India is one of the diabetes capitals in the world and is expected to have more than 7 crore people with diabetes by 2030. Indians are susceptible to develop diabetes at a younger age and at a lower body mass index (BMI)  compared to Europeans . The Developmental Origins of Health and Disease (DOHaD)) hypothesis also known as Barker Hypothesis  proposes that early life nutrition and  growth influences health and  Non-communicable diseases (NCDs) risks across the life-course. Intrauterine period is the most crucial period in the life cycle and  NCD risks are programmed by disturbances in maternal and fetal nutrition. Infancy is the first time window (due to its proximity to intrauterine period) in a life cycle where fetal growth in a major way is  likely to influence subsequent risks in a major way.  Low birthweight, diagnosis of IUGR, prematurity have been used as a proxies for poor fetal growth to predict future risks. But the association of  actual fetal growth and  risks for NCD’s remains largely unknown. Our prospective infant cohort will enable to investigate the associations of  intrauterine life and infancy with the risk of NCD’s.
