Katherine Newton, PhD, is a chronic disease epidemiologist who is passionate about finding ways to help women stay healthy during midlife. Known for her research on menopause, Dr. Newton is a national leader in the search for nonhormonal treatments for menopausal symptoms.
After a 20-year career as a cardiovascular nurse specialist, Dr. Newton pursued her PhD in epidemiology and shifted her focus to epidemiologic research, joining Kaiser Permanente Washington Health Research Institute (KPWHRI) as a postdoctoral fellow in 1995. Dr. Newton focuses on health concerns for women reaching midlife, especially menopause. Dr. Newton’s current goal is to help women transition through menopause in the healthiest way possible. She is especially interested in investigating ways to relieve menopause symptoms without using hormone replacement therapy.
Dr. Newton’s 2006 randomized trial of alternative therapies for menopause received widespread interest, leading to several invited talks around the world. Study analyses continue to yield compelling findings, including a 2007 publication linking low libido in menopause to trouble sleeping. She is currently participating in a multisite network of investigators, MsFLASH Finding Lasting Answers for Symptoms and Health. This group has conducted 6 randomized trials testing the efficacy of yoga, exercise, omega-3 fatty acids, escitalopram, and low-dose estrogen for menopause symptoms, and a study of telephone-based cognitive behavioral therapy for sleep among women with sleep problems related to menopause.
Dr. Newton is a member of the North American Menopause Society. She held two faculty appointments at the University of Washington: affiliate associate professor in epidemiology and affiliate associate professor in biobehavioral nursing and health systems.
