A substantial proportion of individuals with overweight or obesity perceive themselves as 'too heavy' relative to 'about right'. Perceiving one's weight as 'too heavy' is associated with lower levels of physical activity and higher levels of sedentary behaviour. However, the mechanisms underpinning the associations between weight perception and lifestyle behaviours have not been identified. Based on theoretical tenets and empirical evidence, the self-conscious emotions of shame and guilt may mediate these associations.
Participants were young adults ( = 618, M = 24.0 ± .6 years) who provided data on weight, weight perception, body-related shame and guilt, physical activity and screen time.
Mediation analyses using the PROCESS macro indicated that shame and guilt significantly mediated the relationships between weight perception and physical activity and shame significantly mediated the relationship between weight perception and screen time.
These findings provide preliminary evidence that self-conscious emotions may be mechanisms by which weight perception influences physical activity and sedentary behaviour in young adults. However, longitudinal investigations of this mechanism are needed.
相当一部分超重或肥胖的人认为自己相对于“正常体重”来说“太重了”。将自己的体重视为“太重”与较低的身体活动水平和较高的久坐行为水平相关。然而，体重认知与生活方式行为之间关联的潜在机制尚未明确。基于理论原则和实证证据，羞耻和内疚等自我意识情绪可能介导了这些关联。
参与者为年轻成年人（n = 618，M = 24.0 ± 0.6岁），他们提供了有关体重、体重认知、与身体相关的羞耻和内疚、身体活动及屏幕使用时间的数据。
使用PROCESS宏进行的中介分析表明，羞耻和内疚显著介导了体重认知与身体活动之间的关系，羞耻显著介导了体重认知与屏幕使用时间之间的关系。
这些发现提供了初步证据，表明自我意识情绪可能是体重认知影响年轻成年人身体活动和久坐行为的机制。然而，需要对这一机制进行纵向研究。
