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

Vaccine value profile for Neisseria gonorrhoeae

Neisseria gonorrhoeae infection (gonorrhoea) is a global public health challenge, causing substantial sexual and reproductive health consequences, such as infertility, pregnancy complications and increased acquisition or transmission of HIV. There is an urgency to controlling gonorrhoea because of increasing antimicrobial resistance to ceftriaxone, the last remaining treatment option, and the potential for gonorrhoea to become untreatable. No licensed gonococcal vaccine is available. Mounting observational evidence suggests that N. meningitidis serogroup B outer membrane vesicle-based vaccines may induce cross-protection against N. gonorrhoeae (estimated 30%-40% effectiveness using the 4CMenB vaccine). Clinical trials to determine the efficacy of the 4CMenB vaccine against N. gonorrhoeae are underway, as are Phase 1/2 studies of a new gonococcal-specific vaccine candidate. Ultimately, a gonococcal vaccine must be accessible, affordable and equitably dispensed, given that those most affected by gonorrhoea are also those who may be most disadvantaged in our societies, and most cases are in less-resourced settings. This vaccine value profile (VVP) provides a high level, holistic assessment of the current data to inform the potential public health, economic and societal value of pipeline vaccines. This was developed by a working group of subject matter experts from academia, non-profit organizations, public private partnerships and multi-lateral organizations. All contributors have extensive expertise on various elements of the N. gonorrhoeae VVP and collectively aimed to identify current research and knowledge gaps. The VVP was developed using published data obtained from peer-reviewed journals or reports.

The Evidence Project: Protocol for Systematic Reviews of Behavioral Interventions and Behavioral Aspects of Biomedical Interventions for HIV Prevention, Treatment, and Health Service Delivery in Low- and Middle-Income Countries

The Evidence Project conducts systematic reviews and meta-analyses of HIV behavioral interventions, behavioral aspects of biomedical interventions, combination prevention strategies, modes of service delivery, and integrated programs in low- and middle-income countries. Here, we present the overall protocol for our reviews. For each topic, we conduct a comprehensive search of five online databases, complemented by secondary reference searching. Articles are included if they are published in peer-reviewed journals and present pre/post or multi-arm data on outcomes of interest. Data are extracted from each included article by two trained coders working independently using standardized coding forms, with differences resolved by consensus. Risk of bias is assessed with the Evidence Project tool. Data are synthesized descriptively, and meta-analysis is conducted when there are similarly measured outcomes across studies. For over 20 years, this approach has allowed us to synthesize literature on the effectiveness of interventions and contribute to the global HIV response.

Effectiveness of trauma-focused cognitive behavioral therapy compared to psychosocial counseling in reducing HIV risk behaviors, substance use, and mental health problems among orphans and vulnerable children in Zambia: a community-based randomized controlled trial

Orphans and vulnerable children (OVC) in sub-Saharan Africa are at high risk for HIV infection and transmission. HIV prevention and treatment efforts with OVC are hindered by mental health and substance use problems. This randomized controlled trial compared a mental health intervention, Trauma Focused Cognitive Behavioral Therapy (TF-CBT), to an enhanced version of an existing HIV Psychosocial Counseling (PC+) program among 610 adolescents who met PEPFAR criteria for OVC and had HIV risk behaviors in Lusaka, Zambia. Outcomes included HIV risk behaviors (e.g., risky sexual behaviors), mental health (internalizing symptoms, externalizing behaviors, PTSD) and substance use. At 12-month follow-up, there were significant within group reductions in both groups for all outcomes, with the only significant between group difference being for substance use, in which OVC who received TF-CBT had significantly greater reductions than OVC who received PC+. In a subgroup analysis of OVC with high levels of PTSD symptoms, TF-CBT was superior to PC + in reducing internalizing symptoms, functional impairment, and substance use. Findings support TF-CBT for reducing substance use among OVC. Subgroup analysis results suggest that a robust intervention such as TF-CBT is warranted for OVC with significant mental and behavioral health comorbidities. The similar performance of TF-CBT and PC + in the overall sample for risky sexual behavior and mild mental health problems indicates that enhancing existing psychosocial programs, such as PC, with standard implementation factors like having a defined training and supervision schedule (as was done to create PC+) may improve the efficacy of HIV risk reduction efforts.Clinical Trials Number: NCT02054780.

A Challenging Knowledge Gap: Estimating Modes of HIV Acquisition Among Adolescents Entering HIV Care During Adolescence

Characterizing HIV acquisition modes among adolescents with HIV (AHIV) enrolling in care during adolescence is a challenging gap that impacts differential interventions. We explored whether primary data collection with targeted questionnaires may address this gap and improve understanding of risk factors and perceptions about adolescents’ HIV acquisition, in Kenyan AHIV entering care at ≥10 years, and their mothers with HIV (MHIV). Clinical data were derived through chart review. Among 1073 AHIV in care, only 26 (2%) met eligibility criteria of being ≥10 years at care enrollment, disclosed to, and with living MHIV. Among 18/26 AHIV-MHIV dyads enrolled (median age of AHIV 14 years), none had documented HIV acquisition modes. Data suggested perinatal infection in 17/18 AHIV, with 1 reported non-perinatal acquisition risk factor, and some discordance between adolescent-mother perceptions of HIV acquisition. In this difficult-to-enroll, vulnerable population of AHIV-MHIV dyads, primary data collection can enhance understanding of AHIV acquisition modes.

Trends of HIV/AIDS knowledge and attitudes among Nigerian women between 2007 and 2017 using Multiple Indicator Cluster Survey data

BACKGROUND

Globally, Nigeria ranks third among the countries with the highest number of People Living with HIV (PLHIV). Given that HIV/AIDS knowledge is a key factor that determines the risk of transmission and certain attitudes towards PLHIV, there is a need to understand the trend of HIV knowledge within the population for the purpose of assessing the progress and outcome of HIV prevention strategies. The aim of the study was to understand the trends of HIV/AIDS knowledge and attitude towards PLHIV between 2007 to 2017 among Nigerian women, and to investigate change in the factors associated with HIV/AIDS knowledge and attitude towards PLHIV over years.

METHODS

Data were derived from three Nigerian Multiple Indicator Cluster Surveys (2007, 2011 and 2016-2017) among women aged 15-49 years old from each geo-political zone (South South, South East, South West, North East, North West, North Central) in Nigeria. Participants who did not answer questions related to HIV/AIDS knowledge and attitude were excluded from the study. The final sample sizes were 17,733 for 2007, 26,532 for 2011 and 23,530 for 2017. In descriptive statistics, frequencies represented the study sample, while percentages represented weighted estimates for the population parameters. Rao-Scott chi-square test for complex survey design studies was used to assess bivariable associations. Factors associated with outcome variables were examined using the survey-weighted multivariable logistic regression models for the complex survey design while controlling for potential confounding variables.

RESULTS

There was a relatively high level of HIV/AIDS knowledge level in 2007 and 2016-2017 surveys (64.6 and 64.1%, respectively), however a decrease in HIV/AIDS knowledge trend was observed in 2011 (45.6%). The positive attitude towards PLHIV progressively increased across the years (from 40.5 to 47.0% to 53.5%). Multivariable analysis revealed that women who had a higher educational level, higher wealth index, and lived in urban areas had higher odds for HIV/AIDS knowledge and positive attitude towards PLHIV across the years. In addition, the Northern zones had predominantly higher knowledge and attitude levels.

CONCLUSIONS

Our study found increasing tendency for high HIV/AIDS knowledge and positive attitude towards PLHIV over the years. Women's age, wealth index, education level and residence were consistently associated with knowledge and attitude over the years. There is a need for more pragmatic HIV/AIDS-related knowledge action plan to target to cover all age groups, all geo-political zones while paying close attention to the rural areas and the less educated women. In addition, more replicative studies of HIV/AIDS knowledge and attitude trends is crucial in monitoring of the progress of HIV interventions in the country in the coming years.

