Dietary patterns and irritable bowel syndrome risk. (English)

Irritable bowel syndrome is a functional and non-histological disorder of the lower gastrointestinal tract that causes abdominal discomfort. Stress, dietary patterns, excessive use of laxatives, antibiotics and caffeine, other gastrointestinal disorders, sleep disorders and fluid intake are factors affecting this disease. The aim of the present study was to investigate the relationship between dietary patterns and irritable bowel syndrome in adults in Ahvaz. In this case-control study, the protocol of which was approved by the Vice-Chancellor of Research of Ahvaz Jundishapur University of Medical Sciences (Registration number RDC-9809) and the Ethics Committee of Ahvaz Jundishapur University of Medical Sciences (Registration number IR.AJUMS.REC.1398.908), a 147-item food frequency questionnaire (FFQ) was used to assess food intake. Extraction of the dominant dietary patterns was performed using principal component analysis (PCA) and finally the different tertiles of adherence to each dietary pattern with the risk of irritable bowel syndrome were examined using logistic regression and adjustment for confounders. Four dominant dietary patterns were extracted, which included traditional, unhealthy Western, and Mediterranean dietary patterns. After adjusting for confounders, the results showed that adherence to an unhealthy dietary pattern was associated with an increased risk of irritable bowel syndrome. Following a Mediterranean dietary pattern was associated with a reduced risk of IBS in the unadjusted model (OR=0.49, P=0.03). Although this association was not statistically significant in the adjusted models, there was a trend toward a reduced risk (P-trend=0.04). There was no significant association between adherence to traditional and Western dietary patterns with the risk of irritable bowel syndrome. There is an association between adherence to dominant dietary patterns and the risk of developing irritable bowel syndrome. The results of this study showed that adherence to an unhealthy dietary pattern was associated with an increased risk and adherence to a Mediterranean dietary pattern was associated with a reduced risk of developing the condition. Future studies could investigate the specific mechanisms through which diet influences IBS, taking into account the role of lifestyle and psychosocial factors [ABSTRACT FROM AUTHOR]
