The extent and implications of muscle building protein supplement use among adolescents is relatively unknown. This study aimed to describe 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 actual use, and intentions to use protein powder.
Data were obtained from questionnaires with Australian adolescent boys aged 14-16 years from one independent boy's school in Melbourne (N = 237). Hierarchical linear and logistic regressions were used to determine the predictors of intentions, and actual use of protein powder.
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 drive for muscularity, participation in weight training, and playing a greater number of sports were significant predictors of higher current use and intentions to use protein powder, but age, BMI, body esteem, and ethnicity were not.
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.
青少年进行肌肉增强型蛋白质补充剂使用的程度和影响尚不清楚。本研究旨在描述澳大利亚 14-16 岁男孩样本中蛋白粉、肌酸和合成代谢类固醇的使用情况，以及实际使用和使用蛋白粉的意图的预测因素。
数据来自墨尔本一所独立男校的 14-16 岁青少年男孩的问卷（N=237）。使用分层线性和逻辑回归来确定蛋白粉的意图和实际使用的预测因素。
49.8%的男孩报告当前使用蛋白粉，62%的男孩打算使用蛋白粉；8.4%的男孩使用肌酸，4.2%的男孩使用合成代谢类固醇。更高的肌肉发达驱动力、参加重量训练以及参与更多的运动是当前使用和打算使用蛋白粉的更高水平的显著预测因素，但年龄、BMI、身体自尊和种族不是。
在这个青少年群体中，肌肉增强型补充剂的使用相当普遍。这项研究对干预和预防计划具有启示意义，这些计划旨在教育年轻男孩关于肌肉增强型补充剂的知识，以减少其使用对身心健康的负面影响。
