RESUMEN
Oral pre-exposure prophylaxis (PrEP) is a critical intervention for HIV prevention among key populations (KP) in Nigeria. However, little is known about its coverage among adolescent and young key populations (AYKP). Using the 2020 Integrated Biological & Behavioural Surveillance Survey conducted among KP, including female sex workers (FSW), men who have sex with men (MSM), people who inject drugs (PWID), and transgender people (TG), we assessed the awareness and uptake of PrEP among AYKP (15-24 years) in Nigeria. We performed weighted descriptive statistics and logistic regression analyses. Of the 6882 AYKP included in this study, 36.1% were aware of PrEP, ranging from 47.9% in MSM to 19.8% in FSW. Compared with FSW, MSM (aOR = 3.7, 95%CI = 3.22-4.35) and TG (aOR = 2.6, 95%CI = 2.18-2.98) had significant higher odds of PrEP awareness. Among those aware of PrEP, 24.5% had ever taken PrEP. The uptake of PrEP varied by KP group: TG (28.1%), MSM (25.3%), PWID (18.0%), and FSW (14.4%). MSM (aOR = 2.6, 95%CI = 1.72-4.07) and TG (aOR = 2.7, 95%CI = 1.71-4.14) had significant higher odds of PrEP uptake relative to FSW. The awareness and uptake of PrEP among AYKP in Nigeria is low. This calls for more awareness creation about PrEP addressing the barriers that limit its uptake.

Self-administered HIV testing may be a promising strategy to improve testing in hard-to-reach young adults, provided they are aware of and willing to use oral HIV self-testing (HIVST). This study examined awareness of and willingness to use oral HIVST among 350 high-risk young adults, aged 18-22, living in Kenya's informal urban settlements. Bivariate and multivariate logistic regressions were used to examine differences in HIVST awareness and willingness by demographic and sexual risk factors. Findings showed that most participants were male (56%) and less than 20 years old (60%). Awareness of oral HIVST was low (19%). However, most participants (75%) were willing to use an oral HIV self-test in the future and ask their sex partner(s) to self-test before having sex (77%). Women (OR = 1.80, 95%CI:1.11, 2.92), older participants (aged 20+) (OR = 2.57, 95% CI:1.48, 4.46), and more educated participants (OR = 2.25, 95%CI:1.36, 3.70) were more willing to use HIVST as compared to men, teen-aged, and less educated participants, respectively. Young adults who reported recent engagement in high-risk sexual behaviors, such as unprotected sex, sex while high or drunk, or sex exchange, were significantly less likely to be willing to use an oral HIV self-test kit (OR = 0.34, 95%CI:0.13,0.86). Those with the highest monthly income (OR = 0.47, 95%CI: 0.25, 0.89) were also less willing to use HIVST. More community- and peer-based efforts are needed to highlight the range of benefits of HIVST (i.e., social, clinical, and structural) to appeal to various youth demographics, in addition to addressing concerns relating to HIVST.

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.

Identifying the geographic hotspots of HIV infection among high-risk populations such as transgender people is critical to ending the HIV epidemic in the United States (U.S.). This study examined the spatial pattern of HIV positivity rate and the associated correlates among transgender persons in the 48 contiguous states and the District of Columbia in the U.S. The data source was the 2015 U.S. Transgender Survey (n = 27,715). We conducted spatial analyses, with state as the unit of analysis. We fitted a spatial lag regression model to assess demographic, social, and behavioral risk variables associated with HIV. The HIV positivity rate ranged by state from 0.5% to 17.1%, with a mean of 2.9%. There was a significant positive global spatial autocorrelation (global Moran's I = 0.42, p = 0.001). The identified spatial clusters of high values (hot spots i.e., states with high HIV positivity rates surrounded by states with similarly high rates) included five neighboring states (Arkansas, Louisiana, Mississippi, Alabama, and Tennessee) in the Southern region. HIV positivity rate was positively associated with the percentage of transgender persons who were non-Hispanic Black, had no high school education, living in poverty, and engaged in sex work. Structural interventions are needed to address education, poverty, racial discrimination, and sex work that predispose transgender persons to HIV.

