Prevalence, severity, and risk factors of symptomatic gastroesophageal reflux disease among employees of a large hospital in northern India

Efficacy and safety of pantoprazole and itopride in patients with overlap of gastroesophageal reflux disease and dyspepsia: A prospective, open-label, single-arm pilot study

BACKGROUND AND AIM

Combining proton pump inhibitors (PPIs) with prokinetics can provide synergistic action in patients with gastroesophageal reflux disease (GERD) and overlapping dyspepsia, but data regarding this is lacking.

METHODS

This single-center, prospective study evaluated the efficacy and safety of 6-week treatment with fixed-drug combination (FDC) of pantoprazole (PPI) and itopride (prokinetic) in 50 patients with ≥3 month history of GERD and overlapping dyspepsia refractory to pantoprazole. Efficacy was assessed as reduction in GERD symptom assessment scale (GSAS) distress score for 15 symptoms from baseline to week 6. Adverse events (AEs) were monitored up to week 6.

RESULTS

Although heartburn was the most common symptom at week 6 (26.8%), its frequency significantly decreased from baseline (84.0%; P <0.01). A similar trend was observed for other symptoms: pressure/discomfort inside chest (19.5%), belching (14.6%), regurgitation (12.2%), bloating (9.8%), flatulence (9.8%), early satiety (7.3%), acidic/sour taste in mouth (7.3%), nausea (7.3%), frequent gurgling in stomach/belly (4.9%), and pressure/lump in throat (2.4%). Mean distress scores of all symptoms markedly decreased at week 6. Three AEs (n = 2) of moderate intensity were reported.

CONCLUSION

The FDC of pantoprazole and itopride showed favorable efficacy and safety in patients with GERD and overlapping dyspepsia refractory to pantoprazole monotherapy. Nevertheless, further studies are warranted.

Management advice for patients with reflux-like symptoms: an evidence-based consensus

Patients with reflux-like symptoms (heartburn and regurgitation) are often not well advised on implementing individualised strategies to help control their symptoms using dietary changes, lifestyle modifications, behavioural changes or fast-acting rescue therapies. One reason for this may be the lack of emphasis in management guidelines owing to 'low-quality' evidence and a paucity of interventional studies. Thus, a panel of 11 gastroenterologists and primary care doctors used the Delphi method to develop consolidated advice for patients based on expert consensus. A steering committee selected topics for literature searches using the PubMed database, and a modified Delphi process including two online meetings and two rounds of voting was conducted to generate consensus statements based on prespecified criteria (67% voting 'strongly agree' or 'agree with minor reservation'). After expert discussion and two rounds of voting, 21 consensus statements were generated, and assigned strength of evidence and Grades of Recommendation, Assessment, Development, and Evaluation (GRADE) rating. Eleven statements achieved the strongest (100%) agreement: five are related to diet and include identification and avoidance of dietary triggers, limiting alcohol, coffee and carbonated beverages, and advising patients troubled by postprandial symptoms not to overeat; the remaining six statements concern advice around smoking cessation, weight loss, raising the head-of-the-bed, avoiding recumbency after meals, stress reduction and alginate use. The aim of developing the consensus statements is that they may serve as a foundation for tools and advice that can routinely help patients with reflux-like symptoms better understand the causes of their symptoms and manage their individual risk factors and triggers.

Dietary and Lifestyle Factors Related to Gastroesophageal Reflux Disease: A Systematic Review

We performed this review to clarify which dietary and lifestyle factors are related to gastroesophageal reflux disease. Through a systematic search of the PubMed, EMBASE, China National Knowledge Infrastructure (CNKI), and Chinese BioMedical Literature (CBM) databases, we identified articles with clear definitions of GERD, including nonerosive gastroesophageal reflux disease (NERD), reflux esophagitis (RE) and Barrett’s esophagus (BE), that included dietary and lifestyle factors as independent factors affecting the onset of GERD (expressed as odds ratios (ORs) or relative risks (RRs) and 95% confidence intervals (CIs)). Due to heterogeneity among the studies, we used descriptive statistical analyses to analyze and synthesize each outcome based on the disease type. In total, 72 articles were included, conducted in ten Western countries (26 articles in total) and nine Eastern countries (46 articles in total). We categorized dietary factors into 20 items and lifestyle factors into 11 items. GERD is related to many irregular dietary and lifestyle habits (such as a habit of midnight snacking: OR=5.08, 95% CI 4.03–6.4; skipping breakfast: OR=2.7, 95% CI 2.17–3.35; eating quickly: OR=4.06, 95% CI 3.11–5.29; eating very hot foods: OR=1.81, 95% CI 1.37–2.4; and eating beyond fullness: OR=2.85, 95% CI 2.18–3.73). Vegetarian diets (consumption of nonvegetarian food (no/yes); OR=0.34, 95% CI 0.211–0.545) and no intake of meat (OR=0.841, 95% CI 0.715–0.990) were negatively related to GERD, while meat (daily meat, fish, and egg intake: OR=1.088, 95% CI 1.042-1.135) and fat (high–fat diet: OR=7.568, 95% CI 4.557–8.908) consumption were positively related to GERD. An interval of less than three hours between dinner and bedtime (OR=7.45, 95% CI 3.38–16.4) was positively related to GERD, and proper physical exercise (physical exercise >30 minutes (>3 times/week): OR=0.7, 95% CI 0.6–0.9) was negatively correlated with GERD. Smoking (OR=1.19, 95% CI 1.12–1.264), alcohol consumption (OR=1.278, 95% CI 1.207–1.353) and mental state (poor mental state: OR=1.278, 95% CI 1.207–1.353) were positively correlated with GERD. RE (vitamin C: OR=0.46, 95% CI=0.24–0.90) and BE (vitamin C: OR=0.44,95% CI 0.2-0.98; vitamin E: OR=0.46, 95% CI 0.26–0.83) were generally negatively correlated with antioxidant intake. In conclusion, many dietary and lifestyle factors affect the onset of GERD, and these factors differ among regions and disease types. These findings need to be further confirmed in subsequent studies.

Prevalence and risk factors for gastroesophageal reflux disease in the Indian population: A meta-analysis and meta-regression study

BACKGROUND

Indian population-based studies on the prevalence and risk factors for gastroesophageal reflux disease (GERD) are scanty, and a meta-analysis and a meta-regression of prevalence and risk factors based on the existing data have not yet been reported.

METHODS

A systematic review of all the available publications from India reporting data regarding prevalence and risk factors of GERD was performed. Heterogeneity was assessed using I² statistics. The meta-analysis was undertaken to measure the average proportion reported in the existing studies, and meta-regression models were used to explore the risk factors for it.

