Abstract
Up to 79% of IBS patients report gastroesophageal reflux disease (GERD) symptoms, and up to 71% of GERD patients report irritable bowel syndrome (IBS) symptoms. There are two principal hypotheses for the common presence of IBS symptoms in GERD patients. The first theory suggests that GERD and IBS overlap in a significant number of patients. The second theory suggests that IBS-like symptoms are part of the spectrum of GERD manifestation. The first theory is supported by genetic studies and similarities in gastrointestinal sensory-motor abnormalities potentially due to general gastrointestinal disorder of smooth muscle or sensory afferents. The other theory is primarily supported by studies demonstrating improvement of IBS-like symptoms in GERD patients receiving anti-reflux treatment. The close relationship between GERD and IBS could be explained by either GERD affecting different levels of the GI tract or a high overlap rate between GERD and IBS due to similar underlying GI dysfunction.

Abstract
BACKGROUND Upper gastrointestinal symptoms impose a substantial illness burden and management costs. Understanding perceptions and reasons for seeking healthcare is a prerequisite for meeting patients' needs effectively. AIM To review systematically findings on consultation frequencies for gastro-oesophageal reflux disease (GERD) and dyspepsia and patients' reasons for consultation. METHODS Systematic literature searches. RESULTS Reported consultation rates ranged from 5.4% to 56% for GERD and from 26% to 70% for dyspepsia. Consultation for GERD was associated with increased symptom severity and frequency, interference with social activities, sleep disturbance, lack of timetabled work, higher levels of comorbidity, depression, anxiety, phobia, somatization and obsessionality. Some consulted because of fears that their symptoms represented serious disease; others avoided consultation because of this. Inconsistent associations were seen with medication use. Patients were less likely to consult if they felt that their doctor would trivialize their symptoms. Few factors were consistently associated with dyspepsia consultation. However, lower socio-economic status and Helicobacter pylori infection were associated with increased consultation. CONCLUSION Patients' perceptions of their condition, comorbid factors and external reasons such as work and social factors are related to consultation rates for GERD. Awareness of these factors can guide the clinician towards a more effective strategy than one based on drug therapy alone.

Abstract
BACKGROUND There has been no report on the response to proton pump inhibitor (PPI) therapy and on-demand or the relapse rate of non-erosive reflux disease (NERD) and erosive oesophagitis in Korea. AIM To compare the risk factors, clinical symptoms and PPI responses between patients with erosive oesophagitis and NERD patients. METHODS A survey was performed prospectively in the erosive oesophagitis (205 patients) and NERD group (200 patients). Clinical symptoms, risk factors and PPI responses were analysed. On-demand therapy and the relapse rate of GERD symptoms were investigated during a one-year follow-up. RESULTS BMI > or = 25 (OR 3.0, 95% CI 1.1-8.3), alcohol use (OR 2.9, 95% CI 1.0-8.3), hiatal hernia (OR 5.0, 95% CI 1.2-20) and triglyceride > or =150 mg/dL (OR 4.0, 95% CI 1.7-10) were more common in the erosive oesophagitis group than in the NERD group by multivariate analysis. The ratio of oesophageal to extra-oesophageal symptoms was higher in the erosive oesophagitis group compared with the NERD group (P < 0.001). The PPI response rates at 8 weeks were different (P = 0.02); refractory rates were higher in the NERD group (16.7%) compared with the erosive oesophagitis group (6.0%). However, there was no significant difference between the two groups in on-demand therapy or the relapse rate. CONCLUSION These results suggest that the underlying pathogenic mechanisms of erosive oesophagitis and NERD are distinct.

Abstract
Objective.To determine the frequency and severity of gastrointestinal (GI) symptoms in patients with fibromyalgia (FM).Methods.We included 152 women with FM (mean age 45.4 ± 12.2 yrs), 98 women with rheumatoid arthritis (RA; mean age 45.5 ± 12.3 yrs), and 60 healthy female controls (mean age 44 ± 11.3 yrs). All patients were questioned about the severity of their chronic widespread pain, symptoms of FM, symptoms of dyspepsia, using a visual analog scale (VAS), and anxiety-depression scale. Patients were asked self-reported (yes/no), symptom-based (≥ 2 criteria) constipation and severity of constipation questions, and about the severity of quality of life (QOL) disturbance secondary to dyspepsia and constipation.Results.Patients with FM had higher symptom severities for belching, reflux, bloating, sour taste, and vomiting than patients with RA and controls (all p values < 0.01). Patients with FM had significantly more dyspepsia-related QOL disturbances than the other 2 groups (p < 0.01). FM and RA patients had more frequent self-reported constipation than controls (respectively, 42.1%, 48%, 21.7%; p < 0.01). The frequency of symptom-based constipation was significantly higher in the RA group (49%) than in FM (29.6%) and control groups (23.3%) (p < 0.01). Constipation-related QOL disturbance was significantly higher in patients with FM than in controls (p < 0.01).Conclusion.In patients with FM, the severity scores of dyspepsia symptoms, constipation, and dyspepsia-related QOL disturbance were higher than in patients with RA and controls. The higher GI symptom severity in patients with FM might have negative effects on their QOL.

