This cross-sectional study aimed to examine the associations between body appreciation, body functionality and disordered eating in a large adolescent sample of different levels and types of sports practice. Method: The sample consisted of 1412 adolescents (59.8% were girls). The ages ranged from 15 to 18 years old, with a mean age of 16.9 (SD = 0.5) for girls and 17.0 (SD = 0.4) for boys. Participants completed an anonymous questionnaire assessing the nature of sports participation, body appreciation, body functionality, self-esteem, body dissatisfaction, internalisation of sociocultural beauty ideals and disordered eating. A two-way ANOVA was employed to test the differences in body image concerns, body appreciation, perceived physical fitness and disordered eating behaviours in gender groups and groups of different sport types and levels. Multiple linear regression analyses were performed to predict disordered eating behaviours of different study variables. Results: Participants of leisure and competitive sports reported greater body appreciation, self-esteem and lower body dissatisfaction compared to non-participants. No differences in body appreciation and disordered eating were observed in adolescents involved in weight-sensitive and less weight-sensitive sports. Body appreciation and body functionality were associated with lower disordered eating in adolescent girls not participating in sports, leisure exercisers and participants of competitive sport as well as in boys participating in competitive sports, controlling for body mass index. Adolescent boys demonstrated greater body appreciation compared to girls. Conclusions: The results of this study support the knowledge of the protective role of positive body image preventing dysfunctional eating in adolescent girls of various sports practice and in competitive sports involved boys. Disordered eating prevention and clinical treatment programs for adolescents of different physical activity might benefit from including education about body appreciation and functionality.

检查不同运动习惯的青少年的身体欣赏和饮食失调：跨部门研究。

这项横断面研究旨在检验在不同水平和类型的体育活动的青少年样本中，身体欣赏，身体功能与饮食失调之间的关联。方法：样本包括1412名青少年（59.8％为女孩）。年龄范围为15至18岁，女孩的平均年龄为16.9（SD = 0.5），男孩的平均年龄为17.0（SD = 0.4）。参与者完成了一项匿名问卷调查，评估了运动参与，身体欣赏，身体功能，自尊，身体不满，社会文化美理想的内在化和饮食失调的性质。采用双向方差分析法测试性别群体以及不同运动类型和水平的群体在身体形象关注，身体欣赏，感知的身体适应度和饮食失调行为方面的差异。进行了多元线性回归分析，以预测不同研究变量的饮食失调行为。结果：与非参与者相比，休闲和竞技运动参与者的身体欣赏能力，自尊心和较低的身体不满意程度更高。在体重敏感和体重敏感程度较低的青少年中，没有发现身体欣赏和饮食失调的差异。身体欣赏和身体机能与不参加运动的少女，休闲运动者和竞技运动参与者以及参加竞技运动的男孩（控制体重指数）的低度饮食失调有关。与女孩相比，青春期男孩表现出更高的身体欣赏能力。结论：这项研究的结果支持了在各种体育锻炼的青少年女孩和参与体育运动的男孩中，积极的身体形象预防机能不正常饮食的保护作用的认识。针对身体活动不同的青少年的饮食失调预防和临床治疗计划可能会受益于有关身体欣赏和功能的教育。
