BRIC-THSTI Faridabad and IIT Madras researchers have developed an India-specific model Garbhini-GA2 to determine the age of a foetus in a pregnant woman in the second and third trimesters precisely.
Key points
- Currently, the age of a foetus (gestational age, GA) is determined using a formula developed for Western populations and are likely to be erroneous when applied in the later part of pregnancy due to variations in the growth of the foetus in Indian population.
- The newly developed second and third-trimester GA formula, Garbhini-GA2, accurately estimates the age of a foetus for the Indian population, reducing error by almost three times.
- Accurate GA is necessary for the appropriate care of pregnant women and for determining precise delivery dates.
- It has been developed as part of the Interdisciplinary Group for Advanced Research on Birth Outcomes – DBT India Initiative (GARBH-Ini) program have developed a model for estimating the GA in pregnant women during the second and third trimesters.
- The Garbhini-GA2 is the first late-trimester GA estimation model to be developed and initially validated using Indian population data.
- Garbhini-GA2 which uses three routinely measured foetal ultrasound parameters, was developed using GARBH-Ini cohort data documented at Gurugram Civil Hospital, Haryana, and was initially validated in an independent cohort in South India. Garbh-Ini is a flagship programme of DBT.