RESULTS

The nine studies included 20,614 subjects; the prevalence of GERD ranged from 5% to 28.5%. The summary effect size (weighted average proportion) estimated by meta-analytic model was 0.1415 (95% confidence interval [CI] 0.099 to 0.197). The results for the test of heterogeneity that included tau² (0.37, 95% CI 0.21 to 1.80), I² (98.9%, 95% CI 98.01 to 99.77), and the Q-statistic (707.670; p < 0.0001) suggested high heterogeneity in the effect sizes. The pooled proportion of GERD (random-effects model) was 15.573 (95% CI 11.046 to 20.714). In the meta-regression model, sample size (p = 0.005) explained about 50% of the heterogeneity.

CONCLUSION

The pooled prevalence of GERD in the Indian population is 15.6 (95% CI 11.046 to 20.714). The risk factors were age, body mass index (BMI), non-vegetarian diet, tea/coffee intake, tobacco, and alcohol consumption. However, there was significant heterogeneity in the studies.

Prevalence and risk factors of gastroesophageal reflux disease in a rural Indian population

BACKGROUND

Studies on frequency and risk factors of gastroesophageal reflux disease (GERD) in the rural Indian population are scanty.

METHODS

This household survey was undertaken by the trained interviewers in the adult population (≥ 18 years) in four villages in northern India using translated-validated Enhanced Asian Rome III and hospital anxiety and depression questionnaires.

RESULTS

Of 2774 subjects, 2019 (72.8%) had no heartburn. Heartburn frequency was as follows: 314 (11.3%) once/week, 143 (5.2%) twice/week, 85 (3.1%) thrice/week, 69 (2.5%) four times/week, 48 (1.7%) five times/week, 18 (0.6%) six times/week, 41 (1.5%) daily, 37 (1.4%) > once daily. A total of 298 (10.7%) had GERD (definition: heartburn > twice/week). Older age (36.5 vs. 35 years), non-Hindu religion (7, 2.4% vs. 30, 1.2%), lower education (127, 42.6% vs. 789, 31.9%), lower socioeconomic class (94, 31.5% vs. 517, 20.9%) and income (below Indian National Rupees [INR] 458; 105, 35.2% vs. 599, 24.2%), non-vegetarian diet (15, 5% vs. 105, 4.2%), intake of tea/coffee (260, 87.2% vs. 1687, 68.1%), carbonated soft drinks (216, 72.5% vs. 1234, 49.8%), and alcohol (48, 16.1% vs. 313, 12.6%), tobacco chewing (116, 38.9% vs. 681, 27.5%), and smoking (105, 35.2% vs. 672, 27.1%) were associated with GERD on univariate analysis. On multivariate analysis, body mass index > 25 kg/m² (odds ratio [OR] 1.23; 95% CI 0.88-1.71), predominant rice eating (1.13; 0.74-1.74), tobacco chewing and smoking (1.68; 1.24-2.30 and 1.36; 0.99-1.88), and alcohol (1.2; 0.78-1.83) and carbonated soft drinks (2.48; 1.79-3.44) intake were associated with GERD. A total of 122 (41%) had associated functional dyspepsia. Psychological comorbidities were commoner among those with than without GERD.

CONCLUSION

In this rural Indian population, 10.7% had GERD and predominant rice eating, tobacco chewing, and carbonated soft drink intake were the risk factors. Psychological comorbidities were common.

Indian consensus on gastroesophageal reflux disease in adults: A position statement of the Indian Society of Gastroenterology

The Indian Society of Gastroenterology developed this evidence-based practice guideline for management of gastroesophageal reflux disease (GERD) in adults. A modified Delphi process was used to develop this consensus containing 58 statements, which were generated by electronic voting iteration as well as face-to-face meeting and review of the supporting literature primarily from India. These statements include 10 on epidemiology, 8 on clinical presentation, 10 on investigations, 23 on treatment (including medical, endoscopic, and surgical modalities), and 7 on complications of GERD. When the proportion of those who voted either to accept completely or with minor reservation was 80% or higher, the statement was regarded as accepted. The prevalence of GERD in India ranges from 7.6% to 30%, being  < 10% in most population studies, and higher in cohort studies. The dietary factors associated with GERD include use of spices and non-vegetarian food. Helicobacter pylori is thought to have a negative relation with GERD; H. pylori negative patients have higher grade of symptoms of GERD and esophagitis. Less than 10% of GERD patients in India have erosive esophagitis. In patients with occasional or mild symptoms, antacids and histamine H₂ receptor blockers (H2RAs) may be used, and proton pump inhibitors (PPI) should be used in patients with frequent or severe symptoms. Prokinetics have limited proven role in management of GERD.

Gastro-oesophageal reflux disease symptoms and associated risk factors among medical students, Saudi Arabia

Background and aims

Gastro-oesophageal reflux disease (GERD) is a common gastrointestinal disease worldwide that is associated with impaired quality of life and higher risk of complications. The identification of risk factors is necessary for preventive measures. The aim of this study is to evaluate the prevalence of GERD symptoms as well as its relation to body mass index (BMI) and other risk factors among medical students of Jeddah and Rabigh branches, King Abdul-Aziz University, Saudi Arabia.

Subjects and methods

A cross-sectional study was conducted at the Faculty of Medicine in Rabigh, King Abdul-Aziz University, Saudi Arabia. The study included 197 medical students from Rabigh and Jeddah branches of the university. The study employed a Gastroesophageal Reflux Disease Questionnaire which is derived from a self-administered validated GERD questionnaire (GerdQ).

Results

The prevalence of GERD symptoms was 25.9%. The most frequent symptoms were regurgitation and burning sensation. High BMI, family history, energy drinks and fried food were found to be statistically significant risk factors (p<0.05) by univariate analysis. However, the logistic regression for the prediction of GERD symptoms among medical students showed that only family history had a significant correlation (p<0.05).

Conclusion

GERD symptoms were common in medical students of King Abdulaziz University, Saudi Arabia. Family history was found to be a significant predictor of GERD symptoms. Effective educational strategies for groups with significant risk factors of GERD need to be implemented.

Alcohol Consumption and the Risk of Gastroesophageal Reflux Disease: A Systematic Review and Meta-analysis

Aims

Epidemiologic evidence on alcohol consumption increasing the risk of gastroesophageal reflux disease (GERD) is contradictory. This study aimed to investigate the correlation between alcohol consumption and GERD by a meta-analysis of observational studies.

