Абсолютное количество общей, внеклеточной и внутриклеточной воды организма напрямую зависит от габаритных размеров и компонентного состава тела, поэтому для оценки статуса гидратации организма используют относительные показатели водных секторов организма (в процентах от массы тела) и коэффициенты распределения воды в организме: ВнекВ/ОВО и ВнекВ/ВнукВ.Цель. Определить, в чем состоит разница оценки распределения воды и статуса гидратации организма с помощью биоимпедансных анализаторов различных модификаций и фирм-производителей.Результаты и обсуждение. При использовании для оценки статуса гидратации и оценки распределения воды в организме биоимпедансных анализаторов следует иметь в виду, что они имеют отличные друг от друга нормативные значения индексов ВнекВ/ОВО и ВнекВ/ВнукВ. Полученные значения следует трактовать только согласно нормативам, представленным в инструкциях пользователя к тому анализатору, на котором была проведена оценка. Главные отличия оценки разными анализаторами состоят в том, что нормальные значения индекса увеличиваются с возрастом исследуемого при измерении анализаторами InBody и Accuniq и уменьшаются при измерении анализатором Медасс. При этом в анализаторах Accuniq и Медасс границы норм зависят от пола и возраста и имеют значения выше, чем у InBody.Заключение. По результатам анализа литературных данных и инструкций пользователя к анализаторам InBody, Accuniq и Медасс было показано, что различные значения и разнонаправленные тенденции изменения индексов ВнекВ/ОВО и ВнекВ/ВнукВ с увеличением возраста обследованных могут быть связаны как с различным положением тела во время измерения с помощью биоимпедансных анализаторов различных производителей, так и с различными нормативами значений индексов, разработанных на популяциях, имеющих свои особенности гидратационного статуса.</p></abstract><trans-abstract xml:lang="en"><p>Introduction. The absolute amount of total, extracellular and intracellular water of the body directly depends on the overall dimensions and component composition of the body, therefore, to assess the hydration status of the body, relative indicators of the water sectors of the body are used (as a percentage of body weight) and coefficients of water distribution in the body are used: ECW/TBW and ECW/ICW.Purpose. Determine what the difference is in assessing water distribution and body hydration status using bioimpedance analyzers of various modifications and manufacturers.Results and discussion. When the bioimpedance analyzers using to assess hydration status and the distribution of water in the body, it should be borne in mind that they have different standard values for the ECW/TBW and ECW/ICW indices. The obtained values should be interpreted only in accordance with the standards presented in the user instructions for the analyzer on which the assessment was carried out. The main differences between assessments by different analyzers are that normal index values increase with the age of the subject when measured by the InBody and Accuniq analyzers and decrease when measured by the Medass analyzer. At the same time, in the Accuniq and Medass analyzers, the normal limits depend on gender and age and have values higher than in InBody.Conclusion. Based on the results of the analysis of literature data and user instructions for the InBody, Accuniq and Medass analyzers, it was shown that different values and multidirectional trends in changes in the ECW/TBW and ECW/ICW indices with increasing age of the examined people can be associated both with different body positions during measurement using bioimpedance analyzers from different manufacturers, and with different standards for index values developed on populations with their own characteristics of hydration status.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>водные сектора организма</kwd><kwd>общая вода организма</kwd><kwd>внеклеточная вода</kwd><kwd>внутриклеточная вода</kwd><kwd>биоимпедансные анализаторы</kwd><kwd>статус гидратации организма</kwd><kwd>ВнекВ/ВнукВ</kwd><kwd>ВнекВ/ОВО</kwd><kwd>АВС‑01 Медасс</kwd><kwd>Accuniq ВС310</kwd><kwd>InBody</kwd></kwd-group><kwd-group xml:lang="en"><kwd>water sectors of the body</kwd><kwd>total body water</kwd><kwd>extracellular water</kwd><kwd>intracellular water</kwd><kwd>bioimpedance analyzers</kwd><kwd>body hydration status</kwd><kwd>ECW/TBW and ECW/ICW indices</kwd><kwd>ABC‑01 Medass</kwd><kwd>Accuniq BC 310</kwd><kwd>InBody</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках темы FGMF‑2022–0004 «Разработка инновационных подходов к оптимизации питания высококвалифицированных спортсменов с целью улучшения адаптационного потенциала и спортивной формы».</funding-statement><funding-statement xml:lang="en">The work was carried out within the framework of the scientific theme FGMF‑2022–0004 «Development of innovative approaches to optimizing the nutrition of highly qualified athletes in order to improve the adaptive potential and sports form».</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Watson PE, Watson ID, Batt RD.