BACKGROUND: There is an increasing demand for family planning to limit childbearing in sub-Saharan Africa (SSA). However, limited studies have quantified the spatial variations. This study examined: (i) the spatial patterns in the demand for family planning to limit childbearing and satisfied with modern methods, and (ii) the correlates of the demand for family planning to limit childbearing satisfied with modern methods in SSA. METHODS: This study analyzed secondary data on 306,080 married/in-union women obtained from Demographic Health Surveys conducted between 2010 and 2019 in 33 sub-Saharan African countries. We conducted exploratory spatial data analysis, with countries as the unit of analysis. We also performed regression analysis to determine the factors associated with demand for family planning to limit childbearing satisfied with modern methods in SSA. RESULTS: The mean percentage of women who demanded for family planning to limit childbearing by country was 20.5% while the mean prevalence of demand for family planning to limit childbearing satisfied with modern methods by country was 46.5%. There was a significant positive global spatial autocorrelation in the demand for family planning to limit childbearing (global Moran's I = 0.3, p = 0.001). The cluster map showed the concentration of cold spots (low-low clusters) in western and central Africa (WCA), while hot spots (high-high clusters) were concentrated in eastern and southern Africa (ESA). Also, the demand for family planning to limit childbearing satisfied with modern methods showed significant positive global spatial autocorrelation (global Moran's I = 0.2, p = 0.004) and concentration of cold spots in WCA. In the final multivariable regression model the joint family planning decision making (ß = 0.34, p < 0.001), and antenatal care (ß = 13.98, p < 0.001) were the significant factors associated with the demand for family planning to limit childbearing satisfied by modern methods. CONCLUSIONS: There are significant spatial variations in the demand for family planning to limit childbearing and the demand satisfied by modern methods, with cold spots concentrated in WCA. Promoting joint decision making by partners and increasing uptake of antenatal care may improve the demand for family planning to limit childbearing satisfied with modern methods.
In sub-Saharan Africa (SSA), studies have shown that the proportion of married women who want to stop having children has been increasing as well as the proportion using modern contraceptive methods among them. These studies also indicated that this proportion of women are higher in certain regions of Africa than the others. To extend these previous findings, we performed geographical analysis to assess how the proportion of married/in-union women who want to stop having children and the ones using modern methods among them differ geographically. Our findings indicated that neighboring countries where the proportion of married/in-union women who want to stop having children was higher than the overall average were concentrated in eastern and southern Africa (ESA), while neighboring countries in which the proportion of married/in-union women who want to stop having children was lower than the overall average were concentrated in western and central Africa (WCA). Similarly, the results also showed that neighboring countries where the proportion of married/in-union women using modern contraceptive methods among those who want to stop having children was lower than the overall average were concentrated in WCA. Our findings suggest that increasing joint decision making on family planning and uptake of antenatal care in SSA may improve the use of modern contraceptive methods among married/in-union women who want to stop childbearing.

OBJECTIVE: To assess the percentage of the demand for family planning to limit childbearing satisfied with female permanent contraception (FPC) in sub-Saharan Africa (SSA) and the disparities by sociodemographic characteristics (educational status, wealth, religion, and area of residence). STUDY DESIGN: This study was a secondary data analysis of Demographic and Health Surveys conducted in SSA. Countries with a standard DHS conducted between 2010 and 2019 were eligible for inclusion. We performed a meta-analysis with a random-effects model to estimate the percentage of the demand for family planning to limit childbearing satisfied with FPC and differences by sociodemographic characteristics. RESULTS: Demographic and Health Surveys (2010-2018) of 33 countries, with a total of 67,476 women with a demand for family planning to limit childbearing were included in this study. The pooled percentage of the demand for family planning to limit childbearing satisfied with FPC was 4.13% (95%CI = 2.43-6.23%, I = 99.36%, p = 0.001). The percentage ranged from 0.26% (95%CI = 0.10-0.67) in Angola to 26.85% (95%CI = 25.86-27.85%) in Malawi. The demand for family planning to limit childbearing satisfied with FPC was significantly higher in women from rich households (PR = 1.41, 95%CI = 1.21-1.65, p < 0.001). However, the differences by educational status, religion, or area of residence were not statistically significant. CONCLUSIONS: The uptake of FPC among women with a demand for family planning to limit childbearing is low in many countries in SSA. Multilevel interventions are needed to address the barriers that may be limiting informed and voluntary uptake of FPC in SSA.

