New heterosexually transmitted HIV infections in married or cohabiting couples in urban Zambia and Rwanda: an analysis of survey and clinical data

HIV pre-exposure prophylaxis uptake and associated factors among HIV serodiscordant heterosexual couples in Nairobi City County, Kenya

HIV antiretroviral drugs used as pre-exposure prophylaxis (PrEP) are effective for HIV prevention. This study evaluated determinants of PrEP uptake among HIV-negative spouses in HIV-serodiscordant heterosexual relationships in Nairobi City County, Kenya. Of the 424 participants, 114 reported current PrEP use, resulting in a PrEP uptake of 27% (23-31%). The top reason for current PrEP use was to achieve pregnancy (n = 69; 61%). Of the 424 participants, 209 (49%) had never used PrEP, and the leading reasons for never using PrEP were lack of PrEP information (38%) and self-perceived low risk for HIV (36%). Factors associated with decreased likelihood of PrEP use included: low level of education (p = 0.026), self-perception of being at low-to-no risk for HIV (p = 0.021), lack of desire for more children (p = 0.005) and lack of knowledge that PrEP is offered free (p = 0.004). Female sex (aOR = 2.3; 95% CI: 1.4-4.0) and lack of condom use (aOR = 2.5; 95% CI: 1.4-4.5) were associated with increased odds of taking PrEP. Uptake of PrEP among HIV-serodiscordant couples in Nairobi City County was low, and PrEP use was driven by desire to fulfill pregnancy intentions. Aggressive educational campaigns to address self-HIV-risk perceptions and increase PrEP knowledge are necessary for increased PrEP demand.

'They went for the test together but came back separately': a constructivist grounded theory perspective on male engagement in antenatal HIV testing in Bamenda, Cameroon

INTRODUCTION

Male engagement in HIV testing during pregnancy significantly contributes towards the prevention of maternal seroconversion and paediatric HIV acquisition. Despite this, men especially the male partners of pregnant women have been consistently missing in the HIV prevention cascade. The factors accounting for sub-optimal levels in male engagement intersect but reasons for this are poorly understood. Using the combined perspectives of pregnant women and their partners, this study aims to expand the evidence on the forces that influence prenatal HIV testing behaviours among couples in Bamenda, Cameroon.

METHODS

This qualitative study purposively selected pregnant women receiving prenatal care for semi-structured interviews (n = 38); focus group discussion (n = 6) and their male partners (n = 30 for semi-structured interviews and n = 6 for focus group discussion) in Nkwen Baptist Hospital-an urban hospital in Bamenda, Cameroon. Nvivo was used for data management and subsequently we performed a grounded theory analysis through memoing and constant comparisons.

RESULTS

Maternal HIV risk perception was the prominent theme intersecting with couple communication, perceptions on HIV testing outcome, and engagement of male partners by facility staff to influence couple prenatal HIV testing behaviours. Although participants recognised the need for couple HIV testing, individual, interspousal, structural and socio-cultural factors determined uptake of male partner testing. Perceptions on HIV risk were largely inaccurate and strongly gendered. For example, normative expectations on female fidelity were perceived as a buffer against HIV acquisition but this was not the norm regarding male partner behaviour. Also, couple communication was rare or subtle-mostly initiated by women who suspected spousal infidelity. For some men, HIV testing was a conscious decision to confirm fidelity, for others this was challenged by the fear of sero-discordant results and assumptions that maternal test results were a representation of their sero-status.

CONCLUSION

Male partner involvement in prenatal HIV testing is largely influenced by gendered perceptions on HIV risk and couple testing outcomes. Given that these perceptions are moderated by spousal communication and the engagement of male partners by health facility staff, we call for gender-transformative interventions and policies that offer education on prenatal HIV risk, support couple communication and spousal disclosure.

"We chose PrEP because I wanted to be sure that this child my wife was going to conceive was indeed mine." Factors influencing the choice of safer conception methods and experiences with its use: a qualitative study among HIV sero-discordant couples in Zimbabwe

BACKGROUND

Safer conception services are needed to minimize HIV transmission among HIV sero-discordant couples desiring pregnancy. Few studies have evaluated the choices couples make when they are offered multiple safer conception methods or real-world method acceptability. This paper addresses an important knowledge gap regarding factors that influence the choice of safer conception methods, couples' actual experiences using safer conception methods, and why some couples switch safer conception methods.

METHODS

Between February and June 2019, we conducted semi-structured in-depth interviews among 14 men and 17 women, representing 17 couples who exited the SAFER study-a pilot safer conception study for HIV sero-discordant couples in Zimbabwe that offered couples a choice of ART with monthly viral load monitoring (ART/VL), oral PrEP, vaginal insemination, and semen washing. All couples in SAFER had used at least two safer conception methods.

RESULTS

We found that safer conception method choice often centered around a desire for intimacy, condomless sex, and certainty in the conception process, particularly for men. Method-related attributes such as familiarity, perceived ease of use, side effects, and perceived level of effectiveness in preventing HIV and achieving pregnancy influenced method choice, switching, and satisfaction. Concerns were expressed about each safer conception method and couples were willing to try different methods until they found method(s) that worked for them. The majority of participants reported having positive experiences using safer conception, especially those using ART/VL + PrEP, citing that they were able to attempt pregnancy for the first time with peace of mind and experienced joy and satisfaction from being able to achieve pregnancy safely.

CONCLUSIONS

The differences in method preferences and experiences voiced by participants in this study and in other studies from the region point to the importance of having a variety of safer conception options in the service delivery package and addressing concerns about paternity, intimacy, and method-related attributes to enable HIV sero-discordant couples to safely achieve their reproductive goals.

Clinical Implications of HIV Treatment and Prevention for Polygamous Families in Kenya and Uganda: "My Co-Wife Is the One Who Used to Encourage Me"

Polygamy is the practice of marriage to multiple partners. Approximately 6-11% of households in Uganda and 4-11% of households in Kenya are polygamous. The complex families produced by polygamous marriage customs give rise to additional considerations for healthcare providers and public health messaging around HIV care. Using 27 in-depth, semi-structured qualitative interviews with participants in two studies in rural Kenya and Uganda, we analysed challenges and opportunities that polygamous families presented in the diagnosis, treatment and prevention of HIV, and provider roles in improving HIV outcomes in these families. Overall, prevention methods seemed more justifiable to families where co-wives live far apart than when all members live in the same household. In treatment, diagnosis of one member did not always lead to disclosure to other members, creating an adverse home environment; but sometimes diagnosis of one wife led not only to diagnosis of the other, but also to greater household support.

Spatial variation of premarital HIV testing and its associated factors among married women in Ethiopia: Multilevel and spatial analysis using 2016 demographic and health survey data

BACKGROUND

Africa is the most severely affected area, accounting for more than two-thirds of the people living with HIV. In sub-Saharan Africa, more than 85% of new HIV-infected adolescents and 63% of all new HIV infections are accounted for by women. Ethiopia has achieved a 50% incidence rate reduction. However, mortality rate reduction is slow, as the estimated prevalence in 2021 is 0.8%. In sub-Saharan Africa, heterosexual transmission accounts for the majority of HIV infections, and women account for 58% of people living with HIV. Most of these transmissions took place during marriage. Thus, this study aimed to explore the spatial variation of premarital HIV testing across regions of Ethiopia and identify associated factors.

METHODS

A cross-sectional study design was employed. A total of 10223 weighted samples were taken from individual datasets of the 2016 Ethiopian Demographic and Health Survey. STATA version 14 and ArcGIS version 10.8 software's were used for analysis. A multilevel mixed-effect generalized linear model was fitted, and an adjusted prevalence Ratio with a 95% CI and p-value < 0.05 was used to declare significantly associated factors. Multilevel models were compared using information criteria and log-likelihood. Descriptive and spatial regression analyses (geographical weighted regression and ordinary least squares analysis) were conducted. Models were compared using AICc and adjusted R-squared. The local coefficients of spatial explanatory variables were mapped.

RESULTS

In spatial regression analysis, secondary and above education level, richer and above wealth quintile, household media exposure, big problem of distance to health facility, having high risky sexual behaviour and knowing the place of HIV testing were significant explanatory variables for spatial variation of premarital HIV testing among married women. While in the multilevel analysis, age, education level, religion, household media exposure, wealth index, khat chewing, previous history of HIV testing,age at first sex, HIV related knowledge, HIV related stigma, distance to health facility, and community level media exposure were associated with premarital HIV testing among married women.

CONCLUSIONS AND RECOMMENDATION

Premarital HIV testing had a significant spatial variation across regions of Ethiopia. A statistically significant clustering of premarital HIV testing was observed at Addis Ababa, Dire Dawa, North Tigray and some parts of Afar and Amhara regions. Therefore area based prevention and interventional strategies are required at cold spot areas to halt the role of heterosexual transmission in HIV burden. Moreover, the considering the spatial explanatory variables effect in implementations of these strategies rather than random provision of service would make regional health care delivery systems more cost-effective.

Use of "Strengthening Our Vows" Video Intervention to Encourage Negotiated Explicit Sexual Agreements in Zambian Heterosexual HIV Seroconcordant-Negative Couples

Negotiating sexual agreements in combination with couples' voluntary HIV counseling and testing (CVCT) may help further reduce HIV transmission in Zambian concordant HIV-negative couples (CNC). Though CVCT has been shown to reduce HIV transmission in CNC by 47%, approximately half of residual infections occur in this group. We developed a "Strengthening Our Vows" video session to foster communication and negotiation of explicit sexual agreements to reduce concurrent sexual exposures and prevent HIV transmission to the spouse due to unprotected, extramarital sex. CNC were recruited through CVCT services at five clinics in Lusaka and Ndola in 2016. Enrolled CNC attending the facilitated group video sessions were encouraged to discuss sexual agreements at home and return 1-2 weeks later for follow-up assessment. One-fourth of the 580 CNC returning reported a history of extramarital partners and/or a sexually transmitted infection (STI) prior to enrollment. More than 95% reported a friendly, supportive 15-60 min negotiation culminating in an agreement to remain monogamous or disclose sexual contacts and use condoms together until a repeat HIV test 30 days after an outside sexual exposure. Two-thirds of participants identified at least one threat to adherence of their agreements including alcohol use, financial pressures, travel, discord in the home, and post-partum or menstrual abstinence. CNC negotiated explicit sexual agreements to avoid exposure to HIV through concurrent partnerships and protect the spouse in the event of an outside sexual contact. Open communication was a consistent theme to facilitate mutual protective efforts. Long-term follow-up of HIV/STI incidence is ongoing to assess the impact of these agreements.Trial registration This sub-study is part of a trial retrospectively registered on ClinicalTrials.gov (Identifier: NCT02744586) on April 20, 2016.

