How Does Social Inequality Alter Relationships Between Porous Cranial Lesions and Mortality? Examining the Relationship Between Skeletal Indicators of Stress, Socioeconomic Status, and Survivorship in a Pediatric Autopsy Sample

Abstract: BACKGROUND: In prior exploration of modern and archeological populations, lower SES has been associated with an increased risk of mortality. However, SES is often difficult to ascertain in archeological populations. Thus, explorations of skeletal lesions and their association with mortality may be subject to confounding factors that alter the strength and/or direction of this association. METHODS: The present study uses data from a modern, documented coronial pediatric dataset to examine the association between porous cranial lesions (PCLs) (cribra orbitalia [CO] and porotic hyperostosis [PH]) and age at death while controlling for SES, as inferred through housing type, with manufactured or apartment housing identified as reflecting individuals from lower SES backgrounds in this context. We include 887 (535 males, 352 females) individuals aged 0.5-20.9 years from New Mexico who died between 2011 and 2022. Kaplan-Meier survival analysis was used to assess survivorship as related to PCLs and SES. RESULTS: Low SES is associated with lower survivorship. CO does not have a significant association with age at death when not controlling for SES; PH alone is associated with older age at death. Disadvantaged individuals with PCLs have significantly reduced survivorship than those with higher SES. DISCUSSION AND CONCLUSIONS: The findings of this study demonstrate that low SES results in reduced survivorship, and those with low SES and PCLs have worse survivorship than less disadvantaged individuals with PCLs. Thus, the strong contribution of SES to mortality necessitates the consideration of the sociocultural context as a confounding factor when examining associations between variables of interest (such as lesions) and mortality in both past and present populations.
