SAN DIEGO, CA -- May 23, 2000 -- A majority of men diagnosed with anxiety disorder meet the criteria for irritable bowel syndrome (IBS), according to a study presented at Digestive Disease Week. The study included only 28 patients being treated for anxiety disorder, so it should not be considered definitive, cautioned Jill Davies, PhD, a professor of nutrition at the University of London, where the investigation was conducted. About two-thirds of men with a Diagnostic and Statistical Manual (DSM)-IV anxiety disorder met the criteria for IBS. More than one-half of the women with anxiety disorder had symptoms compatible with diagnosis of IBS. Patients’ bowel habits and gastrointestinal symptoms were recorded weekly for 12 consecutive weeks. The study used the Rome I and Rome II criteria -- the universal definitions of IBS -- to detect the syndrome in this psychiatric population. The specificity apparently is higher in Rome II criteria; it requires two of three pain-related symptoms, among other modifications. Even when both "Rome criteria sets were applied to the same patients, the prevalence of IBS was higher in men. "That is the reverse of what’s seen when you look at the general population," where women with IBS outnumber men significantly, said Allan D. Shaw, the senior author of the study and a doctoral candidate at South Bank University, London, UK. The results suggest that men with anxiety disorder are at substantial risk for IBS, although it is not clear why more men being treated for anxiety disorder would experience symptoms consistent with a diagnosis of IBS, the researchers said.
