目的：检验自我报告的体重和身高以及由此产生的体重指数（BMI）的有效性，并探讨人口统计学、社会经济学和健康相关因素与自我报告的体重和身高偏倚之间的关系，以确定最有可能出现偏倚的人群。设计：前瞻性队列研究。来自GAZEL队列的7350名中年受试者，5445名男性和1905名女性，自1989年以来一直接受随访，并在法国国家公司Electricite De France-Get De France（EDF-GDF）从事各种职业。自我报告的体重和身高是根据每年邮寄的问卷调查的信息，测量的体重和身高，在这里作为真实值，由职业医生提供1994年至1997年。性别，年龄，婚姻状况，教育，职业，缺血性心脏病史，心血管危险因素的治疗是从邮寄的问卷或从公司的人事和医疗部门提供的数据获得的。结果：测量值和自我报告的值之间有很强的相关性，但自我报告的体重和身高显示显着的系统误差。男性（0.54 kg）和女性（0.85 kg）的体重被显著低估，男性（0.38 cm）和女性（0.40 cm）的身高被高估。这些偏差导致BMI被显着低估（男性和女性分别为0.29和0.44 kg/m（2））。因此，超重的流行率，定义为女性BMI> 26.9 kg/m2，男性BMI> 27.2 kg/m2，也被低估了，男性为13%，女性为17%。与偏见在自我报告的体重和身高的五个因素是：超重状态，结束数字的偏好，年龄，教育水平和occupation.CONCLUSION：这些研究结果表明，自我报告的体重和身高应谨慎对待，因为偏见导致超重和肥胖的错误分类，特别是在某些部分的人口。
OBJECTIVE: To examine the validity of self-reported weight and height and the resulting body mass index (BMI), and to explore the associations between demographic, socioeconomic, and health-related factors on the one hand and bias in self-reported weight and height on the other, in order to determine the groups most likely to exhibit bias.DESIGN: Prospective cohort study.SUBJECTS: 7350 middle-aged subjects, 5445 men and 1905 women, from the GAZEL cohort, who have been followed up since 1989 and work at the French national company Electricite De France-Get De France (EDF-GDF) in various occupations.MEASUREMENTS: Self-reported weight and height were based on information from yearly mailed questionnaires, and measured weight and height, used here as true values, were provided by occupational physicians from 1994 to 1997. Sex, age, marital status, education, occupation, history of ischemic heart disease, and treatment for cardiovascular risk factors were obtained from the mailed questionnaires or from data provided by the Company's personnel and medical departments.RESULTS: Strong correlations were found between measured and self-reported values, but self-reported weight and height displayed significant systematic errors. Weight was significantly underestimated for men (0.54 kg) and for women (0.85 kg), and height overestimated for men (0.38 cm) and women (0.40 cm). These biases led to significant underestimations of BMI (0.29 and 0.44 kg/m(2) for men and women respectively). Consequently, the prevalence of overweight, defined as BMI > 26.9 kg/m(2) for women and BMI > 27.2 kg/m(2) for men, was also underestimated, by 13% for men and 17% for women. The five factors associated with bias in self-reported weight and height were: overweight status, end-digit preference, age, educational level and occupation.CONCLUSION: These findings suggest that self-reported weight and height should be treated with caution, because of biases leading to misclassification for overweight and obesity, especially in certain segments of the population.
