Previous research done on the social determinants of health and allostatic load, a measure of cumulative wear and tear on the body due to chronic stress, set the foundation for this study. This thesis replicates prior studies that look at various factors and their relationship to allostatic load using data from the National Health and Nutrition Examination Survey from 2015-2020. I analyze how race and socioeconomic status affect allostatic load, and to the extent that the latter plays a mediating role. With a sample of 5,165 participants, I create a measure of allostatic load and conduct various multiple ordinal logistic regressions to run analyses. My findings show that certain racial/ethnic groups are more susceptible to or protected from a high allostatic load and people at a higher socioeconomic status are less likely to have a high allostatic load. The findings also indicate that race effects are mediated by socioeconomic status pathways.
