The aim of this study was to describe muscle dysmorphia (MD) symptomatology among a large, diverse, and national sample of adolescents and young adults in Canada. Data from the Canadian Study of Adolescent Health Behaviors (N = 2256) were analyzed. MD symptomatology was assessed using the Muscle Dysmorphic Disorder Inventory (MDDI). Men (mean [M] = 33.9, standard deviation [SD] = 8.6) reported significantly greater overall MD symptomatology compared to women (M = 30.1, SD = 7.3) and transgender/gender non-conforming (TGNC; M = 31.5, SD = 7.6) participants. Similarly, the prevalence of clinical MD risk was also highest among men (25.7 %). In regression analyses, participants who identified as South Asian (B 1.97, 95 % confidence interval [CI] 0.41, 3.52) or Middle Eastern (B 2.92, 95 % CI 0.50,5.35), compared to White participants, or identified as gay or lesbian (B 2.65, 95 % CI 1.19, 4.10), compared to heterosexual participants, had greater MD symptomatology. Findings are the first to describe the MD symptomatology among Canadian adolescents and young adults. Health care and public health professionals should be aware of the overall high occurrence of MD symptomatology in this sample, and future research is needed to continue to describe MD among Canadian young people.
本研究的目的是描述加拿大大量、多样且具有全国代表性的青少年和青年样本中的肌肉畸形症（MD）症状学。对加拿大青少年健康行为研究（N = 2256）的数据进行了分析。使用肌肉畸形症障碍量表（MDDI）评估MD症状学。男性（均值[M]=33.9，标准差[SD]=8.6）报告的总体MD症状学显著高于女性（M = 30.1，SD = 7.3）和跨性别/性别不一致（TGNC；M = 31.5，SD = 7.6）参与者。同样，临床MD风险的患病率在男性中也最高（25.7%）。在回归分析中，与白人参与者相比，自我认定为南亚人（B 1.97，95%置信区间[CI] 0.41，3.52）或中东人（B 2.92，95%CI 0.50，5.35）的参与者，或与异性恋参与者相比，自我认定为男同性恋或女同性恋的参与者（B 2.65，95%CI 1.19，4.10），具有更高的MD症状学。这些发现首次描述了加拿大青少年和青年中的MD症状学。医疗保健和公共卫生专业人员应意识到该样本中MD症状学的总体高发生率，未来需要继续开展研究以描述加拿大年轻人中的MD情况。