Frequency of HIV serodifferent couples within TB-affected households in a setting with a high burden of HIV-associated TB

INTRODUCTION

Strong epidemiological links between human immunodeficiency virus (HIV) and tuberculosis (TB) may make household TB contact investigation an efficient strategy for HIV screening and finding individuals in serodifferent partnerships at risk of HIV and linking them to HIV prevention services. We aimed to compare the proportions of HIV serodifferent couples in TB-affected households and in the general population of Kampala, Uganda.

METHODS

We included data from a cross-sectional trial of HIV counselling and testing (HCT) in the context of home-based TB evaluation in Kampala, Uganda in 2016-2017. After obtaining consent, community health workers visited the homes of participants with TB to screen contacts for TB and offer HCT to household members ≥ 15 years. We defined index participants and their spouses or parents as couples. Couples were classified as serodifferent if confirmed by self-reported HIV status or by HIV testing results. We used a two-sample test of proportions to compare the frequency of HIV serodifference among couples in the study to its prevalence among couples in Kampala in the 2011 Uganda AIDS Indicator Survey (UAIS).

RESULTS

We included 323 index TB participants and 507 household contacts aged ≥ 18 years. Most index participants (55%) were male, while most (68%) adult contacts were female. There was ≥ 1 couple in 115/323 (35.6%) households, with most couples (98/115, 85.2%) including the index participant and spouse. The proportion of households with HIV-serodifferent couples was 18/323 (5.6%), giving a number-needed-to-screen of 18 households. The proportion of HIV serodifference among couples identified in the trial was significantly higher than among couples in the UAIS (15.7% vs. 8%, p = 0.039). The 18 serodifferent couples included 14 (77.8%) where the index participant was living with HIV and the spouse was HIV-negative, and 4 (22.2%) where the index partner was HIV-negative, while the spouse was living with HIV.

CONCLUSIONS

The frequency of HIV serodifference among couples identified in TB-affected households was higher than in the general population. TB household contact investigation may be an efficient strategy for identifying people with substantial exposure to HIV and linking them to HIV prevention services.

Predicting HIV infection in the decade (2005-2015) pre-COVID-19 in Zimbabwe: A supervised classification-based machine learning approach

The burden of HIV and related diseases have been areas of great concern pre and post the emergence of COVID-19 in Zimbabwe. Machine learning models have been used to predict the risk of diseases, including HIV accurately. Therefore, this paper aimed to determine common risk factors of HIV positivity in Zimbabwe between the decade 2005 to 2015. The data were from three two staged population five-yearly surveys conducted between 2005 and 2015. The outcome variable was HIV status. The prediction model was fit by adopting 80% of the data for learning/training and 20% for testing/prediction. Resampling was done using the stratified 5-fold cross-validation procedure repeatedly. Feature selection was done using Lasso regression, and the best combination of selected features was determined using Sequential Forward Floating Selection. We compared six algorithms in both sexes based on the F1 score, which is the harmonic mean of precision and recall. The overall HIV prevalence for the combined dataset was 22.5% and 15.3% for females and males, respectively. The best-performing algorithm to identify individuals with a higher likelihood of HIV infection was XGBoost, with a high F1 score of 91.4% for males and 90.1% for females based on the combined surveys. The results from the prediction model identified six common features associated with HIV, with total number of lifetime sexual partners and cohabitation duration being the most influential variables for females and males, respectively. In addition to other risk reduction techniques, machine learning may aid in identifying those who might require Pre-exposure prophylaxis, particularly women who experience intimate partner violence. Furthermore, compared to traditional statistical approaches, machine learning uncovered patterns in predicting HIV infection with comparatively reduced uncertainty and, therefore, crucial for effective decision-making.

Safer Sex Negotiation Among Ghanaian Women in Sexual Unions: Does Women's Household Decision-Making Capacity Matter?

Women's ability to negotiate for safer sex has been found to be dependent on their household decision making power. However, there is paucity of studies investigating the association between women's household decision making power and safer sex negotiation in Ghana. Thus, we examined the association between women's household decision making autonomy and safer sex negotiation among Ghanaian women in sexual unions using the 2014 Ghana's Demographic and Health Survey. Descriptive statistics, Chi-square test, and multivariable logistic regression models were performed. Statistical significance was set at p < .05 at 95% confidence interval. The results showed high prevalence of safer sex negotiation among women with high household decision-making capacity (91.6%). Compared to women with low household decision making autonomy, those with high autonomy in household decision making were more likely to negotiate for safer sex (aOR = 2.06; CI = 1.32-3.21). Women aged 25-34 were more likely to negotiate for safer sex compared to those aged 15-24 (aOR = 1.50; CI = 1.07-2.11). Higher odds of safer sex negotiation were found among women with comprehensive HIV and AIDS knowledge (aOR = 1.49; CI = 1.09-2.05), women who had tested for HIV (aOR = 1.57; CI = 1.27-1.95) and those exposed to newspaper (aOR = 1.80; CI = 1.17-2.78) compared to those who had no comprehensive knowledge on HIV and AIDS, those who had never tested for HIV and those who were not exposed to newspaper, respectively. However, women who belonged to other ethnic groups and the Islamic religion had lower odds of safer sex negotiation compared to Akans (aOR = 0.68; CI = 0.48-0.96) and Christian women (aOR = 0.63; CI = 0.46-0.85). Women empowerment programmes need to be intensified to enable Ghanaian women with low household decision making autonomy to negotiate for safer sex with their partners. Ghana could achieve the Sustainable Development Goals (SDGs), particularly, SDG 3.7 (universal access to sexual and reproductive health services), and SDG 5 (achieve gender equality and empower all women and girls) when household decision-making capacity among women is further strengthened.

Changing attitudes towards HIV testing and treatment among three generations of men in Cameroon: a qualitative analysis using the Fogg Behavior Model

INTRODUCTION

Men are less likely than women to test for HIV and promptly initiate antiretroviral treatment, resulting in advanced HIV disease and increased mortality rates among them.

METHODS

In-depth interviews were conducted with men and leaders in the west and central regions of Cameroon. Men were recruited from existing community groups and stratified by age: 21-30 years, 31-40 years, and 41 years and older. Community leaders were recommended by the community dialogue structure chairman. Interviews were conducted using a semi-structured guide in English or French, depending on the participant's preference. Transcripts were coded in the MAXQDA v.12 software and analyzed using thematic analysis and by age group. The Fogg Behavior Model was used to gain a deeper understanding of the different perceptions across all age groups.

RESULTS

Younger men (21-30 years) were generally more accepting of HIV testing, as it had become normative behavior. Although financial barriers could limit access, free testing was mentioned as a prompt to initiate HIV testing. The middle age men (31-40 years) had the most concerns about HIV testing interrupting their work day and recommended increasing testing locations and hours. The older men (41 + years) were the least motivated to get tested, citing worries about the impact on their social standing within the community. All age groups reported being motivated to begin treatment if they were found to be HIV-positive. Participants also provided insights regarding community HIV testing and treatment messaging. Younger and older men preferred to hear directly from qualified health professionals, but younger men noted that social media, radio, and TV could be utilized. Middle age men also identified TV and radio as effective mediums, if door-to-door messaging was not an option.

CONCLUSIONS

The study highlights important considerations when planning future information-sharing activities for HIV testing and treatment. Since lived experiences differ across generations and societal roles continue to change, not only should the content of messages differ among the generations, but the means of communication must also be considered to ensure the messages are conveyed through a trusted source.

Strategies to increase couples HIV testing and counselling in sub-Saharan Africa: a systematic review

INTRODUCTION

Couple HIV testing and counselling (CHTC) is associated with measurable benefits for HIV prevention and treatment. However, the uptake remains limited in much of sub-Saharan Africa, despite an expanded range of strategies designed to promote access.

METHODS

Following PRIMSA guidelines, we conducted a systematic review to characterize CHTC uptake strategies. Five databases were searched. Full-text articles were included if they were: conducted in sub-Saharan Africa during the study period (1980-2019), targeted heterosexual couples, reported at least one strategy to promote CHTC and provided a quantifiable measure of CHTC uptake. After the initial and full-text screening, key features of the studies were abstracted and synthesized.

RESULTS

Of the 6188 unique records found in our search, 365 underwent full-text review with 29 distinct studies included and synthesized. Most studies recruited couples through antenatal care (n = 11) or community venues (n = 8) and used provider-based HIV testing (n = 25). The primary demand creation strategies included home-based CHTC (n = 7); integration of CHTC into clinical settings (n = 4); distribution of HIV self-testing kits (n = 4); verbal or written invitations (n = 4); community recruiters (n = 3); partner tracing (n = 2); relationship counselling (n = 2); financial incentives (n = 1); group education with CHTC coupons (n = 1); and HIV testing at other community venues (n = 1). CHTC uptake ranged from negligible to nearly universal.

DISCUSSION

We thematically categorized a diverse range of strategies with varying levels of intensity and resources used across sub-Saharan Africa to promote CHTC. Offering CHTC within couples' homes was the most common approach, followed by the integration of CHTC into clinical settings. Due to heterogeneity in study characteristics, we were unable to compare the effectiveness across studies, but several trends were observed, including the high prevalence of CHTC promotion strategies in antenatal settings and the promising effects of home-based CHTC, distribution of HIV self-tests and integration of CHTC into routine health services. Since 2019, an updated literature search found that combining partner notification and secondary distribution of HIV self-test kits may be an additionally effective CHTC strategy.

CONCLUSIONS

There are many effective, feasible and scalable approaches to promote CHTC that should be considered by national programmes according to local needs, cultural context and available resources.

