BACKGROUND: @entity28 has been identified as a potential risk factor for gastrointestinal (GI) symptoms, although the data from community samples remain sparse. We assess the associations between @entity344 and @entity28 in a population-based sample of Australian adults. METHOD: The prevalence of 26 @entity344 was determined by a validated postal questionnaire which was sent to 5000 randomly selected residents. The response rate was 60%. @entity344 were classified into six broader symptom groups based on the Rome II Criteria - @entity490 , esophageal symptoms, @entity4423 symptoms, @entity294 , @entity391 , and @entity1142 . @entity28 was defined according to body mass index using self-reported height and weight. RESULTS: The prevalence of @entity28 (BMI>= 30kg/m(2)) was 25.1%; 36.1% were overweight. There were significant and positive univariate associations between @entity28 and @entity490 (OR=1.75; 95% CI: 1.39-2.21), esophageal symptoms (OR=1.74; 95% CI: 1.36-2.22), @entity4423 symptoms (OR=1.43; 95% CI: 1.16-1.77) and @entity294 (OR=2.01; 95% CI: 1.65-2.45). The adjustment for socioeconomic characteristics and eating behaviors had minimal effect on the associations for @entity490 (OR=1.34; 95% CI: 1.01-1.79), esophageal symptoms (OR=1.35; 95% CI: 1.03-1.78), and @entity294 (OR=1.86; 95% CI: 1.49-2.31); however, the association between @entity28 and @entity4423 symptoms became non-significant. @entity28 was not related to @entity1142 . CONCLUSION: @entity28 is an independent risk factor for @entity490 , esophageal symptoms and @entity294 , but is not associated with @entity4423 symptoms or @entity1142 .
