目的评估2007年和2012年英国成年肥胖人口中使用“肥胖”和“非常超重”来描述自己体重的比例，并找出与更准确的体重认知相关的因素。设计分析来自两个基于人群的调查的体重感知数据。在英国进行的背景人口调查。参与者调查受访者(N=657)，他们自己报告的体重和身高将他们归入肥胖类别：身体质量指数(BMI)≥30。主要结果是使用“肥胖”和“非常超重”这两个术语来衡量自我认同。结果无论是女性(2007年为13%，2012年为11%)和男性(2007年为4%，2012年为7%)，肥胖成年人选择“肥胖”来描述自己的体型的比例都很低，而且没有显著变化。女性对超重程度的认可度大幅下降，从2007年的50%降至2012年的34%。男性的这一比例变化不大(2007年为27%，2012年为23%)。拥有较高的BMI，并能够确定肥胖的BMI阈值，与自我认定为肥胖或非常超重有关。结论英国大多数成年肥胖人口并不认为自己肥胖，甚至不认为自己超重。由于缺乏对体重状况的认识，解决肥胖问题的公共卫生倡议可能会受到阻碍。重要的是要了解提高肥胖者对体重状况的个人认识的举措是否可以促进有益的行为改变，以及卫生专业人员在提高肥胖症患者对体重状况的认识方面可以发挥什么作用。
Objectives To assess the proportion of the adult obese population in Great Britain who would describe their weight using the terms ‘obese’ and ‘very overweight’ in 2007 and 2012, and identify factors associated with more accurate weight perceptions. Design Analysis of weight perception data from two population-based surveys. Setting Population surveys conducted in Great Britain. Participants Survey respondents (N=657) whose self-reported weight and height placed them in the obese category: body mass index (BMI) ≥30. Primary outcome measure Self-identification using the terms ‘obese’ and ‘very overweight’. Results The proportion of obese adults selecting the term ‘obese’ to describe their body size was very low in both women (13% in 2007 and 11% in 2012) and men (4% in 2007 and 7% in 2012) and did not change significantly. Recognition of a substantial degree of overweight (as indexed by endorsement of either of the terms ‘obese’ or ‘very overweight’) declined substantially in women, from 50% in 2007 to 34% in 2012. It was not significantly changed in men (27% in 2007 and 23% in 2012). Having a higher BMI, and being able to identify the BMI threshold for obesity were associated with self-identifying as obese or very overweight. Conclusions The majority of the adult obese population of Great Britain do not identify themselves as either ‘obese’ or even ‘very overweight’. Public health initiatives to tackle obesity are likely to be hampered by this lack of recognition of weight status. It is important to understand whether moves to increase personal awareness of weight status in the obese population can facilitate beneficial behaviour change, and what role health professionals can play in increasing awareness of weight status in obese patients.
