Objective: To determine the utility of MUAC to screen underweight hospitalized patients in a major Hanoi teaching hospital. Methods: Data from a one‐day study of patients 蠅19 years old admitted at Bach Mai Hospital, Hanoi, Vietnam (2010) were utilized. Data included actual weight and height, MUAC, age, sex, presence of edema, reason for admission, ward, and prior subjective weight loss (major, >10%) over six months. BMI was calculated and underweight defined as BMI < 18.5 (kg/m²; WHO standards). Receiver operating characteristic curve (ROC) analyses was performed. Results: A total of 420 inpatients were studied (51.4 ± 0.8 years old; 177 (42%) female. Patients were admitted for acute (n=174, 41%), chronic (n=186, 44%), elective (n=31, 7%), or other (n=29, 7%) reasons. Mean ± SD for BMI was 20.0 ± 0.2 kg/m² and for MUAC 24.5 ± 0.2 cm. Rates of underweight status, and moderate and severe, or severe thinness were 34%, 17%, and 8%. A total of 22% subjects exhibited edema and 15% reported major weight loss prior to admission. For underweight status, sensitivity of MUAC <23 cm was 71%, specificity 90%, (+) predictive value 79%, and (‐) predictive value 86%. Area Under Curve (AUC) for MUAC<23 cm was 0.81. Conclusion: MUAC <23 cm appears to be a good method to identify undernutrition in hospitalized adults in Vietnam (AUC 0.80‐0.90 is good). Further evaluation of MUAC in larger samples and association with hospital morbidity and mortality in Vietnam are needed. Grant Funding Source : Supported by the Abbott Fund
