雅芳父母与儿童纵向研究（ALSPAC）是一项基于人群的前瞻性研究。最初招募孕妇是在1990-1992年，从那时起就一直在跟踪这些孕妇及其家庭成员的健康和发育情况。使用关联的招募和卫生服务记录回顾性地构建了符合条件的抽样框架。通过7岁和18岁的主要招募活动，欢迎其他有资格参加研究的后代；从7岁起就通过机会接触。本数据说明提供了指数儿童7岁以后入学的最新情况，重点是18岁以后入学的情况，这一点以前没有描述过。共有913名额外的G1（指数儿童队列）参与者自7岁起加入该研究，其中195名自18岁起加入。这一额外的入组提供了14901名1岁时存活的G1参与者的基线样本。
The Avon Longitudinal Study of Parents and Children (ALSPAC) is a prospective population-based study. Initial recruitment of pregnant women took place in 1990-1992 and the health and development of the index children from these pregnancies and their family members have been followed ever since. The eligible sampling frame was constructed retrospectively using linked recruitment and health service records. Additional offspring that were eligible to enrol in the study have been welcomed through major recruitment drives at the ages of 7 and 18 years; and through opportunistic contacts since the age of 7. This data note provides a status update on the recruitment of the index children since the age of 7 years with a focus on enrolment since the age of 18, which has not been previously described. A total of 913 additional G1 (the cohort of index children) participants have been enrolled in the study since the age of 7 years with 195 of these joining since the age of 18. This additional enrolment provides a baseline sample of 14,901 G1 participants who were alive at 1 year of age.
