Emerging research suggests that positive body image—an overall love and respect for one’s body— may be a protective factor for eating disorder (ED) symptoms. This study aimed to explore the relationships between positive body image, ED symptoms, and related factors among men across time. A community sample of 440 British men completed questionnaires at Time 1 and Time 2 (1 year later). Linear models showed that, unexpectedly, positive body image at Time 1 did not predict change in ED symptoms at Time 2, and ED symptoms at Time 1 did not predict change in positive body image at Time 2. However, positive body image at Time 1 did predict increased appearance satisfaction and decreased appearance-ideal internalisation at Time 2. Increased positive body image at Time 2 was only predicted by appearance satisfaction at Time 1. Although no evidence for a longitudinal relationship between positive body image and ED symptoms was found, positive body image did predict change in established risk factors for disordered eating among men. Future research on positive body image and eating behaviour among men could be improved by including assessments of muscularity-oriented and adaptive eating behaviours.

新兴研究表明，积极的身体形象——对自己身体的整体爱和尊重——可能是饮食失调 (ED) 症状的保护因素。本研究旨在探讨男性积极身体形象、ED 症状和相关因素之间的关系。440 名英国男性的社区样本在时间 1 和时间 2（1 年后）完成了问卷调查。线性模型显示，出乎意料的是，时间 1 的阳性身体形象并不能预测时间 2 的 ED 症状的变化，时间 1 的 ED 症状并不能预测时间 2 的积极身体形象的变化。但是，时间 1 的积极身体形象确实预测了在时间 2 的外观满意度增加和外观理想内化减少。在时间 2 增加的积极身体形象仅由时间 1 的外观满意度预测。虽然没有发现积极的身体形象与 ED 症状之间存在纵向关系的证据，但积极的身体形象确实可以预测男性饮食失调的既定风险因素的变化。未来对男性积极身体形象和饮食行为的研究可以通过包括对肌肉导向和适应性饮食行为的评估来改进。
