我们研究了身体质量指数（BMI）与积极和消极情感之间的关系，并评估了这种关系是否受到身体健康、体重对身体机能的干扰以及令人痛苦的人际交往的调节（或抑制）。分析基于一个全国性的样本，该样本包含3000多名25岁至74岁的成年人。Ⅱ级（BMI为35 - 39.9）和Ⅲ级（BMI≥40）肥胖与更频繁的消极情感和较不频繁的积极情感相关，即使在控制了人口统计学和社会经济地位特征之后也是如此。然而，在控制了假定的路径变量之后，与正常体重的人相比，Ⅰ级肥胖者报告积极情感的频率显著更高，而超重、Ⅰ级肥胖和Ⅱ级肥胖者报告消极情感的频率显著更低。这些模式在不同种族或性别之间没有显著差异。我们的研究结果表明，体重过重不一定会令人痛苦，然而与肥胖相关的身体和人际交往压力可能会影响一个人的情绪。我们讨论了对政策和实践的影响。（C）2007爱思唯尔有限公司。保留所有权利。
We examined the relationship between body mass index (BMI) and positive and negative affect, and evaluated whether this relationship is mediated (or suppressed) by physical health, intrusiveness of weight on physical functioning, and distressing interpersonal interactions. Analyses were based on a national sample of more than 3,000 adults ages 25 to 74. Class II (BMI 35-39.9) and Class III (BMI >= 40) obesity were associated with more frequent negative affect and less frequent positive affect, even after demographic and socioeconomic status characteristics were controlled. After the purported pathway variables were controlled, however, obese I persons reported significantly more frequent positive affect, while overweight, obese I, and obese II persons reported significantly less frequent negative affect, compared to normal weight persons. These patterns did not differ significantly by race or gender. Our findings suggest that excessive body weight is not necessarily distressing, yet the physical and interpersonal strains associated with obesity may impair one's mood. We discuss the implications for policy and practice. (C) 2007 Elsevier Ltd. All rights reserved.
