Economic Inequality and Infant, Under-5-Year-Old, Maternal, and Crude Mortality Rates

Mortality indices are among the most important health indicators in every country. On the other hand, mortality has an unequal distribution in different socioeconomic levels.. We sought to evaluate the association between economic inequality and infant, under-5-year-old, maternal, and crude mortality rates in the world..Patients and In this ecological study, data on 196 countries were obtained from the World Bank to assess the relation between economic inequality and mortality in 2013. Per capita gross domestic product (GDP), gross national income (GNI), out-of-pocket index, and per capita health expenditure were extracted as economic variables. Data analysis was performed using STATA, version 12.. The results showed that poorer countries had higher rates of infant, under-5-year-old, and maternal mortality. Among the economic indicators, per capita health expenditure, per capita GDP, and GNI had an important role in creating disparities, whereas the out-of-pocket index had no impact.. Per capita GDP, GNI, and per capita health expenditure played a significant role in creating disparities. Since per capita GDP and GNI are less variable, an increase in health expenditure can reduce inequality in mortality rates..
