Influencing sexual practices among HIV-positive Zambian women

A Systematic Review of Behavioral Couples-Based Interventions Targeting Prevention of Mother-to-Child Transmission in Low- and Middle-Income Countries

There is increasing focus in HIV prevention and treatment on couples-based approaches. No systematic review has synthesized prospective behavioral couples-based HIV trials targeting prevention of mother-to-child transmission (PMTCT) outcomes in low- and middle-income countries (LMICs). We systematically reviewed published abstracts and articles reporting prospective comparative evaluations of behavioral couples-based HIV interventions delivered during pregnancy to both members of a self-identified heterosexual couple in LMICs following PRISMA. Citations, abstracts, and full texts were double screened for eligibility. References meeting eligibility criteria underwent double data abstraction, quality appraisal, and qualitative synthesis. We identified 295 unique publications. Of these, 5 randomized trials were deemed eligible and synthesized. Studies were conducted in 3 different African countries using three overarching intervention approaches: home-based; group workshops; and faith-based. Studies included various PMTCT outcome measures. We found evidence that behavioral couples-based approaches around the time of pregnancy can positively affect HIV testing among pregnant women and their male partners, infant HIV prophylaxis use, and HIV-free infant survival. The effects on other PMTCT outcomes were not well supported. There was a low to moderate risk of bias among the included studies. Few couples-based PMTCT interventions have been tested in LMICs. Of the interventions we located, workshops/group education and home-based couple counseling and testing were most commonly used to promote PMTCT. Research is needed on the role of relationship dynamics within such interventions and whether couples-based approaches during pregnancy can extend to health outcomes across the PMTCT continuum of care.

Interventions to address unequal gender and power relations and improve self-efficacy and empowerment for sexual and reproductive health decision-making for women living with HIV: A systematic review

BACKGROUND

Many women living with HIV experience gendered power inequalities, particularly in their intimate relationships, that prevent them from achieving optimal sexual and reproductive health (SRH) and exercising their rights. We assessed the effectiveness of interventions to improve self-efficacy and empowerment of women living with HIV to make SRH decisions through a systematic review.

METHODS AND FINDINGS

We included peer-reviewed articles indexed in PubMed, PsycINFO, CINAHL, Embase, and Scopus published through January 3, 2017, presenting multi-arm or pre-post intervention evaluations measuring one of the following outcomes: (1) self-efficacy, empowerment, or measures of SRH decision-making ability, (2) SRH behaviors (e.g., condom use, contraceptive use), or (3) SRH outcomes (e.g., sexually transmitted infections [STIs]). Twenty-one studies evaluating 11 intervention approaches met the inclusion criteria. All were conducted in the United States or sub-Saharan Africa. Two high-quality randomized controlled trials (RCTs) showed significant decreases in incident gonorrhea and chlamydia. Sixteen studies measuring condom use generally found moderate increases associated with the intervention, including in higher-quality RCTs. Findings on contraceptive use, condom self-efficacy, and other empowerment measures (e.g., sexual communication, equitable relationship power) were mixed. Studies were limited by small sample sizes, high loss to follow-up, and high reported baseline condom use.

CONCLUSIONS

While more research is needed, the limited existing evidence suggests that these interventions may help support the SRH and rights of women living with HIV. This review particularly highlights the importance of these interventions for preventing STIs, which present a significant health burden for women living with HIV that is rarely addressed holistically. Empowerment-based interventions should be considered as part of a comprehensive package of STI and other SRH services for women living with HIV.

Implementation and assessment of a prevention with positives intervention among people living with HIV at five hospitals in Thailand

BACKGROUND

We implemented a hospital-based prevention with positives (PwP) intervention among people living with HIV (PLHIV) that included HIV transmission risk screening, short HIV prevention messages, family planning, HIV disclosure counseling, and partner HIV testing at five hospitals in Thailand. We assessed changes in sexual risk behaviors among PLHIV who received the PwP services at the hospitals.

METHODS

From January 2008-March 2009, we systematically selected a subset of PLHIV receiving care at the five hospitals to offer participation in the PwP intervention. We collected demographic, risk behavior, and laboratory data using a standardized questionnaire. We analyzed data from PLHIV who completed at least four visits, using generalized estimating equations to identify baseline participant characteristics that were associated with adopting sexual practices less likely to be associated with HIV transmission during follow-up.

RESULTS

A total of 830 PLHIV were interviewed and 756 (91.1%) completed four visits. The median age of these 756 participants was 37 years, 400 (52.9%) were women, and 475 (62.8%) had a steady partner. At baseline, 353 (74.3%) of the steady partners had been tested for HIV and 132 (37.4%) had tested negative. Among the 756 PLHIV, 427 (56.5%) reported having sex in the 3 months before enrollment and 413 (54.6%) in the 3 months before the fourth visit. The proportion reporting having vaginal or anal sex without a condom decreased from 20.8% at baseline to 5.1% at the fourth visit (p<0.001). Factors associated (p<0.05) with abstinence or 100% condom use at follow-up visits included: completing ≥ two visits, being diagnosed with HIV for longer than 3 months, and receiving HIV prevention messages from a doctor (versus a nurse or counselor).

CONCLUSION

Safe sex behaviors increased among PLHIV receiving PwP services, suggesting that expansion of hospital-based PwP services may reduce the number of new HIV infections in Thailand.

Behavioral interventions for improving contraceptive use among women living with HIV

BACKGROUND

Contraception services can help meet the family planning goals of women living with HIV as well as prevent mother-to-child transmission. Due to antiretroviral therapy, survival has improved for people living with HIV, and more HIV-positive women may desire to have a child or another child. Behavioral interventions, involving counseling or education, can help women choose and use an appropriate contraceptive method.

OBJECTIVES

We systematically reviewed studies of behavioral interventions for HIV-positive women intended to inform contraceptive choice, encourage contraceptive use, or promote adherence to a contraceptive regimen.

SEARCH METHODS

Until 2 August 2016, we searched MEDLINE, CENTRAL, Web of Science, POPLINE, ClinicalTrials.gov and ICTRP. For the initial review, we examined reference lists and unpublished project reports, and we contacted investigators in the field.

