RESUMEN

Men in sub-Saharan Africa are underrepresented in antiretroviral therapy (ART) programs. Our secondary analysis of 40 in-depth interviews with Malawian men living with HIV examined barriers and facilitators for ART initiation versus retention. Interviewees included men who never initiated or initiated ART late (initiation respondents, n = 19); and men who initiated ART but were late for an appointment (retention respondents, n = 21). Transcribed interviews were coded using deductive and inductive coding techniques and analyzed using constant comparison methods. Long wait times, frequent facility visits, and insufficient in-clinic privacy were barriers for initiation and retention. Poor knowledge of ART was primarily a barrier for initiation; unexpected travel was a barrier for retention. Key facilitators for initiation and retention included previous positive experiences with health facilities. Having examples of successful men using ART primarily facilitated initiation; support from spouses and male peers facilitated retention. Results may inform interventions to increase men's engagement in ART services.

RESUMEN

We conducted a programmatic, observational cohort study with mother-infant pairs (MIPs) enrolled in prevention-of-mother-to-child-transmission (PMTCT) programs in Malawi to assess the feasibility and potential HIV-related benefits of integrating Early Childhood Development (ECD) services into PMTCT programs. Six health facilities were included in the intervention. We offered ECD counseling from the WHO/UNICEF Care for Child Development package in PMTCT waiting spaces while MIPs waited for PMTCT and broader treatment consultations. Primary outcomes were mothers' retention in HIV care at 12 months and infant HIV testing at 6 weeks and 12 months after birth. Routine facility-level data from six comparison health facilities were collected as an adhoc standard of care comparison and used to calculate the cost of delivering the intervention. A total of 607 MIPs were enrolled in the integrated ECD-PMTCT intervention between June 2018 and December 2019. The average age of MIPs was 30 years and 7 weeks respectively. We found that 86% of mothers attended ≥ 5 of the 8 ECD sessions over the course of 12 months; 88% of intervention mothers were retained in PMTCT versus 59% of mothers in comparison health facilities, and 96% of intervention infants were tested for HIV by six weeks compared to 66% of infants in comparison health facilities. Costing data demonstrated the financial feasibility of integrating ECD and PMTCT programs in government health facilities in Malawi. Integrating ECD into PMTCT programs was feasible, acceptable, resulted in better programmatic outcomes for both mothers and infants. Further investigation is required to determine optimal delivery design for scale-up.

RESUMEN

This study examines baseline associations between alcohol use and HIV sexual risk among a cohort of HIV-uninfected pregnant women (n = 1201) residing in a high HIV burdened community in Cape Town, South Africa. Alcohol use was measured using a modified version of the Alcohol Use Disorder Identification Test (AUDIT). HIV sexual risk was measured through a composite variable of four risk factors: diagnosis with a STI, self-report of > 1 recent sex partners, partner HIV serostatus (unknown or HIV+) and condomless sex at last sex. Any past year alcohol use prior to pregnancy was reported by half of participants (50%); 6.0% reported alcohol use during pregnancy. Alcohol use prior to pregnancy was associated with increased odds of being at high risk of HIV (aOR = 1.33, 95% CI 1.05-1.68, for 2 risks and aOR = 1.47, 95% CI 0.95-2.27 for 3 risks). In addition to reducing alcohol use, several other strategies to address HIV sexual risk were identified. Evidence-based interventions to address alcohol use and other HIV sexual risk behaviors during pregnancy in South Africa are desperately needed. Qualitative work exploring individual and community level drivers of alcohol use among pregnant and breastfeeding women in this setting could support development of a culturally tailored intervention to address these issues in this population.

