The incidence of metabolic diseases in pregnant women is increasing rapidly, and the risk of metabolic diseases in children is also increasing. However, there is a lack of early predictive indicators for metabolic diseases in children, which cannot effectively prevent and treat metabolic diseases in children. This project will establish a clinical database and a long-term follow-up biological bio-bank through the follow-up of metabolic indicators before and during pregnancy, and form an early warning system for the effects of maternal endocrine and metabolic diseases on the metabolism of offspring. It will not only help to warn the impact of maternal endocrine system and metabolic diseases on the metabolism of offspring, but also build a transformation platform for the study of maternal endocrine and metabolic diseases and metabolic health of offspring, which has important clinical value for curbing the rapid growth of metabolic diseases such as diabetes and obesity in China. It is expected to provide an important theoretical basis for the window period of prevention and treatment of endocrine and metabolic diseases in China.