In the era of highly active antiretroviral therapy (HAART), obesity is increasingly being reported among people living with HIV (PLHIV). In this study, we reviewed published literature on body mass index (BMI) changes among treatment-naïve adult PLHIV who started HAART and remained on treatment for at least six months. Using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline, four databases were searched, and results of included studies were synthesized to describe the BMI trend among PLHIV on treatment. The search generated 4948 studies, of which 30 were included in the qualitative synthesis and 18 were eligible for the meta-analysis. All the studies showed an increase in group BMI. HAART was associated with increase in BMI (pooled effect size [ES] = 1.58â kg/m2; 95% CI: 1.36, 1.81). The heterogeneity among the 18 studies was high (I2 = 85%; p < .01). Subgroup analyses showed pooled ES of 1.54â kg/m2 (95% CI: 1.21, 1.87) and 1.63â kg/m2 (95% CI: 1.34, 1.91) for studies with follow-up ≤1 year and >1 year, respectively. We conclude that the greatest gain in BMI is in the initial 6-12 months on treatment, with minor gains in the second and subsequent years of treatment.

Despite global calls for stronger linkages between family planning and HIV, a growing body of evidence in sub-Saharan Africa suggests that the integration of family planning and HIV service delivery is suboptimal in some countries. In this study, we assess the integration and quality of family planning services in health facilities that provide HIV-related services in Nigeria. This study analysed secondary data from the Performance Monitoring and Accountability 2020 cross-sectional survey conducted between May and July 2016 in seven states in Nigeria. Our study sample was restricted to 290 health facilities providing HIV services. We performed descriptive statistics and binary logistic regression analyses. Ninety-five per cent of the health facilities reported offering family planning counselling, provision of family planning methods, and/or referral for family planning methods to clients accessing HIV services. About 84% of these health facilities with integrated family planning and HIV services reported that they discussed the preferred method, dual methods, instructions and side effects of the chosen method, and the reproductive intentions with clients during an HIV consultation. None of the health facilities' characteristics was significantly associated with the integration of family planning services into HIV services. Private health facilities (aOR 0.3, 95% CI 0.07-0.92), urban health facilities (aOR 3.8, 95% CI 1.64-8.76), and provision of postnatal care (aOR 3.9, 95% CI 1.10-13.74) were statistically associated with the quality of family planning services provided to clients accessing HIV services. Family planning services were integrated into HIV services in a majority of the health facilities in our study. However, our findings indicate the need for improvement in the quality of family planning services provided to clients accessing HIV services.

