Avon Longitudinal Study of Parents and Children, 1990-2003: Social Science Sampler Datasets

The <i>Avon Longitudinal Study of Parents and Children</i> (ALSPAC, and also known as the 'Children of the 90s' study), which is based at the University of Bristol, is an ongoing longitudinal study of a population of children born to mothers resident in one geographic area in England. The overall objectives of the study are to understand the ways in which the physical and social environments interact over time with genetic inheritance to affect health, behaviour and development in infancy, childhood and then into adulthood. Information has been collected at regular and frequent intervals from pregnancy and throughout childhood concerning the child's physical environments, parental characteristics (including economic and educational indicators), social circumstances, and family relationships. ALSPAC recruited more than 14,000 pregnant women with estimated dates of delivery between April 1991 and December 1992, who were living in the Avon Health Authority area, to take part in the study. These women, the children arising from the index pregnancy and the women's partners have been followed up since then and detailed data collected throughout childhood.<br> <br> The datasets held at the UKDA are sampler datasets, and have been compiled using various questionnaire and assessment data from the ALSPAC study.

<i>Avon父母与儿童纵向研究</i>（ALSPAC，亦称"90年代儿童"研究）由布里斯托大学主持，是一项针对英格兰某地理区域内母亲所生儿童群体的持续纵向研究。本研究的总体目标是了解物理环境与社会环境如何随时间推移与遗传因素相互作用，从而影响婴儿期、儿童期乃至成年期的健康、行为与发展。自孕期及整个儿童期，研究定期且频繁地收集有关儿童物理环境、父母特征（包括经济与教育指标）、社会状况及家庭关系的信息。ALSPAC招募了14000余名预计分娩日期在1991年4月至1992年12月之间、居住于Avon卫生局辖区内的孕妇参与研究。此后，研究人员对这些女性、其首次妊娠所生子女及女性伴侣进行了随访，并在整个儿童期收集了详细数据。<br> <br>英国数据档案库（UKDA）所存数据集为样本数据集，由ALSPAC研究中的各类问卷及评估数据汇编而成。更多信息可查阅相关文档，若需了解更全面的研究内容，可访问<a href="http://www.bristol.ac.uk/alspac/" title="ALSPAC">ALSPAC</a>网站。<br> <br>
