Key informant views on potential acceptability and feasibility of long-acting antiretroviral treatment for HIV in Kenya.

BACKGROUND: In 2020, 14% of diagnosed persons living with HIV (PLWH) in Kenya were not taking antiretroviral therapy (ART), and 19% of those on ART had unsuppressed viral loads. Long-acting antiretroviral therapy (LA-ART) may increase viral suppression by promoting ART uptake and adherence. We conducted key informant (KI) interviews with HIV experts in Kenya to identify product and delivery attributes related to the acceptability and feasibility of providing LA-ART to PLWH in Kenya. METHODS: Interviews were conducted via Zoom on potential LA-ART options including intra-muscular (IM) injections, subcutaneous (SC) injections, implants, and LA oral pills. KI were asked to discuss the products they were most and least excited about, as well as barriers and facilitators to LA-ART roll-out. In addition, they were asked about potential delivery locations for LA-ART products such as homes, pharmacies, and clinics. Interviews were recorded and transcribed, and data were analyzed using a combination of inductive and deductive coding. RESULTS: Twelve KI (5 women, 7 men) participated between December 2021 and February 2022. Overall, participants reported that LA-ART would be acceptable and preferable to PLWH because of fatigue with daily oral pills. They viewed IM injections and LA oral pills as the most exciting options to ease pill burden and improve adherence. KI felt that populations who could benefit most were adolescents in boarding schools and stigmatized populations such as sex workers. SC injections and implants were less favored, as they would require new training initiatives for patients or healthcare workers on administration. In addition, SC injections would require refrigeration and needle disposal after use. Some KI thought patients, especially men, might worry that IM injections and implants would impact fertility, given their role in family planning. Pharmacies were perceived by most KI as suboptimal delivery locations; however, given ongoing work in Kenya to include pharmacies in antiretroviral delivery, they recommended asking patients their views. CONCLUSION: There is interest and support for LA-ART in Kenya, especially IM injections and LA oral pills. Identifying patient preferences for modes and delivery locations and addressing misconceptions about specific products as they become available will be important before wide-scale implementation.

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.

"Whenever you need support, you first turn to the group": motivations and functions of WhatsApp groups for youth living with HIV.

Social support is a critical component of achieving positive health outcomes for youth living with HIV (YLWH). Mobile health (mHealth) has significant potential for providing social support to YLWH. However, little is known about the domains of social support most needed by YLWH which mHealth interventions might address. Drawing on the spontaneous creation of WhatsApp support groups by YLWH in Nairobi, Kenya, we characterized Kenyan YLWH's social support needs and potential roles of social media groups in meeting them. We conducted interviews and focus-groups with 68 YLWH, 24 caregivers and 20 healthcare workers, and observed two YLWH-led WhatsApp groups for 6 weeks. Youth reported that existing support systems, including family and healthcare workers, already provided informational and instrumental support. However, they emphasized unmet companionship and emotional support needs, leading to isolation, hopelessness, and medication adherence challenges. Participants identified connection with other YLWH as a unique source of emotional and companionship support that allowed them to feel more secure and less isolated. Interviews and observed WhatsApp chats demonstrated that WhatsApp groups were a desirable medium for companionship support that overcame barriers to in-person connection.

Psychosocial Factors, Condomless Sex, and Detectable Viral Load in HIV-Positive Women in Serodiscordant Couples in Nairobi, Kenya.

This prospective study of HIV-positive Kenyan women in serodiscordant couples examined relationships between psychosocial factors, viral suppression, and condomless sex. Participants were screened for alcohol use disorders and intimate partner violence (IPV) annually and depressive symptoms every 6 months. Prostate specific antigen (PSA) detection was used as a marker for condomless sex. A total of 151 participants contributed 349 person-years of follow-up. Hazardous/harmful alcohol use was associated with increased risk of detecting PSA in vaginal secretions (aRR 1.99, 95%CI 1.08-3.66, χ2 = 4.85 (1)), while IPV and depression were not. Events representing HIV transmission potential, where there was biological evidence of condomless sex at a visit with a detectable plasma viral load, were observed at 2% of visits. The high prevalence of IPV and association between alcohol use and sexual risk suggest the need for monitoring and support for these conditions as part of comprehensive HIV care for women.

Facilitated WhatsApp Support Groups for Youth Living With HIV in Nairobi, Kenya: Single-Arm Pilot Intervention Study.

