The Jiaxing Birth Cohort is an unique resource to explore prenatal risk factors, early life feeding practice and growth pattern/adiposity in Chinese children. In addition, the Jiaxing Birth Cohort enables us to have a contemporary view of change in maternal and child characteristics and their impact on child growth in the past decade in this region.