Provider attitudes towards a brief behavioral intervention for sexual health in Moldova

Background

Brief behavioral interventions are seen as an efficient way to improve knowledge, change behavior, and reduce provider stigma regarding sexual health. When grounded in evidence-based behavioral change techniques and delivered using Brief Sexuality-related Communication (BSC) tools, brief behavioral interventions can address client-driven sexual health goals in a single session with their provider. Evidence for the efficacy of brief interventions for creating gains in sexual health comes largely from resource rich settings, and there is a lack of knowledge of how brief interventions can be implemented in the more resource constrained environments of low- and middle-income countries. As a first step in developing a brief intervention to address sexual health issues in Moldova, this paper reports on qualitative data collected from Moldovan providers to understand their attitudes, willingness and perceived barriers to the brief intervention and its implementation.

Methods

Thirty-nine in-depth interviews (IDI) were conducted between February and March 2020, with health providers recruited from three primary health care institutions, two Youth Friendly Health Centers and counselors from three NGOs who work with key populations in Moldova, including health centers selected from two cites - the capital city, Chisinau and from the Comrat Region. The IDI addressed four domains of provider attitudes: 1) attitudes towards the intervention; 2) willingness and motivation to implement the intervention; 3) logistics of providing the intervention and 4) ability to implement the intervention. A coding analysis approach was applied to all interview transcripts.

Results

Providers largely reported being willing to be trained in and implement the brief intervention. Willingness to implement the intervention stemmed from two perceptions: that it would improve the ability of providers to talk with their clients about sex, and that vulnerable groups would benefit from these conversations. However, while there were generally positive attitudes towards the intervention, providers consistently reported structural barriers to their perceived ability to implement the intervention.

Conclusions

While providers reported high levels of initial acceptance of a brief behavioral intervention, care is needed to ensure that brief interventions, and the training of providers on brief interventions, incorporate cultural attitudes and norms around sex, particularly in highly patriarchal settings, and provide opportunities for providers to practice the intervention in ways that address their assumptions and implicit biases.

Couples' decision-making on post-partum family planning and antenatal counselling in Uganda: A qualitative study

BACKGROUND

Although health workers have been trained to provide post-partum family planning (PPFP), uptake remains low in Uganda. An important reason is that women want the agreement of their partner, who is often absent at the time of delivery. In order to address this, we aimed to understand the views of couples and explore barriers and facilitators to implementation of antenatal couples' counselling on PPFP in Uganda.

METHODS

We conducted individual interviews with a purposive sample of 12 postpartum and 3 antenatal couples; and 34 focus groups with a total of 323 participants (68 adolescent women, 83 women aged 20-49, 79 men, 93 health workers) in four contrasting communities (urban and rural) in South-West and Central Uganda. These were recorded, transcribed, translated, and analysed thematically.

RESULTS

Although most participants felt that it is important for partners to discuss family planning, half of the couples were unaware of each other's views on contraception. Most had similar views on motivation to use family planning but not on preferred contraceptive methods. Most liked the idea of antenatal couples' counselling on PPFP. The main barrier was the reluctance of men to attend antenatal clinics (ANC) in health facilities. Respondents felt that Village Health Teams (VHTs) could provide initial counselling on PPFP in couples' homes (with telephone support from health workers, if needed) and encourage men to attend ANC. Suggested facilitators for men to attend ANC included health workers being more welcoming, holding ANC clinics at weekends and "outreach" clinics (in rural villages far from health facilities).

CONCLUSION

Antenatal couples' counselling has the potential to facilitate agreement PPFP, but some men are reluctant to attend antenatal clinics. Counselling at home by VHTs as well as simple changes to the organisation of antenatal clinics, could make it possible to deliver antenatal couples' counselling on PPFP.

Implementing Couple's Human Immunodeficiency Virus Testing and Counseling in the Antenatal Care Setting

OBJECTIVE

To describe a pilot implementation of couple's human immunodeficiency virus (HIV) testing and counseling in an antenatal care clinic in the United States.

METHODS

We used a cross-sectional study design. Couples were recruited from an antenatal care clinic of a large, urban, tertiary medical center, and were eligible if both partners agreed to receive HIV test results together and reported no coercion to participate in testing and counseling and no intimate partner violence. We assessed relationship characteristics, HIV risk-related behaviors and concordance of couples' sexual agreement (ie, mutual agreement about sexual risk behaviors that are permissible within or outside of their relationship). Acceptability of couple's HIV testing and counseling (ie, format, quality of the sessions, ability to meet their needs) was assessed after completing the session. Barriers and facilitators to couple's HIV testing and counseling were assessed at the individual-level among decliners and participants and at the clinic-level among members of the care team.

RESULTS

Dyadic data were collected from 82 individuals (41 couples). Most partners (n=56, 68%) did not have a sexual agreement or had differing expectations about their sexual agreement. Partners with a concordant sexual agreement (n=26) felt more confident working with their partners on condom use when having sex outside of their relationship (P=.008) and were more likely to agree with their partner to get tested regularly for HIV or sexually transmitted infections (P=.015). Acceptability was high, with a rating of 93 or more (out of 100) among all items. Individual-level barriers to couple's HIV testing and counseling included difficulty bringing the male partner for counseling and a perception by either member of the couple that they were at low-risk for HIV. At the clinic level, need for training, staff turnover, and integration of couple's HIV testing and counseling in the clinic flow presented as barriers, whereas commitment by the clinic leadership facilitated the couple's HIV testing and counseling program.

CONCLUSION

Despite barriers, couple's HIV testing and counseling can be implemented in antenatal clinics and is a highly acceptable method of HIV testing.

Decision making over condom use during menses to avert sexually transmissible infections

Background The aim of this study was to test the hypothesis that receptive partners in penile-vaginal intercourse (PVI) who exercise independent decision making over condom use during menses do so to avert sexually transmissible infection (STI) transmission or acquisition.

METHODS

Data were collected through a partnership with Clue, the industry-leading female health app. A brief web-based questionnaire was developed, translated into 10 languages, and made accessible via a URL link sent to Clue users and posted on social media. Inclusion criteria were: age ≥14 years, not being currently pregnant and engaging in PVI and condom use during menses in the past 3 months. The analytical subsample comprised 12889 respondents residing in 146 countries.

RESULTS

Twenty per cent indicated independent decision making about condom use during menses. Independent decision making was associated with lower odds of reporting that condoms were used for contraception (adjusted odds ratio (aOR) 0.65; 99% confidence interval (CI) 0.57-0.73) and higher odds that they were used for the prevention of STIs (aOR 1.44; 99% CI 1.28-1.61). A third significant finding pertained to always using condoms during menses; this was less likely among those indicating independent (female only) decision making (aOR 0.69; 99% CI 0.62-0.78). Non-significant associations with another two outcomes were found: protecting the partner against menstrual blood and protecting themselves against semen.

CONCLUSIONS

Findings from people in 146 countries strongly support the hypothesis that those exercising independent decision making over condom use during menses do so to avert STI transmission or acquisition. That only one-fifth of this global sample reported this type of independent decision making suggests that empowerment-oriented (structural-level) interventions may be advantageous for individuals who are the receptive partner in PVI that occurs during menses.

Perceived Knowledge of HIV-Negative Status Increases Condom Use Among Female Sex Workers in Zambian Transit Towns

Knowledge of HIV status is a necessary pre-condition for most HIV interventions, including treatment as well as biomedical and behavioral prevention interventions. We used data from a female sex worker (FSW) cohort in three Zambian transit towns to understand the effect that knowledge of HIV status has on FSWs' HIV risk-related sexual behaviors with clients. The cohort was formed from an HIV self-testing trial that followed participants for 4 months. Participants completed three rounds of data collection at baseline, 1 month, and 4 months where they reported their perceived knowledge of HIV status, number of clients on an average working night, and consistent condom use with clients. We measured the effect of knowledge of HIV status on participants' sexual behaviors by using linear regression models with individual fixed effects. The majority of the 965 participants tested for HIV at least once during the observation period (96%) and changed their knowledge of HIV status (79%). Knowledge of HIV status did not affect participants' number of clients, but it did affect their consistency of condom use. Compared with unknown HIV status, knowledge of HIV-negative status significantly increased participants' consistent condom use by 8.1% points [95% confidence interval (CI): 2.7–13.4, p = 0.003] and knowledge of HIV-positive status increased participants' consistent condom use by 6.1% points (95% CI: −0.1 to 12.9, p = 0.08); however, this latter effect was not statistically significant. FSWs in Zambia engaged in safer sex with clients when they learned their HIV status. The expansion of HIV testing programs may serve as a behavioral HIV prevention measure among FSWs.