Short summary

Gastroesophageal reflux disease (GERD) is a prevalent disease, and the incidence is rising. We conducted a meta-analysis of observational studies, indicating that there was a significant association between alcohol consumption and the risk of GERD. This finding provides important implications for the prevention and control of GERD.

Methods

Two investigators retrieved relevant studies on PubMed, Cochrane and EMBASE, respectively. The summary odds ratios (ORs) and 95% confidence intervals (CIs) were calculated by random effects model to assess the association. Heterogeneity was quantified using the Q statistic and I2. Subgroup analysis, publication bias and sensitivity analysis were also conducted.

Results

Twenty-six cross-sectional studies and three case-control studies were included in the meta-analysis. The pooled random effects OR was 1.48 (95%CI, 1.31-1.67; I2 = 88.8%), in comparison between drinkers and non-/occasional drinkers. For reflux esophagitis and non-erosive reflux disease, two subtypes of GERD, the ORs were 1.78 (95%CI, 1.56-2.03; I2 = 87.5%) and 1.15 (95%CI, 1.04-1.28; I2 = 0.3%), respectively. In addition, the pooled OR for drinkers who drank <3-5 times or days per week was 1.29 (95%CI, 1.14-1.46; I2 = 35.5%), while for those who drank more frequently, the OR was 2.12 (95%CI, 1.63-2.75; I2 = 55.1%). Dose-response analysis showed a linear association between alcohol consumption and GERD (Pfornonlinearity=0.235). The pooled OR for a 12.5 g/day increment of alcohol was 1.16 (95%CI, 1.07-1.27; P = 0.001).

Conclusions

This meta-analysis provides evidence for a potential association between alcohol drinking and the risk of GERD. The increase in alcohol consumption and frequency showed a stronger association with GERD.

A population-based study on prevalence and risk factors of gastroesophageal reflux disease in the Tibet Autonomous Region, China

Objective

To investigate the prevalence and risk factors of gastroesophageal reflux disease (GERD) in the Tibet Autonomous Region, China.

Methods

In this cross-sectional study, a stratified random sampling method was used for collecting samples in the Tibet Autonomous Region. A total of 10,000 individuals were selected from October 2016 to June 2017. A previously-published, validated questionnaire including six items related to the symptoms of GERD was used for evaluating GERD. In addition, basic demographic data, lifestyle, dietary habits, medical history and family history of GERD were investigated to identify risk factors of GERD.

Results

A total of 5,680 completed questionnaires were collected and analyzed. The prevalence of GERD in this area was 10.8%. Age (30-40 years vs. under 18 years, odds ratio (OR): 3.025; 40-50 years vs. under 18 years, OR: 4.484), education level (high school vs. primary, OR: 0.698; university vs. primary, OR: 2.804), ethnic group (Han vs. Tibetan, OR: 0.230; others vs. Tibetan, OR: 0.304), altitude of residence (4.0-4.5 km vs. 2.5-3.0 km, OR: 2.469), length of residence (<5 years vs. ≥5 years, OR: 2.218), Tibetan sweet tea (yes vs. no, OR: 2.158), Tibetan barley wine (yes vs. no, OR: 1.271), Tibetan dried meat (yes vs. no, OR: 1.278) and staying up late (yes vs. no, OR: 1.223) were significantly (all P < 0.05) and independently associated with GERD.

Conclusions

The prevalence of GERD is high in the Tibet Autonomous Region, China. Geographic conditions, ethnic group and lifestyle are risk factors for GERD.

Prevalence and factors associated with gastroesophageal reflux disease in southern India: A community-based study

BACKGROUND AND AIM

Gastroesophageal reflux disease (GERD) is common worldwide with significant expenditure for health care. Community-based data on the prevalence of GERD in India remains scarce. This study was conducted to determine the prevalence of GERD and to identify potential associations.

METHODS

A community-based survey of adults (aged ≥18 years) was done through population proportionate to size sampling in urban and rural areas of Vellore district, Tamil Nadu, India. GERD was defined as heartburn and regurgitation occurring at least twice per week. Associations between GERD and gender, age, anthropometric measures, and consumption of tobacco, alcohol, meat, and milk were evaluated. Odds ratios (OR) with 95% confidence intervals were derived from logistic regression models.

RESULTS

Of 6174 participants (3157 urban, 2599 male), 8.2% had GERD. The prevalence was higher in urban (11.1%) compared to rural areas (5.1%) (p < 0.001). Among patients with GERD, 34.3% used medications daily for symptom relief. On univariate analysis, GERD was associated with female gender, living in an urban area, age >30, BMI >25, and infrequent milk consumption. On multivariate analysis, female gender (OR 1.3; 95% CI 1.1-1.6), living in urban area (OR 2.3; 95% CI 1.9-2.8), age >30 years (OR 1.9; 95% CI 1.4-2.5), BMI ≥ 25 kg/m² (OR 1.3; 95% CI 1.1-1.6), and infrequent milk intake (OR 1.6; 95% CI 1.3-1.9) were independently associated with GERD.

CONCLUSION

Symptomatic GERD was found in 8.2% of respondents in this representative southern Indian community, being more prevalent in urban residents, women, older, and obese individuals.

Prevalence and risk factors of gastroesophageal reflux disease among Shaqra University students, Saudi Arabia

Introduction

Gastroesophageal reflux disease (GERD) is one of the most common chronic gastrointestinal disorders in adults, it develops when the stomach contents reflux and rise up into the esophagus as a result from lower esophageal sphincter dysfunction. Stomach acid that touches the lining of the esophagus causes symptoms and complications. The classical symptoms of GERD include heartburn, usually after eating, chest pain, and regurgitation.

Aim

To measure the prevalence of gastroesophageal reflux disease and determine its risk factors among the students of Shaqra University.

Methods

A cross-sectional study was conducted using a structured questionnaire distributed among Shaqra University students after multistage stratification and random sampling technique to stratify students according to gender and the three main colleges in Shaqra city, Saudi Arabia. The sample size was determined to be 435 with the precision of ± 5% and a 95% confidence interval (CI). The questionnaire included demographic data like age, gender, height and weight, lifestyle, and dietary habits. Statistical data were analyzed using the Statistical Package for Social Sciences (SPSS) version 16. Results with a P value of <0.05 were considered statistically significant.

