Abstract
Six anthropometric indicators based on weight, height, arm circumference (AC), and age were examined to predict mortality risk of children aged 12–59 mo in a rural area of Teknaf, Bangladesh. In the period 1981–85, 9861 measurements at 6-mo intervals were made on 2449 children. For all indices mortality risk was greater in the first 3 mo than in the second 3 mo in severely malnourished children. Mortality discriminating power of the indicators in terms of sensitivity and specificity was highest for AC and AC for age and lowest for weight-for-height. Logistic regression analysis showed that the predictive power of weight-, height-, and age-based indicators improved after adding AC whereas predictive power of AC did not improve after adding weight-based indicators. The relative risk of death in children with ACs measuring less than or equal to 120 mm was 12 times higher than in those whose ACs measured greater than 140 mm.
