Objective:
To develop gender and gestational age-specific reference standards for segmental limb lengths in term neonates.
Methods:
A cross-sectional study was conducted in a tertiary hospital in Tamil Nadu from June, 2019 to October, 2020. Term neonates were included through convenient sampling. Segmental length of upper and lower limbs was measured using non-stretchable steel measuring tape and total body length was measured with infantometer. Gestational age-specific mean length of all limb segments and segmental index with reference to total body length were calculated.
Results:
950 term neonates were recruited. Their mean (SD) birth weight (kg) was 2.98 (0.34) and 17.5% were small for gestational age. Their mean (SD) total upper limb length (cm) and total lower limb length (cm) were 20.96 (1.22) and 19.6 (1.18), respectively. Gender-based difference was noted in total body and upper limb segment lengths. Segmental limb lengths had negligible positive correlation with gestational age but had a moderate positive correlation with total body length.
Conclusion:
Gender and gestational age-specific segmental limb lengths standards may help to identify abnormal limb lengths in neonates at birth.
