在两项研究中，我们研究了感知的体重耻辱，适应不良饮食行为（研究1和2）和体重增加（研究2）之间的关系是否由对脂肪的恐惧（FOF）介导。在研究1中，189名参与者完成了饮食行为的测量（例如，情绪化和克制饮食），FOF，感知体重耻辱和身高和体重。在纵向设计的研究2中，参与者报告了他们感知的体重耻辱，FOF，并测量了他们的身高和体重;然后他们在10周后返回完成饮食行为的测量（例如，弹性约束、脊状约束和情绪化进食）以及身高和体重。我们研究了第1阶段体重耻辱对第2阶段饮食行为和体重增加的预测价值。此外，我们研究了FOF作为这些关系的中介。在研究1中，我们发现FOF显著介导了感知的体重耻辱和限制饮食行为之间的正相关关系（B=.13，CI：.09至.19）。在研究2中，我们发现感知到的体重耻辱可以预测10周内的体重增加，并且这种关系是由FOF（B=.31，CI：.03至.78）和严格限制饮食（B=.07，CI：.002至.28）介导的。灵活的约束和情绪化饮食行为之间的关系，知觉体重耻辱和体重增加的介质。对脂肪的恐惧可能是一个过程，通过这个过程，体重耻辱感导致适应不良的饮食行为和体重增加。了解这一重要过程可能会导致更有效的健康体重干预。
Across two studies, we examine if the relationships between perceived weight stigma, maladaptive eating behaviors (Study 1 & 2) and weight gain (Study 2) are mediated by fear of fat (FOF). In Study 1, 189 participants completed measures of eating behavior (e.g., emotional and restrained eating), FOF, perceived weight stigma and height and weight. In Study 2, a longitudinal design, participants reported their perceived weight stigma, FOF and had their height and weight measured; they then returned 10 weeks later to complete measures of eating behaviors (e.g., flexible restraint, ridged restraint, and emotional eating) and height and weight. We examined the predictive value of weight stigma at session 1 on eating behavior and weight gain at session 2. Further, we examined FOF as a mediator of these relationships. In Study 1, we found that FOF significantly mediated the positive relationship between perceived weight stigma and restrained eating behavior (b=.13, CI: .09 to .19). In Study 2, we found that perceived weight stigma predicted weight gain over the 10-week period and that this relationship was mediated by both FOF (b=.31, CI: .03 to .78) and rigid restraint of eating (b=.07, CI: .002 to .28). Flexible restraint and emotional eating behavior were not mediators of the relationship between perceived weight stigma and weight gain. Fear of fat may be one process through which perceptions of weight stigma lead to maladaptive eating behavior and weight gain. Understanding this important process may lead to more effective healthy weight interventions.
