Acceptance of HIV Testing Among Pregnant Women in Dar-es-Salaam, Tanzania

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.

Systematic review and meta-analysis of seroprevalence of human immunodeficiency virus serological markers among pregnant women in Africa, 1984-2020

BACKGROUND

Human immunodeficiency virus (HIV) is a major public health concern, particularly in Africa where HIV rates remain substantial. Pregnant women are at an increased risk of acquiring HIV, which has a significant impact on both maternal and child health.

AIM

To review summarizes HIV seroprevalence among pregnant women in Africa. It also identifies regional and clinical characteristics that contribute to study-specific estimates variation.

METHODS

The study included pregnant women from any African country or region, irrespective of their symptoms, and any study design conducted in any setting. Using electronic literature searches, articles published until February 2023 were reviewed. The quality of the included studies was evaluated. The DerSimonian and Laird random-effects model was applied to determine HIV pooled seroprevalence among pregnant women in Africa. Subgroup and sensitivity analyses were conducted to identify potential sources of heterogeneity. Heterogeneity was assessed with Cochran's Q test and I2 statistics, and publication bias was assessed with Egger's test.

RESULTS

A total of 248 studies conducted between 1984 and 2020 were included in the quantitative synthesis (meta-analysis). Out of the total studies, 146 (58.9%) had a low risk of bias and 102 (41.1%) had a moderate risk of bias. No HIV-positive pregnant women died in the included studies. The overall HIV seroprevalence in pregnant women was estimated to be 9.3% [95% confidence interval (CI): 8.3-10.3]. The subgroup analysis showed statistically significant heterogeneity across subgroups (P < 0.001), with the highest seroprevalence observed in Southern Africa (29.4%, 95%CI: 26.5-32.4) and the lowest seroprevalence observed in Northern Africa (0.7%, 95%CI: 0.3-1.3).

CONCLUSION

The review found that HIV seroprevalence among pregnant women in African countries remains significant, particularly in Southern African countries. This review can inform the development of targeted public health interventions to address high HIV seroprevalence in pregnant women in African countries.

Intimate partner violence and HIV testing during antenatal care: A latent class analysis to identify risk factors for HIV infection in mothers and their children in the United Republic of Tanzania

Intimate partner violence has adverse effects on mother's overall health and prevention of mother to child HIV transmission. To identify and examine subgroups of mothers experiencing intimate partner violence and the likelihood of HIV testing during antenatal care, we conducted a latent class analysis using data from the Tanzania Demographic and Health Survey 2010 (N = 2,809). Intimate partner violence included mother's experiences with partners' controlling behaviors, as well as emotional, physical, and sexual violence. The outcome was mother's accepting HIV testing offered during their antenatal care visit. Covariates included mother's level of education, rural/urban residence, and prevention of mother to child HIV transmission talk during antenatal care visit. The latent class analysis indicated a three-class solution was the best model and identified the following profiles: mothers with no experience of intimate partner violence (61% of sample) with a 90.5% likelihood of HIV testing; mothers with moderate levels of intimate partner violence (26%) with an 84.7% likelihood of testing; and mothers with extreme levels of intimate partner violence (13%) with an 82% likelihood of testing. An auxiliary multinomial logistic regression with selected covariates was conducted to further differentiate IPV profiles, where mothers with extreme levels of intimate partner violence had 57% increased odds [95%CI:1.06-2.33, p = .023] of living in rural areas compared to mothers with no experience of intimate partner violence. Our person-centered methodological approach provided a novel model to understand the impact of multiple intimate partner violence risk factors on antenatal care HIV testing to identify mothers in need of interventions and their children at highest for parent to child HIV transmission. Our model allows person-centered interventional designs tailored for the most at-risk subgroups within a population.

Inequalities in Access and Utilization of Maternal, Newborn and Child Health Services in sub-Saharan Africa: A Special Focus on Urban Settings

OBJECTIVES

The aim of this paper is to share the results of a systematic review on the state of inequalities in access to and utilization of maternal, newborn and child health (MNCH) services in the sub-Saharan African region. The focus of the review was on urban settings where growing needs and challenges have been registered over the past few years due to rapid increase in urban populations and urban slums.