SELECTION CRITERIA

Studies evaluated a behavioral intervention for improving contraceptive use for family planning (FP). The comparison could have been another behavioral intervention, usual care, or no intervention. We also considered studies that compared HIV-positive versus HIV-negative women. We included non-randomized studies as well as randomized controlled trials (RCTs).Primary outcomes were pregnancy and contraception use, e.g. uptake of a new method or improved use or continuation of current method. Secondary outcomes were knowledge of contraceptive effectiveness and attitude about contraception or a specific contraceptive method.

DATA COLLECTION AND ANALYSIS

Two authors independently extracted the data. One entered the data into RevMan and a second verified accuracy. We evaluated RCTs according to recommended principles. For non-randomized studies, we examined the quality of evidence using the Newcastle-Ottawa Quality Assessment Scale. Given the need to control for confounding factors in non-randomized studies, we used adjusted estimates from the models when available. Where we did not have adjusted analyses, we calculated the odds ratio (OR) with 95% confidence interval (CI). Due to varied study designs and interventions, we did not conduct meta-analysis.

MAIN RESULTS

With three new reports, 10 studies from seven African countries met our eligibility criteria. Eight non-randomized studies included 8980 participants. Two cluster RCTs had 7136 participants across 36 sites. Three studies compared a special FP intervention versus usual care, three examined FP services integrated with HIV services, and four compared outcomes for HIV-positive and HIV-negative women.In four studies with high or moderate quality evidence, the special intervention was associated with contraceptive use or pregnancy. A study from Nigeria compared enhanced versus basic FP services. All sites had integrated FP and HIV services. Women with enhanced services were more likely to use a modern contraceptive method versus women with basic services (OR 2.48, 95% CI 1.31 to 4.72). A cluster RCT conducted in Kenya compared integrated FP and HIV services versus standard referral to a separate FP clinic. Women with integrated services were more likely to use more effective contraception (adjusted OR 1.81, 95% CI 1.24 to 2.63). Another cluster RCT compared an HIV prevention and FP intervention versus usual care in Kenya, Namibia, and Tanzania. Women at the special intervention sites in Tanzania were more likely to use highly effective contraception (adjusted OR 2.25, 95% CI 1.24 to 4.10). They were less likely to report unprotected sex (no condom use) at last intercourse (adjusted OR 0.23, 95% CI 0.14 to 0.40). Across the three countries, women at the special intervention sites were less likely to report any unprotected sex in the past two weeks (adjusted OR 0.56, 95% CI 0.32 to 0.99). A study in Côte d'Ivoire integrated HIV and FP services. HIV-positive women had a lower incidence of undesired pregnancy, but not overall pregnancy, compared with HIV-negative women (1.07 versus 2.38; reported P = 0.023).

AUTHORS' CONCLUSIONS

The studies since 2009 focused on using modern or more effective methods of contraception. In those later reports, training on FP methods and counseling was more common, which may strengthen the intervention and improve the ability to meet clients' needs. The quality of evidence was moderate from the more recent studies and low for those from the 1990s.Comparative research involving contraceptive counseling for HIV-positive women is limited. The FP field needs better ways to help women choose an appropriate contraceptive and continue using that method. Improved counseling methods are especially needed for limited resource settings, such as clinics focusing on people living with HIV.

A cross-sectional study of bacterial vaginosis, intravaginal practices and HIV genital shedding; implications for HIV transmission and women's health

OBJECTIVES

Bacterial vaginosis (BV) is associated with an increased risk of HIV transmission, and intravaginal practices (IVP) are an important risk factor for developing BV. The relationship between IVP, BV and HIV lower genital shedding, responsible for HIV transmission, has not been examined in women receiving antiretrovirals in Zambia.

DESIGN

Cross-sectional study.

SETTING

Community Health Center in Lusaka, Zambia.

PARTICIPANTS AND METHODS

Participants were HIV-infected women receiving antiretroviral therapy and engaging in IVP (n=128). Participants completed audio computer-administered self-interviews to assess IVP and underwent a vaginal examination. BV was diagnosed using Nugent criteria. HIV-1 lower genital shedding was assessed by measuring HIV-1 RNA in cervicovaginal lavages.

RESULTS

Most women engaged in IVP daily (114, 89.0%) and 81 (63.3%) of the participants had BV. HIV-1 genital shedding was detected in 18 (14.2%) participants. BV was associated with daily use of IVP (prevalence ratio, PR=4.58, CI 1.26 to 16.64, p=0.02) and weekly use of traditional medicines for IVP (PR=1.33, CI 1.05 to 1.68, p=0.02). The only factor associated with HIV-1 lower genital shedding was plasma viraemia (PR=4.61, CI 2.02 to 10.54, p<0.001). Neither IVP nor BV were associated with HIV shedding.

CONCLUSIONS

Despite the frequency of IVP and high prevalence of BV, plasma viraemia was the primary factor associated with HIV lower genital shedding. These findings support early initiation of antiretrovirals as an HIV prevention tool. Given adverse health outcomes associated with BV, the association between frequent IVP and BV, and the powerful local norms and traditions encouraging IVP, there is a need for studies assessing culturally tailored interventions to decrease BV in high-prevalence settings.

A Systematic Review of the Effects of Behavioral Counseling on Sexual Risk Behaviors and HIV/STI Prevalence in Low- and Middle-Income Countries

The purpose of this study was to assess the effectiveness of behavioral counseling interventions in reducing sexual risk behaviors and HIV/STI prevalence in low- and middle-income countries. A systematic review of papers published between 1990 and 2011 was conducted, identifying studies that utilized either a multi-arm or pre-post design and presented post-intervention data. Standardized methods of searching and data abstraction were used, and 30 studies met inclusion criteria. Results are summarized by intervention groups: (a) people living with HIV; (b) people who use drugs and alcohol; (c) serodiscordant couples; (d) key populations for HIV prevention; and (e) people at low to moderate HIV risk. Evidence for the effectiveness of behavioral counseling was mixed, with more rigorously designed studies often showing modest or no effects. Recommendations about the use of behavioral counseling in developing countries are made based on study results and in light of the field's movement towards combination prevention programs.

Integrating prevention interventions for people living with HIV into care and treatment programs: a systematic review of the evidence

INTRODUCTION

This review assesses the impact of prevention interventions for people living with HIV on HIV-related mortality, morbidity, retention in care, quality of life, and prevention of ongoing HIV transmission in resource-limited settings (RLSs).

