Research on the social determinants of health has demonstrated robust correlations between several social factors, health status, and life expectancy. Some of these factors could be modifi ed through policy intervention. National-level public policies explicitly based on population health research are in various stages of development in many Western countries, but in spite of evident need, seemingly not at all in the United States. Because research shows such a strong association between education and good health, we offer evidence to show that at least two pressing problems in American society, namely the uneven distribution of educational attainment and health disparities linked to socioeconomic position, may be ameliorated through policy initiatives that link quality early childhood care, child development programs, and parental training in a seamless continuum with strengthened K-12 education.The central tenet of research on the social determinants of health holds that, in all populations studied to date, health is distributed unevenly, following a gradient that is a function of social and economic advantage (Evans and Stoddart 1994). The gradient does not just represent differences between people at the top and the bottom of the socioeconomic scale, but is continuous across even relatively small differences in social advantage. The gradient is steepest in countries such as the United States where there are large differences between people on measures of early childhood experiences, education, income, and housing quality. It is much less steep in countries such as Sweden, where income differences are smaller and policies that promote social integration and support have been normative for decades.
