The virus stops with me: HIV-infected Ugandans' motivations in preventing HIV transmission

Changing Knowledge and Attitudes Towards HIV Treatment-as-Prevention and "Undetectable = Untransmittable": A Systematic Review

People on HIV treatment with undetectable virus cannot transmit HIV sexually (Undetectable = Untransmittable, U = U). However, the science of treatment-as-prevention (TasP) may not be widely understood by people with and without HIV who could benefit from this information. We systematically reviewed the global literature on knowledge and attitudes related to TasP and interventions providing TasP or U = U information. We included studies of providers, patients, and communities from all regions of the world, published 2008–2020. We screened 885 papers and abstracts and identified 72 for inclusion. Studies in high-income settings reported high awareness of TasP but gaps in knowledge about the likelihood of transmission with undetectable HIV. Greater knowledge was associated with more positive attitudes towards TasP. Extant literature shows low awareness of TasP in Africa where 2 in 3 people with HIV live. The emerging evidence on interventions delivering information on TasP suggests beneficial impacts on knowledge, stigma, HIV testing, and viral suppression.

"We are in this together:" dyadic-level influence and decision-making among HIV serodiscordant couples in Tanzania receiving access to PrEP

BACKGROUND

A substantial number of new HIV infections in sub-Saharan Africa occur within stable couples. Biomedical prevention (pre-exposure prophylaxis, PrEP) and treatment (antiretroviral therapy, ART) can provide benefits to sexual partners and can be used to prevent infection within HIV serodiscordant couples. However, research is typically focused on individuals, not dyads, even when the intervention may directly or indirectly impact sexual partners. Gaps remain in understanding best practices for recruitment, informed consent, and intervention implementation in studies involving HIV prevention and treatment among heterosexual serodiscordant couples. This qualitative study was undertaken to understand and describe decision-making and dyadic-level influence among members of serodiscordant couples regarding (1) participation in a dyadic-based research study involving HIV self-testing and access to PrEP, and (2) utilization of PrEP and ART.

METHODS

This qualitative study was nested within an observational cohort study assessing the acceptability of home-based couples' HIV self-testing and uptake of dyadic care for serodiscordant couples involving facilitated referral for HIV-positive partners and access to PrEP for HIV-negative partners. Semi-structured in-depth interviews were conducted among a subset of study participants (n = 22) as well as individuals involved in serodiscordant relationships who chose not to participate (n = 9). Interviews focused on couples' decision-making regarding study participation and dyadic-level influence on medication use. Interviews were transcribed verbatim and translated from Kiswahili into English. Data were analyzed using thematic analysis.

RESULTS

Three major themes were identified: (1) HIV as "two people's secret" and the elevated role of partner support in serodiscordant relationships; (2) the intersectional role of HIV-status and gender on decision-making; (3) the relational benefits of PrEP, including psychosocial benefits for the couple that extend beyond prevention.

CONCLUSIONS

The study found that couples made joint decisions regarding study participation and uptake of HIV-related medication. Relational autonomy and dyadic-level influence should be considered within research and programs involving HIV serodiscordant couples.

Bridging the Efficacy-Effectiveness Gap in HIV Programs: Lessons From Economics

BACKGROUND

Bridging the efficacy-effectiveness gap in HIV prevention and treatment requires policies that account for human behavior.

SETTING

Worldwide.

METHODS

We conducted a narrative review of the literature on HIV in the field of economics, identified common themes within the literature, and identified lessons for implementation science.

RESULTS

The reviewed studies illustrate how behaviors are shaped by perceived costs and benefits across a wide range of health and nonhealth domains, how structural constraints shape decision-making, how information interventions can still be effective in the epidemic's fourth decade, and how lessons from behavioral economics can be used to improve intervention effectiveness.

CONCLUSION

Economics provides theoretical insights and empirical methods that can guide HIV implementation science.

Role of Family Obligation Stress on Ugandan Women's Participation in Preventive Breast Health

BACKGROUND

The purpose of this study is to determine the role of family obligation stress on Ugandan women's participation in preventive breast health through the receipt of breast cancer education and health check-ups.