METHODS

We conducted a systematic review of studies reporting the results of prevention interventions for people living with HIV in RLS published between January 2000 and August 2014. Standardized methods of searching and data abstraction were used.

RESULTS

Ninety-two studies met the eligibility criteria: 24 articles related to adherence counseling and support, 13 on risk reduction education and condom provision, 19 on partner HIV testing and counseling, 14 on provision of family planning services, and 22 on assessment and treatment of other sexually transmitted infections. Findings indicate good evidence that adherence counseling and sexually transmitted infection treatment can have a high impact on morbidity, whereas risk reduction education, partner HIV testing and counseling, and family planning counseling can prevent transmission of HIV. More limited evidence was found to support the impact of these interventions on retention in care and quality of life. Most studies did not report cost information, making it difficult to draw conclusions about the cost-effectiveness of these interventions.

CONCLUSIONS

This evidence suggests that these prevention interventions, if brought to sufficient scale and coverage, can help support and optimize the impact of core treatment and prevention interventions in RLS. Further operational research with more rigorous study designs, and ideally with biomarkers and costing information, is needed to determine the best model for providing these interventions in RLS.

Systematic assessment of condom use measurement in evaluation of HIV prevention interventions: need for standardization of measures

When evaluating HIV prevention interventions, condom use is a common outcome measure used to assess changes in HIV-related behaviors; however, no widely accepted standards exist for its measurement. Using systematic review data on HIV prevention interventions conducted in low- and middle-income countries, we examined trends in condom use measurement since 1990. We abstracted data from standardized forms on six dimensions of condom use: partner type, temporal period, measurement scale, consistency, controlling for abstinence, and type of sex. Of 215 studies reviewed, 109 studies (51 %) measured condom use as a primary outcome. Outcomes were stratified by partner type in 47 studies (43 %). Assessing condom use at last sex was the most common measurement. Consistency of condom use was assessed in 47 studies (43 %). Developing and utilizing standards for condom use measurement would increase comparability of findings across studies and benefit HIV prevention research. Recommendations include measuring condom use at last sex, frequency of condom use, and number of protected sex acts in studies evaluating the efficacy of behavioral interventions on sexual risk behavior.

Improving PMTCT uptake in rural South Africa

INTRODUCTION

Despite the widespread availability of prevention of mother-to-child transmission (PMTCT) programs, many women in sub-Saharan Africa do not participate in PMTCT. This pilot study aimed to utilize partner participation in an intervention to support PMTCT uptake.

METHODS

Couples (n ¼ 239) were randomized to receive either a comprehensive couples-based PMTCT intervention or the standard of care.

RESULTS

Compared to the standard of care, participants receiving the intervention increased HIV- and PMTCT-related knowledge (F1,474 ¼ 13.94, p ¼ .004) and uptake of PMTCT, as defined by infant medication dosing (74% vs. 46%, w2 ¼ 4.69, p ¼ .03).

DISCUSSION

Results indicate that increasing male attendance at antenatal clinic visits maybe "necessary but not sufficient" to increase PMTCT uptake. Increasing HIV knowledge of both partners and encouraging active male participation in the PMTCT process through psychoeducational interventions may be a strategy to increase the uptake of PMTCT in South Africa.

Qualitative evaluation of a Positive Prevention training for health care providers in Mozambique

The rapid scale-up of HIV care and treatment in Mozambique has provided an opportunity to reach people living with HIV (PLHIV) with prevention interventions in HIV care and treatment settings. A three-day Positive Prevention (PP) training intervention for health care providers that focused on pressing issues for PLHIV in Mozambique was adapted and delivered at sites in three provinces. In-depth interviews were conducted with 31 providers trained in the PP curriculum. Qualitative data were used to assess the appropriateness of the training materials and approach, which lessons providers learned and were able to implement and which PP messages were still difficult to deliver. Providers reported gaining numerous insights from the training, including how to conduct a risk assessment and client-centered counseling, negotiating disclosure, partner testing, condom use, PMTCT, treatment adherence and approaches for positive living. Training topics not commonly mentioned included discordance counseling, STIs, family planning, alcohol and drug use, and frank sexual risk discussions. While areas for improvement exist, the PP training was useful in transferring skills to providers and is a viable component of HIV care. This evaluation helps identify areas where future PP trainings and specific strategies and messages can be refined for the Mozambican context.

The Impact of Key HIV Intervention Components as Predictors of Sexual Barrier Use: The Zambia Partner Project

Behavioral interventions have utilized a variety of strategies and components to reduce HIV risk. This article describes the partner intervention, a couple-based group HIV risk reduction intervention implemented in 6 urban community health clinics in Lusaka, Zambia, and examines the components of the intervention and their relationship with condom use. Couple members completed assessments on condom use, acceptability, willingness to use condoms, communication, intimate partner violence (IPV), self-efficacy, and HIV information at baseline and 6 months' follow-up. This study examined the relative impact of elements of the intervention as predictors of condom use. Changes in acceptability had the greatest overall influence on condom use, followed by social support, relationship consensus, and willingness to use condoms. Changes in self-efficacy, IPV, negotiation, and information had no influence. Results support the use of multidimensional approaches in behavioral interventions and highlight the importance of identifying critical elements of interventions to maximize risk reduction outcomes.

Effectiveness of a community-based positive prevention intervention for people living with HIV who are not receiving antiretroviral treatment: a prospective cohort study

In Mombasa, Kenya, a community-based HIV risk-reduction intervention effectively reached people living with HIV who were not receiving antiretroviral treatment (ART)—a difficult-to-reach population because they often fall outside the ambit of health care services—and succeeded in reducing reported risky sex behavior and increasing ART uptake.

Background: We report effectiveness of an HIV-prevention intervention delivered by community health workers (CHWs) in Mombasa, Kenya, to PLHIV who have not initiated or who have discontinued ART—an often difficult-to-reach population because they fall outside the ambit of health care and prevention services.

