Awareness, acceptability, and intention to initiate HIV pre-exposure prophylaxis among pregnant women

Knowledge and attitude to HIV pre exposure prophylaxis among women in five sub-Saharan African countries: a multilevel model analysis of population-based survey 2021-2022

BACKGROUND

HIV Pre-Exposure Prophylaxis (HIV PrEP) may help reduce the rate of HIV infection among women in sub-Saharan Africa (SSA). This study aimed to assess women's knowledge and attitudes toward PrEP, a crucial component of HIV prevention, using nationwide data. It is the first study of its kind conducted in five SSA countries: Burkina Faso, Ghana, Côte d'Ivoire, Kenya, and Tanzania. The primary objective was to examine women's knowledge and attitudes toward PrEP for the prevention of HIV infection, as well as to explore individual- and community-level factors associated with it.

METHODS

The current study utilized the 2021/22 demographic and health survey datasets from five African nations, namely Burkina Faso, Côte d'Ivoire, Ghana, Kenya, and Tanzania. The analysis was performed using Stata 17. A weighted sample of 77,052 women of reproductive age participated in the survey. Univariate and multivariable multilevel logistic regressions were conducted to assess parameters related to knowledge and attitudes toward PrEP in these countries. In both the univariate regression and the final model, the significance of variables was determined using P values of ≤ 0.2 and < 0.05.

RESULTS

Overall, only about 13.88 (95% CI: 13.64,14.12) of women had knowledge and attitudes toward HIV PrEP. The highest (34.29%) and lowest (5.61%) values were observed for Kenya and Tanzania respectively. Higher rates of knowledge, and attitude toward HIV PrEP among women were independently associated with age 25-34 years old (AOR = 1.52, 95% CI:1.41,1.64), and 35-49 years old (AOR = 1.56, 95% CI:1.43,1.69), primary education level (AOR = 1.79,95% CI:1.65,1.95), and secondary/higher education level (AOR = 2.92, 95% CI: 2.67,3.20), richer (AOR = 1.14, 95% CI:1.02,1.27), and richest (AOR = 1.21, 95% CI:1.06,1.37), employed women (AOR = 1.82, 95% CI:1.65,1.99), had media exposure (AOR = 1.49,95% CI:1.40,1.59),knowledge of modern contraception (AOR = 2.62, 95% CI: 1.94,3.43), had at least one ANC visit (AOR = 1.99, 95% CI:1.47,2.69), gave birth at health institutions (AOR = 1.17, 95% CI: 1.02,1.37), ever had given birth (AOR = 1.53, 95% CI: 1.41,1.66), female household heads (AOR = 1.24, 95% CI:1.17,1.31), rural women (AOR = 0.83, 95% CI: 0.76,0.89). Similarly, women from communities with high ANC coverage (AOR = 1.84, 95% CI: 1.61,2.11), high community mass media exposure (AOR = 1.62, 95% CI: 1.39,1.88), and high community wealth level (AOR = 1.48, 95% CI: 1.30,1.68), and women from the high illiteracy rate community (AOR = 0.71, 95% CI: 0.61,0.82) showed statistically significant associations with the outcome variable in the final model.

CONCLUSIONS

Less than one-seventh of women exhibited knowledge of and positive attitudes toward HIV PrEP. All stakeholders involved in HIV/AIDS prevention and control have recognized the significance of the factors mentioned above. Enhancing maternal health services, such as promoting institutional delivery, contraception, antenatal care (ANC), and women's empowerment, alongside harnessing the power of media and embracing these transformative changes, will contribute to a greater understanding of and more favorable attitudes toward HIV PrEP within the population.

Infant feeding: emerging concepts to prevent HIV transmission

PURPOSE OF REVIEW

HIV screening in pregnancy, universal suppressive antiretroviral therapy (ART) and breastfeeding avoidance can almost completely prevent vertical transmission of HIV. Breastfeeding is associated with an additional risk of transmission, although this risk is extremely low with suppressive maternal ART. This minimal risk must be balanced with the benefits of breastfeeding for women living with HIV (WLHIV) and their infants. Guidance in high-income countries has evolved, moving towards supported breast feeding for women on suppressive ART.

