Using a cross-sectional survey from a relatively large sample of adult women, we examined the relationships of objectified body consciousness (OBC) to physical activity levels, dietary intake, and self-efficacy to control one's weight through exercise or healthy eating. OBC accounted for a small, statistically significant amount of variation in moderate and vigorous physical activity. Self-efficacy partially mediated the weak relationship between control beliefs and vigorous physical activity. Differences in OBC between weight control motivation groups (those trying to lose weight vs. maintain weight) and body mass index levels were found. Findings indicate a complex interaction of OBC with health behavior, having associations with restrained and disordered eating, but little to no relationship with physical activity and dietary food choices.

女性的客观身体意识、身体活动和膳食摄入量

使用来自相对较大的成年女性样本的横断面调查，我们检查了客观化身体意识 (OBC) 与身体活动水平、饮食摄入量以及通过运动或健康饮食控制体重的自我效能之间的关系。OBC 在中等强度和剧烈的身体活动中占了很小的、具有统计意义的变化量。自我效能在一定程度上调节了控制信念与剧烈体育活动之间的弱关系。发现体重控制动机组（那些试图减肥与保持体重的组）和体重指数水平之间的 OBC 差异。研究结果表明 OBC 与健康行为之间存在复杂的相互作用，与节制和无序饮食有关，但与身体活动和饮食选择几乎没有关系。
