To assess the validity of this approach, we analysed data from a national case\u2013control study of childhood cancer (diagnosed &amp;lt;15\u2009years) that collected health information from both interviews and medical records.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Methods<\/jats:title>\n                  <jats:p>Mothers\u2019 interview reports of infections and medications in pregnancy were compared with primary care records.

Most drugs and infections were underreported; in general practitioner records, antibiotic prescriptions were nearly three times higher and infections &amp;gt;40% higher. Decreasing with increasing time since pregnancy, sensitivity was \u2a7d40% for most infections and all drugs except \u2018anti-epileptics and barbiturates\u2019 (sensitivity 80% among controls). ORs associated with individual drug\/disease categories that were based on self-reported data varied from 26% lower to 26% higher than those based on medical records; reporting differences between mothers of cases and controls were not systematically in the same direction.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusions<\/jats:title>\n                  <jats:p>The findings highlight the scale of under-reporting and poor validity of questionnaire-based studies conducted several years after pregnancy.
