Extensive bioelectrical impedance analysis (BIA) data have the potential of health monitoring and the assessment of health risks at the population level. The importance of BIA data lies in their availability and abundance for many countries. In Russia, mass BIA data are generated by the national network of health centers (HCs). Our aim was to describe the structure and capabilities of the updated HCs' BIA database. Upon several requests between 2012 and 2020, 369 HCs representing all Federal districts of Russia and 60 out of 85 Federal subjects in them, submitted raw bioimpedance data which were obtained using the same type of BIA instrument, namely ABC-01 'Medas' (SRC Medas, Russia). After application of strict selection criteria, 2,429,977 BIA measurement records were selected that formed the updated 2010-2019 HCs' database. Various slices of the BIA data are described according to spatiotemporal, demographic and other characteristics. Reference curves of the bioimpedance phase angle according to age and sex are presented. Limitations and prospects for further work are outlined. We believe that, after appropriate sampling, the database can be utilized to study biological, geographical, social and other associations of the bioimpedance and body composition parameters, for generating updated national references, international comparisons and data standardization.
广泛的生物电阻抗分析（BIA）数据具有在人群层面进行健康监测和健康风险评估的潜力。BIA数据的重要性在于其在许多国家的可得性和丰富性。在俄罗斯，大规模BIA数据由国家健康中心（HC）网络生成。我们的目的是描述更新后的HC的BIA数据库的结构和功能。在2012年至2020年期间收到的多次请求后，代表俄罗斯所有联邦区的369个HC以及其中85个联邦主体中的60个提交了使用同一类型的BIA仪器即ABC - 01“Medas”（俄罗斯SRC Medas公司）获得的原始生物阻抗数据。在应用严格的筛选标准后，选取了2,429,977条BIA测量记录，这些记录构成了更新后的2010 - 2019年HC数据库。根据时空、人口统计学和其他特征描述了BIA数据的不同部分。给出了按年龄和性别划分的生物阻抗相角的参考曲线。概述了进一步工作的局限性和前景。我们认为，经过适当抽样后，该数据库可用于研究生物阻抗和身体成分参数的生物学、地理、社会及其他关联，以生成更新后的国家参考标准、进行国际比较和数据标准化。