Errors in Condom Use in the Setting of HIV Transmission: A Systematic Review

Background:

The efficacy of condom use in declining HIV transmission may be compromised by their incorrect usage. Much focus has been paid on the regularity of condom usage but consumer mistakes and challenges must be considered. Breakage, slipping, leakage, incomplete use and other problems during the sexual event may compromise the protective role of the condom.

Objective:

To evaluate through a systematic review of published data, the type, and incidence of error and problems in condom use, and their possible role in reducing the preventive action of condoms.

Methods:

A systematic literature search for peer-reviewed articles published between January 2000 and January 2019, issued in English in peer-reviewed journals, and reporting the occurrence of condom errors/problems among HIV high-risk populations.

Results:

Twenty studies representing nine countries met the inclusion criteria. The most predominant mistakes associated with condom use included condom breakage, slippage, delayed condom application, early removal, issues related to erection loss and difficulties with fit and feel were reported, failure to squeeze out air, use of expired condoms, reuse of condom, and wearing the condom outside out were other issues noticed.

Conclusions:

Condom use problems and mistakes are prevalent across the globe. Educational efforts are needed to empower HIV the at-risk population with confidence and knowledge to improve correct condom use and increase preventive activity

"It was my obligation as mother": 18-Month completion of Early Infant Diagnosis as identity control for mothers living with HIV in Kenya

RATIONALE

Early Infant Diagnosis (EID) is critical to timely identification of HIV and rapid treatment initiation for infants found to be infected. Completing the EID cascade involves a series of age-specific tests between birth and 18 months and can be challenging for mother- infant pairs in low-resource settings. Even prior to recent increases in Kenya's testing recommendations, approximately 22% of mother-infant pairs enrolled in EID were lost to follow-up. As EID cascades become increasingly complex, identifying strategies to maximize retention becomes even more essential. Despite ongoing health system improvements, we still lack a framework for understanding the individual-level, psychosocial processes underlying EID completion-insight that could be essential for shaping strategies to support patients and close gaps in retention.

OBJECTIVE

Our objective was to explain individual-level processes that lead to EID completion among mothers who successfully completed the EID cascade.

METHODS

Using qualitative methods informed by grounded theory, we conducted 65 interviews with Kenyan mothers who completed EID.

RESULTS

We identified three themes related to completion: (1) Negative motivation, from the consequences of infant infection, fear of postnatal transmission, and burden of maternal failure; (2) Positive motivation, from achieving a final goal, responding to provider support, and maximizing infant health; and (3) Overcoming challenges, through resolve/resiliency, planning/privatizing and rejecting stigma/leveraging support.

CONCLUSION

Overall, the EID cascade served as a framing process for women to secure an identity as a good mother. Successful EID completion was the product of a strong motivational foundation channeled into strategies to surmount persistent challenges. Participant accounts of overcoming challenges highlight their resiliency as well as the outstanding need to address financial, logistical, and social barriers to care. Future EID programs may capitalize on these findings by affirming patients' quest for identity control, leveraging positive motivators, and expanding peer support structures to help mothers feel connected throughout the cascade.

Inconsistent condom use between serodifferent sexual partnerships to the human immunodeficiency virus

Objective:

to analyze predictors of inconsistent condom use among HIV-positive people with sexual immunodeficiency virus serodifferent sexual partnership.

Method:

cross-sectional, analytical study with a consecutive non-probabilistic sample consisting of people living with the human immunodeficiency virus with serodifferent sexual partnership and who were in outpatient clinical follow-up. Data were collected through individual interviews guided by a semi-structured questionnaire and subsequently analyzed with bivariate analysis and logistic regression.

Results:

Seven variables were independently associated with inconsistent condom use. Schooling less than 11 years of schooling (4.9 [2.4-10.1]), having multiple partnerships (5.0 [1.3-19.6]), using alcohol (2.1 [1.1 -4.4]) or other drugs (2.8 [1.2-6.3]), do not receive advice from a healthcare professional (2.0 [1.1-3.9]), have no knowledge of treatment as prevention (3.0 [1,2-6,9]) and not knowing that undetectable viral load reduces the risk of human immunodeficiency virus transmission (3.8 [1,1-13,7]) were predictors for inconsistent condom use.

Conclusion:

The study showed that psychosocial factors interfere with consistent condom use between serodifferent partnerships. Thus, it is highlighted that there is a need for comprehensive interventions that include the integration of clinical and psychosocial care.

Computer-Based Counseling Program (CARE+ Kenya) to Promote Prevention and HIV Health for People Living With HIV/AIDS: A Randomized Controlled Trial

In countries experiencing the dual burden of HIV disease and health care worker shortages, information and communication technology tools offer the potential to help support HIV treatment adherence and secondary HIV transmission risk reduction for people living with HIV/AIDS. We conducted a randomized controlled trial (September 1, 2011-July 12, 2012) with follow-up through April 2013. Participants were recruited from two clinics affiliated with the Academic Model Providing Access to Healthcare program in western Kenya. A total of 236 participants were enrolled, randomly assigned to intervention (n = 118) or risk-assessment only control (n = 118) and followed up for 9 months. Both arms had > 0.5 log10 reduction in viral load over time (p = .0007), a clinically relevant finding. A computer-based counseling tool is feasible and acceptable in a high-volume East African HIV setting and provides evidence-based ART adherence and risk reduction support that may extend health workforce deficits.

HIV voluntary counselling and testing and behaviour changes among youths in Nigeria

Voluntary counselling and testing (VCT) for HIV has been promoted as a strategy to prevent HIV pandemics by changing sexual behaviour. Despite the provision of VCT in countries with generalized or high-burden epidemics, including Nigeria, the extent of its influence on behavioural change remains a conjecture. The main objective of this study was to examine the influence of HIV VCT on sexual behaviour changes among youths in Nigeria. The study utilized 2013 Nigeria Demographic and Health Survey (NDHS) data. Data were analysed from a nationally representative sample drawn from 8046 females and 6031 males aged 15-24 giving a total sample of 14,077 never-married youths. Descriptive and analytical analyses were carried out, including multivariate logistic regression. The study found a low uptake of HIV VCT and regional variation in behavioural changes between female and male youths. Voluntary HIV counselling and testing was found to be a protective factor for condom use at last sex for female youths, but significantly reduced the likelihood of primary sexual abstinence for both females and males, as well as having a single sexual partner for female youths. After controlling HIV VCT with other variables, certain socioeconomic factors were found to be significantly associated with behavioural changes. Thus, the attitudes of most Nigerian youths towards voluntary HIV counselling and testing needs to be improved through socioeconomic factors for healthy sexual activity. To achieve this, government and non-governmental organizations, as well as religious leaders and policymakers, should engage in appropriate and long-term activities directed at the sexual health needs of never-married youths, through voluntary HIV counselling and testing, to encourage them to change their sexual behaviour.

Is knowledge of HIV status associated with sexual behaviours? A fixed effects analysis of a female sex worker cohort in urban Uganda

INTRODUCTION

Female sex workers (FSWs) have strong economic incentives for sexual risk-taking behaviour. We test whether knowledge of HIV status affects such behaviours among FSWs.

METHODS

We used longitudinal data from a FSW cohort in urban Uganda, which was formed as part of an HIV self-testing trial with four months of follow-up. Participants reported perceived knowledge of HIV status, number of clients per average working night, and consistent condom use with clients at baseline, one month, and four months. We measured the association between knowledge of HIV status and FSWs' sexual behaviours using linear panel regressions with individual fixed effects, controlling for study round and calendar time.

