To the Editor: I read with interest the research article on nutritional status published online in Indian Journal of Pediatrics [1]. Although an observational study, the authors deserve appreciation for bringing up data from North East India. However, I have certain queries:

  1. 1.

    What scale was used to measure socio-economic class?

  2. 2.

    WHO recommends use of country specific growth charts for children between 5 and 18 y [2]. So, what is the rationality of comparing new IAP growth charts with WHO standards?

  3. 3.

    “The over diagnosis of undernutrition and under diagnosis of overnutrition may be avoided by using the new IAP growth charts” – from what observation such conclusion was drawn?
