背景：成人体重增加的具体潜在原因仍然不确定。目的：目的是确定3种饮食行为指标与成人体重增加和身体质量指数（BMI，单位：kg/m2）之间的关系。设计：使用饮食清单对638名年龄在55-65岁的健康、不吸烟女性进行评估，以了解目前的饮食限制、解除抑制和饥饿情况。此外，受试者报告了他们目前的体重和身高，他们6个年龄段的体重，以及过去10年自愿限制饮食能量的机会。结果：电流去抑制强烈预测体重增加和当前BMI（部分r分别为0.27和0.34，均P < 0.001）。约束和饥饿都不是这两个变量的显著独立预测因子，但抑制解除与体重增加和BMI之间的正相关性被约束减弱（调整混杂变量后，P分别为0.016和0.010）。在报告自愿饮食能量限制水平稳定的女性亚群中，抑制解除也强烈预测体重增加和更高的BMI，抑制与体重增加呈负相关（部分r =-0.17，P = 0.019）。更高的去抑制与更大的成人体重增加和更高的当前BMI密切相关，当去抑制作用高时，饮食限制可能会减弱这种联系。这些研究结果表明，饮食行为在预防成人肥胖症中具有重要作用，需要进一步研究。
Background:The specific underlying causes of adult weight gain remain uncertain.Objective: The objective was to determine the association of 3 measures of eating behavior with weight gain and body mass index (BMI in kg/m(2)) in adults.Design: Current dietary restraint, disinhibition, and hunger were assessed with the use of the Eating Inventory in 638 healthy, nonsmoking women aged 55-65 y. In addition, subjects reported their current weight and height, their weight for 6 age intervals, and chances in voluntary dietary energy restriction over the past 10 y. Current weight and height were validated in 10% of subjects.Results: Current disinhibition strongly predicted weight gain and current BMI (partial r = 0.27 and 0.34, respectively, both P < 0.001). Neither restraint nor hunger was a significant independent predictor of either variable, but the positive associations between disinhibition and both weight gain and BMI were attenuated by restraint (P = 0.016 and 0.010, respectively, after adjustment for confounding variables). In the subpopulation of women who reported a stable level of voluntary dietary energy restriction, disinhibition also strongly predicted weight gain and higher BMI, and restraint was negatively associated with weight gain (partial r = -0.17, P = 0.019).Conclusions: Higher disinhibition is strongly associated with greater adult weight gain and higher cur-rent BMI, and dietary restraint may attenuate this association when disinhibition is high. These findings suggest that eating behavior has an important role in the prevention of adult-onset obesity and that further studies are warranted.
