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.
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).
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.
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.
背景/目的：识别那些体重状况表明可能从医学或行为支持中受益的儿童至关重要，但成年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的称重和测量。因此，需要经过验证的视觉工具，用于与儿童体重相关的培训、沟通和干预。
本文展示了一组创新的逼真彩色身体尺寸量表的验证数据，这些量表描绘了4至5岁和10至11岁的男孩和女孩。每个针对特定年龄和性别的量表由7个图形组成，这些图形基于对388名儿童的三维（3D）扫描，以准确呈现因肥胖程度变化而导致的身体尺寸变化。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、1名非二元性别个体）完成了两项任务：使用视觉模拟量表对图形的肥胖程度进行评分，并按照肥胖程度升序对图形进行排序（OSF参考文献：gdp9j）。
参与者准确估计了每个图形的相对肥胖程度，即他们能够区分图形之间的差异，并按大小正确排序。这证明了该量表在身体尺寸任务中的有效性。151名参与者还提供了为期3天的重测数据，这表明其具有出色的短期可靠性。
总体而言，MapMe儿童身体尺寸量表为与身体尺寸相关的任务以及与成年人就儿童体重进行沟通提供了一种在人体测量学上准确、有效、可靠且实用的工具。
