Bioelectrical impedance analysis (BIA) requires a high degree of standardisation in order to ensure valid and reproducible impedance measurements. The overall aim of this review was to study the degree to which BIA papers conducted in healthy paediatric populations (aged 0-17 years) were standardised.
Literature was identified on the basis of a systematic search of internationally-recognised electronic databases and hand searching of the reference lists of the included papers in order to identify additional relevant papers. The review was limited to lead-type BIA devices for whole-body, segmental- and focal impedance measurements. In total, 71 papers published between 1988 and 2016 were included. To evaluate the degree of standardisation of the papers, a recently published review detailing critical factors that may impact on BIA measurements in children was used as a model for structuring and extracting data.
There was a general lack of BIA standardisation, or its reporting, in the papers under review, which hinders comparison of data between studies and could potentially lead to erroneous measurements.
If the BIA technique should be accepted clinically for routine use in paediatric populations, there is a need for an increased focus on the importance of improved standardisation and its reporting in future studies. Consequently, this review contains recommendations for performing and reporting BIA measurements in a standardised manner.
生物电阻抗分析（BIA）需要高度标准化，以确保获得有效且可重复的阻抗测量结果。本综述的总体目的是研究在健康儿童人群（0至17岁）中进行的BIA研究的标准化程度。
通过系统检索国际认可的电子数据库，并人工查阅纳入论文的参考文献列表以识别其他相关论文来确定文献。该综述仅限于用于全身、分段和局部阻抗测量的铅型BIA设备。总共纳入了1988年至2016年间发表的71篇论文。为了评估论文的标准化程度，以最近发表的一篇详细阐述可能影响儿童BIA测量的关键因素的综述作为构建和提取数据的模型。
在所审查的论文中，普遍缺乏BIA标准化或其报告，这阻碍了研究之间的数据比较，并可能导致错误的测量结果。
如果BIA技术要在临床上被接受用于儿科人群的常规使用，未来的研究需要更加关注改进标准化及其报告的重要性。因此，本综述包含了以标准化方式进行和报告BIA测量的建议。
