The Ma'anshan Birth Cohort (MABC) is a population-based prospective pregnancy and birth cohort study that aims to explore the early environmental and genetic determinants of maternal and child health, with a focus on health outcomes including maternal health, children's cognitive and behavioral development, growth and physical development, video-screen behaviors, and asthma and allergic diseases.
MABC was officially launched in May 2013 at the Ma'anshan Maternal and Child Health Hospital in Anhui Province, and a total of 3,474 families were recruited as of September 2014 to continuously track the health status of mother-child pairs during pregnancy, delivery, and childhood, including basic family demographics, maternal pregnancy and birth history and past history, history of exposure to hazardous factors during pregnancy, children's diets and lifestyles, and children's physical and cognitive-behavioral development, MABC quantifies the attributional relationship between environmental chemicals, diet and nutrition, drug safety, psychological stress, lifestyle, biorhythm, endocrine metabolism and adverse birth outcomes, birth defects, neurodevelopmental disorders, developmental disabilities, etc., and identifies environmental, behavioral and genetic causative factors for birth defects and common developmental disorders, and identifies early warning signs and symptoms for early detection of birth defects. genetic causative factors, identify clinical biomarkers with early predictive effects, integrate and form a precise risk evaluation and early warning model, carry out regional comprehensive prevention and treatment applications, and promote the improvement of the quality of the birth population. Currently, MABC is conducting its 20th school-age follow-up visit.
