Many studies have reported a high correlation between birth weight and other anthropometric measurements in newborns.23 A
WHO collaborative study identified arm and
chest circumferences as the most appropriate
indicators.4 The study also identified cut off
points, with the caveat that a single cut off
point may not be valid globally. Each region/
country will need to identify the cut off points
most suitable for them. This study aimed to
identify the most appropriate indicator and its
cut off point for identifying low birthweight
babies in northern India
