ABSTRACTELIZABETH MOORE. Linear Enamel Hypoplasia: An Analysis of Health Disparities of the Peruvian Coast. (Under the direction of DR. DENNIS OGBURN)There has been an abundance of research, archaeological and other, on the Nasca culture and linear enamel hypoplasia (LEH) separately. However, there is no literature specifically on Nasca and LEH analysis comparing the Early Intermediate Period (EIP) stages of Early Nasca and Late Nasca, and the Middle Horizon period (MH). The research detailed here shows there are evident disparities in LEH between Nasca males and females correlating to status, cranial vault modification (CVM), and trophy heads, between the EIP and MH. On the other hand, fluctuations in LEH severity are similar between sexes due to shared experiences of stress linked to changes in environmental conditions and in socio-political organization. I utilized macroscopic observations of linear enamel hypoplasia on 47 Nasca individuals from the Kroeber collection from the Field Museum in Chicago, Illinois. Through this project, I found statistical significance between sex and trophy heads, cranial modification and LEH presence, and LEH between Early and Late Nasca periods. I conclude that while not statistically significant, but approaching significance, females tend to be more negatively impacted than males from similar stressors. Overall, health status deteriorated over time showing environmental changes and socio-political changes leading up to and during Wari imperial occupation had a negative effect on Nasca individuals, despite/regardless of status or sex. This presents a larger understanding on inequality and skeletal manifestations of such as well as a larger understanding of effects of environmental and socio-political stress on the skeleton.
