Purpose: To determine sex differences in the prevalence of oral and anal high-risk HPV infections among heterosexually active males and females in Ibadan.

Methods: This was a secondary analysis from the Sexual Behavior and HPV Infections in Nigerians in Ibadan (SHINI) study that involved sexually active males and females aged 18-45 years. After a face-to-face interview, samples were collected from the mouth, cervix, vulva, and anus by a sex-matched trained nurse.

Recruitment and Retention for Alzheimer's Disease Diversity Genetic Cohorts in the ADSP (READD-ADSP): A global effort to identify genetic factors in Alzheimer's disease.

Introduction: Alzheimer's disease (AD) remains a major neurocognitive disorder of global health significance. Globalizing ancestral diversity in AD genetics is essential to identify causal variants, improve diagnosis, and enable equitable therapeutic interventions across populations. The Recruitment and Retention for Alzheimer's Disease Diversity Genetic Cohorts in the ADSP (READD-ADSP) initiative addresses this by including African ancestry and Hispanic/Latinx (HL) ancestry populations.

ABCA7 deletion lowers age at onset of Alzheimer's disease and interacts with APOE ε4 synergistically in African-ancestry populations.

Introduction: Apolipoprotein E (APOE) and ABCA7 genes are among the strongest heritable risk factors for Alzheimer's disease (AD) in African-ancestry (AA) populations. APOE 𝜀4 affects both risk and age at onset (AAO), with lower risk in AA populations. This study evaluates the independent and interactive effects of the AA-specific ABCA7 frameshift deletion and APOE 𝜀4 allele on AAO.

Background: Inflammation might predispose to worse outcomes after an ischemic stroke. This has not been characterized among indigenous Africans.

Purpose: We investigated the association between inflammatory biomarkers, stroke severity, and outcomes in Africans.

Developing biobanking processes for Alzheimer's disease and related dementia research in Africa: Experience from the Recruitment and Retention for Alzheimer's Disease Diversity in the Alzheimer's Disease Sequencing Project (READD-ADSP).

The Recruitment and Retention for Alzheimer's Disease Diversity in the Alzheimer's Disease Sequencing Project (READD-ADSP) aims to recruit 5000 African participants (Alzheimer's disease [AD] and cognitively unimpaired controls) to generate genomic and biomarker data to better characterize AD neurobiology in Africa from countries that constitute the African Dementia Consortium (AfDC). Blood samples from study participants are separated into fractions and transported to the African Coordinating Centre (ACC: Ibadan, Nigeria), where DNA extraction and long-term biospecimen storage are carried out. Plasma and DNA aliquots are shipped to the John P.

Growing Data science Research in Africa to Stimulate Progress (GRASP) program: Rationale and overview.

Brain health is pivotal to achieving overall health and all current sustainable development goals (SDGs). However, a dedicated training program in brain health research to unravel its complex determinants, especially genetic, sociodemographic and lifestyle factors is lacking in Africa. The rowing Data-science esearch in frica to timulate rogress () is a three-year program designed to harness innovation potential to build sustainable data science (DS) research capacity among qualified African scholars through innovative partnerships and collaborations.

Antecedent sedative use is independently associated with stroke occurrence among west Africans: Evidence from the SIREN case-control study.

Background: Several factors have been independently associated with stroke occurrence globally. However, the association between sedative use and stroke risk is yet to be established in West Africa.

Objective: To assess the association between sedatives and stroke among West Africans.

Communicating the ethical, legal, and social issues in neurobiobanking and stroke genomic research in Africa: Project intervention tools development and evaluation procedures.

Background And Aim: Issues concerning appropriate Community Engagement (CE) and communication of research outcomes with stakeholders have received the attention of scholars in different sub-fields of clinical research. However, given its novel nature, especially in Sub-Saharan Africa, CE addressing the ethical, legal, and social implications (ELSI) of neurobiobanking and stroke genomic research has not received much scholarly attention. Therefore, this study was designed as a pioneering effort to report the procedures for developing and evaluating intervention tools for the CE component of the African Neurobiobank for Precision Stroke Medicine ELSI Project.

Low vegetable consumption doubles the odds of stroke among people with hypertension: Findings from the SIREN Study in West Africa.

Background: While hypertension is a primary risk factor for higher stroke risk, adequate vegetable consumption has been linked with a lower odds of stroke. However, it is unclear whether low/inadequate vegetable consumption could aggravate the odds of stroke among people with hypertension. This study assessed the interaction of low vegetable consumption and hypertension with stroke among West Africans.

Low-density lipoprotein cholesterol and severity of intracerebral hemorrhage: Insights from the SIREN study.

Background: We investigated the link between LDL-C and markers of ICH severity among Indigenous West Africans in the Stroke Investigative Research and Education Network study.

Methods: ICH severity was evaluated using the Glasgow Coma Scale (GCS), Stroke Levity Scale (SLS), and the National Institutes of Health Stroke Scale (NIHSS). The serum LDL-c of the study population was dichotomized into <133 mg/dl and ≥ 133 mg/dl using the optimum threshold by the Youden Index after assessing the linear relationship between the serum LDL-c measured at admission and ICH severity markers.

Understanding the Gendered Impact of COVID-19 on Young Self-Employed Nigerian Women and Coproducing Interventions That Foster Better Systems and Well-Being: Protocol for a Multimethods Study.

Background: The COVID-19 pandemic has had disproportionate economic and health impacts on self-employed workers in Nigeria, particularly self-employed women and youth. Though uniquely different, the COVID-19 pandemic shares similarities with events such as childbirth, family, and health emergencies. Self-employed young women lack adequate support structures to cope with disruptive life events, which have negative consequences for their well-being.

