To overcome the logistic problems associated with weighing the newborn in the field, a study was undertaken to assess the usefulness of neonatal thigh circumference (TC) as an alternative to weight in identifying low birth weight infants. A strong correlation (p < 0.001) between thigh circumference (r=0.9180), mid-arm circumference (MAC, r=0.8292) and birth weight was found in 216 hospital births. A TC of 14.7 cm had a better sensitivity and specificity than a MAC of 8.4 cm in identifying infants weighing .ltoreq. 2500 g. Similarly, a TC of 13.9 cm has a better predictive value than a MAC of 8.0 cm in detecting infants .ltoreq. 2000 g. TC appears to be a reliable and cost effective indicator for the identification of low birth weight babies in the field.
