Variabilidad en el cálculo del índice de masa corporal (IMC) aplicando diferentes medidas de estimación de la estatura en la evaluación del estado nutricional del adulto mayor.

Abstract

The older adult is complex; for this reason it is necessary to adequate the specific methods and indicators, using the measurements guaranteeing the opportune detection of the different nutritional problems so as to facilitate the diet - therapeutic interventions in both the nutrition field and public health . The objective was analyzing the agreement of the different estimate measurements of stature applied to the body mass index calculus (IMC) in the evaluation of the nutritional status of the older adults as well as developing a prediction formula of the height based on the present study data. The used method was not experimental, cross - sectioned type, with 75 older adults from the Hogar de Ancianos of Riobamba city whose measurements were taken as to weight, measured height, MB, ATR calculating IMC for each height; for the analysis the Program JMP 5.1 was used. The following results were generated: considering the relationshi p between the calculated height and the different segments, a higher significant correlation was evident between measured height and calculated height ATR which obtained an r 2 equal to 0.883. Using the multiple regression method three models were obtained an r 2 = 0.922 as compared to the other models. It is concluded that in the relationship between calculated height and the different segments such as MB, ATR, measured height there is a statistical significant difference and upon developing a prediction f ormula in this is age group there has been a contribution to science.
