Québec Birth Cohort on Immunity and Health (QBCIH)
QBCIH was set up in 2010 in the province of Québec, Canada, to investigate the effect of immune stimulation in early life on the risk of developing selected autoimmune and inflammatory diseases, with an initial focus on the occurrence of asthma and diabetes through early adulthood. QBCIH used both retrospective follow-ups by extracting data from administrative sociodemographic and health databases and self-reported information from participants. QBCIH included over 81,000 persons born in 1974, followed until 1994. The cohort was expanded in 2017 to enable the study of rare diseases requiring a larger sample size and follow-up during adulthood. The expanded Quebec Birth Cohort on Immunity and Health (CO·MMUNITY) includes 400,611 individuals born in 1970–1974 in Québec, Canada, followed until 2014.