RESUMEN

Pregnant women in sub-Saharan Africa are at high risk of HIV acquisition and require effective methods to prevent HIV. In a cohort of pregnant women offered Pre-exposure prophylaxis (PrEP), we evaluate the relationship between internalized and anticipated stigma and PrEP initiation at first antenatal visit, 3-month continuation and adherence using multivariable logistic regression. High internalized and anticipated PrEP stigma are associated with lower PrEP care initiation at first antenatal visit (aOR internalized stigma = 0.06; 95% CI = 0.03-0.11 and aOR anticipated stigma = 0.55; 95% CI = 0.31-1.00) compared to women with low reported stigma, after controlling for covariates. Women whose partners have not been tested for HIV or whose serostatus remains unknown have 1.6-times odds of PrEP retention at 3-months compared to women whose partners have been tested (aOR = 1.60; 95% CI = 1.02-2.52) after adjusting for covariates. PrEP counseling and maternal PrEP interventions must consider individual- and relational-level interventions to overcome anticipated PrEP stigma and other barriers to PrEP initiation and adherence.

RESUMEN

Cisgender women, particularly pregnant and postpartum women in Eastern and Southern Africa, face an unacceptably high risk of HIV acquisition. Oral pre-exposure prophylaxis (PrEP) is an effective HIV prevention intervention that can reduce HIV acquisition and vertical transmission. In this qualitative study, we interviewed 21 postpartum women from Cape Town, South Africa who initiated PrEP during pregnancy and who self-reported low PrEP adherence or missed > 1 PrEP follow-up collection. We identified multiple overlapping barriers to PrEP continuation and/or adherence. Individual factors included forgetting to take PrEP daily, being away from home when PrEP should be taken, anticipated stigma and limited disclosure of PrEP use. Women also reported pill-related factors such as side effects and having to take PrEP in addition to other tablets during pregnancy and the postpartum period. Facility-related barriers included logistics around PrEP collection especially when not in antenatal care, as well as transport and financial barriers.

RESUMEN

BACKGROUND: HIV incidence among pregnant and postpartum women remains high in South Africa. Pre-exposure prophylaxis (PrEP) use remains suboptimal in this population, particularly during the postpartum period when women's engagement with routine clinic visits outside PrEP decreases. Key barriers to sustained PrEP use include the need for ongoing contact with the health facility and suboptimal counseling around effective PrEP use. METHODS: Stepped Care to Optimize PrEP Effectiveness in Pregnant and Postpartum women (SCOPE-PP), is a two-stepped unblinded, individually randomized controlled trial (RCT) that aims to optimize peripartum and postpartum PrEP use by providing a stepped package of evidence-based interventions. We will enroll 650 pregnant women (> 25 weeks pregnant) who access PrEP at a busy antenatal clinic in Cape Town at the time of recruitment and follow them for 15 months. We will enroll and individually randomize pregnant women > 16 years who are not living with HIV who are either on PrEP or interested in starting PrEP during pregnancy. In step 1, we will evaluate the impact of enhanced adherence counselling and biofeedback (using urine tenofovir tests for biofeedback) and rapid PrEP collection (to reduce time required) on PrEP use in early peripartum compared to standard of care (SOC) (n = 325 per arm). The primary outcome is PrEP persistence per urine tenofovir levels and dried blood spots of tenofovir diphosphate (TFV-DP) after 6-months. The second step will enroll and individually randomize participants from Step 1 who discontinue taking PrEP or have poor persistence in Step 1 but want to continue PrEP. Step 2 will test the impact of enhanced counseling and biofeedback plus rapid PrEP collection compared to community PrEP delivery with HIV self-testing on PrEP use (n = up to 325 postpartum women). The primary outcome is PrEP continuation and persistence 6-months following second randomization (~ 9-months postpartum). Finally, we will estimate the cost effectiveness of SCOPE-PP vs. SOC per primary outcomes and disability-adjusted life-years (DALYs) averted in both Step 1 and 2 using micro-costing with trial- and model-based economic evaluation. DISCUSSION: This study will provide novel insights into optimal strategies for delivering PrEP to peripartum and postpartum women in this high-incidence setting. TRIAL REGISTRATION: NCT05322629 : Date of registration: April 12, 2022.

