Risk factors associated with eating disorders (EDs) have been widely studied, although previous research has been limited to largely cross-sectional data or understanding risk factors in adult populations. Little is therefore known about the role of risk factors in early adolescence for the subsequent development of ED symptoms in adolescence.
The present study examined factors identified in transdiagnostic models of EDs, in a sample of 2,372 adolescents who participated in Waves 3, 4 and 7 of the Longitudinal Study of Australian Children. The present study examined the association between body dissatisfaction, negative emotional reactivity and self-esteem in adolescents aged 10-11, and probable ED status measured via self-report at age 16-17, while adjusting for confounders measured at age 8-9 years.
Negative reactivity and self-esteem at age 10-11 years were not significantly associated with ED status at age 16-17. Body dissatisfaction was associated with a decreased likelihood of meeting probable ED status at age 16-17, however this effect was small and likely not clinically significant, with only 2% of variance in probable ED status accounted for by body dissatisfaction.
Findings of the study suggest that transdiagnostic models of EDs may not capture the key risk factors for EDs in early adolescence.
饮食失调（EDs）相关的风险因素已得到广泛研究，尽管先前的研究大多局限于横断面数据或对成年人群风险因素的理解。因此，对于青春期早期风险因素在随后青春期饮食失调症状发展中的作用知之甚少。
本研究在2372名参与澳大利亚儿童纵向研究第3、4和7波的青少年样本中，考察了饮食失调跨诊断模型中确定的因素。本研究考察了10 - 11岁青少年的身体不满、负面情绪反应性和自尊之间的关联，以及16 - 17岁时通过自我报告测量的可能饮食失调状态，同时对8 - 9岁时测量的混杂因素进行了调整。
10 - 11岁时的负面反应性和自尊与16 - 17岁时的饮食失调状态无显著关联。身体不满与16 - 17岁时达到可能饮食失调状态的可能性降低有关，然而这种影响很小且可能无临床意义，身体不满仅占可能饮食失调状态变异的2%。
该研究结果表明，饮食失调的跨诊断模型可能未捕捉到青春期早期饮食失调的关键风险因素。
