目的：为了研究的影响，非响应自我报告的体重和身高的健康问卷的估计obesity.Methods和程序：一个横断面的人口为基础的健康调查，在社区的瓦拉与16,009居民（2002年）在瑞典西南部。在30-74岁的居民中按性别和年龄分层随机选择的参与者被连续邀请到当地卫生保健中心进行健康检查，包括两次访问。在第一次访视时通过健康问卷获得关于体重和身高的自我报告信息，并在第二次访视时测量关于这两个变量的信息。对于本研究，1，809例受试者（904例男性和905例女性）完成了两次访视（参与率81%），护士在访视2时测量了所有受试者的体重和身高。参与者没有自我报告的体重和/或身高在第一次访问被定义为non-responders.Results：男性和女性的非应答者显着年龄大于应答者。女性无应答者的BMI（29.8 +/- 5.8 kg/m2）显著高于女性应答者（26.6 +/- 5.3 kg/m2）（P < 0.001）。在男性中没有类似的发现。无应答者比应答者更容易肥胖，男性（比值比（OR）2.06，95%置信区间（CI）1.03-4.11）和女性（OR 2.24，95% CI 1.25-4.02）。在描述人群中肥胖的准确患病率时，测量的体重和身高是首选。
Objective: To examine the impact of non-response to self-reported body weight and height in health questionnaires for the estimation of obesity prevalence.Methods and Procedures: A cross-sectional population-based health survey in the community of Vara with 16,009 residents ( in year 2002) in South-western Sweden. Participants randomly selected in strata by sex and age among residents being 30-74 years old were consecutively invited to the local health care center for a health examination, including two visits. Self-reported information on body weight and height were obtained by health questionnaires at the first visit, and measured information on both variables at the second visit. For this study 1,809 subjects ( 904 men and 905 women) completed both visits ( participation rate 81%), and a nurse measured body weight and height of all at visit two. Participants not self-reporting body weight and/or height at the first visit were defined as non-responders.Results: Both male and female non-responders were significantly older than responders. Female non-responders had significantly higher BMI ( 29.8 +/- 5.8 kg/m(2)) than female responders ( 26.6 +/- 5.3 kg/m(2)), ( P < 0.001). No similar findings were seen in men. Non-responders were more likely to be obese than responders both in men ( odds ratio ( OR) 2.06, 95% confidence interval (CI) 1.03-4.11) and in women ( OR 2.24, 95% CI 1.25-4.02).Discussion: Non-responders to self-reported body weight and height in health questionnaires contribute to the underestimation of obesity. Measured body weight and height are to prefer when describing the accurate prevalence of obesity in populations.
