Perceiving one's weight as "overweight" is associated with disordered eating in adolescence. Yet, it is unknown whether weight perceptions change during adolescence, or whether these weight perception transitions predict disordered eating. This study aims to: (1) characterize weight perception transitions from early to late adolescence among a population-based sample and (2) examine whether weight perception transitions in adolescence predict concurrent and future disordered eating into young adulthood.
Eating and Activity in Teens and Young Adults (N = 1,414) survey data were used to examine correlates of weight perception transitions from early (M = 14.9 ± 1.6 years) to late adolescence (M = 19.4 ± 1.6 years). Adjusted generalized estimating equations were used to determine whether weight perception transitions in adolescence predicted concurrent and future disordered eating in emerging adulthood (M = 25.2 ± 1.6 years) and young adulthood (M = 31.0 ± 1.6 years).
Weight perceptions were stable from early to late adolescence for 77.2% of adolescents, whereas 15.5% transitioned to perceiving their weight as "overweight" and 7.3% stopped perceiving "overweight" in late adolescence. Perceived "overweight", especially in late adolescence, was associated with higher concurrent and long-term disordered eating up to 10 years later. For example, the predicted prevalence of binge eating in young adulthood among individuals who perceived their weight as "overweight" throughout adolescence was 20.1% compared to 6.6% for those who never perceived their weight as "overweight" in adolescence.
Adolescent weight perception was relatively stable in this population-based sample. However, weight perception transitions that involved perceiving "overweight", particularly in late adolescence, were associated with long-term higher risk of disordered eating.
在青少年时期，将自己的体重视为“超重”与饮食失调有关。然而，目前尚不清楚体重感知是否会在青春期发生变化，或者这些体重感知的转变是否会预测饮食失调。本研究旨在：（1）描述从青春期早期到晚期的体重感知转变在基于人群的样本中的特征；（2）研究青春期的体重感知转变是否会预测进入成年早期的同时期和未来的饮食失调。
利用青少年和年轻人的饮食和活动（EAT）调查数据，研究了从青春期早期（M=14.9±1.6 岁）到晚期（M=19.4±1.6 岁）的体重感知转变的相关因素。调整后的广义估计方程用于确定青春期体重感知的转变是否预测成年早期（M=25.2±1.6 岁）和成年早期（M=31.0±1.6 岁）的同时期和未来的饮食失调。
77.2%的青少年从青春期早期到晚期的体重感知保持稳定，而 15.5%的人转变为认为自己的体重“超重”，7.3%的人在青春期晚期停止认为自己“超重”。在青春期后期，特别是感知到“超重”与更高的同时期和长期饮食失调有关，甚至可长达 10 年。例如，在整个青春期都认为自己体重“超重”的年轻人中，暴饮暴食的预测患病率为 20.1%，而在青春期从未认为自己体重“超重”的人中，这一比例为 6.6%。
在这个基于人群的样本中，青少年的体重感知相对稳定。然而，涉及到感知“超重”的体重感知转变，尤其是在青春期后期，与长期较高的饮食失调风险相关。
