Objective: To measure the foot length of Newborns and to compare foot length to gestational age assessed by Ultrasound.Study design: It was a prospective Observational Foot length of Newborns fulfilling inclusion criteria was measured using electronic sliding caliper with an accuracy of one tenth of a millimetre. Head circumference was measured using flexible, non-stretchable measuring tape using cross tape method by Placing the measuring tape just above the eyebrows and ears, widest part of the head will be measured. Crown heel length will be measured using infantometer. All infection prevention, precaution standards were used during the time of measurement. Standard precautions were also applied for measuring equipment. All the measurements were taken within 24 hours of birth. After collection of data appropriate statistical test was applied. Results: The AUC score based on ROC curve was 0.90. The optimal cut-off foot length for full term categorization was 75.2 mm. The identification of preterm newborns with foot length < 75.2mm had a sensitivity of 92.0%, which means that 92% of preterm newborns (<37 weeks) can be detected by a foot length examination, specificity of 90.0% means that there is a 90% improbability of full term gestational age (more than 37 weeks) in newborns who have a foot length <75.2mm. Conclusion: In conclusion, newborn foot length can be used to predict gestational age. Longer newborn foot length is indicative of higher gestational age. The optimal cut-off point for diagnosing full term babies was 7.52 cm. Foot length <7.52 cm can be used to diagnose preterm babies. Newborn foot length is a reliable anthropometric measurement to diagnose preterm babies.