MATERIALS AND METHODS

A validated survey was conducted on a community sample of Ugandan women, providing a multi-item scale to assess preventive breast-health-seeking behaviors and measure family obligation stress (FO; range 6-18). Univariate and multivariate linear regression was used to assess associations between sociodemographic factors and FO. Univariate and multivariate linear regression (used in conjunction with the robust sandwich estimator for standard errors) and probability differences (PDs) were used to evaluate associations between preventive breast-health-seeking behaviors, sociodemographic factors, and FO.

RESULTS

A total of 401 Ugandan women ages 25-74 participated in the survey. Most had three or more children in the home (60%) and were employed full time (69%). Higher FO was associated with increasing number of children and/or adults in the household (p < .05), full-time employment (p < .001), and being single (p = .003). Women with higher FO were less likely to participate in breast cancer education (PD = -0.02 per 1-point increase, p = .008) and preventive health check-ups (PD = -0.02, p = .018), associations that persisted on multivariate analysis controlling for sociodemographic factors.

CONCLUSION

Ugandan women with high FO are less likely to participate in preventive breast cancer detection efforts including breast cancer education and preventive health check-ups. Special efforts should be made to reach women with elevated FO, because it may be a risk factor for late-stage presentation among women who develop breast cancer.

IMPLICATIONS FOR PRACTICE

High family obligation stress (FO) significantly reduces women's participation in preventive health check-ups and breast cancer education. These findings support research in U.S. Latinas showing high FO negatively affects women's health, suggesting that FO is an important factor in women's health-seeking behavior in other cultures. Addressing family obligation stress by including family members involved in decision-making is essential for improving breast cancer outcomes in low- and middle-income countries, such as Uganda.

Beyond Risk Compensation: Clusters of Antiretroviral Treatment (ART) Users in Sexual Networks Can Modify the Impact of ART on HIV Incidence

Introduction

Concerns about risk compensation—increased risk behaviours in response to a perception of reduced HIV transmission risk—after the initiation of ART have largely been dispelled in empirical studies, but other changes in sexual networking patterns may still modify the effects of ART on HIV incidence.

Methods

We developed an exploratory mathematical model of HIV transmission that incorporates the possibility of ART clusters, i.e. subsets of the sexual network in which the density of ART patients is much higher than in the rest of the network. Such clusters may emerge as a result of ART homophily—a tendency for ART patients to preferentially form and maintain relationships with other ART patients. We assessed whether ART clusters may affect the impact of ART on HIV incidence, and how the influence of this effect-modifying variable depends on contextual variables such as HIV prevalence, HIV serosorting, coverage of HIV testing and ART, and adherence to ART.

Results

ART homophily can modify the impact of ART on HIV incidence in both directions. In concentrated epidemics and generalized epidemics with moderate HIV prevalence (≈ 10%), ART clusters can enhance the impact of ART on HIV incidence, especially when adherence to ART is poor. In hyperendemic settings (≈ 35% HIV prevalence), ART clusters can reduce the impact of ART on HIV incidence when adherence to ART is high but few people living with HIV (PLWH) have been diagnosed. In all contexts, the effects of ART clusters on HIV epidemic dynamics are distinct from those of HIV serosorting.

Conclusions

Depending on the programmatic and epidemiological context, ART clusters may enhance or reduce the impact of ART on HIV incidence, in contrast to serosorting, which always leads to a lower impact of ART on HIV incidence. ART homophily and the emergence of ART clusters should be measured empirically and incorporated into more refined models used to plan and evaluate ART programmes.

'It is just the way it was in the past before I went to test': a qualitative study to explore responses to HIV prevention counselling in rural Tanzania

Background

Voluntary counselling and testing (VCT) for HIV first evolved in Western settings, with one aim being to promote behaviours which lower the risk of onward transmission or acquisition of HIV. However, although quantitative studies have shown that the impact of VCT on sexual behaviour change has been limited in African settings, there is a lack of qualitative research exploring perceptions of HIV prevention counselling messages, particularly among clients testing HIV-negative. We conducted a qualitative study to explore healthcare worker, community and both HIV-negative and HIV-positive clients’ perceptions of HIV prevention counselling messages in rural Tanzania.

Methods

This study was carried out within the context of an ongoing community HIV cohort study in Kisesa, northwest Tanzania. Nine group sessions incorporating participatory learning and action (PLA) activities were conducted in order to gain general community perspectives of HIV testing and counselling (HTC) services. Thirty in-depth interviews (IDIs) with HIV-negative and HIV-positive service users explored individual perceptions of HIV prevention counselling messages, while five IDIs were carried out with nurses or counsellors offering HTC in order to explore provider perspectives.

