Negative weight-related experiences and internalized weight stigma have been associated with poorer body image and reduced physical activity in adolescents. However, exploring body image and physical activity as discrete weight stigma outcomes fails to consider the theoretically- and empirically-supported covariation between the two. The present study tested a novel integrated model of the associations among negative weight-related experiences and internalized weight stigma (via weight-related distress), body image (shame, authentic pride, body appreciation), and physical activity. Canadian adolescents (N = 311, M ± SD = 16.00 ± 1.01, 75.5% girls) completed a cross-sectional self-report survey. A structural equation model with maximum likelihood robust estimation was tested. Higher negative weight-related experiences were indirectly associated with poorer body image (i.e., higher shame; lower authentic pride and appreciation) through higher weight-related distress. Authentic pride was associated with moderate-to-vigorous physical activity. Higher negative weight-related experiences were indirectly associated with lower physical activity through higher weight-related distress and lower body-related authentic pride. These findings elucidate targetable individual mechanisms and larger systems that could improve body image and foster physical activity among adolescents who encounter negative weight-related experiences and internalized weight stigma.
与体重相关的负面经历和内化的体重污名与青少年较差的身体形象和较少的体育活动有关。然而，将身体形象和体育活动作为离散的体重污名结果进行探究，未能考虑到两者之间在理论和实证上均得到支持的协变关系。本研究测试了一个新颖的综合模型，该模型涉及与体重相关的负面经历和内化的体重污名（通过与体重相关的困扰）、身体形象（羞耻感、真实自豪感、身体欣赏）和体育活动之间的关联。加拿大青少年（N = 311，M ± SD = 16.00 ± 1.01，75.5% 为女孩）完成了一项横断面自我报告调查。测试了一个采用最大似然稳健估计的结构方程模型。与体重相关的负面经历越多，通过更高的与体重相关的困扰，与较差的身体形象（即更高的羞耻感；更低的真实自豪感和欣赏）间接相关。真实自豪感与中度至剧烈的体育活动相关。与体重相关的负面经历越多，通过更高的与体重相关的困扰和更低的与身体相关的真实自豪感，与更低的体育活动间接相关。这些发现阐明了可靶向的个体机制和更大的系统，这些机制和系统可以改善身体形象，并促进那些遭遇与体重相关的负面经历和内化体重污名的青少年进行体育活动。
