The association between meal and snack frequency and irritable bowel syndrome.

ABSTRACT:

Objective

The relationship between daily meal and snack frequency with irritable bowel syndrome (IBS) was less investigated in the literature. We aimed to evaluate this association with IBS symptoms.

Design

A cross-sectional study.

Setting

This investigation was performed in Isfahan, a large province in the centre of Iran. Individuals were asked to complete a self-administered questionnaire to quantify the numbers of daily main meals (one, two or three), snacks (never, 1-2, 3-5 or >5) and the total of them (<3, 3-5, 6-7 or ≥8). IBS and its subtypes were diagnosed according to Rome Ш criteria.

Participants

General adults (n 4669, 2063 men and 2606 women).

Results

The prevalence of IBS was 18·6 % in males and 24·1 % in females. Individuals consuming three main meals had 30 % decreased risk of IBS (OR 0·70, 95 % CI 0·52, 0·94) compared with those with one main meal in the crude model. After adjustments for all potential confounders this relation disappeared (OR 0·67, 95 % CI 0·43, 1·03). Gender-specified analysis revealed that women consuming three main meals per day had 32 % decreased likelihood of having IBS symptoms compared with one daily main meal takers (OR 0·68, 95 % CI 0·47, 0·99). This relation remained significant after adjustment for potential confounders (OR 0·56, 95 % CI 0·36, 0·89). A decreased likelihood of IBS in the highest category of main meal consumption compared with the lowest one was found in obese or overweight subjects (OR 0·54, 95 % CI 0·32, 0·91), after adjustment for all confounders.

Conclusions

Our findings suggested that there was no significant relation between main meal or snack frequency and IBS in Iranian adults, but a small inverse association was found among females and overweight/obese individuals in subgroup analysis. Further prospective studies are needed confirming these associations.

Project description:ObjectiveIrritable bowel syndrome (IBS) is a chronic pain disorder characterized by disturbed interactions between the gut and the brain with depression as a common comorbidity. In both IBS and depression, structural brain alterations of the insular cortices, key structures for pain processing and interoception, have been demonstrated but the specificity of these findings remains unclear. We compared the gray matter volume (GMV) of insular cortex (IC) subregions in IBS women and healthy controls (HC) and examined relations to gastrointestinal (GI) symptoms and glutamate + glutamine (Glx) concentrations. We further analyzed GMV of IC subregions in women with major depression (MDD) compared to HC and addressed possible differences between depression, IBS, IBS with depression and HC.DesignWomen with IBS (n = 75), MDD (n = 41) and their respective HC (n = 39 and n = 43) underwent structural brain MRI. IC subregion volumes were estimated using statistical parametric mapping software. General linear model approaches were applied to IC volumetric data and FDR-corrected partial correlation analyses assessed relations between GMV, GI symptoms and Glx concentrations.ResultsIBS patients had significantly smaller IC subregions than HC in both hemispheres but there was no significant difference between MDD compared with IBS and HC for any insular subregion. In IBS, the dorsal anterior insular volumes were negatively correlated with symptoms of nausea and pain, and the left ventral subregion showed a positive correlation with straining to defecate, while the posterior subregion volumes showed no relation to symptoms. In the anterior insula, concentration of Glx showed positive correlations with GMV bilaterally in HC and with GMV of the right anterior insula in IBS.ConclusionAs the interoceptive cortex, the insula shows substantial and disease-specific structural differences in patients with chronic interoceptive visceral pain. Particularly changes in the anterior proportions might be related to chronic exposure to or enhanced salience towards adverse interoceptive visceral signals and could be linked to biochemical changes, calling for further multimodal and longitudinal work.
