To examine associations between defined weight expectations and anthropometric profile and to identify psychological and eating behavioral factors that characterize women having more realistic weight expectations.
A nonrandom sample of 154 overweight/obese women completed the 'Goals and Relative Weight Questionnaire', which assessed four weight expectations: (1) dream weight (whatever wanted to weight); (2) happy weight (would be happy to achieve); (3) acceptable weight (could accept even if not happy with it); and (4) disappointed weight (would not view as a successful achievement). Psychological assessments evaluated dysphoria, self-esteem, satisfaction with one's body (i.e., body esteem) and weight-related quality of life. The 'Three-Factor Eating Questionnaire' assessed eating behaviors: (1) cognitive dietary restraint (control of food intake), (2) disinhibition (overconsumption of food with a loss of control), and (3) susceptibility to hunger (food intake in response to feelings and perceptions of hunger).
Women's expectations for their dream (60.6+/-6.0 kg), happy (65.2+/-6.4 kg) and acceptable (67.9+/-6.8 kg) weights corresponded to higher percentages of weight loss (24.2+/-6.6% or 19.8+/-7.1 kg, 18.6+/-5.8% or 15.2+/-6.0 kg and 15.2+/-5.7% or 12.6+/-5.8 kg, respectively) than goals recommended for overweight individuals. Defined weight expectations were positively associated with current weight and body mass index (BMI; 0.37 < or = r < or = 0.85; P<0.0001). When women were matched one by one for their current BMI, but showing different happy BMI, women with a more realistic happy BMI were older (P=0.03) and were characterized by a greater satisfaction towards body weight (P=0.04), a higher score for flexible restraint (P=0.003) and a lower score for susceptibility to hunger (P=0.02) than women with a less realistic happy BMI.
These findings suggest that having more realistic weight expectations is related to healthier psychological and eating behavioral characteristics.
研究设定的体重期望与人体测量学特征之间的关联，并确定具有更现实体重期望的女性所具有的心理和饮食行为因素。
对154名超重/肥胖女性的非随机样本进行了“目标与相对体重问卷”的调查，该问卷评估了四种体重期望：（1）理想体重（任何想要的体重）；（2）满意体重（达到后会感到满意）；（3）可接受体重（即使不满意也能接受）；（4）失望体重（不会视为成功达成的体重）。心理评估包括烦躁不安、自尊、对自己身体的满意度（即身体自尊）以及与体重相关的生活质量。“三因素饮食问卷”评估了饮食行为：（1）认知性饮食限制（对食物摄入的控制）；（2）去抑制作用（在失去控制的情况下过度进食）；（3）饥饿易感性（因饥饿感和饥饿认知而进食）。
女性对其理想体重（60.6±6.0千克）、满意体重（65.2±6.4千克）和可接受体重（67.9±6.8千克）的期望对应的体重减轻百分比（分别为24.2±6.6%或19.8±7.1千克、18.6±5.8%或15.2±6.0千克、15.2±5.7%或12.6±5.8千克）高于超重个体推荐的目标。设定的体重期望与当前体重和体重指数（BMI；0.37≤r≤0.85；P<0.0001）呈正相关。当根据当前BMI对女性进行一对一匹配，但她们的满意BMI不同时，与满意BMI不太现实的女性相比，满意BMI更现实的女性年龄更大（P=0.03），对体重的满意度更高（P=0.04），灵活限制得分更高（P=0.003），饥饿易感性得分更低（P=0.02）。
这些发现表明，拥有更现实的体重期望与更健康的心理和饮食行为特征相关。
