目的研究英国公众对超重的看法在八年内的变化。设计比较1999年和2007年人口调查的自我感知体重数据。设置英国两个代表性样本的家庭调查。1999年的参与者为853名男子和944名妇女，2007年为847名男子和989名妇女。主要结果测量参与者被要求报告他们的体重和身高，并将他们的身体尺寸从“体重过轻”到“肥胖”进行分类。结果自我报告的体重随着时间的推移显着增加，但人们认为自己超重的体重也显着增加。1999年，81%的超重参与者正确地识别出自己超重，而2007年为75%，这表明自我诊断超重的敏感性下降。尽管媒体和健康运动旨在提高人们对健康体重的认识，但越来越多的超重者未能认识到他们的体重是一个值得关注的问题。这使得他们不太可能将控制体重的呼吁视为个人相关。
Objectives To examine changes in public perceptions of overweight in Great Britain over an eight year period. Design Comparison of data on self perceived weight from population surveys in 1999 and 2007. Setting Household surveys of two representative samples in Great Britain. Participants 853 men and 944 women in 1999, and 847 men and 989 women in 2007. Main outcome measures Participants were asked to report their weight and height and classify their body size on a scale from “very underweight” to “obese.” Results Self reported weights increased dramatically over time, but the weight at which people perceived themselves to be overweight also rose significantly. In 1999, 81% of overweight participants correctly identified themselves as overweight compared with 75% in 2007, demonstrating a decrease in sensitivity in the self diagnosis of overweight. Conclusions Despite media and health campaigns aiming to raise awareness of healthy weight, increasing numbers of overweight people fail to recognise that their weight is a cause for concern. This makes it less likely that they will see calls for weight control as personally relevant.