Abstract
The increasing interest in research in irritable bowel syndrome (IBS) and other functional gastrointestinal disorders (FGIDs), taken together with the growing sophistication of communication technology, makes cross-cultural, multi-national research a feasible endeavour. The aim of this study is to encourage collaborative cross-cultural studies in FGIDs by discussing relevant methodological issues, and by suggesting potential areas in which cross-cultural research can make a significant contribution to the understanding of FGIDs and to patient care. To this end, methodological issues related to cross-cultural research and competences required for its conduct are presented together with a critique of published studies and recommendations for future research in the area. The term 'cross-cultural' research in FGIDs is usually applied to the results of prevalence studies, for example comparative studies of IBS prevalence in different countries and ethnic groups. The validity of these comparisons is impacted negatively by the lack of uniformity in research methods. In addition to prevalence studies, cross-cultural research can make a significant contribution in areas such as molecular biology, genetics, psychosocial factors, symptom presentation, extra-intestinal comorbidity, diagnosis and treatment, determinants of disease severity, healthcare utilization, and health-related quality of life, all issues that can be affected by culture, ethnicity and race. Well-designed and implemented cross-cultural studies can advance our knowledge in many FGID-related areas ranging from epidemiology through psychosocial factors, pathophysiological mechanisms and therapeutics. These studies, conducted by investigators with competence in cross-cultural research methodology, can advance our understanding of the FGIDs and contribute to improved patient care.

Abstract
AIM: To investigate the prevalence and risk factors of gastroesophageal reflux disease (GERD) symptoms in Qashqai migrating nomads with a different life style in Fars province, southern Iran.
METHODS: In summer 2006, 748 Qashqai migrating nomads aged 25 years or more were enrolled using a multiple-stage stratified cluster random sampling method. A questionnaire consisting of demographic characteristics, lifestyle and GERD symptoms (heartburn, regurgitation, chest pain, dysphagia, hoarseness and cough) as completed for each subject.
RESULTS: The questionnaire was completed in 717 subjects. The prevalence rate of GERD, defined as reflux occurring at least one time per week in the preceding year, was 33% (237 subjects). The prevalence was higher in older individuals (36.0% vs 28.9%, P < 0.05) and in those with other gastrointestinal complaints (51.0% vs 27.8%, P < 0.001), but not different in obese and non-obese subjects. It was also higher in those consuming fruits and vegetables more than once a week (36.2% vs 17.3%, P < 0.001). GERD had a positive correlation with smoking (42.1% vs 27.8%, P < 0.001), but a negative relation with non-alcoholic beverages. The association between GERD and non-steroidal anti-inflammatory drugs (NSAIDs) consumption was also significant (40.2% vs 25.4%, P < 0.001).
CONCLUSION: The prevalence of GERD (33%) is very high in Qashqai migrating nomads which may be due to a lower socioeconomic and educational level of these people and difference in the life style. Older age, frequent consumption of fruits and vegetables, smoking and NSAIDs are risk factors for GERD in this population.

Abstract
BACKGROUND A growing number of studies have shown the impact of psychological comorbidities on gastro-oesophageal reflux disease (GERD) patients' symptom reports and healthcare-seeking behaviour. AIM To review the reported relationship between GERD and psychological comorbidity. METHODS Review of the literature on GERD and psychological comorbidity. RESULTS Psychological comorbidity is common among GERD patients and appears to afflict all GERD phenotypes. Sexual and physical abuse is also common in GERD patients. Stress enhances perception of oesophageal acid exposure. Treatment for GERD, especially in those who are not responsive to antireflux treatment, may require further evaluation for psychological comorbidity. CONCLUSIONS Psychological comorbidity is very common in GERD patients and is likely to play an important role in response, or failure of response, to proton pump inhibitor treatment.

Abstract
The prevalence of gastroesophageal reflux disease (GERD) in China is lower than that in the Western countries, but appears to be increasing. The aim of this pilot study was to evaluate the prevalence of GERD in Shanghai, China, and to explore which population characteristics where associated with GERD. A sample of 1200 adult inhabitants of Shanghai, selected using randomized, stratified, multi-stage sampling, completed Mandarin translations of the Reflux Disease Questionnaire and GERD Impact Scale. Potential risk factors for GERD were examined by nested case-control analysis, using Cochran-Armitage trend testing and logistic regression analysis. The response rate was 86.2%; 919 responses were suitable for analysis. The prevalence of GERD, defined as heartburn and/or regurgitation of any frequency during the previous week, was 6.2% in Shanghai. Obesity and urban dwelling were associated with GERD (odds ratio 3.4, 95% confidence interval 1.3-9.3; and odds ratio 3.6, 95% confidence interval 1.2-10.4, respectively). The prevalence of GERD in Shanghai agreed with previous Chinese studies. GERD in Shanghai was associated with obesity and residency in an urban environment.

