To examine changes in the prevalence of overweight and weight misperception among overweight Danes from 1995 to 2008, and to identify factors associated with weight misperception.
Cross-sectional studies, in which data on self-reported weight, height and self-perception of overweight status were obtained through face-to-face interviews. 'Overweight' includes obesity. Weight misperception was defined as overweight individuals who did not perceive themselves as overweight. The χ 2 test was used to analyse changes over time and multiple logistic regression analysis was applied to identify factors associated with weight misperception.
The Danish National Survey of Diet and Physical Activity in three periods: 1995, 2000-2004 and 2005-2008.
A random sample of 9623 Danes aged 15-75 years.
The prevalence of overweight increased in men and women from 1995 to 2005-2008 (from 35·1 % to 43·0 %, P < 0·001). Concurrently, there was a reduction in the proportion of overweight men (from 77·5 % to 71·4 %, P = 0·001) and women (from 54·8 % to 51·9 %, P = 0·24) who misperceived their weight. Factors associated with weight misperception were 'never intend to eat healthily' (men), high levels of leisure-time physical activity, 'very good/excellent' self-rated health and survey year (higher misperception in 2000-2004 than 2005-2008; P < 0·05).
The increase in overweight from 1995 to 2005-2008 was accompanied by a reduction in the proportion of overweight men misperceiving their weight. This may indicate that more men see overweight as a personally relevant health problem. Our findings also suggest that overweight individuals who are more physically active and have better self-rated health may not consider their excess weight a health problem.
检测丹麦超重人群中体重超重和体重感知错误的流行率在 1995 年至 2008 年间的变化，并确定与体重感知错误相关的因素。
通过面对面访谈获得自我报告的体重、身高和自我超重状态数据的横断面研究。“超重”包括肥胖。体重感知错误被定义为超重个体没有感知到自己超重。使用 χ 2 检验分析随时间的变化，应用多因素逻辑回归分析确定与体重感知错误相关的因素。
丹麦全国饮食和体力活动调查在三个时期进行：1995 年、2000-2004 年和 2005-2008 年。
年龄在 15-75 岁之间的 9623 名丹麦人随机样本。
1995 年至 2005-2008 年间，男性和女性的超重流行率增加（从 35.1%增加到 43.0%，P<0.001）。同时，超重男性（从 77.5%减少到 71.4%，P=0.001）和女性（从 54.8%减少到 51.9%，P=0.24）中错误感知体重的比例减少。与体重感知错误相关的因素包括“从不打算健康饮食”（男性）、高水平的休闲时间体力活动、“非常好/优秀”的自我评估健康状况和调查年份（2000-2004 年比 2005-2008 年的错误感知率更高；P<0.05）。
1995 年至 2005-2008 年间超重的增加伴随着超重男性错误感知体重比例的减少。这可能表明更多的男性将超重视为个人相关的健康问题。我们的研究结果还表明，体力活动水平较高、自我评估健康状况较好的超重个体可能不认为自己的体重超标是一个健康问题。
