Access to appropriate information on HIV is important in maximizing the acceptance of the antenatal HIV antibody test

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.

Associated factors of willingness to undergo routine chlamydia trachomatis screening among hospital-based patients in Shenzhen, China: a cross-sectional study

BACKGROUND

Chlamydia trachomatis (CT) is a common sexually transmitted infection (STI) with significant morbidity. The study aimed to explore the willingness to undergo routine CT screening and its associated factors among hospital-based patients in Shenzhen.

METHODS

We used data from the Shenzhen Gonorrhea and Chlamydia Intervention Programme. Participants were recruited with a stratified purposeful sampling design from 1 April 2018 to 16 May 2018. A structured questionnaire was used to obtain data on baseline characteristics and CT-related participant information.

RESULTS

Of the 16,546 participants, 64.79% were women, with a mean age of 31.85 ± 7.31 of all participants. Of the participants, 88.78% were willing to undergo routine CT screening. According to multivariate logistic regression analyses, willingness to undergo routine CT screening was associated with the following (P < 0.05): being a woman (AOR = 1.53, 95% CI = 1.34-1.75), one year or more residency in Shenzhen (AOR = 1.64, 95% CI = 1.37-1.95), any secondary education (AOR = 2.46, 95% CI = 1.92-3.15), monthly income ≥ RMB 10,000 (AOR = 1.24, 95% CI = 1.01-1.51), having forgotten CT diagnosis history (AOR = 1.42, 95% CI = 1.12-1.79), without current STI-related symptoms (AOR = 1.24, 95% CI = 1.10-1.41), and having correct understanding of the sequelae of CT infection (AOR = 1.68, 95% CI = 1.39-2.03).

CONCLUSION

This study reported high willingness to undergo routine CT screening among hospital-based patients in Shenzhen, and provided evidence for the promotion and the implementation of strategies and recommendations on routine CT screening in China.

Women's willingness to be tested for human immunodeficiency virus during pregnancy: A review

Mother-to-child-transmission of human immunodeficiency virus (HIV) is a primary cause of pediatric infections with HIV. Many of these infections involve women who were not tested early enough in pregnancy, or who did not receive prevention services. HIV testing of pregnant women is considered to be one of the key strategies for preventing mother-to-child-transmission of HIV, but HIV testing rates among pregnant women in various countries remain suboptimal. Understanding the factors relating to women's willingness to be tested for HIV during pregnancy is critical for developing strategies to increase HIV testing rates among pregnant women. Extensive research points to various factors relating to women's willingness to be tested for HIV during pregnancy, and various recommendations aimed at improving testing rates among pregnant women have been suggested based on the research. In light of the goals set by the United Nations to reduce the rate of infants infected with HIV, it is necessary to summarize what is currently known regarding factors related to women's willingness to be tested for HIV during pregnancy. The purpose of this review is therefore to examine factors related to women's willingness to be tested for HIV during pregnancy, and to summarize recommendations for practice and further research.

Accelerating prevention of mother-to-child transmission of HIV: ten-year experience of universal antenatal HIV testing programme in a low HIV prevalence setting in Hong Kong

Hong Kong has a low prevalence of HIV infection at less than 0.01%. Universal Antenatal HIV Testing Programme (UATP) was launched in all public antenatal units in September 2001. In 2008, voluntary rapid HIV testing was introduced in all public labour units to fill up the gap for pregnant women without HIV testing during the antenatal period. This study evaluated the performance of UATP and rapid HIV testing with indicators. From September 2001 to December 2011, process and outcome indicators for monitoring and evaluation were collected from the service providers in the form of monthly return of workload statistics and case-based statistics of each identified HIV-positive pregnancy via reporting forms. A total of 479,160 antenatal HIV tests and 2,675 rapid tests were performed in the study period. The acceptance rate for UATP and rapid HIV testing was 98% and 80.4% respectively. With the implementation of rapid HIV testing in January 2008, the proportion of pregnant women with HIV status discerned before delivery increased from 84.9% in 2006 to over 99.5% since 2008. The HIV prevalence in UATP and rapid HIV testing was 0.02% and 0.1% respectively. Fifty-three (68%) out of 78 HIV-infected pregnant women identified from the programme have delivered locally. Forty-three (81%) of them delivered by caesarean section and 50 (94%) of them were given antiretrovirals for intervention. Only three children born before the implementation of rapid HIV testing were HIV-infected. In conclusion, UATP and its rapid HIV testing component have been highly accepted and effective in the prevention of perinatal HIV transmission in Hong Kong.

