基本原理：为了评估儿童保育对整个国家发病率的影响，建立了儿童保育数据库，将来自几个丹麦国家数据来源的个人可识别数据联系起来。本文介绍了儿童保育数据库的创建、特点和潜力。设计和测量：根据唯一的丹麦民事登记系统(DCRS)，将1989年至2004年期间0至5岁儿童的托儿出勤率、儿童和家庭特征、托儿设施特征和住院情况的登记数据联系起来。人口和样本规模：1989年至1998年期间，随着更多的市政当局开始登记托儿服务，数据库中的儿童数量有所增加，此后趋于稳定。2000年，数据库中的儿童人数最多为373,142人。从1999年到2004年，托儿数据库覆盖了丹麦所有0至5岁儿童的90%以上。在1岁时，53%的儿童在托儿机构注册，大约75%的儿童在3至5岁注册。潜力：儿童保育数据库为儿童保育和发病率领域的流行病学研究提供了独特的潜力。今后的更新和与其他数据来源的联系将进一步扩大该数据库的潜力。由于关联的全国登记数据的高质量，儿童保育数据库使进行具有高内部和外部有效性的流行病学研究成为可能。
Rationale: To assess the impact of childcare attendance on morbidity for an entire country the Childcare Database was created by linking person-identifiable data from several Danish national data sources. The present paper describes the creation, characteristics, and potential of the Childcare Database. Design and measurement: Based on the unique Danish Civil Registration System (DCRS) identification number register data were linked regarding childcare attendance, child and family characteristics, childcare facility characteristics, and hospitalizations for children aged 0 to 5 years in the period from 1989 to 2004. Population and sample size: The number of children in the database increased in the period from 1989 to 1998 as more municipalities started registering childcare, whereafter it stabilized. The maximum number of children in the database was 373,142 in 2000. From 1999 to 2004 the Childcare Database covered more than 90% of all 0- to 5-year-old children in Denmark. At age 1 year 53% of children were enrolled in a childcare facility and approximately 75% were enrolled from 3 to 5 years of age. Potential: The Childcare Database offers a unique potential for epidemiological research within the area of childcare and morbidity. Future updates and linkages with other data sources will further expand the potential of the database. Due to the high quality of the linked nationwide register data, the Childcare Database enables conduction of epidemiological studies of high internal and external validity.
