Kate Millington, MD

Dr. Millington’s research centers on the metabolic, endocrine, and cardiovascular health of transgender and gender-diverse (TGD) youth, with a particular emphasis on the physiological effects of gender-affirming hormone therapy. Specifically, she aims to use gender affirming care as a unique research paradigm through which to study sex dimorphic disease. Through her work with the Trans Youth Care – US study she has shown that multiple laboratory parameters such as hematocrit, cholesterol, creatinine, and others transition during gender affirming hormone therapy to the reference range that aligns with the patient’s gender. Her work has been published in journals such as JAMA Pediatrics, The Journal of Adolescent Health, Pediatrics, and Transgender Health, contributing essential data to a growing field at the intersection of endocrinology and gender health.   In addition, to the care of TGD youth Dr. Millington’s research and clinical interests include the early diagnosis and prevention of type 1 diabetes. She participates in advocacy to improve education around screening for type 1 diabetes and coordinates early treatment for type 1 diabetes at Hasbro Children’s. She is a gifted teacher and has won many teaching awards through her participation in the Doctoring program and pediatric clerkship at the Alpert Warren Medical School where she also co-directs the Endocrine Sciences course for pre-clinical students. She has mentored many medical students, residents, and fellows in her research program and in her clinical role. Through her research, Dr. Millington hopes to improve the care of TGD youth and all children as well as expand what is known about the role of sex hormones in human biology and disease.
