The study examined the effect of National Health Insurance on health care service delivery Among Federal Workers in Nigeria. This mixed research design study investigates the relationships between primary and secondary health care service providers and the provision of essential healthcare services to enrollees in Nigeria. The population of the study encompasses federal governamnt workers with primary and secondary health care facilities across various regions in Nigeria. A sample size of 400 enrollees and 50 health care providers was selected using stratified random sampling techniques. Data were collected through structured interviews and surveys, focusing on the perceptions and experiences of both health care providers and enrollees regarding the provision of affordable health care, testing and diagnostic services, and referral services. The collected data were analyzed using both qualitative and quantitative methods, including thematic analysis and correlation analysis. The findings reveal significant relationships between primary health care service providers and the provision of affordable health care and testing and diagnostic services to enrollees in Nigeria. Moreover, the study identifies a significant relationship between secondary health care service providers and the provision of referral services to enrollees, highlighting the importance of collaboration between primary and secondary healthcare sectors to ensure comprehensive healthcare delivery in Nigeria. These results underscore the need for policy interventions and resource allocation strategies aimed at strengthening primary and secondary healthcare systems to improve access to essential healthcare services for all enrollees in Nigeria. The study recommends that Federal Government through the NHIA should implement policies that aim to increase the affordability of healthcare services for all citizens, especially those in lower socioeconomic strata. This may involve subsidizing healthcare costs, expanding insurance coverage, or introducing targeted assistance programs for vulnerable populations. Additionally, encourage healthcare providers to offer transparent pricing structures and explore innovative payment models, such as sliding-scale fees or income-based discounts, to improve access for individuals with varying financial capacities.

These articles investigate the relationship between income inequality and economic growth in the context of Sub-Saharan Africa (SSA). Using empirical methods and data from SSA countries, this study examines the impact of income inequality on various measures of economic growth, including gross domestic product (GDP) per capita, productivity, and human development indices. The analysis considers both the theoretical mechanisms underlying this relationship and the empirical evidence from SSA countries. The findings contribute to the understanding of the dynamics between income inequality and economic growth in the region, offering insights for policymakers and researchers.
