方法和结果基本数据来源是芬兰儿童福利登记处。这些数据是通过与芬兰死因登记处的个别联系，使用每个儿童的个人身份证号码完成的。这项研究涵盖了1991年1月1日至1997年12月31日期间在芬兰接受照料的所有儿童（n= 13 371）。1%（133人）由于个人身份证号码错误而无法与死亡原因登记联系起来。所有受试者均出生于1973年1月1日至1997年12月31日之间，并随访至1999年12月31日或25岁生日（如果更早）或死亡（如果更早）。在研究期间，106人（32名女性和74名男性）死亡。按年龄标准化的死亡率比率用于比较队列中儿童的死亡率（分别为女孩和男孩）与芬兰同龄一般人口的死亡率。
Methods and resultsThe basic data source was the Finnish child welfare registry. The data were completed by individual linkage with the Finnish cause of death registry, using the personal identification number of each child. The study covered all children in Finland who were taken into care between 1 January 1991 and 31 December 1997 (n= 13 371). One per cent (133) could not be linked to the cause of death registry owing to errors in the personal identification number. All subjects were born between 1 January 1973 and 31 December 1997 and followed up until 31 December 1999 or, if earlier, their 25th birthday or, if earlier, their death. During the study period 106 individuals (32 females and 74 males) died. Mortality ratios standardised for age were used to compare the mortality of children in the cohort (girls and boys separately) with that of the general population of the same age in Finland.
