title: Levels of health development: a new tool for comparative research and policy formulation.
abstract: Levels of health development are formed by mathematically clustering countries using six health status indicators: crude birth, crude death, infant mortality and child death rates, and male and female life expectancy. Stratifying two international samples of 128 and 163 countries into levels of health development--groups with similar health status profiles--improves the results of regression analyses used to identify economic, political, social, educational, health and other health determinants. For this reason, health development levels are a systematic framework for delineation of health determinants. Earlier large scale statistical studies have been limited in their success in part because they did not partition their data sets prior to analysis, or used inappropriate criteria that blurred rather than heightened developmental differences in underlying social systems. These developmental differences regulate the way in which health status inputs are converted into health status outputs, defining the relative importance of health determinants at various developmental levels. At lowest health development levels (countries with poorer health status), the under-development of economic, health and educational infrastructures creates a vacuum which allows international intervention (aid, investment, export/import activities) to play a dominant role in health status determination. At middle health development levels, health and educational infrastructures are better developed, but still secondary in importance as health status determinants to basic economic infrastructure. Demographic problems are particularly apparent at these levels. At higher health development levels, education, women's status, and political structure are especially important health status determinants. This research has facilitated the identification of health status determinants for use in health policy analysis. Recommendations for future research include use of findings in health policymaking by individual countries and by comparative researchers, and development of appropriate health systems models for each level of health development.
