Notes
Question asked: "Did this discomfort or pain occur only during your menstrual bleeding and not at other times?"
Question was asked to female participants (based on responses to question A2 in the Digestive Health questionnaire, not presented) when Field 21025 was neither "Never" nor "Prefer not to answer".
The question in this field was taken from the Diagnostic Criteria for Irritable Bowel Syndrome (IBS) developed by the Rome Foundation on Functional Gastrointestinal Disorders, used under licence.
