Disparities by Race and Ethnicity Among Adults Recruited for a Preclinical Alzheimer Disease Trial

Underrepresentation of many racial/ethnic groups in Alzheimer disease (AD) clinical trials limits generalizability of results and hinders opportunities to examine potential effect modification of candidate treatments. To examine racial and ethnic differences in recruitment methods and trial eligibility in a multisite preclinical AD trial. This cross-sectional study analyzed screening data from the Anti-Amyloid in Asymptomatic AD study, collected from April 2014 to December 2017. Participants were categorized into 5 mutually exclusive ethnic/racial groups (ie, Hispanic, Black, White, Asian, and other) using participant self-report. Data were analyzed from May through December 2020 and included 5945 cognitively unimpaired older adults between the ages of 65 and 85 years screened at North American study sites. Primary outcomes included recruitment sources, study eligibility, and ineligibility reasons. To assess the probability of trial eligibility, regression analyses were performed for the likelihood of being eligible after the first screening visit involving clinical and cognitive assessments. Screening data were included for 5945 participants at North American sites (mean [SD] age, 71.7 [4.9] years; 3524 women [59.3%]; 5107 White [85.9%], 323 Black [5.4%], 261 Hispanic [4.4%], 112 Asian [1.9%], and 142 [2.4%] who reported race or ethnicity as other). Recruitment sources differed by race and ethnicity. While White participants were recruited through a variety of sources, site local recruitment efforts resulted in the majority of Black (218 [69.2%]), Hispanic (154 [59.7%]), and Asian (61 [55.5%]) participants. Participants from underrepresented groups had lower mean years of education (eg, mean [SD] years: Hispanic participants, 15.5 [3.2] years vs White participants, 16.7 [2.8] years) and more frequently were women (226 [70.0%] Black participants vs 1364 [58.5%] White participants), were unmarried (184 [56.9%] Black participants vs 1364 [26.7%] White participants), and had nonspousal study partners (237 [73.4%] Black participants vs 2147 [42.0%] White participants). They were more frequently excluded for failure to meet cognitive inclusion criteria (eg, screen failures by specific inclusion criteria: 147 [45.5%] Black participants vs 1338 [26.2%] White participants). Compared with White participants, Black (odds ratio [OR], 0.43; 95% CI, 0.34-0.54; P < .001), Hispanic (OR, 0.53; 95% CI, 0.41-0.69; P < .001), and Asian participants (OR, 0.56; 95% CI, 0.38-0.82; P = .003) were less likely to be eligible after screening visit 1. Racial/ethnic groups differed in sources of recruitment, reasons for screen failure, and overall probability of eligibility in a preclinical AD trial. These results highlight the need for improved recruitment strategies and careful consideration of eligibility criteria when planning preclinical AD clinical trials.

Study partner types and prediction of cognitive performance: implications to preclinical Alzheimer\u2019s trials

BackgroundAlzheimer’s disease (AD) clinical trials require enrollment of a participant and a study partner, whose role includes assessing participant cognitive and functional performance. AD trials now investigate early stages of the disease, when participants are not cognitively impaired. This gives rise to the question of whether study partners or participants provide more information in these trials.MethodsWe used data from the AD Cooperative Study Prevention Instrument Project (ADCS-PI) to compare participant and study partner predictions of the participant’s current and future cognitive state. We used the Cognitive Function Instrument (CFI) as a measure of evaluation of the participant’s cognitive status and the modified ADCS Preclinical Alzheimer’s Cognitive Composite (mADCS-PACC) as an objective measure of cognition. Stratifying by cognitive status and study partner type and adjusting for other predictors of the participant’s cognitive state, we used random forests along with estimated mean variable importance (eMVI) to assess how well each member of the dyad can predict cognitive state at current and later visits. We also fit linear regression models at each time point and for each scenario.ResultsParticipants were better at predicting future cognitive status compared to their study partners regardless of study partner type, though the difference between participants and partners was greatest for non-spousal dyads in the lowest-performing quartile. Cross-sectional assessments differed substantially by dyad type. Within the lowest cognitive performance quartile, participants having a non-spousal study partner outperformed their partners in assessing cognition at later times. Spousal partners, in contrast, outperformed participants later in the study in predicting current cognitive performance.ConclusionsThese results indicate that participants tend to be better at predicting future cognition compared to their study partners regardless of the study partner type. When assessing current cognition, however, spousal study partners perform better at later time points and non-spousal study partners do not provide as much information regarding participant cognitive state.

