RESULTS

The simulation results indicated that transfer patterns and transfer rate changes do not affect nosocomial MRSA transmission. Outlier institutions with high transmission rates affect the system wide rate of nosocomial infections differently, depending on institution type.

CONCLUSION

It is worth effort to understanding disease-transmission dynamics and interinstitutional transfer patterns for the management of recently introduced diseases or strains. Once endemic in a system, other strategies for transmission control need to be implemented.

Attitudes towards couples-based HIV testing among MSM in three US cities

Couples-based voluntary HIV counseling and testing (CVCT)--in which couples receive counseling and their HIV test results together--has been shown to be an effective strategy among heterosexual sero-discordant couples in Africa for reducing HIV transmission by initiating behavioral change. This study examined attitudes towards CVCT among men who have sex with men (MSM) in three US cities. Four focus group discussions (FGD) were held with MSM in Atlanta, Chicago, and Seattle. Although initially hesitant, participants reported an overwhelming acceptance of CVCT. CVCT was seen as a sign of commitment within a relationship and was reported to be more appropriate for men in longer-term relationships. CVCT was also seen as providing a forum for the discussion of risk-taking within the relationship. Our results suggest that there may be a demand for CVCT among MSM in the United States, but some modifications to the existing African CVCT protocol may be needed.

HIV in young men who have sex with men: a review of epidemiology, risk and protective factors, and interventions

Epidemiological studies have found that young men who have sex with men (YMSM) represent the majority of young people infected with HIV annually in the United States. Further, they are one of the few risk groups to show an increase in the rate of infections in recent years. In addition to these disparities in prevalence and infection rates, there is an inequity in prevention and intervention research on this population. The purpose of this article is to review the existing YMSM literature on HIV epidemiology, correlates of risk, and intervention research. The article concludes that promising future directions for basic research include a focus on multiple clustering health issues, processes that promote resiliency, the role of family influences, and the development of parsimonious models of risk. In terms of intervention research, the article suggests that promising future directions include Internet-based intervention delivery, integration of biomedical and behavioral approaches, and interventions that go beyond the individual level to address partnership, structural, community, and network factors.

Behaviors of recently HIV-infected men who have sex with men in the year postdiagnosis: effects of drug use and partner types

OBJECTIVES

Assess behavior change of recently HIV-infected men who have sex with men (MSM).

METHODS

From 2002 to 2006, 193 recently HIV-infected MSM in the Southern California Acute Infection and Early Disease Research Program were interviewed every 3 months. Changes in HIV status of partners, recent unprotected anal intercourse (UAI), drug use, use of antiretroviral therapy (ART), detectable viral load, and partnership dynamics over 1 year were used to predict recent UAI in a random effect logistic regression.

RESULTS

Over a year significantly fewer partners in the past 3 months were reported (mean 8.81 to 5.84; P < 0.0001). Percentage of recent UAI with HIV-status unknown last partners decreased from enrollment to 9 months (49%-27%) and rebounded at 12 months to 71%. In multivariable models controlling for ART use, recent UAI was significantly associated with: baseline methamphetamine use [adjusted odds ratio (AOR): 7.65, 95% confidence interval (CI): 1.87 to 31.30], methamphetamine use at follow-up (AOR: 14.4, 95% CI: 2.02 to 103.0), HIV-uninfected partner at follow-up (AOR: 0.14, 95% CI: 0.06 to 0.33), and partners with unknown HIV status at follow-up (AOR: 0.33, 95% CI: 0.11 to 0.94). HIV viral load did not influence rate of UAI.

CONCLUSIONS

Transmission behaviors of these recently HIV-infected MSM decreased and serosorting increased after diagnosis; recent UAI with serostatus unknown or negative partners rebounded after 9 months, identifying critical timepoints for interventions targeting recently HIV-infected individuals. There was no evidence in this cohort that the viral load of these recently infected men guided their decisions about protected or unprotected anal intercourse.

Neighborhood environment, sexual risk behaviors and acquisition of sexually transmitted infections among adolescents diagnosed with psychological disorders

The association between neighborhood environment and prevalence of STIs, sexual partner variables and condom use among adolescents with psychological disorders was examined. Cross-sectional data in three urban areas of the US (Southeast, Northeast and Midwest) were obtained from 384 sexually active male and female participants who provided urine samples for laboratory-confirmed testing of Neisseria gonorrhoeae, Chlamydia trachomatis and Trichomonas vaginalis. A total of 15.4% of participants tested positive for one of the three STIs. Results indicated that relative to adolescents living in low risk neighborhood environments, those living in high risk environments were significantly more likely to have a STI and to report having casual partners. Findings suggest that in high risk neighborhoods, STI acquisition may be less dependent on condom use and more dependent on other contextual factors. The importance of expanding public health research to include assessment of neighborhood context as a determinant of sexual risk-taking is emphasized.

