Efficiency of weight / height ratio in detection of protein energy malnutrition in Gujjar, Bakarwal and Pahari pre-school children.


 Field experience in developing countries has indicated that mild forms of protein-energy malnutrition may not be clinically discernible. This study investigated the efficiency of the weight-for-height2 ratio in predicting protein-energy malnutrition among 334 randomly selected preschool children from India's Guijar, Pahari, and Bakarwal populations. The weight-for-height2 measure (with a value of 0.0018 or more used as a cut-off for malnutrition) detected malnutrition in 69.76% of the preschool children [grade 1 (28.74%), grade II (22.75%), grade III (13.18%), and grade IV (5.09%) malnutrition]. Use of this ratio had a sensitivity of 86.27% and a specificity of 83.17% compared with the weight-for-age method, with predictive values of 92.20% and 74.41%. Although the weight-for-height ratio misclassified 16.83% of children with normal weight-for-age as malnourished, it is preferable to measures that rely on typically inaccurate age-related parameters.
