This study examined what methods people use to determine and interpret their body weight, and what factors are associated with either an underestimation of overweight or an overestimation of a healthy body weight.
The study used self-reported data on weight and height. Data were collected by means of questionnaires (n = 722).
In comparison with unaware overweight individuals, aware overweight respondents had a significantly lower score on comparing their body to that of others and on listening to remarks from others as methods to determine and interpret their body weight. The same was true for respondents with a correct perception of their healthy body weight compared with respondents who overestimated their healthy body weight. Respondents with a correct perception also had a significantly lower score on using the need to change to a different clothing size to determine body weight. Underestimation of overweight was significantly associated with body mass index (BMI), intense physical activity, knowledge of a healthy weight range and body comparison; overestimation of healthy body weight was significantly associated with gender, BMI, weight loss history and media influences.
The study had a cross-sectional design, and therefore no causal relations could be determined. Despite this, the study provided more insight into the way people estimate and judge their body weight.
本研究调查了人们用以确定和解读自身体重的方法，以及与低估超重或高估健康体重相关的因素。
该研究使用了关于体重和身高的自我报告数据。数据通过问卷调查收集（n = 722）。
与未意识到超重的个体相比，意识到超重的受访者在将自己的身体与他人的身体进行比较以及听取他人意见作为确定和解读自身体重的方法方面得分显著较低。与高估自身健康体重的受访者相比，正确认识到自身健康体重的受访者也是如此。正确认识到自身健康体重的受访者在使用因需要更换不同尺码衣服来确定体重方面得分也显著较低。低估超重与体重指数（BMI）、高强度体育活动、对健康体重范围的了解以及身体比较显著相关；高估健康体重与性别、BMI、减肥史和媒体影响显著相关。
该研究采用横断面设计，因此无法确定因果关系。尽管如此，该研究为人们估计和判断自身体重的方式提供了更多见解。