Preventing HIV and achieving pregnancy among HIV sero-different couples: Pilot study of a safer conception intervention in Zimbabwe

Safer conception services are needed to minimize HIV transmission among HIV sero-different couples desiring pregnancy. Few studies have evaluated the choices couples make when offered multiple safer conception methods or real-world method acceptability and effectiveness. We piloted a comprehensive safer conception program (Clintrials.gov identifier: NCT03049176) for HIV sero-different couples planning pregnancy in Zimbabwe to measure feasibility, method uptake, acceptability, pregnancy outcome, and HIV transmission. This study was not designed to compare rates of HIV transmission by safer conception method choice but rather to understand choices couples make when seeking to minimize risk of HIV transmission and maximize likelihood of pregnancy. Couples in this prospective, non-randomized study were given a choice of one or more currently available safer conception methods: antiretroviral therapy (ART) with monthly viral load (VL) monitoring for the HIV-positive partner (ART/VL), pre-exposure prophylaxis (PrEP) for the HIV-negative partner, vaginal insemination (VI) for couples with an HIV-positive woman, and semen washing (SW) for couples with an HIV-positive man. Couples were followed monthly for up to 12 months of pregnancy attempts, quarterly during pregnancy, and 12 weeks post-partum. At each visit, data on method use, urine for pregnancy testing, and blood for HIV antibody testing, or viral load if HIV-positive, were obtained. Infants born to HIV-positive women were tested for HIV at 6 and 12 weeks. Between March 2017 and June 2019, 46 individuals from 23 HIV sero-different partnerships were enrolled and followed. At enrollment, all couples chose ART/VL, and all couples chose at least one additional method; 74% chose PrEP, 36% chose SW, and 25% chose VI. During pre-pregnancy follow-up visits, three couples discontinued SW, and one couple discontinued VI; all four of these couples opted for ART/VL plus PrEP. Satisfaction with safer conception methods was high among those who chose ART/VL and PrEP. Twelve couples achieved pregnancy. There were no cases of HIV transmission to partners, and no infants tested positive for HIV. This safer conception program is feasible and acceptable, allowing sero-different couples to safely achieve pregnancy. Sero-different couples in Zimbabwe seek a combination of HIV prevention methods, particularly ART/VL plus PrEP. Trial Registration: Clintrials.gov, NCT03049176.

Fertility Desire and Associations with Condomless Sex, Antiretroviral Adherence, and Transmission Potential in a Cohort of Kenyan Women Living with HIV in Sero-discordant Relationships: A Mixed Methods Study

For women living with HIV (WLH) in serodiscordant partnerships, decisions about childbearing can challenge condom use and antiretroviral adherence. In a prospective cohort of 148 WLH in serodiscordant partnerships, 58 (39%) wanted more children in the future but were not currently trying to conceive (fertility desire), and 32 (22%) were currently trying to become pregnant (fertility intent). Detection of prostate specific antigen (PSA) in vaginal secretions, a marker for recent condomless sex, was lowest in women with fertility desire and highest in women with fertility intent. Detectable viral load followed a similar pattern. Risk of HIV transmission, when condomless sex and PSA detection occurred concurrently, was three to fourfold higher at visits with fertility intent compared to visits with fertility desire. Qualitative interviews underscored the importance women place on childbearing and suggested that they had limited information about the role of antiretroviral therapy in reducing sexual HIV transmission.

Non-cancer-specific survival in patients with primary central nervous system lymphoma: A multi-center cohort study

Objective

The study aimed to evaluate the non-cancer-specific death risk and identify the risk factors affecting the non-cancer-specific survival (NCSS) in patients with primary central nervous system lymphoma (PCNSL).

Methods

This multi-center cohort study included 2497 patients with PCNSL in the Surveillance, Epidemiology and End Results (SEER) database from 2007 to 2016, with a mean follow-up of 4.54 years. The non-cancer-specific death risk in patients with PCNSL and primary central nervous system diffuse large B-cell lymphoma (PCNS-DLBCL) was evaluated using the proportion of deaths, standardized mortality ratio (SMR), and absolute excess risk (AER). Univariate and multivariate competing risk regression models were utilized to identify the risk factors of NCSS.

Results

PCNSL was the most frequent cause of death in PCNSL patients (75.03%). Non-cancer-specific causes constituted a non-negligible portion of death (20.61%). Compared with the general population, PCNSL patients had higher risks of death from cardiovascular disease (CVD) (SMR, 2.55; AER, 77.29), Alzheimer's disease (SMR, 2.71; AER, 8.79), respiratory disease (SMR, 2.12; AER, 15.63), and other non-cancer-specific diseases (SMR, 4.12; AER, 83.12). Male sex, Black race, earlier year of diagnosis (2007-2011), being unmarried, and a lack of chemotherapy were risk factors for NCSS in patients with PCNSL and PCNS-DLBCL (all P < 0.05).

Conclusion

Non-cancer-specific causes were important competing causes of death in PCNSL patients. More attention is recommended to non-cancer-specific causes of death in the management of PCNSL patients.

Stigma of infidelity associated with condom use explains low rates of condom uptake: qualitative data from Uganda and Tanzania

Despite widespread messaging supporting male (external) condom use to prevent HIV in endemic settings, utilization of condoms is low across sub-Saharan Africa. A thorough understanding of barriers to condom use as a form of HIV prevention is necessary to reduce HIV transmission. Here, we present qualitative data from rural eastern Africa to explain low utilization of condoms among heterosexual adults. Focus groups and interviews were conducted in Tanzania and Uganda between 2016 and 2019. A content analysis approach was used to identify attitudes about condoms and factors related to use/non-use. We found that strategies such as abstinence and being faithful to one's partner are perceived as ideal but rarely achievable methods of HIV prevention. Condoms are used in the setting of "failure" to abstain or be faithful and are therefore stigmatized as markers of infidelity. As such, use within cohabiting and long-term relationships is low. Our data suggest that negative perceptions of condoms may stem from persistent effects of the formerly applied "ABC" HIV prevention approach, a public health messaging strategy that described A-abstinence, B-be faithful, and C-use a condom as tiered prevention tools. Condom uptake could increase if HIV prevention messaging acknowledges existing stigma and reframes condom use for proactive health prevention. These studies were approved by Weill Cornell Medicine (Protocols 1803019105 and 1604017171), Mbarara University of Science and Technology (Protocol 16/0117), Uganda National Council of Science and Technology (Protocol SS-4338), and the Tanzania National Institute for Medical Research (Protocol NIMR/HQ/R.8c/Vol.I/1330).

Male partner age, viral load, and HIV infection in adolescent girls and young women: evidence from eight sub-Saharan African countries

OBJECTIVE

We aimed to elucidate the role of partnerships with older men in the HIV epidemic among adolescent girls and young women (AGYW) aged 15-24 years in sub-Saharan Africa.

DESIGN

Analysis of Population-based HIV Impact Assessments in Eswatini, Lesotho, Malawi, Namibia, Tanzania, Uganda, Zambia, and Zimbabwe.

METHODS

We examined associations between reported partner age and recent HIV infection among AGYW, incorporating male population-level HIV characteristics by age-band. Recent HIV infection was defined using the LAg avidity assay algorithm. Viremia was defined as a viral load of more than 1000 copies/ml, regardless of serostatus. Logistic regression compared recent infection in AGYW with older male partners to those reporting younger partners. Dyadic analysis examined cohabitating male partner age, HIV status, and viremia to assess associations with AGYW infection.

RESULTS

Among 17 813 AGYW, increasing partner age was associated with higher odds of recent infection, peaking for partners aged 35-44 (adjusted odds ratio = 8.94, 95% confidence interval: 2.63-30.37) compared with partners aged 15-24. Population-level viremia was highest in this male age-band. Dyadic analyses of 5432 partnerships confirmed the association between partner age-band and prevalent HIV infection (male spousal age 35-44-adjusted odds ratio = 3.82, 95% confidence interval: 2.17-6.75). Most new infections were in AGYW with partners aged 25-34, as most AGYW had partners in this age-band.

CONCLUSION

These results provide evidence that men aged 25-34 drive most AGYW infections, but partners over 9 years older than AGYW in the 35-44 age-band confer greater risk. Population-level infectiousness and male age group should be incorporated into identifying high-risk typologies in AGYW.

Married women pre-marital HIV testing status in Ethiopia: Individual and community level factor analysis

Introduction

Marriage between serodiscordant individuals accounts for 65-85% of new infections. Pre-marital Human Immune Virus (HIV) testing opens the door for HIV infection prevention and control. There are no studies that have evaluated the coverage and factors influencing pre-marital HIV testing at the community level in Ethiopia.

Methods

This study was conducted using 10,008 samples of data extracted from Ethiopian demographic and health surveys (EDHS), 2016. To identify individual and community level factors a multi-level binary logistic regression model was used. Among fitted models, "full" model was taken as the best model. To declare the presence or absence of significant association with pre-marital HIV testing, a p-value < 0.05 with confidence interval (CI) was used.

Results

In Ethiopia, 21.4% (95% CI: 20.6, 22.2%) of study participants had pre-marital HIV testing. Age 35-49 years (AOR = 0.25; 95% CI: 0.09, 0.66), educated (AOR = 1.76; 95% CI: 1.17, 2.79), rich (AOR = 1.95; 95% CI: 1.13, 3.55), having media exposure (AOR = 1.54; 95% CI: 1.30, 4.71), and high community level literacy (AOR = 0.38; 95% CI: 0.22, 0.66) were factors significantly associated with pre-marital HIV testing.

Conclusion

The low coverage of pre-marital HIV testing in Ethiopia is insufficient to have a significant influence on the HIV/Acquired Immune Deficiency Syndrome (AIDS) epidemic. Information dissemination to create awareness about human rights and public health implications of pre-marital HIV testing áre necessary while it is made mandatory.

Vulnerability to human immunodeficiency virus infection and associated factors among married women in northwest Ethiopia: a cross-sectional study

PURPOSE

This study investigated the vulnerability to human immunodeficiency virus (HIV) infection and associated factors among married women in northwest Ethiopia.

METHODS

A community-based cross-sectional survey (n=657) was conducted from April 1 to 15,2020, in Metema District, northwest Ethiopia, in four randomly selected kebele administrations (thelowest level of local government). The inclusion criteria were married women aged ≥18 years residing with their husbands. Logistic regression analysis was conducted to identify factors associatedwith married women's vulnerability to HIV infection.

RESULTS

Participants were on average 33.70±9.50 years and nearly one-fourth (n=148, 22.5%) wereidentified as vulnerable to HIV infection (i.e., experienced sexually transmitted disease symptoms oran extramarital affair of either spouse within the past 12 months). Only 18.9% reported sexual communication with their husband. Respondents who did not discuss the risk of HIV infection withtheir husbands had fivefold odds of vulnerability (adjusted odds ratio [AOR], 5.02; 95% confidenceinterval [CI], 1.43-17.5). Those who did not have premarital sex (AOR, 0.20; 95% CI, 0.05-0.77)had no worries about HIV infection (AOR, 0.27; 95% CI, 0.08-0.94), sufficient income (AOR,0.56; 95% CI, 0.16-0.86), and less than four children (AOR, 0.69; 95% CI, 0.50-0.97) had decreased odds of being vulnerable to HIV than their counterparts.

CONCLUSION

Not discussing risk of HIV infection with husband was a major factor of vulnerabilityto HIV infection as was premarital sex, worry about HIV, income, and number of children. Measuresto strengthen couple's sexual communication and support economical stability is important for decreasing HIV vulnerability.