METHODS

The review was conducted according to Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. Studies published in English between 2000 and 2019 were included. A narrative synthesis of both qualitative and quantitative data was undertaken. The record for registration in PROSPERO was CRD42019122066.

RESULTS

The review highlights a great variation in MNCH services utilization across urban sub-Saharan Africa (SSA). The main aspects of vulnerability to unequal and poor MNCH services utilization in urban settings of the region include poverty, low level of education, unemployment, lower socioeconomic status and poor livelihoods, younger maternal age, low social integration and social support, socio-cultural taboos, residing in slums, and being displaced, refugee, or migrant. At the health system level, persistent inequalities are associated with distance to health facility, availability of quality services and discriminating attitudes from health care personnel.

CONCLUSION

Context-specific intervention programs that aim at resolving the identified barriers to access and use MNCH services, particularly for the most vulnerable segments of urban populations, are essential to improve the overall health of the region and universal health coverage (UHC) targets.

Clients' Satisfaction with Services for Prevention of Mother-to-Child Transmission of HIV in Public Health Facilities in Diredawa City, Eastern Ethiopia

Background

Ethiopia has a very high burden of HIV infection among children, contracted from their mothers, and nearly two-thirds of pregnant women do not receive prevention of mother-to-child transmission (PMTCT) services. Ensuring clients’ satisfaction with PMTCT services is one of the bases to scale up service utilization and mitigate MTCT of HIV. However, in Ethiopia, particularly in the study area, evidence related to clients’ satisfaction with PMTCT services is scanty.

Methods

A facility-based cross-sectional study was conducted among women attending antenatal care in Diredawa city. Systematic random sampling was used to select 517 study participants. Interviewer-administered structured and pretested questionnaires were used to collect data. Statistical significance was regarded as P≤0.05 with a 95% CI.

Results

Client satisfaction with PMTCT services was 82.2% (95% CI 66.4%–94.3). Receiving the service from a hospital (AOR 2.34; 95% CI 1.5, 3.98), no formal education (AOR 2.53, 95% CI 1.52–4.2), primary education (AOR 2.17 95% CI 1.17–4.04), receiving pre- and post-HIV test counseling from the same provider (AOR 4.93, 95% CI 2.98–7.17), gestational age above first trimester (AOR 1.74, 95% CI 1.12–2.71), and waiting time ≤15 minutes (AOR 2.31, 95% CI 1.28–4.16) were positively associated with client satisfaction with PMTCT services.

Conclusion

Client satisfaction with PMTCT services is relatively high. Receiving the service from a hospital, no formal education or only primary education, gestational age above first trimester, getting pre- and post-HIV test counseling from the same provider, and waiting time ≤15 minutes to receive services were factors associated with client satisfaction. A greater number of skilled PMTCT-service providers would improve service quality and hasten its delivery. Furthermore, providing mentoring and supportive supervision of health centers with PMTCT programs and keeping the same provider in posttest counseling is also mandatory.

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.

Acceptance of HIV Counseling and Testing among Antenatal Clinic Attendees in Southern Ethiopia

Background

Counseling and testing for Human Immunodeficiency Virus (HIV) (HCT) during antenatal care (ANC) is a critical entry point for the prevention of mother-to-child transmission (PMTCT) of HIV. However, in Ethiopia limited evidence exists regarding the extent of acceptance of the service. The study aimed to assess the level and factors associated with acceptance of HCT in Hawassa city, Southern Ethiopia.

Methods

Cross-sectional study was conducted in four public health facilities found in the city. Five hundred and four ANC clients were selected using multistage sampling technique. Data were collected via interviewer administered questionnaire and analyzed using multivariable binary logistic regression analysis. The outputs are presented using adjusted odds ratio (AOR) with 95% confidence interval (CI).