Couples-focused behavioral interventions for prevention of HIV: systematic review of the state of evidence

HIV is frequently transmitted in the context of partners in a committed relationship, thus couples-focused HIV prevention interventions are a potentially promising modality for reducing infection. We conducted a systematic review of studies testing whether couples-focused behavioral prevention interventions reduce HIV transmission and risk behavior. We included studies using randomized controlled trial designs, quasi-randomized controlled trials, and nonrandomized controlled studies. We searched five electronic databases and screened 7,628 records. Six studies enrolling 1,084 index couples met inclusion criteria and were included in this review. Results across studies consistently indicated that couples-focused programs reduced unprotected sexual intercourse and increased condom use compared with control groups. However, studies were heterogeneous in population, type of intervention, comparison groups, and outcomes measures, and so meta-analysis to calculate pooled effects was inappropriate. Although couples-focused approaches to HIV prevention appear initially promising, additional research is necessary to build a stronger theoretical and methodological basis for couples-focused HIV prevention, and future interventions must pay closer attention to same-sex couples, adolescents, and young people in relationships.

The characteristics of sexual behavior and extent of condom usage among sexually active Croatians from Eastern Croatia

OBJECTIVE

To determine the extent of condom usage as a method of protection from sexually transmitted infections (STIs) among sexually active individuals obliged to present for periodical health examination at the Institute of Public Health for the Osijek-Baranya County, in Osijek, eastern Croatia.

MATERIAL AND METHODS

During February 2004, a cross-sectional questionnaire survey was conducted. The research tool was an unidentified 20-item questionnaire addressing the sexual behavior of study subjects and their partners and methods of protection from STIs. Descriptive statistics and χ(2) - test were used for data analysis.

RESULTS

The response rate was 84.2% (278/330). A total of 278 subjects, 96 (34.5%) males and 182 (65.5%) females, 167 (60.1%) married and 111 (39.9%) single, mean age 31.3±8.4, age range 18-52 years were enrolled in the study. Study results revealed 22.3% (62/278) subjects to have had two or more sexual partners over the one-year period and the use of condom was reported by 40.3% (25/62) of those subjects.

CONCLUSIONS

The obtained results point to the need for additional education on protection from sexually transmitted infections and on risky sexual behavior, with special reference to the role of condom usage in the prevention of these diseases and their detrimental effects on the reproductive health of sexually active individuals.

Comparison of sexual partnership characteristics and associations with inconsistent condom use among a sample of adolescents and adult women diagnosed with Chlamydia trachomatis

BACKGROUND

This analysis compared characteristics of female adolescent and adult sexual partnerships and related these characteristics to inconsistent condom use.

METHODS

Data are from a study of 126 women with prevalent chlamydia infections who reported information about 172 sexual partnerships in the previous 3 months. Characteristics of sexual partnerships included type of partner (main vs. other), duration of sexual relationship (<3 months vs. > or =3 months), partner age difference (<2 years older vs. > or =2 years older), and two scale measures: overlap of social networks (a measure based on how well the participant knew her partner's friends, for example) and intimacy.

RESULTS

Compared with adult partnerships, adolescent partnerships were of shorter duration and had less social overlap but were more likely to be classified by the participants as main partnerships. Among adolescents, longer partnership duration was not associated with higher intimacy, yet higher intimacy was significantly correlated with inconsistent condom use.

CONCLUSIONS

These differences suggest that adolescent females perceive and characterize their sexual relationships differently from adults. This, in turn, may have implications for risk of sexually transmitted infections (STIs). Prevention efforts for adolescents, including interventions and counseling, should consider the nature of their sexual partnerships.

What the better half is thinking: A comparison of men's and women's responses and agreement between spouses regarding reported sexual and reproductive behaviors in Rwanda

Objective

To compare responses to a sexual behavioral survey of spouses in cohabiting heterosexual relationships in Kigali, Rwanda.

Design

Cross-sectional survey.