Uptake of premarital HIV testing and associated factors among women who had autonomous versus non autonomous marriage in Ethiopia: A nationwide study

Background

Premarital HIV testing offers an opportunity where prospective couples can know their HIV status before marriage to prevent both heterosexual and vertical transmission of HIV. Therefore, this study aimed to determine whether there is any significant difference in the prevalence of premarital HIV testing among women who had autonomous versus non-autonomous marriage, and to investigate the factors associated with premarital HIV testing among women who had autonomous versus non-autonomous marriage in Ethiopia.

Methods

Data were extracted from 2016 Ethiopia Demographic and Health Survey dataset and analyzed by using SPSS version 20. Frequencies and weighted percentage of the variables, and second-order Rao-Scott statistic were computed. Multivariable logistic regression analysis was used to identify factors between the two groups. An adjusted odds ratio with 95% confidence interval was considered to state statistically significant associations.

Result

From 9602 included sample, 4,043 (42.1%) of the women had autonomous marriage, and 5,559(57.9%) of the women had non-autonomous marriage. The prevalence of premarital HIV testing in Ethiopia among women who had autonomous marriage was 30.5% (95% CI: 27.7–33.4%) compared to 20.6% (95% CI: 18.5–22.8) among women who had a non-autonomous marriage. No differences in associated factors were found between women who had autonomous versus non autonomous marriage to uptake HIV testing. In both groups, residence in rural area, education attainment (primary, secondary, higher), media access, being rich and richest, knowing the places for HIV testing, chewing chat, and drinking alcohol were significantly predicts premarital HIV testing.

Conclusion

The study indicated that 10% more women in autonomous marriage tested for HIV relative to non-autonomous women whilst being an urban resident, educated, having access to media, household wealth and knowledge of testing facilities significantly predict HIV testing among women in Ethiopia. The paper recommends the Ethiopian government shall expand access to education among women while improving their access to media to enhance their socioeconomic wellbeing and health. Furthermore, it is better to inspire women to undergo autonomous marriage by fostering education in the community to enhance premarital HIV testing.

HIV-serodifferent couples' perspectives and practices regarding HIV prevention strategies: A mixed methods study

A substantial proportion of heterosexually acquired HIV infections in the U.S. occur between partners in primary relationships characterized by mixed HIV status. The U.S. Centers for Disease Control and Prevention have issued guidelines prioritizing HIV-serodifferent couples for primary HIV prevention, including treatment-as-prevention and pre-exposure prophylaxis (PrEP). Yet, very little research has been conducted to understand the perspectives and practices of HIV-serodifferent couples regarding HIV prevention strategies in the U.S. To help fill this gap, we conducted a mixed methods study with 27 mostly Black/African American and Latinx HIV-serodifferent heterosexual couples residing in New York City to explore their knowledge, attitudes, practices, and perspectives regarding combination HIV prevention, including condoms, PrEP and viral control. All couples expressed the desire to maintain viral suppression in the HIV-positive partner, which was not always achieved. There was considerable heterogeneity in the use of HIV prevention methods by couples; and several patterns emerged that were largely driven by gender and relationship dynamics. Female partners, in particular, expressed high levels of anxiety around transmission of HIV and thus desired multiple methods of protection. Healthcare providers should consider couples' psychosocial well-being, relationship quality, and other motivational factors when helping to tailor HIV preventative care for mixed-status couples.

Women's Economic Contribution, Relationship Status and Risky Sexual Behaviours: A Cross-Sectional Analysis from a Microfinance-Plus Programme in Rural South Africa

In sub-Saharan Africa, women bear a disproportionate burden of HIV/AIDS while also facing economic and gender inequalities. To explore the association of women's economic contribution and relationship status with risky sexual behaviour, this study analysed cross-sectional data from 626 women aged 22 to 84 in rural South Africa. All women were enrolled in a microfinance plus gender training programme (Intervention with Microfinance for AIDS and Gender Equity (IMAGE)). We used univariable and multivariable logistic regression to explore the associations of relationship status and women's household income contribution with inconsistent condom use, multiple sexual partners and transactional sex, respectively. We found that married, older women had the highest odds of inconsistent condom use, while those contributing all the household income had higher odds of multiple sexual partnerships, but lower odds of transactional sex compared to those with no contribution. Income contribution and relationship status have a nuanced relationship with sexual risk behaviours. Thus, economic strengthening interventions should target relevant vulnerable women while also addressing the broader social and economic drivers of risky sexual behaviour.

A national recruitment strategy for HIV-serodiscordant partners living in Canada for the Positive Plus One study: a mixed-methods study

Background

With the recent shift in focus to addressing HIV risk within relationships and couple-based interventions to prevent HIV transmission, successful recruitment of individuals involved in HIV-serodiscordant relationships is crucial. This paper evaluates methods used by the Positive Plus One (PP1) study to recruit and collect data on a diverse national sample of dyads and individuals involved in current or past HIV-serodiscordant relationships, discusses the strengths and limitations of the recruitment approach, and makes recommendations to inform the interpretation of study results and the design of future studies.

Methods

PP1 used a multi-pronged approach to recruit adults involved in a current or past HIV-serodiscordant relationship in Canada from 2016 to 2018 to complete a survey and an interview. Upon survey completion, index (first recruited) partners were invited to recruit their primary current HIV-serodiscordant partner. We investigated participant enrollment by recruitment source, participant-, relationship-, and dyad-level sociodemographic characteristics, missing data, and correlates of participation for individuals recruited by their partners.

Results

We recruited 613 participants (355 HIV-positive; 258 HIV-negative) across 10 Canadian provinces, including 153 complete dyads and 307 individuals who participated alone, and representing 460 HIV-serodiscordant relationships. Among those in current relationships, HIV-positive participants were more likely than HIV-negative participants to learn of the study through an ASO staff member (36% v. 20%, p < 0.001), ASO listserv/newsletter (12% v. 5%, p = 0.007), or physician/staff at a clinic (20% v. 11%, p = 0.006). HIV-negative participants involved in current relationships were more likely than HIV-positive participants to learn of the study through their partner (46% v. 8%, p < 0.001). Seventy-eight percent of index participants invited their primary HIV-serodiscordant partner to participate, and 40% were successful. Successful recruitment of primary partners was associated with longer relationship duration, higher relationship satisfaction, and a virally suppressed HIV-positive partner.

Conclusions

Our findings provide important new information on and support the use of a multi-pronged approach to recruit HIV-positive and HIV-negative individuals involved in HIV-serodiscordant relationships in Canada. More creative strategies are needed to help index partners recruit their partner in relationships with lower satisfaction and shorter duration and further minimize the risk of “happy couple” bias.

Condom use consistency among South African HIV serodiscordant couples following an HIV risk-reduction intervention

Background: Although there are several ways to transmit HIV, condomless sex remains the primary mode in sub-Saharan Africa, including South Africa, with KwaZulu-Natal Province being one of the epicentres of HIV infection. This study explored the use of condoms in serodiscordant couples who were exposed to an HIV-risk reduction intervention that aimed to improve condom use and reduce the spread of HIV.Methods: A Total of 30 couples completed a paper-based questionnaire on their demographics and general health at baseline and 3 months, plus a semi-structured questionnaire with four domains. An analysis of HIV knowledge, condom use, condom use attitudes and protection perceptions about how other serodiscordant couples behave was conducted following a 12-week HIV risk reduction intervention. Participants were randomised 2:1 into intervention and control groups.Results: Condom use increased from 55% at baseline to 73.7% (p = .0047) at 3 months for the intervention group and condom use in the last 7 days increased from 53% to 86% (p = .0117). For the control group, condom use remained low at the 3 months follow up period (p = .625). HIV knowledge improved significantly from baseline to 3 months for the intervention group (p < .0001), as well as the control group (p = .0005). Negative HIV condom use attitude scores in both groups decreased significantly from baseline to 3 months; intervention group (p = .0059) and control group (p = .0007).Conclusion: HIV knowledge and condom use improved significantly, while negative condom use attitudes and HIV protection perceptions decreased significantly following exposure to a risk-reduction intervention, suggesting that HIV preventive interventions should focus on partnership interventions.

Social Influence and Uptake of Couples HIV Testing and Counselling in KwaZulu-Natal, South Africa

Social influences may create a barrier to couples HIV testing and counselling (CHTC) uptake in sub-Saharan Africa. This secondary analysis of data collected in the 'Uthando Lwethu' randomised controlled trial used discrete-time survival models to evaluate the association between within-couple average 'peer support' score and uptake of CHTC by the end of nine months' follow-up. Peer support was conceptualised by self-rated strength of agreement with two statements describing friendships outside of the primary partnership. Eighty-eight couples (26.9%) took up CHTC. Results tended towards a dichotomous trend in models adjusted only for trial arm, with uptake significantly less likely amongst couples in the higher of four peer support score categories (OR 0.34, 95% CI 0.18, 0.68 [7-10 points]; OR 0.53, 95% CI 0.28, 0.99 [≥ 11 points]). A similar trend remained in the final multivariable model, but was no longer significant (AOR 0.59, 95% CI 0.25, 1.42 [7-10 points]; AOR 0.88, 95% CI 0.36, 2.10 [≥ 11 points]). Accounting for social influences in the design of couples-focused interventions may increase their success.

Conclusion

The geography and inter-community configuration of new sexual partnership formation in a rural South African population over fourteen years (2003-2016)

Understanding spatial configuration of sexual network structure is critical for effective use of HIV preventative interventions in a community. However, this has never been described at the population level for any setting in sub-Saharan Africa. We constructed the comprehensive geospatial sexual network among new heterosexual partnerships in rural KwaZulu-Natal, South Africa. In the Africa Health Research Institute (AHRI)'s population-based surveillance, we identified stable sexual partnerships among individuals (≥15 years) from 2003 to 2016. Sexual partnerships and residency were recorded via household surveys (every 4-6 months). We geolocated residents and migration events and mapped the geospatial linkages of sexual partners at the start of sexual partnerships. In a grid composed by 108 cells (nodes; 3kmx3km per cell) covering the surveillance area (438km2), we calculated the degree of connectivity and centrality of the nodes and examined their association with HIV prevalence and incidence per cell. Of 2401 new sexual partnerships, 21% (n = 495) had both partners living within the surveillance area at the start of sexual partnerships, and 76% (376/495) were linked to the geographic HIV cluster with high HIV prevalence identified in a peri-urban community. Overall, 57 nodes had at least one connection to another node. The nodes in the peri-urban cluster had higher connectivity (mean = 19, range: 9-32), compared to outside the cluster (6, range: 1-16). The node's degree of connectivity was positively associated with HIV prevalence of the cell (Pearson correlation coefficient = 0.67; p <0.005). The peri-urban cluster contained nine of the 10 nodes that composed of a single large central module in the community. About 17% of sexual partnerships (n = 421) were formed between a resident and a non-resident partner who out-migrated. Most of these non-resident partners lived in KwaZulu-Natal (86.7%), followed by Gauteng (9.7%), and the median distance between a resident and a non-resident partner was 50.1km (IQR: 23.2-177.2). We found that the peri-urban HIV cluster served as the highly connected central node of the network for sexual partnership formation. The network was also connected beyond the surveillance area across South Africa. Understanding spatial sexual network can improve the provision of spatially targeted and effective interventions.