Results

The vast majority, 84.1% (95% CI: 80.6-87.2%), of the respondents accepted the HCT. Acceptance was positively associated with being married [AOR=5.60 (95% CI: 1.87-16.50)], having two or more ANC visits [4.93 (95% CI: 2.40-10.07)], history of prior HIV testing [4.23 (95% CI: 1.90-9.74)], having good knowledge about MTCT [4.91 (95% CI: 2.07-11.6)] and PMTCT [6.22 (95% CI: 2.87-13.50)] and having no fear of stigma and discrimination [3.32 (95% CI: 1.57-7.02)].

Conclusion

Acceptance of HCT can be further improved by enhancing the knowledge of mother about PMTCT and combating stigma and discrimination.

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.

The cost-effectiveness of different feeding patterns combined with prompt treatments for preventing mother-to-child HIV transmission in South Africa: estimates from simulation modeling

Objectives

Based on the important changes in South Africa since 2009 and the Antiretroviral Treatment Guideline 2013 recommendations, we explored the cost-effectiveness of different strategy combinations according to the South African HIV-infected mothers' prompt treatments and different feeding patterns.

Study Design

A decision analytic model was applied to simulate cohorts of 10,000 HIV-infected pregnant women to compare the cost-effectiveness of two different HIV strategy combinations: (1) Women were tested and treated promptly at any time during pregnancy (Promptly treated cohort). (2) Women did not get testing or treatment until after delivery and appropriate standard treatments were offered as a remedy (Remedy cohort). Replacement feeding or exclusive breastfeeding was assigned in both strategies. Outcome measures included the number of infant HIV cases averted, the cost per infant HIV case averted, and the cost per life year(LY) saved from the interventions. One-way and multivariate sensitivity analyses were performed to estimate the uncertainty ranges of all outcomes.

Results

The remedy strategy does not particularly cost-effective. Compared with the untreated baseline cohort which leads to 1127 infected infants, 698 (61.93%) and 110 (9.76%) of pediatric HIV cases are averted in the promptly treated cohort and remedy cohort respectively, with incremental cost-effectiveness of $68.51 and $118.33 per LY, respectively. With or without the antenatal testing and treatments, breastfeeding is less cost-effective ($193.26 per LY) than replacement feeding ($134.88 per LY), without considering the impact of willingness to pay.

Conclusion

Compared with the prompt treatments, remedy in labor or during the postnatal period is less cost-effective. Antenatal HIV testing and prompt treatments and avoiding breastfeeding are the best strategies. Although encouraging mothers to practice replacement feeding in South Africa is far from easy and the advantages of breastfeeding can not be ignored, we still suggest choosing replacement feeding as far as possible.

HIV testing among pregnant wives of migrant men in a rural district of India: urgent call for scale up

In India, despite the fact that more pregnant women are being tested for HIV under the purview of the Prevention of Parent-to-Child HIV Transmission program, official figures indicate low rates of HIV testing, evidencing missed opportunities for HIV prevention. The present study examined the prevalence of HIV testing and the barriers to testing among pregnant women, whose vulnerability to HIV is enhanced by their spouses' risky behaviors. A cross-sectional study was conducted from November 2010 to January 2011 among 357 women who had given birth in the last two years in a district in Orissa. Only one-third of women had been tested for HIV during pregnancy. Women with more than six years of education (OR: 2.39, 95% CI: 1.06-5.39), having knowledge of sexually transmitted infections (OR: 12.37, 95% CI: 5.55-27.58), having discussions with spouses about HIV (OR: 3.56, 95% CI: 1.61-7.86), and seeking antenatal care in government district hospitals and private clinics as opposed to peripheral community health centers, were more likely to receive HIV testing during pregnancy. The findings point to the need to widen HIV testing to community-based services, increase coverage of HIV/sexually transmitted infection awareness and prevention programs, and encourage spousal communication through quality counseling.

