PeriCBD is a brain-behaviour database designed to investigate individual differences in brain-mind development associated with perinatal factors. The long-term goal of this project is to create a national resource that covers the 34 provinces in China. In the initial pilot phase, the study recruited 68 children who had experienced adverse perinatal factors (perinatal factor group) and 173 children without any adverse perinatal factors (normal control group) from two sites in China: Anyang, situated in the northern region of Henan Province in central China, and Liangping, located in the northeastern part of Chongqing in China’s southwestern area. All children were aged 3 to 10 years at recruitment. Participants and their caregivers were recruited and assessed at baseline in 2021, and retrospective obstetric and paediatric data were collected from 2011 to 2018.

Recruitment is ongoing
