Factors associated with declining HIV testing and failure to return for results among pregnant women in Vietnam

A systematic review of barriers and facilitators to antenatal screening for HIV, syphilis or hepatitis B in Asia: Perspectives of pregnant women, their relatives and health care providers

BACKGROUND

Despite improvements, the prevalence of HIV, syphilis, and hepatitis B remains high in Asia. These sexually transmitted infections (STIs) can be transmitted from infected mothers to their children. Antenatal screening and treatment are effective interventions to prevent mother-to-child transmission (MTCT), but coverage of antenatal screening remains low. Understanding factors influencing antenatal screening is essential to increase its uptake and design effective interventions. This systematic literature review aims to investigate barriers and facilitators to antenatal screening for HIV, syphilis, and hepatitis B in Asia.

METHODS

We conducted a systematic review by searching Ovid (MEDLINE, Embase, PsycINFO), Scopus, Global Index Medicus and Web of Science for published articles between January 2000 and June 2023, and screening abstracts and full articles. Eligible studies include peer-reviewed journal articles of quantitative, qualitative and mixed-method studies that explored factors influencing the use of antenatal screening for HIV, syphilis or hepatitis B in Asia. We extracted key information including study characteristics, sample, aim, identified barriers and facilitators to screening. We conducted a narrative synthesis to summarise the findings and presented barriers and facilitators following Andersen's conceptual model.

RESULTS

The literature search revealed 23 articles suitable for inclusion, 19 used quantitative methods, 3 qualitative and one mixed method. We found only three studies on syphilis screening and one on hepatitis B. The analysis demonstrates that antenatal screening for HIV in Asia is influenced by many barriers and facilitators including (1) predisposing characteristics of pregnant women (age, education level, knowledge) (2) enabling factors (wealth, place of residence, husband support, health facilities characteristics, health workers support and training) (3) need factors of pregnant women (risk perception, perceived benefits of screening).

CONCLUSION

Knowledge of identified barriers to antenatal screening may support implementation of appropriate interventions to prevent MTCT and help countries achieve Sustainable Development Goals' targets for HIV and STIs.

Factors affecting antenatal screening for HIV in Nepal: results from Nepal Demographic and Health Surveys 2016 and 2022

OBJECTIVES

Antenatal screening for HIV remains low in Nepal. Identifying factors associated with the uptake of antenatal screening is essential to increase uptake and prevent mother-to-child transmission (MTCT). This study investigated the effects of individual-level and district-level characteristics on the utilisation of antenatal screening for HIV in Nepal and how these effects changed between 2016 and 2022.

DESIGN

We used publicly available cross-sectional data from 2016 to 2022 Nepal Demographic and Health Surveys.

SETTING

Stratified, multistage, random sampling was used to collect nationally representative data.

PARTICIPANTS

1978 and 2007 women aged 15-49 years who gave birth in the 2 years preceding the surveys.

PRIMARY AND SECONDARY OUTCOME MEASURES

We used multilevel models to estimate associations between antenatal screening and potential factors influencing it in 2016 and 2022. We used districts as a random effect and looked at the intraclass correlation coefficients to disentangle the geographical effects. To distinguish barriers to HIV screening from barriers to accessing antenatal care (ANC) services, we performed similar analyses with whether the woman attended at least one ANC visit as the dependent variable.

RESULTS

Factors associated with antenatal screening have not changed significantly between 2016 and 2022. Higher uptake of HIV screening was found among women with higher education, the pregnancy being desired later and women who had four or more ANC visits. Being from a poorer family and having low knowledge of MTCT and the medicines to prevent transmission were associated with lower uptake. From the supply side, no factors had a significant effect on antenatal screening. Factors associated with antenatal screening and those associated with any ANC were different. Our results also showed a partial importance of geographical factors on screening uptake.

CONCLUSIONS

Our results supported that antenatal screening could be improved by enhancing access to information and improving the availability of free screening.

