目标：描述BMI和感知体重状态之间的关系，并确定体重状态评估不足与人口统计学特征、自我报告的一般健康状况以及与体重相关的感知健康风险之间的关系。方法和程序：在2004年的Styles调查中，3,888名美国成年参与者描述了他们目前的体重状况（体重过轻，大约正确，轻微超重，非常超重），我们将其与自我报告的BMI进行比较，以确定一致性。我们使用多变量逻辑回归来评估体重低估和感兴趣的特征之间的关联。结果：在BMI >= 25的人群中，女性比男性更容易认识到自己的超重状态（轻微或非常超重; 93.0%的女性对73.5%的男性）以及他们超重的程度：70.4%的肥胖女性和49.5%的肥胖男性称自己超重。在超重和肥胖的男性和女性中，对当前体重作为健康风险的不同意与对体重的低估有关。与评估不足相关的其他因素包括超重女性的教育和种族/民族;超重男性的种族/民族;肥胖女性的家庭收入和自评健康;以及肥胖男性的自评健康（P < 0.05）。讨论：虽然大多数肥胖的参与者承认他们超重，但他们中的许多人，特别是男性，没有意识到他们超重的程度。如果公共卫生信息除了强调与超重有关的健康风险之外，还针对目标受众进行专门定制，则可能会更有效。
objectives: To describe the relationship between BMI and perceived weight status and to determine how underassessment of weight status is associated with demographic characteristics, self-reported general health, and perceived health risk in relation to one's body weight.Methods and Procedures: In the 2004 Styles surveys, 3,888 US adult participants described their current weight status (underweight, about right, slightly overweight, very overweight), which we compared with self-reported BMI in order to determine concordance. We used multivariable logistic regression to evaluate associations between underassessment of body weight and characteristics of interest.Results: Among persons with a BMI >= 25, women were more likely than men to recognize their overweight status (slightly or very overweight; 93.0% of women vs. 73.5% of men) and the extent to which they were overweight: 70.4% of obese women vs. 49.5% of obese men described themselves as very overweight. Among the overweight and obese of both sexes, disagreement with regard to current weight as a health risk was associated with underassessment of weight. Additional factors associated with underassessment were education and race/ethnicity among overweight women; race/ethnicity among overweight men; household income and self-rated health among obese women; and self-rated health among obese men (P < 0.05).Discussion: While most of the obese participants recognized that they were overweight, many of them, particularly among the men, did not realize the extent to which they were overweight. Public health messages may be more effective if they are specifically tailored to target audiences, besides emphasizing the health risks associated with excess body weight.
