Assess the nutritional status of patients with chronic obstructive pulmonary disease by SGA / 天津医药

ABSTRACT

Objective To explore the subjective global assessment (SGA) to evaluate the nutritional status of patients with chronic obstructive pulmonary disease(COPD). Methods Patients with stable COPD (n=122) were included and divid?ed into three groups base on their SGA scoresSGA-A (n=21), SGA-B (n=57), SGA-C (n=44). Nutritional status of all pa?tients was assessed by SGA. Anthropometric measurement, biochemical test, pulmonary function test, COPD assessment test (CAT) and shuttle walking test (SWT) were studied between all three groups to search statistical significance and correlation with SGA. Results Body mass index(BMI), arm muscle circumference (AMC) and forced expiratory volume in the first sec?ond%of predicted (FEV1%Pred) were all lower in SGA-B and SGA-C than those in SGA-A(P<0.05),there were no statis?tical differences of these parameters between SGA-B and SGA-C. Triceps skin fold (TSF) was lower in SGA-C than that in SGA-B than that in SGA-A, while CAT score is the reverse order (P<0.05). The walking distance of incremental shuttle walking test (ISWI) and the endurance time of endurance shuttle walking test (ESWI) were lower in SGA-C than that in SGA-A (P<0.05). There were no statistical differences of forced expiratory volume in the first second (FEV1)/forced vital ca?pacity(FVC), biochemical parameters between all three groups. SGA scores correlated positively with CAT and negatively with anthropometric parameters, FEV1%Pred and SWT (P<0.05). However no correlations was deduced between SGA scores with FEV1/FVC and biochemical parameters. Conclusion SGA scores correlated with anthropometric parameters, FEV1%Pred, CAT and SWT. SGA is an effective method to assess the nutritional status in patients with stable COPD.