Results

Two key themes revolving around socio-cultural and contextual factors emerged in understanding responses to HIV prevention counselling messages. The first included constraints to client-counsellor interactions, which were impeded as a result of difficulties discussing private sexual behaviours during counselling sessions, a hierarchical relationship between healthcare providers and clients, insufficient levels of training and support for counsellors, and client concerns about confidentiality. The second theme related to imbalanced gender-power dynamics, which constrained the extent to which women felt able to control their HIV-related risk.

Conclusion

Within the broader social context of a rural African setting, HIV prevention counselling based on a Western model of individual-level agency seems unlikely to make a significant contribution to sexual behaviour change until there is greater recognition by counsellors of the ways in which power dynamics within many relationships influence behaviour change. More culturally relevant counselling strategies and messages and infrastructural improvements such as additional training for counsellors and counselling rooms which ensure privacy and confidentiality, may lead to better outcomes in terms of sexual risk reduction.

The Missing Men: HIV Treatment Scale-Up and Life Expectancy in Sub-Saharan Africa

In a Perspective accompanying Bor and colleagues, Alexander Tsai and Mark Siedner discuss the gender gap in ART uptake and HIV mortality in Africa.

HIV/AIDS fatalism, beliefs and prevention indicators in Gabon:comparisons between Gabonese and Malians

HIV/AIDS fatalism may impact on individuals' health-seeking behaviour and HIV-prevention efforts. This descriptive study measured levels of HIV/AIDS fatalism and documented HIV/AIDS beliefs and practices among a sample of Gabonese and Malians living in Gabon, West Africa. The Powe Fatalism Inventory-HIV/AIDS version was used to measure levels of fatalism, while a short-answer survey was used to document personal beliefs and behaviours related to HIV and AIDS among 160 people in Gabon. The mean score of HIV/AIDS fatalism for the total sample was 6.8 on a 15-point scale. Malians had a more fatalistic outlook than Gabonese (mean scores 9.4 versus 5.3), Muslims were more fatalistic than persons of other religions (mean scores 9.2 versus 5.3), while healthcare providers were less fatalistic than non-providers (mean scores 3.8 versus 7.4). People that did not believe that HIV/AIDS is a punishment from God had a lower mean score of fatalism than those who did. Most of the sample believed that AIDS is a real disease, and most did not think that only immoral people discuss HIV and AIDS. The HIV-prevention indicators that related to lower scores of fatalism included knowing HIV-positive people, having had more years of formal education, a willingness to disclose one's HIV status (if known), and experience of HIV/AIDS education. Respondents who had tested for HIV were no less fatalistic than those who had never tested. The findings provide data from a part of the world where HIV/AIDS beliefs have rarely been documented. The results indicate a need for additional studies on correlations between HIV/ AIDS fatalism, HIV-prevention behaviours, and religious belief systems.

Characteristics of sexually experienced HIV testers aged 18 to 32 in rural South Africa: baseline results from a community-based trial, NIMH Project Accept (HPTN 043)

BACKGROUND

Young people in South Africa are at high risk of HIV infection and yet may have more limited access to prevention and treatment services than others in the population. Testing facilitates the sharing of prevention messages but also enables the linkage to care and treatment of those who test positive and therefore has wider public health implications.

METHODS

This baseline survey conducted in 2005 for a community randomized trial in rural KwaZulu-Natal explored factors associated with a history of ever, repeat and recent testing amongst sexually debuted men and women aged 18 to 32 years.

RESULTS

Over 35% of this rural population ever tested for HIV, with men less likely to ever (unadjusted OR 0.26, 95% CI: 0.21-0.32) and repeatedly test than women (adjusted OR (aOR) 0.68, 95% CI: 0.48-0.97). Men aged 24-28 years (aOR 2.02, 95% CI: 1.10-3.71) and 29-32 years (aOR 2.69, 95% CI: 1.46-4.94) were more likely to ever test than those <20 years. Those who reported having discussed HIV with others had significantly greater odds of reporting ever (men's aOR 2.83, 95% CI: 1.63-4.89; women's aOR 3.36, 95% CI: 2.50-4.53), recent (irrespective of sex, aOR 2.87, 95% CI: 2.02-4.09) and repeat testing (aOR 2.02, 95% CI: 1.28-3.19).