Methods: A 2-arm cohort study assessed a structured risk-reduction intervention involving at least 4 one-to-one counseling sessions and personalized support. The control group received standard prevention services. CHWs recruited treatment-naïve people living with HIV (PLHIV) or those who had previously taken antiretroviral drugs. Data were analyzed using a Propensity Score Matched (PSM)-sample to control for baseline differences between the groups.

Results: 634 PLHIV were recruited and followed for 6 months. Median age was 35 years, and 74.3% were female. Participants in the intervention group reported reduced risky sexual behaviors both at endline compared with baseline and compared with the control group. At endline, in the PSM analysis, participants in the intervention arm were less likely than participants in the control group to report unprotected sex with a spouse (Odds Ratio [OR] = 0.08, 95% confidence interval [CI] = 0.03-0.24), and they reported fewer unprotected sex acts (12.3% versus 46.0%, respectively; OR = 0.16, 95% CI = 0.09-0.29; P<0.001). Further, 92.4% of participants in the intervention group reported zero unsafe sex acts (with partners of negative or unknown HIV status) compared with 70.8% in the control group (P<0.001), and more participants in the intervention arm were receiving ART (34.3% versus 12.7%, respectively; P<0.001).

Conclusion: CHWs effectively reached PLHIV who had never received or who had discontinued ART, and they delivered a risk-reduction intervention that led to declines in reported sexual risk behaviors, as well as to increases in ART uptake. A scaled-up intervention warrants consideration.

Reducing the risk of HIV infection during pregnancy among South African women: a randomized controlled trial

Mpumalanga Province, South Africa has one of the highest HIV/AIDS diagnosis rates among pregnant women (~29.4%). This study sought to enhance male involvement in pregnancy to increase HIV disclosure, sexual communication, HIV knowledge and reduce unprotected sex. Participants attending Antenatal Clinics (ANC) completed HIV counseling and testing and were enrolled with male partners (n=239 couples, 478 individuals). Twelve ANCs were randomly assigned to provide a prevention of mother-to-child transmission (PMTCT) intervention or the standard of care, health education sessions plus PMTCT. Participants were assessed at baseline and post-intervention (approximately 6-8 weeks post-baseline) on demographics, sexual behavior, HIV-related knowledge, and conflict resolution strategies. Experimental participants increased HIV knowledge, use of negotiation, and decreased intimate partner violence. Additionally, they were more likely to have increased condom use from baseline to post-intervention (OR=5.1, 95% CI=[2.0, 13.3]). Seroconversions in the control condition exceeded experimental (6 vs. 0). HIV serostatus disclosure to partner did not increase over time for men or women within the experimental or control condition. Male involvement in pregnancy may be an important strategy to reduce sexual risk behavior and HIV transmission. Results support the utility of group interventions to enhance communication and HIV knowledge among pregnant couples.

HIV knowledge and sexual risk behavior among pregnant couples in South Africa: the PartnerPlus project

In sub-Saharan Africa, 60 % of people living with HIV are women and most are of childbearing age. Alarmingly, seroconversion rates during pregnancy are high and increase as pregnancy progresses, highlighting the importance of increasing HIV-knowledge among pregnant women and their partners. This study compared sexual risk behavior, HIV knowledge and condom use pre- to post-partum among South African couples (n = 239 couples) randomly assigned to an intervention or an enhanced standard of care with the PMTCT protocol at rural community health antenatal clinics. Consistent condom use and HIV-related knowledge increased baseline to post-intervention and was maintained at long term follow up post-partum among participants in the intervention condition. HIV knowledge mediated the relationship between the intervention and consistent condom use. Results from this pilot study provide support for the integration of HIV risk reduction interventions for both women and men into existing PMTCT services during and following pregnancy.

Behavioral interventions for improving contraceptive use among women living with HIV

BACKGROUND

Contraception services can help meet the family planning goals of women living with HIV as well as prevent mother-to-child transmission. Due to the increased availability of antiretroviral therapy, survival has improved for people living with HIV, and more HIV-positive women may desire to have a child or another child. This review examines behavioral interventions to improve contraceptive use, for family planning, among women who are HIV-positive.

OBJECTIVES

We systematically reviewed studies that examined behavioral interventions for HIV-positive women that were intended to inform contraceptive choice, encourage contraceptive use, or promote adherence to a contraceptive regimen.

SEARCH METHODS

Through October 2012, we searched MEDLINE, CENTRAL, POPLINE, EMBASE, CINAHL, PsycINFO, ClinicalTrials.gov and ICTRP. For other relevant papers, we examined reference lists and unpublished project reports, and contacted investigators in the field.

SELECTION CRITERIA

Studies evaluated a behavioral intervention for improving contraceptive use for contraception. The comparison could be another behavioral intervention, usual care, or no intervention. We also considered studies that compared HIV-positive women versus HIV-negative women. We included nonrandomized (observational) studies as well as randomized trials.Primary outcomes were pregnancy and contraception use, e.g., uptake of a new method, improved use or continuation of current method. Secondary outcomes were knowledge of contraceptive effectiveness and attitude about contraception in general or about a specific contraceptive method.

DATA COLLECTION AND ANALYSIS

Two authors independently extracted the data. One author entered the data into RevMan and a second verified accuracy. We examined the quality of evidence using the Newcastle-Ottawa Quality Assessment Scale.Given the need to control for confounding factors in observational studies, we used adjusted estimates from the models when available. Where we did not have adjusted analyses, we calculated the odds ratio (OR) with 95% confidence interval (CI). Due to varied study designs, we did not conduct meta-analysis.

MAIN RESULTS

The seven studies meeting our inclusion criteria had a total of 8882 women. All were conducted in Africa. Three studies compared a special intervention versus standard services. In one, the special intervention site showed greater use of non-condom contraceptives per visit (OR 6.40; 95% CI 5.37 to 7.62) and reported a lower pregnancy incidence. In another study, use of modern contraceptives was more likely for women at sites with enhanced versus basic integrated services (OR 2.48; 95% CI 1.31 to 4.72), but the groups did not differ significantly in change from baseline. In the third study, new use of modern contraceptives, excluding condoms, was less likely for women with integrated services versus those with routine care (OR 0.56; 95% CI 0.42 to 0.75), but new use of condoms was more likely (OR 1.73; 95% CI 1.52 to 1.98).Four older studies compared HIV-positive women versus HIV-negative women. None showed any significant difference between the HIV-status groups in use of modern contraceptives. Two did not provide an intervention for the HIV-negative women. In the larger of the two studies, HIV-positive women were less likely to become pregnant (OR 0.55; 95% CI 0.43 to 0.69). HIV-positive women were more likely to discontinue their hormonal contraceptive (OR 2.52; 95% CI 1.53 to 4.14) but more likely to use condoms (OR 2.82; 95% CI 2.18 to 3.65) and spermicide (OR 2.36; 95% CI 1.69 to 3.30). Two studies provided the intervention to both HIV-status groups. One included many of the women from the study just mentioned, and also showed fewer pregnancies for HIV-positive women (OR 0.39; 95% CI 0.23 to 0.68). In the other study, the HIV-status groups were not significantly different for pregnancy or consistent condom use.

