Case-control differences in the accuracy of maternal recall may create spurious associations between suspected risk factors and perinatal conditions. We examined case-control differences in the accuracy of maternal recall and evaluated the impact of maternal reporting errors on observed measures of association. We compared interview information with information recorded on medical records for the mothers of 226 cases of Sudden Infant Death Syndrome (SIDS) and the mothers of 226 living controls. We found that having a child die from SIDS increased the sensitivity of recall for less than half of the 25 study variables. However, for 18 of the 25 variables, the mothers of SIDS cases were more likely than the mothers of living controls to report events that could not be confirmed on medical records. Case-control differences in recall accuracy did not appear to create spurious associations with SIDS or to bias most associations away from the null value.
母亲回忆准确性方面的病例对照差异可能会在疑似风险因素与围产期状况之间产生虚假关联。我们研究了母亲回忆准确性方面的病例对照差异，并评估了母亲报告错误对观察到的关联指标的影响。我们将访谈信息与226例婴儿猝死综合征（SIDS）病例的母亲以及226名存活对照的母亲的病历记录信息进行了比较。我们发现，孩子死于SIDS会使25个研究变量中不到一半变量的回忆敏感性增加。然而，在这25个变量中的18个变量上，SIDS病例的母亲比存活对照的母亲更有可能报告在病历上无法得到证实的事件。回忆准确性方面的病例对照差异似乎并未与SIDS产生虚假关联，也未使大多数关联偏离零值。
