目标 对个人体重状况的无根据低估和高估可能会妨碍体重维持行为。本研究报告了低估和高估个人体重状况的相关性以及与体重维持意图和自我报告行动的关系。设计比较代表不同人群的三项横断面调查。受试者调查1：1694名13-19岁的青少年；1694名13-19岁的青少年。调查2：979名25-35岁非肥胖成年人；调查 3：617 名 21-62 岁的成年人。测量 自填书面问卷（调查 1 和 3）和电话问卷（调查 2）；自我报告的体重指数、自我评估的体重状况、避免体重增加或减肥的意图和自我报告的行动、性别、年龄、教育和种族背景。根据 BMI 和自评体重状况，将受访者分为对个人体重状况持现实态度的人或低估和高估自己体重状况的人。 结果 三个调查人群中的大多数受访者对自己的体重状况持现实态度。女性中体重状况始终更容易被高估，而男性、老年受访者和少数民族受访者中体重状况更容易被低估。与基于体重指数的体重状况相比，自评体重状况与避免体重增加的意图和自我报告行动的相关性更强。 结论 研究人群的相关比例低估或高估了自己的体重状况。高估个人体重状况可能会导致不必要的体重维持行为，而低估可能会导致缺乏避免体重进一步增加的动力。
Objectives Unwarranted underestimation and overestimation of personal weight status may prevent weight maintenance behaviour. The present study reports on correlates of under- and overestimation of personal weight status and the association with weight maintenance intentions and self-reported action.Design Comparison of three cross-sectional surveys, representing different population groups.Subjects Survey 1: 1694 adolescents 13-19 years of age; survey 2: 979 nonobese adults 25-35 years of age; survey 3: 617 adults 21-62 years of age.Measurements Self-administered written questionnaires (surveys 1 and 3) and telephone-administered questionnaires (survey 2); self-reported BMI, self-rated weight status, intentions and self-reported actions to avoid weight gain or to lose weight, sex, age, education and ethnic background. Respondents were classified as people who are realistic about personal body weight status or people who under- and overestimate their body weight status, based on BMI and self-rated weight status.Results Most respondents in the three survey populations were realistic about their weight status. Overestimation of weight status was consistently more likely among women, whereas underestimation was more likely among men, older respondents and respondents from ethnic minorities. Self-rated weight status was a stronger correlate of intentions and self-report actions to avoid weight gain than weight status based on Body Mass Index.Conclusions Relevant proportions of the study populations underestimated or overestimated their bodyweight status. Overestimation of personal weight status may lead to unwarranted weight maintenance actions, whereas underestimation may result in lack of motivation to avoid further weight gain.
