The current study examined BMI and body image dissatisfaction as predictors of physical and mental health-related quality of life (HRQL) and psychosocial functioning in a sample of 414 undergraduate students (mean age=21.5, SD=4.9; mean BMI=23.6, SD=5.2). In men and women, higher BMI was correlated with body image dissatisfaction and physical HRQL, but not with any measures of psychosocial functioning, whereas higher body image dissatisfaction was associated with poorer physical HRQL and psychosocial functioning. Furthermore, body image dissatisfaction was observed to mediate the relationship between BMI and physical HRQL in men and women. Interestingly, in this model, higher BMI predicted increased self-esteem. These findings suggest that body image dissatisfaction may be an important target for health interventions.
本研究以 414 名大学生为样本（平均年龄=21.5，标准差=4.9；平均 BMI=23.6，标准差=5.2），考察了 BMI 和身体意象不满作为身体健康相关生活质量（HRQL）和心理社会功能的预测因子。在男性和女性中，较高的 BMI 与身体意象不满和身体健康 HRQL 相关，但与任何心理社会功能测量无关，而较高的身体意象不满与较差的身体健康 HRQL 和心理社会功能相关。此外，身体意象不满被观察到在男性和女性的 BMI 和身体健康 HRQL 之间起中介作用。有趣的是，在这个模型中，较高的 BMI 预测自尊心增强。这些发现表明，身体意象不满可能是健康干预的一个重要目标。