Socioeconomic Inequalities in the HIV Testing during Antenatal Care in Vietnamese Women

Although HIV (human immunodeficiency virus) testing for all women has been promoted by Vietnam's Ministry of Health since 2000, test acceptance rates in this country were reported to be less than 30% in the community. This country has been facing the barriers to approach the national services towards transmission prevention from mother to child including HIV testing during antenatal care (ANC) towards mothers. Here, we aim to assess the socioeconomic inequalities in HIV testing during ANC among Vietnamese women. This study used available data from the Vietnam Multiple Indicator Cluster Survey 2014. Overall, the prevalence of HIV testing during antenatal care was 30% and the concentrate index (CCI) was 0.1926. There was significant inequality between women classified as poor and rich, and when stratified by social characteristics, inequality was found in women aged 15-49 years (CCI: 0.4), living in rural areas (CCI: 0.3), belonging to ethnic minorities (CCI: 0.5) and having primary or less education (CCI: 0.4). In the multivariate logistic regression analysis, ethnicity and socioeconomic status were significant factors associated with HIV testing during ANC. We found the prevalence of HIV testing during ANC was low, and its inequalities were associated with age, living area, ethnicity, education, and economic status.

Determinants of HIV provider-initiated testing and counseling screening service used by pregnant women in primary health centers in Surabaya

Background: Offering free HIV screening service for pregnant women in primary health center in Surabaya has become obligatory since 2014, but only 70% used the service. Prior studies on HIV screening mostly focused on Voluntary Counseling and Testing.Methods: This was a cross-sectional study. Interviews were conducted with 150 pregnant women attending antenatal care in 1 of 9 public health centers (PHCs) in Surabaya and offered HIV screening within the same PHC. The eligibility criterium was pregnant women attending antenatal care in PHCs. The exclusion criteria were having been counseled for HIV prior to the interviews and/or experiencing an obstetric emergency. Using PRECEDE Framework with the concept of a comprehensive framework, this study focuses on identifying determinants of HIV PITC service use in PHCs in Surabaya. Binary logistic regressions and multiple binary logistic regressions were used in analyses.Results: The service use was associated with self-confidence of getting blood drawn for the test (p<0.001, adjusted OR=12.368, 95% CI=3.237–47.250) and past use of midwife private service for current pregnancy (p=0.029, adjusted OR=3.902, 95% CI=1.150–13.246). Self-confidence of getting blood drawn for HIV test mediated the effect of past use of midwife’s private service on HIV screening use.Conclusion: Past use of midwife’s private service affected self-confidence of getting blood drawn for HIV test on HIV screening use, and self-confidence affected the use of HIV PITC. This study results suggest that more midwives’ private practices are needed to increase the use of HIV PITC screening in PHC.

Utilization of HIV testing services among pregnant mothers in low income primary care settings in northern Ethiopia: a cross sectional study

Background

HIV testing of women in child bearing age is an entry point for preventing mother-to-child transmission of HIV (MTCT). This study aims to identify the proportion of women tested for HIV and to determine factors associated with utilization of HIV testing services among pregnant mothers in primary care settings in northern Ethiopia.

Methods

A cross sectional study was conducted in 416 pregnant women from four primary care centers between October 2, 2012 and May 31, 2013 in East Gojjam, Ethiopia.

Results

The proportion of mothers who tested for HIV was 277(67%). Among mothers who were not tested for HIV, lack of HIV risk perception (n = 68, 49%) was a major self-reported barrier for HIV testing. A multivariable logistic regression analysis showed that those pregnant women who had comprehensive knowledge about MTCT had an Adjusted Odd Ratio (AOR) of 3.73 (95% CI: 1.56, 8.94), having comprehensive knowledge on prevention of mother to child transmission (PMTCT) of HIV an AOR of 2.56 (95% CI: 1.26, 5.19), and a favorable attitude towards persons living with HIV an AOR of 2.42 (95%CI, 1.20, 4.86) were more likely to be tested for HIV.

Conclusion

One third of pregnant women had never been tested for HIV until the time of the study. Efforts should be made to improve mother’s knowledge about MTCT and PMTCT to increase uptake of HIV testing. Enhancing mother’s HIV risk perception to scale up HIV testing in resource limited setting is highly recommended.

