行为和人格特征可能是共同调节体重的因素。本研究探讨了身体质量指数（BMI）与自我报告的行为和人格测量之间的关系。这些测量包括饮食行为（基于三因素饮食问卷），对奖罚的敏感性（基于行为抑制系统/行为激活系统（BIS/BAS）量表）和自我报告的冲动性（基于Barratt冲动性量表-11）。我们发现节制饮食和身体质量指数之间呈倒u型关系。这种关系被去抑制饮食的程度所缓和。与饮食行为无关，BIS和BAS反应性与BMI存在性别差异，男性呈负相关，女性呈正相关。总之，饮食行为和BIS/BAS反应性占BMI差异的很大比例（男性：25%，女性：32%）。自我报告的冲动与BMI之间没有直接关系。综上所述，我们的研究结果表明，研究因素与BMI之间存在线性和非线性关系。此外，体重状况不仅与饮食行为（认知约束和去抑制）有关，还与与饮食环境无关的人格因素（BIS/BAS）有关。重要的是，这些关系在男女之间是不同的。
Behavioral and personality characteristics are factors that may jointly regulate body weight. This study explored the relationship between body mass index (BMI) and self-reported behavioral and personality measures. These measures included eating behavior (based on the Three-Factor Eating Questionnaire), sensitivity to reward and punishment (based on the Behavioral Inhibition System/Behavioral Activation System (BIS/BAS) scales) and self-reported impulsivity (based on the Barratt Impulsiveness Scale-11). We found an inverted U-shaped relationship between restrained eating and BMI. This relationship was moderated by the level of disinhibited eating. Independent of eating behavior, BIS and BAS responsiveness were associated with BMI in a gender-specific manner with negative relationships for men and positive relationships for women. Together, eating behavior and BIS/BAS responsiveness accounted for a substantial proportion of BMI variance (men: ∼25%, women: ∼32%). A direct relationship between self-reported impulsivity and BMI was not observed. In summary, our results demonstrate a system of linear and non-linear relationships between the investigated factors and BMI. Moreover, body weight status was not only associated with eating behavior (cognitive restraint and disinhibition), but also with personality factors not inherently related to an eating context (BIS/BAS). Importantly, these relationships differ between men and women.