Reduced frequency of HIV superinfection in a high-risk cohort in Zambia

Rates of HIV-1 superinfection, re-infection with a genetically distinct virus despite HIV-1 specific immune responses, vary in different risk populations. We previously found the rates of superinfection were similar to primary HIV infection (PHI) in a Zambian heterosexual transmission cohort. Here, we conduct a similar analysis of 47 HIV-positive Zambians from an acute infection cohort with more frequent follow-up, all infected by non-spousal partners. We identified only one case of superinfection in the first two years, significantly fewer than in our previous study, which was likely due to increased counseling during acute infection and an overall population-wide decline in factors associated with HIV transmission. The predominant virus detected after superinfection was a recombinant of the transmitted founder (TF) and the superinfecting strain. The superinfected individual mounted a neutralizing antibody response to the primary TF virus, which remained TF-specific over time and even after superinfection, did not neutralize the superinfecting variant.

Who are the male sexual partners of adolescent girls and young women? Comparative analysis of population data in three settings prior to DREAMS roll-out.

BackgroundThe DREAMS (Determined Resilient Empowered AIDS-free, Mentored and Safe) Partnership aims to reduce HIV incidence among adolescent girls and young women (AGYW,15-24y) with a core package of evidence-based interventions. Some interventions, including voluntary HIV counselling and testing and circumcision, will be targeted at the male sexual partners of AGYW. A priority of DREAMS is to characterise the male partners for effective targeting.MethodsUsing population-based data (2010–2015) in three DREAMS impact evaluation settings in Kenya and South Africa, we describe the demographic characteristics and sexual behaviour of male partners reported by AGYW, and the characteristics of males who report sexual activity with AGYW.ResultsIn all settings, over 90% of recent male partners reported by AGYW were aged <35 years. Median ages of spousal and non-spousal partners were 29 and 23 years respectively in uMkhanyakude (rural South Africa) and 21 and 20 years respectively in Nairobi (urban Kenya). Most males reporting an AGYW partner had never been married (89%) and many were in school (39%). Most male partners reported only 1 AGYW partner in the past year; in Gem (rural Kenya) and Nairobi 25%-29% reported 2+(AGYW or older female) partners. Concurrent partners were reported by 16% of male partners in Gem and 3–4% in uMkhanyakude. Two thirds of male partners in Gem reported testing for HIV in the past 6 months and under half in uMkhanyakude reported testing for HIV in the past year. Almost all (96%) partners in Nairobi were circumcised, compared to 45% in Gem and 43% in uMkhanyakude.ConclusionsWith almost all AGYW’s sexual partners aged 15–34 years, this is an appropriate target group for DREAMS interventions. Encouraging young men to reduce their number of partners and concurrency, and uptake prevention and treatment services such as HIV testing, circumcision and ART is crucial in the effort to reduce HIV among both AGYW and young men.

Factors Responsible for Disclosure of HIV Seropositivity among Residents of Cross River State, Nigeria.

