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

China100,000 participantsStarted 2025-08-01

Plain-language summary

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.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
