Advanced Maternal Age Pregnancy, Overweight and Obesity, Scarred Uterus, Twin; Complicating Pregnancy
Conditions
Brief summary
The CMUBCS is a birth cohort study located in Shenyang, China. Its initial aim is to facilitate research on understanding the interplay between genes and environmental factors on disease etiology. Data are collected regarding environmental factors, family and lifestyle, clinical experimental outcomes and imaging results of pregnant women and children from birth to 18 years old. Biological samples including blood and tissue samples are also collected from the children and their parents.
Detailed description
Early life phase (fetal and infant) is a critical period for the development of health and disease in a person's life. Many adult chronic diseases, such as diabetes, cardiovascular and cerebrovascular diseases, all come from the exposure of negative environmental and behavioral factors during this period. By collecting the lifestyle data and clinical data of pregnant women at different periods, the appropriate indicators are anticipated to be selected to predict and evaluate the outcome of pregnancy and the health of the mothers and children in the long term. The status of overweight and obesity of children in Shenyang and its surrounding areas are anticipated to be analyzed by descriptive and etiological analysis through collecting the lifestyle data and clinical data of different periods of pregnant women and the lifestyle data of different developmental stages of children.