RESULTS

Most of the 960 participants tested for HIV during the observation period (95%) and experienced a change in knowledge of HIV status (71%). Knowledge of HIV status did not affect participants' number of clients but did affect their consistent condom use. After controlling for individual fixed effects, study round and calendar month, knowledge of HIV-negative status was associated with a significant increase in consistent condom use by 9.5 percentage points (95% CI 5.2 to 13.5, p < 0.001), while knowledge of HIV-positive status was not associated with a significant change in consistent condom use (2.5 percentage points, 95% CI -8.0 to 3.1, p = 0.38).

CONCLUSIONS

In urban Uganda, FSWs engaged in safer sex with clients when they perceived that they themselves were not living with HIV. Even in communities with very high HIV prevalence, the majority of the population will test HIV-negative. Our results thus imply that expansion of HIV testing programmes may serve as a behavioural HIV prevention measure among FSWs.

Dual Unsafe Injection and Sexual Behaviors for HIV Infection Among People Who Inject Drugs in Iran

We used two national surveys (2010: N = 1597; 2013: N = 1057) of people who inject drugs (PWID) in past-month to assess the prevalence and population size of PWID with either safe or unsafe injection and sex behaviors, overall and by HIV status. In 2013, only 27.0% (vs. 32.3% in 2010) had safe injection and sex, 24.6% (vs. 23.3% in 2010) had unsafe injection and sex, 26.4% (vs. 26.5% in 2010) had only unsafe injection, and 22.0% (vs. 18.0% in 2010) had unsafe sex only. Among HIV-positive PWID in 2013, only 22.1% (~ 2200 persons) had safe injection and sex, 14.2% (~ 1400 persons) had unsafe injection and sex, 53.1% (~ 5200 persons) had unsafe injection, and 10.6% had unsafe sex (~ 1100 persons). Among HIV-negative PWID in 2013, only 27.5% (~ 22,200 persons) had safe injection and sex, 25.9% (~ 20,900 PWID) had unsafe injection and sex, 23.2% (~ 18,700 persons) had unsafe injection, and 23.3% (~ 18,800 persons) had unsafe sex. HIV-positive and -negative PWID in Iran continue to be at risk of HIV acquisition or transmission which calls for targeted preventions services.

Does Incident Circumcision Lead to Risk Compensation? Evidence From a Population Cohort in KwaZulu-Natal, South Africa

BACKGROUND

Voluntary medical male circumcision reduces men's risk of HIV acquisition and may thus increase HIV risk-related sexual behaviors through risk compensation. We analyze longitudinal data from one of Africa's largest population cohorts using fixed-effects panel estimation to measure the effect of incident circumcision on sexual behaviors.

SETTING

KwaZulu-Natal, South Africa.

METHODS

An open population cohort of men was followed from 2009 to 2015. Men self-reported their circumcision status and sexual behavior annually. We used linear regression models with individual-level fixed effects to measure the effect of incident circumcision on recent sex (past 12 months) and sexual behaviors that increase HIV risk (not using a condom at last sex, never using condoms with the most recent sexual partner, concurrent sexual partners at present, and multiple sexual partners in the past 12 months). We controlled for potential time-varying confounders: calendar year, age, education, and sexual debut.

RESULTS

The 5127 men in the cohort had a median age of 18 years (interquartile range 16-24) at cohort entry. Over the study period, almost 1 in 5 of these men (19.4%) became newly circumcised. Incident circumcision affected neither recent sex [percentage point (PP) change 0.0, 95% confidence interval: -1.2 to 1.3] nor sexual behaviors that increase HIV risk (PP -1.6, 95% confidence interval: -4.5 to 1.4).

CONCLUSIONS

The data from this study strongly reject the hypothesis that circumcision affects sexual risk-taking. Risk compensation should not serve as an argument against increased and accelerated scale-up of circumcision in this and similar communities in South Africa.

The impact of HIV couple testing and counseling on social support among pregnant women and their partners in Lilongwe, Malawi: an observational study

Couples HIV testing and counseling (couple counseling) promotes safer sexual behaviors, increases communication between couples, and decreases HIV transmission. However, the impact of couple counseling on social support, critical for persons living with HIV, has not been examined. Ninety couples with a recently tested HIV-positive pregnant woman (female-positive couples) and 47 couples with a recently tested HIV-negative pregnant woman (female-negative couples) were enrolled in an observational study at an antenatal clinic in Malawi. Each couple member was assessed immediately before and one month after couple counseling for partner, family, and peer social support using the Multidimensional Scale of Perceived Social Support. Before couple counseling, social support was lower among women than men in both female-positive couples (β = -10.00, p < .01) and female-negative couples (β = -8.43, p  < .01). After couple counseling, social support increased for women in female-positive couples (β = 4.01, p < .01) and female-negative couples (β = 4.69, p < .01) but not for men in either type of couple. Couple counseling could be an effective strategy to increase social support for women, including those with recent HIV diagnoses.

The Evidence Project risk of bias tool: assessing study rigor for both randomized and non-randomized intervention studies

BACKGROUND

Different tools exist for assessing risk of bias of intervention studies for systematic reviews. We present a tool for assessing risk of bias across both randomized and non-randomized study designs. The tool was developed by the Evidence Project, which conducts systematic reviews and meta-analyses of behavioral interventions for HIV in low- and middle-income countries.

METHODS

We present the eight items of the tool and describe considerations for each and for the tool as a whole. We then evaluate reliability of the tool by presenting inter-rater reliability for 125 selected studies from seven published reviews, calculating a kappa for each individual item and a weighted kappa for the total count of items.

RESULTS

The tool includes eight items, each of which is rated as being present (yes) or not present (no) and, for some items, not applicable or not reported. The items include (1) cohort, (2) control or comparison group, (3) pre-post intervention data, (4) random assignment of participants to the intervention, (5) random selection of participants for assessment, (6) follow-up rate of 80% or more, (7) comparison groups equivalent on sociodemographics, and (8) comparison groups equivalent at baseline on outcome measures. Together, items (1)-(3) summarize the study design, while the remaining items consider other common elements of study rigor. Inter-rater reliability was moderate to substantial for all items, ranging from 0.41 to 0.80 (median κ = 0.66). Agreement between raters on the total count of items endorsed was also substantial (κw = 0.66).

CONCLUSIONS

Strengths of the tool include its applicability to a range of study designs, from randomized trials to various types of observational and quasi-experimental studies. It is relatively easy to use and interpret and can be applied to a range of review topics without adaptation, facilitating comparability across reviews. Limitations include the lack of potentially relevant items measured in other tools and potential threats to validity of some items. To date, the tool has been applied in over 30 reviews. We believe it is a practical option for assessing risk of bias in systematic reviews of interventions that include a range of study designs.

Adolescents living with HIV in the Copperbelt Province of Zambia: Their reproductive health needs and experiences

Background

Understanding and meeting the reproductive health needs of adolescents living with HIV (ALHIV) is a growing concern since advances in antiretroviral therapy mean that many ALHIV are now living into adulthood and starting to have sex.

Methods

We conducted a mixed-methods study in the Copperbelt Province of Zambia to advance our understanding of the reproductive health needs of ALHIV and to assess the extent to which these needs are being met. We conducted in-depth interviews (IDIs) with 32 ALHIV from two HIV clinics, 23 with their caregivers, and 10 with clinic staff. ALHIV were interviewed twice. We used the data from the qualitative interviews to create a cross-sectional survey that we conducted with 312 ALHIV in three HIV clinics.

Findings

The vast majority of ALHIV reported they wanted to have children in the future but lacked knowledge about preventing mother-to-child transmission. Some sexually active adolescents used condoms, although they wanted more information about and access to non-condom methods. Many ALHIV reported that their first sexual encounters were forced. Religious beliefs prevented some caregivers from discussing premarital sex and contraception with ALHIV. Clinic staff and caregivers had mixed views about integrating contraceptive counseling and method provision into HIV care and treatment services. Few sexually active ALHIV reported that they disclosed their HIV status to their sexual partners and few reported that they knew their sexual partner’s status.

