饮食失调行为在青少年中很普遍，可能会产生有害的后果。一个重要的问题是，青少年时期使用这些行为是否会为成年后继续使用这些行为设定模式。目的研究从青少年到成年早期节食、不健康和极端体重控制行为以及暴食的流行情况和追踪。设计（EAT-III项目：青少年和年轻人的饮食，1999 - 2010）参与者/环境研究人群包括2,287名年轻人（55%为女孩，52%为非白人）。样本包括年轻组（基线时平均年龄12.8 +/-0.7岁，随访时平均年龄23.2 +/-1.0岁）和老年组（基线时平均年龄15.9 +/-0.8岁，随访时平均年龄26.2 +/-0.9岁）。进行统计分析使用广义估计方程测试行为患病率的纵向趋势。跟踪的行为估计使用的相对风险的行为在后续给定的存在在baseline.Results在一般情况下，节食和饮食失调的患病率很高，并保持不变，或增加，从青春期到年轻的成年。此外，行为倾向于跟踪个人，一般来说，在青春期进行节食和饮食紊乱行为的参与者在10年后这些行为的风险增加。对于从青春期中期过渡到青年期中期的年龄较大的女孩和男孩来说，跟踪尤其一致。结论研究结果表明，饮食行为障碍不仅仅是青少年问题，而且在年轻人中仍然普遍存在。对个人节食和饮食失调的跟踪表明，早期使用可能会为持续使用奠定基础。研究结果表明，需要在有害行为模式发生之前进行早期预防工作，以及持续的预防和治疗干预措施，以解决整个青少年和青年期饮食失调的高患病率。J Am Diet Assoc.2011; 111：1004 - 1011.
Background Disordered eating behaviors are prevalent in adolescence and can have harmful consequences. An important question is whether use of these behaviors in adolescence sets the pattern for continued use into young adulthood.Objective To examine the prevalence and tracking of dieting, unhealthy and extreme weight control behaviors, and binge eating from adolescence to young adulthood.Design Population-based, 10-year longitudinal study (Project EAT-III: Eating Among Teens and Young Adults, 1999-2010).Participants/setting The study population included 2,287 young adults (55% girls, 52% nonwhite). The sample included a younger group (mean age 12.8 +/- 0.7 years at baseline and 23.2 +/- 1.0 years at follow-up) and an older group (mean age 15.9 +/- 0.8 at baseline and 26.2 +/- 0.9 years at follow-up).Statistical analyses performed Longitudinal trends in prevalence of behaviors were tested using generalized estimating equations. Tracking of behaviors were estimated using the relative risk of behaviors at follow-up given presence at baseline.Results In general, the prevalence of dieting and disordered eating was high and remained constant, or increased, from adolescence to young adulthood. Furthermore, behaviors tended to track within individuals and, in general, participants who engaged in dieting and disordered eating behaviors during adolescence were at increased risk for these behaviors 10 years later. Tracking was particularly consistent for the older girls and boys transitioning from middle adolescence to middle young adulthood.Conclusions Study findings indicate that disordered eating behaviors are not just an adolescent problem, but continue to be prevalent among young adults. The tracking of dieting and disordered eating within individuals suggests that early use is likely to set the stage for ongoing use. Findings suggest a need for both early prevention efforts before the onset of harmful behavioral patterns as well as ongoing prevention and treatment interventions to address the high prevalence of disordered eating throughout adolescence and young adulthood.