Context:Disclosure of HIV-positive status to sex partners is viewed as a preventive measure and as a social and legal responsibility for HIV-infected individuals.Aims:The aim of this study is to determine the proportions and factors responsible for disclosure of HIV seropositivity among residents of Cross River State, Nigeria.Settings and Design:This was a cross-sectional comparative study.Subjects and Methods:It involved 320 HIV-positive individuals equally selected from the urban and rural settings of Cross River State and use questionnaires.Statistical Analysis Used:Data analysis used SPSS version 20.0. Chi-square test and logistic regression were used to identify determinants of HIV status disclosure.Results:Among urban respondents, 93.8% had disclosed compared with 79.4% among rural respondents, the difference was statistically significant (P < 0.001). There was a statistically significant association between HIV status disclosure and age (P = 0.008), marital status (P = 0.027), number of nonspousal sexual partner (P = 0.006), and area of residence (P < 0.001). There was no statistically significant association between HIV status disclosure and gender (P = 0.622), between occupation (P = 0.495) or income (P = 0.351 and head of household (P = 0.241). There was statistically significant association between HIV status disclosure and level of education (P = 0.015), house ownership (P = 0.008), time from diagnosis (P = 0.003), and duration of treatment (P = 0.002).Conclusions:This study has shown that HIV seropositive status disclosure was higher when compared with other local studies, and age, marital status, and area of residence were factors associated with HIV seropositive status disclosure.

Chlamydia trachomatis, Human Immunodeficiency Virus (HIV) Distribution and Sexual Behaviors across Gender and Age Group in an African Setting

ObjectiveThe purpose of this study was to (1) describe the distribution of Chlamydia trachomatis (CT) and Human Immunodeficiency Virus (HIV) cases across gender and age groups in Libreville (Gabon); (2) examine Gabonese Sexually Transmitted Infections (STIs)-related risk behaviour.MethodsThe sampled population was people attending the “Laboratoire National de Santé Plublique”. Between 2007 and 2011, 14 667 and 9 542 people respectively, were tested for CT and HIV infections. 1 854 of them were tested for both infections. We calculated CT and HIV rates across gender and age groups. Also analysed was the groups' contribution to the general CT and HIV epidemiology.STIs-related risk behaviours were assessed in 224 men and 795 women (between July 2011 and March 2013) who agreed and answered a questionnaire including questions on their marital status, number of sex partners, sexual practices, history of STIs, sex frequency and condom use.ResultsData showed a 24% dropped in the CT infection rate between 2007 and 2010, followed by a 14% increase in 2011. The HIV infection rates for the same period were between 15% and 16%. The risk of a CT-positive subject getting HIV is about 0.71 times the risk of a CT-negative subject.Young adult aged between 18 and 35 years old represented 65.2% of people who had STIs. 80% of women and 66% of men confessed to an inconsistent use of condoms. 11.6% of women and 48% of men declared having multiple sex partners. 61% of questioned women and 67% of men declared knowing their HIV status.ConclusionsIn this Gabonese setting, the population-aged from18 to 35 years is the most affected by STIs. Other matters of concern are the inconsistent use of protection and sex with non-spousal or non-life partners.

Association of the ANRS-12126 Male Circumcision Project with HIV Levels among Men in a South African Township: Evaluation of Effectiveness using Cross-sectional Surveys

Randomized controlled trials have shown that voluntary medical male circumcision (VMMC) reduces HIV infection by 50% to 60% in sub-Saharan African populations; however, little is known about the population-level effect of adult male circumcision (MC) as an HIV prevention method. We assessed the effectiveness of VMMC roll-out on the levels of HIV in the South African township of Orange Farm where the first randomized controlled trial (RCT) to test the effect of VMMC on HIV acquisition was conducted in 2002-2005. The Bophelo Pele project is a community-based campaign against HIV, which includes the roll-out of free VMMC. A baseline cross-sectional biomedical survey was conducted in 2007-2008 among a random sample of 1,998 men aged 15 to 49 (survey response rate 80.7%). In 2010-2011, we conducted a follow-up random survey among 3,338 men aged 15 to 49 (survey response rate 79.6%) to evaluate the project. Participants were interviewed, blood samples were collected and tested for HIV and recent HIV infection (using the BED HIV incidence assay), and MC status was assessed through a clinical examination. Data were analyzed using multivariate and propensity statistical methods. Owing to the VMMCs performed in the context of the RCT and the Bophelo Pele project, the prevalence rate of adult MC increased from 0.12 (95% CI 0.10-0.14) to 0.53 (95% CI 0.51-0.55). Without these VMMCs, the HIV prevalence rate in 2010-2011 would have been 19% (95% CI 12%-26%) higher (0.147 instead of 0.123). When comparing circumcised and uncircumcised men, no association of MC status with sexual behavior was detected. Among circumcised and uncircumcised men, the proportion consistently using condoms with non-spousal partners in the past 12 months was 44.0% (95% CI 41.7%-46.5%) versus 45.4% (95% CI 42.2%-48.6%) with weighted prevalence rate ratio (wPRR) = 0.94 (95% CI 0.85-1.03). The proportion having two or more non-spousal partners was 50.4% (95% CI 47.9%-52.9%) versus 44.2% (95% CI 41.3%-46.9%) with wPRR = 1.03 (95% CI 0.95-1.10). We found a reduction of BED-estimated HIV incidence rate ranging from 57% (95% CI 29%-76%) to 61% (95% CI 14%-83%) among circumcised men in comparison with uncircumcised men. Findings suggest that the roll-out of VMMC in Orange Farm is associated with a significant reduction of HIV levels in the community. The main limitation of the study is that it was not randomized and cannot prove a causal association. The roll-out of VMMC among adults in sub-Saharan Africa should be an international priority and needs to be accelerated to effectively combat the spread of HIV.

