This study examined whether different types of media affect the use of dietary proteins and amino acid supplements, and intent to use anabolic-androgenic steroids. A random sample of 618 boys aged 11-18 years from eight schools in the Flemish part of Belgium completed standardized questionnaires as part of the Media and Adolescent Health Study. The survey measured exposure to sports media, appearance-focused media, fitness media, use of dietary supplements, and intent to use anabolic-androgenic steroids. Data were analyzed using logistic regressions and are presented as adjusted odds ratios (OR) and 95 % confidence intervals (CI); 8.6 % indicated to have used dietary proteins, 3.9 % indicated to have used amino acid supplements, and 11.8 % would consider using anabolic-androgenic steroids. After adjusting for fitness activity, exposure to fitness media was associated with the use of dietary proteins (OR = 7.24, CI = 2.25-23.28) and amino acid supplements (5.16, 1.21-21.92; 44.30, 8.25-238). Intent to use anabolic-androgenic steroids was associated with exposure to fitness media (2.38, 1.08-5.26; 8.07, 2.55-25.53) and appearance-focused media (6.02, 1.40-25.82; 8.94, 1.78-44.98). Sports media did not correlate with the use of dietary supplements and intent to use anabolic-androgenic steroids. Specific types of media are strong predictors of the use of supplements in adolescent boys. This provides an opportunity for intervention and prevention through the selection of fitness media as a communication channel. Health practitioners should also be aware that the contemporary body culture exerts pressure not only on girls but also on boys.
本研究旨在探讨不同类型的媒体是否会影响青少年对膳食蛋白质和氨基酸补充剂的使用以及对合成代谢类固醇的使用意向。在比利时佛兰德斯地区的 8 所学校中，随机抽取了 618 名年龄在 11-18 岁的男孩，让他们填写标准化问卷，作为媒体与青少年健康研究的一部分。该调查测量了他们接触运动媒体、关注外貌的媒体、健身媒体、使用膳食补充剂以及使用合成代谢类固醇的意向。研究采用逻辑回归分析数据，并以调整后的优势比（OR）和 95%置信区间（CI）呈现结果；8.6%的男孩表示曾使用过膳食蛋白质，3.9%的男孩表示曾使用过氨基酸补充剂，11.8%的男孩表示可能会考虑使用合成代谢类固醇。在调整健身活动后，接触健身媒体与使用膳食蛋白质（OR=7.24，95%CI=2.25-23.28）和氨基酸补充剂（OR=5.16，95%CI=1.21-21.92）呈正相关；接触健身媒体还与使用合成代谢类固醇的意向（OR=2.38，95%CI=1.08-5.26）和关注外貌的媒体（OR=6.02，95%CI=1.40-25.82）呈正相关；而接触运动媒体与使用膳食补充剂和使用合成代谢类固醇的意向均无关联。特定类型的媒体是青少年男孩使用补充剂的有力预测因素。这为通过选择健身媒体作为沟通渠道来进行干预和预防提供了机会。健康从业者还应该意识到，当代的身体文化不仅对女孩，而且对男孩都施加了压力。