CONCLUSION

These findings highlight the need for novel youth- and men-friendly testing services and emphasises the importance of discussions about HIV in the home and community to encourage testing.

Social responsibility, substance use, and sexual risk behavior in men who have sex with men

Considerable public health literature focuses on relationships between problematic human characteristics (e.g., psychopathology) and unhealthy behaviors. A recent movement termed positive psychology emphasizes the advantages of assessing relationships between human strengths (e.g., altruism) and beneficial health behaviors. The present study assessed social responsibility, an orientation to help or protect others even when there is nothing to be gained as an individual, and its relationship to HIV-relevant behaviors. In our sample of 350 men who have sex with men (MSM), social responsibility was negatively correlated with substance use and HIV risk behaviors. Men who had been tested for HIV and knew their HIV status-a behavior that helps men protect their partners but does not protect themselves from the virus-also scored higher in social responsibility. Interventions designed to reduce HIV risk behavior in MSM may benefit from efforts to promote human strengths.

How to Understand the Experience of Persons Living with HIV: Implications for Clinical Practice and Research

Sexual behaviour in a rural high HIV prevalence South African community: time trends in the antiretroviral treatment era

Objectives:

Data from generalized epidemic settings have consistently found that patients on antiretroviral therapy (ART) reduce sexual risk behaviours, but how sexual behaviour changes in the general population in response to ART availability, including amongst HIV-uninfected and undiagnosed adults, has not been characterized in these settings.

Design:

General population open cohort.

Methods:

We report trends in sexual behaviour indicators for men aged 17–54 years and women aged 17–49 years in rural KwaZulu-Natal province, based on annual sexual behaviour surveys during ART scale-up from 2005 to 2011. Estimates are adjusted for survey nonparticipation and nonresponse to individual survey items using inverse probability weighting and multiple imputation. Trends are presented by HIV status, knowledge of status, age and marital status.

Results:

Reports of condom use at last sex with a regular partner increased by 2.6% points per year [95% confidence interval (CI) 1.5%, 3.7%] for men and 4.1% per year (3.0%, 5.3%) for women. Condom use at last sex with a casual partner was high and did not change significantly over the period for both sexes. There were statistically significant declines in the percentage reporting multiple partnerships in the last year and the point prevalence of concurrency. Trends within subgroups were generally consistent with overall estimates.

Conclusion:

We find no evidence of increased sexual risk-taking following ART availability and protective changes in some behaviours, suggesting that general trends in sexual behaviour are not counter-acting preventive effects of HIV treatment. Continued monitoring of population-level sexual behaviour indicators will be essential to interpret the success of combination-prevention programmes.

Sexual risk after HIV diagnosis: a comparison of pre-ART individuals with CD4>500 cells/µl and ART-eligible individuals in a HIV treatment and care programme in rural KwaZulu-Natal, South Africa

INTRODUCTION

Little is known about people diagnosed as HIV-positive who access HIV care early in their disease. In pre-ART studies published to date, only a minority of the participants have CD4>500 cells/µl.

METHODS

This cross-sectional study compared individuals presenting for HIV care with CD4>500 cells/µl, "pre-ART" (N=247), with individuals who had CD4<200 cells/µl or WHO Stage IV, "ART-eligible" (N=385). Baseline characteristics were contrasted between the two groups and logistic regression models used to explore group differences in: (a) being sexually active in the last month; (b) disclosure of HIV status to current partner; (c) knowing the HIV status of one's current partner; and (d) condom use at last sex.

RESULTS

Pre-ART and ART-eligible individuals were similar in terms of a wide range of socio-demographic characteristics. Controlling for gender, only current sexual behaviour and HIV-testing history were significantly different between ART groups. In multivariable models, participants in the pre-ART group were twice as likely to be sexually active in the last month, OR 2.06 95% CI (1.32, 3.21), and to know their partner's status, OR 1.95 (1.18, 3.22) compared to those in the ART-eligible group. Self-reported disclosure of HIV status to current sexual partner (71%), condom use at last sex (61%) and HIV concordancy within relationships were not significantly different between the two ART groups. Overall, 39% of the study participants reported knowing that they were in concordant HIV-positive relationships. Fifty-five percent of all participants reported not knowing their partner's HIV status, only half of whom reported using a condom at last sex. Pre-ART individuals were significantly less likely to have tested HIV-positive for the first time in the last year and to have tested for sickness-related reasons than the ART-eligible group.

