초록

본 연구는 병원에 입원한 노인 환자에서 PG-SGA가 노
인 환자의 영양상태를 적절히 반영 하는지를 살펴보고자
하는 것으로서 구체적인 목적은 다음과 같다.
다른 영양 평가 도구인 Geriatric Nutritional Risk Index
(GNRI)와의 비교를 통하여 PG-SGA의 동시타당도를
평가한다.
다른 영양 지표들(BMI, TLC, albumin, total cholesterol,
hemoglobin)과의 연관성을 통하여 PG-SGA의
동시타당도를 평가한다.

영어초록

Purpose: This study was done to examine relevance of the Patient-Generated Subjective Global Assessment
(PG-SGA) to assess nutritional status of older hospitalized patients. Methods: This methodology study was
performed between April 1 and August 30, 2010, in a tertiary hospital geriatric ward in Seoul. Data on demographics,
disease-related factors, and nutritional factors were identified using a structured research form. The
nutritional status was examined using the Geriatric Nutritional Risk Index (GNRI) score, body mass index, total
lymphocyte counts, hemoglobin, albumin, and cholesterol at admission. Accuracy of the nutritional assessment
by PG-SGA and GNRI, using a contingency table and ROC curve was compared with other nutritional parameters
of undernourished and well-nourished patients as classified by the PG-SGA. Results: M±SD age of the patients
was 72±7.6 years, and 43 (59.7%) were female. Compared with the GNRI, the PG-SGA showed 90% sensitivity,
26% specificity, and 61% positive and 67% negative predictive values, and area under ROC curve (AUC) was
0.64. None of the nutritional parameters differed between the undernourished and well-nourished patients (all
p>.05). Conclusion: Use of the PG-SGA alone is not valid for nutritional assessment of acutely ill hospitalized
older patients, and should only be used together with other objective nutritional parameters.