RESUMEN

PrEP is safe and effective but requires adherence during potential HIV exposure, yet the facilitators of long-term maternal adherence are not well understood. We conducted semi-structured interviews with 25 postpartum women who reported high adherence (PrEP use ≥ 25 days in last 30-days and never missed a PrEP prescription in pregnancy/postpartum period) within a PrEP service for pregnant and postpartum women. A thematic approach guided an iterative process of coding and analysis. Themes identified as drivers of optimal PrEP use were HIV risk perception, mainly because of partner's behaviors and unknown serostatus, and a strong desire to have a baby free of HIV. Reported disclosure of PrEP use facilitated PrEP adherence. Women discussed having partner and family support, which included reminders to take PrEP daily. Primary barriers were anticipated or experienced stigma, overcome through education of partners and family about PrEP. Pregnant women experienced transient side-effects, but found ways to continue, including taking PrEP at night. PrEP programs for pregnant and postpartum women should integrate strategies to assist women with realistic appraisals of risk and teach skills for disclosure and securing support from significant others.


RESUMEN: La profilaxis Pre-exposición (PrEP, siglas en inglés) es segura y eficaz, pero requiere adherencia durante una posible exposición al VIH; sin embargo, no se conocen bien los factores que facilitan la adherencia materna a largo plazo. Realizamos entrevistas semiestructuradas con 25 mujeres en posparto que informaron un alto cumplimiento (uso de PrEP> 25 días en los últimos 30 días y nunca omitieron una receta de PrEP en el embarazo y período posparto) dentro de un servicio de PrEP para mujeres embarazadas y posparto. Un enfoque temático guio un proceso iterativo de codificación y análisis. Los temas identificados como impulsores del uso óptimo de la PrEP fueron la percepción del riesgo de VIH, principalmente debido a los comportamientos de la pareja y el estado serológico desconocido, y un fuerte deseo de tener un bebé libre de VIH. La divulgación informada del uso de PrEP facilitó la adherencia a la PrEP. Las mujeres hablaron sobre el apoyo de su pareja y familia, incluidos recordatorios para tomar la PrEP cada dia. Las barreras primarias fueron el estigma anticipado o experimentado, superado a través de la educación de los socios y familiares sobre la PrEP. Las mujeres embarazadas experimentaron efectos secundarios transitorios, pero encontraron formas de continuar, incluida la toma de PrEP por la noche. Los programas de PrEP para mujeres embarazadas y posparto deben integrar estrategias para ayudar a las mujeres con evaluaciones realistas del riesgo y enseñar habilidades para la divulgación y obtener el apoyo de otras personas importantes.

RESUMEN

KEY MESSAGES: Benefits for mothers and children can be achieved through the successful integration of an early childhood development programme into PMTCT Option B+ services in Malawi.Our study based on in-depth interviews with 62 mothers indicated that such an approach is feasible and acceptable.Participating mothers reported that the integration of the early childhood development component improved their confidence and they believed it improved their parenting;led to improved relationships with health care providers;increased the engagement of fathers and support from others in the family;helped mothers build a new social network and support system through the peer engagement components;reduced the risk of stigmatization in the health care setting.

