The main thrust of the study is investigate the main socio-economic and demographic antecedents and proximate factors influencing Infant Mortality Levels and Patterns in Sub-Saharan African The source of data of the study is largely from the 2001-2005 UNDP Human Development Reports, National Census Results, DHS data and Demographic survey results of Sub-Saharan African Countries. The analytical techniques include analysis of univariate and bivaraite frequency distributions,  ANOVA, correlation matrix  and Multivariate regression models. Each country is taken as the unit of observation and a total of 42 countries are covered. The dependent variable is the level of Infant Mortality whereas 14 independent variables as the predictors influencing the Infant Mortality conditions are considered.   The model outputs suggested that all the fourteen independent covariates appeared to influence the levels of infant mortality positively or negatively, but in varying values of statistical significance, due to multicollinearity among the independent variables as manifested in the correlation matrix which appear to hinder clear understanding of  the impact of each independent variable on infant mortality. However, the stepwise regression output identified the critical covariates of the infant mortality levels. In conclusion, the study indicated that persistent high infant mortality level in the African -Continent has yet to continue for some decades before coming down to acceptable levels. The main reasons which largely appeared to maintain high Infant Mortality Levels among the Sub-Saharan Countries were noted to be the widespread poverty conditions and low level of health services and education in rural Sub-Saharan Africa. Consequently, the high infant mortality in rural Africa has been observed to be influenced by high fertility level, family planning programmes, education and employment, among other background and proximate variables.

Background: Patients with human immunodeficiency virus (HIV) in the modern era are at risk of developing cardiovascular diseases. High blood pressure (BP) is common in sub-Saharan Africa, however, global attention in the region has been mostly focused on HIV. The impact of BP on mortality among adults with HIV in this region has not been reported. Objective: The objective was to determine the impact of BP on mortality among HIV seropositive (+) adults without acquired immune deficiency syndrome (AIDS) in Kenya. Methods: We conducted a retrospective analysis of de-identified medical records of the Academic Model Providing Access to Healthcare HIV treatment program between 2005 and 2010. We excluded patients with AIDS, who were <16 or >80 years old, or with data out of acceptable ranges. There were 49,475 HIV+ individuals who satisfied inclusion/exclusion criteria (Figure 1). Missing data for key covariates was addressed by inverse probability weighting. We summarize crude mortality rates across BP categories, separately by gender. We used proportional hazards regression models to characterize the effect of BP on mortality, adjusting for baseline demographic and clinical factors. We subdivided the sample according to those who were clinically stable, defined as having ≥CD4 350 or WHO Stage 1. Results: Our sample was 74% (36,616 of 49,475) women. Mortality rates for men and women were 3.8/100 and 1.8/100 person-years, respectively. Crude mortality rate among clinically stable men was higher with systolic BP ≥140 mmHg (3.0, 95% CI: 1.6-5.5) than with normal systolic BP (1.1, 95% CI: 0.7-1.7). In weighted proportional hazards regression models, clinically stable men with systolic BP ≥140 mmHg carried a higher mortality risk than normotensive men (HR: 2.39, 95% CI: 0.94 to 6.08). Conclusions: Blood pressure is an important aspect of the care of HIV+ patients in sub-Saharan Africa. High systolic BP is associated with mortality among clinically stable men without AIDS. Further investigation into cause of death in warranted.

African countries, like many other developing countries, suffer the problems associated with poverty—malnutrition, poor health services, high infant mortality rates, low life expectancy, high illiteracy rates, poor infrastructure, and inadequate technology. These problems are especially severe in Sub-Saharan Africa.