Conclusions

ALHIV are in dire need of comprehensive sexual and reproductive health services and information including a range of contraceptive methods to prevent pregnancy, knowledge about preventing mother-to-child transmission and having a healthy pregnancy, skills related to HIV disclosure and condom negotiation to prevent horizontal transmission, and screening for sexual violence for both males and females if services are available.

Individual, Partner, and Couple Predictors of HIV Infection among Pregnant Women in Malawi: A Case-Control Study

We aimed to understand drivers of HIV-infection in pregnant women in Malawi. The study was conducted in antenatal and labor and delivery wards. HIV-infected women and their partners (cases) were frequency matched in a 1:2 ratio based on age and screening location to HIV-uninfected women and their partners (controls) in a prevalent case-control study. Characteristics associated with female HIV infection were assessed using logistic regression modeling. At screening, HIV-infected women were more likely to have partners outside Lilongwe than HIV-uninfected women (24% vs. 0%, p < 0.0001). Case females were more likely to have HIV-infected study partners than control females (75% vs. 4%, p < 0.0001). The odds of female HIV-infection were higher if either couple member reported ≥ 2 lifetime marriages (OR 9.0, CI 2.6-30.9) or ≥ 3 lifetime partners (OR 18.0, CI 3.1-103.6) and lower if either reported past couple HIV testing and counseling (OR 0.1, CI 0.04-0.3). Targeting women with migrating partners, promoting couple HIV testing and counseling, and limiting partners could slow HIV transmission.

"We have heard it together": a qualitative analysis of couple HIV testing and counselling recruitment in Malawi's Option B+ programme

Encouraging HIV-infected pregnant women to recruit male partners for couple HIV testing and counselling (CHTC) is promoted by the World Health Organization, but remains challenging. Formal strategies for recruiting the male partners of pregnant women have not been explored within an Option B+ programme. Our objective was to learn about experiences surrounding CHTC recruitment within a formal CHTC recruitment study. A randomised controlled trial comparing two CHTC recruitment strategies was conducted among HIV-infected pregnant women presenting to Bwaila Antenatal Unit in 2014. Women were randomised to receive an invitation to attend the clinic as a couple or this invitation plus clinic-led phone and community tracing. A qualitative study was conducted with a subset of participants to learn about recruitment. This paper describes experiences of a subset of HIV-infected pregnant women (N = 20) and male partners (N = 17). One on one in-depth interviews were audio-recorded, transcribed, translated, and coded using content analysis. Nearly all women presented the invitation and disclosed their HIV-positive status to their partners on the day of HIV diagnosis, often to facilitate pill-taking. Men and women in both arms perceived the messages to be more compelling since they came from the clinic, rather than the woman herself. Couples who attended CHTC displayed greater care for one another and mutual support for HIV-related behaviours. Facilitating CHTC with invitations and tracing can support CHTC uptake and support for HIV-affected couples. In an Option B+ context, inviting partners for CHTC can facilitate male involvement and have important benefits for families.

'I don't even know how to start that kind of conversation': HIV communication between mothers and adolescents with perinatally acquired HIV

Young people with perinatally acquired HIV are now surviving into late adolescence and adulthood. We explored HIV communication within mother/adolescent dyads following naming of the adolescents' HIV. Five adolescents with perinatally acquired HIV (14-16 years) and their biological mothers were interviewed separately. HIV communication between mothers and children was rare. Discussion most commonly related to biomedical aspects of HIV. Onward HIV disclosure was discouraged by mothers, which often contrasted with adolescents' beliefs. Discussing emotional and sexual aspects of HIV was mutually avoided. Culturally sensitive support and guidance should be offered to families about discussing HIV, considering potentially differing perspectives.

Direct provision versus facility collection of HIV self-tests among female sex workers in Uganda: A cluster-randomized controlled health systems trial

BACKGROUND

HIV self-testing allows HIV testing at any place and time and without health workers. HIV self-testing may thus be particularly useful for female sex workers (FSWs), who should test frequently but face stigma and financial and time barriers when accessing healthcare facilities.

METHODS AND FINDINGS

We conducted a cluster-randomized controlled health systems trial among FSWs in Kampala, Uganda, to measure the effect of 2 HIV self-testing delivery models on HIV testing and linkage to care outcomes. FSW peer educator groups (1 peer educator and 8 participants) were randomized to either (1) direct provision of HIV self-tests, (2) provision of coupons for free collection of HIV self-tests in a healthcare facility, or (3) standard of care HIV testing. We randomized 960 participants in 120 peer educator groups from October 18, 2016, to November 16, 2016. Participants' median age was 28 years (IQR 24-32). Our prespecified primary outcomes were self-report of any HIV testing at 1 month and at 4 months; our prespecified secondary outcomes were self-report of HIV self-test use, seeking HIV-related medical care and ART initiation. In addition, we analyzed 2 secondary outcomes that were not prespecified: self-report of repeat HIV testing-to understand the intervention effects on frequent testing-and self-reported facility-based testing-to quantify substitution effects. Participants in the direct provision arm were significantly more likely to have tested for HIV than those in the standard of care arm, both at 1 month (risk ratio [RR] 1.33, 95% CI 1.17-1.51, p < 0.001) and at 4 months (RR 1.14, 95% CI 1.07-1.22, p < 0.001). Participants in the direct provision arm were also significantly more likely to have tested for HIV than those in the facility collection arm, both at 1 month (RR 1.18, 95% CI 1.07-1.31, p = 0.001) and at 4 months (RR 1.03, 95% CI 1.01-1.05, p = 0.02). At 1 month, fewer participants in the intervention arms had sought medical care for HIV than in the standard of care arm, but these differences were not significant and were reduced in magnitude at 4 months. There were no statistically significant differences in ART initiation across study arms. At 4 months, participants in the direct provision arm were significantly more likely to have tested twice for HIV than those in the standard of care arm (RR 1.51, 95% CI 1.29-1.77, p < 0.001) and those in the facility collection arm (RR 1.22, 95% CI 1.08-1.37, p = 0.001). Participants in the HIV self-testing arms almost completely replaced facility-based testing with self-testing. Two adverse events related to HIV self-testing were reported: interpersonal violence and mental distress. Study limitations included self-reported outcomes and limited generalizability beyond FSWs in similar settings.

CONCLUSIONS

In this study, HIV self-testing appeared to be safe and increased recent and repeat HIV testing among FSWs. We found that direct provision of HIV self-tests was significantly more effective in increasing HIV testing among FSWs than passively offering HIV self-tests for collection in healthcare facilities. HIV self-testing could play an important role in supporting HIV interventions that require frequent HIV testing, such as HIV treatment as prevention, behavior change for transmission reduction, and pre-exposure prophylaxis.

The WHO public health approach to HIV treatment and care: looking back and looking ahead

In 2006, WHO set forth its vision for a public health approach to delivering antiretroviral therapy. This approach has been broadly adopted in resource-poor settings and has provided the foundation for scaling up treatment to over 19·5 million people. There is a global commitment to end the AIDS epidemic as a public health threat by 2030 and, to support this goal, there are opportunities to adapt the public health approach to meet the ensuing challenges. These challenges include the need to improve identification of people with HIV infection through expanded approaches to testing; further simplify and improve treatment and laboratory monitoring; adapt the public health approach to concentrated epidemics; and link HIV testing, treatment, and care to HIV prevention. Implementation of these key public health principles will bring countries closer to the goals of controlling the HIV epidemic and providing universal health coverage.

Epidemiological HIV infection surveillance among subjects with risk behaviours in the city of Messina (Sicily) from 1992 to 2015

INTRODUCTION

Epidemiological studies are a key element in determining the evolution and spread of HIV infection among the world population. Knowledge of the epidemiological dynamics improves strategies for prevention and monitoring.

METHODS

We examined 2,272 subjects who voluntarily underwent HIV testing from January 1992 to December 2015. For each subject, an anonymous form was completed to obtain information on personal data, sexual habits and exposure to risk factors.

RESULTS

The number of subjects undergoing the screening test has increased over the years and the average age of the tested subjects has decreased over time. The main motivation for undergoing HIV testing is unprotected sex. Although heterosexual subjects taking the test were more numerous than homosexuals in this study, an increase in the latter over time should be highlighted.