AUTHORS' CONCLUSIONS

Comparative research on contraceptive counseling for HIV-positive women has been limited. We found little innovation in the behavioral interventions. Our ability to make statements about overall results is hampered by varied study designs, interventions, and outcome assessments. The quality of evidence was moderate. Since some of these studies were conducted, improvements in HIV treatment have influenced the fertility intentions of HIV-positive people.The family planning field needs better ways to help women choose an appropriate contraceptive and continue using that chosen method. Women with HIV may have special concerns regarding family planning. Research could focus on assessing the woman's needs and training providers to address those issues rather than delivering standardized information.

Improving sexual health for HIV patients by providing a combination of integrated public health and hospital care services; a one-group pre- and post test intervention comparison

BACKGROUND

Hospital HIV care and public sexual health care (a Sexual Health Care Centre) services were integrated to provide sexual health counselling and sexually transmitted infections (STIs) testing and treatment (sexual health care) to larger numbers of HIV patients. Services, need and usage were assessed using a patient perspective, which is a key factor for the success of service integration.

METHODS

The study design was a one-group pre-test and post-test comparison of 447 HIV-infected heterosexual individuals and men who have sex with men (MSM) attending a hospital-based HIV centre serving the southern region of the Netherlands. The intervention offered comprehensive sexual health care using an integrated care approach. The main outcomes were intervention uptake, patients' pre-test care needs (n=254), and quality rating.

RESULTS

Pre intervention, 43% of the patients wanted to discuss sexual health (51% MSM; 30% heterosexuals). Of these patients, 12% to 35% reported regular coverage, and up to 25% never discussed sexual health topics at their HIV care visits. Of the patients, 24% used our intervention. Usage was higher among patients who previously expressed a need to discuss sexual health. Most patients who used the integrated services were new users of public health services. STIs were detected in 13% of MSM and in none of the heterosexuals. The quality of care was rated good.

CONCLUSIONS

The HIV patients in our study generally considered sexual health important, but the regular counselling and testing at the HIV care visit was insufficient. The integration of public health and hospital services benefited both care sectors and their patients by addressing sexual health questions, detecting STIs, and conducting partner notification. Successful sexual health care uptake requires increased awareness among patients about their care options as well as a cultural shift among care providers.

HIV disclosure, sexual negotiation and male involvement in prevention-of-mother-to-child-transmission in South Africa

HIV-seroconversion during pregnancy is a serious concern throughout South Africa, where an estimated 35 to 40% of pregnant women have HIV/AIDS and drop-out is high at all stages of the prevention-of-mother-to-child-transmission (PMTCT) process. The likelihood of PMTCT success may be linked to partner support, yet male involvement in antenatal care remains low. This qualitative study examined the influence of pregnant couples' expectations, experiences and perceptions on sexual communication and male involvement in PMTCT. A total of 119 couples participated in a comprehensive intervention in 12 antenatal clinics throughout South Africa. Data were collected between December 2010 to June 2011 and analysed using a grounded theory approach. Findings point to the importance of sexual communication as a factor influencing PMTCT male involvement. Analysis of themes lends support to improving communication between couples, encouraging dialogue among men and increasing male involvement in PMTCT to bridge the gap between knowledge and sexual behaviour change.

Secondary HIV prevention: novel intervention approaches to impact populations most at risk

This paper reviews recent secondary prevention interventions designed to reduce sexual risk behaviors among people living with HIV/AIDS (PLWHA). A summary of findings from previous meta-analyses and narrative reviews of interventions is provided. Next, novel HIV prevention approaches for PLWHA are reviewed. The review reports on the efficacy of interventions delivered in primary care settings or by technology-formats, interventions that also address mental health difficulties, and programs to address particular at-risk populations (eg, men who have sex with men). A critique of recent interventions for people living with HIV/AIDS is provided as well as suggestions for future research.

Promoting male involvement to improve PMTCT uptake and reduce antenatal HIV infection: a cluster randomized controlled trial protocol

BACKGROUND

Despite the availability of a dual therapy treatment protocol and infant feeding guidelines designed to prevent mother to child transmission (PMTCT) of HIV, of the over 1 million babies born in South Africa each year, only 70% of those born to HIV positive mothers receive dual therapy. Similar to other resource-poor nations facing the integration of PMTCT into routine pregnancy and infant care, efforts in South Africa to scale up PMTCT and reduce transmission to < 5% have fallen far short of the United Nation's goal of 50% reductions in paediatric HIV by 80% coverage of mothers.

METHODS/DESIGN

This study proposes to evaluate the impact of combining two evidence-based interventions: a couple's risk reduction intervention with an evidence based medication adherence intervention to enhance male participation in combination with improving medication and PMTCT adherence in antenatal clinics to increase PMTCT overall reach and effectiveness. The study will use a group-randomized design, recruiting 240 couples from 12 clinics. Clinics will be randomly assigned to experimental and control conditions and effectiveness of the combined intervention to enhance PMTCT as well as reduce antenatal seroconversion by both individuals and clinics will be examined.

DISCUSSION

Shared intervention elements may decrease sexual risk and enhance PMTCT uptake, e.g., increased male participation, enhanced communication, HIV counselling and testing, adherence, serostatus disclosure, suggest that a combined sexual risk reduction and adherence intervention plus PMTCT can increase male participation, increase couples' communication and encourage adherence to the PMTCT process. The findings will impact public health and will enable the health ministry to formulate policy related to male involvement in PMTCT, which will result in PMTCT.

