Use of Legal Appearance- and Performance-Enhancing Drugs and Substances: Findings from the Canadian Study of Adolescent Health Behaviors

BackgroundUse of appearance- and performance-enhancing drugs and substances (APEDS) is common among adolescent and young adults. Many APEDS are legally sold "over-the-counter," however research has documented contamination of legal APEDS and many adverse effects of use. Despite this, little research has been conducted on legal APEDS use in Canada, particularly regarding the prevalence and sociodemographic predictors of use, which was the aim of this study.MethodsData from the Canadian Study of Adolescent Health Behaviors (N = 2,731) were analyzed. Prevalence and frequency of use of 10 common APEDS in the past 12 months were estimated overall and across genders. Multiple modified Poisson regression analyses were conducted to determine the sociodemographic predictors of APEDS use.ResultsOverall, use of caffeine was most common among the sample (71.3%), along with protein bars (63.4%), and whey protein powders or protein shakes (63.1%). Boys and men reported greater prevalence of use of eight of the 10 APEDS, with the exception of diuretics or water pills and probiotics, compared to girls and women and transgender/gender non-confirming participants. Over three quarters (82.5%) of boys and men reported use of whey protein powders or protein shakes and 50.3% reported use of creatine monohydrate. Use of APEDS varied based on several key sociodemographic identifiers.ConclusionsThis study is the first to document legal APEDS use among a sample of Canadian adolescents and young adults, providing important implications for health care and policymaking professionals. Further research is needed to gain greater insight into APEDS use among Canadian young people.
