Bioimpedanciometry in nutritional and hydration assessments in a single dialysis center.

Background: Bioimpedance analysis (BIA) has been demonstrated to add accuracy to nutritional and volume status assessments in dialysis (HD) patients.

Aim: to describe a sample of dialysis patients from a single center on their demographics and BIA of volume distribution and nutritional status, and mortality during 12-month follow-up.

Methods: prospective observational cohort study to evaluate vintage HD patients with single-frequency BIA.
