JiGenerations Health Cohort Study:Parental Exposure and Intergenerational Health in China

The growing recognition of maternal health's impact on offspring necessitates large-scale prospective cohort studies spanning the maternal-child life cycle. This study establishes a family-centered birth cohort of 100,000 Chinese participants, tracking from preconception through offspring adolescence to investigate early-life health trajectories and intergenerational transmission of diseases, health status, and psychological-behavioral patterns. Data collection includes biospecimens (placenta, cord blood, breast milk, blood, urine, feces) and multi-omics analysis (genomic, proteomic, metabolomic, microbiomic), alongside clinical information from preconception, pregnancy, birth through childhood (0-14 years). The cohort covers 24 stratified sites across China, incorporating real-time environmental monitoring (air pollution, meteorological data) and sociogeographic factors. Targeting reproductive-age couples (18-45 years) and their offspring, the study addresses multigenerational health linkages, urban-rural disparities, and regional diversity from 2025 to 2039. By integrating genetic, environmental and lifestyle data, this research will identify critical intervention windows and mechanisms for chronic disease transmission across generations, supporting China's "Healthy China" initiative and developing targeted strategies for population health and aging.

Peking University Birth Cohort in Weifang (PKUBC-WF)

The PKUBC-WF is a prospective cohort study carried out in Weifang city of Shandong, China. The primary aim of this study is to investigate the short-term and long-term effects of pre-pregnant and prenatal exposure on maternal and child health. Data are collected regarding environmental, nutritional and lifestyle exposures as well as short-term and long-term health outcomes of mothers and their children from birth to before 18 years old. Biological samples including peripheral blood, urine, placenta, umbilical cord, cord blood, and faeces are also collected.

The Ma'Anshan Birth Cohort (MABC)

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.