BACKGROUND: There has been a global rise in interest and efforts to improve under-five mortality rates, especially in low- and middle-income countries. Ghana has made some progress in improving this outcome; however, the extent of such progress and its equity implications remains understudied. METHODS: This study used a joinpoint regression analysis to assess the significance of changes in trends of under-five mortality rates in Ghana between 1988 and 2017 using data from seven rounds of the Ghana Demographic and Health Survey. Annual percentage change (APC) was estimated. The APCs of different dimensions of equity (residence, administrative region, maternal education and wealth quintile) were compared by coincidence test - to determine similarity in joinpoint regression functions via 10 000 Monte Carlo resampling. RESULTS: There has been progress in reduction of under-five mortality in Ghana between 1988 and 2017 with an annual percentage change of -3.49%. Disaggregation of the trends showed that the most rapid improvement in under-five mortality rates occurred in the Upper East Region (APC = -5.0%). The closing of under-five mortality equity gaps in the study period has been uneven in the country. The gap between rural and urban rates has closed the most, followed by regional gaps (between Upper East and Ashanti Region), while the most persistent gaps remain in maternal education and wealth quintile. CONCLUSION: The findings suggest that programmatic interventions have been more successful in reducing geographic (rural-urban and by administrative region) than non-geographic (maternal education and wealth quintile) inequities in under-five mortality in Ghana. To accelerate reduction and bridge the inequities in under-five mortality, Ghana may need to pursue more social policies aimed at redistribution.
CONTEXTE: Il y a eu une augmentation mondiale de l'intérêt et des efforts pour améliorer les taux de mortalité des moins de cinq ans, en particulier dans les pays à revenu faible et intermédiaire. Le Ghana a fait quelques progrès dans l'amélioration de ce résultat; cependant, l'ampleur de ces progrès et ses implications en termes d'équité restent sous-étudiées. MÉTHODES: Cette étude a utilisé une analyse de régression à point de jonction pour évaluer l'importance des changements dans les tendances des taux de mortalité des moins de cinq ans au Ghana entre 1988 et 2017 en utilisant les données de sept cycles de l'enquête démographique et de santé du Ghana. La variation annuelle en pourcentage (VAP) a été estimée. Les VAP des différentes dimensions d'équité (résidence, région administrative, éducation de la mère et quintile de richesse) ont été comparées par test de coïncidence, pour déterminer la similarité des fonctions de régression à point de jonction via 10000 rééchantillonnage de Monte Carlo. RÉSULTATS: Des progrès ont été atteints dans la réduction de la mortalité des moins de cinq ans au Ghana entre 1988 et 2017 avec une VAP de -3,49%. La désagrégation des tendances a montré que l'amélioration la plus rapide des taux de mortalité des moins de cinq ans s'est produite dans la région du Haut-Est (VAP = -5,0%). La réduction des écarts d'équité en matière de mortalité des moins de cinq ans au cours de la période d'étude a été inégale dans le pays. L'écart entre les taux ruraux et urbains s'est le plus resserré, suivi des écarts régionaux (entre le Haut-Est et la région Ashanti), tandis que les écarts les plus persistants restent dans l'éducation des mères et le quintile de richesse. CONCLUSION: Les résultats suggèrent que les interventions programmatiques ont mieux réussi à réduire les inégalités géographiques (rurales-urbaines et par région administrative) que les inégalités non géographiques (éducation des mères et quintile de richesse) dans la mortalité des moins de cinq ans au Ghana. Pour accélérer la réduction et combler les inégalités en matière de mortalité des moins de cinq ans, le Ghana pourrait avoir besoin de poursuivre davantage de politiques sociales visant à la redistribution.

HIV testing among men is critical to ending the HIV epidemic in sub-Saharan Africa. Using the Multiple Indicator Cluster Survey, 2016/2017, we examined the uptake and determinants of HIV testing among sexually active men in Nigeria. A total of 1254 young people (15-24 years) and 7866 adults (25-49 years) were included in the analysis. We conducted binary logistic regression analyses to estimate the odds ratio (OR) and adjusted OR for testing for HIV in the last 12 months preceding the survey. Approximately 18.7% of men had tested for HIV (young people [17%] vs. adult [19%], p=0.125). The overall adjusted model showed that the likelihood of HIV testing was significantly higher among those with at least primary education, currently married, who used condom at last sexual intercourse, who drank alcohol one month preceding the survey, with no discriminatory attitudes towards people living with HIV (PLHIV), exposed to media, in the rich and richest quintiles, and in the North Central Zone. Education, geopolitical zone, and discriminatory attitudes towards PLHIV were the significant factors common to both age groups. Our results suggest that HIV testing among sexually active men in Nigeria is low, and the determinants vary between young people and adults.

Despite the effectiveness of antiretroviral therapy (ART) in the prevention of mother-to-child transmission of HIV (PMTCT), some HIV-infected women in PMTCT care are at risk of transmitting HIV to their babies. Using a 1:1 unmatched case-control study design, we assessed the risk factors for perinatal transmission among women who received ART for PMTCT in Sokoto State, Nigeria. Data were abstracted from medical records of cases (94 HIV-infected babies) and controls (94 HIV-uninfected babies) and their mothers who accessed PMTCT services in three purposefully selected secondary health facilities. We conducted univariate and multivariate logistic regressions to determine if sociodemographic characteristics, time of enrolment, type of maternal ART, receipt of infant antiretroviral (ARV) prophylaxis, place of delivery, or feeding practice were associated with HIV infection among HIV-exposed babies. Sixteen percent of the mothers of babies in the case group had early enrolment while 90% of those in the control group enrolled early. Infant prophylaxis was received in 54% of cases and 95% of controls. In both groups, 99% of the mothers practiced mixed feeding. In the univariate analysis, factors that were significantly associated with HIV infection were religion (islam), rural residence, lateâ enrolment, and non-receipt of infant ARV prophylaxis. In the multivariate analysis, rural residence (Adjusted odds ratio (aOR) = 8.01, 95% CI = 1.79-35.78), late enrolment (aOR = 41.72, 95% CI = 15.16-114.79), and non-receipt of infant ARV prophylaxis (aOR = 4.1, 95% CI = 1.18-14.33) remained statistically significant. Findings from this study indicate that eliminating MTCT in Nigeria requires interventions that will enhance timely access of ART by mother-baby dyads.