Male migrants' non-spousal sexual partnerships in the place of origin: an in-depth investigation in two rural settings of India

Male migrants in India are at disproportionately high risk for HIV, not only because of their sexual behaviours in destination areas but also due to their risk behaviours in their place of origin. While studies have documented male migrants' risky behaviours in the home setting, few have attempted to understand the underlying socio-cultural context in which they engage in such behaviours. This paper examines the patterns and context of male migrants' non-spousal sexual partnerships in two high-out-migration districts of India. Data, drawn from a cross-sectional behavioural mixed-methods study conducted in 2008, included a structured survey with 1272 migrants, followed by in-depth interviews with 33 male migrants. Results suggest that sexual activity was common in the place of origin: around 50% of migrants had sex with a non-spousal female partner and two-fifths had initiated sex in this setting. Migrants' non-spousal sexual behaviours in the home village were influenced by the prevailing socio-cultural context, including migrants' enhanced socio-economic status, attitudes to non-spousal sex and accessibility of sexual partners. Male migrants' non-spousal sexual partnerships in source areas are influenced by socio-cultural factors, which must be considered when designing HIV programmes in India and elsewhere.

Symptoms of Sexually Transmitted Infections and Care-Seeking Behaviors of Male Clients of Female Sex Workers in Bangladesh

In Bangladesh, male clients (MCs) of female sex workers (FSWs) represent diverse occupational categories from different socioeconomic strata, and they are considered a bridging group to transmit sexually transmitted infections (STIs) to their spousal and nonspousal female partners. This study aimed to better understand sexual behaviors, STI symptoms, and care-seeking behaviors among MCs of FSWs in Bangladesh. A cross-sectional study was conducted among MCs from November 2005 to July 2006 in 3 types of sex trade settings in Bangladesh. Of 1565 MCs included in this study, 531 were from brothels, 515 from hotels, and 519 from street-based settings. Among the MCs, 32.2% reported having had STI symptoms within the last 1 year before the interview and 81.5% sought care for those symptoms. Among those who reported symptoms, 44.5% received treatment from pharmacies, 37.4% received treatment from qualified medical professionals, 8.6%, received treatment from nongovernment organization clinics, and 7.8% went to herbal providers. Male clients who had only 1 to 4 years of schooling were 2.4 times more likely to have STI symptoms (adjusted odds ratio [OR], 2.4; 95% confidence interval [CI], 1.5-3.8) compared with the MCs having 10 or more years of schooling. The MCs who had sex with more than 3 nonmarital sexual partners in the last month were 2 times more likely to have STI symptoms (adjusted OR, 2.0; 95% CI, 1.4-2.8). The MCs who used condoms consistently in their non-marital sexual contacts were significantly less likely (adjusted OR, 0.4; 95% CI, 0.3-0.6) to have STI symptoms. Reported risk behaviors, STI symptoms and care-seeking behavior suggest that MCs are a potential risk group for transmission of HIV and STIs. The study findings underscore the need to target HIV/STI prevention intervention for MCs, which are predominantly geared toward FSWs.

