Abstract
Socioeconomic Status (SES) indicators, such as educational attainment, are social determinants of heart disease. Marginalization related Diminished Returns (MDRs) refer to smaller health benefits of high SES for racial and ethnic minorities compared to the majority group. It is still unknown, however, if MDRs also apply to the effects of education on heart disease. Using a nationally representative sample, we explored racial/ethnic variation in the link between educational attainment and heart disease among American adults. We analyzed data (n=25,659) from a nationally representative survey of American adults in 2013. The first wave of the Population Assessment of Tobacco and Health - Adult (PATH-Adult) study was used. The independent variable was education (college graduate, high school graduate, less than a high school diploma). The dependent variable was any heart disease. Age and gender were the covariates. Race, as well as ethnicity, were the moderators. Logistic regressions were used to analyze the data. Individuals with higher educational attainment had lower odds of heart disease. Race and ethnicity showed statistically significant interactions with education, suggesting that the protective effect of higher education on reducing odds of heart disease was smaller for Hispanic and Black people than for non-Hispanic and White individuals. Education reduces the risk of heart disease better among non-Hispanic Whites than for Hispanics and Blacks. Therefore, we may expect a disproportionately higher than expected risk of heart disease in Hispanics and Blacks with high educational attainment. Future research should test if the presence of high levels of environmental and behavioral risk factors contribute to the high risk of heart disease in highly educated Black and Hispanic Americans. Policymakers should not reduce health inequalities to just gaps in SES because disparities are present across SES levels, with high SES Blacks and Hispanics remaining at risk of health problems.
Highlights
The health effects of socioeconomic status (SES) are well established [1 - 5], such effects are unequal across racial and ethnic groups [6 - 10]

Summary
The health effects of socioeconomic status (SES) are well established [1 - 5], such effects are unequal across racial and ethnic groups [6 - 10]. Considerable MDRs [6, 7] are shown in Blacks and Hispanics compared with Whites and non-Hispanics, documented as weaker effects of SES on the health of racial and ethnic groups [6, 7]. Marginalization related Diminished Returns (MDRs) refer to smaller health benefits of high SES for racial and ethnic minorities compared to the majority group. It is still unknown, if MDRs apply to the effects of education on heart disease. Purpose: Using a nationally representative sample, we explored racial/ethnic variation in the link between educational attainment and heart disease among American adults