Antiretroviral (ARV) drugs are effective in the prevention of mother-to-child transmission of HIV (PMTCT), however many sub-Saharan African countries are yet to achieve universal ARV coverage among pregnant women living with HIV. This study examined factors associated with ARV coverage for PMTCT in 41 sub-Saharan Africa countries. Country-level aggregated data were obtained from the Joint United Nations Programme on HIV/AIDS, World Health Organization, and United Nations Children's Fund. Using Spearman's rho and point-biserial correlation, we conducted bivariate analyses between ARV coverage for PMTCT and the following variables: stigma, antenatal care (ANC) uptake, institutional delivery, community delivery of ARV drugs, number of HIV testing and counselling (HTC) facilities, and density of skilled health workers. We also performed a multivariate median regression with the significant correlates. P < .05 was considered statistically significant for all the tests. The median ARV coverage for PMTCT was 76% (IQR: 55-85%). ARV coverage for PMTCT was significantly associated with HTC facilities (r = 0.46, p = .004), institutional delivery (r = 0.48, p = .002), ANC uptake: at least one visit (r = 0.54, p = .001), and stigma (r=-0.52, p = .003). In the multivariate analysis, only stigma remained statistically significant (ß = -0.6, 95% CI = -1.13, -0.07, p = .03). To eliminate perinatal transmission of HIV in sub-Saharan Africa, interventions that will address stigma-related barriers to uptake of PMTCT services are needed. More research on country-specific population-level correlates of ARV coverage for PMTCT is recommended.

BACKGROUND: Congenital syphilis is a global health problem, yet it has received little attention in recent years. Despite cost-effective syphilis screening and treatment, it continues to contribute hugely to perinatal morbidity and mortality worldwide. AIMS: To determine the prevalence and treatment coverage trend for syphilis among pregnant women in the national prevention of mother-to-child transmission programme in Nigeria and to evaluate progress towards the elimination of congenital syphilis in the country. METHODS: A retrospective analysis of validated national health sector performance data on pregnant women attending antenatal care at prevention of mother-to-child transmission clinics from 2013 to 2016 in Nigeria. RESULTS: The proportion of new antenatal care attendees who annually received serological testing for syphilis increased from 12.2% in 2013 to 16.3% in 2016 (p-trend<0.0001). Although the prevalence of maternal syphilis decreased from 3.2% in 2013 to 1.4% in 2016 (p-trend<0.0001), the syphilis treatment coverage during pregnancy has decreased from 71.3% in 2013 to 54.9% in 2016 (p-trend<0.0001). CONCLUSIONS: Maternal syphilis screening and treatment in Nigeria are inadequate to meet the elimination aspirations. A rapid scale-up of antenatal care syphilis screening and treatment are crucial to averting an epidemic in Nigeria by 2020.

