Determinants of antenatal HIV testing in the opt-out approach in Nigeria: findings from the Nigerian Demographic and Health Survey

Geographic variation in missed opportunities for the prevention of mother-to-child transmission of HIV among women receiving antenatal care in Nigeria

There are missed opportunities for the prevention of mother-to-child transmission of HIV (PMTCT) in Nigeria. However, little is known about the geographic variation. We examined the geographic pattern in the missed opportunities for HIV testing among antenatal care (ANC) attendees and initiation t on antiretroviral therapy (ART) in Nigeria. This study was an analysis of aggregated state-level data on 2,875,370 ANC attendees from the 2019 national HIV/AIDS health sector data. We performed descriptive statistics and explanatory spatial data analysis. Overall, the missed opportunity for HIV testing was 9.3%, ranging from 1.8% in the South South to 14.5% in the North West. The missed opportunity for HIV testing ranged from 0.2% in Imo State to 25.2% in Kaduna State. The local indicator of spatial association cluster map showed a concentration of cold spots in the South and hot spots in the North. The overall missed opportunity for ART was 9.5%, ranging from 7.4% in the South West to 11.1% in the NorthCentral. It was lowest in Adamawa State (0%), while Enugu State had the highest (32.2%). Missed opportunities for PMTCT among women attending ANC in Nigeria occur at varying degrees across the states, with higher levels in the northern region.

Prenatal care coverage and correlates of HIV testing in sub-Saharan Africa: Insight from demographic and health surveys of 16 countries

Background

Prenatal screening of pregnant women for HIV is central to eliminating mother-to-child-transmission (MTCT) of HIV. While some countries in sub-Saharan Africa (SSA) have scaled up their prevention of MTCT programmes, ensuring a near-universal prenatal care HIV testing, and recording a significant reduction in new infection among children, several others have poor outcomes due to inadequate testing. We conducted a multi-country analysis of demographic and health surveys (DHS) to assess the coverage of HIV testing during pregnancy and also examine the factors associated with uptake.

Methods

We analysed data of 64,933 women from 16 SSA countries with recent DHS datasets (2015–2018) using Stata version 16. Adjusted and unadjusted logistic regression models were used to examine correlates of prenatal care uptake of HIV testing. Statistical significance was set at p<0.05.

Results

Progress in scaling up of prenatal care HIV testing was uneven across SSA, with only 6.1% of pregnant women tested in Chad compared to 98.1% in Rwanda. While inequality in access to HIV testing among pregnant women is pervasive in most SSA countries and particularly in West and Central Africa sub-regions, a few countries, including Rwanda, South Africa, Zimbabwe, Malawi and Zambia have managed to eliminate wealth and rural-urban inequalities in access to prenatal care HIV testing.

Conclusion

Our findings highlight the between countries and sub-regional disparities in prenatal care uptake of HIV testing in SSA. Even though no country has universal coverage of prenatal care HIV testing, East and Southern African regions have made remarkable progress towards ensuring no pregnant woman is left untested. However, the West and Central Africa regions had low coverage of prenatal care testing, with the rich and well educated having better access to testing, while the poor rarely tested. Addressing the inequitable access and coverage of HIV testing among pregnant women is vital in these sub-regions.

Low coverage of HIV testing among adolescents and young adults in Nigeria: Implication for achieving the UNAIDS first 95

Background

Most studies on HIV testing among young people in Nigeria are not nationally representative. As such, recent nationally representative data, such as the Multiple Indicator Cluster Survey (MICS), could help assess the current level of HIV testing among young people, a key target population for HIV prevention in the country. In this study, we examined the coverage and factors associated with HIV testing among adolescents and young adults (AYA).

Methods

We used the data for 14,312 AYA that examined recent and lifetime HIV testing from the 2017 MCIS. Our outcomes of interest were ever tested for HIV and recently tested for HIV. We examined the association between socio-demographic factors (e.g., age, marital status, education attainment, wealth status), stigma belief, exposure to media and HIV knowledge, and uptake of HIV testing using adjusted and unadjusted logistic regression models.

Results

Less than a quarter of the AYA (23.7%) had ever tested for HIV, and an even lower proportion (12.4%) tested in the year preceding the survey. More females (25.4%) compared to males (20.8%) had ever tested for HIV. Young people who were aged 20–24 years (AOR 1.52, 95% CI 1.34–1.72), married (AOR 2.42, 95% CI 1.98–2.97), had higher educational attainment (AOR 5.85, 95% CI 4.39–7.81), and belonged to the wealthiest quintile (AOR 1.99, 95% CI 1.53–2.60), had higher odds of having ever tested for HIV compared to those aged 15–19 years, never married, had no formal education and belonged to the poorest wealth quintile. Also, those who had positive stigma belief towards people living with HIV (AOR 2.93, 95% CI 2.47–3.49), had higher HIV knowledge (AOR 1.62, 95% CI 1.24–2.11), and higher media exposure (AOR 1.64, 95% CI 1.36–1.97), had higher odds of having ever tested compared to those who had more negative stigma belief, had low knowledge of HIV and low media exposure.

Conclusion

The HIV testing coverage among AYA in Nigeria is well below the national target of 95% indicated in the national HIV/AIDS strategic framework (2017–2021). Also, the low rate of HIV testing found in this study means realising the UNAIDS first 95 will require interventions targeting AYA. These interventions should focus on improving young people's knowledge of HIV, reducing negative stigma belief through media campaigns and increasing access to HIV testing through home-based testing and "opt-out" strategy at the point of care.

Educational attainment and HIV testing and counselling service utilisation during antenatal care in Ghana: Analysis of Demographic and Health Surveys

Introduction

Receiving results for Human Immunodeficiency Virus (HIV) testing and counselling during antenatal care (ANC) is critical for eliminating mother-to-child transmission. We investigated the educational attainment of women and receiving results for HIV testing and counselling (HTC) during ANC in Ghana.

Materials and methods

We extracted data from the women’s files of the 2008 and 2014 Ghana Demographic and Health Surveys. The study sampled 2,660 women aged 15–49 with complete data on receiving HIV testing results during ANC. We computed the highest educational attainment and receipt of HTC results for each of the surveys and presented it with a dot plot. Two Binary Logistic Regression Models were fitted to determine the likelihood of receiving HTC results by the educational attainment of the women.

Results

We found that receiving HTC results was highest among women with secondary or higher education (87.4% in 2008 and 89.5% in 2014) and least among those with no education (69.9% in 2008 and 76.8 in 2014). From the regression analysis, women with secondary or higher level of education [AOR = 1.535; CI = 1.044, 2.258], richest women [AOR = 5.565; CI = 2.560, 12.10], and women aged 30–34 years [AOR = 1.693; CI = 1.171, 2.952], were more likely to receive HTC results. However, those who did not know that a healthy-looking person can have HIV or not [AOR = 0.322; CI = 0.161, 0.646] were less likely to receive HTC results.

Conclusion

Despite the relatively high receipt of HTC results at ANC observed between 2008 and 2014, our findings revealed disparities driven by educational attainment, wealth status, age, ANC visits and residence. This indicates that women with no education, those from rural areas, younger and poor women are missing out on the full continuum of HTC service at ANC. The Health Promotion Unit of Ghana Health Service through Community Health Nurses and the Community-Based Health Planning and Services, should intensify their education programs on HIV and make full utilisation of HIV testing and counselling service appealing to women during ANC. This is particularly to be prioritised among the least educated, younger women and rural dwellers.