RESUMEN

BACKGROUND: HIV-positive mothers who face the dual burden of HIV-positive status and motherhood, may benefit from holistic services that include early childhood development (ECD). We evaluated the acceptability and impact of integrated ECD-PMTCT interventions for mothers and their children. METHODS: We implemented an integrated ECD-PMTCT intervention in 4 health facilities in Malawi for HIV-positive mothers and their infants. WHO/UNICEF Care for Child Development (CCD) education and counseling sessions were offered during routine PMTCT visits between infant age 1.5-24 months. From June-July 2019, we conducted in-depth interviews with 29 mothers enrolled in the intervention for ≥6 months across 4 health facilities. The interview guide focused on perceived impact of the intervention on mothers' ECD and PMTCT practices, including barriers and facilitators, and unmet needs related to the program. Data were coded and analyzed using constant comparison methods in Atlas ti.8. RESULTS: The vast majority of mothers believed the ECD-PMTCT intervention improved their overall experience with the PMTCT services, strengthened their relationship with providers, and excited and motivated them to attend PMTCT services during the postpartum period. Unlike prior experience, mothers felt more welcome at the health facility, and looked forward to the next visit in order to interact with other mothers and learn new ECD skills. Mothers formed new social support networks with other mothers engaged in ECD sessions, and they provided emotional and financial support to one another, including encouragement regarding ART adherence. Mothers believed their infants reached developmental milestones faster compared to non-intervention children they observed at the same age, and they experienced improved engagement in caregiving activities among male caregivers. Nearly half of women requested additional support with depression or anxiety, coping mechanisms to deal with the stresses of life, or support in building positive dynamics with their male partner. CONCLUSION: The integrated ECD-PMTCT intervention improved mother's experiences with PMTCT programs and health care providers, increased ECD practices such as responsive and stimulating parenting, and created social support networks for women with other PMTCT clients.

RESUMEN

Pre-exposure prophylaxis (PrEP) in pregnancy can reduce HIV incidence and vertical transmission. Healthcare providers (HCPs) play a critical role in delivering PrEP in antenatal care but little is known about HCP knowledge and attitudes about PrEP in pregnancy. We conducted a qualitative study in two healthcare facilities to assess HCPs' PrEP knowledge and perspectives relating to HIV prevention in pregnant women. Between January-March'19, we administered in-depth interviews among antenatal HCPs. We utilized a constant comparison approach to identify major qualitative findings. We enrolled 35 female HCPs (median age=43yrs. Fewer than half of HCPs had heard of PrEP before. Of those who had heard of PrEP, most felt that it was safe to take during pregnancy. Most HCPs described inaccurate PrEP knowledge regarding effectiveness, and most who knew about PrEP lacked clinical detail. HCPs highlighted important potential barriers to maternal PrEP use including: fear that PrEP may be unsafe, or belief that women must talk to partners/parents before initiating PrEP. Facilitators include good knowledge about serodiscordancy and vulnerability to seroconversion in pregnancy and desire to help women gain control overHIV prevention. We recommend integrating PrEP training into HIV testing and PMTCT nurse training to improve counseling and maternal PrEP delivery.

RESUMEN

BACKGROUND: Expedited Partner Therapy (EPT) has been shown to improve treatment outcomes among heterosexual partners of individuals with curable sexually transmitted infections (STIs). Although the use of EPT with men who have sex with men (MSM) has been debated, due to the potential for missed opportunities to diagnose unidentified cases of HIV and syphilis infection in symptomatic partners, increases in partner notification (PN) resulting from use of EPT may promote testing and treatment of otherwise unidentified partners. We assessed the impact of EPT on self-reported PN among MSM in Peru with gonorrheal (GC) and/or chlamydial (CT) infection. METHODS: We enrolled 173 MSM in Lima, Peru with symptomatic or asymptomatic GC and/or CT infection between 2012 and 2014. We enrolled 44 MSM with symptomatic urethritis/proctitis and 129 MSM with asymptomatic GC/CT infection, diagnosed based on nucleic acid testing (Aptima Combo 2 Transcription-Mediated Amplification [TMA]) from urethral, pharyngeal, and rectal sites. Eligible participants were randomly assigned to receive either standard PN counseling (n = 84) or counseling plus EPT (cefixime 400 mg/azithromycin 1 g) for up to five recent partners (n = 89). Self-reported notification was assessed by computer-assisted self-administered survey among 155 participants who returned for 14-day follow-up. RESULTS: The median age of participants was 26 (interquartile range [IQR]: 23-31) with a median of 3 sexual partners (IQR: 2-4) in the previous 30-day period. Among all participants, 111/155 (71.6%) notified at least one partner at 14-day follow-up with a median of 1 partner notified per participant (IQR: 0-2). For participants randomized to receive EPT, 69/83 (83.1%) reported notifying at least one partner, compared with 42/72 (58.3%) of participants in the control arm (odds ratio = 3.52; 95% confidence interval [CI]: 1.68-7.39). The proportion of all recent partners notified was significantly greater in the EPT than in the control arm (53.5%, 95% CI: 45.0-62.0% versus 36.4%, 95% CI: 27.0-47.4%). CONCLUSIONS: Provision of EPT led to significant increases in notification among Peruvian MSM diagnosed with GC/CT infection. Additional research is needed to assess the impact of EPT on biological outcomes, including persistent or recurrent infection, antimicrobial resistance, and HIV/STI transmission, in MSM sexual networks.

