Gastrointestinal symptom-specific anxiety (GSA) has been reported to impact symptom severity in irritable bowel syndrome (IBS). This cross-sectional study of 1249 Japanese university students explored whether higher levels of GSA were associated with increased risk of having IBS.
GSA was measured using the Japanese version of the Visceral Sensitivity Index (VSI-J). The Rome III modular questionnaire was used to assess for IBS.
The prevalence rate of IBS symptoms was 21%. Logistic regression analysis was performed using the VSI-J cutoff point as the independent variable, and the presence or absence of a diagnosis of IBS as the dependent variable. Results indicate that for individuals above the VSI-J cutoff point, the odds ratio for having IBS was 3.40 (95% CI: 2.53-4.60).
Degree of GSA is associated with severity of IBS symptoms in Japanese university students.
