Jiangsu Birth Cohort (JBC)
The JBC has followed over 7,600 assisted reproductive technology (ART) families and over 14,900 spontaneously conceiving families since April 2014 in three cities in Jiangsu province, China: Nanjing, Suzhou, and Changzhou. Families were recruited from single major hospitals in each of these cities. ART families were identified following consultation for ART treatment at ART clinics, while spontaneously conceiving families were identified from obstetrics departments when they established health record profiles between 8 and 14 weeks of gestation. The JBC is a subset of the China National Birth Cohort, a nationwide birth cohort study across 12 Chinese provinces and 30 medical centres.