Behavioral interventions to promote condom use among women living with HIV

BACKGROUND

High rates of HIV infection among women of reproductive age have dramatic consequences for personal and public health. Prophylaxis during sexual intercourse in the form of condoms has been the most effective way to prevent both STI and HIV transmission among people living with HIV.

OBJECTIVES

To investigate the effectiveness of behavioral interventions in promoting condom use among women living with HIV.

SEARCH STRATEGY

We conducted a comprehensive literature search in several scientific databases, clinical trials databases, conference proceedings, and conference websites to identify studies produced between 1980 and May 2010 that met our selection criteria.

SELECTION CRITERIA

Studies were included in the analysis if they conducted a randomized controlled trial that examined the effects of behavioral interventions on condom use among HIV-positive women; considered at least one HIV-related behavioral outcome (e.g., reported protected anal, vaginal, or oral sex) or biological outcome (e.g., acquisition of STIs); and one follow-up assessment three months or more after the intervention. Studies were assessed irregardless of langauge or publication status.

DATA COLLECTION AND ANALYSIS

We used random effects models to summarize odds ratios (ORs) that compared intervention and control groups with respect to a dichotomous outcome (consistent versus inconsistent condom use). We used funnel plots to examine publication bias and a χ(2) statistic to test for heterogeneity. The methodological and evidence quality was evaluated through risk of bias criteria and the GRADE system, respectively.

MAIN RESULTS

Five primary studies that collectively researched a total of 725 women living with HIV were analysed. When compared to standard care or minimal HIV support intervention, meta-analysis showed that behavioral interventions had no effect on increasing condom use among HIV-positive women. This finding was consistent at various follow-up meetings (3, 6, and 12-months) as well as over the entire 12-month follow-up period (OR= 0.82; 95% CI 0.65-1.04; p=0.11). Only one study presented adequate data to analyze the relationship between behavioral interventions and STI incidence. Studies included in this analysis demonstrated low risk of bias based on the risk of bias criteria. However, sample size was considered inadequate across all studies.

AUTHORS' CONCLUSIONS

Meta-analysis shows that behavioral interventions have little effect on increasing condom use among HIV-positive women. However, these findings should be used with caution since results were based on a few small trials that were targeted specifically towards HIV-positive women. To decrease sexual transmission of HIV among this population, we recommend interventions that combine condom promotion, family planning provision and counselling, and efforts to reduce viral loads among HIV-positive women and their partners (e.g., HAART treatment provision). New research is needed to address the needs of HIV-positive women, including an assessment of the impact of interventions that combine safer sexual behavior and harm reduction approaches.

The many faces of translational research: a tale of two studies

Translational research can take many forms: bench to bedside, across cultural groups, across geographical boundaries, among others. This case study will share how we addressed all three "translational" issues using two evidence-based studies (USA, Zambia) to illustrate these "roads less traveled." Our implementation and dissemination efforts were anchored by the "train the trainer" strategy, and the Glasgow RE-AIM model provided programmatic guideposts and direction. Keeping all stakeholders (scientific, community, political) involved in the implementation and dissemination process was an essential, perhaps determining factor in the success of the translation process.

Sexual and reproductive health services for people living with HIV: a systematic review

People living with HIV often have unmet needs for sexual and reproductive health (SRH) services. We present results of a systematic review of studies offering SRH services targeted to people living with HIV. Studies were selected from a broader SRH and HIV linkages review. Inclusion criteria included: (1) peer-reviewed journal articles with a pre-post or multiple-arm study design; (2) reported post-intervention evaluation data; and (3) published 1 January 1990 through 31 December 2007. Nine studies were identified with an average rigour score of 5.1 out of 9. Services included family planning (one study), sexually transmitted infection (STI) services (two studies), combined family planning and STI services (three studies) and multiple services (three studies). The review identified mostly positive effects on the outcomes measured, including condom and contraceptive use and quality of services. Yet gaps remain in the research to establish the best approaches for addressing needs and choices of people living with HIV. There is a need for high-quality intervention studies to determine the most successful and cost-effective strategies for providing SRH services to people living with HIV.

Sexual barrier acceptability among multiethnic HIV-positive and at-risk women

BACKGROUND

Sexual behavior interventions have been found to reduce sexual risk among HIV-seropositive and high-risk HIV-seronegative women.

METHODS

This study examined the influence of ethnicity and HIV serostatus on sexual barrier acceptability and use at short-term and long-term follow-up among African American and Hispanic (n=457) women participating in a gender and culturally tailored sexual risk reduction intervention. We hypothesized that sexual barrier acceptability and use would differ between ethnic groups but that this difference would dissipate after intervention participation. We further postulated that HIV-seropositive women would report greater acceptability and use of sexual barriers than seronegative women at baseline and that after participation in the intervention, acceptability and use would increase for both serostatus groups.

RESULTS

We enrolled 317 African American and 140 Hispanic women, 273 (60%) seropositive and 184 (40%)seronegative. Ethnic differences in the frequency of male and female condom use existed at baseline but were not found at 12-month follow-up. Male condom acceptability was higher among African American women than Hispanic women at baseline and 12-month follow-up. Seropositive women reported higher levels of consistent male condom use, but both ethnic and serostatus groups reported high levels (positive, 40%; negative, 52%) of inconsistent condom use. Most women had little experience with female condoms or lubricating gels and suppositories at baseline. No differences between ethnicities were identified in lubricant use.

CONCLUSIONS

Results support the use of a culturally tailored intervention among these populations to increase sexual barrier use and reduce sexual risk.

Ignoring the group in group-level HIV/AIDS intervention trials: a review of reported design and analytic methods

OBJECTIVES

Studies evaluating the efficacy of HIV/AIDS interventions often involve the random assignment of groups of participants or the treatment of participants in groups. These studies require analytic methods that take within-group correlation into account. We reviewed published studies to determine the extent to which within-group correlation was dealt with properly.

DESIGN

We reviewed group-randomized trials (GRTs) and individually randomized group treatment (IRGT) trials published in HIV/AIDS and general public health journals 2005-2009.

METHODS

At least two of the authors reviewed each article, recording descriptive characteristics, sample size estimation methods, analytic methods, and judgments about whether the methods took intraclass correlation into account properly.