Abstract
Gastroesophageal reflux disease (GERD) is a common chronic disorder that is associated with a huge economic burden in the western countries and significantly decreased quality of life. This review focuses on the various multicultural issues in the epidemiology, pathophysiology, diagnosis, and treatment of GERD. The prevalence of GERD appears to be highest in North America and Europe, whereas epidemiologic data from the Indian subcontinent, Africa, South America, and the Middle East are sparse. A limited number of studies have elucidated ethnic differences in GERD in multiracial populations. African Americans and Asians appear to be at a lower risk for the development of complicated GERD including Barrett's esophagus (BE). Whether the pathophysiology of GERD differs among different populations remains to be answered satisfactorily. It appears that most of the factors involved in the pathogenesis of GERD, as described in western populations, are present in Asians but at a lower scale. The current recommendations for the management of GERD by the American College of Gastroenterology may not meet the need for different ethnic groups or for different geographic regions. Recognition of language barriers in understanding the common terms used to describe reflux symptoms should be borne in mind while treating GERD patients with different ethnic backgrounds. In addition, a universally accepted definition for treatment success in GERD patients is lacking. Given the negative impact on health-related quality of life, significant cost ramifications, and increased risk for BE and esophageal adenocarcinoma, the study of multicultural issues in GERD should be considered.

Abstract
Advances in genetics and genomics during the past decade, including sequencing of the human genome and DNA sequencing technologies, have made it possible to discover the genetic basis for many diseases. With the discovery of multiple genetic loci for gastrointestinal diseases such as Crohn's disease, some have begun to wonder-Could there be a genetic basis for irritable bowel syndrome (IBS)? This article summarizes the evidence for and against a link between genes and IBS. In addition, a gene-environment paradigm is presented to combine the two opposing hypotheses, as IBS may represent a complex genetic disorder that results from the interaction of several genes and environmental risk factors.

Abstract
Previous studies have found no female predominance in irritable bowel syndrome (IBS) in non-Western countries. The aim of the study was to assess the prevalence and correlates of Rome II (IBS) in both sexes in Pakistan. A Population-based survey in a low-income inner city area using questionnaires to diagnose Rome II IBS and assess distress, disability and stressful life events. Data were collected from 880/938 (93%) randomly selected residents. 13.4% of women and 13.1% men met criteria for Rome II IBS; 34 (3.9%) had diarrhoea-predominant, 59 (6.7%) had constipation-predominant IBS and 24 (2.7%) had 'mixed IBS'. In logistic regression analysis, IBS was associated in men with high income (OR = 1.56; 95% CI: 1.05-2.3) and few years of education (OR = 2.17; 95% CI: 1.2-3.9) and in women with being married (OR = 3.6; 95% CI: 1.1-11.9) and stressful life events score (OR = 1.14; 95% CI: 1.01-1.3). Disability was associated with constipation-predominant IBS (OR = 1.99; 95% CI: 1.1-3.6), distress (OR = 1.19; 95% CI: 1.14-1.23) and stressful life events (OR = 1.19; 95% CI: 1.1-1.3). Investigations were more likely in men (54%) than in women (27%) (P = 0.003). These findings suggest that the equal sex ratio of IBS in urban Pakistan could result from a close association between marked distress and IBS in men similar to that found in women in western studies.

Abstract
Gastro-oesophageal reflux disease (GORD) is one of the most common gastrointestinal diseases in the Western world and imposes a heavy burden on society. Although its prevalence in Asia is much lower, there is evidence that this is rapidly rising in Asia. The reported population prevalence of GORD in Eastern Asia ranges from 2.5% to 6.7% for at least weekly symptoms of heartburn and/or acid regurgitation. In general, Asians tend to have a milder spectrum of the disease. Most Asian patients have non-erosive GORD; erosive oesophagitis is less commonly seen than in the Western population. Complicated GORD, such as oesophageal stricture and Barrett's oesophagus, is seldom encountered. The mechanisms of GORD may be different in the Chinese population compared with the Western population. Chest pain is the most predominant extra-oesophageal manifestation of GORD in China, whereas an association with asthma has been shown in Japanese patients. The prevalence of GORD appears to be increasing and possible factors for GORD in Asian populations include Helicobacterpylori infection, obesity and increasing dietary fat intake. The adoption of a Western lifestyle in many developing Asian countries may account for the increasing prevalence of GORD. Proton pump inhibitors remain the most effective medical treatment for GORD. GORD will undoubtedly be a great challenge to clinicians both in primary care and in gastroenterology practice in the Asia-Pacific region in the coming years.