Results

A total of 400 [227 (56%) male and 173 (43%) female] participants were evaluated. And 95 participants got a gastroesophageal reflux disease questionnaire score of ≥8 thus determining the prevalence of GERD to be 23.8%. Univariate analysis revealed that gender, smoking, familial history of GERD, high body mass index (>25 kg/m²), fast food, tea, carbonated beverages consumption, quick eating, and sleeping within 1 hour of dinner are associated with symptomatic GERD (P < 0.05).

Conclusion

The results show a high prevalence of GERD in Shaqra university students and the presence of many modifiable risk factors which merits the conduction of public health campaigns to raise awareness about the disease and its risk factors.

Epidemiology of Childhood Onset Essential Hypertension

The knowledge of epidemiology of a disease is paramount in identifying preventive measures. Currently there is a paucity of literature on the epidemiologic determinants of childhood onset essential hypertension (EH). We evaluated children with EH, ascertained in a rigorous manner, in a large multiethnic population in a tertiary pediatric hypertension clinic. We enrolled children with and without EH and obtained data by in-person interview of their parents and by direct anthropometric measurements including blood pressures. A total of 148 children (76 hypertension probands, 72 control probands, and males 53%, mean age 12.2 ± 4.3 years) were enrolled. Of these 148 children, 51 pairs were matched 1:1 on ethnicity, gender and age (± 2.5 years). In this study we evaluated the demographics, genetic predisposition and a variety of exposures including, socioeconomic, perinatal, lifestyle and environmental, between cases and controls. All measures were similar between cases and controls other than a significantly higher BMI (p = 0.01) and rates of obesity (p = 0.03), and a difference of near-significance in any family history of EH (p = 0.05) higher in cases compared to controls. The odds of obesity was 3.5 times higher among cases than controls. In this study we evaluated a variety of prenatal and postnatal exposures that could potentially contributed to the EH phenotype in childhood. The findings of the study elucidate the epidemiology of EH in children and two important associated risk factors, any family history of hypertension and a higher body weight.

Basal lower esophageal sphincter pressure in gastroesophageal reflux disease: An ignored metric in high-resolution esophageal manometry

Manometry and 24-h pH interpretation have seldom been studied. Our aim was to study these parameters as gold standard in reflux disease and to identify predictors of pathological acid reflux. Retrospective case record review of all patients with reflux disease evaluated using endoscopy, manometry, and 24-h pH testing from 2010 to 2016. Patients were categorized using Johnson-DeMeester score into two groups-group I (score > 14.7, normal study) and group II (< 14.7, normal study). These groups were compared for the above-mentioned parameters. Appropriate statistical tests were applied. P-value < 0.05 was considered significant. The study group includes 94 patients (median age 44 years, 63.8% males). Sixty (63.8%) and 34 patients belonged to groups I and II, respectively, 76.6% patients had normal endoscopy while the remaining had mild esophagitis. Peristalsis was normal in 66%, followed by ineffective esophageal motility (19.1%) and fragmented peristalsis (14.9%). Demography, symptoms, endoscopy findings, and peristalsis characteristics were similar between the two groups. Group II patients had significantly lower basal lower esophageal sphincter (LES) pressure (11.9 vs. 16.6; p < 0.02), lower integrated relaxation pressure (5.7 vs. 7.4; p < 0.01), and larger separation between LES and crural diaphragm (1.7 vs. 1.4 cm; p < 0.003). Basal LES pressure < 10 mmHg had the highest likelihood ratio (2.2) to predict an abnormal pH study. Basal LES pressure, integrated relaxation pressure, and hiatus size correlated with pathological acid reflux. Hypotensive basal lower esophageal sphincter pressure was the best predictor of an abnormal pH study but with negative linear correlation.

Diagnostic Efficacy of 24-hr Esophageal pH Monitoring in Patients with Refractory Gastroesophageal Reflux Disease

BACKGROUND:

Gastric reflux is one of the most important causes of the referral of patients to the internal clinic, which in some cases causes problems for patients due to resistance to common treatments. Therefore, timely diagnosis and treatment of this group of patients are very important.

AIM:

The purpose of the present study was to determine the off-proton pump inhibitor (off-PPI) 24 h pH-impedance analyses in patients with refractory gastroesophageal reflux disease (GERD) attending to Taleghani Hospital since 2009 to 2017.

METHODS:

In this observational descriptive-comparative off-PPI study, 572 patients with refractory GERD who were referred to Taleghani Hospital in Tehran from 2009 to 2017 were selected, and the results of 24 h pH Impedance analysis were then assessed.

RESULTS:

The results of 24h pH-impedance indicated that 7% of cases belonged to Pure Acid Reflux followed by weakly Acid (1%), non-acid (0.3%), mixed & gas (5.2%), functional (58.4%) and oesophagal hypersensitivity (28%). Furthermore, weakly acid plus acid was also found to be 8% and Weakly Acid + Acid + Non-Acid were determined as 8.3%.

CONCLUSIONS:

Our findings suggested that nearly more than half of the patients with refractory GERD would have a functional disorder in the 24h pH-impedance analysis.

Prevalence and risk factors of gastro-esophageal reflux disease among undergraduate medical students from a southern Indian medical school: a cross-sectional study

Objective

Gastro-esophageal reflux disease (GERD) affects all age groups, and various lifestyle as well as psychological factors are recognized as risk factors for GERD. Undergraduate medical students are exposed to lifestyle changes and psychological stressors. We aimed to study the prevalence of GERD among undergraduate students of a medical school in southern India in a cross-sectional survey using a validated symptom score.

Results

A total of 358 undergraduate medical students participated in the study. There were 188 (52.5%) males and 170 (47.4%) females; the mean (SD) age of the participants was 20.3 (1.5) years. A total of 115 (31.2%) participants had at least one episode of heartburn per week, while 108 (30.1%) participants had at least one episode of regurgitation per week. Heartburn or regurgitation of at least mild severity was present in 115 (32.1%) and 108 (30.16%) of participants respectively. Based on the symptom score, a diagnosis of GERD was made in 18 (5.02%) students. Frequent consumption of carbonated drinks (OR = 3.63 [95% CI 1.39–9.5]; P = 0.008) and frequent consumption of tea or coffee (OR = 4.65 [95% CI 1.2–17.96]; P = 0.026) were significantly associated with a diagnosis of GERD.

Prevalence of Gastroesophageal Reflux Disease in Saudi Arabia

Background

Gastroesophageal reflux disease (GERD) is a common chronic gastrointestinal tract disease. The incidence is higher in Asian and Arab countries. In Saudi Arabia, there are few studies that have assessed the prevalence of GERD among some cities' communities. Hence, this study aims to study the prevalence of GERD among the general population of Saudi Arabia.

