'ABSTRACT This research investigates the relations between Healthcare financing of both private and public sectors of selected countries in African against life expectancy and communicable & non-communicable diseases. Focusing on HIV prevalence within adult ages of 15 – 49 years for female, male and total population. Using secondary information from World Bank for 16 years ranging from 1999 to 2014. Results finding shows negative correlation on HIV prevalence as Healthcare Expenditure increases for total and public Healthcare Expenditure as shown by Pw correlation, Spearman correlation and Ktau correlation methods. Interestingly, it was found that HIV prevalence does not reduce within the adult female as Private Healthcare Expenditure increases, hence prompting a recommendation for future study to investigate miss use of funds, gender inequality, and literacy level in female adult, domestic violence and exposure level. Focusing on life expectancy; increasing healthcare expenditure for the evident countries in Africa is very important and cannot be under emphasized, these are low income developing countries, and therefore there is need to increase healthcare services resources; human resources, equipment, facilities and empowerment for the Results shows female population live longer than the male population, also there is positive relationship between the variables of healthcare spending and life expectancy at the public sector, while it is negative relationship between the variables for private healthcare sector. Focusing on communicable and non-communicable disease; this research investigates the relations between Healthcare Expenditure per capita for the total population of some selected countries in West African (W.E), against some selected communicable diseases and non-communicable diseases of the total population of these countries. Empirical results show negative relationship between HIV/AIDS death rate and tuberculosis against healthcare expenditure per capita for the communicable diseases. Also, for the non-communicable disease, it is a negative relationship between malaria, and vitamin A deficiency, and negative relationship between DPT against healthcare expenditure per capita. Focusing on mortality; it is very important to have clarity on which healthcare sector to invest in, in order to maximize impact, effectiveness, and efficiency. Hence the results and suggestions provided by this study. The relationship between healthcare spending (public and private) and health status is statistically significant. So, future research should focus on analyzing components of private healthcare spending such as direct household out-of-pocket spending, private insurance and direct service payments by private corporations as dependent variables to understand what form of private investment should be encouraged.
