Prevalence of dyspepsia and its associated factors among the adult population in southeast of iran in 2010

Global prevalence of functional dyspepsia according to Rome criteria, 1990-2020: a systematic review and meta-analysis

Although functional dyspepsia (FD) is a common functional gastroduodenal disorder with a high socioeconomic burden, little is known about its global prevalence. Thus, we performed a comprehensive study to estimate long-term trends in the prevalence of FD. We searched PubMed/MEDLINE, Embase, and Google Scholar from 1990 to 2022 for population-based studies that reported the prevalence of FD in adults (≥ 18 years old) according to Rome I, II, III, or IV criteria. The prevalence of FD was extracted from included studies to obtain pooled prevalence with 95% confidence intervals (CI) and 95% prediction intervals. Subgroup analysis was performed according to certain characteristics, including geographic region. A total of 44 studies met the eligibility criteria, including 256,915 participants from 40 countries across six continents. The overall global pooled prevalence of FD was 8.4% (95% CI 7.4-.9.5). The prevalence was the highest in Rome I (11.9%; 95% CI 5.1-25.4) and lowest in Rome IV (6.8%; 95% CI 5.8-7.9). Developing countries showed a higher prevalence than developed countries (9.1% versus 8.0%), and prevalence was higher in women, irrespective of the definition used (9.0% versus 7.0%). The pooled prevalence gradually decreased from 1990 to 2020 (12.4% [8.2-18.3] in 1990-2002 versus 7.3% [6.1-8.7] in 2013-2020). The prevalence of FD differs by country, economic status, geographical region, and sex, and the global prevalence has been gradually declining. Despite the heterogeneity of sample population, our study estimates the current global burden of FD and provides information to heath care policy decisions.

Combined Healthy Lifestyle Is Inversely Associated with Upper Gastrointestinal Disorders among Iranian Adults

OBJECTIVE

Although lifestyle-related factors have separately been examined in relation to functional gastrointestinal disorders (FGIDs), there is no epidemiological data on the combined association of lifestyle factors with these conditions. We aimed to examine how combinations of several lifestyle factors were associated with functional dyspepsia (FD), its symptoms, and gastroesophageal reflux disease (GERD) in a large group of Iranian adults.

DESIGN, SETTING, AND SUBJECTS

In a cross-sectional study on 3,363 Iranian adults, we calculated the "healthy lifestyle score" for each participant by summing up the binary score given for 5 lifestyle factors, including dietary habits, dietary intakes, psychological distress, smoking, and physical activity. A dish-based 106-item semi-quantitative validated food frequency questionnaire, General Practice Physical Activity Questionnaire, General Health Questionnaire, and other pre-tested questionnaires were used to assess the components of healthy lifestyle score. To assess FGIDs, a validated Persian version of ROME III questionnaire was used.

RESULTS

After adjustment for potential confounders, we found that individuals with the highest score of healthy lifestyle had 79 and 74% lower odds of FD (OR: 0.21; 95% CI: 0.05-0.92) and GERD (OR: 0.26; 95% CI: 0.09-0.69), respectively, compared with those with the lowest score. They were also less likely to have early satiation (OR: 0.28; 95% CI: 0.11-0.73), postprandial fullness (OR: 0.22; 95% CI: 0.09-0.50), and epigastric pain (OR: 0.44; 95% CI: 0.21-0.92). In addition to the combined healthy lifestyle score, low levels of psychological distress, a healthy diet, healthy dietary habits, and nonsmoking were separately and protectively associated with FGIDs.

CONCLUSION

We found that adherence to a healthy lifestyle was associated with lower odds of GERD, FD, and its symptoms in this group of Iranian adults, in a dose-response manner. Individual lifestyle-related factors were also associated with these conditions.

Effects of Endovascular Stent-Assisted Effects of Various Frequencies of Abdominal Naprapathy on Changes in Gastrointestinal Mucosal Cells in Spleen-Deficient Rabbits

Background

At certain frequencies, abdominal naprapathy effectively alleviates functional dyspepsia with spleen deficiency. The present study explored the effects of various frequencies of abdominal naprapathy on gastrointestinal mucosal cells in spleen-deficient rabbits.

Material/Methods

The model of spleen deficiency was established by the method of bitter cold and catharsis. The rabbits were treated with various frequencies (50–100 and 201–250 vibrations/min) of abdominal naprapathy.

