The socialization of girls to habitually monitor their bodies, via the process of body surveillance, contributes to an increased risk of negative physical and psychological experiences. The present study examined if body surveillance may also contribute to the decrease in physical activity that is observed in girls during adolescence, and if this association is mediated by body shame (operationalized as both experienced and anticipated shame when imagining changes to one’s body in the future). Physically active adolescent girls (n = 206) reported body surveillance at baseline, and measures of experienced and anticpated body shame, and physical activity two years later. Body surveillance was indirectly associated with physical activity via the experience and anticipation of body shame. Specifically, the experience of body shame was associated with lower reported engagement in physical activity (b = −0.13, 95 % CI [−0.23, −0.03]), whereas the anticipation of body shame was associated with higher physical activity (b = 0.07, 95 % CI [0.01, 0.15]), possibly for the purpose of appearance management. Due to the opposing directional effects of experienced versus anticipated body shame, it is important to consider both facets of this emotional experience in understanding how vigilant bodily monitoring impacts physical activity engagement in adolescent girls.

通过身体监测过程使女孩进行社会化以习惯性地监测自己的身体，会增加负面的身心体验的风险。本研究调查了身体监视是否也可能导致青春期女孩体力活动的减少，以及这种关联是否由身体羞耻感所介导（在想象将来改变自己的身体时，既有经验又有预期的羞耻感。 ）。身体活跃的少女（n= 206）报告了基线时的身体监测，以及两年后对经历过的和抗风化的身体羞耻度以及身体活动的测量。身体监视通过经验和对身体羞耻的预期而间接地与体育活动相关。具体而言，身体羞耻的经历与所报告的参与体育活动的参与度较低相关（b = -0.13，95％CI [-0.23，-0.03]），而对身体羞耻的预期与较高的体育活动相关（b= 0.07，95％CI [0.01，0.15]），可能是出于外观管理的目的。由于经历过的和预期发生的身体羞耻感会产生相反的方向性影响，因此在理解警惕的身体监控如何影响青少年的体育活动时，考虑这种情感体验的两个方面非常重要。
