This study aimed to determine the prospective association between creatine monohydrate use and muscle dysmorphia symptomatology among adolescents and young adults in Canada. Data from 912 adolescents and young adults from the Canadian Study of Adolescent Health Behaviors were analyzed. Creatine monohydrate use in the past 12 months was assessed at Wave 1, and muscle dysmorphia symptomatology was measured using the Muscle Dysmorphic Disorder Inventory (MDDI) at Wave 1 and Wave 2. The prospective associations between creatine monohydrate use and the MDDI total score and subscale scores were determined using linear regression analyses. Regression analyses controlled for relevant demographic identifiers, prior substance use, and the corresponding Wave 1 MDDI variable. Creatine monohydrate use at Wave 1 was prospectively associated with both total muscle dysmorphia symptomatology (B 1.34, 95 % CI 0.27, 2.42) and greater Appearance Intolerance (B 0.52, 95 % CI 0.02, 1.03) at Wave 2. Importantly, these findings were independent of prior muscle dysmorphia symptomatology, lifetime anabolic-androgenic steroid use, lifetime cigarette use, and frequency of alcohol use. Creatine monohydrate is commonly used among adolescents and young adults. Findings from this study are among the first to document that creatine monohydrate use may be a risk factor for the development of muscle dysmorphia symptomatology among adolescents and young adults. Health and mental health care professionals may consider assessing for both creatine monohydrate use and muscle dysmorphia symptomatology among adolescents and young adults.
本研究旨在确定在加拿大青少年和年轻人中肌酸一水合物的使用与肌肉变形症症状之间的前瞻性关联。对来自加拿大青少年健康行为研究的 912 名青少年和年轻人的数据进行了分析。在第 1 波评估了过去 12 个月内肌酸一水合物的使用情况，在第 1 波和第 2 波使用肌肉变形障碍量表（MDDI）测量了肌肉变形症症状。使用线性回归分析确定了肌酸一水合物的使用与 MDDI 总分和子量表得分之间的前瞻性关联。回归分析控制了相关的人口统计学标识符、先前的物质使用以及相应的第 1 波 MDDI 变量。第 1 波的肌酸一水合物使用与总肌肉变形症状（B1.34，95%CI0.27，2.42）和更大的外貌不耐受（B0.52，95%CI0.02，1.03）在第 2 波呈前瞻性相关。重要的是，这些发现独立于先前的肌肉变形症状、终生合成代谢雄激素类固醇使用、终生吸烟和酒精使用频率。肌酸一水合物在青少年和年轻人中广泛使用。本研究的结果是首次记录肌酸一水合物的使用可能是青少年和年轻人肌肉变形症状发展的危险因素之一。健康和精神健康护理专业人员可能会考虑在青少年和年轻人中评估肌酸一水合物的使用和肌肉变形症状。