A cluster randomized trial to reduce HIV risk from outside partnerships in Zambian HIV-Negative couples using a novel behavioral intervention, "Strengthening Our Vows": Study protocol and baseline data

BACKGROUND

Heterosexual couples contribute to most new HIV infections in areas of generalized HIV epidemics in sub-Saharan Africa. After Couples' Voluntary HIV Counseling and Testing (CVCT), heterosexual concordant HIV negative couples (CNC) in cohabiting unions contribute to approximately 47% of residual new infections in couples. These infections are attributed to concurrent sexual partners, a key driver of the HIV epidemic in Zambia.

METHODS/DESIGN

Ten Zambian government clinics in two of the largest cities were randomized in matched pairs to a Strengthening Our Vows (SOV) intervention or a Good Health Package (GHP) comparison arm. SOV addressed preventing HIV infection from concurrent partners and protecting spouses after exposures outside the relationship. GHP focused on handwashing; water chlorination; household deworming; and screening for hypertension, diabetes and schistosomiasis. CNC were referred from CVCT services in government clinics. Follow-up includes post-intervention questionnaires and outcome assessments through 60 months. Longitudinal outcomes of interest include self-report and laboratory markers of condomless sex with outside partners and reported sexual agreements. We present baseline characteristics and factors associated with study arm and reported risk using descriptive statistics.

RESULTS

The mean age of men was 32 and 26 for women. On average, couples cohabited for 6 years and had 2 children. Baseline analyses demonstrated some failures of randomization by study arm which will be considered in future primary analyses of longitudinal data. An HIV/STI risk factor composite was not different in the two study arms. Almost one-quarter of couples had an HIV risk factor at baseline.

DISCUSSION

In preparation for future biomedical and behavioral interventions in sub-Saharan Africa, it is critical to understand and decrease HIV risk within CNC.

Between a Rock and a Hard Place: How poverty and lack of agency affect HIV risk behaviors among married women in 25 African countries: A cross-sectional study

Background

Gender inequality and poverty exacerbate the burden of HIV/AIDS among women in Africa. AIDS awareness and educational campaigns have been inadequate in many countries and rates of HIV testing and adherence to condom use remains considerably low, especially among married women. We investigate whether higher HIV knowledge is equally effective in lowering risky behaviors among groups of women with different levels of wealth and agency.

Methods

Pooled data on 113 151 adult married women from Demographic and Health Surveys (DHS) in 25 African countries was used (2010 to 2016). Agency was defined as women’s ability to refuse sex and ask her partner to use a condom, plus have a role in decision making in household spending and health-related issues. The lowest tertile of DHS wealth index defined poverty. Questions about HIV prevention and mother-to-child transmission were used to create a scale for knowledge (0-5). Use of condom, HIV testing, absence of sexually transmitted disease (STD), and having one partner were dependent variables. Regression models investigated the effect of agency and knowledge as predictors of behaviors. Separate additional models were run to measure associations of each behavior with knowledge scores on groups of women divided by agency and poverty. Analyses were adjusted for demographic factors, history of pregnancy, wife-beating attitude, and country dummies.

Results

Significantly higher risk and lower level of protective factors exist for poor women who lack agency. Knowledge had positive associations with a better score in behavior, higher rate of condom use and testing for HIV both among poor and not poor women. When examining compound effects of agency and poverty, absence of agency reduces the positive effect of knowledge on lowering STD rate and overall behavior score among poor women. It also nullifies the effect of knowledge on condom use in both wealth groups.

Conclusion

Knowledge of HIV does not exert its potential protective effect when women live in poverty compounded with lack of agency. Success of anti-HIV programs should be tailored to dynamics of risk and sociocultural and economic context of target populations.

Couple oriented counselling improves male partner involvement in sexual and reproductive health of a couple: Evidence from the ANRS PRENAHTEST randomized trial

BACKGROUND

Male partner involvement (MPI) has been recognized as a priority area to be strengthened in Prevention of Mother to Child Transmission (PMTCT) of HIV. We explored the impact of Couple Oriented Counselling (COC) in MPI in sexual and reproductive health and associated factors.

METHOD

From February 2009 to October 2011, pregnant women were enrolled at their first antenatal care visit (ANC-1) and followed up until 6 months after delivery in the Mother and Child Center of the Chantal Biya Foundation within the randomized prenahtest multicentric trial. The MPI index was defined using sexual and reproductive health behaviour variables by using multiple correspondence analysis followed by mixed classification. Men were considered as highly involved if they had shared their HIV test results with their partner, had discussed on HIV or condom used, had contributed financially to ANC, had accompanied their wife to ANC or had practiced safe sex. Factors associated to MPI were investigated by the logistic model with GEE estimation approach.

RESULTS

A total of 484 pregnant women were enrolled. The median age of the women was 27 years (IQR: 23-31) and 55.23% had a gestational age greater than 16 weeks at ANC-1. Among them, HIV prevalence was 11.9% (95% CI: 9.0-15.4). The median duration of the women's relationship with their partner was 84 months (IQR: 48-120). MPI index at 6 months after delivery was significantly greater in the COC group than the classical counselling group (14.8% vs 8,82%; p = 0,043; Fig 1). The partners of the women who participated in the COC were more likely to be involved during follow up than others (aOR = 1.45; 95% CI = 1.00-2.10). Partners with no incoming activity (aOR = 2.90; 95% CI = 1.96-4.29), who did not used violence within the couple (aOR = 1.70; 95% CI = 1.07-2.68), and whose partner came early for ANC-1 (aOR = 1.37; 95% CI = 1.00-1.89) were more likely to be involved than others.

CONCLUSION

MPI remains low in stable couples and COC improves partner involvement. Our findings also support the need of strengthening outreach towards "stable" couples and addressing barriers. This could go a long way to improve PMTCT outcomes in Cameroon.

Genital Abnormalities, Hormonal Contraception, and Human Immunodeficiency Virus Transmission Risk in Rwandan Serodifferent Couples

BACKGROUND

We explored the role of genital abnormalities and hormonal contraception in human immunodeficiency virus (HIV) transmission among heterosexual serodifferent couples in Rwanda.

METHODS

From 2002 to 2011, HIV-serodifferent couples who were not using antiretroviral treatment were followed up, and sociodemographic and clinical data were collected, family planning provided, and HIV-negative partners retested. Couples were assessed for genital ulcers; nonulcerative genital sexually transmitted infection (STIs), including gonorrhea, chlamydia, and trichomoniasis; and non-STI vaginal infections, including bacterial vaginosis and candida. Multivariable models evaluated associations between covariates and HIV transmission genetically linked to the index partner.

RESULTS

Among 877 couples in which the man was HIV positive, 37 linked transmissions occurred. Factors associated with women's HIV acquisition included genital ulceration in the female partner (adjusted hazard ratio, 14.1) and nonulcerative STI in the male partner (8.6). Among 955 couples in which the woman was HIV positive, 46 linked transmissions occurred. Factors associated with HIV acquisition in men included nonulcerative STI in the female partner (adjusted hazard ratio, 4.4), non-STI vaginal dysbiosis (7.1), and genital ulceration in the male partner (2.6). Hormonal contraception use was not associated with HIV transmission or acquisition.

CONCLUSIONS

Our findings underscore the need for integrating HIV services with care for genital abnormalities. Barriers (eg, cost of training, demand creation, advocacy, and client education; provider time; and clinic space) to joint HIV/STI testing need to be considered and addressed.

The Magnetic Couples Study: protocol for a mixed methods prospective cohort study of HIV-serodifferent heterosexual couples' perspectives and use of pre-exposure prophylaxis (PrEP)

INTRODUCTION

HIV transmission within serodifferent heterosexual couples plays a key role in sustaining the global HIV pandemic. In the USA, transmission within established mixed-status couples accounts for up to half of all new HIV infections among heterosexuals. Oral HIV pre-exposure prophylaxis (PrEP) is a highly effective prevention method, although underutilised among serodifferent couples. Moreover, there is a dearth of research on US HIV-serodifferent couples' perspectives and use of PrEP, alone or in combination with other prevention methods. In this paper, we describe the study protocol for the Magnetic Couples Study, designed to fill critical knowledge gaps regarding HIV-serodifferent heterosexual couples' perspectives, experiences and utilisation of PrEP.

METHODS AND ANALYSIS

The Magnetic Couples Study is a mixed methods prospective cohort study designed to describe temporal patterns and identify determinants at multiple levels (individual, couple, HCF) of PrEP outcomes along the care continuum (PrEP awareness, linkage, uptake, retention and medication adherence) among HIV-serodifferent heterosexual couples residing in New York City. The study will also examine clinical management of PrEP, side effects and changes in sexual-related and substance use-related behaviour. A prospective cohort of 230 mixed-status couples already on oral PrEP was recruited, with quarterly assessments over 18 months; in addition, a cross-sectional sample of 150 mixed-status couples not currently on PrEP was recruited. In-depth semistructured qualitative interviews were conducted with a subsample of 25 couples. Actor-partner interdependence modelling using multilevel analysis will be employed for the analysis of longitudinal dyadic data. Framework analysis will be used to analyse qualitative data. A parallel convergent design will be used for mixed methods integration.

ETHICS AND DISSEMINATION

The study was approved by the University of Rochester Institutional Review Board (RSRB00052766). Study findings will be disseminated to community members and providers and to researchers and policy makers.

Antiretroviral Therapy Use and HIV Transmission Among Discordant Couples in Nonresearch Settings in Kigali, Rwanda

BACKGROUND

Antiretroviral therapy (ART) efficacy for HIV prevention among discordant couples has been demonstrated in clinical trials. Effectiveness outside of research settings is less well understood.

METHODS

HIV-discordant couples were enrolled in couples' testing and follow-up at 20 government clinics in Kigali from 2010 to 2014. We performed viral linkage analysis on seroconverting couples to determine infection sources (intracouple vs. extracouple). Antiretroviral therapy use in index partners was collected at baseline and during follow-up by self-report with verification of government medical records.

