Objective.为了比较以前怀孕的数据的质量，根据母亲的回忆，在以前的出生记录的实际数据，并量化在何种程度上回忆为基础的数据偏差的结果，在流行病学研究的不良生殖结局。通过农业普查和医疗出生登记之间的联系，我们确定了1967-1991年期间87 113名挪威女农民的174 764个单胎，包括533个晚期堕胎（16-27周）。数据被链接到同胞关系记录中。在常规出生记录中，母亲在每次分娩时提供有关以前胎儿丢失的信息。因此，我们既有基于回忆的信息，也有基于实际记录的信息。在所有母亲的损失记录在以前的记录，73.5%的回忆以前的损失（敏感性），而74.3%的所有母亲报告以前的损失也有一个损失在以前的同胞记录（阳性预测值）。根据同胞关系记录，既往流产后晚期流产的发生率高于根据母亲回忆的既往流产后晚期流产的发生率（18.3 vs 10.8/1000）。特别是缺乏对以前的短胎龄流产或当前分娩是晚期流产的回忆;这两种情况往往会削弱以前和当前不良结局之间的关联。谷物种植与有血缘关系记录的母亲的晚期流产有关（比值比，2.6），但与没有血缘关系的母亲无关（比值比，1.0）。当以前的损失信息是基于母亲回忆的优势比分别为1.4和1.3。对比性的兄弟姐妹关系记录比来自母亲回忆的数据提供了更有效的信息。
Objective. To compare the quality of data on previous pregnancies, based on maternal recall, to that of actual data in previous birth records, and to quantify to which extent recall based data bias results in epidemiologic studies on adverse reproductive outcomes.Methods. Through linkage between agricultural censuses and the Medical Birth Registry, we identified 87,113 Norwegian female farmers with 174,764 single births in 1967-1991, including 533 late abortions (16-27 weeks). Data were linked into sibship records. In routine birth records, mothers provide information at each birth on previous fetal loss. Thus, we had information both based on recall and on the actual record.Results. Among all mothers with a loss documented in previous records, 73.5% had a recall of previous loss (sensitivity), while 74.3% of all mothers reporting a previous loss also had a loss in previous sibship records (positive predictive value). Late abortion after a previous loss according to the sibship record was more frequent than after a previous loss based on maternal recall (18.3 vs. 10.8 per 1000). There was a particular lack of recall for previous losses of short gestational age or when the current birth was a late abortion; both conditions tended to deflate the association between a previous and a current adverse outcome. Grain farming was associated with late abortion in mothers with previous loss in sibship records (odds ratio, 2.6) but not among mothers without previous loss (odds ratio, 1.0). When information on previous loss was based on maternal recall the odds ratios were 1.4 and 1.3, respectively.Conclusions. Consecutive sibship records give more valid information than data derived from maternal recall.
