The Correlation of Foot Length and Gestational Age
Abstract
Introduction: Accurate assessment of gestation maturity is not possible in all newborn infants especially when they are sick and need intensive care support. Gestational age is important for prediction of morbidity, mortality and further management. Objective: To study the correlation between foot length and gestational age among preterm, term and post-term neonates. Methods: 60 new-borns, born over a period of 6 months were included in the study. Gestational age was assessed by antenatal USG scan and babies were grouped into term, preterm and post-term. Correlation of foot length with gestational age was statistically analysed. Foot length measurements were done using a Vernier caliper within 48 hours after birth. Results: Out of 60 neonates, being 20 of each preterm, term and post term average foot length were 5.6cm, 7.4cm and 8.35cm, respectively. The foot length is directly proportional to gestational age.
