In youth, a preoccupation with weight and the desire to be thinner, or drive for thinness, might persist into adulthood and predict reward-based compulsive eating and greater weight status.
A total of 623 women were enrolled from a prospective cohort study starting at 10 years old and assessed up to 20 years later. Drive for thinness was measured five times during adolescence. In adulthood (mean age = 39.5), drive for thinness, reward-based eating drive, and BMI were measured.
Structural equation modeling found cumulative adolescent drive for thinness predicted higher scores for both adult drive for thinness and reward-based eating drive. Youth drive for thinness was not directly associated with adult BMI but rather indirectly through adult drive for thinness. Reward-based eating drive was not associated with adult BMI.
Drive for thinness during the critical developmental years may exert long-term effects on adulthood eating behaviors tied to greater weight gain, potentially reflecting an important early target of intervention.
在青年时期，对体重的关注和变瘦的愿望，或者对苗条的追求，可能会持续到成年，并预测基于奖励的强迫性进食和更高的体重状态。
共有 623 名女性参与了一项前瞻性队列研究，该研究从 10 岁开始，最多可评估 20 年。在青春期期间，对苗条的渴望进行了五次测量。在成年期（平均年龄为 39.5 岁），对苗条的渴望、基于奖励的进食驱动力和 BMI 进行了测量。
结构方程模型发现，青少年时期累积的对苗条的渴望预测了成年后对苗条的渴望和基于奖励的进食驱动力的得分更高。青少年时期的苗条渴望与成年 BMI 没有直接关联，而是通过成年后对苗条的渴望间接关联。基于奖励的进食驱动力与成年 BMI 无关。
在关键的发育阶段对苗条的渴望可能会对成年后的饮食行为产生长期影响，导致体重增加，这可能反映了一个重要的早期干预目标。