BACKGROUND: Hepatitis B virus (HBV) infection in Africa is mostly acquired before the age of 5 years through vertical or horizontal routes. While all the countries in the World Health Organization African region have introduced HBV vaccination into their national immunization programs, the rate of protective immune response to HBV vaccine among children in Africa has not been systematically synthesized. In this study, we estimated the HBV vaccine seroprotection rate (defined as anti-HBs titer ≥ 10 IU/L) and the associated factors among under-five children who completed a primary series of HBV vaccination in Africa. METHODS: We systematically searched PubMed, Web Science, and Scopus databases from inception to May 2022 for potentially eligible studies. The pooled seroprotection rate was estimated using a random-effects model with Freeman-Tukey double arcsine transformation and the associated factors were examined using odds ratio estimated by the DerSimonian and Laird method. RESULTS: From the 1063 records identified, 29 studies with a total sample size of 9167 under-five children were included in the meta-analysis. The pooled seroprotection rate was 89.23% (95% CI 85.68-92.33%, I2 = 95.96%, p < 0.001). In the subgroup analyses, there was a significant difference in the rate by the assay method, vaccine dose, and vaccine combination. HIV-positive children had lower odds of achieving seroprotection when compared with HIV-negative children (OR = 0.22, 95%CI 0.12-0.40). CONCLUSIONS: The majority of under-five children in Africa achieved seroprotection after completing three or four doses of HBV vaccine. However, the rate was lower among children living with HIV. This calls for interventions to timely identify and address nonresponse to HBV vaccine, particularly among immunosuppressed children.
RESUMEN
BACKGROUND: Young key populations (YKP) contribute to the burden of HIV in Nigeria and are a priority population for oral pre-exposure prophylaxis (PrEP). However, their uptake of PrEP remains low. We assessed the main barriers to PrEP uptake and the variation among YKP (15-24 years) in Nigeria. METHODS: This study was a secondary data analysis of the 2020 Integrated Biological & Behavioural Surveillance Survey conducted among key populations (KP), including female sex workers (FSW), men who have sex with men (MSM), people who inject drugs (PWID), and transgender people (TG), in 12 states in Nigeria. A closed-ended question asking the main reason for not taking PrEP among KP who had never taken PrEP was included in the surveillance questionnaire. We collapsed the responses into six barrier themes. Using multinomial logistic regression analysis, we examined the association between the barriers (dependent variable) and KP group (independent variable), controlling for age, educational attainment, religion, marital status, employment status, and geopolitical zone. RESULTS: A total of 1776 YKP were included in this study. The most cited barriers by KP group were: lack of access (28.3%) and fear of side effects (28.3%) by FSW; lack of interest (37.1%) by MSM; low risk perception (65.5%) by PWID; and lack of access (34.4%) by TG. The odds of reporting fear of side effects, lack of access, lack of interest, and nonspecific/others reasons were significantly different by KP group. CONCLUSIONS: The barriers limiting the uptake of PrEP among YKP vary by KP group. Our results highlight the need for KP-specific interventions to improve the uptake of PrEP among YKP in Nigeria.

BACKGROUND: Despite the increased risk of cervical cancer (CC) among women living with HIV (WLHIV), CC screening and treatment (CCST) rates remain low in Africa. The integration of CCST services into established HIV programs in Africa can improve CC prevention and control. However, the paucity of evidence on effective implementation strategies (IS) has limited the success of integration in many countries. In this study, we seek to identify effective IS to enhance the integration of CCST services into existing HIV programs in Nigeria. METHODS: Our proposed study has formative and experimental activities across the four phases of the Exploration, Preparation, Implementation, and Sustainment (EPIS) framework. Through an implementation mapping conducted with stakeholders in the exploration phase, we identified a core package of IS (Core) and an enhanced package of IS (Core+) mostly selected from the Expert Recommendations for Implementing Change. In the preparation phase, we refined and tailored the Core and Core+ IS with the implementation resource teams for local appropriateness. In the implementation phase, we will conduct a cluster-randomized hybrid type III trial to assess the comparative effectiveness of Core versus Core+. HIV comprehensive treatment sites (k = 12) will be matched by region and randomized to Core or Core+ in the ratio of 1:1 stratified by region. In the sustainment phase, we will assess the sustainment of CCST at each site. The study outcomes will be assessed using RE-AIM: reach (screening rate), adoption (uptake of IS by study sites), IS fidelity (degree to which the IS occurred according to protocol), clinical intervention fidelity (delivery of CC screening, onsite treatment, and referral according to protocol), clinical effectiveness (posttreatment screen negative), and sustainment (continued integrated CCST service delivery). Additionally, we will descriptively explore potential mechanisms, including organizational readiness, implementation climate, CCST self-efficacy, and implementation intentions. DISCUSSION: The assessment of IS to increase CCST rates is consistent with the global plan of eliminating CC as a public health threat by 2030. Our study will identify a set of evidence-based IS for low-income settings to integrate evidence-based CCST interventions into routine HIV care in order to improve the health and life expectancy of WLHIV.