Results

In model rabbits, gastrointestinal mucosal thickness was changed, mucosal epithelial cells were necrotic significantly, a large number of inflammatory cells were infiltrated, and duodenal villus were destroyed. The gastrointestinal mucosal cells had different degrees of regeneration and remodeling under various frequencies of abdominal naprapathy intervention. Among them, the abdominal naprapathy with manipulation frequency of 101–150 times/min showed the best effect.

Conclusions

The abdominal naprapathy, especially with frequency of 101~150 times/min, repairs gastrointestinal mucosal injury of spleen-deficiency rabbits.

Uninvestigated dyspepsia and associated factors of patients with gastrointestinal disorders in Dessie Referral Hospital, Northeast Ethiopia

Background

Dyspepsia is a common problem in the community and clinical practice with symptom(s) considered arising from the gastroduodenal region. Dyspepsia burden and associated factors vary from country to country. The aim of this study was to determine the prevalence of uninvestigated dyspepsia (UD) using Rome III criteria, associated risk factors and self-reported dyspepsia symptoms’ correlation with H. pylori infection.

Methods

A cross-sectional study was conducted among randomly selected 318 out patients with gastrointestinal complaints during the period from September 1 to December 30, 2015. All patients completed a questionnaire for collecting data regarding sociodemographic, lifestyle and functional gastrointestinal disorders. Diagnosis of dyspepsia was made according to the Rome III criteria. H. pylori infection was assessed using stool antigen test. SPSS version 20.0 statistical software package was used for data analysis.

Results

From a total of 318 patients, 48.4% had UD according to Rome III criteria; with 42.1% symptoms of epigastric pain/burning, 26.1% postprandial fullness and 22.6% early satiation. Epigastric pain/burning (AOR = 1.92, 95% CI 1.07–3.43), early satiation (AOR = 2.68, 95% CI 1.38–5.20) and belching (AOR = 4.7, 95% CI 1.54–14.40) were significantly correlated with H. pylori infection. H. pylori infection (AOR = 4.33, 95% CI 2.41–7.76) and aspirin/NSAIDs consumption (AOR = 5.29, 95% CI 2.82–9.93) were independent risk factors for UD. However, consumption of raw fruits/ vegetables at least once a week (AOR = 0.48, 95% CI 0.24–0.98) and taking two or more cups of tea a day (AOR = 0.339, 95% CI 0.17–0.70) were inversely associated with UD.

Conclusions

UD is highly prevalent among adults with gastrointestinal complaints. H. pylori infection is significantly associated with UD and correlates with its symptoms. Individuals with epigastric pain/burning, early satiation and belching should be primary focus of H. pylori infection diagnosis and treatment. The role of consumption of tea, raw fruits and vegetables on dyspepsia needs further large scale study.

Association of anxiety, depression, and psychological distress in people with and without functional dyspepsia

Background:

Current studies have indicated a high ratio of psychological problems in functional dyspepsia (FD) which causes disturbance in its management, so recognition these problems help the process of treatment.

Materials and Methods:

This was a cross-sectional study with a sample size of 4763 carried out in Isfahan University of Medical Sciences in 2011. Modified ROME III questionnaire was used to evaluate FD symptoms. Hospital anxiety and depression scale and 12-item General Health Questionnaire-12 was used to assess the psychological issue. Logistic regression analysis was used to assess the association of psychological problems and FD.

Results:

We showed that overly 654 (13.7%), 1338 (28.1%), and 1067 (22.4%) of participants, respectively had anxiety, depression, and of psychological distress. Seven hundred and ten (15.5%) participants were diagnosed with FD. Of all participants Mean scores of anxiety (P < 0.001), depression (P < 0.001), and psychological distress (P < 0.001) in participants with FD were significantly more than those with no FD. Multivariate logistic regression analysis showed that psychological problems, whether in the form of psychological distress odds ratio (OR): 2 (95% confidence interval [CI]: 1.3–3) and OR: 1.3 (95% CI: 1.1–1.7) in males and females, respectively, anxiety OR: 2.4 (95% CI: 1.5–3.9) and OR: 2.3 (95% CI: 1.7–3.2) in males and females, respectively) or depression OR: 2.2 (95% CI: 1.5–3.3) and OR: 1.7 (95% CI: 1.3–2.3) in males and females, respectively) were significantly linked to FD in both genders.

Conclusions:

The prevalence of FD is less in males than females, but psychological links were stronger in males. Thus, it is essential to consider and detect the psychological distress in these patients.
