The coronavirus disease 2019 (COVID-19) pandemic may have short-term and long-term impacts on health services across sub-Saharan African countries. A telephone survey in Burkina Faso, Ethiopia, Nigeria was conducted to assess the effects of healthcare from perspectives providers (HCPs) community members. total 900 HCPs (300 each country) 1,797 adult members (approximately 600 participated study. Adjusted risk ratios (ARRs) 95% confidence intervals (CIs) were computed using modified Poisson...
This study aimed to determine the burden of depression, suicidal ideation and behaviour amongst adolescents at sites in six sub-Saharan African countries examine associated risk protective factors.Household-based cross-sectional involving male female ages 10-19 years. A total 7,662 from eight participated survey. Three were urban: Dar es Salaam (Tanzania), Harar (Ethiopia) Ibadan (Nigeria); five rural: Dodoma Iganga/Mayuge (Uganda), Kersa (Ethiopia), Ningo Prampram (Ghana) Nouna (Burkina...
Abstract Objective To examine knowledge of menstruation, HIV and STIs other than across eight sites in SSA to develop effective programmatic interventions enabling adolescents achieve positive SRH as their transition adulthood. Methods We combine data from Health Demographic Surveillance Sites sub‐Saharan Africa, an adolescent‐specific survey that included 7116 males females age 10–19 years old. provide pooled site‐specific estimates multiple analytic models examining the how year‐specific...
COVID-19 vaccine hesitancy among adolescents poses a challenge to the global effort control pandemic. This multi-country survey aimed assess prevalence and determinants of in sub-Saharan Africa between July December 2021. The was conducted using computer-assisted telephone interviewing five African countries, Burkina Faso, Ethiopia, Ghana, Nigeria, Tanzania. A rural area an urban were included each country (except which only had area), with approximately 300 2662 total. Sociodemographic...
Coronavirus disease 2019 (COVID-19) can have far-reaching consequences for developing countries through the combined effects of infection and mortality, mitigation measures that impact food systems diets. Using a mobile platform, this cross-sectional study evaluated effect COVID-19 on prices dietary quality 1797 households in Nouna Ouagadougou Burkina Faso, Addis Ababa Kersa Ethiopia, Lagos Ibadan Nigeria. We assessed consumption 20 groups during previous 7 days. The diversity scores (DDS)...
Coronavirus disease 2019 (COVID-19) is a public health emergency affecting the lives of millions people globally. Different measures and extraordinary steps are being taken to contain transmission virus. The levels knowledge implementation preventive practices related COVID-19 in sub-Saharan African countries unclear. Additionally, there lack evidence regarding impacts pandemic on mental health. This study aimed describe assess status among adults three countries: Burkina Faso, Ethiopia,...
The coronavirus disease 2019 (COVID-19) pandemic is an unprecedented public health crisis globally. Understanding healthcare providers' (HCPs') knowledge and perceptions of COVID-19 crucial to identifying effective strategies improve their ability respond the in sub-Saharan Africa. A phone-based survey 900 HCPs Burkina Faso, Ethiopia, Nigeria (300 per country) was conducted assess knowledge, perceptions, prevention measures, stigma, mental HCPs. Modified Poisson regression models were used...
BackgroundDespite lifelong and detrimental effects, the co-occurrence of health risk behaviors (HRBs) during adolescence remains understudied in low- middle-income countries. This study examines HRBs its correlates among adolescents sub-Saharan Africa, China, India.MethodsA multi-country cross-sectional was conducted 2021–2022, involving 9697 (aged 10–19 years) from eight countries, namely Burkina Faso, Ethiopia, India, Ghana, Nigeria, Tanzania, Uganda. A standardized questionnaire...
The African continent has some of the world’s lowest COVID-19 vaccination rates. While limited availability vaccines is a contributing factor, vaccine hesitancy among healthcare providers (HCP) another factor that could adversely affect efforts to control infections on continent. We sought understand extent HCP, and its factors in Africa. evaluated 1,499 HCP enrolled cross-sectional study conducted as telephone survey Burkina Faso, Ethiopia, Nigeria, Tanzania, Ghana between July December...
The coronavirus disease 2019 (COVID-19) pandemic has significant health and economic ramifications across sub-Saharan Africa (SSA). Data regarding its far-reaching impacts are severely lacking, thereby hindering the development of evidence-based strategies to mitigate direct indirect consequences. To address this need, Research, Implementation Science, Education (ARISE) Network established a mobile survey platform in SSA generate longitudinal data knowledge, attitudes, practices (KAP)...
There is very limited data on the extent and determinants of COVID-19 vaccine hesitancy among adults living in sub-Saharan Africa since global roll-out vaccines began 2021. This multi-country survey sought to investigate other predictors readiness get vaccinated. We conducted surveys residing nine urban rural areas Burkina Faso, Ethiopia, Ghana, Nigeria, Tanzania late Log binomial regression models were used identify prevalence factors associated with beliefs around misinformation. completed...
The production and exportation of petroleum plays a dominant role in Nigeria's economy. A drastic fall the quantity crude oil produced is fatal to Nigerian economy since Nigeria depends heavily on sector. Different classical statistical methods have been used model but application machine learning models has grossly understudied. In this study, we identified high-performance between (ARIMA) two (ANN RF) modeling Nigeria. monthly data collected from January, 2006 October, 2020 study secondary...
The public health measures instituted by governments to combat the coronavirus disease 2019 (COVID-19) may cause developmental and educational losses adolescents. impacts of COVID-19 pandemic its mitigation strategies on adolescents in sub-Saharan Africa are unclear.

A new compound distribution called the Marshall-Olkin Inverse Lomax (MO-ILD) was proposed, extending inverse by adding a parameter to existing distribution, leading greater flexibility in modeling various data types. Its basic statistical properties were derived and model parameters estimated using method of maximum likelihood. The Proposed applied Cancer Stem Cell compared Marshall Olkin Flexible Weibull Extension Distribution (MO-FWED), exponential (MO-EWD). provided better fit than...
Abstract Objectives We analysed mutually comparable surveys on adolescent attitudes and behaviours from nine sites in seven sub‐Saharan African countries, to determine the relationship between school enrolment health outcomes. Methods Data Africa Research, Implementation Science, Education Network cross‐sectional were used examine associations of current enrolment, self‐reported general four major domains: (i) sexual reproductive health; (ii) nutrition non‐communicable diseases; (iii) mental...
Background Globally, men who have sex with (MSM) continue to bear a disproportionately high burden of HIV infection. Rwanda experiences mixed epidemic, which is generalized in the adult population, aspects concentrated epidemic among certain key populations at higher risk infection, including MSM. Limited data exist estimate population size MSM national scale; hence, an important piece missing determining denominators use estimates for policy makers, program managers, and planners...
