[The selection of optimal methods for determining the perfect body weight for the assessment of the nutritional status].

In everyday practice, for a personalized approach to assessing nutritional status it is necessary to determine the ideal body weight of a person, but bio-impedance analysis of body composition widespread in stationary conditions in an outpatient setting is not always available. Therefore, it is necessary to use other methods for determining the ideal body weight, the results of which would be most comparable with bio-impedance analysis results. The aim of the work is a comparative analysis of various calculation methods for determining the ideal body weight and the results of bio-impedance testing. Material and methods. 830 men aged 18 to 44 years were examined. The ideal body weight was calculated by 16 common methods. The obtained results were compared with bio-impedance analysis of body composition. Results and discussion. To compare the accuracy of the coincidence of the results obtained by means of the used methods, the method of standard error of the model was used, as well as the correlation analysis was carried out, and regression models were constructed. A comparative analysis revealed the most informative methods for determining the ideal body weight, which are recommended for use in practice. Conclusion. As a result of comparing several methods for determining the ideal body weight, we can conclude that the methods closest to the determination of ideal body weight obtained by bio-impedancemetry are the methods of Borgardt, Monnerot-Dumayn and the Insurance Company "Metropolitan Life".