RECENT FINDINGS

Breastmilk transmission accounts for an increasing proportion of new infant infections globally. The majority of transmission data comes from studies including women not on suppressive ART. Breastmilk transmissions in the context of undetectable viral load have rarely occurred, although risk factors remain unclear. Outcome data on supported breastfeeding are accumulating, providing evidence for guidelines and informing infant feeding decisions. Long-acting ART for maternal preexposure prophylaxis or treatment, and infant postnatal prophylaxis are promising future options.

SUMMARY

Breastfeeding on suppressive ART has a very low risk of vertical transmission and can have multiple benefits for WLHIV and their infants. However, caution is advised with relaxation of breastfeeding guidance so as not to jeopardise the global goal of elimination of vertical transmission by 2030.

Age-related factors associated with intention to initiate pre-exposure prophylaxis among cisgender women in Washington D.C

Background

Pre-exposure prophylaxis (PrEP) utilization among cisgender women (subsequently 'women') is low across age groups, relative to their risk of HIV acquisition. We hypothesize that age-related differences in psychosocial factors also influence women's intention to initiate oral PrEP in Washington, D.C.

Methods

A secondary analysis of a cross-sectional survey data was performed to evaluate factors influencing intention to initiate oral PrEP among women seen at a family planning and a sexual health clinic. A bivariate analysis was performed to identify differences by age group in demographic characteristics, indications for PrEP, and attitudes toward PrEP; we then performed additional bivariate analysis to assess these variables in relation to PrEP intention.

Results

Across age groups, perceived risk of HIV acquisition was not significantly different and was not associated with intention to initiate PrEP. Awareness of and attitude toward PrEP, injunctive norms, descriptive norms, and self-efficacy were not different across age, however there were significant age-associated differences in relation to PrEP intention. Specifically, among 18-24-year-olds, intention to start PrEP was associated with support from provider (p = 0.03), main sexual partner (p < 0.01), and peers (p < 0.01). For women 25-34 years old, having multiple sexual partners (p = 0.03) and support from casual sexual partners (p = 0.03) was also important. Among women 35-44 years old, prior awareness of PrEP (p = 0.02) and their children's support of PrEP uptake (p < 0.01) were associated with intention to initiate PrEP. Among 45-55 year-old women intention to initiate PrEP was positively associated with engaging in casual sex (p = 0.03) and negatively associated with stigma (p < 0.01).

Conclusion

Overall, there were more similarities than differences in factors influencing intention to initiate PrEP across age groups. Observed differences offer an opportunity to tailor PrEP delivery and HIV prevention interventions to increase awareness and uptake for cisgender women.

Understanding Psychosocial Determinants of PrEP Uptake Among Cisgender Women Experiencing Heightened HIV Risk: Implications for Multi-Level Communication Intervention

Pre-exposure prophylaxis (PrEP) is a highly effective daily pill that decreases the likelihood of HIV acquisition by up to 92% among individuals at risk for HIV. PrEP can be discretely used, autonomously controlled, and in place at the time of risk exposure, making it an especially promising method for HIV prevention for cisgender women (CGW). But, PrEP is underutilized by CGW relative to the demonstrable need. We apply the Integrative Model of Behavioral Prediction to identify the critical psychosocial factors that shape CGW's intentions to use PrEP and their relevant underlying beliefs. We surveyed (N = 294) community- and clinic-recruited PrEP eligible CGW to understand the relative importance of attitudes, norms, and efficacy in shaping PrEP intentions. We utilized structural equation modeling to identify the relevant paths. We inspected the summary statistics in relation to three message three selection criteria. We identified beliefs that demonstrated (1) an association with intention, (2) substantial room to move the population, (3) practicality as a target for change through communication intervention. Results show that PrEP awareness was low. When women learned about PrEP, they voiced positive intentions to use it. There were significant and positive direct effects of SE (0.316***), attitudes (0.201**), and subjective norms (0.249***) on intention to initiate PrEP. We illustrate the strategic identification of beliefs within the relevant paths using the 3 belief selection criteria. We also discuss implications for social and structural communication interventions to support women's HIV prevention.

