Study design
Population cohort
Follow Up
We currently have protocols for data collection (on both parents (ALSPAC-G1) and their offspring (ALSPAC-G2)) for early pregnancy (up to 20 completed weeks of gestation), late pregnancy (≥28 weeks gestation), first 7–15 days, 6-months, 12 months, annually up to 7 years and then at 9 and 11 years. Our current plans are to extend this with protocols for data collection every 2 years up to the age of 21 over the next 5-years.
