Challenges to clinicians
An important point to recognize is that PES is a misleading term, Steven Cuff, MD, of the Ohio State University, Columbus, and Michele LaBotz, MD, of Tufts University, Boston, wrote in an accompanying editorial. “Most legal supplements marketed for athletic performance enhancement are ineffective at increasing muscle mass or athletic performance beyond what can be achieved through appropriate nutrition and training,” they emphasized. The current study findings suggest that “legal PES should be integrated into the gateway hypothesis regarding patterns and progression of substance use through adolescence and early adulthood,” and support discouragement of any PES use among adolescents and young adults.
Even legal PES can be dangerous because of the lack of oversight of dietary supplements by the Food and Drug Administration. “There is widespread evidence that many over-the-counter dietary supplements lack stated ingredients, contain unlabeled ingredients (including potential allergens), or are contaminated with impurities or illegal or dangerous substances, such as steroids and stimulants,” the editorialists emphasized.
In addition, the association found in the study between muscle dysphoria and both PES use and substance use disorders, notably alcohol-related morbidity, highlights the need for a proactive approach by pediatricians to minimize the risk, they noted.
“For pediatricians uncomfortable with initiating discussions on PES use with their patients, an American Academy of Pediatrics–supported role-play simulation is available,” they concluded.
The study is important because “PES use is ubiquitous among adolescents and young adults,” Dr. LaBotz said in an interview. “Although it is widely believed that PES use serves as a likely ‘gateway’ to use of anabolic steroids and other substances, this is one of the very few studies that explores this relationship. Their findings that alcohol use appears to correlate with subsequent use of PES, and that PES use appears to correlate with future alcohol-related issues, suggest that this is not a simple linear progression of problematic behavior.”
Dr. LaBotz added that she was not surprised by the study findings, and emphasized that pediatric health care providers should be aware of the association between PES and alcohol use. “PES screening should be incorporated into screening done for alcohol and other substance use. This appears to be particularly true for athletes and other subpopulations who are at higher risk for problematic alcohol use.”
She said much of PES use is driven by the desire by young men for a muscular appearance, but more research is needed on young women. “In the past, this was a goal primarily associated with males, but females have become increasingly interested in achieving muscularity as well, which suggests an increasing risk of PES use among females as compared to earlier reports. We need updated data on patterns, prevalence and consequences of PES use in females.”
In addition, “although preparticipation physical examination forms include screening questions for PES use among athletes, further information is needed on how to incorporate PES into substance use screening that is performed in a general pediatric population, such as including athletes and nonathletes,” Dr. LaBotz said.
The study was supported by the National Institutes of Health and by grants to one of the coauthors from the Pediatric Scientist Development Program funded by the American Academy of Pediatrics and the American Pediatric Society, as well as the American Heart Association Career Development Award.