Uptake of and intention to use oral pre-exposure prophylaxis for HIV among pregnant and post-natal women in Eswatini: a cross-sectional survey

Introduction

In Eswatini, HIV incidence among women of childbearing age is 1.45%. Eswatini introduced oral pre-exposure prophylaxis (PrEP) for HIV prevention in 2016 and requires that all HIV-negative pregnant and post-natal women (PPW) visiting health care facilities be offered PrEP.

Methods

Between September-November 2021, we conducted a survey among HIV-negative PPW from 16 purposively selected healthcare facilities in the Hhohho and Shiselweni regions in Eswatini. We interviewed consenting HIV-negative PPW using a structured questionnaire to collect data on PrEP knowledge, attitudes, intentions, and practices, as well as information on partner HIV status and stigma. Multivariate logistic regression was used to determine predictors of PrEP use and intention, adjusted for significant covariates.

Results

Of 1,484 PPW women approached, 1,149 consented and were interviewed, of whom 704 (61.3%) were post-partum and 445 (38.7%) pregnant. The median age was 25 years [Interquartile Range (IQR) = 21-30 years], with 533 (46.4%) 18-24 years old. Among the 1,149 women, 930 (80.7%) had ever heard about PrEP; 635 (55.3%) had knowledge about PrEP; 183 (15.9%) were currently using PrEP; and 285 (24.8%) had ever used PrEP. Increased odds of PrEP use were associated having HIV-positive male partner (aOR:7.76, 95%CI 3.53- 17.04); positive attitudes to PrEP (aOR:1.56, 95%CI: 1.02-2.40); and high self-efficacy (aOR:1.49, 95%CI:1.13-1.98). Among 864 women who never used PrEP, 569 (65.3%) intended to use PrEP in the future. Odds of intention to use PrEP were higher among women with low levels of education (aOR:2.23, 95% CI: 1.32-3.77); who ever heard about PrEP (aOR:1.69, 95%CI: 1.12-2.56); and had high self-efficacy (aOR:1.57, 95%CI: 1.31-1.87). Regarding stigma, among all women, 759 (66%) either agreed or strongly agreed that people would think they have HIV if they were to use PrEP; 658 (57.3%) reported they would be labelled as having multiple sex partners; 468 (40.7%) reported that their partner would think they are having risky sex with other people. Of 102 women who had discontinued PrEP, a majority stopped due to side effects 32 (35.2%).

Conclusion

Only about 50% of women had knowledge of PrEP, and PrEP uptake among PPW was low, though intention to use appeared high. More efforts to reduce stigma and promote PrEP use, including adequate information on side effects, are needed.

Implementation of an Educational Intervention to Improve HIV Pre-Exposure Prophylaxis Services for Women in an Urban Sexual Health Clinic

To test the hypothesis that implementation of a multicomponent, educational HIV pre-exposure prophylaxis (PrEP) intervention to promote universal PrEP services for cisgender women (subsequently "women") in sexual and reproductive health centers would improve the proportion of women screened, offered, and prescribed PrEP, we implemented a multicomponent, educational intervention in a Washington D.C. Department of Health-sponsored sexual health clinic. The clinic serves a patient population with high-potential exposure to HIV. The intervention included clinic-wide PrEP trainings, an electronic health record prompt for PrEP counseling by providers, and educational videos in the waiting room. We collected preimplementation data from March 22, 2018 to July 4, 2018, including 331 clinical encounters for 329 women. Between July 5, 2018 and July 1, 2019, there were 1733 clinical encounters for 1720 HIV-negative women. We used mixed methods to systematically assess intervention implementation using the Reach Effectiveness Adoption Implementation Maintenance framework. Additionally, we assessed the interventions' acceptability and feasibility among providers through semistructured interviews. The proportion of women screened by providers for PrEP (5.6% preimplementation to a mean of 89.2% of women during the implementation period, p < 0.01), offered (6.2 to 69.8%, p < 0.01), and prescribed PrEP (2.6 to 8.1%, p < 0.01) by providers increased significantly in the implementation period. Providers and clinic staff found the intervention both highly feasible and acceptable and demonstrated increased knowledge of PrEP and HIV prevention associated with the clinic-wide trainings. Our results demonstrate the effectiveness of a low-cost educational intervention to increase provision of integrated PrEP services in an urban sexual health clinic serving women with high-potential exposure to HIV.