RESULTS

Of those articles including sufficient information to judge whether analytic methods were correct, only 24% used only appropriate methods for dealing with the intraclass correlation. The percentages differed substantially for GRTs (41.7%) and IRGT trials (8.0%). Most of the articles (69.2%) also made no mention of a priori sample size estimation.

CONCLUSION

A majority of the articles in our review reported analyses ignoring the intraclass correlation. This practice may result in underestimated variance, inappropriately small P values, and incorrect conclusions about the effectiveness of interventions. Previous trials that were analyzed incorrectly need to be re-analyzed, and future trials should be designed and analyzed with appropriate methods. Also, journal reviewers and editors need to be aware of the special requirements for design and analysis of GRTs and IRGT trials and judge the quality of articles reporting on such trials according to appropriate standards.

Linking sexual and reproductive health and HIV interventions: a systematic review

BACKGROUND

The international community agrees that the Millennium Development Goals will not be achieved without ensuring universal access to both sexual and reproductive health (SRH) services and HIV/AIDS prevention, treatment, care and support. Recently, there has been increasing awareness and discussion of the possible benefits of linkages between SRH and HIV programmes at the policy, systems and service delivery levels. However, the evidence for the efficacy of these linkages has not been systematically assessed.

METHODS

We conducted a systematic review of the evidence for interventions linking SRH and HIV. Structured methods were employed for searching, screening and data extraction. Studies from 1990 to 2007 reporting pre-post or multi-arm evaluation data from SRH-HIV linkage interventions were included. Study design rigour was scored on a nine-point scale. Unpublished programme reports were gathered as "promising practices".

RESULTS

Of more than 50,000 citations identified, 185 studies were included in the review and 35 were analyzed. These studies had heterogeneous interventions, populations, objectives, study designs, rigour and measured outcomes. SRH-HIV linkage interventions were generally considered beneficial and feasible. The majority of studies showed improvements in all outcomes measured. While there were some mixed results, there were very few negative findings. Generally, positive effects were shown for key outcomes, including HIV incidence, sexually transmitted infection incidence, condom use, contraceptive use, uptake of HIV testing and quality of services. Promising practices (n = 23) tended to evaluate more recent and more comprehensive programmes. Factors promoting effective linkages included stakeholder involvement, capacity building, positive staff attitudes, non-stigmatizing services, and engagement of key populations.

CONCLUSIONS

Existing evidence provides support for linkages, although significant gaps in the literature remain. Policy makers, programme managers and researchers should continue to advocate for, support, implement and rigorously evaluate SRH and HIV linkages at the policy, systems and service levels.

Behavioural interventions for HIV positive prevention in developing countries: a systematic review and meta-analysis

OBJECTIVE

To assess the evidence for a differential effect of positive prevention interventions among individuals infected and not infected with human immunodeficiency virus (HIV) in developing countries, and to assess the effectiveness of interventions targeted specifically at people living with HIV.

METHODS

We conducted a systematic review and meta-analysis of papers on positive prevention behavioural interventions in developing countries published between January 1990 and December 2006. Standardized methods of searching and data abstraction were used. Pooled effect sizes were calculated using random effects models.

FINDINGS

Nineteen studies met the inclusion criteria. In meta-analysis, behavioural interventions had a stronger impact on condom use among HIV-positive (HIV+) individuals (odds ratio, OR: 3.61; 95% confidence interval, CI: 2.61-4.99) than among HIV-negative individuals (OR: 1.32; 95% CI: 0.77-2.26). Interventions specifically targeting HIV+ individuals also showed a positive effect on condom use (OR: 7.84; 95% CI: 2.82-21.79), which was particularly strong among HIV-serodiscordant couples (OR: 67.38; 95% CI: 36.17-125.52). Interventions included in this review were limited both in scope (most were HIV counselling and testing interventions) and in target populations (most were conducted among heterosexual adults or HIV-serodiscordant couples).

CONCLUSION

Current evidence suggests that interventions targeting people living with HIV in developing countries increase condom use, especially among HIV-serodiscordant couples. Comprehensive positive prevention interventions targeting diverse populations and covering a range of intervention modalities are needed to keep HIV+ individuals physically and mentally healthy, prevent transmission of HIV infection and increase the agency and involvement of people living with HIV.

Linking family planning with HIV/AIDS interventions: a systematic review of the evidence

OBJECTIVE

To conduct a systematic review of the literature and examine the effectiveness, optimal circumstances, and best practices for strengthening linkages between family planning and HIV interventions.

DESIGN

Systematic review of peer-reviewed articles and unpublished program reports ('promising practices') evaluating interventions linking family planning and HIV services.

METHODS

Articles were included if they reported post-intervention evaluation results from an intervention linking family planning and HIV services between 1990 and 2007. Systematic methods were used for searching, screening, and data extraction. Quality assessment was conducted using a 9-point rigor scale.

RESULTS

Sixteen studies were included in the analysis (10 peer-reviewed studies and six promising practices). Interventions were categorized into six types: family planning services provided to HIV voluntary counseling and testing (VCT) clients, family planning and VCT services provided to maternal and child health clients, family planning services provided to people living with HIV, community health workers provided family planning and HIV services, VCT provided to family planning clinic clients, and VCT and family planning services provided to women receiving postabortion care. Average study design rigor was low (3.25 out of 9). Most studies reported generally positive or mixed results for key outcomes; no negative results were reported.

CONCLUSION

Interventions linking family planning and HIV services were generally considered feasible and effective, though overall evaluation rigor was low.

Sexual risk reduction among Zambian couples

Zambia has over 1 million HIV infections nationwide and an urban prevalence rate of 23%. This study compared the impact of male involvement in multiple and single session risk reduction interventions among inconsistent condom users in Zambia and the role of serostatus among HIV-seropositive and serodiscordant couples. Couples (N=392) were randomised into intervention arms. Among inconsistent condom users at baseline (N=83), condom use increased in both conditions and this increase was maintained over a 12- month period. At 12 months, seronegative men in the multiple session condition increased sexual barrier (male and female condoms) use in comparison with those in the single session condition (F=16.13, =0.001) while seropositive individuals increased sexual barrier use regardless of condition. Results illustrate the importance of both single and multiple session risk reduction counseling among seronegative men in serodiscordant couples in Zambia, and highlight the differing perception of risk between seropositive and serodiscordant persons.

