To examine changes in public perceptions of overweight in Great Britain over an eight year period.
Comparison of data on self perceived weight from population surveys in 1999 and 2007.
Household surveys of two representative samples in Great Britain.
853 men and 944 women in 1999, and 847 men and 989 women in 2007.
Participants were asked to report their weight and height and classify their body size on a scale from "very underweight" to "obese."
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.
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.
研究八年间英国公众对超重认知的变化。
比较1999年和2007年人口调查中自我认知体重的数据。
英国两个代表性样本的家庭调查。
1999年有853名男性和944名女性，2007年有847名男性和989名女性。
要求参与者报告自己的体重和身高，并按照从“非常体重过轻”到“肥胖”的等级对自己的体型进行分类。
随着时间推移，自我报告的体重显著增加，但人们认为自己超重的体重标准也显著上升。1999年，81%的超重参与者能正确认定自己超重，而2007年这一比例为75%，表明超重自我诊断的敏感性有所下降。
尽管有媒体宣传和健康运动旨在提高对健康体重的认识，但越来越多的超重者并未意识到自己的体重值得关注。这使得他们不太可能认为控制体重的呼吁与自己相关。
