Socioeconomic Inequalities in Health Financing: Retirement Income, Social Policies, and Health Outcomes in Nigeria
Year: 2025
Type: article
Abstract: - Nigeria faces persistent socioeconomic inequalities that shape health financing, access to care, and health outcomes. Retirement income insecurity, weak social protection, and high out-of-pocket (OOP) spending are important drivers of unequal healthcare utilization and catastrophic health expenditure. To synthesize evidence on how retirement income and social policy arrangements affect health financing equity and health outcomes among older adults in Nigeria, and to identify policy levers to reduce socioeconomic inequalities in health financing. A structured narrative review was conducted. Search strategies targeted peer-reviewed studies, government and multilateral reports, and recent policy analyses (2010–2025) relating to pensions, retirement income, health insurance coverage, out-of-pocket payments, and catastrophic health expenditure in Nigeria. Major data sources included PubMed/PMC, World Bank/WHO financial indicators, the National Pension Commission (PenCom), the National Health Insurance Authority (NHIA), and reputable news and policy outlets reporting post-2019 system changes. Findings were synthesized to identify consistent patterns, gaps, and policy implications. Evidence indicates extremely low health insurance coverage (formal NHIS coverage estimates below 10% in recent analyses), persistent reliance on OOP financing (OOP shares >60% of current health expenditure in many years), and very limited pension coverage — especially in the informal sector despite the 2014 Pension Reform Act and subsequent Micro-Pension initiatives. Retirees with irregular or inadequate pensions are less likely to use outpatient and preventive services and more likely to resort to informal coping (borrowing, asset sales) and experience catastrophic spending. Socioeconomic gradients are clear: poorer, informal, rural, and female retirees bear disproportionate financial risk. Recent policy efforts (Micro-Pension Plan, NHIA reforms) show promise but suffer from slow uptake, governance challenges, and implementation gaps. Strengthening retirement income security and expanding prepayment-based health financing (through scaling NHIA and linking pension beneficiaries to health insurance) are necessary to reduce inequalities in health financing and improve health outcomes among Nigeria’s ageing population. Policy priorities include expanding pension coverage in the informal sector, improving pension adequacy and regularity, accelerating NHIA reforms with targeted enrollment of retirees, and integrating social protection and health financing policy design.