RESUMEN

Men who have sex with men (MSM) and transgender women (TW) are key populations in the HIV epidemic. HIV status communication between sex partners can inform decisions regarding sexual behavior. MSM and TW were asked about HIV status communication with sex partners at baseline, 9- and 18-months. GEE models assessed associations with HIV status communication at baseline using prevalence ratios (PRs) and longitudinally using odds ratios (ORs). At baseline, those who had previously had an HIV test, disclosed their HIV status to 42 % of their sex partners. HIV status communication was associated with knowing their sex partner's HIV status at baseline (aPR 5.20) and longitudinally (aOR 1.86). HIV positivity at baseline was negatively associated with HIV status communication during follow-up (aOR 0.55). All reported aPRs and aORs have p < 0.05. Interventions promoting HIV status communication and more frequent HIV testing should be explored as current efforts are insufficient.

RESUMEN

Violence experience can increase HIV risk behaviors; however, literature is scarce on violence among male sex workers (MSWs) globally. In 2014, 210 Peruvian MSWs (median age 24.9) were interviewed about their experience of physical, emotional, and sexual violence and condom use with non-paying intimate partners and clients and were tested for HIV. Multivariable models examined relationships between violence in the past 6 months, condomless anal intercourse (CLAI) in the past 3 months and HIV infection. HIV infection (24 %), CLAI (43 %), being a violence victim (42 %) and perpetrator (39 %) were common. In separate multivariable models, being a violence victim [adjusted prevalence ratio aPR = 1.49 (95 % CI 1.09-2.03)] and perpetrator [aPR = 1.39 (1.03-1.87)] were associated with CLAI. Further, being a victim [aPR = 1.65 (1.04-2.62)] was associated with HIV infection. Violence, which was significantly associated with CLAI and HIV infection, is common among Peruvian MSWs, reinforcing the importance of violence awareness and prevention as HIV risk-reduction strategies.

RESUMEN

INTRODUCTION: There are few published articles describing the epidemiology of facial fractures in South Africa, and there is only one published study in pediatric patients. MATERIAL AND METHODS: This study retrospectively reviewed all medical records in a major metropolitan pediatric hospital in Cape Town, South Africa from September 2006 through May 2014. Inclusion criteria were children aged under the age of 13 with facial fractures. Fractures were assessed through head computed tomography (CT) scans. Patient's age, sex, cause of injury, general condition, existence of concomitant injuries, location of fractures, type of interventions, and length of stay were recorded and analyzed. RESULTS: A total of 53 men and 34 women were included in the study. Motor vehicle collisions (MVC) were the most common cause of facial fractures (56.3%). One hundred thirty facial fractures were presented on CT scans. The most common fractures in this study were mandible (43.1%). Comparing unrestrained motor vehicle collisions (UMVC) patients with those of other etiologies (OE), there was an increase in the average number of fractures (OE: 1.1, UMVC: 1.9; P < 0.0001), the average length of stay (OE: 4 days, UMVC: 9 days; P < 0.003), and the probabilities of sustaining concomitant injuries (OE: 31.0%, UMVC: 68.8%; P < 0.05) and requiring an operation (OE: 42.3%, UMVC: 81.3%; P < 0.01). DISCUSSION: This study establishes MVC as the most common etiology of facial fractures in South Africa. It demonstrates an increase in the complexity of facial injuries in unrestrained MVCs, suggesting the need for public awareness campaigns to install restraint devices in automobiles in South Africa.

