Main aim of cohort
This study aims to understand: 1. During the perinatal period, the roles of fetal, developmental and epigenetic factors in pathways to common non-communicable diseases (NCDs). To evaluate the role of fixed genetic risk variants, modifiable epigenetic markers, circulating metabolites and hormones in blood, and host-microbe interactions which can reflect past developmental influences, and in association with other factors, affect future trajectories of development and its relationship to NCDs. 2. During pregnancy and infancy period, the influence of prenatal and early postnatal factors on child health. To examine the role of maternal nutrition, lifestyle, emotional health, and other environmental factors in infancy that can influence the development of phenotypes in childhood which confer risk for later metabolic and mental disorders. 3. During pregnancy and postpartum period, the effect of factors in pregnancy and early postpartum period on maternal health. To examine the role of maternal nutrition, lifestyle, emotional health, and other environmental factors in pregnancy or postpartum period that can influence future maternal risk of metabolic disorders, including body weight changes. 4. During childhood, the influence genetic and epigenetics factors in combination with lifestyle on child health. To examine the role of genetic and epigenetic factors, lifestyle (physical activity and dietary intake), growth trajectories and other environmental factors that can influence the development of phenotypes in childhood which confer risk for later metabolic and mental disorders.