RESULTS

A total of 3777 HIV-discordant couples were identified and followed up at government health clinics. Fifty-four incident HIV infections were identified, of which 36 were confirmed linked to the index partner, 4 were unlinked, and 14 were unknown. Among the 50 linked or unknown transmission pairs, 38% occurred among couples in which the index partner was on ART (HIV incidence rate of 0.63/100 person-years), whereas 62% occurred among couples in which the index partner was not on ART (HIV incidence rate of 5.51/100 person-years; adjusted rate ratio, 6.9). HIV acquisition was higher in women than in men with non-ART using index partners (P < 0.001).

CONCLUSIONS

Couples in a government clinic couples' HIV testing and follow-up program in Rwanda had an 89% reduction in HIV incidence when index partners were using ART, slightly lower than efficacy estimates from randomized trials. Antiretroviral therapy for prevention should be prioritized for key populations including discordant couples identified via couples' voluntary counseling and testing, with increased efforts to improve uptake, adherence, and viral load monitoring.

Is Women's Tendency to Negotiate Safer Sex Another Opportunity for Intimate Partner Violence in Nigeria?

Husband's controlling and domineering attitudes have been shown to contribute to women's intimate partner violence experience in Nigeria. Some scholars have suggested that women's safer sex negotiation may create additional opportunity for incurring partner violence. The purpose of the current study was to test the possibility that married women's tendency to negotiate safer sex would contribute significant additional proportions of the variance in their experience of physical, sexual, and emotional violence. Using nationally representative data from a sample of married women in Nigeria (N = 19,360), three separate hierarchical regression analyses were performed to examine the contributions of husband's controlling and domineering attitudes and tendency to negotiate safer sex to the three types of violence experience. Regression analyses revealed that women whose husbands endorsed more controlling and domineering attitudes experienced more physical, sexual, and emotional violence. Furthermore, women with higher tendency to negotiate safer sex experienced more of all the forms of violence. After accounting for the influence of husband's controlling and domineering attitudes, regression analyses revealed that women's tendency to negotiate safer sex accounted for significant additional contributions of the variance in physical, sexual, and emotional violence experience. The additional contributions suggest that specific interventions may be needed for improving women's negotiation skills to reduce husband perpetrated violence risk.

Use of fertility awareness methods as a component of safer conception for women in HIV-serodifferent relationships in Kenya

Background

For couples affected by HIV, and serodifferent couples in particular, pregnancy desire is often juxtaposed against the risk of HIV transmission between the couple and the potential neonate leading to thinking about measures to minimize risk of HIV transmission. We assess the use of fertility awareness methods [FAM] and evaluate the drivers of alignment between indicators of fertility and sexual behavior among HIV-serodifferent couples desiring pregnancy.

Methods

HIV-serodifferent couples from Thika, Kenya were enrolled into an open-label pilot evaluation of safer conception strategies. Women responded to daily 7-item short message service [SMS] surveys on FAM and sexual activity. Menstrual cycles were categorized as having condomless sex aligned, not aligned, or partially aligned to the predicted peak fertility. We used binomial logit models with generalized estimating equations to assess alignment between condomless sex during peak fertility days and FAM results. We used Cox proportional hazards to compare pregnancy incidence among months with sex and peak fertility aligned and mis-aligned.

Results

A total of 6929 SMS surveys across 252 menstrual cycles of 65 women were included. Reporting “sticky” cervical mucus (adjusted odds ratio [aOR]: 2.25, 95% confidence interval [95% CI]: 1.30, 3.90) and positive ovulation prediction kit [OPK] result (aOR: 2.07, 95% CI: 1.11, 3.86) were associated with increased likelihood of alignment of condomless sex during peak fertility. Pregnancy incidence was statistically similar among periods with sex aligned and not aligned with peak fertility.

Conclusions

Among women engaged in a comprehensive safer conception program, a moderate percentage of women aligned condomless sex and predicted peak fertility days at least once. While FAM, particularly cervical mucus and OPK, are an inexpensive option for couples to consider using as a component of their safer conception strategies, antiretroviral-based strategies remain important to minimize risk.

Prevalence and factors associated with fertility desire among people living with HIV: A systematic review and meta-analysis

BACKGROUND

The fertility desire of people living with HIV (PLHIV) has been rising in the past decade. However, there are many studies among which the association remains controversial between the fertility desire of HIV-infected persons and antiretroviral therapy (ART), sex, marital status, and educational level.

METHODS

We performed a literature search of these meta-analyses in PubMed, the Cochrane Library, Web of Science and ScienceDirect in November 2019. We also reviewed references of eligible studies to complement the search. We used pooled odds ratios (ORs) and 95% confidence intervals (CIs) with a random-effects model and a fixed-effects model to estimate the association between fertility desire among PLHIV and ART, sex, age, marital status, educational level, and number of children. Subgroups with I square values (I2) and sensitivity analyses were performed to assess the heterogeneity and the stability of the overall ORs, respectively. We evaluated publication bias using Egger's test and a visual inspection of the symmetry in funnel plots.

RESULTS

In these meta-analyses 50 articles were included with 22,367 subjects. The pooled prevalence of fertility desire among PLHIV was estimated to be 42.04%. The pooled analyses showed that the fertility desire of PLHIV is associated with ART (OR = 1.11, 95% CI:1.00-1.23, P = 0.043), sex (OR = 1.51, 95% CI:1.10-2.09), age (OR = 2.65, 95% CI:2.24-3.14), marital status (OR = 1.34, 95% CI:1.08-1.66), educational level (OR = 0.85, 95% CI:0.73-1.00, P = 0.047) and the number of children (OR = 3.99, 95% CI:3.06-5.20). PLHIV who are on ART, are male, are younger than 30, are married/cohabiting, have received a secondary education or above, and are childless have a higher prevalence of fertility desire. The two factors of age and the number of children, in particular demonstrated a strong significant association with fertility desire. We found moderate heterogeneity in the meta-analyses of age and educational level and high heterogeneity in the meta-analyses of sex, marital status and number of children. Publication bias was detected in the meta-analyses of the association of fertility with sex and educational level.

CONCLUSION

This study demonstrates that the prevalence of fertility desire among HIV-infected people is 42.04%, and the fertility desire among PLHIV is associated with ART experience, sex, age, marital status, the number of children, and educational level. Since a majority of PLHIV are of reproductive age, it is necessary to support PLHIV in terms of their needs regarding reproductive decision-making. Through counseling and reproductive health care, further measures to prevent the horizontal and vertical transmission of HIV should be taken.

Rate of HIV Seroconversion Among Seronegative Male Partners Living with HIV Positive Women in Addis Ababa, Ethiopia, 2019: A Retrospective Cohort Study

Objective

This study aimed to assess rate of HIV seroconversion and predictors among seronegative male partners living with HIV-positive women in Addis Ababa, Ethiopia, 2019.

Methods

Institutional-based retrospective cohort was used to conduct the study. All eligible 227 sample medical records were used for the study. Kaplan–Meier analysis was used to estimate seroconversion time. Cox proportional-hazard regression was used to identify predictor variables.

Results

In this study, 227 seronegative male partners living with HIV-positive women were followed for 60 months retrospectively and 38 (16.7%) seroconversion was observed. The overall seroconversion rate was 6.4 (95%CI: 4.64–8.76) per 100 person-year observation. Time of antiretroviral therapy (ART) initiation, CD4 level, condom use, and having history of pregnancy after being diagnosed as discordant were identified significant predictors of seroconversion.

Conclusion

The risk of HIV transmission from seropositive partner to seronegative partner in a discordant couple is poorly controlled. Seronegative partners in discordant a couple can be seropositive at any time with influence of predictors unless proper protective measures, counseling, and follow-up are given emphasis.

HIV non-testing, perpetration of violence against women, and sexual risk-behaviour: A cross-sectional analysis of South African peri-urban township men

Despite HIV testing having improved globally, men remain disproportionately less likely to test for HIV. While violence against women (VAW) and HIV risk have a strong association among women, few studies explore men around VAW perpetration, risky-sexual behaviour, and HIV testing. Males aged 18-42 years were recruited from a peri-urban settlement near Johannesburg, South Africa. Data were from an endline of a trial. We used logistic regression to assess odds of non-HIV testing using STATA 13. At endline, 1508 men participated in the study. Of these nearly one-third (31.6%, n = 475) had not tested for HIV in the past year. HIV non-testing was significantly lower among men who were single, older, did not complete high school and were less food secure. VAW perpetration retained a significant association with HIV non-testing after controlling for socio-demographics (AOR = 0.73, 95%CI = 0.58-0.93). In multivariate models, HIV non-testing was also associated with inconsistent condom use (AOR = 0.64, 95%CI = 0.48-0.85), problem drinking (AOR = 0.72, 95%CI = 0.55-0.94) and reporting of all four risky sexual behaviours (AOR = 0.70, 95%CI = 0.49-1.01). Data suggests that one-third of men who never test for HIV in this setting may represent a high-risk group. Future campaigns could consider behaviour change around non-violence, relationship quality, and gender norms alongside HIV testing.

"I did not know about all these": Perceptions regarding safer conception methods by women living with HIV in Gaborone, Botswana

Various safer conception methods to limit HIV transmission risks can be offered in resource-constrained settings. However, implementation of safer conception services remains limited in many countries, including Botswana. Understanding perceptions about safer conception methods and the benefits and challenges to use can help with the development of policies, interventions, and service delivery models. Forty-five women living with HIV in the greater Gaborone, Botswana area participated in focus group discussions. Themes were analyzed using interpretive phenomenology. Despite low knowledge of specific safer conception methods that can be used to prevent transmission of HIV when trying to achieve pregnancy, there was noted interest in pre-exposure prophylaxis and vaginal insemination. Challenges to greater uptake were noted including a lack of knowledge about a range of SC methods, limited partner support and communication, provider stigma, health systems barriers, current policies, and the cultural acceptability of methods. Interventions will need to address these challenges and be responsive to the needs and reflect the realities of WLHIV who desire pregnancy in order for safer conception uptake to become a common practice.