BACKGROUND: Amid the dwindling donor support for HIV in Nigeria, there is an urgent need for additional domestic HIV funding. This study estimates the required financial resources for people living with HIV (PLHIV) and the potential magnitude of domestic resources for HIV through the National Health Insurance Scheme (NHIS) and by prioritizing HIV within the health budget. METHODS: We estimated the resource needs for providing antiretroviral therapy (ART) to adults, children, and pregnant women living with HIV under 3 scenarios: current coverage rates, coverage rates based on historical trends, and a rapid scale-up situation. We conducted a fiscal space analysis to estimate the potential contribution from macroeconomic growth, the NHIS, and prioritizing HIV within the health budget from 2020 to 2025. RESULTS: At current coverage rates, the annual treatment costs for adults would range between US$ 505 million in 2020 to US$ 655 million in 2025; for children, it ranges from US$ 33.5 million in 2020 to US$ 32 million in 2025. The annual costs of providing PMTCT at current coverage rates range from US$ 65 million in 2020 to US$ 72 million in 2025. An additional US$ 319 million could potentially be generated between 2020 and 2025 through the NHIS for HIV. Prioritizing HIV within the health budget can generate an additional US$ 686 million. CONCLUSION: Substantial domestic funds can be mobilized by these means to sustain the HIV response. However, because this additional funding may not be sufficient to cover all PLHIV, a phased approach, initially prioritizing certain populations such as children or pregnant women, is recommended.

BACKGROUND: Hepatitis B virus (HBV) screening is an important component of antenatal care for pregnant women in Nigeria. However, the screening rates remain low, particularly at primary healthcare centers (PHCs). The objective of this study was to identify the barriers affecting antenatal HBV screening in PHCs in Nigeria from the perspective of health workers. METHODS: We conducted a survey among 30 health workers from 30 PHCs (one per PHC) across three states (Akwa Ibom, Anambra, and Kaduna) in Nigeria. An open-ended questionnaire was used to obtain written responses on the perceived barriers limiting antenatal HBV screening in PHCs and their recommended solutions to the identified barriers. The data were analyzed using an inductive thematic approach. RESULTS: The perceived barriers exist at patient, provider and health system levels. They included: lack of test kits, unaffordability of HBV test, shortage of trained personnel, poor awareness among pregnant women, knowledge of HBV among health workers, high cost of antiviral treatment, and unavailability of HBV vaccine. The recommended solutions to the identified barriers were: making test kits and vaccines available and free, creating awareness about HBV, and capacity-building interventions for health workers. CONCLUSIONS: HBV screening of pregnant women attending PHCs in Nigeria appears to be affected by multilevel barriers. As the country continues to work towards eliminating HBV, these highlighted barriers at the patient, provider and health system levels must be addressed through effective and sustainable interventions.

Measles remains an important cause of childhood mortality in many resource-limited countries. With Sustainable Development Goals (SDG), there has been increasing emphasis on measles vaccination as a key strategy to remarkably improve child survival. While progress has been made towards measles vaccination coverage due to SDG in some settings, there has been no prior study evaluating its impact in Nigeria. To assess the effectiveness of SDG policy implementation on measles vaccination coverage, we examined the changes in first dose of measles vaccination coverage rates among children aged 9-15 months following the implementation of SDG, and changes in spatial patterns of measles vaccination from 2014 to 2019 in Ekiti State, Southwest Nigeria. Using state and local government area-level District Health Information data from January 2014 to December 2019, we conducted interrupted time series (ITS) and spatiotemporal analyses. The ITS evaluated the immediate and continuous effects of SDG policy implementation on the monthly childhood measles vaccination coverage by comparing longitudinal changes in rates between pre-intervention period (January 2014-December 2015) and during-intervention period (January 2016-December 2019). The low and high coverage clusters across the years were detected with spatial cluster analysis. The average state-level measles vaccination coverage rates from 2014 to 2019 was 70.67%. In 2019, coverage rate was 49%-a 35.53% decline from 76% in 2014 and a state-level gap of 46%. The geographical distribution of measles vaccination varied considerably across the local government areas from 2014 to 2019. There was an initial acceleration of vaccination rates (ß^ = 24.07, p-value = 0.012), but a significant decrease in coverage rates after implementation of SDG policy in Ekiti State (ß^ = -1.08, p-value < 0.001). No local government area had accelerated monthly coverage rates following SDG-implementation. Evidence suggests immediate acceleration in coverage rates which could not be sustained during SDG-era and calls for a rethink measles immunization coverage strategy in the state and other resource-limited jurisdictions to ensure vaccination scale-up.
