Abstract

Background/objectives: It is vital to identify children whose weight status means that they may benefit from medical or behavioural support, but adult visual judgements of child weight status are inaccurate, and children are seldom routinely weighed and measured. Consequently, there is a need for validated visual tools for use in training, communication, and interventions relating to child weight.

Methods: This paper presents validation data for a set of innovative photo-realistic colour body size scales depicting boys and girls aged 4-5 and 10-11. Each age- and gender-specific scale consists of 7 figures based on three-dimensional (3D) scans of 388 children to accurately represent the change in body size caused by changing adiposity. To assess scale validity, 238 adult participants (105 men, 132 women, 1 non-binary individual) undertook two tasks: rating figure adiposity using a visual analogue scale and ranking figures in ascending order of adiposity (OSF Reference: gdp9j).

Results: Participants accurately estimated the relative adiposity of each figure, i.e., they were able to tell the difference between figures and correctly rank them by size. This demonstrates scale validity for use in body size tasks. One hundred and fifty-one participants also provided 3-day test-retest data, which demonstrates excellent short-term reliability.

Conclusions: Overall, the MapMe child body size scales provide an anthropometrically accurate, valid, reliable, and usable tool for size-related tasks and communication with adults regarding child weight.

MapMe 体型量表:一套生物统计学上准确、逼真的儿童体型量表的有效性和可靠性。
背景/目的:识别儿童的体重状况至关重要,这意味着他们可能会受益于医疗或行为支持,但成人对儿童体重状况的视觉判断并不准确,而且儿童很少进行常规称重和测量。因此,我们需要经过验证的视觉工具,用于与儿童体重有关的培训、交流和干预:本文介绍了一套新颖的照片逼真彩色体重秤的验证数据,该体重秤描述了 4-5 岁和 10-11 岁男孩和女孩的体重。每个按年龄和性别划分的量表由 7 个数字组成,这些数字基于对 388 名儿童的三维(3D)扫描,以准确地表示因脂肪含量变化而引起的体型变化。为了评估量表的有效性,238 名成年参与者(105 名男性、132 名女性和 1 名非二元个体)进行了两项任务:使用视觉模拟量表对人物的脂肪含量进行评分,以及按照脂肪含量由高到低的顺序对人物进行排序(OSF 参考文献:gdp9j):结果:参与者准确地估计了每个人物的相对脂肪含量,也就是说,他们能够分辨出人物之间的差异,并能正确地按照大小对人物进行排序。这证明了量表在体型任务中的有效性。151 名参与者还提供了为期 3 天的重复测试数据,这表明该量表具有出色的短期可靠性:总的来说,MapMe 儿童体型测量秤为体型相关任务以及与成人就儿童体重进行交流提供了准确、有效、可靠且可用的人体测量工具。

期刊介绍: Children is an international, open access journal dedicated to a streamlined, yet scientifically rigorous, dissemination of peer-reviewed science related to childhood health and disease in developed and developing countries. The publication focuses on sharing clinical, epidemiological and translational science relevant to children’s health. Moreover, the primary goals of the publication are to highlight under‑represented pediatric disciplines, to emphasize interdisciplinary research and to disseminate advances in knowledge in global child health. In addition to original research, the journal publishes expert editorials and commentaries, clinical case reports, and insightful communications reflecting the latest developments in pediatric medicine. By publishing meritorious articles as soon as the editorial review process is completed, rather than at predefined intervals, Children also permits rapid open access sharing of new information, allowing us to reach the broadest audience in the most expedient fashion.