Trends and Barriers to HIV Testing Among Tuberculosis Patients in Prey Kabas Operational District, Takeo Province, Cambodia

Data for this study were obtained from 2375 tuberculosis (TB) patients registered during 2007-2009 and 43 health providers to examine the trend of TB patient referral for HIV (human immunodeficiency virus) testing and to investigate provider-associated barriers to the referral in Prey Kabas operational district, Takeo province, Cambodia. Referral rate for HIV testing was 4.4% (30/684) in 2007, 15.4% (116/751) in 2008, and 30.1% (283/940) in 2009, with a significant upward trend over the period of time ( P = .009). The main barriers perceived by health providers were poor knowledge about TB/HIV, lack of communication skills, absence of any target plan for TB patient referral for HIV testing, and fear associated with informing positive test results to the TB patients and the associated stigma. Strategies to raise awareness about HIV/AIDS/TB among TB patients and their providers may improve the current state of low referral and its barriers in Cambodia.

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.

Addressing the slow uptake of HIV testing in Malawi: the role of stigma, self-efficacy, and knowledge in the Malawi BRIDGE Project

This study was carried out to test the hypothesis that HIV-related stigma would function as a barrier to uptake of HIV testing and that knowledge and self-efficacy would serve as facilitators. We also hypothesized that exposure to a behavior-change campaign would be associated with lower levels of stigma and higher levels of knowledge and self-efficacy. We conducted two separate cross-sectional surveys as part of the Malawi BRIDGE Project, including one at baseline in eight districts (n = 891), and another at mid-term in four districts in Malawi (n = 881). HIV-related knowledge, self-efficacy, and lack of stigma were positively associated with HIV testing. A positive association was also found between program exposure, on one hand, and knowledge, self-efficacy, and lack of stigma, on the other. These findings suggest that important psychosocial variables are linked with people's likelihood of HIV testing, and that these variables may be influenced by behavior-change programs.

Correlates of HIV/STD testing and willingness to test among rural-to-urban migrants in China

This study investigates socio-demographic, behavioral, psychological, and structural factors associated with self-reported HIV/STD testing and willingness to test among 1,938 Chinese migrants. Overall, 6% and 14% of participants had ever been tested for HIV and STD, respectively. The results of multivariate analyses indicate that working at entertainment sectors, engaging in commercial sex, and utilization of health care were positively associated with both HIV and STD testing. Younger age, selling blood, perceived peer sexual risk involvement, and satisfaction with life were associated with HIV testing only. Female gender, early sexual debut, multiple sexual partners, and perceived vulnerability to HIV/STD were associated with STD testing only. Male gender, having premarital sex, perceived higher severity of and vulnerability to HIV/STD, and utilization of health care were associated with willingness to be tested for both HIV and STD. Interventions designed to raise the perception of vulnerability to HIV/STD and to improve access to and utilization of health care may be effective in encouraging more HIV testing in this vulnerable population.

Barriers for introducing HIV testing among tuberculosis patients in Jogjakarta, Indonesia: a qualitative study

Background

HIV and HIV-TB co-infection are slowly increasing in Indonesia. WHO recommends HIV testing among TB patients as a key response to the dual HIV-TB epidemic. Concerns over potential negative impacts to TB control and lack of operational clarity have hindered progress. We investigated the barriers and opportunities for introducing HIV testing perceived by TB patients and providers in Jogjakarta, Indonesia.

Methods

We offered Voluntary Counselling and Testing (VCT) to TB patients in parallel to a HIV prevalence survey. We conducted in-depth interviews with 33 TB patients, 3 specialist physicians and 3 disease control managers. We also conducted 4 Focus Group Discussions (FGDs) with nurses. All interviews and FGDs were recorded and data analysis was supported by the QSR N6^® software.

Results

Patients' and providers' knowledge regarding HIV was poor. The main barriers perceived by patients were: burden for accessing VCT and fear of knowing the test results. Stigma caused concerns among providers, but did not play much role in patients' attitude towards VCT. The main barriers perceived by providers were communication, patients feeling offended, stigmatization and additional burden.

Conclusion

Introduction of HIV testing among TB patients in Indonesia should be accompanied by patient and provider education as well as providing conditions for effective communication.