HIV disease progression compared by linkage status in Rwanda and Zambia

Background Recently HIV infected individuals are followed up at Rwanda-Zambia HIV Research Group (RZHRG) sites to establish markers of disease progression. Here we compare disease progression between seroconverters infected by their spouses (linked transmission) to those infected by non-spousal partners (unlinked transmission) where a greater fraction of individuals are infected by multiple virus variants. Methods Seroconverters (SC) were identified from HIV discordant couples enrolled from the Couples’ VCT program into a prospective cohort study. Linkage of transmission was established by comparing viral DNA sequences in the SC to that of the suspected index partner. SCs were followed up to six years to collect clinical and laboratory data. Data analysis using STATA was done on CD4 and viral load trajectories and a comparison of disease progression with respect to time to endpoints of CD4 <350 cells/uL and initiation of ARVs. Log rank test of equality for survival function was performed for each endpoint and p-values calculated.

Timing and source of subtype-C HIV-1 superinfection in the newly infected partner of Zambian couples with disparate viruses

BackgroundHIV-1 superinfection occurs at varying frequencies in different at risk populations. Though seroincidence is decreased, in the negative partner of HIV-discordant couples after joint testing and counseling in the Zambia Emory HIV Research Project (ZEHRP) cohort, the annual infection rate remains relatively high at 7-8%. Based on sequencing within the gp41 region of each partner's virus, 24% of new infections between 2004 and 2008 were the result of transmission from a non-spousal partner. Since these seroconvertors and their spouses have disparate epidemiologically-unlinked viruses, there is a risk of superinfection within the marriage. We have, therefore, investigated the incidence and viral origin of superinfection in these couples.ResultsSuperinfection was detected by heteroduplex mobility assay (HMA), degenerate base counting of the gp41 sequence, or by phylogenetic analysis of the longitudinal sequences. It was confirmed by full-length env single genome amplification and phylogenetic analysis. In 22 couples (44 individuals), followed for up to five years, three of the newly infected (initially HIV uninfected) partners became superinfected. In each case superinfection occurred during the first 12 months following initial infection of the negative partner, and in each case the superinfecting virus was derived from a non-spousal partner. In addition, one probable case of intra-couple HIV-1 superinfection was observed in a chronically infected partner at the time of his seroconverting spouse's initial viremia. Extensive recombination within the env gene was observed following superinfection.ConclusionsIn this subtype-C discordant couple cohort, superinfection, during the first year after HIV-1 infection of the previously negative partner, occurred at a rate similar to primary infection (13.6% [95% CI 5.2-34.8] vs 7.8% [7.1-8.6]). While limited intra-couple superinfection may in part reflect continued condom usage within couples, this and our lack of detecting newly superinfected individuals after one year of primary infection raise the possibility that immunological resistance to intra-subtype superinfection may develop over time in subtype C infected individuals.

Attitudes and beliefs about anti-retroviral therapy are associated with high risk sexual behaviors among the general population of Kisumu, Kenya

Attitudes and beliefs about antiretroviral therapy (ART) may affect sexual risk behaviors among the general population in sub-Saharan Africa. We performed a cross-sectional population-based study in Kisumu, Kenya to test this hypothesis in October 2006. A total of 1655 participants were interviewed regarding attitudes and beliefs about ART and their sexual risk behaviors. The majority of participants, (71%) men and (70%) women, had heard of ART. Of these, 20% of men and 29% of women believed ART cures HIV. Among women, an attitude that “HIV is more controllable now that ART is available” was associated with sex with a non-spousal partner, increased lifetime number of sexual partners as well as a younger age at sexual debut. No significant associations with this factor were found among men. The belief that “ART cures HIV” was associated with younger age of sexual debut among women. The same belief was associated with an increased likelihood of exchanging sex for money/gifts and decreased likelihood of condom use at last sex among men. These findings were most significant for people aged 15–29 years. In high HIV seroprevalence populations with expanding access to ART, prevention programs must ensure their content counteracts misconceptions of ART in order to reduce high risk sexual behaviors, especially among youth.

