Application of WHO MUAC for age -Z score chart in diagnosis of SAM in Indian children: a comparative study with IAP classification
Abstract
Background: Mid upper arm circumference (MUAC) is a quick and easy method to determine malnutrition. Though considered age independent earlier, recently World Health Organization (WHO) has prepared MUAC Z score chart for age group between 3 months to 5 years.
Objective: To diagnose severe acute malnutrition (SAM) by using new WHO MUAC-Z score and to compare its efficacy with IAP classification for the diagnosis of SAM.
Methods: A cross sectional study was conducted in a tertiary care center of north east India. 500 children in the age group of 1 to 5 years, attending inpatient department, were included and a detailed history, clinical examination and anthropometry were taken. SAM was defined by IAP weight for age classification as grade 3 and 4 and by WHO MAUC-Z score <-3SD.
Results: Prevalence of SAM according to IAP grading was 11.8% and according to WHO MUAC was 17% with difference being significant (p<0.05). The mean values of weight and MUAC were less than WHO median values which suggest that there is significant malnutrition in the study population. Prevalence of SAM was more in <2 years of age.
Conclusion: MUAC is more sensitive than IAP grading in early diagnosis of SAM and facilitate early and effective treatment. New WHO MUAC-Z score alone can be used in screening malnutrition.