Research participants' perception of ethical issues in stroke genomics and neurobiobanking research in Africa.

Background: There is a growing interest in stroke genomics and neurobiobanking research in Africa. These raise several ethical issues, such as consent, re-use, data sharing, storage, and incidental result of biological samples. Despite the availability of ethical guidelines developed for research in Africa, there is paucity of information on how the research participants' perspectives could guide the research community on ethical issues in stroke genomics and neurobiobanking research.

A mixed-methods study of the drivers of stunting reduction among children under five in Nigeria, 2008-2018.

Background: Although stunting reduction at the national level in Nigeria has been modest in recent decades, especially considering the country's rapid economic growth, there is much subnational variation.

Objectives: The objective of this study was to identify the factors associated with declining stunting prevalence in those states in Nigeria where the most progress was made between 2008 and 2018.

Methods: This mixed-methods study included quantitative analysis of household survey data using regression-based Oaxaca-Blinder decomposition analysis to identify factors associated with a change in mean height-for-age z-score (HAZ) over time; deductive thematic analysis of qualitative data collected through key informant interviews and focus group discussions; and policy and program review.

Social capital, functional health status and quality of life among adults in rural Southwest Nigeria.

Background: The health and well-being of adults is important for attainment of the third sustainable development goal. Both social capital and health are essential for development, hence research is needed to explore this relationship in low income countries. Therefore, this study explored the association(s) between structural social capital, functional health status, and quality of life among adults in rural southwest Nigeria.

Modelling of childbearing progression among women living with HIV in Ibadan, Nigeria.

Background: Childbearing is a major concern for women living with HIV especially in low-middle income countries. There are fears about access to care, risk of vertical transmission, health challenges, maternal and child morbidity/mortality. Investigation of childbearing progression and its associated factors among these women will be useful for design of reproductive healthcare services of these women and ultimately address their multifaceted concerns.

Gender disparities in hypertension prevalence, awareness and healthcare seeking behaviour among young adults in Nigeria.

Background: The burden of hypertension and healthcare seeking behaviour can be driven by gender-related inequalities in access to care. Low hypertension awareness often originates in early adulthood, determining gender patterns in hypertension. The factors that contribute to these patterns in this life stage are critical for improving hypertension control and reducing cardiovascular disease risk.

Geo-demographic and socioeconomic determinants of diagnosed hypertension among urban dwellers in Ibadan, Nigeria: a community-based study.

Background: The relationship between diagnosed high blood pressure (HBP) and proximity to health facilities and noise sources is poorly understood. We investigated the associations between the number of persons diagnosed with HBP at different distance corridors of noise-generating sources (churches, mosques, bus stops, and road networks), and blood pressure monitoring outlets (healthcare facilities and pharmaceutical shops) in Ibadan, Nigeria. In addition, we investigated the likelihood of being diagnosed with HBP using distance from noise-generating sources, distance to blood pressure monitoring outlets, socio-demographic and clinical status of the participants.

Co-creation and application of a framework for the de-prioritization of urban communities during insecticide-treated bed net mass campaigns for malaria prevention and control in Kwara State, Nigeria.

Background: Malaria continues to be a major cause of illness and death worldwide, particularly affecting children under the age of five and those living in high-burden countries like Nigeria. Long-lasting insecticidal nets (LLINs) are one of the effective interventions for malaria control and prevention. In response to funding constraints in the Global Fund Grant Cycle 7, Nigeria's National Malaria Elimination Programme (NMEP) aimed to develop an approach that maximizes the impact of limited malaria interventions by focusing on areas with the greatest need.

Geo-behavioural predictors of diagnosed hypertension in Igbo Ora Area, Oyo State, Nigeria.

Diagnosed hypertension stands out as a prominent global cause of mortality, prompting recent efforts to understand not only treatment options but also determinants across diverse age and occupational groups. However, the literature on the impact of environmental factors on diagnosed hypertension is limited, especially in rural areas with restricted access to health infrastructure. Geographical determinants research has often focused on spatial variations across different units, potentially masking individual environmental contributions.

Statistical exploration of factors associated with birth of children having sickle cell traits among reproductive-age women in Nigeria.

Background: Despite the relatively high prevalence of Sickle cell trait (SCT) in Nigeria, there has been little research into the correlates of having children with SCT among Nigerian mothers, particularly in terms of socio-demographic differentials. This study aims to investigate the maternal socio-demographic correlates of having under-five children with SCT in Nigeria.

Method: Data from the 2018 Nigeria Demographic and Health Survey (Household Person Recode and Children Recode) were merged.

Understanding malaria treatment patronage from informal healthcare providers in Nigerian urban settlements: insights from community members and providers.

Background: Informal Healthcare Providers (IHCPs), including Proprietary Patent Medicine Vendors (PPMVs), drug peddlers, traditional healers, and herbal drug sellers are often the first choice for malaria treatment, especially in urban slums. Unplanned urbanization significantly impacts malaria transmission by creating cities with inadequate safety nets and healthcare access, increasing reliance on IHCPs. While the World Health Organization recognizes IHCP's crucial role and emphasizes integrating them into formal healthcare for improved malaria care, they lack requisite training in malaria management and operate outside official regulations, raising concerns about the quality of care they provide.

Are urban residents seeking appropriate care for malaria? evidence from an exploratory qualitative study in two cities in nigeria.

Background: Unplanned and rapid urbanization within Nigerian cities with the attendant environmental consequences may hinder achieving malaria elimination goal. Presently, there are limited qualitative studies on malaria case management and care-seeking patterns by settlement type in urban areas in Nigeria. This study, investigated malaria-related health seeking behaviours among different settlement types in Ibadan and Kano metropolises, Nigeria.
