Methods: A total of 4763 individuals in 20 cities across Isfahan Province, Iran, were selected through cluster random sampling. The Rome III questionnaire in its complete form was used to investigate gastrointestinal symptoms. The other data collection tools consisted of the Stressful Life Events (SLE) Questionnaire, and Hospital Anxiety and Depression Scale (HADS). To analyze the data, t-test, chi-square test, and logistic regression analyses were used.
Results: The results of logistic regression analysis showed that the number of functional gastrointestinal disorders was the risk factor for stress level, anxiety, and depression and increased the odds ratio (OR) of these disturbances.
Conclusion: Increase in the number of functional gastrointestinal disorders was associated with more psychological comorbidity. Therefore, overlap of functional gastrointestinal disorders functional gastrointestinal disorders to be carefully considered and physicians should pay more attention to psychological factors when FGIDs overlap.
