Abstract

Introduction: The financial burden of health care costs in Nigeria is borne almost entirely by the individuals and household members as health care financing is still mostly from out of pocket (OOP) payments. OOP payments can lead households into poverty.

International poverty line of $1.25 per day was used. Poverty level was measured with and without household health expenditure. An exact McNemar’s test was used to determine the difference in the proportion of poor, gross and net payment for health care services. SPSS software was used for data analysis.Results: Health care was utilised by 1,006 (70.2%) of the 1,434 households studied. Of urban and rural households, 637(89.2%) and 369(51.3%) utilized health care services, respectively. Only 513(29.8%) were poor while 1519(88.2%) were poor after considering the cost of utilising health care.
