A study of correlation between foot length and gestational maturity and anthropometric measurements in neonates

Abstract

Background: This pinnacle’s the importance for alternative measurements which predicts birth weight and gestational age (GA). Foot length is a simple measure and does not require expertise. The aim of this study was to study correlation of foot length and GA among preterm, term and post-term neonates. Methods: This study was a prospective observational study done in 155 babies. Anthropometric measurements were taken within the first 24 hours of life. GA estimation was done using modified Ballard score. Foot length, head circumference and chest circumference were measured and noted. Weight of the baby was recorded using electronic weighing scale. Results: Foot length statistically correlated (p<0.05) with GA assessment using NBS, weight, length, head circumference and chest circumference. The highest correlation of foot length in term SGA and term AGA babies for foot length was with head circumference (r=0.74 and 0.64 respectively). In pre-terms, foot length correlated well with head circumference and birth weight (r=0.92, 0.84 and 0.92 respectively). There were no babies in preterm LGA group and post term SGA and LGA group. Conclusions: Foot length also statistically correlated with other parameters like birth weight, length, head circumference and chest circumference.