Abstract
BACKGROUND There is a wide range in reported prevalence of irritable bowel syndrome worldwide. From the data appeared recently in medical literatures in China, it seems that the incidence of irritable bowel syndrome in young adults is not dissimilar to the one in the Western countries. AIMS To explore the prevalence and epidemiological variations of irritable bowel syndrome in an undergraduate student population in Southeast China on the basis of the Rome II and Rome III criteria. METHODS All the undergraduate student participants were administered self-report diagnostic measures for irritable bowel syndrome. RESULTS The sex-adjusted prevalence rate of irritable bowel syndrome was 4.7% (Rome II) and 10.4% (Rome III), respectively. When we combined irritable bowel syndrome mixed and irritable bowel syndrome unsubtyped in the Rome III subgroups into one group considering the counterpart in the Rome II subgroups was alternative irritable bowel syndrome, the agreement between the two ways to subdivide these 54 patients who were identified with irritable bowel syndrome by both the two criteria was 81%, with a kappa value of 0.67. By the Rome III criteria, we found a female predominance which was especially attributed to the subtypes of irritable bowel syndrome with constipation and unsubtyped. CONCLUSIONS Our study suggests that, in young adults in Southeast China, changing diagnostic criteria for irritable bowel syndrome from Rome II to Rome III may affect women more than men on not only the overall prevalence rate but also the sex-difference present or not, especially in irritable bowel syndrome with constipation and irritable bowel syndrome unsubtyped subgroups.

Abstract
BACKGROUND Prospective nationwide multicentre studies that have evaluated endoscopic findings and reflux symptoms using a well-designed questionnaire are very rare. AIM To compare the prevalence rates of and risk factors for erosive oesophagitis and non-erosive reflux disease (NERD) in the Korean population. METHODS A gastroscopic examination was performed on 25 536 subjects who visited 40 Healthcare Centers for a health check-up. A gastro-oesophageal reflux questionnaire and multivariate analysis were used to determine the risk factors for erosive oesophagitis and NERD. RESULTS 2019 (8%) and 996 subjects (4%) had erosive oesophagitis and non-erosive reflux disease, respectively; only 58% of subjects with erosive oesophagitis had reflux symptoms. Multivariate analysis showed that the risk factors for erosive oesophagitis and NERD differed, i.e. those of erosive oesophagitis were male, a Helicobacter pylori eradication history, alcohol, body mass index > or =25 and hiatal hernia. In contrast, the risk factors for NERD were female, age <40 and > or =60 vs. 40-59 years, body mass index <23 and a monthly income <$1000, glucose > or =126 mg/dL, smoking, a stooping posture at work and antibiotic usage. CONCLUSIONS The prevalence rates of erosive oesophagitis and NERD were 8% and 4%, respectively, in Korean health check-up subjects. The risk factors for erosive oesophagitis and NERD were found to differ, which indicates that their underlying pathogeneses are distinct.

Abstract
OBJECTIVES Among individuals who satisfy diagnostic criteria for both major depressive disorder (MDD) and irritable bowel syndrome (IBS), little is known about the role of familial tendency and environmental influences in disease susceptibility. Therefore, we aimed to examine if there is a genetic component to the co-occurrence of MDD and IBS in participants from the population-based Swedish Twin Registry. METHODS We implemented a nested case-control analysis and a co-twin control analysis. IBS cases were ascertained using an adapted version of the Rome II criteria and MDD cases were assessed using a shortened version of the Computerized International Diagnostic Interview. The case-control analysis included individuals with complete covariate information (N = 29,616), and adjusted for twin pair, 3-yr age band, and sex. The co-twin control analysis considered 288 twin pairs discordant for IBS. Odds ratios (OR) and 95% confidence intervals (CI) were estimated using generalized estimating equations for the case-control analysis and conditional logistic regression for the co-twin control analysis. RESULTS In all analyses, comorbid disorders of chronic widespread pain, chronic fatigue-like illness, and MDD were more common in IBS cases than controls. In the case-control analysis, individuals with IBS had an increased odds of MDD (OR 2.7, 95% CI 2.3-3.2). In the co-twin analysis, the association was similar (OR 2.2, 95% CI 1.5-3.3) when both MZ and DZ twins were used, and larger among only MZ twins (OR 3.2, 95% CI 1.7-6.1). CONCLUSIONS From this analysis, we found no evidence that genetic and family environmental factors explain the association between MDD and IBS. Rather, one of these disorders appears to be part of the disease-causing sequence of events, or biologic disease pathway, for the other disorder. However, it was not possible to evaluate the timing of onset between MDD and IBS in this study.

Abstract
BACKGROUND The association between psychiatric disorders and gastro-oesophageal reflux symptoms is uncertain, and few population-based studies are available. AIM To examine the association between psychiatric and psychological factors and reflux symptoms. METHODS Population-based, cross-sectional, case-control study based on two health surveys conducted in the Norwegian county Nord-Trondelag in 1984-1986 and 1995-1997. Reflux symptoms were assessed in the second survey, including 65,333 participants (70% of the county's adult population). 3153 subjects reporting severe reflux symptoms were defined as cases and 40,210 subjects without symptoms were defined as controls. Data were collected in questionnaires. Odds ratio with 95% confidence intervals were estimated using unconditional logistic regression, in adjusted models. RESULTS Subjects reporting anxiety without depression had a 3.2-fold (95% CI: 2.7-3.8) increased risk of reflux, subjects with depression without anxiety had a 1.7-fold (95% CI: 1.4-2.1) increased risk and subjects with both anxiety and depression had a 2.8-fold (95% CI: 2.4-3.2) increased risk, compared to subjects without anxiety/depression. We observed a weak inverse association between one measure of covert coping and risk of reflux and a weak positive association between another coping measure and risk of reflux. CONCLUSIONS This population-based study indicates that anxiety and depression are strongly associated with reflux symptoms, while no consistent association regarding coping and reflux was found.