Women's economic status and sexual negotiation: re-evaluation of the 'normative precedent' in Tanzania

Women's ability to negotiate the conditions and circumstances of sexual relations is central to their sexual and reproductive health, including mitigating HIV risk. In Africa, gender-based power imbalances constrain women's sexual agency. Research has suggested that among couples in sub-Saharan African countries, such as Uganda and Nigeria, sexual decision making is defined by a 'normative precedent' in the form of a set of rules and practices conferring sexual authority on men. Using qualitative data among women in paid work and among men, this study explored interpersonal relations and sexual negotiation in Tanzania. Data were collected in two sites, Dar es Salaam and Mbeya. The normative precedent for sexual decision making was universally understood by men and women. Women did not perceive paid work as giving them greater bargaining power in the domain of sex. In Mbeya, a high-HIV area, some women perceived that refusing sex would encourage men to have additional sexual partners, thus increasing their susceptibility to HIV. Other women, however, believed that suspicions about men's behaviour combined with accurate HIV knowledge, provided leverage for women to refuse sex. In both sites, challenges to the normative precedent were evident, particularly among younger men. Both men and women expressed a preference for equality in sexual decision making.

Factors Associated with Utilisation of Couple HIV Counselling and Testing Among HIV-Positive Adults in Kyoga Fishing Community Uganda, May 2017: Cross Sectional Study

Couple HIV counseling and testing (CHCT) is key in preventing heterosexual HIV transmission and achievement of 90-90-90 UNAIDS treatment targets by 2020. We conducted secondary data analysis to assess utilization of CHCT and associated factors using logistic regression. 58/134 participants (49%) had ever utilized CHCT. Disclosure of individual HIV results to a partner [aOR = 16; 95% CI: (3.6-67)], residence for > 1 < 5 years [aOR = 0.04; 95% CI (0.005-0.33)], and none mobility [aOR = 3.6; 95% CI (1.1-12)] were significantly associated with CHCT. Age modified relationship between CHCT and disclosure (Likelihood-ratio test LR chi2 = 4.2 (p value = 0.041). Disclosure of individual HIV results with a partner and residence for more than 1 year improved utilization of CHCT; mobility reduced the odds of CHCT. Interventions should target prior discussion of individual HIV results among couples and mobile populations to increase CHCT.

Determinants of intergenerational sexual relationships and HIV risk among South African women outpatients in Gauteng

Age-discrepant sexual relationships may place women at risk for HIV infection in South Africa. Results are based on medical records and case-control interview data of 889 sexually experienced women outpatients aged 15-29 in a Gauteng township. Women with partners at least ten years older (intergenerational) show an elevated chance of having an early sexual debut, concurrent and transactional partners, and intimate partner violence. Hardship during childhood including parental loss, food insecurity and abuse are related to age asymmetric relationships. HIV is two times more likely (aOR=1.96) with an intergenerational partner. Transactional sex increases the odds of HIV independently (aOR=1.76) as does intimate partner violence (aOR=1.6). To the extent that transactional and intergenerational sex overlap the chance of contracting HIV increases more than two-fold (uOR=4.57). Girls (15-19) with intergenerational partners face the highest chance of HIV (uOR=8.55) compared to other age groups. They are also five times more likely than controls to have lived with a cross-age partner. Our findings indicate there are multiple pathways emanating from childhood leading to women's choice of intergenerational partners, and the link to HIV is strongest among the youngest women.

Cost-effectiveness of integrated HIV prevention and family planning services for Zambian couples

OBJECTIVE

To present the incremental cost from the payer's perspective and effectiveness of couples' family planning counseling (CFPC) with long-acting reversible contraception (LARC) access integrated with couples' voluntary HIV counseling and testing (CVCT) in Zambia. This integrated program is evaluated incremental to existing individual HIV counseling and testing and family planning services.

DESIGN

Implementation and modelling.

SETTING

Fifty-five government health facilities in Zambia.

SUBJECTS

Patients in government health facilities.

INTERVENTION

Community health workers and personnel promoted and delivered integrated CVCT+CFPC from March 2013 to September 2015.

MAIN OUTCOME MEASURES

We report financial costs of actual expenditures during integrated program implementation and outcomes of CVCT+CFPC uptake and LARC uptake. We model primary outcomes of cost-per-: adult HIV infections averted by CVCT, unintended pregnancies averted by LARC, couple-years of protection against unintended pregnancy by LARC, and perinatal HIV infections averted by LARC. Costs and outcomes were discounted at 3% per year.

RESULTS

Integrated program costs were $3 582 186 (2015 USD), 82 231 couples received CVCT+CFPC, and 56 409 women received LARC insertions. The program averted an estimated 7165 adult HIV infections at $384 per adult HIV infection averted over a 5-year time horizon. The program also averted 62 265 unintended pregnancies and was cost-saving for measures of cost-per-unintended pregnancy averted, cost-per-couple-year of protection against unintended pregnancy, and cost-per-perinatal HIV infection averted assuming 3 years of LARC use.

CONCLUSION

Our intervention was cost-savings for CFPC outcomes and CVCT was effective and affordable in Zambia. Integrated couples-focused HIV and family planning was feasible, affordable, and leveraged HIV and unintended pregnancy prevention.

Uptake of long acting reversible contraception following integrated couples HIV and fertility goal-based family planning counselling in Catholic and non-Catholic, urban and rural government health centers in Kigali, Rwanda

BACKGROUND

When integrated with couples' voluntary HIV counselling and testing (CVCT), family planning including long acting reversible contraceptives (LARC) addresses prongs one and two of prevention of mother-to-child transmission (PMTCT).

METHODS

In this observational study, we enrolled equal numbers of HIV concordant and discordant couples in four rural and four urban clinics, with two Catholic and two non-Catholic clinics in each area. Eligible couples were fertile, not already using a LARC method, and wished to limit or delay fertility for at least 2 years. We provided CVCT and fertility goal-based family planning counselling with the offer of LARC and conducted multivariate analysis of clinic, couple, and individual predictors of LARC uptake.

RESULTS

Of 1290 couples enrolled, 960 (74%) selected LARC: Jadelle 5-year implant (37%), Implanon 3-year implant (26%), or copper intrauterine device (IUD) (11%). Uptake was higher in non-Catholic clinics (85% vs. 63% in Catholic clinics, p < 0.0001), in urban clinics (82% vs. 67% in rural clinics, p < 0.0001), and in HIV concordant couples (79% vs. 70% of discordant couples, p = .0005). Religion of the couple was unrelated to clinic religious affiliation, and uptake was highest among Catholics (80%) and lowest among Protestants (70%) who were predominantly Pentecostal. In multivariable analysis, urban location and non-Catholic clinic affiliation, Catholic religion of woman or couple, younger age of men, lower educational level of both partners, non-use of condoms or injectable contraception at enrollment, prior discussion of LARC by the couple, and women not having concerns about negative side effects of implant were associated with LARC uptake.

CONCLUSIONS

Fertility goal-based LARC recommendations combined with couples' HIV counselling and testing resulted in a high uptake of LARC methods, even among discordant couples using condoms for HIV prevention, in Catholic clinics, and in rural populations. This model successfully integrates prevention of HIV and unplanned pregnancy.

Factors associated with premarital HIV testing among married women in Ethiopia

Background

Premarital HIV testing is the key entry point in prevention, care, treatment, and support services, in which people learn their HIV status and its implications to make informed decisions about their health. This study was, therefore, conducted to identify factors associated with premarital HIV testing among married women in Ethiopia.

Methods

A cross-sectional study design was used, and secondary data analysis was done using 2016 Ethiopian demographic health survey (EDHS). Two-stage stratified cluster sampling technique was used. The data were analyzed by using SPSS version 20. Frequencies and weighted percentage of the variables, and second-order Rao-Scott statistic were computed. Multivariate logistic regression analysis was performed to control confounders and to identify predictors of premarital HIV testing. Adjusted odds ratio with 95% confidence interval was considered to declare statistically significant associations.

Result

The total sample comprised 9602 married women. In this study, the odds of premarital HIV testing were associated with being urban residents (AOR: 1.81; 95% CI: 2.74–5.20), attended primary education (AOR:1.54; 95%:1.27–1.87), secondary education (AOR:2.34; 95% CI:1.70–3.23), higher education (AOR:2.92; 95% CI:1.90–4.50), access to media (AOR: 1.44; 95% CI:1.20–1.76), being rich (AOR: 1.52; 95%CI:1.12–2.07), andrichest (AOR: 1.67;95%CI:1.15–2.44), known the place of HIV testing (AOR: 4.95; 95% CI:3.44–7.11), discriminatory attitude to PLHIV (AOR: 1.47; 95%CI:1.23–1.76), being khat chewer(AOR: 1.60;95%CI:1.11–2.31), and alcohol drinker (AOR: 1.55; 95% CI:1.27–1.90).

Conclusion

It is possible to conclude that being urban resident, attending education (primary, secondary, higher), media access, improved wealth index, knowing the places for HIV testing, chewing khat, drinking alcohol, and having discriminatory attitude towards PLHIV were positively associated with premarital HIV testing. The Ethiopian government needs to step up efforts to expand education for all Women. Advancing access to HIV testing for rural women may also increase premarital HIV testing services uptake. Further qualitative researches need to be done to assess the relationship between discriminatory attitude towards PLHIV and premarital HIV testing.

Preconception Care Uptake and Immediate Outcomes among Discordant Couples Accessing Routine HIV Care in Kenya

Introduction

A large proportion of new HIV infections occur within discordant partnerships making discordance a significant contributor to new HIV infections in Africa. Despite the role of preconception care for HIV discordant couples, there is little data on fertility desire and preconception care uptake. This study aimed at documenting fertility desire (desire to conceive), determining the uptake of preconception care, identifying HIV prevention strategies used during preconception care, and determining immediate conception outcomes among HIV discordant couples in Kenya.

Methods

We retrospectively extracted electronic medical record data on discordant couples at an HIV care discordant couples' clinic. We included data on couples who expressed a desire to conceive and were offered preconception care and followed up for 29 months. We collected data on sociodemographic characteristics, preconception prevention methods, and associated outcomes.

Results

Among couples, with male HIV-positive partners, there was a twofold likelihood of accepting preconception services (OR = 2.3, CI 95% (1, 1, 5.0)). A shorter discordant union was independently associated with the uptake of preconception services (OR = 0.92, CI 95% (0.86, 0.98)). The most used prevention intervention (38.5%) among discordant couples was a combination of pre-exposure prophylaxis (PrEP) by the uninfected partner, alongside HAART by the partner living with HIV. Pregnancy rates did not significantly (p  =  0.06) differ among those who took up preconception care versus those who did not. HIV-negative partners of couples who declined preconception care had a significantly (p  =  0.04) higher attrition from clinic follow-up. One confirmed seroconversion occurred; an HIV incidence rate of 0.19 per 100 person-years.

Conclusion

The study demonstrates the feasibility of implementing safe and effective preconception servicesas part of routine HIV care for discordant couples living in low resource settings. The provision and the utilisation of safer conception services may be hindered by the poor retention to follow-up and care of HIV-negative partners. This challenge may impede the expected benefits of preconception care as an HIV prevention intervention.