Determinants for refusal of HIV testing among women attending for antenatal care in Gambella Region, Ethiopia

Background

In Gambella region, inhabitants owe socio-cultural factors that might favor refusal for HIV testing service utilization among Antenatal Care attendees.

Objective

To assess determinants for refusal of HIV testing service utilization among ANC attendees in Gambella Region.

Methods

A comparative cross sectional study was conducted among ANC attendees from March 2008 to May 2008 in four selected health facilities of Gambella region. Sample size of 332 participants (83 who refused HIV testing and 249 who accepted HIV testing) were taken for the study. The study was supplemented with four focus group discussions. Multivariate binary logistic regression was employed to control for confounding factors.

Results

When adjusted with other factors pregnant women with 2–3 live births in the past; who claimed divorce as a perceived response of their husband following HIV positive test result; who had not sought agreement from their husband for testing; disclosure of test for husband and being from certain ethnic group (E.g. Mejenger) were independent predictors for refusal of HIV testing among ANC attendees.

Conclusion and recommendation

Based on the findings, the following recommendations were forwarded: Provision of innovative information and education on the pre-test session for those pregnant women having two or more children; community involvement to tackle stigma; women empowerment; designing couple friendly counseling service; and fighting harmful traditional practices related with decision of HIV testing.

Acceptability of prenatal HIV screening at the primary care level in Nigeria

A survey of 333 pregnant women receiving antenatal care at the primary healthcare centres in Sagamu Local Government Area of Ogun State, southwest Nigeria was conducted between January and March 2005 to assess the acceptability of prenatal HIV screening among them. A total of 325 (97.8%) of the respondents were aware of HIV/AIDS but only 181 (54.3%) of them believed it is a problem in Nigeria. A total of 257 (77.2%) respondents agreed to undergo voluntary counselling and HIV testing (VCT). Multivariate logistic regression analysis of associated factors indicated that being married, self-perception of no risk of HIV infection, awareness of benefits of prenatal HIV testing and Christianity are independent predictors of acceptance of prenatal HIV testing in this population. Most of the respondents (78.9%) who were unwilling to take the test cited fear of being infected with its consequences of stigma and discrimination as the reason for their attitude. The survey suggests that a successful integration of VCT programme into the existing primary healthcare services for prevention of vertical HIV transmission is feasible in this part of Nigeria.

Prevalence and predictors of failure to return for HIV-1 post-test counseling in the era of antiretroviral therapy in rural Kilimanjaro, Tanzania: challenges and opportunities

In this era of antiretroviral therapy (ART) a limited number of population-based studies have investigated the extent of voluntary counseling and testing acceptance and completion in Africa. The aim of this study was to assess the prevalence and predictors of failure to return for HIV post-test counseling (PTC) among adults in rural Kilimanjaro, Tanzania. Following a cross-sectional survey, people aged 15-44 years living in Oria village were interviewed and offered individual HIV-1 pre-test counseling. They were asked to return for PTC two weeks after blood sample collection. HIV-1 testing was accepted by 1491 (97.6%) of participants with 98.9% expressing desire to know their results. The proportion of individuals who did not return for PTC was 50.9%. These proportions did not differ by sex. Seropositive HIV result (AOR: 2.2; 95%CI: 1.3-4.3 for women and AOR: 2.1, 95%CI: 1.2-5.7 for men), low HIV/AIDS-transmission and ART availability knowledge, perceived low risk of HIV infection, not accepting to share results (men only) and inability to self-prevent HIV infection (women only) predicted failure to return for PTC. Additionally, participants were more likely not to return for PTC if they had no-formal education or reported recent sexual-risk behaviors, for both sexes. Age, prior HIV testing or AIDS-related clinical symptoms were not associated with return for PTC in this population. These findings suggest that low returns for PTC, especially for HIV-seropositive individuals, result in a substantial missed opportunity for prevention and care. Knowledge of ART accessibility is necessary but not sufficient to promote adequate return for PTC. The high attendance for pre-test counseling should be utilized to identify potential individuals who may not return for PTC and to promote risk reduction and care.