BACKGROUND: Mobile technology can support HIV care, but studies in youth are limited. In 2014, youth receiving HIV care at several health care facilities in Nairobi, Kenya spontaneously formed peer support groups using the social media platform WhatsApp. OBJECTIVE: Inspired by youth-initiated groups, we aimed to evaluate the use of WhatsApp to deliver a social support intervention to improve HIV treatment and psychosocial outcomes in youth. We developed a facilitated WhatsApp group intervention (named Vijana-SMART), which was grounded in social support theory and guided by the design recommendations of youth living with HIV. This paper evaluates the intervention's acceptability and pre-post changes in health outcomes. METHODS: The intervention involved interactive WhatsApp groups facilitated by study staff for 6 months, with each group having approximately 25 members. Study staff sent weekly structured messages, and the message content was based on social support theory and encouraged unstructured peer-to-peer messaging and support. We conducted a single-arm pilot among 55 youth living with HIV aged 14-24 years recruited from a government health care facility serving a mixed-income area of Nairobi. At enrollment and follow-up, self-report questionnaires assessed acceptability; antiretroviral therapy (ART) information, motivation, and behavioral skills (IMB); depression; social support; stigma; resilience; and ART adherence. All participants received the intervention. We used generalized estimating equations (GEEs) clustered by participant to evaluate changes in scores from baseline to follow-up, and correlates of participant WhatsApp messaging. RESULTS: The median participant age was 18 years, and 67% (37/55) were female. Intervention acceptability was high. All participants reported that it was helpful, and 73% (38/52) sent ≥1 WhatsApp message. Messaging levels varied considerably between participants and were higher during school holidays, earlier in the intervention period, and among youth aged ≥18 years. IMB scores increased from enrollment to follow-up (66.9% to 71.3%; P<.001). Stigma scores also increased (8.3% to 16.7%; P=.001), and resilience scores decreased (75.0% to 70.0%; P<.001). We found no significant change in ART adherence, social support, or depression. We detected a positive association between the level of messaging during the study and the resilience score, but no significant association between messaging and other outcomes. Once enrolled, it was common for participants to change their phone numbers or leave the groups and request to be added back, which may present implementation challenges at a larger scale. CONCLUSIONS: Increased IMB scores following WhatsApp group participation may improve HIV outcomes. Increased stigma and decreased resilience were unintended consequences and may reflect transient effects of group sharing of challenging experiences, which should be addressed in larger randomized evaluations. WhatsApp groups present a promising and acceptable modality to deliver supportive interventions to youth living with HIV beyond the clinic, and further evaluation is warranted.

Prevalence and correlates of intimate partner violence among women with HIV in serodifferent relationships in Nairobi, Kenya.

BACKGROUND: Intimate partner violence (IPV) is a major public health problem and is the most common form of violence against women. Women with HIV in serodifferent relationships may be at an increased risk of IPV compared to women without HIV, hindering their ability to adhere to antiretroviral therapy, clinic appointments, and condom use during sex. This study assessed the prevalence and correlates of IPV in the past year among women with HIV in serodifferent relationships in Nairobi, Kenya. METHODS: This cross-sectional study included women with HIV in serodifferent relationships who were at least 18 years old and provided written informed consent. Their experience of physical, sexual, or emotional violence in the past year by the current partner was assessed using 13 questions adapted from the World Health Organization survey on violence against women. Standardized instruments were used to assess sociodemographic and behavioral factors. Associations between intimate partner violence and other variables were evaluated using log binomial regression models. RESULTS: Of the 159 women enrolled, 47 (29.6%, 95% CI 22.9-37.2%) reported IPV in the past year. Of these, 32 (68.1%) reported emotional, 27 (57.4%) physical, and 27 (57.4%) sexual violence. In the multivariate model, pregnancy (adjusted prevalence ratio [aPR] 2.14, 95% CI 1.09-4.20), alcohol use (minimal drinking aPR 1.91, 95% CI 1.10-3.33; moderate/severe drinking aPR 1.17, 95% CI 0.53-2.59), male partner controlling behavior (aPR 2.09, 95% CI 1.24-3.51), and past physical violence (aPR 1.93, 95% CI 1.22-3.05) remained significantly associated with a higher prevalence of IPV in the past year. CONCLUSION: This study identified a high prevalence of IPV in the past year among women with HIV in serodifferent relationships. Pregnant women and women who had experienced prior violence had a higher prevalence of IPV. These data highlight the need to screen for IPV during clinic visits, and to offer evidence based interventions to support women in serodifferent relationships who have experienced IPV.

Mobile technology access and use among youth in Nairobi, Kenya: implications for mobile health intervention design.

