Water consumption and prevalence of irritable bowel syndrome among adults

The association between dietary total antioxidant capacity and odds and severity of irritable bowel syndrome among Iranian adults: a cross-sectional study

BACKGROUND

Little evidence is available in terms of the role of dietary antioxidants in the management of irritable bowel syndrome (IBS) disease. This study aimed to examine the association between dietary total antioxidant capacity (dTAC) and odds of IBS and its severity.

METHODS

This cross-sectional study was conducted on 3,362 Iranian adults who were referred to health centers in Isfahan province, Iran. Participants' dietary intakes were collected using a semi-quantitative validated food frequency questionnaire (DS-FFQ). The dTAC was measured by the ferric-reducing antioxidant power (FRAP) method. Multivariable binary or ordinal logistic regression analyses were performed to estimate any associations between dTAC and odds of IBS, IBS severity, and IBS subtypes.

RESULTS

The average age and BMI of the participants and dTAC score were 36.3 ± 7.87 year, 24.9 ± 3.82 kg/m2. The prevalence of IBS, IBS with constipation (IBS-C), IBS with diarrhoea (IBS-D), mixed IBS (IBS-M), and un-subtyped IBS (IBS-U) were 22.2, 7.5, 4.6, 3.8, and 6.2%, respectively. In crude and adjusted models, the results did not show any significant association between dTAC and odds of IBS among whole and gender-age stratified populations. Being in the third compared with the first tertile of dTAC was not also significantly associated with odds of IBS severity. Besides, there were no significant associations between dTAC and odds of IBS-C, IBS-D, IBS-M, and IBS-U.

CONCLUSION

This study indicates that dTAC may not be associated with the odds of IBS and its severity even after stratification for gender and body mass index.

Association of Diet, Body Mass Index, and Lifestyle on the Gastrointestinal Health Risk in a Sample of Adults

Gastrointestinal functional disorders are characterized by abnormalities in motility with visceral hypersensitivity, representing a global public health problem. We aimed to determine whether eating habits, lifestyle characteristics, and body mass index (BMI) are associated with gastrointestinal health risk. The Gastrointestinal Health (GIH) test of the World Gastroenterology Organization (WGO) and the Roma IV criteria were applied. We obtained information on food consumption habits and aerobic exercise, among other variables. Not exercising regularly, drinking water and eating vegetables less than recommended, having high body weight, and taking symptomatic medication were variables that explained 73% of the probabilities of not having good GIH (R² = 0.734). According to Rome IV criteria, women had a 50% higher risk than men of having functional bowel disorder (RR 1.6, 95% CI: 1.04, 2.45). Among the men studied, eating few or no vegetables and drinking less than 1 L of water daily was more frequent; however, the women had significantly more intestinal symptoms. In addition, constipation was higher among women than men (p = 0.020). All of the above explains the prognostic value of eating habits and the importance of paying attention to body weight to reduce the risk of gastrointestinal disease.

Associations between Abnormal Eating Styles and Irritable Bowel Syndrome: A Cross-Sectional Study among Medical School Students

(1) Background: Few studies have investigated the association between eating styles and IBS. This study aimed to explore the association between abnormal eating styles and irritable bowel syndrome (IBS). (2) Methods: This cross-sectional study investigated students in China Medical University and Shenyang Medical College. Eating styles were evaluated by the Dutch Eating Behavior Questionnaire (DEBQ), and IBS was diagnosed according to Rome III criteria. Logistic regression was used to estimate odds ratios (ORs) and 95% confidence intervals (CIs). (3) Results: A total of 335 students were diagnosed with IBS. Students with the total scores in tertile 2 and 3 had 1.29 times and 2.75 times higher risk of IBS than students with the total scores in tertile 1, respectively. Simultaneously, the risk of IBS in the tertile 3 of external eating, emotional eating, and restraint eating trends was 3.87 times, 2.71 times, and 3.82 times higher than that of tertile 1, respectively. (4) Conclusions: this study showed that a high score in both total eating styles and each eating style was associated with the odds of having IBS and suggested that the psychological factors behind eating styles may play a critical role in controlling the IBS.

Prevalence of irritable bowel syndrome and its associated risk factors among university students of Bangladesh

Background

Irritable bowel syndrome (IBS) is a very common gastrointestinal disorder worldwide, but research regarding this disease is rare in Bangladesh. This study aimed to assess the prevalence of IBS and its associated risk factors among university students in Bangladesh.

Methods

This is a cross‐sectional study. A total of 300 randomly selected participants were included in this study. By using a structured questionnaire and anthropometric methods, we collected all the required data for our study. The diagnosis of IBS was based on Rome III criteria.

Results

The overall prevalence of IBS was 39.3%, but the majority (77.3%) had no basic awareness of IBS. In our study, anxiety and depression (χ² = 6.817; odds ratio [OR] = 1.910; 95% confidence interval [CI] = 1.172, 3.113; P = 0.011) had a significant relationship with IBS and IBS had a significant (P < 0.001) relationship with food intolerance (χ² = 8.737; OR = 2.130; 95% CI = 1.284, 3.531), chest pain (χ² = 7.482; OR = 2.035; 95% CI = 1.218, 3.401), and insomnia (χ² = 19.320; OR = 2.907; 95% CI = 1.794, 4.709). In our dietary data, the intake patterns of vegetables (P = 0.000), fast food (P = 0.000), and tea–coffee (P = 0.003) showed a strong significant association with IBS. On the other hand, monthly household income (P = 0.154) and body mass index (BMI) (P = 0.138) showed no significant association with IBS. Among our study subjects, IBS‐constipation (54.2%) was more common than IBS‐diarrhea (27.1%) and IBS‐mixed (18.6%). Moreover, among the 118 IBS respondents, 67.8% had a headache with increased flatulence (95.8%) as the most common IBS‐related complication.

Conclusion

IBS is common in university students of Bangladesh and is associated with anxiety, depression, and particular dietary patterns.