Willingness to seek HIV testing and counseling among pregnant women attending antenatal clinics in Ogun State, Nigeria

HIV counseling and testing (CT) is slowly being introduced as one of several key components of the comprehensive package of HIV/AIDS prevention and care in Nigeria, particularly in the prevention of mother-to-child transmission of HIV (PMTCT). A cross-sectional survey of 804 women attending antenatal clinics (ANC) in Ogun State, Nigeria was done using questionnaires to assess their willingness to seek and undergo CT and know the determinants. Focus group discussions were also held in the general community: 84.3% of respondents believed in AIDS reality, while 24.3% thought they were at risk of HIV infection. Only 27% knew about MTCT, while 69.7% of 723 who had heard of HIV/AIDS did not know about CT. Only 71 (8.8%) had thought about CT and 33 (4.5%) mentioned HIV testing as one of antenatal tests. After health education on CT, 89% of the women expressed willingness to be tested. Their willingness for CT was positively associated with education (p < 0.05), ranging from 77% (no education) to 93% (post-secondary). More of those with self-perceived risk expressed willingness to test for HIV (p < 0.05). Those willing to be tested had a higher knowledge score on how HIV spreads than those not willing. Multiple regressions identified four key factors that were associated with willingness for CT: increasing educational level; not fearing a blood test; perception that the clinic offered privacy; and perceptions of higher levels of social support from relatives and peers. Those unwilling or undecided about CT expressed strong fear of social stigma/rejection if tested positive. The results provided insights for planning promotional programs and showed that not only are IEC efforts needed to boost knowledge about HIV/AIDS, but that change in clinic setting and community are imperative in creating supportive environment to encourage uptake of CT services.

Knowledge and attitude toward HIV voluntary counseling and testing services among pregnant women attending an antenatal clinic in Sudan

Human immunodeficiency virus (HIV) infection and the development of the acquired immunodeficiency syndrome (AIDS) are increasing at an alarming rate especially in the sub-Saharan region. Pregnant women susceptible to HIV and its transmission to the fetus provide a unique opportunity for implementing preventive strategy against HIV infection of newborn babies. During the period of August-December 2005 a cross-sectional study was conducted at the Fath-Elrahman Elbashir antenatal clinic, Khartoum Teaching Hospital, to investigate pregnant women's basic knowledge and attitude toward HIV and mother to child transmission as well as voluntary counseling and testing. Pre-tested structured questionnaires were given to antenatal attendants by professional counselors. Their basic socio-demographic and obstetric characteristics were obtained. Respondents' knowledge about HIV and mother to child transmission were tested. In addition, their willingness toward HIV testing was also reported. Out of the 1,005 women investigated, 79% had basic knowledge about HIV. Those who were resident in Khartoum and whose age was > or =26.1 years and their education level was secondary and above were found to be more knowledgeable about HIV. More than half of respondents were aware of mother to child transmission. Older (> or =26.1 years), educated, and working mothers were found to be more knowledgeable about mother to child transmission. Willingness to undergo the test was demonstrated in 72.8% of respondents. However, only 30.3% had the test done. Older women, primigravidae, and Muslims have higher acceptance of voluntary counseling and testing. There is a need to extend the voluntary counseling and testing program in all antenatal clinics. In addition, there is a need to increase the level of education and raise health awareness about HIV and mother to child transmission.

Social and psychological factors associated with willingness to test for HIV infection among young people in Botswana

In spite of extensive campaigns to promote voluntary counselling and testing through the radio, television, newspapers and mass rallies, testing for HIV remains a challenge in Botswana. Using a representative sample of 1,294 students from secondary schools and tertiary institutions, the study investigates the effects of socio-demographic background variables, family coherence, interpersonal relations, sexual experience and knowledge about sexual health, on willingness to test for HIV infection. The results show that willingness to test for HIV infection was negatively associated with being sexually active and having a number of partners. Indicators of family, coherence, psychological bonding and personal adjustment such as common residence among parents, emotional support from the family attachment to parents, happiness with life in general and satisfaction with life as a student were associated with willingness to test. The importance of sexual activity, number of partners, happiness with life in general, level of attachment to father and physical fights with other children were identified as the social and psychological predictors of willingness to test for HIV using multiple logistic regression. The study highlights the importance of continued education about voluntary counselling and testing among sexually active young people, especially those from poorer backgrounds in rural areas.
