Biographical  Sketch

 Charles E. Yesalis, M.P.H., Sc.D.

Dr. Yesalis received his Bachelor of Science and Master of Public Health degrees from the University of Michigan and he was awarded his doctoral degree by the Johns Hopkins University School of Hygiene and Public Health in 1975. He then joined the faculty at Johns Hopkins for one year. Dr. Yesalis was a member of the Department of Preventive Medicine and Environmental Health at the University of Iowa, College of Medicine from 1976-1986. From 1986-2006 he was Professor of Health Policy and Administration and Exercise and Sport Science at The Pennsylvania State University.

For the past twenty-eight years, much of Dr. Yesalis' research has been devoted to the non-medical use of anabolic-androgenic steroids (AS) and other performance-enhancing drugs and dietary supplements. In 1988 he directed the first national study of AS use among adolescents and was the first to present evidence of psychological dependence on AS. In addition, he has studied the incidence of AS use among elite power lifters, collegiate athletes, and professional football players. In 1993, using nationwide data, he demonstrated the association between AS use and violent behavior as well as an association with the use of other illicit drugs and alcohol. He also presented an estimate of lifetime AS use in the U.S. population (over one million). A recent study conducted by Dr. Yesalis showed a significant increase in AS use among teenage girls and boys since 1990. In 1998 he wrote The Steroids Game which focuses on prevention, education, and intervention regarding AS use by adolescents. He is the editor of a medical reference text, Anabolic Steroids in Sport and Exercise (2nd ed.) and co-editor of Performance Enhancing Substances in Sport and Exercise.

On six occasions he has been asked to testify before U.S. Congress on legislation related to the control of AS and growth hormone abuse. Dr. Yesalis has been a consultant to, among others, the U.S. Office of National Drug Control Policy, U.S. Senate and House of Representatives, the Drug Enforcement Administration, the Centers for Disease Control and Prevention, the Food and Drug Administration, Center on Addiction and Substance Abuse: National Commission on Sports and Substance Abuse, the NFL Players Association, the U.S. Olympic Committee, the National Collegiate Athletic Association, and the National Strength and Conditioning Association.