Methods

Husbands and wives in 779 cohabiting couples were interviewed separately with parallel questionnaires. Participants were recruited from a three-year old cohort of 1458 antenatal clinic attendees enrolled in a prospective study in 1988. Analyses compared responses at the gender- and couple-level for agreement and disagreement.

Results

Couples were in disagreement more than agreement. Women reported occasionally refusing sex, suggesting condom use, and believing married men were unfaithful. Men reported being in a faithful relationship, greater condom use, and being understanding when wives refused sex. Agreement included relationship characteristics, safety of condoms, and whether condoms had ever been used in the relationship. Disagreement included the preferred timing of next pregnancy, desire for more children, and whether a birth control method was currently used and type of method.

Conclusions

Rwandan husbands and wives differed in sexual behavior and reproductive-related topics. Couple-level reporting provides the most reliable measure for relationship aspects as couples’ agreement cannot be assumed among cohabiting partnerships. Furthermore, HIV prevention programs for couples should incorporate communication skills to encourage couple agreement of HIV-related issues.

INTRODUCTION: The HIV and AIDS epidemic has quickly spread over the world with a tendency towards feminization, pauperization, and heterosexualization. Partner communication around HIV has been described as one protective factor for the acquisition of this disease, favoring the adoption of safe sexual practices, such as couple negotiation and condom use. Considering this is fundamental in the incorporation of self-care practices among female sexuality. OBJECTIVE: Determine the level of partner communication around HIV among socially disadvantaged Chilean women. METHODOLOGY: Four hundred and six (406) women responded the baseline interview for the research project "Testing and HIV/AIDS Prevention Intervention for Chilean Women" (RO1 TW 006977, PI. Cianelli). The scale Health Protective Sexual Communication Scale (HPC) was used (range between 0-10 points). A descriptive analysis was done using SPSS, version 16.0. RESULTS: The mean level of partner communication with the main partner was 3,26 +2,7 points, of 2,52 +2,48 points with the second partner, and 0 points with the third partner. The themes related with less partner communication were the condom use and getting an HIV test before having sexual intercourse. CONCLUSION: Women in the sample had low levels of partner communication in relation with HIV with all their sexual partners. Strategies within HIV/AIDS prevention programs are needed to trigger this area, in order to strengthen the adoption of self care behaviors around this issue.

HIV-positive men sexually active with women: sexual behaviors and sexual risks

This study examines patterns of sexual behavior, sexual relating, and sexual risk among HIV-positive men sexually active with women. A total of 278 HIV-positive men were interviewed every 6-12 months between 1994 and 2002 and reported considerable variability in sexual behaviors over time. Many were not sexually active at all for months at a time; many continued to have multiple female and at times male partners. Over one-third of the cohort had one or more periods when they had engaged in unprotected sex with a female partner who was HIV-negative or status unknown (unsafe sex). Periods of unsafe sex alternated with periods of safer sex. Contextual factors such as partner relations, housing status, active drug use, and recently exchanging sex showed the strongest association with increased odds of unsafe sex. A number of predictors of unsafe sex among African American men were not significant among the Latino sub-population, suggesting race/ethnic differences in factors contributing to heterosexual transmission. Implications for prevention interventions are discussed.

Ecstasy use and its association with sexual behaviors among drug users in New York City

In the past two decades, recreational use of ecstasy has become a growing concern in the United States, although most studies assessing ecstasy use have focused on white, middle-class adolescents who use ecstasy during raves and in clubs. We assessed the prevalence of recent ecstasy use among predominantly minority heroin, cocaine, and crack users in New York City and the association between ecstasy and sexual risk above and beyond that of the other drugs. Between 2002 and 2004, injection and non-injection heroin, crack and cocaine users (N= 534) completed a risk behavior questionnaire that included items on ecstasy use. Logistic regression was used to investigate the relation between current ecstasy use and sexual behaviors. Of 534 illicit drug users, 69.7% were aged 25 years or older, 65.2% were Hispanic, 27.9% Black and 77.4% male; 36.7% were injectors. 17.2% of respondents reported recent (last six months) ecstasy use. In a multivariable logistic regression model, current ecstasy use was associated both with initiating sex before age 14 (adjusted odds ratio (AOR) = 1.51) and having two or more partners in the past two months (AOR = 1.86) after adjusting for age at study entry, current cocaine and marijuana use and being an injection drug user. This study suggests that ecstasy use may be more prevalent among urban drug users. Ecstasy use in urban settings, beyond clubs and raves, should continue to be monitored.
