Taylor Advisor Graduate Program in Allied Medical Professions COMPARISON OF NEONATAL OUTCOMES IN MATERNAL USERS AND NON-USERS OF HERBAL SUPPLEMENTS By Holly A. Larson, M.S. The Ohio State University, 2008 Dr. Maureen Geraghty, Advisor This pilot study was a retrospective chart review. The purposes of this study were to describe the prevalence herbal supplement use, to identify characteristics linked to increased herbal supplement use and, to identify adverse outcomes linked to herbal supplement use. Rate of use in the study sample of 2136 charts was 1.1% and identified 17 supplements. The most common supplements identified were teas. Characteristics of the neonates and controls were analyzed as appropriate and revealed no statistical significance. Characteristics of the mothers also revealed no statistical difference. There was a statistically significant difference between herbal users and herbal non-users and the trimester prenatal care began. Neonatal outcomes were statistically different on two measures. Further study is needed to be able to make recommendations regarding safety and efficacy of herbal supplements as well as to be able to better understand motives for choosing to use them. ii Dedicated to the Mama and the Daddy Bears iii ACKNOWLEDGMENTS I would like to express my heartfelt gratitude to my advisor, Dr. Maureen Geraghty.