RESUMEN

BACKGROUND: Increased HIV testing frequency among high-risk populations such as men who have sex with men (MSM) and male-to-female transgender women (TW) can lead to earlier treatment and potentially reduce HIV transmission. METHODS: We analyzed baseline survey data from 718 high-risk, young (median age 29 [interquartile range 23-35]) MSM/TW enrolled in a community-based HIV prevention trial between 2008-2009. Participants were recruited from 24 neighborhoods in and around Lima, Peru. We assessed HIV testing frequency, testing behaviour, and motivations and barriers to testing. Multivariate analysis identified correlates to prior HIV testing. RESULTS: Overall, 79.6% reported HIV testing within their lifetimes, however, only 6.2% reported an average of two tests per year, as per Peruvian Ministry of Health guidelines. The most commonly reported motivators for testing were to check one's health (23.3%), lack of condom use (19.7%), and availability of free testing (14.0%), while low self-perceived risk for HIV (46.9%), fear of a positive result (42.0%), and lack of access to testing services (35.7%) were the most frequently reported barriers. In multivariate analysis, factors independently associated with HIV testing included age [adjusted prevalence ratio (APR) 1.00, 95% CI (1.00-1.01)], transgender-identification vs. gay-identification [APR 1.11, 95% CI (1.03-1.20)], history of transactional sex [APR 1.16, 95% CI (1.07-1.27)], and prior sexually transmitted infection diagnosis [APR 1.15, 95% CI (1.07-1.24)]. CONCLUSIONS: An overwhelming majority of participants did not meet the standard-of-care for testing frequency. The reported motivations and barriers to testing highlight issues of risk perception and accessibility. Our findings suggest utilizing non-traditional outreach methods and promoting HIV testing as a routine part of healthcare in Peru to encourage testing and knowledge of HIV serostatus.

RESUMEN

OBJECTIVES: To describe the sociodemographic and sex work characteristics, recent sexual practices, HIV risk perception and testing history, and HIV and syphilis prevalence of Cercado (downtown) and non-Cercado (close urban) male sex workers (MSWs) in Lima, Peru. METHODS: Eighty-nine MSWs completed a self-administered survey and participated in HIV and syphilis testing. RESULTS: Cercado MSWs had significantly lower median weekly earnings than non-Cercado MSWs (US$43 vs US$72, p=0.04). Most non-Cercado MSWs (81%) reported only insertive anal intercourse with male/transgender partners, while Cercado MSWs primarily reported only insertive (52%) or insertive and receptive (45%) anal intercourse (p=0.03). Consistent condom use was low with insertive and receptive anal intercourse in both subgroups. Among MSWs with recent female partners, condom use with the last partner was lower among Cercado versus non-Cercado MSWs for vaginal sex (37% vs 65%, p=0.04) and anal sex (27% vs 80%, p=0.01). More Cercado than non-Cercado MSWs (57% vs 42%) perceived high HIV risk (p=0.05) and Cercado MSWs had a much higher prevalence than non-Cercado MSWs of HIV (23% vs 4%, p=0.04) and syphilis (22% vs 0%, p=0.02) infections. CONCLUSIONS: MSWs in Lima are diverse and Cercado MSWs are 'just getting by,' engaging in more risk behaviours, and more likely to have HIV/STIs. Future research should identify, describe and carry out HIV/STI testing with broader groups of MSWs and their client and non-client partners. Prevention efforts should provide HIV/STI risk reduction education for MSWs and related subgroups who are currently not targeted such as female partners.