Abstract
OBJECTIVE Patients suffering from irritable bowel syndrome (IBS) have more somatic and psychiatric comorbidity and use more health-care services for comorbid conditions than do other patients. Little is known about the frequency of comorbid symptoms among IBS sufferers in the general population and their influence on use of health-care facilities. The objective of this study was to compare the frequency of somatic and psychiatric symptoms between IBS sufferers and controls in the general population, and to study how comorbidity rates are distributed among consulters and non-consulters and how they predict the use of health care-services. MATERIAL AND METHODS By means of a questionnaire sent to 5000 randomly selected adults IBS was identified according to the Rome II criteria. The questionnaire also covered upper GI symptoms, non-GI somatic symptoms, depression and anxiety. A logistic regression analysis with 26 variables was carried out to determine the independent predictors of health-care seeking for GI and non-GI complaints. RESULTS The response rate was 73% and prevalence of IBS 5.1% (95% CI 4.4-5.8%). Dyspeptic symptoms, somatic extra-GI symptoms and psychiatric symptoms were reported by 45%, 69% and 51% of IBS sufferers, respectively, and 6%, 35% and 27%, of controls, respectively. Visiting a physician because of GI complaints was associated with disturbing abdominal symptoms, but not with depression or anxiety. Of the present GI conditions, only dyspeptic symptoms were associated with an increased consultation rate also for non-GI complaints. CONCLUSIONS In the general population, both IBS consulters and non-consulters demonstrate high rates of comorbidity. Seeking health care for abdominal complaints is associated with abdominal symptoms rather than psychiatric comorbidity.

Abstract
OBJECTIVES Revisions of the diagnostic criteria for irritable bowel syndrome have led to varying prevalence estimates. The Rome III criteria require a lower symptom frequency than Rome II (at least 10% of the time for Rome III, compared with at least 25% of the time for Rome II). In an epidemiological survey of a representative sample of Israeli adults using Rome II, we reported the prevalence for irritable bowel syndrome as 2.9%. The official Rome II integrative questionnaire, used for that study, enables a close approximation of Rome III rates, facilitating a retrospective comparison of these criteria. METHODS A representative sample of 1000 adults was interviewed with a validated Hebrew version of the official Rome II integrative questionnaire. The data were re-evaluated retrospectively to compare the Rome II results with a close approximation of the new Rome III criteria. RESULTS The prevalence rates for irritable bowel syndrome were 2.9 and 11.4%, respectively, for Rome II and Rome III. The corresponding consultation rates were 57.1 and 41.7%, indicating that the more strict Rome II criteria may select out a group of patients with more severe disease or greater psychosocial problems. Women made up 71.4% of irritable bowel syndrome by Rome II and 62.5% by Rome III. CONCLUSIONS In the present retrospective study, the prevalence rate for irritable bowel syndrome in our population is significantly higher by Rome III compared with Rome II. Rome III may more closely reflect the socioeconomic burden of irritable bowel syndrome compared with the overly strict Rome II. Prospective comparative studies should be conducted to confirm these results.

Abstract
BACKGROUND Gastro-oesophageal reflux disease and irritable bowel syndrome are common diseases which may be related. AIM To examine the association between gastro-oesophageal reflux disease and irritable bowel syndrome in Chinese population in Hong Kong. METHODS Randomly selected ethnic Chinese were invited to participate in a telephone survey in 1996. Gastro-oesophageal reflux disease was defined as subjects having heartburn and/or acid regurgitation once weekly or more. Irritable bowel syndrome was diagnosed according to the Rome I criteria. The association between gastro-oesophageal reflux disease and irritable bowel syndrome was calculated using a statistical model which allows the odds ratio to be measured. RESULTS One thousand six hundred and forty-nine subjects completed the interview (response rate 62%). The population prevalence of gastro-oesophageal reflux disease and irritable bowel syndrome were 5% and 4%, respectively. Thirteen per cent of subjects with gastro-oesophageal reflux disease and 11% with irritable bowel syndrome suffered from both gastro-oesophageal reflux disease and irritable bowel syndrome. The OR of having gastro-oesophageal reflux disease and irritable bowel syndrome together was estimated to be 3 (95% CI: 1.05, 6.27) indicating a positive association between the two diseases. This association occurred predominantly in male subjects [OR = 9.3, (95% CI: 2.3, 26.2)] but not as strong in females [OR = 1.5, (95% CI: 0.3, 4.3)]. Younger subjects were statistically more prone to the two diseases. CONCLUSIONS There is a positive association between gastro-oesophageal reflux disease and irritable bowel syndrome, and their association occurs predominantly in male subjects.

