Use of MUAC and BMI to assess the nutritional status of elderly Gond in Sagar district, Madhya Pradesh, India

Anthropometric techniques have always been the preferred method of assessing nutrition to determine malnutrition, overweight and obesity. The use of BMI and MUAC is widely accepted, although the MUAC requires validation. The present cross-sectional study was conducted among a total of 552 elderly respondents of Gond tribe selected from 30 villages of Kesli block of Sagar district (M.P.) including 273 males and 278 females. Weight, height and mean upper arm circumference were measured, and the relationships between mean upper arm circumference and BMI were analyzed. Receiver operating characteristic (ROC) analysis was performed and the area under the ROC curve was assessed. Sensitivity and specificity for different values of mid-upper arm circumference were calculated. The MUAC was found to have a significant and positive correlation with body weight (r=0.727), height (r=0.314) and BMI (r=0.626). The cut-off value was <23.0 cm. It can be concluded that there is a positive and significant correlation between BMI and MUAC in both men and women. The study also attempted to establish a suitable cut-off value for the detection of malnutrition using BMI and MUAC in the elderly Gond tribal population of central India.