Returning for HIV Test Results: A Systematic Review of Barriers and Facilitators

This systematic review aims to identify factors that facilitate or hinder the return for HIV test results. Four electronic databases were searched. Two independent reviewers selected eligible publications based on inclusion/exclusion criteria. Quantitative studies published since 1985 were included. Thirty-six studies were included in the final review. Individual level barriers included sociodemographic characteristics, such as being a male, of young age and low education level, risk behaviours such as injecting drugs, having multiple sexual partners, and psychosocial factors. Older age, higher education level, being a woman, having high self-esteem, having coping skills, and holding insurance coverage were identified as facilitators. Interpersonal barriers and facilitators were linked to risk behaviours of sexual partners. Contextual barriers included essentially the HIV testing center and its characteristics. This review identified the most important factors that need to be addressed to ensure that people return for their HIV test results.

Lower Levels of Antiretroviral Therapy Enrollment Among Men with HIV Compared with Women - 12 Countries, 2002-2013

Equitable access to antiretroviral therapy (ART) for men and women with human immunodeficiency virus (HIV) infection is a principle endorsed by most countries and funding bodies, including the U.S. President's Emergency Plan for AIDS (acquired immunodeficiency syndrome) Relief (PEPFAR) (1). To evaluate gender equity in ART access among adults (defined for this report as persons aged ≥15 years), 765,087 adult ART patient medical records from 12 countries in five geographic regions* were analyzed to estimate the ratio of women to men among new ART enrollees for each calendar year during 2002-2013. This annual ratio was compared with estimates from the Joint United Nations Programme on HIV/AIDS (UNAIDS)(†) of the ratio of HIV-infected adult women to men in the general population. In all 10 African countries and Haiti, the most recent estimates of the ratio of adult women to men among new ART enrollees significantly exceeded the UNAIDS estimates for the female-to-male ratio among HIV-infected adults by 23%-83%. In six African countries and Haiti, the ratio of women to men among new adult ART enrollees increased more sharply over time than the estimated UNAIDS female-to-male ratio among adults with HIV in the general population. Increased ART coverage among men is needed to decrease their morbidity and mortality and to reduce HIV incidence among their sexual partners. Reaching more men with HIV testing and linkage-to-care services and adoption of test-and-treat ART eligibility guidelines (i.e., regular testing of adults, and offering treatment to all infected persons with ART, regardless of CD4 cell test results) could reduce gender inequity in ART coverage.

Short communication: phylogenetic characterization of HIV type 1 CRF01_AE V3 envelope sequences in pregnant women in Northern Vietnam

Characterization of HIV-1 strains is important for surveillance of the HIV-1 epidemic. In Vietnam HIV-1-infected pregnant women often fail to receive the care they are entitled to. Here, we analyzed phylogenetically HIV-1 env sequences from 37 HIV-1-infected pregnant women from Ha Noi (n=22) and Hai Phong (n=15), where they delivered in 2005-2007. All carried CRF01_AE in the gp120 V3 region. In 21 women CRF01_AE was also found in the reverse transcriptase gene. We compared their env gp120 V3 sequences phylogenetically in a maximum likelihood tree to those of 198 other CRF01_AE sequences in Vietnam and 229 from neighboring countries, predominantly Thailand, from the HIV-1 database. Altogether 464 sequences were analyzed. All but one of the maternal sequences colocalized with sequences from northern Vietnam. The maternal sequences had evolved the least when compared to sequences collected in Ha Noi in 2002, as shown by analysis of synonymous and nonsynonymous changes, than to other Vietnamese sequences collected earlier and/or elsewhere. Since the HIV-1 epidemic in women in Vietnam may still be underestimated, characterization of HIV-1 in pregnant women is important to observe how HIV-1 has evolved and follow its molecular epidemiology.

HIV-1 mother-to-child transmission, post-test counselling, and antiretroviral prophylaxis in Northern Viet Nam: a prospective observational study

BACKGROUND

Pregnant women fear being identified as HIV-1-infected and this has hampered prevention programmes and the calculation of transmission rates in Viet Nam. We introduced post-test counselling, antiretroviral prophylaxis, and formula feeding, and determined the vertical transmission rate in parts of Northern Viet Nam.