RESUMEN

BACKGROUND: Alcohol use has a detrimental impact on the HIV epidemic, especially in sub-Saharan Africa. HIV counseling and testing (HCT) may provide a contact opportunity to intervene with hazardous alcohol use; however, little is known about how alcohol consumption changes following HCT. METHODS: We utilized data from 2056 participants of a randomized controlled trial comparing two methods of HCT and subsequent linkage to HIV care conducted at Mulago Hospital in Kampala, Uganda. Those who had not previously tested positive for HIV and whose last HIV test was at least one year in the past were eligible. Participants were asked at baseline when they last consumed alcohol, and prior three month alcohol consumption was measured using the Alcohol Use Disorders Identification Test - Consumption (AUDIT-C) at baseline and quarterly for one year. Hazardous alcohol consumption was defined as scoring ≥3 or ≥4 for women and men, respectively. We examined correlates of alcohol use at baseline, and of hazardous and non-hazardous drinking during the year of follow-up using multinomial logistic regression, clustered at the participant level to account for repeated measurements. RESULTS: Prior to HCT, 30% were current drinkers (prior three months), 27% were past drinkers (>3 months ago), and 44% were lifetime abstainers. One-third (35%) of the current drinkers met criteria for hazardous drinking. Hazardous and non-hazardous self-reported alcohol consumption declined after HCT, with 16% of baseline current drinkers reporting hazardous alcohol use 3 months after HCT. Independent predictors (p < 0.05) of continuing non-hazardous and hazardous alcohol consumption after HCT were sex (male), alcohol consumption prior to HCT (hazardous), and HIV status (negative). Among those with HIV, non-hazardous drinking was less likely among those taking antiretroviral therapy (ART). CONCLUSIONS: HCT may be an opportune time to intervene with alcohol consumption. Those with HIV experienced greater declines in alcohol consumption after HCT, and non-hazardous drinking decreased for those with HIV initiating ART. HCT and ART initiation may be ideal times to intervene with alcohol consumption. Screening and brief intervention (SBI) to reduce alcohol consumption should be considered for HCT and HIV treatment venues.

RESUMEN

OBJECTIVE: To compare pregnancy outcomes using self-reported and objective levels of intracellular tenofovir diphosphate (TFV-DP) in pregnant women using preexposure prophylaxis (PrEP). DESIGN: We enrolled pregnant women >15 years without HIV at first antenatal care visit in an observational cohort study to compare pregnancy outcomes by PrEP use. METHODS: Exposure defined as: any PrEP use [tenofovir disoproxil and emtricitabine (TDF/FTC]) prescription + reported taking PrEP], or objectively-measured TFV-DP in dried blood spots in PrEP-using pregnant women. The primary outcome was a composite of pregnancy loss, preterm birth (<37weeks), low birthweight (<2500 g), small for gestational age ([SGA] ≤ tenth percentile), or neonatal death. Multivariable logistic regression models evaluated individual and composite adverse outcomes by self-reported or objectively measured PrEP use adjusting for age, gestational age, gravidity and socio-economic status. RESULTS: Between August 19 and February 23, we followed 1195 pregnant women and ascertained 1145 pregnancy outcomes (96%); 72% ( n  = 826) reported taking PrEP while pregnant, 16% did not take PrEP ( n  = 178), 12% were unconfirmed ( n  = 141). Overall, 94.5% ( n  = 1082) had singleton live births with a median birthweight of 3.2 kg [interquartile range (IQR) = 2.9-3.5], with no difference in pregnancy loss between self-reported PrEP exposed vs. unexposed [4.0 vs. 5.6%; adjusted odds ratio (aOR) = 0.65, 95% confidence interval (CI) = 0.32-1.47]. Composite adverse outcomes did not differ by reported PrEP use (20% for both groups; aOR = 1.07, 95% CI = 0.71-1.63). Comparing objective PrEP use (any TFV-DP vs. no TFV-DP or not on PrEP), adverse outcomes did not differ (aOR = 0.64, 95% CI = 0.39-1.04), nor did other outcomes including preterm birth nor SGA. CONCLUSIONS: Pregnancy outcomes did not differ by PrEP exposure (self-reported or objective), suggesting real-world efficacy that TDF/FTC as PrEP is safe in pregnancy.