CONCLUSIONS

Although the number of tests performed has increased over the years, the persistence of unprotected sex shows an inadequate perception of risk. Therefore, it is necessary to implement programmes to increase the general awareness of HIV infection. It is also essential to undertake constant monitoring of behaviour, risk perception and the application of the screening test via surveillance systems in order to implement effective and efficient prevention.

Non-specialist psychosocial support interventions for women living with HIV: A systematic review

Many women living with HIV experience a range of physical, social, and psychological challenges linked to their HIV status. Psychosocial support interventions may help women cope with these challenges and may allow women to make better decisions around their sexual and reproductive health (SRH), yet no reviews have summarized the evidence for the impact of such interventions on well-being and SRH decision-making among women living with HIV. We systematically reviewed the evidence for non-specialist delivered psychosocial support interventions for women living with HIV, which are particularly relevant in low-resource settings. Outcomes of interest included mental, emotional, social well-being and/or quality of life, common mental health disorders, and SRH decision-making. Searching was conducted through four electronic databases and secondary reference screening. Systematic methods were used for screening and data abstraction. Nine articles met the inclusion criteria, showing positive or mixed results for well-being and depressive symptoms indicators. No studies reported on SRH decision-making outcomes. The available evidence suggests that psychosocial support interventions may improve self-esteem, coping and social support, and reduce depression, stress, and perceived stigma. However, evidence is mixed. Most studies placed greater emphasis on instrumental health outcomes to prevent HIV transmission than on the intrinsic well-being and SRH of women living with HIV. Many interventions included women living with HIV in their design and implementation. More research is required to understand the most effective interventions, and their effect on sexual and reproductive health and rights.

Prevalence of fertility desire and its associated factors among 15- to 49-year-old people living with HIV/AIDS in Addis Ababa, Ethiopia: a cross-sectional study design

Background

The magnitude of unprotected sex to satisfy the desire for fertility among people living with HIV/AIDS (PLHIV) may rise more due to the availability of antiretroviral therapy (ART) in most HIV-affected countries. This could, however, have the risk of passing on HIV to sexual partners and children. The aim of this study, therefore, was to determine the magnitude and factors associated with the fertility desire of reproductive-age PLHIV in Addis Ababa, Ethiopia, for research-based and timely actions.

Methods

A cross-sectional study was carried out from April to June 2016 among 442 randomly selected, reproductive-age PLHIV who had been attending ART clinics in Addis Ababa. Twelve experienced and trained nurses collected the data. The questionnaire was pretested and interviewer-administered, and the interview was executed after obtaining voluntary consent from each study subject. The data were then cleaned and analyzed by using Epi Info version 3.5.4 and SPSS version 20.0, respectively. Binary logistic regression was done in order to describe the association of fertility desire with some sociodemographic and sexual behavior-related factors.

Results

Among the total 441 respondents, 54.6% reported the desire for fertility, 87% disclosed their HIV status, 24.3% had two or more sexual partners in the earlier year, and only 55.6% used a condom during their last sexual intercourse. In addition, current health status (AOR=2.03; 95% CI: 1.01–4.07) and partner being tested for HIV (AOR=6.31; 95% CI: 1.35–29.64) showed statistically significant associations with fertility desire during multivariate logistic regression analysis.

Conclusion

A considerable number of PLHIV in the study area reported a desire for having children. Current health status and partner being tested for HIV were found to be factors associated with the fertility desire among PLHIV. Thus, more efforts to effectively address the health concerns related to fertility desire and risky sexual behavior among HIV-infected people of reproductive age could play a significant role in prevention and control measures against HIV/AIDS epidemic.

The Relationship of Repeated Technical Assistance Support Visits to the Delivery of Positive Health, Dignity, and Prevention (PHDP) Messages by Healthcare Providers in Mozambique: A Longitudinal Multilevel Analysis

BACKGROUND

Positive health, dignity, and prevention (PHDP) is Mozambique's strategy to engage clinicians in the delivery of prevention messages to their HIV-positive clients. This national implementation strategy uses provider trainings on offering key messages and focuses on intervening on 9 evidence-based risk reduction areas. We investigated the impact of longitudinal technical assistance (TA) as an addition to this basic training.

METHODS

We followed 153 healthcare providers in 5 Mozambican provinces over 6 months to evaluate the impact of on-site, observation-based TA on PHDP implementation. Longitudinal multilevel models were estimated to model change in PHDP message delivery over time among individual providers.

RESULTS

With each additional TA visit, providers delivered about 1 additional PHDP message ( P < .001); clinicians and nonclinicians started at about the same baseline level, but clinicians improved more quickly ( P = .004). Message delivery varied by practice sector; maternal and child health sectors outperformed other sectors.

CONCLUSION

Longitudinal TA helped reach the programmatic goals of the PHDP program in Mozambique.

Cultural Adaptation of an Evidence-Informed Psychosocial Intervention to Address the Needs of PHIV+ Youth in Thailand

Globally, pediatric HIV has largely become an adolescent epidemic. Thailand has the highest HIV prevalence in Asia (1.2%), with more than 14,000 children living with HIV. There is growing demand for evidence-based psychosocial interventions for this population that include health and mental health support and sexual risk reduction, which can be integrated into HIV care systems. To address this need, a multidisciplinary team of Thai and US researchers adapted an existing evidence-informed, family-based intervention, The Collaborative HIV Prevention and Adolescent Mental Health Program + (CHAMP+), which has been tested in multiple global trials. Using community-based participatory research methods, changes to the intervention curriculum were made to address language, culture, and Thai family life. Involvement of families, youth, and stakeholders in the adaptation process allowed for identification of salient issues and of program delivery methods that would increase engagement. Participants endorsed using a cartoon-based curriculum format for fostering discussion (as in CHAMP+ South Africa) given stigma around discussing HIV in the Thai context. The Thai version of CHAMP+ retained much of the curriculum content incorporating culturally appropriate metaphors and story line. Sessions focus on family communication, coping, disclosure, stigma, social support, and HIV education. This paper explores lessons learned through the adaption process of CHAMP+ Thailand that are applicable to other interventions and settings. It discusses how culturally informed adaptations can be made to interventions while maintaining core program components.

Interventions to strengthen the HIV prevention cascade: a systematic review of reviews

BACKGROUND

Much progress has been made in interventions to prevent HIV infection. However, development of evidence-informed prevention programmes that translate the efficacy of these strategies into population effect remain a challenge. In this systematic review, we map current evidence for HIV prevention against a new classification system, the HIV prevention cascade.

METHODS

We searched for systematic reviews on the effectiveness of HIV prevention interventions published in English from Jan 1, 1995, to July, 2015. From eligible reviews, we identified primary studies that assessed at least one of: HIV incidence, HIV prevalence, condom use, and uptake of HIV testing. We categorised interventions as those seeking to increase demand for HIV prevention, improve supply of HIV prevention methods, support adherence to prevention behaviours, or directly prevent HIV. For each specific intervention, we assigned a rating based on the number of randomised trials and the strength of evidence.

FINDINGS

From 88 eligible reviews, we identified 1964 primary studies, of which 292 were eligible for inclusion. Primary studies of direct prevention mechanisms showed strong evidence for the efficacy of pre-exposure prophylaxis (PrEP) and voluntary medical male circumcision. Evidence suggests that interventions to increase supply of prevention methods such as condoms or clean needles can be effective. Evidence arising from demand-side interventions and interventions to promote use of or adherence to prevention tools was less clear, with some strategies likely to be effective and others showing no effect. The quality of the evidence varied across categories.

INTERPRETATION

There is growing evidence to support a number of efficacious HIV prevention behaviours, products, and procedures. Translating this evidence into population impact will require interventions that strengthen demand for HIV prevention, supply of HIV prevention technologies, and use of and adherence to HIV prevention methods.