METHODS

HIV infection was identified in 234 pregnant women; 182 (77.8%) accepted follow-up of their children. Counselling was given on 3-7 occasions for altogether approximately 6 h on antiretroviral prophylaxis and formula feeding to avoid transmission, and on the importance of surveillance of the child. All children were formula-fed. A polymerase chain reaction (PCR) was used for the diagnosis of HIV-1 in the children. One hundred and thirty-five of the 182 mothers allowed ≥ 3 blood samples to be taken from birth to ≥ 1 y of age, 32/182 provided a birth sample only, and 15/182 provided a sample later only. Nevirapine was given at delivery to 93/135 (69%) women, and to 128/135 (95%) children. Additionally, combination therapy was given to 15/135 (11%) who entered the study before delivery, and azidothymidine to their children for 1 week.

RESULTS

Nine of 135 (6.7%) children became infected and 2/15 of the others, giving altogether 11/150 infected (7.3%). Intrauterine transmission was identified in 7/167 (4.2%) children by a positive PCR test at birth. PCR was negative at birth but positive at 1 month in 2/135 (1.5%), pointing to delivery-associated transmission. Thus, intrauterine transmission accounted for 78% (7/9). None of the uninfected children died, but 3/11 (p =0.004) of the HIV-1-infected died (in AIDS).

CONCLUSION

Post-test confidential counselling, formula feeding, and antiretroviral prophylaxis resulted in low rates of delivery-associated and late HIV-1 transmissions.

Number and timing of antenatal HIV testing: evidence from a community-based study in Northern Vietnam

BACKGROUND

HIV testing for pregnant women is an important component for the success of prevention of mother-to-child transmission of HIV (PMTCT). A lack of antenatal HIV testing results in loss of benefits for HIV-infected mothers and their children. However, the provision of unnecessary repeat tests at a very late stage of pregnancy will reduce the beneficial effects of PMTCT and impose unnecessary costs for the individual woman as well as the health system. This study aims to assess the number and timing of antenatal HIV testing in a low-income setting where PMTCT programmes have been scaled up to reach first level health facilities.

METHODS

A cross-sectional community-based study was conducted among 1108 recently delivered mothers through face-to-face interviews following a structured questionnaire that focused on socio-economic characteristics, experiences of antenatal care and HIV testing.

RESULTS

The prevalence of women who lacked HIV testing among the study group was 10% while more than half of the women tested had had more than two tests during pregnancy. The following factors were associated with the lack of antenatal HIV test: having two children (aOR 2.1, 95% CI 1.3-3.4), living in a remote rural area (aOR 7.8, 95% CI 3.4-17.8), late antenatal care attendance (aOR 3.6, 95% CI 1.3-10.1) and not being informed about PMTCT at their first antenatal care visits (aOR 7.4, 95% CI 2.6-21.1). Among women who had multiple tests, 80% had the second test after 36 weeks of gestation. Women who had first ANC and first HIV testing at health facilities at primary level were more likely to be tested multiple times (OR 2.9 95% CI 1.9-4.3 and OR = 4.7 95% CI 3.5-6.4), respectively.

CONCLUSIONS

Not having an HIV test during pregnancy was associated with poor socio-economic characteristics among the women and with not receiving information about PMTCT at the first ANC visit. Multiple testing during pregnancy prevailed; the second tests were often provided at a late stage of gestation.

Early uptake of HIV counseling and testing among pregnant women at different levels of health facilities--experiences from a community-based study in Northern Vietnam

BACKGROUND

HIV counselling and testing for pregnant women is a key factor for successful prevention of mother to child transmission of HIV. Women's access to testing can be improved by scaling up the distribution of this service at all levels of health facilities. However, this strategy will only be effective if pregnant women are tested early and provided enough counselling.

OBJECTIVE

To assess early uptake of HIV testing and the provision of HIV counselling among pregnant women who attend antenatal care at primary and higher level health facilities.

METHODS

A community based study was conducted among 1108 nursing mothers. Data was collected during interviews using a structured questionnaire focused on socio-economic background, reproductive history, experience with antenatal HIV counselling and testing as well as types of health facility providing the services.