Methods

A cross-sectional study was designed to determine the prevalence of GERD among the community of Saudi Arabia. The sample was randomly gathered through self-administered validated GERD questionnaire (GerdQ) to diagnose GERD, during the period from November to December 2016. The sociodemographic data was assessed for all participants. The data were analysed using Statistical Package for Social Sciences version 21.0 (SPSS); the t-test was used to assess the association of GERD and sociodemographic data.

Results

The sample was comprised of 2,043 participants. Female and male were 51.8% and 48.2%, respectively. Mean age was 29.6 years with the standard deviation of 10.5 years. The GERD prevalence was 28.7%. It was found statistically significant among divorced/widow (34.9%, P = 0.003). In contrast, there was no association between GERD's prevalence and gender, age, residence status, education level, occupation, and blood group (P > 0.05).

Conclusions

The prevalence of GERD among Saudi population is higher than that in Western countries and East Asia. It affects divorced/widow, obese and those with a sedentary lifestyle. It is advocated that national programs and educational campaigns for prevention of this disease and its complications should be established.

Dietary habits and obesity indices in patients with gastro-esophageal reflux disease: a comparative cross-sectional study

Background

Gastro-esophageal reflux disease (GERD) is suggested to be associated with some socio-demographic and lifestyle factors. Although the roles of some factors such as obesity are well documented, evidence on the impact of other factors such as dietary habits are still inconclusive. The aim of this study was to determine the relationship between socio-demographic and lifestyle factors with GERD in participants referred to a teaching hospital in Zahedan, South-East of Iran.

Methods

This comparative cross-sectional study was conducted during 2014–2015. All patients completed a structured questionnaire regarding information on socio-demographic status, lifestyle factors and dietary habits. Anthropometric indices including body mass index (BMI) and waist circumference (WC) were used to determine general and central obesity, respectively. Data were analyzed using SPSS software version 22. Value of p < 0.05 was considered as statistically significant.

Results

Five hundred and five participants, including 285 GERD and 220 Non-GERD participants participated in the study. In univariate analysis, being married (OR = 1.57, 95%CI = 1.04, 2.36), general obesity (OR = 1.77, 95%CI = 1.11, 2.81), central obesity (OR = 2.09, 95%CI = 1.46,3.01) and consumption of citrus fruits between meals (OR = 1.69, 95%CI = 1.04, 2.73) were associated with higher odds of GERD, while higher educational level (OR = 0.53, 95%CI = 0.36,0.77) and regular physical activity ≥2 h/week (OR = 0.53, 95%CI = 0.30, 0.94) were associated with lower odds of GERD. In the adjusted model, central obesity (OR = 1.88, 95%CI = 1.18, 3.01) and consumption of citrus fruits between meals (OR = 2.22, 95%CI = 1.30, 3.81) were positively associated with odds of GERD, while higher educational level (OR = 0.55, 95%CI = 0.33, 0.91) was associated with decreased odds of GERD.

Conclusion

According to the results of the current study, central obesity as determined by WC and citrus fruit intake were independent factors associated with GERD. Therefore, lifestyle modification might have a positive effect in the treatment of GERD in an urban population of Iran.

Gastroesophageal reflux disease among population of Arar City, Northern Saudi Arabia

Background

During the recent decade, several studies about prevalence of symptom-based GERD have revealed increase of its prevalence. In addition to the highly disturbing typical symptoms, it has a series of known consequences and may affect the quality of life.

Objective

To determine the prevalence of gastroesophageal reflux disease (GERD) as well as their main characteristics and risk factors among the population of Arar City, Northern Saudi Arabia.

Methods

A cross-sectional study was carried out on a sample of 302 individuals from population of Arar city from October 01, 2016 to May 30, 2017, using a researcher made questionnaire and checklist. The questionnaire was administrated in online method. Data were analyzed by SPSS version 22, using descriptive statistics and Chi-Square test.

Results

total prevalence of GERD among the studied respondents was 61.8%. In 11.8% there was severe pain. Further, 61.8% reported loss of appetite as an associated condition, 57% reported nausea and vomiting, 55.9% indigestion, 55.4% food regurgitation, 41.4% chest pain and 35.5% headache. The main found risk factors were fatty meals in 84.9% followed by coffee drinking in 77.4%, stress in 71%, spicy food in 58.1% NSAD in 24.7% and smoking in 17.2%. There were no significant effect of sex, age, educational level, marital status or occupational status in the occurrence of GERD (p>0.05).

Conclusion

This is the first population-based study in Arar, Northern Saudi Arabia, reporting prevalence of GERD. The rate of 61.8% was substantially high. Coffee drinking, stress, spicy food, prolonged use of NSAID, fatty meals and smoking were the reported risk factors. Population-based endoscopic studies are recommended.

Prevalence and the risk factors of gastro-esophageal reflux disease in medical students

Background

Gastroesophageal reflux disease (GERD) is a commonly prevalent gastrointestinal disorder in adults. Very few studies on magnitude of GERD in student community have been done and there is none so far from India. Rigorous MBBS curriculum makes medical students prone for reflux symptoms. Hence, this study was conducted to determine the prevalence of GERD in medical students and the potential risk factors associated with it.

Methods

This was a cross sectional observational study conducted on medical students in a premier medical college of India. All participants were interviewed for GERD symptoms using the validated questionnaire on frequency scale for the symptoms of GERD. Additional 11 questions include enquiries on medical history and lifestyle factors.

Results

Of the 600 students, 150 (25%) had GERD symptoms. Of these, 88 (58.6%) had mild, 58 (38.6%) moderate, and 4 (2.7%) severe reflux symptoms. Fifty eight (38.6%) of students with GERD had associated dyspepsia. On univariate analysis higher BMI, final years of MBBS course, use of NSAID or alcohol, inadequate sleep, sleeping within one hour of taking dinner, missing breakfast regularly and quick eating were significantly associated with GERD (p < 0.05).

Conclusions

Prevalence of symptoms of GERD in medical students is 25%, majority had mild symptoms. Associated dyspeptic symptoms were present in 38.6%. Factors predisposing to GERD in them are higher BMI, final years of MBBS course, use of NSAID, inadequate sleep, sleeping within one hour of taking dinner, missing breakfast on regular basis and quick eating.

Prevalence and Correlates of Gastroesophageal Reflux Disease in Southern Iran: Pars Cohort Study

BACKGROUND

Prevalence of gastroesophageal reflux disease (GERD) is increasing worldwide. We aimed to estimate the prevalence of GERD in Pars Cohort Study (PCS) and to find its correlates.