Sex in the shadow of HIV: A systematic review of prevalence, risk factors, and interventions to reduce sexual risk-taking among HIV-positive adolescents and youth in sub-Saharan Africa

BACKGROUND

Evidence on sexual risk-taking among HIV-positive adolescents and youth in sub-Saharan Africa is urgently needed. This systematic review synthesizes the extant research on prevalence, factors associated with, and interventions to reduce sexual risk-taking among HIV-positive adolescents and youth in sub-Saharan Africa.

METHODS

Studies were located through electronic databases, grey literature, reference harvesting, and contact with researchers. Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were followed. Quantitative studies that reported on HIV-positive participants (10-24 year olds), included data on at least one of eight outcomes (early sexual debut, inconsistent condom use, older partner, transactional sex, multiple sexual partners, sex while intoxicated, sexually transmitted infections, and pregnancy), and were conducted in sub-Saharan Africa were included. Two authors piloted all processes, screened studies, extracted data independently, and resolved any discrepancies. Due to variance in reported rates and factors associated with sexual risk-taking, meta-analyses were not conducted.

RESULTS

610 potentially relevant titles/abstracts resulted in the full text review of 251 records. Forty-two records (n = 35 studies) reported one or multiple sexual practices for 13,536 HIV-positive adolescents/youth from 13 sub-Saharan African countries. Seventeen cross-sectional studies reported on individual, relationship, family, structural, and HIV-related factors associated with sexual risk-taking. However, the majority of the findings were inconsistent across studies, and most studies scored <50% in the quality checklist. Living with a partner, living alone, gender-based violence, food insecurity, and employment were correlated with increased sexual risk-taking, while knowledge of own HIV-positive status and accessing HIV support groups were associated with reduced sexual risk-taking. Of the four intervention studies (three RCTs), three evaluated group-based interventions, and one evaluated an individual-focused combination intervention. Three of the interventions were effective at reducing sexual risk-taking, with one reporting no difference between the intervention and control groups.

CONCLUSION

Sexual risk-taking among HIV-positive adolescents and youth is high, with inconclusive evidence on potential determinants. Few known studies test secondary HIV-prevention interventions for HIV-positive youth. Effective and feasible low-cost interventions to reduce risk are urgently needed for this group.

Design and implementation of a factorial randomized controlled trial of methadone maintenance therapy and an evidence-based behavioral intervention for incarcerated people living with HIV and opioid dependence in Malaysia

Incarcerated people living with HIV and opioid dependence face enormous challenges to accessing evidence-based treatment during incarceration and after release into the community, placing them at risk of poor HIV treatment outcomes, relapse to opioid use and accompanying HIV transmission risk behaviors. Here we describe in detail the design and implementation of Project Harapan, a prospective clinical trial conducted among people living with HIV and opioid dependence who transitioned from prison to the community in Malaysia from 2010 to 2014. This trial involved 2 interventions: within-prison initiation of methadone maintenance therapy and an evidence-based behavioral intervention adapted to the Malaysian context (the Holistic Health Recovery Program for Malaysia, HHRP-M). Individuals were recruited and received the interventions while incarcerated and were followed for 12months after release to assess post-release HIV transmission risk behaviors and a range of other health-related outcomes. Project Harapan was designed as a fully randomized 2×2 factorial trial where individuals would be allocated in equal proportions to methadone maintenance therapy and HHRP-M, methadone maintenance therapy alone, HHRP-M alone, or control. Partway through study implementation, allocation to methadone maintenance therapy was changed from randomization to participant choice; randomization to HHRP-M continued throughout. We describe the justification for this study; the development and implementation of these interventions; changes to the protocol; and screening, enrollment, treatment receipt, and retention of study participants. Logistical, ethical, and analytic issues associated with the implementation of this study are discussed.

Emtonjeni-A Structural Intervention to Integrate Sexual and Reproductive Health into Public Sector HIV Care in Cape Town, South Africa: Results of a Phase II Study

Integration of sexual and reproductive health within HIV care services is a promising strategy for increasing access to family planning and STI services and reducing unwanted pregnancies, perinatal HIV transmission and maternal and infant mortality among people living with HIV and their partners. We conducted a Phase II randomized futility trial of a multi-level intervention to increase adherence to safer sex guidelines among those wishing to avoid pregnancy and adherence to safer conception guidelines among those seeking conception in newly-diagnosed HIV-positive persons in four public-sector HIV clinics in Cape Town. Clinics were pair-matched and the two clinics within each pair were randomized to either a three-session provider-delivered enhanced intervention (EI) (onsite contraceptive services and brief milieu intervention for staff) or standard-of-care (SOC) provider-delivered intervention. The futility analysis showed that we cannot rule out the possibility that the EI intervention has a 10 % point or greater success rate in improving adherence to safer sex/safer conception guidelines than does SOC (p = 0.573), indicating that the intervention holds merit, and a larger-scale confirmatory study showing whether the EI is superior to SOC has merit.

Can Policy Interventions Affect HIV-Related Behaviors? A Systematic Review of the Evidence from Low- and Middle-Income Countries

In their response to HIV, many countries have adopted and enacted policies to reduce transmission and increase HIV-related service use. Theoretically, policy-level interventions for HIV prevention have the potential to improve health behavior outcomes. These policy interventions vary in their scale, from relatively minor changes in clinical policy to major national legal initiatives. Assessing the effectiveness of HIV policy interventions is a challenging undertaking. While many policies exist and guide HIV programmes, relatively few have specifically been evaluated for their effects on reducing HIV risk taking or increasing HIV health-seeking behaviors. Thus, questions on the effectiveness of policy interventions to prevent HIV and change HIV-related risk behaviors remain largely unanswered. To address this current gap in the literature, we systematically reviewed the existing evidence on the effect of HIV policy interventions on changing HIV-related behaviors in low-and middle-income countries.

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.

Increasing Uptake of HIV, Sexually Transmitted Infection, and Family Planning Services, and Reducing HIV-Related Risk Behaviors Among Youth Living With HIV in Uganda

PURPOSE

To address barriers to care for youth living with HIV (YLHIV), the Link Up project implemented a peer-led intervention model that provided a comprehensive package of HIV and sexual and reproductive health and rights services through community-based peer support groups for YLHIV. Peer educators delivered targeted counseling and health education, and referred YLHIV to antiretroviral therapy (ART), and reproductive health services that were available at youth-oriented sexual and reproductive health and rights facilities.

METHODS

At baseline (October to November 2014), 37 peer support groups for YLHIV were established in Luwero and Nakasongola districts. During this same time period, we recruited a cohort of 473 support group members, aged 15-24 years. After a 9-month intervention period (January to September 2015), we completed the end-line survey with 350 members of the original cohort. Multivariate logistic regression analysis applied to longitudinal data was used to assess changes in key outcomes from baseline to end line.

RESULTS

Multivariate analyses showed significant increases at end line, compared with baseline, in self-efficacy (adjusted odds ratio [AOR]: 1.8 [1.3-2.6]), comprehensive HIV knowledge [AOR: 1.8 [1.3-2.6]), HIV disclosure (AOR: 1.6 [1.01-2.6]), condom use at last sex (AOR: 1.7 [1.2-2.5]), sexually transmitted infection uptake (AOR: 2.1 [1.5-2.9]), ART uptake (AOR: 2.5 [1.6-4.0]), ART adherence (AOR: 2.5 [1.3-4.9]), CD4 testing (AOR: 2.4 [1.5-3.6]), and current use of a modern contraceptive method (AOR: 1.7 [1.1-2.7]).

CONCLUSIONS

Link Up's intervention strategy likely contributed to observed increases in self-efficacy, knowledge of HIV, condom use, HIV disclosure ART utilization and adherence, CD4 testing, STI testing uptake, and use of modern family planning methods. This model shows promise and should be adapted for use among YLHIV in similar settings and evaluated further.

Frequency and predictors of estimated HIV transmissions and bacterial STI acquisition among HIV-positive patients in HIV care across three continents

Introduction

Successful global treatment as prevention (TasP) requires identifying HIV-positive individuals at high risk for transmitting HIV, and having impact via potential infections averted. This study estimated the frequency and predictors of numbers of HIV transmissions and bacterial sexually transmitted infection (STI) acquisition among sexually active HIV-positive individuals in care from three representative global settings.