BACKGROUND: Social media can be used to support the health of underserved youth beyond clinical settings. Young people are avid users of social media, but estimates of smartphone access among youth in sub-Saharan Africa are lacking, making it difficult to determine context-appropriateness of online and social media interventions. METHODS: We conducted a cross-sectional observational survey assessing technology access and use among youth aged 14-24 receiving general outpatient or human immunodeficiency virus (HIV) care in three hospitals in Nairobi, Kenya. Correlates of smartphone access and social media use were evaluated by Poisson regression. RESULTS: Of 600 youth, 301 were receiving general outpatient care and 299 HIV care. Median age was 18 years. Overall, 416 (69%) had access to a mobile phone and 288 (48%) to a smartphone. Of those with smartphones, 260 (90%) used social media. Smartphone access varied by facility (40% at the sub-county hospital vs. 55% at the national referral hospital, P=0.004) and was associated with older age [65% in 20-24-year-old vs. 37% in 14-19-year-old, adjusted prevalence ratio (aPR) 1.58, 95% CI: 1.30-1.92], secondary vs. primary education (aPR 2.59, 95% CI: 1.76-3.81), and HIV vs. general outpatient care (aPR 1.18, 95% CI: 1.01-1.38). Social media use was similarly associated with facility, older age, higher education, and male gender. CONCLUSIONS: These data suggest that smartphone-based and social media interventions are accessible in Nairobi, Kenya, in the general population and youth living with HIV, and most appropriate for older youth. Intervention developers and policymakers should consider smartphone and social media interventions as candidates for youth health programs, while noting that heterogeneity of access between and within communities requires tailoring to the specific intervention context to avoid excluding the most vulnerable youth.

Experiences With Safer Conception Services for HIV-Serodiscordant Couples at a Referral Hospital in Nairobi, Kenya.

Human immunodeficiency virus-serodiscordant couples are an important source of new HIV infections in Africa. When trying to conceive, uninfected partners may be at high risk of infection if the infected partner is not virally suppressed. Multiple strategies targeting safer conception exist, but these services are limited. However, when services are available and used, serodiscordant couples can be protected from HIV transmission, and safe to have children if desired. To successfully introduce, integrate, promote, and optimize the service delivery of safer conception with HIV care, it is crucial to understand how HIV-serodiscordant couples perceive and experience these services. Further, viral load monitoring can be critical to safer conception, but there is limited literature on how it informs the decision of the partners about conception. This qualitative study describes the knowledge, perceptions, and experiences of both safer conception services and viral load monitoring among 26 HIV-serodiscordant couples seeking safer conception care at a referral hospital in Nairobi, Kenya. In-depth interviews of HIV-serodiscordant couples were conducted from April to July 2017, and transcripts were analyzed to identify the themes central to the experience of safer conception services of couples and viral load monitoring. Serodiscordant couples reported success in using some of the safer conception methods and had positive experiences with healthcare providers. However, despite using the services, some were concerned about HIV transmission to the seronegative partner and baby, while others faced challenges when using pre-exposure prophylaxis (PrEP) and vaginal insemination. Overall, their motivation to have children overcame their concern about HIV transmission, and they welcomed discussions on risk reduction. Moreover, supportive clinic staff was identified as key to facilitating trust in safer conception methods. Furthermore, viral load monitoring was identified as integral to safer conception methods, an emerging theme that requires further evaluation, especially where routine viral load monitoring is not performed. In conclusion, healthcare providers offering safer conception services should build trust with couples, and recognize the need for continual couple counseling to encourage the adoption of safer conception services.

Late antiretroviral refills and condomless sex in a cohort of HIV-seropositive pregnant and postpartum Kenyan women.

INTRODUCTION: The postpartum period can be challenging for women living with HIV. Understanding how the postpartum period impacts ART adherence and condomless sex could inform the development of comprehensive sexual and reproductive health and HIV services tailored to the needs of women living with HIV during this critical interval. METHODS: In a longitudinal cohort study of HIV-seropositive Kenyan women, late ART refills and self-reported condomless sex were compared between the woman's pregnancy and the postpartum period. Analyses were conducted using generalized estimating equations and adjusted for alcohol use, depressive symptoms, intimate partner violence (IPV), and having a recent regular partner. Effect modification was explored for selected variables. RESULTS AND DISCUSSION: 151 women contributed visits. Late ART refills occurred at 7% (32/439) of pregnancy visits compared to 18% (178/1016) during the postpartum period (adjusted relative risk [aRR] 2.44, 95% confidence interval [CI] 1.62-3.67). This association differed by women's education level. Women with ≥8 years of education had late ART refills more during the postpartum period than pregnancy (aRR 3.00, 95%CI 1.95-4.62). In contrast, in women with <8 years of education, late ART refills occurred similarly during pregnancy and the postpartum period (aRR 0.88, 95%CI 0.18-4.35). Women reported condomless sex at 10% (60/600) of pregnancy visits compared to 7% (72/1081) of postpartum visits (aRR 0.76, 95%CI 0.45-1.27). This association differed by whether women had experienced recent IPV. Women without recent IPV had a significant decline in condomless sex from pregnancy to postpartum (aRR 0.53, 95%CI 0.30-0.95) while women with recent IPV had no significant change in condomless sex from pregnancy to postpartum (aRR 1.76, 95%CI 0.87-3.55). CONCLUSION: Improved support for ART adherence during the postpartum period and addressing IPV to limit condomless sex could improve HIV treatment and prevention outcomes for HIV-seropositive women as well as their infants and sexual partners.
