Abstract

A case-control study was undertaken to investigate the effects of smoking, alcohol consumption, use of non-steroidal anti-inflammatory and other analgesic medications and family and medical history on the risk of ulcerative reflux oesophagitis (URO). We recruited 191 cases with URO diagnosed at endoscopy, 162 hospital controls who had also undergone endoscopy and 140 community controls from the Adelaide metropolitan area. From these three groups of subjects, 134 case-community control pairs, Matched on age, sex and postcode of residence and 142 case-hospital control pairs, matched on age, sex, hospital and endoscopist, were formed. Elevated non-significant risks were found in those smoking at least 20 cigarettes per day relative to those who never smoked (relative risk = 1.9, 95% confidence interval: 0.9-3.9 in case-hospital control pairs; relative risk = 1.9, 95% confidence interval: 0.9-3.7 in case-community control pairs). There was no elevation in risk associated with the use of non-steroidal anti-inflammatory drugs, with alcohol consumption, factors related to medical and reproductive history, nor with family history except for paternal history of heartburn (relative risk = 2.5, 95% confidence interval: 1.2-5.4 in case-hospital control pairs; relative risk = 1.9, 95% confidence interval: 1.0-4.0 in case-community control pairs). With the possible exception of smoking, no other risk factors for ulcerative reflux oesophagitis related to lifestyle are apparent.