PrEP rollout in Africa: status and opportunity

Following recommendations by the World Health Organization in 2015, and key clinical trials, countries in sub-Saharan Africa, the region with the highest burden of human immunodeficiency virus (HIV), developed policies that incorporate pre-exposure prophylaxis (PrEP) into national HIV-prevention strategies. By the end of 2019, more than one third of people receiving PrEP globally were in Africa. Crucial understandings gained from early rollout among at-risk populations, such as HIV-serodiscordant couples, adolescent girls and young women, female sex workers, and men who have sex with men, include the importance of strategies for maintaining persistent adherence to PrEP and novel approaches to making PrEP services accessible, simplified and efficient. This Perspective will discuss the current status of these programs and how to further widen their implementation.

Motivational interviewing to promote long-acting reversible contraception among Rwandan couples wishing to prevent or delay pregnancy

BACKGROUND

Few family-planning programs in Africa base demand creation and service delivery on theoretical models. Motivational interviewing is a counseling modality that facilitates reflection on the benefits and disadvantages of a health outcome to encourage behavior change.

OBJECTIVES

We evaluate a couples-focused joint family-planning and HIV counseling intervention using motivational interviewing to enhance uptake of long-acting reversible contraception (Paragard copper intrauterine device or Jadelle hormonal implant) among Rwandan couples.

STUDY DESIGN

In this experimental study, couples receiving care at 8 government health clinics in Kigali, the capital city, were referred from a parent study of couples who did not want more children or wanted to wait at least 2 years for their next pregnancy. Long-acting reversible contraception methods were offered on site following joint HIV testing and family-planning counseling. At the first follow-up visit 1 month after enrollment in the parent study, couples who had not yet chosen a long-acting reversible contraception method were interviewed separately using motivational interviewing and then brought together and again offered long-acting reversible contraception.

RESULTS

Following motivational interviewing, 78 of 229 couples (34%) requested a long-acting reversible contraception method (68 implant and 10 intrauterine device). Long-acting reversible contraception uptake after motivational interviewing was associated with the woman being Catholic (vs Protestant/Muslim/other, adjusted odds ratio, 2.87, 95% confidence interval, 1.19-6.96, P = .019) or having an income (vs no income, adjusted odds ratio, 2.54, 95% confidence interval, 1.12-5.73, P = .025); the couple having previously discussed long-acting reversible contraception (adjusted odds ratio, 8.38, 95% confidence interval, 2.54-27.59, P = .0005); either partner believing that unplanned pregnancy was likely with their current method (adjusted odds ratio, 6.67, 95% confidence interval, 2.77-16.11, P < .0001); or that they might forget to take or make an appointment for their current method (adjusted odds ratio, 4.04, 95% confidence interval, 1.32-12.34, P = .014). Neither partner mentioning that condoms also prevent HIV/sexually transmitted infection was associated with long-acting reversible contraception uptake (adjusted odds ratio, 2.86, 95% confidence interval, 1.17-7.03, P = .022), as was the woman citing long-term duration of action of the implant as an advantage (adjusted odds ratio, 5.41, 95% confidence interval, 1.86-15.76, P = .002). The woman not listing any side effects or disadvantages of implants was associated with long-acting reversible contraception uptake (adjusted odds ratio, 5.42, 95% confidence interval, 2.33-12.59, P < .0001). Clinic location (rural vs urban), couple HIV status, and concerns about negative economic effects of an unplanned pregnancy were significant in bivariate but not multivariate analysis.

CONCLUSION

Encouraging couples to reflect on the benefits and disadvantages of long-acting reversible contraception methods, the likelihood of unplanned pregnancy with their current contraception, and the impact of an unplanned pregnancy is an effective motivational interviewing technique in family-planning counseling. One third of couples who did not want a pregnancy for at least 2 years but had not chosen a long-acting reversible contraception method when provided with standard family-planning counseling did so after motivational interviewing. Involving the male partner in family-planning discussions facilitates joint decision making about fertility goals and contraceptive choice. Combining family planning and joint HIV testing for couples allows targeted focus on dual-method use with discordant couples, who are advised to use condoms for HIV/sexually transmitted infection prevention along with a more effective contraceptive for added protection against unplanned pregnancy.

A couple-focused, integrated unplanned pregnancy and HIV prevention program in urban and rural Zambia

BACKGROUND

Zambia's total fertility rate (5 births per woman) and adult HIV prevalence (11.5%) are among the highest in the world, with heterosexual couples being the most affected group. Jointly counseling and testing couples for HIV has reduced up to 58% of new HIV infections in Zambian clinics. Married women using contraceptives in Zambia have a high (20%) unmet need for family planning and low (8.6%) uptake of cost-effective long-acting reversible contraceptives. We present an integrated counseling, testing, and family-planning program to prevent HIV and unplanned pregnancy in Zambia.

OBJECTIVE

The objective of this study was to integrate effective HIV prevention and family-planning services for Zambian couples.

STUDY DESIGN

A 3 year program (2013-2016) progressively integrated the promotion and provision of couples' voluntary HIV counseling and testing and long-acting reversible contraceptives. The program was based in 55 urban and 215 rural government clinics across 33 districts. In the first year, a couples' family-planning counseling training program was developed and combined with existing couples HIV counseling training materials. To avoid congestion during routine clinic hours, joint counseling services were initially provided on weekends, while nurses were trained in intrauterine device and hormonal implant insertion and removal during weekday family-planning services. Demand was created through mutual referral between weekend and weekday programs and by clinic staff, community health workers, and satisfied family-planning clients. When the bulk of integrated service training was completed, the program transitioned services to routine weekday clinic hours, ensuring access to same-day services. Performance indicators included number of staff trained, clients served, integrated service referrals, HIV infections averted, and unplanned pregnancies averted.

RESULTS

A stepwise approach trained high-performing service providers to be trainers and used high-volume clinics for practicum training of the next generation. In total, 1201 (391 urban, 810 rural) counselors were trained and served 120,535 urban and 87,676 rural couples. In urban clinics, 236 nurses inserted 65,619 long-acting reversible contraceptives, while in rural clinics, 243 nurses inserted 35,703 implants and intrauterine devices. The program prevented an estimated 12,869 urban and 8279 rural adult HIV infections, and 98,626 unintended urban pregnancies. In the final year, the proportion of clients receiving joint counseling services on weekdays rose from 11% to 89%, with many referred from within clinics including HIV testing and treatment services (32%), outpatient department (31%), family planning (16%), and infant vaccination (15%). The largest group of clients requesting long-acting reversible contraceptives (45%) did so after joint fertility goal-based counseling, confirming the high impact of this couple-focused demand creation approach. Remaining family-planning clients responded to referrals from clinic nurses (34%), satisfied implant/intrauterine device users (13%), or community health workers (8%).

CONCLUSION

Integrated HIV and unplanned pregnancy prevention can be implemented in low-resource public sector facilities. Combination services offered to couples mutually leverage HIV prevention and unplanned pregnancy prevention. The addition of long-acting reversible contraceptives is an important complement to the method mix available in government clinics. Demand creation in the clinic and in the community must be coordinated with a growing supply of well-trained providers.

HIV transmission between spouses living in Lu'an city, Anhui province, China: a longitudinal study

This study aims to investigate the human immunodeficiency virus (HIV) transmission rate in HIV serodiscordant couples, in addition to the relevant influencing factors. From January 1999 to August 2016, patients with HIV/AIDS (index cases) along with their fixed partners were registered and monitored to determine the rate of HIV transmission between couples, as well as relevant influencing factors. A total of 231 HIV-positive couples were investigated, of these, 45-negative (19.48%) partners were infected with HIV via sexual transmission prior to diagnosis of the first case detected in couples. After diagnosis, the transmission rate between spouses was 0.39 per 100 person-years (2/507.7), and the cumulative transmission rate was 1.08% (2/186), which was significantly lower than the transmission rate before diagnosis (χ² = 35.714, P < 0.001). Among the 119 HIV/AIDS patients who received antiretroviral therapy (ART), the transmission rate was 0 (0/119), whereas the transmission rate was 2.99% (2/67) in HIV/AIDS patients who did not receive ART. In addition, HIV transmission rate in serodiscordant couples was high prior to diagnosis of the index case. However, following diagnosis, the transmission rate was reduced, and the risk of transmission in the index case with antiviral treatment was null. Therefore, a prompt intervention in HIV discordant couples with ART of index case is vital to reduce the risk of HIV transmission.

Risk factors for HIV infection among married couples in Rakai, Uganda: a cross-sectional study

BACKGROUND

Although married couples can be at an elevated risk of HIV infection, few studies have explored the risk factors for HIV infection at the couple-level. We explored the risk factors for HIV infection among married couples in settings with differing HIV prevalence levels in Rakai, Uganda.

METHODS

This was a cross-sectional study conducted among 664 heterosexual couples living in three HIV prevalence strata (low: 9-11.2%; medium: 11.4-20% or high HIV prevalence: 21-43%) in Rakai District, south-western Uganda, between November 2013 and February 2014. Data were collected on socio-demographic and behavioural characteristics from all consenting adults and aggregated to allow for couple-level analyses. We conducted bivariate and multivariable Logistic regression to assess the factors that were independently associated with HIV infection among married couples. Data were analysed using STATA statistical software (version 14.1).

RESULTS

Of the 664 couples, 6.4% (n = 42) were in HIV-discordant relationships; 5.8% (n = 39) were in concordant HIV-positive relationships while 87.8% (n = 583) were in concordant HIV-negative relationships. At the bivariate analysis, we found that residing in a high HIV prevalence stratum, reporting extra-marital relations, age difference between partners and number of previous marriages were significantly associated with being part of an HIV infected couple. After adjusting for potential cofounders, living in a high HIV prevalence stratum (Adjusted OR [AOR] =2.31, 95% CI: 1.52, 3.52), being in a third or higher order relationship (AOR = 3.80, 95% CI: 2.30, 6.28), and engagement in extra-marital relations (AOR = 1.75; 95% CI: 1.19, 2.59) were associated with couple HIV infection. Individuals that had stayed together for six or more years had 28% odds of being part of an HIV infected couple (AOR = 0.28; 95%CI: 0.18, 0.43).

CONCLUSION

Living in a high HIV prevalence stratum, engagement in extra-marital relations and having a higher number of previous marriages were significant risk factors for HIV infection among married couples. Long marital duration was associated with reduced risk of HIV infection. Interventions that increase marital stability and those that promote pre-marital couples' HIV testing before marital formation can reduce HIV transmission risk among married couples in this setting.