RESULTS

In all 91.0% of the women interviewed had attended antenatal care and 90.3% had been tested for HIV during their most recent pregnancy. Women who had their first antenatal checkup at primary health facilities were significantly more likely to be tested before 34 weeks of gestation (OR = 43.2, CI: 18.9-98.1). The reported HIV counselling provision was also higher at primary health facilities, where women in comparison with women attending higher level health facilities were nearly three or and four times more likely to receive pre-test (OR = 2.7; CI:2.1-3.5) and post-test counseling (OR = 4.0; CI: 2.3-6.8).

CONCLUSIONS

The results suggest that antenatal HIV counseling and testing can be scaled up to primary heath facilities and that such scaling up may enhance early uptake of testing and provision of counseling.

Preventing mother-to-child transmission in Guayaquil, Ecuador: HIV knowledge and risk perception

An important step in preventing mother-to-child transmission is testing pregnant women for HIV. Health literacy measures, such as HIV knowledge and risk perception, may determine which women are tested in prenatal clinics where routine opt-out testing is not available. A survey was conducted in Guayaquil, Ecuador in 2006 (n=485), where approximately 0.7% of HIV tests in prenatal clinics were positive. Pregnant women over the age of 18 were invited to complete the survey in the waiting rooms at four city hospitals. There were 67.2% of women reported being tested previously for HIV. The most notable finding was that women who perceived a risk were 1.74 times more likely to request testing (p=0.021), but a woman's risk perception was not related to established risk factors. In addition, a physician's recommendation would result in the testing of nearly all women (94.3%). This data suggest that interventions in prenatal care clinics should incorporate educational strategies to increase accurate perception of personal risk. These efforts must occur in conjunction with increasing the access to HIV tests to achieve the goal of universal prenatal testing.

Expanding HIV testing efforts in concentrated epidemic settings: a population-based survey from rural Vietnam

Background

To improve HIV prevention and care programs, it is important to understand the uptake of HIV testing and to identify population segments in need of increased HIV testing. This is particularly crucial in countries with concentrated HIV epidemics, where HIV prevalence continues to rise in the general population. This study analyzes determinants of HIV testing in a rural Vietnamese population in order to identify potential access barriers and areas for promoting HIV testing services.

Methods

A population-based cross-sectional survey of 1874 randomly sampled adults was linked to pregnancy, migration and economic cohort data from a demographic surveillance site (DSS). Multivariate logistic regression analysis was used to determine which factors were associated with having tested for HIV.

Results

The age-adjusted prevalence of ever-testing for HIV was 7.6%; however 79% of those who reported feeling at-risk of contracting HIV had never tested. In multivariate analysis, younger age (aOR 1.85, 95% CI 1.14–3.01), higher economic status (aOR 3.4, 95% CI 2.21–5.22), and semi-urban residence (aOR 2.37, 95% CI 1.53–3.66) were associated with having been tested for HIV. HIV testing rates did not differ between women of reproductive age who had recently been pregnant and those who had not.

Conclusions

We found low testing uptake (6%) among pregnant women despite an existing prevention of mother-to-child HIV testing policy, and lower-than-expected testing among persons who felt that they were at-risk of HIV. Poverty and residence in a more geographically remote location were associated with less HIV testing. In addition to current HIV testing strategies focusing on high-risk groups, we recommend targeting HIV testing in concentrated HIV epidemic settings to focus on a scaled-up provision of antenatal testing. Additional recommendations include removing financial and geographic access barriers to client-initiated testing, and encouraging provider-initiated testing of those who believe that they are at-risk of HIV.

HIV risk behaviours and determinants among people living with HIV/AIDS in Vietnam

There is a potentially high risk of HIV spreading from people living with HIV/AIDS. We conducted a cross-sectional study to examine HIV risk behaviours and their determinants among people living with HIV/AIDS. Eighty-two percent had been sexually active. Sex with multiple partners was reported by 20% and consistent condom use by about one third. More than half of the participants (52%) reported having injected drugs during the previous month, and 35% of those had shared needles and syringes. Voluntary HIV testing and having received condoms or injection equipment from the local HIV prevention program, were found to be significantly associated with fewer HIV risk behaviours. Having learned recently about personal HIV status, multiple sex partners, low educational attainment and young age were found to be associated with higher HIV risk behaviours. Giving high priority to targeted preventive and support programmes is likely to be a highly cost-effective strategy.

