INVESTIGATING THE LINK BETWEEN BIRTH RATE AND MATERNAL MORTALITY, ACCOUNTING FOR NIGERIA’S HEALTH CARE SPENDING AND POPULATION GROWTH
Keywords:
Birth Rate, Maternal Mortality, Healthcare Spending, Unit Root Test, OLS Regression, FMOLSAbstract
Maternal mortality refers to fatalities resulting from pregnancy or childbirth, whereas the birth rate is defined as the number of live births per 1,000 individuals, both of which are prevalent in Nigeria and other worldwide economies. This work is unprecedented because it offers a fresh analysis of the link between birth rate and maternal mortality, considering Nigeria’ Health care spending and population growth, aspects that previous studies have not explored. We collected secondary data from 1990 to 2023 using World Bank development indicators. The unit root test was used to eliminate the potential for unit roots to generate spurious results. The FMOLS indicates that birth rate positively affects maternal mortality in the long term; however, the OLS regression reveals that birth rate significantly increases maternal mortality, whereas population growth negatively and significantly impacts maternal mortality. The correlation study revealed modest negative relationship between maternal mortality rate and health care spending. The graphical method illustrates the inverse relationship between maternal mortality and health care spending. Consequently, to enhance the professional management of pregnancy-related issues and to render family planning accessible for low-income Nigerians, the Nigerian government should allocate an adequate budget for health care services and medical personnel. This will assist in regulating the birth rate; hence, mitigating excessive population expansion and reducing the nation’s maternal mortality rate.
