To study how waist circumference (WC) relates to body perception in adolescent girls and to maternal perception of the girl's body size.
Three hundred and four girls, 11-18 years, were measured for height, weight and WC. 294 girls provided self-report data on weight, height and body image before anthropometric measurements. Paired data from 237 girls and mothers on perception of the girls' body size were collected.
In girls, self-reported weight indicated awareness of actual body size. The girls' body perception showed an overestimation of body size relative to international reference values for body mass index (BMI) (p < 0.05), but not for WC. Girls' body perception exceeded that of their mothers (p < 0.05). Maternal perception agreed better than the girls' perception with international reference values for BMI (p < 0.05). No significant difference between mothers and girls were found concerning agreement of body perception with international reference values for WC.
WC rather than BMI agrees with perception of body size, possibly due to its relation to abdominal fat at different ages. For effective prevention and treatment programmes for weight-related health problems among adolescent girls, we recommend measuring WC to diminish the discrepancy between measured and perceived body size.
研究腰围（WC）与青春期女孩身体认知以及母亲对女孩体型认知之间的关系。
对304名11至18岁的女孩进行身高、体重和腰围测量。294名女孩在人体测量前提供了关于体重、身高和身体形象的自我报告数据。收集了237名女孩及其母亲对女孩体型认知的配对数据。
在女孩中，自我报告的体重表明其对实际体型有认知。女孩的身体认知显示，相对于国际体重指数（BMI）参考值，其对体型存在高估（p<0.05），但对腰围不存在高估。女孩的身体认知超过了其母亲（p<0.05）。母亲的认知与国际BMI参考值的一致性优于女孩（p<0.05）。在身体认知与国际腰围参考值的一致性方面，母亲和女孩之间未发现显著差异。
腰围而非BMI与体型认知相符，这可能是由于其与不同年龄段腹部脂肪的关系。为有效预防和治疗青春期女孩与体重相关的健康问题，我们建议测量腰围以减少测量体型与感知体型之间的差异。