Methods

HIV-positive individuals (n=749), including heterosexual men, heterosexual women and men who have sex with men (MSM) in HIV care, were recruited from Chiang Mai (Thailand), Rio De Janeiro (Brazil) and Lusaka (Zambia). Participants were assessed on HIV and STI sexual transmission risk variables, psychosocial characteristics and bacterial STIs at enrolment and quarterly for 12 months (covering 15 months). Estimated numbers of HIV transmissions per person were calculated using reported numbers of partners and sex acts together with estimates of HIV transmissibility, accounting for ART treatment and condom use.

Results

An estimated 3.81 (standard error, (SE)=0.63) HIV transmissions occurred for every 100 participants over the 15 months, which decreased over time. The highest rate was 19.50 (SE=1.68) for every 100 MSM in Brazil. In a multivariable model, country×risk group interactions emerged: in Brazil, MSM had 2.85 (95% CI=1.45, 4.25, p<0.0001) more estimated transmissions than heterosexual men and 3.37 (95% CI=2.01, 4.74, p<0.0001) more than heterosexual women over the 15 months. For MSM and heterosexual women, the combined 12-month STI incidence rate for the sample was 22.4% (95% CI=18.1%, 27.3%; incidence deemed negligible in heterosexual men). In the multivariable model, MSM had 12.3 times greater odds (95% CI=4.44, 33.98) of acquiring an STI than women, but this was not significant in Brazil. Higher alcohol use on the Alcohol Use Disorders Identification Test (OR=1.04, 95% CI=1.01, 1.08) was also significantly associated with increased STI incidence. In bivariate models for both HIV transmissions and STI incidence, higher depressive symptoms were significant predictors.

Conclusions

These data help to estimate the potential number of HIV infections transmitted and bacterial STIs acquired over time in patients established in care, a group typically considered at lower transmission risk, and found substantial numbers of estimated HIV transmissions. These findings provide an approach for evaluating the impact (in phase 2 studies) and potentially cost-effectiveness of global TasP efforts.

Delivering Prevention Interventions to People Living with HIV in Clinical Care Settings: Results of a Cluster Randomized Trial in Kenya, Namibia, and Tanzania

We conducted a group randomized trial to assess the feasibility and effectiveness of a multi-component, clinic-based HIV prevention intervention for HIV-positive patients attending clinical care in Namibia, Kenya, and Tanzania. Eighteen HIV care and treatment clinics (six per country) were randomly assigned to intervention or control arms. Approximately 200 sexually active clients from each clinic were enrolled and interviewed at baseline and 6- and 12-months post-intervention. Mixed model logistic regression with random effects for clinic and participant was used to assess the effectiveness of the intervention. Of 3522 HIV-positive patients enrolled, 3034 (86 %) completed a 12-month follow-up interview. Intervention participants were significantly more likely to report receiving provider-delivered messages on disclosure, partner testing, family planning, alcohol reduction, and consistent condom use compared to participants in comparison clinics. Participants in intervention clinics were less likely to report unprotected sex in the past 2 weeks (OR = 0.56, 95 % CI 0.32, 0.99) compared to participants in comparison clinics. In Tanzania, a higher percentage of participants in intervention clinics (17 %) reported using a highly effective method of contraception compared to participants in comparison clinics (10 %, OR = 2.25, 95 % CI 1.24, 4.10). This effect was not observed in Kenya or Namibia. HIV prevention services are feasible to implement as part of routine care and are associated with a self-reported decrease in unprotected sex. Further operational research is needed to identify strategies to address common operational challenges including staff turnover and large patient volumes.

How do HIV-negative individuals in sub-Saharan Africa change their sexual risk behaviour upon learning their serostatus? A systematic review

OBJECTIVE

To determine whether, and how, sexual behaviour of HIV-negative individuals in sub-Saharan Africa (SSA) changes upon learning their serostatus.

METHODS

We systematically reviewed the published literature using EMBASE and Medline to search for publications between 2004 and 2014. We included studies that quantified behaviour change (condom use, number of sexual partners or sex acts) following an HIV test in HIV-negative adults in SSA, and extracted relevant data including study characteristics and measurement type.

RESULTS

From 2185 unique citations, n=14 studies representing 22 390 participants met our inclusion criteria. We did not pool data due to marked heterogeneity in study outcome measures. The proportion of participants reporting consistent condom use (n=6) post-testing ranged from 7.6% greater, to 10.6% fewer, while 'no condom use' (n=5) ranged from 40.0% less, to 0.7% more. Condom use in serodiscordant couples increased (n=3). Five studies measured the proportion reporting abstinence, finding an increase of 10.9% to a decrease of 5.3% post-testing. The post-testing change in the mean number of sex acts (n=3) ranged from a relative decrease of 15.7% to a relative increase of 9.4%. Two studies reported relative decreases in the mean number of sexual partners of 35.2% and 14.0%. Three studies examining serodiscordant primary relationships specifically all showed increases in extrarelational sex.

CONCLUSIONS

With the exception of serodiscordant couples, there is variable evidence that awareness of one's serostatus leads to substantial changes in risk behaviour among HIV-negative individuals. Further research is needed to estimate the behavioural impact of learning one's serostatus in SSA.

The effect of HIV counselling and testing on HIV acquisition in sub-Saharan Africa: a systematic review

OBJECTIVES

Annually, millions of people in sub-Saharan Africa (SSA) receive HIV counselling and testing (HCT), a service designed to inform persons of their HIV status and, if HIV uninfected, reduce HIV acquisition risk. However, the impact of HCT on HIV acquisition has not been systematically evaluated. We conducted a systematic review to assess this relationship in SSA.

METHODS

We searched for articles from SSA meeting the following criteria: an HIV-uninfected population, HCT as an exposure, longitudinal design and an HIV acquisition endpoint. Three sets of comparisons were assessed and divided into strata: sites receiving HCT versus sites not receiving HCT (Strata A), persons receiving HCT versus persons not receiving HCT (Strata B) and persons receiving couple HCT (cHCT) versus persons receiving individual HCT (Strata C).

RESULTS

We reviewed 1635 abstracts; eight met all inclusion criteria. Strata A consisted of one cluster randomised trial with a non-significant trend towards HCT being harmful: incidence rate ratio (IRR): 1.4. Strata B consisted of five observational studies with non-significant unadjusted IRRs from 0.6 to 1.3. Strata C consisted of two studies. Both displayed trends towards cHCT being more protective than individual HCT (IRRs: 0.3-0.5). All studies had at least one design limitation.

CONCLUSIONS

In spite of intensive scale-up of HCT in SSA, few well-designed studies have assessed the prevention impacts of HCT. The limited body of evidence suggests that individual HCT does not have a consistent impact on HIV acquisition, and cHCT is more protective than individual HCT.

HIV Status Disclosure through Family-Based Intervention Supports Parenting and Child Mental Health in Rwanda

INTRODUCTION

Few evidence-based interventions exist to support parenting and child mental health during the process of caregiver HIV status disclosure in sub-Saharan Africa. A secondary analysis of a randomized-controlled trial was conducted to examine the role of family-based intervention versus usual social work care (care as usual) in supporting HIV status disclosure within families in Rwanda.

METHOD

Approximately 40 households were randomized to family-based intervention and 40 households to care as usual. Parenting, family unity, and child mental health during the process of disclosure were studied using quantitative and qualitative research methods.

RESULTS

Many of the families had at least one caregiver who had not disclosed their HIV status at baseline. Immediately post-intervention, children reported lower parenting and family unity scores compared with those in the usual-care group. These changes resolved at 3-month follow-up. Qualitative reports from clinical counselor intervention sessions described supported parenting during disclosure. Overall findings suggest adjustments in parenting, family unity, and trust surrounding the disclosure process.

CONCLUSION

Family-based intervention may support parenting and promote child mental health during adjustment to caregiver HIV status disclosure. Further investigation is required to examine the role of family-based intervention in supporting parenting and promoting child mental health in HIV status disclosure.
