Objectives: Life expectancy has extended and infant mortality has improved with the development of medical sciences and health care technology than ever before around the world. From these indicators, however, it is also true that the gap among these countries has even widened.
Methods: Analyses were made following two steps: First, a multivariate factor analysis was conducted to discover the correlation between both life expectancy and infant mortality and each explanatory variable used in this study. The analysis was expected to discover characteristics of explanatory variables on dependant variables. Second, a multiple regression analysis with exploratory factor analysis was conducted to identify key correlates with determinants of life expectancy and infant mortality.
Results: By the factor analysis, three clusters of variables appeared representing private expenditure on health, public expenditure on health, and social support each. And, an exploratory factor analysis found that public expenditure on health and social support were related with both life expectancy and infant mortality, whereas private expenditure on health was somewhat related with life expectancy but not with infant mortality.
Conclusion: Encouraging findings from the study were that public sector such as public expenditure on health or social support has an important role in improving health outcomes. Health policy makers should pay attention to the results from this study and take action for the betterment of our nation.