CONCLUSIONS

Reported sexual risk behaviours by pre-ART individuals with CD4>500 cells/µl suggest a continued risk of onward HIV transmission. There is a need for positive prevention efforts to target this group given that current treatment guidelines do not provide them with ART. Strengthening support regarding disclosure, partner HIV testing and consistent condom use, and further promotion of HIV testing in the community to assist earlier diagnosis are urgently required.

Sexual risk behaviours and barriers to HIV testing among clients of female sex workers in Guatemala: a qualitative study

Few interventions have targeted clients of female sex workers in Central America, despite their potential role in HIV/STI prevention. Semi-structured interviews were conducted with 30 clients of female sex workers on attitudes towards prevention of HIV/STIs, barriers to condom use and behaviour towards HIV/STI testing and treatment in Escuintla, Guatemala. Despite high knowledge of condoms as an HIV/STI preventive measure, the decision to use them was often based on the client's social judgment of the woman's sexual conduct. Regular clients reported lower condom use. Clients' risk perception diminished with the awareness of the public HIV/STI clinic addressed to female sex workers. Most preferred private clinics to increase confidentiality and were reluctant to take the HIV test for fear of a positive result. Outreach programmes offering HIV/STI counselling and testing to clients of female sex workers could increase their test uptake and health-seeking behaviour and reduce potential transmission to the general population.

Sexual behavior of HIV-positive adults not accessing HIV treatment in Mombasa, Kenya: Defining their prevention needs

BACKGROUND

HIV spread continues at high rates from infected persons to their sexual partners. In 2009, an estimated 2.6 million new infections occurred globally. People living with HIV (PLHIV) receiving treatment are in contact with health workers and therefore exposed to prevention messages. By contrast, PLHIV not receiving ART often fall outside the ambit of prevention programs. There is little information on their sexual risk behaviors. This study in Mombasa Kenya therefore explored sexual behaviors of PLHIV not receiving any HIV treatment.

RESULTS

Using modified targeted snowball sampling, 698 PLHIV were recruited through community health workers and HIV-positive peer counsellors. Of the 59.2% sexually-active PLHIV, 24.5% reported multiple sexual partners. Of all sexual partners, 10.2% were HIV negative, while 74.5% were of unknown HIV status. Overall, unprotected sex occurred in 52% of sexual partnerships; notably with 32% of HIV-negative partners and 54% of partners of unknown HIV status in the last 6 months. Multivariate analysis, controlling for intra-client clustering, showed non-disclosure of HIV status (AOR: 2.38, 95%CI: 1.47-3.84, p < 0.001); experiencing moderate levels of perceived stigma (AOR: 2.94, 95%CI: 1.50-5.75, p = 0.002); and believing condoms reduce sexual pleasure (AOR: 2.81, 95%CI: 1.60-4.91, p < 0.001) were independently associated with unsafe sex. Unsafe sex was also higher in those using contraceptive methods other than condoms (AOR: 5.47, 95%CI: 2.57-11.65, p < 0.001); or no method (AOR: 3.99, 95%CI: 2.06-7.75, p < 0.001), compared to condom users.

CONCLUSIONS

High-risk sexual behaviors are common among PLHIV not accessing treatment services, raising the risk of HIV transmission to discordant partners. This population can be identified and reached in the community. Prevention programs need to urgently bring this population into the ambit of prevention and care services. Moreover, beginning HIV treatment earlier might assist in bringing this group into contact with providers and HIV prevention services, and in reducing risk behaviors.

Supporting southern-led research: implications for North-South research partnerships

BACKGROUND

Global health research partnerships are commonly led by Northern investigators who come from resource-rich research environments, while Southern partners participate with a paucity of research skills and resources. This power asymmetry within North-South research partnerships may further exacerbate the unequal distribution of benefits from the research process.

METHODS

This study is designed to present the benefits and challenges of engaging in the research process from the perspective of The AIDS Support Organization (TASO), an HIV/AIDS care and treatment organization that has been involved in global health research partnerships. It uses a validated research tool entitled "Is Research Working for You?" to facilitate qualitative interviews surrounding the experienced benefits and challenges in engaging in the research partnerships as described by TASO staff.

