A crossectional country group study of three health level outcomes and four potential causes.
A crossectional study of four country groups segmented by per capita income of the majority of the world's countries was made to evaluate the relationship between health level outcomes and potential causes which may impact on the health level outcomes. The health level outcomes consist of life expectancy at birth, infant mortality rate and child mortality rate. The potential causes consist of secondary school children per 100 in school age group, daily calory supply per capita, population per physician and population per nurse. For the two lower income country groups the two important determinants of life expectancy were daily calory supply per capita and secondary school children per 100 in school age group. For the upper middle income the country group the important positive determinant of life expectancy was population per nurse and for the upper income country group the important negative determinant of life expectancy was daily calory supply per capita. Infant and child mortality rates were associated with secondary school children per 100 in school age group and population per physician or population per nurse for the two lower income country groups. For the upper middle income country group population per nurse or population per physician was supplemented by daily calory supply per capita for both infant and child mortality. For the upper income country group only infant mortality had statistically significant determinants. They were daily calory supply per capita and secondary school children per 100 in school age groups.