METHODS

We used the baseline data from PCS. PCS was conducted in the district of Valashahr in Fars province in southern Iran from 2012 to 2014. 9264 inhabitants who were 40-75 years old, and agreed to participate were enrolled. Data were collected by a structured questionnaire and simple physical examination of all participants.

RESULTS

Generally, 58.50% (95% CI 57.49 - 59.51) of the participants had GERD and 25.10% (95% CI 24.22 - 25.99) experienced it at least weekly. Approximately, 32.0%, 52.0%, and 24.4% of the participants reported heart burn sensation, regurgitation, and both symptoms, respectively. Being female (OR: 1.45, 95% CI 1.27 - 1.65), being older (OR: 1.20, 95% CI 1.06 - 1.36), being divorced/ widowed/separated (OR: 1.38, 95% CI 1.01 - 1.91), and lower education (OR: 1.43, 95% CI 1.02 - 2.03) were associated with frequent GERD.

CONCLUSION

GERD is common in PCS and its prevalence is close to that in western countries. Being female, higher age, being divorced/widowed/separated, lower education, history of hypertension, anxiety, insomnia, and non-cigarette tobacco smoking were associated with frequent GERD. We are going to investigate the causal relationship between these risk factors and GERD in the next stages of PCS.

Gastroesophageal Reflux Disease and its Association with Body Mass Index: Clinical and Endoscopic Study

INTRODUCTION

Obesity is rapidly becoming a pandemic and poses a serious health risk to the individuals. Abdominal obesity is quite common in India and is a prime risk factor for diseases like diabetes, coronary artery disease, Gastroesophageal Reflux Disease (GERD), osteoarthritis etc. A complex and multifactorial aetiopathogenesis of GERD exists in presence of obesity. The current study focuses on high Body Mass Index (BMI), a marker of obesity, as a risk factor for GERD and aims for a better understanding of their complex association.

AIM

To study the association between the BMI and symptoms as well as gross endoscopic appearance of GERD.

MATERIALS AND METHODS

A prospective cross-sectional study was carried out at a tertiary care hospital in Maharashtra, India, between January 2016 and June 2016. A total of 176 patients referred for upper Gastrointestinal (GI) endoscopy due to dyspeptic symptoms of more than two months duration were selected. BMI (weight in kilograms/square of height in metres) was calculated for all patients and they were classified as normal weight (BMI 18.5 -24.9), overweight (BMI 25-29.9) and obese (BMI≥30). The frequency and severity of GERD symptoms was assessed by a self-administered questionnaire. Data on typical and atypical symptoms of GERD was collected. Upper GI endoscopy was done on all patients. Based on gross endoscopic appearance, the disease was divided as Endoscopy Negative Reflux Disease (ENRD) and true GERD (as per Los Angeles staging system). Association between BMI and frequency, severity and type of symptoms of GERD and also between BMI and gross endoscopic oesophagitis was studied using various statistical tests. All tests were two-tailed with a confidence level of 95%. A p-value < 0.05 was considered to be statistically significant.

RESULTS

Typical symptoms of heartburn and acidic regurgitation were present in 71.6% subjects. The frequency and the severity of the dyspeptic symptoms increased significantly with increasing BMI (p<0.05). Based on the endoscopic gross appearance of the oesophageal mucosa, 48.3% participants had ENRD and 51.7% had erosive disease (GERD). High BMI had a statistically significant relationship with occurrence of both ENRD and GERD (p<0.05) but a statistically insignificant relationship with LA classification system for endoscopic oesophagitis.

CONCLUSION

The prevalence, frequency and severity of symptoms of GERD increases with increase in the BMI. Erosive oesophagitis has significant correlation with increasing BMI, but the staging and classification of endoscopic erosive oesophagitis is independent of the BMI of the patients.

Review of Clinical Spectrum of Gastroesophageal Reflux Disease in a General Population; A Study from South-East Iran

BACKGROUND Gastroesophageal reflux disease (GERD) is one of the most common gastrointestinal problems worldwide. The aim of this study was to evaluate the clinical spectrum, prevalence, and some of the variables that are supposed to be the risk factors of this chronic disorder. METHODS This population- based cross-sectional study was conducted in a one-stage randomized clustered sample of adult inhabitants in Kerman city in 2011-2012. A total of 2265 subjects with age range of 15-85 years were enrolled. Face to face interview was performed for all the subjects. GERD was defined as at least weekly heart burn and/or acid regurgitation during the past year. Association of GERD with factors like demographic variables, medical condition, diet and life habits were analyzed. RESULTS A total of 2265 subjects including 988 (43.8%) male and 1275 (56.3%) female patients were evaluated. The prevalence of GERD was 28%. The prevalence was higher in female patients and with aging. There was also a significant association between GERD and the following risk factors: lower educational level (p <0.0001), higher body mass index (p =003), presence of depression(p<0.0001), and anxiety (p <0=0001). CONCLUSION GERD as a common disorder in our region was seen more in elderly and female patients and was associated with some anthropometric, metabolic, medical conditions, and behavioral habits.

Asia-Pacific consensus on the management of gastro-oesophageal reflux disease: an update focusing on refractory reflux disease and Barrett's oesophagus

OBJECTIVE

Since the publication of the Asia-Pacific consensus on gastro-oesophageal reflux disease in 2008, there has been further scientific advancement in this field. This updated consensus focuses on proton pump inhibitor-refractory reflux disease and Barrett's oesophagus.

METHODS

A steering committee identified three areas to address: (1) burden of disease and diagnosis of reflux disease; (2) proton pump inhibitor-refractory reflux disease; (3) Barrett's oesophagus. Three working groups formulated draft statements with supporting evidence. Discussions were done via email before a final face-to-face discussion. We used a Delphi consensus process, with a 70% agreement threshold, using Grading of Recommendations Assessment, Development and Evaluation (GRADE) criteria to categorise the quality of evidence and strength of recommendations.

RESULTS

A total of 32 statements were proposed and 31 were accepted by consensus. A rise in the prevalence rates of gastro-oesophageal reflux disease in Asia was noted, with the majority being non-erosive reflux disease. Overweight and obesity contributed to the rise. Proton pump inhibitor-refractory reflux disease was recognised to be common. A distinction was made between refractory symptoms and refractory reflux disease, with clarification of the roles of endoscopy and functional testing summarised in two algorithms. The definition of Barrett's oesophagus was revised such that a minimum length of 1 cm was required and the presence of intestinal metaplasia no longer necessary. We recommended the use of standardised endoscopic reporting and advocated endoscopic therapy for confirmed dysplasia and early cancer.