RESULTS

Three key themes emerged from the content and thematic analysis: 1) the reported benefits of research (e.g., evidence-based management, advocacy, etc.), 2) the challenges the research committee members face in becoming more involved in the research process (e.g., lack of data analysis skill, lack of inclusion in the research process, etc.), and 3) the institutional ambition at TASO to develop a Southern-led research agenda.

CONCLUSIONS

This is one of the few studies to document the development of a Southern-led research agenda in addition to the challenges of engaging in the research process. Mechanisms for moderating power dynamics within North-South partnerships can provide opportunities for improved research capacity and quality.

Condoms in sub-Saharan Africa

Sub-Saharan Africa (SSA) is the region with the world’s highest rates of HIV and other sexually transmissible infections (STIs), yet numerous studies show that condom use is generally rare. This suggests a need for a better understanding of how condoms fit within sexual practices and relationships in SSA. This paper seeks to address this need by reviewing research published between the late 1980s and 2011 on use and factors influencing use of male condoms in SSA. What is evident from this research is that condom use involves complex social and interpersonal dynamics, with structural and cultural conditions exerting an influence through framing social cognitions and setting boundaries on autonomy that make the apparently irrational choice of eschewing condoms a rational decision. The influences of poverty; relationships with parents, peers and partners; limited, insufficient or absent information especially in rural areas and among men who have sex with men; gender and sexual norms, and the dynamics of gendered power; and beliefs and attitudes about HIV, condoms and sexuality all have been shown to work against condom use for a large proportion of Africa’s people. However, promising results are shown in trends towards increased condom use among single women in numerous countries, increasing acceptance and use of condoms among some university students, successes in producing potentially sustainable condom use resulting from select interventions, and resistance to succumbing to the dominant gender–power dynamics and structural–cultural impediments that women in groups have mobilised.

Grappling with HIV transmission risks: narratives of rural women in eastern Kenya living with HIV

As people live longer and more productively with HIV infection, issues of agency in reducing HIV risk are particularly important for HIV-infected women living in high prevalence, underresourced countries such as Kenya. Because of their gendered lives, in that being masculine is associated with dominance and being feminine is associated with passiveness, women in rural Kenya must cope with continued HIV transmission risk even after knowing they are infected with HIV. In this narrative interview study, informed by theories of gender and postcolonial feminism, we examined personal accounts of HIV risk and risk reduction of 20 rural women in eastern Kenya who were living with HIV. From our analysis of the women's narratives, two major themes emerged: gender-based obstacles even in the context of a known HIV diagnosis, and struggles with economic pressures amid HIV risks. Implications for policy, programs, and research are discussed.

Sexual behavior of HIV-positive women in Cameroon

This study aimed at describing the sexual behavior of HIV-positive women in Cameroon. In a cross-sectional study, 282 HIV-infected women were enrolled in 3 HIV-treatment clinics in Cameroon. Of the 282 participants, 257 had been diagnosed with HIV for more than 6 months. Approximately half (46.8%) of these 257 women reported no sex partners in the 6 months before the study; 42.9% had 1 partner; and 1.5% had more than 1 partner. There was a significant decrease in the number of partners, new partners, and an increase in condom use with these partners following HIV diagnosis (P value < .05). However, more than half (55.2%) of the sexually active participants reported inconsistent or no condom use during sexual intercourse. Although HIV-positive women tend to adopt less risky behavior after HIV diagnosis, a substantial proportion of sexually active ones still have risky behaviors. Reinforcing risk reduction programs for these women is imperative.

Understanding the context of HIV risk behavior among HIV-positive and HIV-negative female sex workers and male bar clients following antiretroviral therapy rollout in Mombasa, Kenya

This study explored perceptions of HIV following local introduction of antiretroviral therapy (ART), among 30 HIV-positive and -negative female sex workers (FSWs) and 10 male bar patrons in Mombasa, Kenya. Semi-structured interviews were analyzed qualitatively to identify determinants of sexual risk behaviors. ART was not perceived as a barrier to safer sex and in some cases led to decreased high-risk behaviors. Barriers to safer sex included economic pressure and sexual partnership types. Many women reported that negotiating condom use is more difficult in long-term partnerships. These women favored short-term partnerships to minimize risk through consistent condom use. For women living with HIV, concern about maintaining health and avoiding HIV superinfection was a strong motivator of protective behaviors. For HIV-negative women, a negative HIV test was a powerful motivator. Incorporation of context- and serostatus-specific factors (e.g., self-protection for HIV-positive women) into tailored prevention counseling may support high-risk women to reduce risk behaviors.

