I would also like to thank Dr. George Crothers and Nancy O’Malley at the University of Kentucky for allowing me to access the Indian Knoll collection, and for their assistance during the time I spent at the William S. Webb Museum of Anthropology. Lastly, I would like to thank my wonderful family for providing me with the encouragement I needed to complete the project. iii ABSTRACT DETECTING EVIDENCE OF SYSTEMIC INFLAMMATION FROM OSTEOLOGICAL MARKERS IN THE INDIAN KNOLL POPULATION OF OHIO COUNTY, KENTUCKY Krysta N. Wilham November 21, 2016 Indian Knoll is an Archaic shell midden site located in the Green River region of west-central Kentucky, and was excavated twice in the first half of the 20 th century. While Indian Knoll has been the subject of frequent bioarchaeological studies, the present study presents an osteological analysis of the relationships between skeletal markers commonly associated with local inflammatory processes, and that have the potential to be used as proxies for systemic inflammation. The analysis revealed a significant positive association in the presence of periodontal disease (PD) and periosteal lesions (PL), suggesting a potential underlying hyper-inflammatory status or phenotype. These findings may indicate that different stress factors could have induced a shift in systemic inflammation. Significant positive associations were also observed between PD and age, and PL and age, which indicate an age effect. The present study also explored the associations between additional inflammatory lesions, and comparisons between age and sex. iv TABLE OF CONTENTS ACKNOWLEDGEMENTS
