Abstract Introduction: Malnutrition is an important risk factor for postoperative complications and the phase angle (PA) marker, since it is interpreted as an indicator of membrane integrity and as a predictor of body cell mass. It has been described as a useful parameter to identify malnutrition. Objective: To verify the association between PA and indicators of risk screening and assessment of nutritional status in pre-surgical patients. Methods: Observational study performed in the period from May to December 2014 in a university hospital in the Northeast of Brazil, including 83 patients in the preoperative period. We studied demographic, clinical, anthropometric variables (body mass index (BMI), arm circumference (AC)), Nutritional Risk Screening (NRS, 2002), and PA through bioelectrical impedance. Results: The mean age was 51.3 ± 14.9 years, predominantly female (73.5%). There was a predominance of oncological surgeries (53%). A prevalence of 27.7% of low PA, 30.1% of nutritional risk and 27.7% of malnutrition was observed, according to AC. A positive correlation with the other parameters (BMI and AC) was observed in relation to age (r = -0.421; p
