Abstract Establishing a three-generation family cohort enables the investigation of the effects of genetic, epigenetic, lifestyle, and parenting factors in the grandparental (F0) and parental (F1) generations on the growth, development, and disease onset and progression of the offspring (F2). It facilitates further exploration of the biological mechanisms underlying the impact of intergenerational factors on the health of the offspring (F2), providing evidence for the formulation of public health policies and measures related to child health management and infant and young child care. Currently, the development of multi-generational cohorts in China remains in a preliminary stage, with no systematic multi-generational research framework yet established. Drawing on prior evidence-based scientific research, existing cohort studies, and the practical experience of multidisciplinary experts in maternal and child health, this consensus defines the scope of three-generation family cohorts regarding their definition, significance, key technologies, and application scenarios. It provides technical recommendations for establishing relevant cohorts, aiming to support research areas such as the intergenerational transmission of childhood diseases, the maternal intrauterine environment, and the tracing of family rearing environments. This will facilitate the early prevention and control of diseases manifesting in childhood and adulthood, ultimately promoting the comprehensive and healthy development of children.
