Prevalence and correlates of appearance- and performance-enhancing drugs and substances use among a national sample of college students aged 18-30.

Objective: To identify the lifetime prevalence and correlates of appearance- and performance-enhancing drugs and substances (APEDS) use among a national sample of US college and university students. Participants: Student participants from the 2020-2021 Healthy Minds Study (N = 7,401; ages 18-30 years). Methods: Lifetime prevalence of five forms of APEDS was estimated. Modified Poisson regression analyses were conducted to determine the sociodemographic correlates of protein and creatine supplement use. Results: Lifetime protein (23.8%) and creatine (7.7%) supplement use were most common among the sample. Older age within young adulthood, male sex, perceiving oneself to be normal weight or somewhat overweight, any athletics participation, and 2-3 or ≥ 5 h/week of exercise were associated with greater likelihood of lifetime protein and creatine supplement use. Conclusions: Awareness and prevention efforts on the potential harms of APEDS use are needed on campuses, particularly among males and those who participate in athletics and high-frequency exercise.