The Need to Focus on Sex Workers in Generalized HIV Epidemic Settings

The Need to Focus on Sex Workers in Generalized HIV Epidemic Settings

High prevalence of forced sex among non-brothel based, wine shop centered sex workers in Chennai, India.

Sexual violence has been shown to increase women's risk of HIV infection. India is a country where the HIV epidemic is growing among women and intimate partner violence (IPV) is pervasive. This study examined prevalence of and factors associated with forced sex among female sex workers (FSWs) in Chennai, India. We conducted a probability survey among FSWs in 24 slum venues and identified predictive factors for recent forced sex using univariate and multivariable proportional odds models. Among 522 FSWs, 28% reported having forced sex with one partner and 35% with 2+ partners. In the final multivariable model, women who had a high number of partners who had a strong tendency to drink alcohol before sex were more likely to have experienced forced sex, and women who had both unprotected sex with a nonspousal partner and > 20 days of alcohol consumption in the last 30 days were more likely to have experienced forced sex. Discussion about family violence with larger social networks was independently associated with lower odds of forced sex among FSWs. HIV interventions for FSWs and their clients aimed at reducing alcohol consumption and encouraging condom use could be enhanced by violence prevention interventions to facilitate discourse about sexual violence.

The Use of Qualitative Comparative Analysis for Critical Event Research in Alcohol and HIV in Mumbai, India

In this paper we use Qualitative Comparative Analysis (QCA) in critical event analysis to identify under what conditions alcohol is necessary in contributing to unprotected sex. The paper is based on a set of in-depth interviews with 84 men aged 18 = 29 from three typical low income communities in Mumbai who reported using alcohol and having sex with at least one nonspousal partner once or more in the 30 days prior to the interview. The interviews included narratives of critical events defined as recent (past 30-60 day) events involving sexual behavior with or without alcohol. The paper identifies themes related to alcohol, sexuality and condom use, uses QCA to identify and explain configurations leading to protected and unprotected sex, and explains the differences. The analysis shows that alcohol alone is not sufficient to explain any cases involving unprotected sex but alcohol in combination with partner type and contextual factors does explain unprotected sex for subsets of married and unmarried men.

Spatial Dimensions of Research on Alcohol and Sexual Risk: A Case Example from a Mumbai Study

Alcohol's role in unprotected sex is an important issue in the spread of HIV. Research on alcohol use in many countries has found complex relationships between individual characteristics, places where people drink, and consumption patterns. Data on drinking and leisure time activities and locations from in-person surveys with 1,239 young men aged 18-29 living in low-income communities in Mumbai, India, were analyzed. For every pair of men, an index of association measured the degree of similarity in their reported activities in specific communities. Multidimensional scaling of the similarity matrix revealed men who engaged in similar activities in the same communities. Hierarchical grouping classified men based on their activity dimensions. The ten groups of men, distinguished by their activities in particular communities, also differed in alcohol consumption, number of non-spousal sex partners, and level of unprotected sex. Understanding where activities take place is important in designing venue-based interventions to reduce health risk behaviors leading to the spread of HIV/AIDS.

Migration, Mobility and Sexual Risk Behavior in Mumbai, India: Mobile Men with Non-Residential Wife Show Increased Risk

This paper examines the relationship of migration and mobility of husband and wife to sexual risk behaviors among married men living in economically marginal communities in Mumbai, India. Non-migrant men reported significantly more often than the migrant men that they had one or more sex partners other than their wives in the last year. Further, men with occupational mobility reported significantly more often than the men who were not mobile that they had one or more non-spousal sexual partners in the last 1 year. Married men living in Mumbai with wives residing in their area of origin and who reported occupational mobility had the highest sexual risk behaviors, controlling for socio-demographic characteristics and migration. Interventions aimed at prevention of HIV among men require special focus on both migrant and non-migrant men with greater occupational mobility, with particular emphasis on migrant men whose wives have remained in their pre-migration home areas.