Change in sexual activity 12 months after ART initiation among HIV-positive Mozambicans

We assessed sexual behaviors before and 12-months after ART initiation among 277 Mozambicans attending an HIV clinic. Measured behaviors included the number of sexual partners, condom use, concurrent relationships, disclosure of HIV status, alcohol use, and partners' serostatus. Compared to before ART initiation, increases were seen 12 months after ART in the proportion of participants who were sexually active (48% vs. 64% respondents, P < 0.001) and the proportion of participants with HIV-negative or unknown serostatus partners (45% vs. 80%, P < 0.001). Almost all (96%) concurrent partnerships reported at 12 months formed after ART initiation. Although reported correct and consist condom use increased, the number of unprotected sexual relationships remained the same (n = 45). Non-disclosure of HIV-serostatus to sexual partners was the only significant predictor of practicing unprotected sex with partners of HIV-negative or unknown serostatus. Sexual activity among HIV-positive persons on ART increased 12 months after ART initiation. Ongoing secondary transmission prevention programs addressing sexual activity with multiple partners, disclosure to partners and consistent condom use with serodisconcordant partners must be incorporated throughout HIV care programs.

Increasing access to HIV counseling and testing through mobile services in Kenya: strategies, utilization, and cost-effectiveness

INTRODUCTION

This study compares client volume, demographics, testing results, and costs of 3 "mobile" HIV counseling and testing (HCT) approaches with existing "stand-alone" HCT in Kenya. A retrospective cohort of 62,173 individuals receiving HCT between May 2005 and April 2006 was analyzed. Mobile HCT approaches assessed were community-site mobile HCT, semimobile container HCT, and fully mobile truck HCT. Data were obtained from project monitoring data, project accounts, and personnel interviews.

RESULTS

Mobile HCT reported a higher proportion of clients with no prior HIV test than stand-alone (88% vs. 58%). Stand-alone HCT reported a higher proportion of couples than mobile HCT (18% vs. 2%) and a higher proportion of discordant couples (12% vs. 4%). The incremental cost-effectiveness of adding mobile HCT to stand-alone services was $14.91 per client tested (vs. $26.75 for stand-alone HCT); $16.58 per previously untested client (vs. $43.69 for stand-alone HCT); and $157.21 per HIV-positive individual identified (vs. $189.14 for stand-alone HCT).

CONCLUSIONS

Adding mobile HCT to existing stand-alone HCT seems to be a cost-effective approach for expanding HCT coverage for reaching different target populations, including women and young people, and for identifying persons with newly diagnosed HIV infection for referral to treatment and care.

Initial outcomes of provider-initiated routine HIV testing and counseling during outpatient care at a rural Ugandan hospital: risky sexual behavior, partner HIV testing, disclosure, and HIV care seeking

Provider-initiated routine HIV testing is being scaled up throughout the world, however, little is known about the outcomes of routine HIV testing on subsequent behavior. This study examined the initial outcomes of provider-initiated routine HIV testing at a rural Ugandan hospital regarding partner HIV testing, sexual risk behavior, disclosure, and HIV care seeking. In a prospective cohort study, 245 outpatients receiving routine HIV testing completed baseline and 3-month follow-up interviews. After receiving routine HIV testing the percentage of participants engaging in risky sex decreased from 70.1% to 50.3% among HIV-negative and from 75.0% to 53.5% among HIV-positive participants, the percentage knowing their partner(s)' HIV status increased from 18.7% to 34.3% of HIV-negative and from 14.3% to 35.7% of HIV-positive participants. Among those reporting risky sex at baseline, HIV-positive participants were more likely to eliminate risky sex in general and specifically to become abstinent at follow-up than were HIV-negative participants. Similarly, unmarried participants who were risky at baseline were more likely to become safe in general, become abstinent, and start 100% condom use than were married/cohabitating participants. Rates of disclosure were high. Over 85% of those who tested HIV positive enrolled in care. Routine HIV testing in this setting may promote earlier HIV diagnosis and access to care but leads to only modest reductions in risky sexual behavior. To fully realize the potential HIV prevention benefits of routine HIV testing an emphasis on tailored risk-reduction counseling may be necessary.