Determinants of nonadherence to a single-dose nevirapine regimen for the prevention of mother-to-child HIV transmission in Rwanda

OBJECTIVES

To describe experiences, and identify factors associated with nonadherence to a single-dose nevirapine (SD-NVP) regimen for the prevention of mother-to-child transmission (PMTCT) of HIV in Rwanda.

METHODS

In April to May 2006, using a case-control design at 12 PMTCT sites, we interviewed HIV-infected women who did not adhere (n = 111) and who adhered (n = 125) to the PMTCT prophylaxis regimen. Nonadherence was defined as mother and/or infant not ingesting SD-NVP at the recommended time or not at all and adherence as mother-infant pairs who ingested it as recommended.

RESULTS

Only 61% of nonadherent women had received SD-NVP during pregnancy or delivery. Among nonadherent women who received SD-NVP, 80% ingested it at the recommended time, representing 49% of all nonadherent women. Only 7% of their newborns ingested SD-NVP. Multivariate logistic regression showed that unmarried women, less educated women, women who made 2 or less antenatal care visits, and those offered HIV testing after their first antenatal care visit were more likely to be nonadherent to PMTCT prophylaxis. Not disclosing one's HIV status to someone aside from a partner was also associated with nonadherence in mother-infant pairs.

CONCLUSIONS

Sociodemographic factors, health services delivery factors, and a lack of communication and social support contributed to nonadherence to PMTCT prophylaxis in Rwanda.

Acceptance of HIV testing among women attending antenatal care in south-western Uganda: risk factors and reasons for test refusal

A problem commonly encountered in programs for prevention of mother-to-child-transmission (PMTCT) of HIV in sub-Saharan Africa is low rates of HIV test acceptance among pregnant women. In this study, we examined risk factors and reasons for HIV test refusal among 432 women attending three antenatal care clinics offering PMTCT in urban and semi-urban parts of the Mbarara district, Uganda. Structured interviews were performed following pre-test counselling. Three-hundred-eighty women were included in the study, 323 (85%) of whom accepted HIV testing. In multivariate analysis, testing site (Site A: OR = 1.0; Site B: OR = 3.08; 95%CI: 1.12-8.46; Site C: OR = 5.93; 95%CI: 2.94-11.98), age between 30 and 34 years (<20 years: OR = 1.0; 20-24 years: OR = 1.81; 95%CI: 0.58-5.67; 25-29 years: OR = 2.15; 95%CI: 0.66-6.97; 30-34 years: OR = 3.88; 95%CI: 1.21-13.41), mistrust in reliability of the HIV test (OR = 20.60; 95%CI: 3.24-131.0) and not having been tested for HIV previously (OR = 2.15; 95%CI: 1.02-4.54) were associated with test refusal. Testing sites operating for longer durations had higher rates of acceptance. The most common reasons claimed for test refusal were: lack of access to antiretroviral therapy (ART) for HIV-infected women (88%; n=57), a need to discuss with partner before decision (82%; n=57) and fear of partner's reaction (54%; n=57). Comparison with previous periods showed that the acceptance rate increased with the duration of the program. Our study identified risk factors for HIV test refusal among pregnant women in Uganda and common reasons for not accepting testing. These findings may suggest modifications and improvements in the performance of HIV testing in this and similar populations.

Investigating factors associated with uptake of HIV voluntary counselling and testing among pregnant women living in North Uganda