Trends in HIV-Related Behaviors and Knowledge in Uganda, 1989-2005: Evidence of a Shift Toward More Risk-Taking Behaviors

To describe recent trends in HIV-related behaviors and knowledge in Uganda between 1989 and 2005. Population-based, cross-sectional national surveys of adult women and men. Trend analysis of selected HIV-related behavior and knowledge indicators, using data from the 2004-2005 Uganda HIV/AIDS Sero-Behavioral Survey and the 2000-2001, 1995, and 1988-1989 Uganda Demographic and Health Surveys. Responses to similar questions across the different surveys were compared to determine trends in indicators. HIV/AIDS knowledge increased to a high level by 2001 and remained stable thereafter. Some self-reported risk behaviors improved, whereas others deteriorated. Among 15- to 24-year-old women and men, primary abstinence increased, from 23% in 1989 to 32% in 2005 and from 32% in 1995 to 42% in 2005, respectively. In men, there were increases in sex with multiple partners and sex with nonspousal partners, although reported condom use during nonspousal sex declined. Of men aged 15-49 years, self-reported multiple sex partnership increased from 24% in 2001 to 29% in 2005 and nonspousal sex increased from 28% in 2001 to 37% in 2005. Between 2001 and 2005, condom use during last nonspousal sex declined from 65% to 55% in men aged 15-24 years. Although substantial improvements in HIV-related risk behaviors and knowledge occurred since 1989, recent increases in some HIV-related risk behaviors were observed, indicating a shift toward more risk-taking behaviors. Prevention efforts should be reinvigorated to address this, otherwise the past success in the HIV fight will be reversed. Monitoring of HIV-related indicators should be continued.

A combined microfinance and training intervention can reduce HIV risk behaviour in young female participants

To assess effects of a combined microfinance and training intervention on HIV risk behavior among young female participants in rural South Africa. : Secondary analysis of quantitative and qualitative data from a cluster randomized trial, the Intervention with Microfinance for AIDS and Gender Equity study. Eight villages were pair-matched and randomly allocated to receive the intervention. At baseline and after 2 years, HIV risk behavior was assessed among female participants aged 14-35 years. Their responses were compared with women of the same age and poverty group from control villages. Intervention effects were calculated using adjusted risk ratios employing village level summaries. Qualitative data collected during the study explored participants' responses to the intervention including HIV risk behavior. After 2 years of follow-up, when compared with controls, young participants had higher levels of HIV-related communication (adjusted risk ratio 1.46, 95% confidence interval 1.01-2.12), were more likely to have accessed voluntary counseling and testing (adjusted risk ratio 1.64, 95% confidence interval 1.06-2.56), and less likely to have had unprotected sex at last intercourse with a nonspousal partner (adjusted risk ratio 0.76, 95% confidence interval 0.60-0.96). Qualitative data suggest a greater acceptance of intrahousehold communication about HIV and sexuality. Although women noted challenges associated with acceptance of condoms by men, increased confidence and skills associated with participation in the intervention supported their introduction in sexual relationships. In addition to impacts on economic well being, women's empowerment and intimate partner violence, interventions addressing the economic and social vulnerability of women may contribute to reductions in HIV risk behavior.

Between Tradition and Change: Condom Use with Primary Sexual Partners Among Mexican Migrants

The frequency of male Mexico-US migration has been associated with increased HIV risk for sexual partners awaiting their return in Mexico. This study examined the association between sexual partner characteristics and condom use among a sample of 354 male migrants from two Mexican municipalities. Migrants were interviewed about their past year's sex practices. Results indicated that migrants were more likely to use condoms with their non-spousal partners, partners with less education than the migrant, and partners with higher employment status. Condom use was greater among younger migrants and residents of the more densely populated municipality. Findings suggest the coexistence of a traditional cultural orientation that does not support condom use and another one that does provided the sex partner is formally employed. Prevention programs must strengthen the structural conditions fostering greater equality between the sexes and adapt their approaches for different population density, age and partner types.
