Higher weight individuals experience frequent weight-related discrimination, which is associated with exercise avoidance. Exercise is a health behavior with multiple physical and mental health benefits and should be accessible to all. The current study examined another factor that might influence exercise in addition to weight stigma: social anxiety (SA). Given the often public nature of exercise, individuals with SA may feel scrutinized when exercising, which may lead to avoidance. This study examined whether SA moderates the relationship between body mass index (BMI) and exercise and whether SA and its interaction with BMI predict exercise behavior after accounting for weight stigma. We administered an online survey to 603 undergraduates (72 % female, 60 % White). SA was not significantly associated with BMI, but it was positively associated with weight stigma and exercise-avoidance motivation and negatively associated with self-reported exercise. SA moderated the relationship between BMI and exercise-avoidance motivation; individuals with higher BMIs were motivated to avoid exercise, but only if they reported higher SA. This interaction predicted exercise-avoidance motivation after accounting for weight stigma and its interaction with BMI. However, SA did not moderate the relationship between BMI and self-reported exercise. SA may be associated with exercise avoidance among higher weight individuals.

体重较高的人经常遭受与体重有关的歧视，这与避免运动有关。运动是一种具有多种身心健康益处的健康行为，应为所有人所接受。当前的研究检查了除体重柱头外还可能影响运动的另一个因素：社交焦虑症（SA）。鉴于锻炼通常是公共性质的，因此SA患者在锻炼时可能会受到严格检查，这可能导致逃避。这项研究检查了SA是否缓解了体重指数（BMI）与运动之间的关系，以及SA及其与BMI的相互作用是否在考虑了体重歧视后预测了运动行为。我们对603名大学生进行了在线调查（女性为72％，白人为60％）。SA与BMI没有显着相关，但它与体重的污名和避免运动的动机呈正相关，与自我报告的运动呈负相关。SA缓解了BMI与避免运动动机之间的关系；BMI较高的人有动机避免运动，但前提是他们报告的SA较高。在考虑了体重柱头及其与BMI的相互作用之后，这种相互作用预测了避免运动的动机。但是，SA并没有减轻BMI与自我报告的锻炼之间的关系。SA可能与体重较高的人避免运动有关。但前提是他们报告的SA更高。在考虑了体重柱头及其与BMI的相互作用之后，这种相互作用预测了避免运动的动机。但是，SA并没有减轻BMI与自我报告的锻炼之间的关系。SA可能与体重较高的人避免运动有关。但前提是他们报告的SA更高。在考虑了体重柱头及其与BMI的相互作用之后，这种相互作用预测了避免运动的动机。但是，SA并没有减轻BMI与自我报告的锻炼之间的关系。SA可能与体重较高的人避免运动有关。