We investigated factors potentially associated with the uptake of HIV voluntary counselling and testing (VCT), which is the first step in acceding to programmes for the prevention of mother-to-child transmission of HIV infection. For the period 2001-2003, we estimated the VCT uptake among the 12,252 first-time attendees of the Antenatal Clinic (ANC) at Lacor Hospital (Gulu District, North Uganda). Associations between VCT uptake and socio-demographic characteristics and reproductive history were evaluated using log binomial regression models. VCT uptake was 55.6% for the overall study period; it increased from 51.0% in 2001 to 58.6% in 2002 and 57.7% in 2003 (P <0.001). Having some education [primary versus none, adjusted prevalence proportion ratio (PPR) =1.05, 95% confidence intervals (CI): 1.00-1.10] and being unmarried (cohabitating, PPR =1.07, 95% CI: 1.03-1.10; single/widowed/divorced, PPR =1.10, 95% CI: 1.03-1.18) were significantly associated with VCT uptake. Associations of borderline significance were found for: recent change of residence, having a partner with a modern occupation, and past use of contraceptives. VCT uptake is still low in this district of North Uganda. Although some socio-demographic factors were found to have been associated with uptake, the associations were weak and not of public-health significance.

Poverty and Devastation of Intimate Relations: Tanzanian Women’s Experience of Living With HIV/AIDS

In Tanzania, women of reproductive age constitute the largest group infected by HIV. This study aimed to explore the lived experiences related to health and sexuality of Tanzanian women who had known their positive serostatus for 1 year. In-depth interviews with 10 women were analyzed using a phenomenological-hermeneutic approach and showed frustration and despair at not having resources to maintain daily life. The women needed regular medical treatment for themselves and for their HIV-positive children. Their sexual desires had declined or vanished, and they had come to view sexuality as a source of transmittable disease. For some women, casual sex was an option to solve urgent financial needs. Happiness was something for their children, not for them. Access to social support from the women's community would help prevent further HIV transmission and enhance survival so the children could grow up with at least one devoted parent.

Antiretroviral therapy in resource-poor settings. Decreasing barriers to access and promoting adherence

Since 2002, the HIV Equity Initiative of the nongovernmental organization Partners in Health has been expanded in conjunction with the Haitian MOH to cover 7 public clinics. More than 8000 HIV-positive persons, 2300 of whom are on antiretroviral therapy (ART) are now followed. This article describes the interventions to promote access to care and adherence to ART developed in reference to the specific context of poverty in rural Haiti. User fees for clinic attendance have been waived for all patients with HIV and tuberculosis and for women presenting for prenatal services. Additionally, HIV testing has been integrated into the provision of primary care services to increase HIV case finding among those presenting to clinic because of illness, rather than solely focusing on those who present for voluntary counseling and testing (VCT). Once a patient is diagnosed with HIV, medications and monitoring tests are provided free of charge and transportation costs for follow-up appointments are covered to defray patients' out-of-pocket expenses. Patients are given home-based adherence support from a network of health workers who provide psychosocial support and directly observed therapy. In addition, the neediest patients receive nutritional support. Following the description of the program is an approximation of the costs of these interventions and a discussion of their impact.

Update: preventing mother-to-child transmission of HIV

The success of antiretroviral therapies for prevention of mother-to-child transmission of HIV in the developed world has prompted a wide array of research efforts, from improved implementation of voluntary counseling and testing programs to innovative approaches for short-course peripartum prophylaxis to understanding the dynamics of HIV transmission via breastfeeding. Clinical trials of modified short-course peripartum regimens which are applicable to resource-limited areas are demonstrating much lower transmission rates and preliminary data are emerging on limiting transmission via breastfeeding. Some of the most recent data on these topics are reviewed. Primary prevention of HIV in women of childbearing age combined with efforts to prevent mother-to-child transmission of HIV offer the best hope for addressing the burden of HIV in women and children.

Quality and quantity of antenatal HIV counselling in a PMTCT programme in Mombasa, Kenya

A recent report from a PMTCT implementation study in Mombasa, Kenya, points at an important gap between the efficacy in clinical trial circumstances and the effectiveness of PMTCT programmes when implemented in real life. Hence, the quality and quantity of antenatal HIV counselling in a routine setting were appraised. The counsellors' social and communicative skills, duration and topics covered during pre- and post-test counselling sessions were assessed by means of the VCT assessment tools published by UNAIDS. A total of 14 group educational sessions, 66 pre-test counselling sessions and 50 post-test counselling sessions were observed and assessed. In general, the frequency and duration of the counselling was low. Crucial topics such as window period and partner involvement and follow-up support were covered haphazardly. The counsellor's social and communicative skills were given high marks, yet information was rarely repeated or summarized. The limited time dedicated to women receiving antenatal VCT contrasts with the heavy and comprehensive load of health information and advice they are supposed to receive. Ample pre- and post-test counselling including follow-up should be pursued for optimal effectiveness of PMTCT. We propose a number of health system interventions preceded and guided by ongoing audit.