CONCLUSIONS

These guidelines standardise the management of patients with refractory gastro-oesophageal reflux disease and Barrett's oesophagus in the Asia-Pacific region.

Prevalence of gastro-esophageal reflux disease and its risk factors in a community-based population in southern India

Background

The prevalence of gastro-esophageal reflux disease (GERD) varies widely around the world. This study aimed to investigate the prevalence and risk factors of GERD in a general population of southern India.

Methods

An interview-based observational study was carried out in southern India during 2010 and early 2011 using a GERD questionnaire (GerdQ). In total 1072 participants were enrolled using a multi-stage cluster sampling method. Presence of GERD was defined as a score of ≥ 8. Logistic regression models were used to derive odds ratios (ORs) with 95 % confidence intervals (CIs).

Results

The prevalence of GERD was 22.2 % (238/1072) in southern India, and was more common among older subjects and men. Overweight and obese subjects had a dose-dependent increased risk of GERD, compared to those with body mass index less than 25 (multivariate-adjusted OR = 1.4, 95 % CI 1.0–2.0; OR = 2.3, 95 % CI 1.3–4.1, respectively). People residing in urban community were more vulnerable to GERD than those in rural community (multivariate-adjusted OR = 1.8, 95 % CI 1.3–2.5). Similarly, those with a lower educational level appeared to have an increased risk of GERD. Further, those with a habit of pan masala chewing were more likely to develop GERD compared with those abstained from the habit (multivariate-adjusted OR = 2.0, 95 % CI 1.2–3.2).

Conclusions

GERD is highly prevalent in southern India. Increasing age and BMI, an urban environment, lower educational level, and pan masala chewing appear to be risk factors of GERD symptoms for the studied population.

Prevalence of gastroesophageal reflux disease in children, adults, and elderly in the same community

BACKGROUND AND AIM

The prevalence of gastroesophageal reflux disease (GERD) in adults is increasing in Japan as well as worldwide likely due to increasing obesity and the decreasing rate of Helicobacter pylori infection. However, data regarding the prevalence of GERD in children and adolescents in Japan are lacking. We investigated the prevalence of GERD in children, adults, and elderly living in the same community.

METHODS

We surveyed employees of Shimane University Hospital and a related facility and their families using the Gastroesophageal Reflux Disease Questionnaire (GerdQ) and Izumo Scale instruments with demographic information (age, sex, body height, and body weight) and information regarding concurrent medication being taken for GERD. The presence of GERD was defined as a GerdQ score of ≥ 8.

RESULTS

A total of 1859 subjects (771 males, 1088 females; 6-96 years old) were eligible for assessment. The prevalence of GERD in those under 20 years old was 4.4%, which was approximately one third of the rate in adults (11.6%). GERD prevalence was closely associated with obesity in adults, but not in subjects under 20 years old. GERD and other gastrointestinal symptoms frequently overlapped in both adults and younger subjects.

CONCLUSION

We found that the prevalence of GERD in subjects under 20 years of age was lower than that in adults and not associated with obesity. Nevertheless, it is important to be aware of symptoms such as heartburn and/or regurgitation when children and adolescents seek routine clinical care.

Smoking status and prevalence of upper gastrointestinal disorders

BACKGROUND

Lifestyle and environmental factors affecting upper gastrointestinal (GI) disorders are different in developing countries than those in developed nations.

OBJECTIVE

This study aimed to examine the association between smoking status and upper GI disorders among a large group of the Iranian adult population.

METHODS

This cross-sectional study was conducted among 1,933 adult men in Isfahan, Iran. Smoking status was assessed by a self-administered questionnaire. Required information on GI health was collected through the use of the validated ROME III questionnaire. Individuals who reported having heartburn sometimes, often, or always in the last 3 months were considered as having epidemiologic gastroesophageal reflux disease (GERD), and those who reported having heartburn often or always were considered as having clinical GERD. Subjects who reported having functional dyspepsia (FD) symptoms (based on the ROME III criteria) sometimes, often, or always in the last 3 months were considered as having epidemiologic FD, and those who reported having these disorders often or always were considered as having clinical FD.

RESULTS

Smoking was prevalent among 7.8% of the study population. FD and GERD was prevalent among 12.6% (n = 244) and 22.3% (n = 432), respectively. Smoking was not associated with GERD by either the epidemiologic or clinical definition. Although the association between smoking and FD (epidemiologic definition) was not statistically significant, smokers had an 83% higher risk of suffering from clinical FD compared with nonsmokers after taking potential confounders into account [odds ratio (OR) = 1.83, 95% CI: 1.12-3.00; p = 0.01]. Smokers had a 57% higher risk for epidemiologic postprandial fullness (OR = 1.57, 95% CI: 1.05-2.33; p = 0.02) and a 92% higher risk for clinical epigastric pain compared with nonsmokers (OR = 1.92, 95% CI: 1.02-3.62; p = 0.04). We found no significant association between smoking and severity of upper GI disorders.

CONCLUSION

This large population-based study indicated that smoking was not associated with GERD and epidemiologic FD. However, smoking was significantly associated with clinical FD, postprandial fullness, and epigastric pain.

Gastroesophageal reflux disease: diagnosis and patient selection

Gastroesophageal reflux disease (GERD) has a high prevalence worldwide. Recent reports have noted a high prevalence even in Asian countries. GERD significantly affects the quality of life and can present with a wide variety of symptoms. Not all reflux is acid, and non-acid reflux disease can be more difficult to diagnose and can lead to a variety of extra-esophageal symptoms. Although proton pump inhibitors (PPIs) are effective in the majority of patients, but they are not without side effects, and their effect often diminishes with time. For patients who do not desire to be on long-term PPIs or have incomplete symptom resolution with medication, various endoscopic and minimally invasive treatment modalities are now available. The etiology of GERD can be multifactorial including dysfunctional LES, presence of a hiatal hernia, and transient lower esophageal sphincter relaxations (TLESRs). We hence believe that the treatment should be individualized to the cause of the reflux. In the following review, we describe the etiology of reflux disease and attempt to lay a framework for the diagnosis and selection of patients for the various interventions available for treatment, along with their evidence base.

Study of gastro-oesophageal reflux disease in patients with mild-to-moderate chronic obstructive pulmonary disease in India

BACKGROUND AND OBJECTIVE

To study the incidence and pattern of gastro-oesophageal reflux disease (GORD) in patients with mild-to-moderate chronic obstructive pulmonary disease (COPD) using dual-probe 24-h oesophageal pH recording.

