In collaboration with our clinical partners, the Translational Health Science and Technology Institute (THSTI), we are analysing the GARBH-Ini cohort, a hospital-based observational pregnancy cohort to study multidimensional correlates of preterm birth in India. GARBH-Ini is one of the five “Atal Jai Anusandhan Biotech Missions – UNaTI” launched by the Government of India. We are building regression and machine learning models using anthropometric, clinical and obstetric characteristics of the mothers to estimate gestational age and predict preterm birth. These models, when validated and deployed will be instrumental reducing maternal and child mortality in India.