Abstract
There is a perception that the prevalence of gastroesophageal reflux disease (GERD) is increasing, but few studies have directly tackled this issue. By using a systematic approach, this review aimed to assess objectively whether the prevalence of GERD is changing with time. First, population-based studies that reported the prevalence of at least weekly heartburn and/or acid regurgitation were subjected to a time-trend analysis with a Poisson regression model. Second, population-based studies reporting the prevalence of GERD symptoms at 2 time points in the same source population were reviewed. Third, longitudinal studies that charted the prevalence of GERD symptoms and esophagitis in primary and secondary care were examined. The Poisson model revealed a significant (P < .0001) trend for an increase in the prevalence of reflux symptoms in the general population over time. Separately, significant increases with time were found for North America (P = .0005) and Europe (P < .0001) but not Asia (P = .49). Studies of the same source population over time indicated an increase in the prevalence of GERD in the U.S., Singapore, and China but not Sweden. An increase in the prevalence of GERD or esophagitis was found in the majority of longitudinal studies. There is evidence that the prevalence of GERD has increased during the past 2 decades. If this trend continues, it could contribute to the rapidly increasing incidence of more serious complications associated with GERD, such as esophageal adenocarcinoma, as well as costs to healthcare systems and employers.

Abstract
Asian irritable bowel syndrome (IBS) studies not only confirm the truth of this functional disorder but also describe the current disease situation of this continent, with its variable socioeconomic backgrounds. Most Asian community IBS prevalence is within 5-10%, regardless of gender or ethnic character. As well as meeting the main Rome II criteria, Asian IBS subjects also have many minor symptoms. Thus this recommendation remains useful to diagnose Asian IBS. Also, female patients commonly express constipation-predominant (C-) symptoms. Extra-colonic symptoms are common in Asia, for example dyspepsia, insomnia and irritable urinary bladder. Asian IBS subjects do experience psychological disturbances including anxiety, depression, agoraphobia and neuroticism. Accordingly, their quality of life is poor and there is absenteeism leading to excessive physician visits. Abnormal gut motor and sensory functions have been indicated among the Asian IBS subjects. Now, there is evidence of altered colonic neuroimmune function leading to gut hypersensitivity and dysmotility. An Asia-Pacific trial also confirmed tegaserod efficacy on female C-IBS subjects. More than 90% of nurses have very limited IBS knowledge, and are unable even to explain it clearly. In conclusion, Western recommended criteria clearly diagnose Asian IBS and many factors are mutual leading to IBS. Current IBS treatments remain useful but additional reeducation for medical professionals appears to be needed.

Abstract
BACKGROUND Irritable bowel syndrome (IBS) is a common functional gastrointestinal disorder in the West. But information on the prevalence of IBS in Asia is still lacking, especially in Korea. Therefore, the aims of the present study were to estimate the prevalence of IBS in the general population of Korea and also to investigate characteristics of IBS and health-care-seeking behavior of IBS patients. METHODS Telephone interview survey was conducted by Gallup, Korea using a validated questionnaire based on the Rome II criteria. The response rate of the telephone interview survey was 25.2% (n = 1066, 535 male and 531 female responders). A random sample of gender and age (between 18 and 60 years), based on a per capita ratio was obtained. RESULTS Among 1066 subjects, the prevalence of IBS was 6.6% (70 subjects; 7.1%, male; 6.0%, female). The difference in IBS prevalence by gender was not significant. The prevalence was higher among those in their 20s (P = 0.036). Among 70 subjects with IBS, 10/20 IBS subjects sought health care due to abdominal pain. Among the risk factors of IBS, marital status had a significant difference; the following risk factors are arranged in descending order: age (odds ratio [OR]: 1.38, 95% confidence interval [CI]: 0.85-2.25), alcohol intake (OR: 1.38, 95%CI: 0.81-2.35), gender (OR: 1.19, 95%CI: 0.73-1.94), demographics (OR: 1.09, 95%CI: 0.53-2.25), income (OR: 0.88, 95%CI: 0.54-1.45), education level (OR: 0.81, 95%CI: 0.46-1.40), smoking (OR: 0.64, 95%CI: 0.37-1.12), and marital status (OR: 0.59, 95%CI: 0.35-0.99). CONCLUSIONS The prevalence of IBS in the Korean population is 6.6%, and the male:female ratio is similar. Also, IBS is more frequent in younger subjects. Irritable bowel syndrome subjects visited a physician mostly due to abdominal pain.

