Abstract
BACKGROUND/ OBJECTIVES: The associations between empirically derived dietary habits and irritable bowel syndrome (IBS) have not been investigated. This study aimed to assess the relationship between empirically derived dietary habits and IBS in a large population of Iranian adults. SUBJECTS/ METHODS: In a cross-sectional study, dietary habits of 4763 adults were assessed in three domains, "meal pattern", "eating rate" and "intra-meal fluid intake". We used latent class analysis to identify classes of dietary habits. IBS was defined based on ROME III criteria. RESULTS: IBS was prevalent in 20.3% (n = 966) of the study population. Two distinct classes of meal patterns: "regular" and "irregular", three classes of eating rates: "moderate", "moderate-to-slow" and "moderate-to-fast" and two classes of fluid ingestion with meals: "moderate" and "heavy intra-meal drinking" were identified. After adjustment for confounders, "heavy intra-meal fluid intake" was protectively associated with IBS (OR = 0.79; 95% CI:0.64-0.96). When potential confounders were considered, "meal pattern" and "eating rate" were not significantly associated with IBS in the whole population. After adjustment for confounders, women with "irregular meal pattern" had a 30% greater risk of having IBS, compared with those with "regular meal pattern" (OR = 1.30; 95% CI:1.02-1.67). Overweight participants with "fast eating rate" were 70% more likely to have IBS, compared to those with "moderate eating rate" (OR = 1.70; 95% CI:1.13-2.55). "Irregular meal pattern" was related to frequency and severity of abdominal pain. CONCLUSIONS: We found a significant association between heavy intra-meal fluid intake" and IBS. More large-scale prospective studies are needed to affirm this association.