Attitudes About Prenatal Hiv Testing in Turkey

The aim of this study was to assess the attitudes of Turkish pregnant women and antenatal health care providers towards prenatal HIV testing. A self-administered questionnaire was used. The relationships between the different groups' knowledge and attitudes were analysed by using the chi-squared statistic. A total of 494 pregnant women and 181 care providers participated. Forty-four per cent of the pregnant women thought that prenatal HIV testing should be mandatory, and 84% of the health care providers thought it should be performed routinely or be mandatory. The majority of the pregnant women (74%) and half of the care providers agreed that the test results should be disclosed first to the pregnant woman. The study results also revealed that most of the prenatal care providers would not protect pregnant women's autonomy and privacy, contrary to the pregnant women's own preferences. It is essential to establish national prenatal HIV testing policies in order to prevent unethical practices and ensure satisfaction for pregnant women and health care providers.

Determinants of HIV counselling and testing participation in a prevention of mother-to-child transmission programme in rural Burkina Faso

OBJECTIVES

To analyse the factors associated with the uptake of HIV counselling, HIV testing and returning for test results in a rural hospital setting in Nouna, Burkina Faso.

METHODS

Cross sectional survey of 435 pregnant women who visited the district hospital for antenatal care, from July to December 2004. Separate multivariate logistic regression analyses including analysis of reported reasons were performed to identify the factors associated with accepting HIV counselling and testing.

RESULTS

HIV testing participation was related to discussing HIV screening with the partner (OR 8.36), and the number of antenatal care (ANC) visits already accomplished (OR 2.23). The quality of pre-test counselling was very poor as 42% did not understand the process. The absence of doctors and mismanagement of time for post-test counselling were the main reasons why women did not receive test results. Analysis of participants by discussion status, counselling and test participation revealed that fewer women dropped out at every stage who discussed HIV testing with their partner.

CONCLUSION

Communication with the partner plays a vital role in the uptake of HIV testing. Encouraging women to engage in a discussion about testing with their partners may be a viable intervention to improve participation. Quality of service needs to be better.

Barriers to the implementation of programs for the prevention of mother-to-child transmission of HIV: a cross-sectional survey in rural and urban Uganda

Background

Implementation of programs for the prevention of mother-to-child transmission (PMTCT) of HIV faces a variety of barriers and challenges. The assessment of these challenges has generally been conducted in large urban health facilities. As programs expand into rural areas, the potential barriers that may be encountered there also need to be assessed. This study examines potential barriers that might affect the acceptability of interventions for PMTCT in rural and urban settings.

Results

Four hundred and four women at a large urban hospital and three rural clinics that had recently started implementing PMTCT were interviewed. Level of knowledge of MTCT and preference for rapid HIV testing were equally high in both areas, but rural women had a higher tendency to think that they should consult their husbands before testing, with borderline statistical significance (72% vs. 64% p = 0.09). Health facility-based deliveries were significantly lower among mothers in rural areas compared to those in the urban setting. Overall, significant predictors of willingness to test for HIV were post-primary education (OR = 3.1 95% CI 1.2, 7.7) and knowledge about rapid HIV tests (OR = 1.8, 95% CI 1.01, 3.4). The strongest predictor of willingness to accept an HIV test was the woman's perception that her husband would approve of her testing for HIV. Women who thought their husbands would approve were almost six times more likely to report a willingness to be tested compared to those who thought their husbands would not approve (OR = 5.6, 95% CI 2.8, 11.2).

Conclusion

Lessons learned in large urban hospitals can be generalized to rural facilities, but the lower proportion of facility-based deliveries in rural areas needs to be addressed. Same-day results are likely to ensure high uptake of HIV testing services but male spousal involvement should be considered, particularly for rural areas. Universal Primary Education will support the success of PMTCT programs.