METHODS

This was a prospective study of 50 patients with mild-to-moderate stage COPD based on the Global Initiative for Chronic Obstructive Lung Disease (GOLD) guidelines. A detailed history of illness along with spirometry was done in all patients. In the study group, reflux symptoms were measured using a validated scoring system. All the patients underwent oesophageal manometry and dual-probe 24-h oesophageal pH recording.

RESULTS

Symptoms of gastro-oesophageal reflux were present in 38 patients. Twenty-four-hour oesophageal pH monitoring revealed pathological reflux in 31 out of 38 symptomatic and 8 out of 12 asymptomatic patients. The overall rate of GORD was 78% in our study. Only distal GORD was observed in 11 (28.9%), and both distal and proximal GORD was observed in 20 (52.6%) out of the 38 symptomatic subjects. In the remaining 12 asymptomatic patients, eight had GORD. Distal GORD was present in six (50%) patients, and two (16.6%) had both distal and proximal GORD in this group. Isolated proximal GORD was not observed in any patient.

CONCLUSIONS

There is an increased occurrence of GORD in patients with even mild-to-moderate COPD.

Population-based assessment of heartburn in urban Black Americans

Prevalence data for heartburn in the urban Black American community is lacking. In order to estimate prevalence for this community, we analyzed data from an ongoing cohort study in progress at our hospital. Comprehensive interviews allowed for exploration of factors associated with heartburn. Complex, stratified sampling design was the method used. Survey invitations are hand-delivered to random blocks in a single zip code tabulation area. One member per eligible household is invited to complete a computer-based survey. Heartburn was defined as ≥ 3 days/week of symptoms as defined by the Montreal Definition and Classification of gastroesophageal reflux disease. Scaling and weighting factors were utilized to estimate population level prevalence. Multivariate logistic regression was used to identify independent predictor variables for heartburn. Enrolled 379 participants corresponding to a weighted sample size of 22,409 (20,888-23,930) citizens. Demographic characteristics of the sample closely matched those of the entire targeted population. Overall, the weighted prevalence of heartburn ≥ 3 times per week was 17.6% (16.4-18.8%). Variables independently associated with heartburn were body mass index, daily caloric and fat intake, diabetes mellitus (odds ratio = 2.95; 2.59-3.36), cigarette smoking, and alcohol consumption (odds ratio = 2.55; 2.25-2.89). Factors inversely associated included illicit drug use and increased physical activity. Waist : hip ratio showed no relationship. The prevalence of heartburn ≥ 3 times per week is high in the Black American community. Adverse lifestyle behaviors showed particularly important associations. Our study needs to be replicated in other communities with similar demographics.

Impact of laparoscopic Nissen's fundoplication on response of disease specific symptoms and quality of life

The aim of this study is to establish responsiveness of gastroesophageal reflux disease (GERD) symptom score, quality of life SF-36 score in GERD with relation to oesophageal manometry and upper gastrointestinal endoscopy following laparoscopic Nissen's fundoplication (LNF). Interventional prospective study was done enrolling 77 patients of GERD who respond to proton pump inhibitor (PPI) and have undergone LNF, strict diagnostic criteria were followed with GERD score, upper gastrointestinal endoscopy, oesophageal manometry, and endoscopically negative patients have further undergone 24-h pH study. Follow-up was done at 12 and 24 months by GERD score, SF-36 score, endoscopy, oesophageal manometry. GERD score shows significant difference in pre-operative and post-operative score with P value <0.001 except dysphagia. Post-LNF improvement in GERD score is consistent with improvement in lower oesophageal sphincter (LES) pressure at 12 months. All dimensions in quality of life SF-36 show significant difference in pre-operative and post-operative score at 12 months with P value <0.001. Results are consistent at 24 months. Oesophagitis was decreased from 40.2 to 11.6 % as well as it showed down grading on endoscopy in post-operative period. Out of three patients of complete disruption of wrap, two patients underwent redo surgery and showed improvement. In properly diagnosed PPI respondent patients by GERD score, LNF has got improvement in GERD score, quality of life in all dimensions of SF-36 score in relation to improvement with LES pressure and oesophagitis.

Questionnaire based gastroesophageal reflux disease (GERD) assessment scales

Questionnaire based assessment scales for gastroesophageal reflux disease (GERD) have been utilized for assessment of the patient's symptomatology, assessment of symptom severity and frequency, assessment of health-related quality of life and for assessment of response to treatment. A multitude of unidimensional and multidimensional questionnaires exist for making symptom assessment and monitoring quality of life in GERD. Many of the scales meet some of the parameters of an ideal evaluative GERD specific assessment instrument. Yet, there are certain shortcomings and challenges which are faced in development of GERD questionnaires. This review discusses the features of an ideal symptom assessment instrument, examines the strengths and weaknesses of currently available questionnaires.

Epidemiology and symptom profile of gastroesophageal reflux in the Indian population: report of the Indian Society of Gastroenterology Task Force

BACKGROUND

Gastroesophageal reflux disease (GERD) and its complications are thought to be infrequent in India; there are no data from India on the prevalence of and risk factors for GERD. The Indian Society of Gastroenterology formed a task force aiming to study: (a) the frequency and profile of GERD in India, (b) factors including diet associated with GERD.

METHODS

In this prospective, multi-center (12 centers) study, data were obtained using a questionnaire from 3224 subjects regarding the frequency, severity and duration of heartburn, regurgitation and other symptoms of GERD. Data were also obtained regarding their dietary habits, addictions, and lifestyle, and whether any of these were related or had been altered because of symptoms. Data were analyzed using univariate and multivariate methods.

RESULTS

Two hundred and forty-five (7.6%) of 3224 subjects had heartburn and/or regurgitation at least once a week. On univariate analysis, older age (OR 1.012; 95% CI 1.003-1.021), consumption of non-vegetarian and fried foods, aerated drinks, tea/coffee were associated with GERD. Frequency of smoking was similar among subjects with or without GERD. Body mass index (BMI) was similar in subjects with and without GERD. On multivariate analysis, consumption of non-vegetarian food was independently associated with GERD symptoms. Overlap with symptoms of irritable bowel syndrome was not uncommon; 21% reported difficulty in passage of stool and 9% had mucus in stools. About 25% of patients had consulted a doctor previously for their gastrointestinal symptoms.

CONCLUSION

7.6% of Indian subjects have significant GERD symptoms. Consumption of non-vegetarian foods was an independent predictor of GERD. BMI was comparable among subjects with or without GERD.
