使用社区青少年样本，我们的目标是(A)经验性地得出饮食障碍(ED)症状组，(B)检查这些组在10年内的纵向稳定性，以及(C)确定与ED组的稳定性和通过青春期的过渡相关的风险因素。来自EAT项目队列的青年(N=2,287)参加了基线(1998-1999年)和10年后续行动(2008-2009年)。参与者在基线时完成人体测量，并在两个时间点完成关于进食障碍症状和风险因素的自我报告调查。前两个目标用潜伏期模型检验，第三个目标用多项Logistic回归检验。出现了三组人，并被标记为：(A)无症状，(B)节食，(C)饮食紊乱(例如，暴饮暴食，代偿行为)。在10年内，无症状组的成员稳定性最高，而节食组的成员过渡到任何组的可能性都是一样的。饮食失调组的人有75%的可能性在10年后继续属于有症状的组。我们发现，这些转变可以通过基线风险因素来预测。例如，抑郁症状比同龄人高一个标准差的青少年从无症状组过渡到饮食紊乱组的几率高53%(OR=1.53，95%CI 1.09-2.16)。在青春期和成年早期，勃起功能障碍群体之间的转变相对常见。通过在青春期早期针对自尊和家庭因素等危险因素，预防工作可能会得到改善。
Using a community adolescent sample, we aimed to (a) empirically derive eating disorder (ED) symptom groups, (b) examine the longitudinal stability of those groups over 10 years, and (c) identify risk factors associated with ED group stability and transition through young adulthood. Young people (N=2,287) from the Project EAT cohort participated at baseline (1998-1999) and at 10-year follow-up (2008-2009). Participants completed anthropometric measures at baseline and self-report surveys on disordered eating symptoms and risk factors at both time points. Latent transition modeling was used to test the first two aims and multinomial logistic regression was used for the third aim. Three groups emerged and were labeled as: (a) asymptomatic, (b) dieting, (c) disordered eating (e.g., binge eating, compensatory behaviors). Stability of group membership over 10 years was highest for those in the asymptomatic group, while those in the dieting group showed equal likelihood of transitioning to any group. There was a 75% chance that those in the disordered eating group would continue to belong to a symptomatic group 10 years later. We found that these transitions could be predicted by baseline risk factors. For example, adolescents with one standard deviation higher depressive symptoms than their peers had 53% higher odds (OR=1.53, 95% CI 1.09-2.16) of transitioning from the asymptomatic group to the disordered eating group. Transition among ED groups is relatively common during adolescence and early adulthood. By targeting risk factors such as self-esteem and familial factors in early adolescence, prevention efforts may be improved.