Abstract
AIM: To investigate the optimal strategy to treat dyspeptic patients in primary care.
METHODS: Dyspeptic patients presenting to primary care outpatient clinics were randomly assigned to: (1) empirical endoscopy, (2) H pylori test-and-treat, and (3) empirical prokinetic treatment with cisapride. Early endoscopy was arranged if patients remained symptomatic after 2 wk. Symptom severity, quality-of-life (SF-36) as well as patient preference and satisfaction were assessed. All patients underwent endoscopy by wk 6. Patients were followed up for one year.
RESULTS: Two hundred and thirty four patients were recruited (163 female, mean age 49). 46% were H pylori positive. 26% of H pylori tested and 25% of empirical prokinetic patients showed no improvement at wk 2 follow-up and needed early endoscopy. 15% of patients receiving empirical cisapride responded well to treatment but peptic ulcer was the final diagnosis. Symptom resolution and quality-of-life were similar among the groups. Costs for the three strategies were HK$4343, $1771 and $1750 per patient. 66% of the patients preferred to have early endoscopy.
CONCLUSION: The three strategies are equally effective. Empirical prokinetic treatment was the least expensive but peptic ulcers may be missed with this treatment. The H pylori test-and-treat was the most cost-effective option.

Abstract
BACKGROUND Gastro-oesophageal reflux disease has wide-ranging effects on patients' lives. AIM To review systematically the effects of gastro-oesophageal reflux disease on work productivity. METHODS Studies of gastro-oesophageal reflux disease and work productivity were identified in a systematic literature search and their results were valued in US dollars using the human capital method. Work productivity loss was defined as absence from work (absenteeism) plus reduced effectiveness while working (presenteeism). RESULTS Eight eligible studies were included. Reported work productivity loss among individuals with gastro-oesophageal reflux disease ranged from 6% to 42% and was primarily because of presenteeism (6-40%) rather than absenteeism (<1% to 7%). Reported losses were greatest in patients experiencing sleep disturbance because of gastro-oesophageal reflux disease, and lowest in individuals from the general population taking appropriate prescription medication. Work productivity impairment correlated with symptom severity and responded to acid-suppressive therapy. Assuming a 40-h working week and average wages in the US, the weekly mean productivity loss per employee with gastro-oesophageal reflux disease can be estimated between 2.4 (62 dollars) and 16.6 h (430 dollars), depending on the population studied. CONCLUSIONS Gastro-oesophageal reflux disease has a substantial impact on employee productivity, primarily by impairing productivity while working. Further studies are needed to confirm that this impact can be decreased by acid-suppressive therapy.

Abstract
Dyspepsia refers to group of upper gastrointestinal symptoms that occur commonly in adults. Dyspepsia is known to result from organic causes, but the majority of patients suffer from non-ulcer or functional dyspepsia. Epidemiological data from population-based studies of various geographical locations have been reviewed, as they provide more realistic information. Population-based studies on true functional dyspepsia (FD) are few, due to the logistic difficulties of excluding structural disease in large numbers of people. Globally, the prevalence of uninvestigated dyspepsia (UD) varies between 7% - 45%, depending on definition used and geographical location, whilst the prevalence of FD has been noted to vary between 11% - 29.2%. Risk factors for FD have been shown to include females and underlying psychological disturbances, whilst environmental/ lifestyle habits such as poor socio-economic status, smoking, increased caffeine intake and ingestion of non-steroidal anti-inflammatory drugs appear to be more relevant to UD. It is clear that dyspepsia and FD in particular are common conditions globally, affecting most populations, regardless of location.

Abstract
AIM: Recently, drinking load tests with water or nutritional beverages have been proposed as diagnostic tools for functional dyspepsia (FD), therefore we sought to reproduce if these tests can discriminate between FD patients and controls in a Mexican population.
METHODS: Twenty FD-Rome II patients were matched by age and gender with 20 healthy controls. All underwent both drinking tests at a 15 mL/min rate, randomly, 7 d apart. Every 5 min within each test, four symptoms were evaluated (satiety, bloating, nausea and pain) by Likert scales. Maximum tolerated volume (MTV) was defined as the ingested volume when a score of 5 was reached for any symptom or when the test had to be stopped because the patients could not tolerate more volume. Sensitivity and specificity were analyzed.
RESULTS: FD patients had higher symptom scores for both tests compared to controls (water: t = 4.1, P = 0.001<0.01; Nutren®: t = 5.2, P = 0.001<0.01). The MTV for water and Nutren® were significantly lower in FD (water: 1014±288 vs 1749±275 mL; t = 7.9, P = 0.001<0.01; Nutren®: 652±168 vs 1278±286 mL; t = 6.7, P = 0.001<0.01). With the volume tolerated by the controls, the percentile 10 was determined as the lower limit for tolerance. Sensitivity and specificity were 0.90, 0.95 for water and 0.95, 0.95 for Nutren® tests.
CONCLUSION: A drinking test with water or a nutritional beverage can discriminate between FD patients and healthy subjects in Mexico, with high sensitivity and specificity. These tests could be used as objective, noninvasive, and safe diagnostic approaches for FD patients.

