Abstract

Objectives: To describe the distribution of bioelectricalmeasurements among the Kaingáng from Rio Grande do Sul(RS). Cross-sectional study conducted among students of theIndigenous Lands of RS (N= 3248). Height (H) was measuredaccording to OMS. Resistance (R) and reactance (Xc) wereobtained through bioimpedance, and were adjusted by H. Thephase angle (AF) was estimated by: arc-tangent (Xc/R)*180/π.Mean values (SD) and centiles of the variables were calculatedby gender and age group. Means were compared using t Studentand ANOVA tests (p <0.05). The age proportions (%) among theevaluated individuals were: children (42.4), adolescents (56.0) andadults/elderly (1.6). In general, values of R and R/H were higheramong younger individuals and females. Mean values of Xc andXc/H changed among the different age groups, and, in general,lower values of AF were observed in those younger groups andfemales. Despite the limited possibilities of comparisons, ingeneral, the tendencies of distribution of the bioelectrical valuesamong the Kaingáng are in accordance with the results foundin other investigations. This study is a pioneer in the descriptionof bioelectrical measures for a Brazilian indigenous population,and it intends to serve as a base for comparisons with futurestudies in the area.
