Geographic Inequities in Catastrophic Health Expenditure in Sub-Saharan Africa: Multi-Threshold Evidence from Rural-Urban and Geopolitical Zone Disparities in Kogi State, Nigeria
Author(s): Moses Luke*, Abodunrin Gbenga and Adeoye Ojo
Background: Geographic location is a structural determinant of catastrophic health expenditure (CHE) in subSaharan Africa, yet intrastate analyses disaggregating disparities by residential classification and geopolitical zone remain scarce in Nigeria. Kogi State, with three senatorial districts exhibiting distinct facility densities and economic profiles, provides a subnational laboratory for examining how geography shapes CHE risk across Kogi West, Kogi East, and Kogi Central. Methods: A crosssectional household survey conducted in 2021 across all three senatorial districts of Kogi State included 403 household heads selected through multistage stratified sampling (response rate: 99.3%). CHE was defined using the WHO 40% threshold (OOP payments ≥40% of nonfood expenditure), with 10% and 20% thresholds used for sensitivity analysis. Geogra.. Read More»
