Background: Foot length has been studied by various authors as proxy measurement which can be measured easily in sick and preterm newborns. This study was done to find the correlation of foot length with gestational age and birth weight. Methods: Study sample of 206 newborns was selected by simple random sampling technique. Born at CMCH, Bhopal from June 2021 to November 2022. Babies with limb deformities were excluded from the study group. Babies were grouped into term, preterm and gestational age was assessed by New Ballard score. Correlation of foot length with gestational age and birth weight was statistically analysed by correlation and regression analysis. Results: In the study, male newborns were 51% and female were 49%. Of the 206 newborns, preterms were 20.9%, terms were 79.1%. Mean birth weight was 2.657 kg with a standard deviation of 0.534. The mean foot length was 8.2 cm with a standard deviation of 0.7. Foot length correlated significantly (p < 0.05) with birth weight, gestational age in the neonates. Correlation was observed with birth weight (r = 0.794) which indicates strong positive association between them. Conclusions: Foot length is a easy and reliable anthropometric measurement to assess birth weight and gestational age in neonates, especially who are ill. Foot length can be reliably measured by peripheral heath care workers and could be used effectively for identifying and referring high risk newborns.
