What is more strongly related to disordered eating in male surfers, body fat or muscularity?

Abstract AIMS This study aimed to analyze the relationship between disordered eating (DE) and dissatisfaction with body fat and the drive for muscularity in male surfing athletes. METHODS The research included a sample of 175 surfers. The Eating Attitudes Test was used to assess DE. It was used the Body Shape Questionnaire to assess body dissatisfaction based on body fat. It was used the Drive for Muscularity Scale to evaluate the drive for muscularity. RESULTS The multinomial regression model showed a statistically significant association between DE and both body dissatisfaction based on body fat (Wald = 22.97, OR = 3.86) and the drive for muscularity (Wald = 12.38, OR = 1.84). CONCLUSION It was concluded that there is relationship between body dissatisfaction based on body fat and DE. Likewise, there is relationship between drive for muscularity and DE in male surfers.

摘要
## 研究目的
本研究旨在探讨男性冲浪运动员的进食紊乱（disordered eating）与体脂相关身体不满及肌肉渴望之间的关联。
## 研究方法
本研究纳入175名冲浪运动员作为研究样本。采用进食态度测验（Eating Attitudes Test）评估进食紊乱情况；采用身体形态问卷（Body Shape Questionnaire）评估基于体脂的身体不满程度；采用肌肉渴望量表（Drive for Muscularity Scale）评价肌肉渴望水平。
## 研究结果
多项回归模型（multinomial regression model）分析结果显示，进食紊乱与体脂相关身体不满（沃尔德统计量=22.97，优势比OR=3.86）以及肌肉渴望（沃尔德统计量=12.38，优势比OR=1.84）均存在统计学意义上的关联。
## 研究结论
本研究得出结论：男性冲浪运动员中，体脂相关身体不满与进食紊乱存在关联；同样，肌肉渴望与进食紊乱亦存在关联。
