母亲回忆准确性的病例对照差异可能会在可疑危险因素和围产期状况之间产生虚假关联。我们检查了母亲回忆准确性的病例对照差异，并评估了母亲报告错误对观察到的关联测量的影响。我们将采访信息与 226 名婴儿猝死综合症 (SIDS) 病例的母亲和 226 名活着的对照组母亲的医疗记录中记录的信息进行了比较。 我们发现，在 25 个研究变量中，只有不到一半的变量因孩子死于 SIDS 而提高了回忆的敏感性。然而，对于 25 个变量中的 18 个变量，SIDS 病例的母亲比活着的对照组的母亲更有可能报告无法在病历中确认的事件。召回准确度方面的病例对照差异似乎不会与 SIDS 产生虚假关联，也不会导致大多数关联偏离零值。
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.
