Abstract:
Objective:To explore the association between phase angle (PA) of bioelectrical impedance analysis (BIA) and nutritional risk assessed by Nutritional Risk Screening (NRS-2002) Subjective Global Assessment (SGA),and hospital length of stay (LOS) in patients undergoing thoracic surgery.Methods:60 patients who underwent thoracic surgery were evaluated for nutrition risk and hospital length of stay (LOS) by NRS2002,SGA,albumin and bioelectrical impedance analysis.Results:The PA values were lower in the patients [men(3.85 ± 1.0)°,women(4.9 ± 0.6)°] than the control group [men(6.0 ± 1.0)°,women(5.4 ± 0.9)°,P ＜ 0.01].Patients were more likely to have lower PA values than the control group.NRS 2002:no risk (relative risk (RR) 2.8,95％ confidence interval (CI) =1.2 ～ 6.9),moderate risk (RR 3.9,95％ CI =1.8 ～ 8.6) and severe risk (RR 4.2,95％ CI =2.0 ～ 8.7);similar results were obtained by SGA:eutrophy (RR 2.5,95％ CI =0.9 ～ 6.9),Moderate malnutrition (RR 4.4,95％ CI =2.1 ～ 9.4),severe malnutrition (RR 3.9,95％CI =1.9 ～ 8.0);Patients with low PA values were more inclined to be hospitalized for more than 21 days compared with the control group (LOS ≥ 21 days,RR =4.4,95％ CI =2.2 ～ 2.8).Conclusion:There is a significant association between low PA values and nutritional risk and prolonged LOS.PA is helpful to identify patients who are at nutritional risk at hospital admission in order to provide an objective basis for determining the nutritional interventions of patients and judging the outcomes of the diseases.