Antenatal HIV testing in rural eastern Uganda in 2003: incomplete rollout of the prevention of mother-to-child transmission of HIV programme?

Background

Uganda began to implement the prevention of mother-to-child transmission (PMTCT) of HIV programme in 2000, and by the end of 2003 it had expanded to cover 38 of the 56 districts including Mbale District. However, reports from Mbale Hospital showed that less than 10% of pregnant women accepted antenatal HIV testing. We therefore conducted a study to determine the proportion of pregnant women who tested for HIV and the gaps and barriers in PMTCT implementation.

Methods

The study was a cross sectional household survey of women aged 18 years or more, with children aged one year or less, who resided in Mbale Town or in the surrounding Bungokho County. We also conducted in-depth interviews with six health workers in Mbale Hospital.

Results

In 2003, we interviewed 457 women with a median age of 24 years. The prevalence of antenatal HIV testing was 10 percent. The barriers to antenatal HIV testing were unavailability of voluntary counselling and testing services (44%), lack of HIV counselling (42%) and perceived lack of benefits for HIV infected women and their infants. Primipara (OR 2.6, 95% CI 1.2–5.8), urban dwellers (OR 2.7, 95% CI 1.3–5.8), women having been counselled on HIV (OR 6.2, 95% CI 2.9–13.2), and women with husbands being their primary confidant (OR 2.3, 95% CI 1.0–5.5) were independently associated with HIV testing.

Conclusion

The major barriers to PMTCT implementation were unavailability of PMTCT services, particularly in rural clinics, and poor antenatal counselling and HIV testing services. We recommend that the focus of the prevention of mother-to-child transmission of HIV programme should shift to the district and sub-district levels, strengthen community mobilization, improve the quality of antenatal voluntary counselling and HIV testing services, use professional and peer counsellors to augment HIV counselling, and ensure follow-up care and support for HIV positive women and their infants.

Measuring trends in prevalence and incidence of HIV infection in countries with generalised epidemics

OBJECTIVE

Review of recent data and practice to derive guidance on questions relating to the measurement and analysis of trends in HIV prevalence and incidence.

RESULTS

HIV prevalence among pregnant women attending antenatal clinics (ANCs) remains the principal data source to inform trends in the epidemic. Other data sources are: less available, representative of a small section of the population (sex workers, occupational groups), subject to additional bias (for example, voluntary counselling and testing service statistics), or are not yet available for multiple years (national surveys). Validity of HIV prevalence results may change over time due to improvements in HIV tests per se and implementation of laboratory quality assurance systems. The newer laboratory tests for recent infections require further validation and development of methodology to derive estimates of HIV incidence.

CONCLUSIONS

Issues to consider during statistical analyses of trends among ANC attendees are: inclusion of consistent sites only, use of confidence intervals, stratification by site when performing a statistical test for trend, the need for at least three observations in a surveillance system with data collection every one to two years, and sound judgement. Trends in HIV prevalence among pregnant 15-24 year olds attending ANCs can be used to approximate trends in incidence. Indepth small area research studies are useful to inform the interpretation of surveillance data and provide directly measured trends in prevalence and incidence. Modelling can assess changes over time in prevalence, incidence, and mortality at the same time. Modelling tools need to be further developed to allow incorporation of estimates of HIV incidence and mortality, as these data are likely to become available in the future. To increase their explanatory power, models should also be extended to incorporate programmatic inputs.