BackgroundAnti-retroviral therapy (ART) regimes for HIV are associated with raised levels of circulating triglycerides (TGs) in western populations. However, there are limited data on the impact of ART on cardiometabolic risk in sub-Saharan African (SSA) populations.MethodsPooled analyses of 14 studies comprising 21 023 individuals, on whom relevant cardiometabolic risk factors (including TG), HIV and ART status were assessed between 2003 and 2014, in SSA. The association between ART and raised TG (>2.3 mmol/L) was analysed using regression models.FindingsAmong 10 615 individuals, ART was associated with a two-fold higher probability of raised TG (RR 2.05, 95% CI 1.51–2.77, I2 = 45.2%). The associations between ART and raised blood pressure, glucose, HbA1c, and other lipids were inconsistent across studies.InterpretationEvidence from this study confirms the association of ART with raised TG in SSA populations. Given the possible causal effect of raised TG on cardiovascular disease (CVD), the evidence highlights the need for prospective studies to clarify the impact of long term ART on CVD outcomes in SSA.

The article considers the impact of the colonial past of some countries in sub-Saharan Africa and its effect on their development during the post-colonial period. The negative consequences of the geopolitical legacy of colonialism are shown on the example of three countries: Nigeria, the Democratic Republic of the Congo and the Republic of Angola, expressed in the emergence of conflicts in these countries based on ethno-cultural, religious and socio-economic contradictions. At the same time, the focus is made on the economic factor and the consequences of the consumer policy of the former metropolises pursuing their mercantile interests were mixed.

This study evaluates the relevance of inclusive financial access in moderating the effect of income inequality on economic growth in 48 countries in Sub-Saharan Africa (SSA) for the period 1995 to 2017. The findings using the Generalised Method of Moments (sys-GMM) technique show that inclusive financial access contributes to reducing inequality in the short run, contrary to the Kuznets curve. The result reveals a negative effect of financial access on the relationship between income inequality and economic growth. There is a positive net effect of inclusive financial access in moderating the impact of income inequality on economic growth. Given the need to achieve the Sustainable Development Targets in the sub-region, policymakers and other stakeholders of the economy must design policies and programmes that would enhance access to financial services as an essential mechanism to reduce income disparity and enhance sustainable economic growth.

By 2050, half of the net increase in the world’s population is expected to reside in sub-Saharan Africa (SSA), driving high urbanization rates and drastic land cover changes. However, the data-scarce environment of SSA limits our understanding of the urban dynamics in the region. In this context, Earth Observation (EO) is an opportunity to gather accurate and up-to-date spatial information on urban extents. During the last decade, the adoption of open-access policies by major EO programs (CBERS, Landsat, Sentinel) has allowed the production of several global high resolution (10–30 m) maps of human settlements. However, mapping accuracies in SSA are usually lower, limited by the lack of reference datasets to support the training and the validation of the classification models. Here we propose a mapping approach based on multi-sensor satellite imagery (Landsat, Sentinel-1, Envisat, ERS) and volunteered geographic information (OpenStreetMap) to solve the challenges of urban remote sensing in SSA. The proposed mapping approach is assessed in 17 case studies for an average F1-score of 0.93, and applied in 45 urban areas of SSA to produce a dataset of urban expansion from 1995 to 2015. Across the case studies, built-up areas averaged a compound annual growth rate of 5.5% between 1995 and 2015. The comparison with local population dynamics reveals the heterogeneity of urban dynamics in SSA. Overall, population densities in built-up areas are decreasing. However, the impact of population growth on urban expansion differs depending on the size of the urban area and its income class.

AbstractMastitis is a disease of livestock that directly impede livestock production and thus hindering the socio-ecological development of sub-Saharan Africa. Studies have estimated the prevalence of this disease in 30% of Africa countries, with Ethiopia having the highest prevalence. The coverage is low, despite the wide livestock and dairy farms distribution in Africa. Furthermore, estimated economic losses due to the impact of mastitis are lacking in Nigeria. The disease is endemic in Nigeria as indicated by the available data and there are no proposed management plans or control strategies. This review is thus presented to serve as a wakeup call to all parties involved to intensify efforts towards the diagnosis, control, and management of the disease in Nigeria.