Secondary prevention of HIV infection: the current state of prevention for positives

PURPOSE OF REVIEW

To provide a state-of-the-science review of the literature on secondary prevention of HIV infection or 'prevention for positives' (PfP) interventions.

RECENT FINDINGS

Early work on PfP focused on understanding the dynamics of risky behavior among People Living with HIV/AIDS (PLWH) and on designing, implementing, and evaluating a limited number of interventions to promote safer sexual and drug use behavior in this population (i.e., PfP interventions). Previous meta-analyses demonstrated that PfP interventions can effectively promote safer behavior. However, the understanding of risk dynamics among PLWH and the extant number and breadth of effective PfP interventions were scant. Recent work has addressed some of these problems, yielding greater understanding of risk dynamics and providing additional, effective interventions. Still, only a modest number of recent, rigorously evaluated, effective interventions have been identified. New ideas for creating stronger, more integrated, and effective PfP interventions have emerged that will guide future intervention research and practice.

SUMMARY

There remains much to be done to understand why, when, and under what conditions PLWH practice risk. Substantial work also needs to be performed to design, implement, rigorously evaluate, and when effective, to disseminate widely, additional, evidence-based PfP interventions targeting diverse populations. Directing such interventions to populations of PLWH at greatest risk for transmission of HIV has the potential to yield significant impact on the pandemic.

Acceptability and use of sexual barrier products and lubricants among HIV-seropositive Zambian men

This study assessed the acceptability and preference for sexual barrier and lubricant products among men in Zambia following trial and long-term use. It also examined the role of men's preferences as facilitators or impediments to product use for HIV transmission reduction within the Zambian context. HIV-seropositive and -serodiscordant couples were recruited from HIV voluntary counseling and testing centers in Lusaka between 2003 and 2006; 66% of those approached agreed to participate. HIV seropositive male participants participated in a product exposure group intervention (n = 155). Participants were provided with male and female condoms and vaginal lubricants (Astroglide [BioFilm, Inc., Vista, CA] & KY gels [Johnson & Johnson, Langhorne, PA], Lubrin suppositories [Kendwood Therapuetics, Fairfield, NJ]) over three sessions; assessments were conducted at baseline, monthly over 6 months and at 12 months. At baseline, the majority of men reported no previous exposure to lubricant products or female condoms and high (79%) levels of consistent male condom use in the last 7 days. Female condom use increased during the intervention, and male condom use increased at 6 months and was maintained over 12 months. The basis for decisions regarding lubricant use following product exposure was most influenced by a preference for communicating with partners; participant preference for lubricant products was distributed between all three products. Results illustrate the importance of development of a variety of products for prevention of HIV transmission and of inclusion of male partners in interventions to increase sexual barrier product use to facilitate barrier acceptability and use in Zambia.

Acceptability of microbicidal surrogates among Zambian women

OBJECTIVES AND GOAL

This study assessed the acceptability after the use of vaginal lubricants as surrogates for microbicides among women in Zambia and the role of cultural factors as facilitators or impediments to their potential use for HIV risk reduction within the Zambian context.

STUDY DESIGN

HIV seronegative women (N = 301) recruited from the University Teaching Hospital HIV Voluntary Counseling and Testing Center were randomized into group, individual, or enhanced usual care arms. Participants attended pre- and post-HIV test counseling, followed by a 3-session, 2-hour once-a-month intervention introducing them to vaginal lubricants (2 types of gels, suppositories) in addition to male and female condoms. Supplies were offered at months 4 and 5; assessments were at baseline, 6, and 12 months.

RESULTS

At baseline, the majority of women reported minimal previous exposure to vaginal products and low levels of condom use. Participants' use of products was influenced by product characteristics and perceived partner acceptability; the majority of participants preferred drier products and suppository delivery systems. The basis for decisions regarding vaginal product acceptability changed over time and followed product exposure, and was greatly influenced by perceptions of partner acceptability.

CONCLUSION

Results illustrate the influence of male partners on Zambian seronegative women's preferences for microbicidal products, and the change in preferred characteristics over time.

Ensuring sexual and reproductive health for people living with HIV: an overview of key human rights, policy and health systems issues

Despite rhetorical attention there is little programmatic guidance as to how best to ensure that women and men living with HIV have access to sexual and reproductive health services that help them realise their reproductive goals, while ensuring their human rights. A dynamic relationship exists between the manner in which health services and programmes are delivered, and the individuals who seek these services. A review of the literature shows clear gaps and highlights areas of concern not yet sufficiently addressed. The delivery and use of health services and programmes is shaped by the underlying determinants of people's access to and use of these services, the health systems in place at community and country level, and the legal and policy environment these systems operate in. Few governments can provide the full range of services that might be required by their populations. In most places, people access health services from a variety of formal and informal providers, and health-related behaviour is influenced from many directions. The synergistic roles of health systems, law and policy and underlying social determinants in helping or hindering the development and delivery of adequate programmes and services for HIV positive people must be addressed.

Sexual Risk Intervention In Multiethnic Drug And Alcohol Users

An estimated 38.6 million persons globally are living with HIV, of whom over 1.1 million reside in Zambia. Of the 2 million cases in the US, 64% of new cases among women are among African Americans. Alcohol and drug use represents a significant risk factor for HIV transmission among both Zambians and African Americans. In addition, gender dynamics in both the US and Zambia promote transmission. This study examines two interventions targeting HIV risk behavior among HIV positive substance users, women in Miami, USA (the New Opportunities for Women (NOW) Project) and men in Lusaka, Zambia (the Partner Project). The study compares the efficacy of these two culturally tailored sexual behavior interventions provided in group and individual session formats. US and Zambian participants increased sexual barrier use and reduced substance-related sexual risk. Comparatively greater gains were made by higher risk Zambian males than US females in both group and individual conditions. Among lower risk participants, women in the group condition achieved and sustained the greatest comparative risk reductions. Results suggest that cost effective group HIV transmission risk reduction interventions for multiethnic individuals can be successfully implemented among both female and male drug and alcohol users in multinational settings.
