Abstract

BACKGROUND/AIMS: Monitoring overweight prevalence and its trends in Dutch youth is frequently based on self-reported data. The validity of self-reported data especially in young adolescents is not sufficiently known. The purpose of this study is to study the validity of self-reported height and weight in 12- to 13-year-olds, to identify sociodemographic correlates and to explore whether correction factors can be developed to estimate the prevalence of overweight in youth.

METHODS

5,525 12- to 13-year-old pupils in the Rotterdam area filled in a confidential questionnaire on health topics, including their height and weight. In a sub-sample of 499 pupils both self-reported and measured height and weight were available.

RESULTS

Self-reported data led to a considerable underestimation of Body Mass Index and consequently the prevalence of overweight. Underestimation was higher in pupils who regarded themselves as more fat, were of non-Dutch origin and in lower education levels.

CONCLUSION

Self-reported height and weight appeared to be inappropriate to estimate the overweight prevalence in 12- to 13-year-olds, unless the figures were adjusted. Using adjusted self-reported BMI on an individual level is questionable. Actual measurements of height and weight are necessary to draw up valid correction formulas in new samples.

摘要

背景/目的:荷兰青少年超重患病率及其趋势的监测通常基于自我报告的数据。自我报告数据的有效性,尤其是在青少年中的有效性,尚未得到充分了解。本研究的目的是研究12至13岁青少年自我报告的身高和体重的有效性,确定社会人口统计学相关因素,并探讨是否可以制定校正因子来估计青少年超重的患病率。

方法

鹿特丹地区5525名12至13岁的学生填写了一份关于健康主题的保密问卷,包括他们的身高和体重。在499名学生的子样本中,既有自我报告的身高和体重,也有测量的身高和体重。

结果

自我报告的数据导致对体重指数以及超重患病率的严重低估。那些认为自己更胖、非荷兰裔以及教育水平较低的学生中,低估情况更为严重。

结论

自我报告的身高和体重似乎不适用于估计12至13岁青少年的超重患病率,除非对数据进行调整。在个体层面使用调整后的自我报告体重指数存在疑问。要在新样本中制定有效的校正公式,实际测量身高和体重是必要的。
