Assessment of the reference values of intrauterine growth with particular to ponderal index for our region
Abstract
Introduction: Ponderal index (PI) is well known growth parameter from birth onwards but there are no reference values from 25 weeks till birth. Therefore, incorporation of a combination of weight and length may be a useful parameter to assess the growth.
Aims and Objectives: To set standards of ponderal indices for local population and to identify high risk vs low risk and growth difference between male and female babies.
Materials and Methods: This is prospective observational study done in NIMS, Jaipur from Jan. 2015 –June 2016 with503 institutional births fulfilling the inclusion criteria of singleton born intramural births with confirmed gestational ages between 25 to 43 weeks. These babies were then tabulated according to their gestational age and sex. The mean PI, standard deviation of PI were calculated and their curves were drawn.
Results: Out of 503 neonates studied, 272 (54.08%) were females and 231 (45.92%) were males.The minimum PI was seen at 28 weeks (1.98±0.10) with a gradual increase along with gestational ages. The maximum PI was at 42 weeks (2.65±0.28). No significant difference was seen in males and females.Growth velocity was maximum in earlier weeks. Sharp fluctuation in growth was seen around 30 to 33 weeks.
Conclusion: Classification of neonates with the help of such growth curves is inexpensive and does not require advanced knowledge. These values for PI cannot be used as standards rather used as reference values for our region for further research.
