Diagnostic Test Using Subjective Global Nutrition Assessment in Determining Nutritional Status in Patients with Cerebral Palsy in M Djamil Hospital Padang

Abstract

Background: Malnutrition often occurs in children with cerebral palsy, and anthropometric measurement becomes a challenge due to spastic posture. Subjective Global Nutrition Assessment (SGNA) is a helpful non-invasive screening tool to determine the nutritional status of its simplicity, ease to use, comprehensive, and affordable. Objective: This study aimed to determine the sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of SGNA in determining nutritional status in children with cerebral palsy Methods: A diagnostic test study was performed on 40 children with cerebral palsy who came to the outpatient clinic of M. Djamil Hospital from July to September 2022 where the caregiver signed the informed consent. Patients with a congenital anomalies and obesity were excluded. Measurements were carried out and nutritional status was determined by plotting weight and height data to WHO 2006/CDC 2000 anthropometric curve and caregivers were asked to fill in the questionnaire. Data analysis was performed with a 2x2 table using a computer program. Main outcome measures: sensitivity, specificity, positive predictive value, and negative predictive value of SGNA. Result: Data from 40 samples were collected to compare the sensitivity, specificity, positive predictive value, and negative predictive value of SGNA in determining nutritional status to anthropometric as a gold standard. The results were 91.3%, 88.2%, 91.3%, and 88.2 %, respectively. Conclusion: SGNA is recommended for screening nutritional status in children with cerebral palsy.
