Abstract

Background: The extent and implications of muscle building protein supplement use among adolescents is relatively unknown. We aim to present the prevalence of protein powder, creatine, and anabolic steroid use in a sample of 14-16 year-old boys in Australia, and the predictors of use, and intentions to use protein powder. Methods: Data were obtained from questionnaires with N=237 Australian adolescent boys aged 14-16 years from one independent boy’s school in Melbourne Australia. Hierarchical linear and logistic regressions were used to determine the predictors of intentions to use, and actual use of protein powder, respectively. Results: 49.8% of boys reported current use of, and 62% intended to use protein powder; 8.4% used creatine, and 4.2% used anabolic steroids. Higher levels of participation in drive for muscularity, weight training, and playing a greater number of sports were significant predictors of higher current use and higher intentions to use protein powder, but age, BMI, body esteem, and ethnicity were not. Conclusions: Prevalence of muscle building supplement use was relatively high among this adolescent population. This research has implications for intervention and prevention programs to educate young boys about muscle building supplements to reduce negative physical and psychological health effects of their use.
