Análise vetorial de bioimpedância elétrica: uma comparação entre sobreviventes de câncer de mama e mulheres saudáveis

Abstract

Objective: To compare the body composition of breast cancer survivors and healthy women attended in reference centers for oncology in the city of Fortaleza through vector analysis of bioelectrical impedance. Methods: The sample is of convenience, using secondary data from a survey conducted between 2008 and 2010 related to 48 patients who underwent bioelectrical impedance analysis, resulting 18 survivors of the disease and 30 without a diagnosis of breast cancer. The variables analyzed included demographic, clinical, reproductive history, lifestyle, anthropometric and body composition. Data analysis was performed using the bioimpedance vector analysis through the data plot of resistance and reactance, which are expressed as R/height and Xc/height, using a specific software. Results: It was observed that the control group showed higher values of resistance and reactance, indicating greater amount of intact cells and body cell mass. Conclusion: The study showed differences in the body composition of women survivors of breast cancer compared to healthy women. These findings may guide possible clinical interventions.
