1970 British Cohort Study: Sweeps 1-11 1970-2024: Secure Access

<p>The <span style="font-style: italic;">1970 British Cohort Study</span> (BCS70) is a longitudinal birth cohort study, following a nationally representative sample of over 17,000 people born in England, Scotland and Wales in a single week of 1970. Cohort members have been surveyed throughout their childhood and adult lives, mapping their individual trajectories and creating a unique resource for researchers. It is one of very few longitudinal studies following people of this generation anywhere in the world.<br><br>Since 1970, cohort members have been surveyed at ages 5, 10, 16, 26, 30, 34, 38, 42, 46, and 51. Featuring a range of objective measures and rich self-reported data, BCS70 covers an incredible amount of ground and can be used in research on many topics. Evidence from BCS70 has illuminated important issues for our society across five decades. Key findings include how reading for pleasure matters for children's cognitive development, why grammar schools have not reduced social inequalities, and how childhood experiences can impact on mental health in mid-life. Every day researchers from across the scientific community are using this important study to make new connections and discoveries.<br><br>BCS70 is run by the <a href="https://cls.ucl.ac.uk/cls-studies/1970-british-cohort-study/" target="_blank" style="background-color: rgb(255, 255, 255);">Centre for Longitudinal Studies</a> (CLS), a research centre in the UCL Institute of Education, which is part of University College London.

1970年英国出生队列研究（1970 British Cohort Study, BCS70）是一项纵向出生队列研究，追踪了1970年某一周内在英格兰、苏格兰与威尔士出生的17000余人的全国代表性样本。研究团队在队列成员的童年与成年阶段多次开展调查，绘制其人生轨迹，为研究者提供了独特的研究资源。该研究是全球范围内为数不多追踪该世代人群的纵向研究之一。

自1970年以来，研究团队已分别在队列成员5、10、16、26、30、34、38、42、46及51岁时完成调查。BCS70包含多类客观测量指标与丰富的自报数据，覆盖研究领域极广，可应用于众多主题的研究。五十余年来，BCS70的研究成果阐明了诸多影响社会发展的重要议题，核心发现包括休闲阅读对儿童认知发展的重要性、文法学校为何未能缩小社会不平等，以及童年经历如何影响中年心理健康。全球科研领域的研究者每日都依托这项重要研究开展新的关联分析与科学发现。

BCS70由伦敦大学学院（University College London, UCL）教育学院下属的纵向研究中心（Centre for Longitudinal Studies, CLS）运营管理。研究者可通过CLOSER Discovery网站查询BCS70的研究内容，包括调查问题、研究主题与变量信息。

如何获取多项纵向研究的基因及/或生物医学样本数据：
若需了解如何获取英国数据服务（UK Data Service, UKDS）未收录的BCS70生物医学数据，请访问纵向研究中心的基因数据与生物样本网页。

多基因指数（Polygenic Indices）
多基因指数需通过特殊许可SN 9439获取。研究团队已生成汇总得分，整合了多个不同基因对特定性状或特征的预估影响，例如个体罹患阿尔茨海默病、哮喘、物质滥用或精神障碍的风险。此类多基因得分可与现有调查数据结合，以更细致地解析队列成员的人生结局受何种因素塑造。

受限访问数据集（Secure Access datasets）
BCS70的受限访问版本相较于标准保护许可下的版本，拥有更为严格的访问条件。

SN 9115-1 《1970年英国出生队列研究：第1-11轮调查，1970-2024：受限访问版》目前包含第10、11轮调查的敏感调查数据，以及活动史数据。

申请获取BCS70受限访问数据集的研究者，需在其经济和社会研究理事会（Economic and Social Research Council, ESRC）认证研究者申请表中注明其同时希望获取的EUL数据集（可从BCS70系列研究访问网页选择）。

最新版本信息
2025年3月发布的第三版新增了第11轮（51岁）调查的敏感数据。