Abstract
The irritable bowel syndrome (IBS) and other functional bowel disorders (FBDs) are common functional gastrointestinal disorders. The prevalence of IBS using Rome II criteria is generally lower than with previous criteria. The aim of this study was to determine the prevalence of IBS and other FBDs in the adult Israeli Jewish population, which has not been surveyed to date. A telephone survey was conducted on a representative sample of the study population provided by the Israel Ministry of the Interior. IBS and other FBDs were diagnosed by Rome II criteria. The study population was 981 individuals and the overall response rate was 54%. The mean age was 45.0 years and 55% were females. In all, 2.9% had IBS (females: 3.7%, males: 1.8%, P = 0.08). The rate increased to 4.1% when the Rome II diagnostic criteria were amended to include some chronic alternators who are not picked up by the original scoring system. Approximately 26% of the respondents had a functional lower gastrointestinal (GI) disorder (females: 32.1%, males: 17.7%, P < 0.0001). Prevalence rates for IBS among Israeli Jewish adults are lower than rates reported from most countries, despite the high level of stress resulting from Israel's geopolitical circumstances. Possible reasons for this low prevalence are discussed.

Abstract
OBJECTIVE Until now, the epidemiology of functional dyspepsia (FD) and its social impact on Asians have been rarely studied. The aims of this study were to determine the prevalence, social impact, and health-seeking behaviors of FD in an apparently healthy Chinese population in Taiwan. MATERIAL AND METHODS Based on the questionnaire provided by the Rome II working team, a survey was administered to a Taiwanese population receiving paid physical check-up (n = 2865). Esophagoduodenoscopy was performed in each subject to exclude organic dyspepsia. Finally, diagnoses of functional gastrointestinal disorders were obtained by means of a computer-generated algorithm. RESULTS The FD prevalences were 23.8% and 11.8% according to the Rome I and -II criteria, respectively. Nearly 60% of Rome I-defined FD subjects and 18.9% of Rome II-defined FD subjects had overlapping irritable bowel syndrome (IBS). Irrespective of any Rome definition, FD subjects had excessive physician visits, absenteeism, and sleep disturbances compared to dyspepsia-free controls (p < 0.01). Moreover, over half of the Rome II FD subjects were "consulters" showing excessive physician visits, absenteeism, and sleep disturbances than "non-consulters". The dysmotility-like subgroup (74.5%) comprised the majority of FD subjects and showed no differences to their ulcer-like counterparts in terms of major demographic data and social and health impacts. CONCLUSIONS FD is a common complaint in Taiwan and also bears an obvious social and medical burden to society. Over half of our FD subjects sought medical help, which may be due to the readily accessible medical care in Taiwan. The newly defined Rome II criteria diminish the chance of co-existence of FD and IBS. Further FD classification by the main symptoms appears of limited clinical usefulness.

Abstract
BACKGROUND & AIMS Half of Israeli Bedouin society has undergone a transition from nomadic existence to permanent towns, causing cultural and social upheaval. The aim was to compare rates of irritable bowel syndrome (IBS) and functional bowel disorders (FBDs) between Israeli Bedouins still living under rural conditions with those in permanent towns. METHODS Interviews were conducted in Arabic by trained Bedouin interviewers at 8 Bedouin clinics. The same interviewers surveyed the 2 sectors under identical sampling and interviewing conditions at the same time. FBDs were diagnosed by Rome II criteria. RESULTS One thousand seven hundred fifty-five Bedouins participated, 1018 from permanent towns and 737 from rural areas. Sixty percent were female (58.2% for rural and 62.0% for towns). The mean age was 39.1 +/- 14.1 years (39.0 +/- 14.3 years for towns, 39.2 +/- 13.9 years for rural; P = NS). The mean level of education was 4.3 +/- 5.4 years (4.6 +/- 5.6 years for towns, 3.7 +/- 5.2 years for rural; P < .0001). IBS was diagnosed in 9.4% of town and 5.8% of rural Bedouins ( P < .01). In contrast, rural Bedouins had significantly higher rates of functional abdominal bloating (7.9% vs 2.8%, P < .0001) and a marginally higher rate of functional constipation. Bedouins living in towns attributed their gastrointestinal symptoms to stress more than rural Bedouins did ( P < .05). Stress and poor global feeling of well-being were significant contributors for IBS in logistic regression models for both sectors. CONCLUSIONS Bedouins living in permanent towns have significantly higher rates of IBS than rural Bedouins. Although these findings might be associated with the stressful social upheaval that they have undergone, further study is needed to substantiate this point.

Abstract
BACKGROUND Epidemiological surveys require questionnaires to be validated in the native language of the participants. The aim of this study was to validate the Finnish translations of the Abdominal Symptom Questionnaire (ASQ), the Hospital Anxiety and Depression Scale (HAD) and the Complaint Score Questionnaire (CSQ). METHODS A random sample of adults (n = 3000) in a northern Swedish bilingual district was surveyed using a mailed ASQ offered in both SwedIsh and Finnish, and 2122 responded (239 in Finnish). A random subsample of the responders (n = 1001, 123 preferring Finish) was then surveyed once more using the ASQ, the HAD and the CSQ. The first 50 responders of the latter survey were then given the three questionnaires again within two weeks. The Finnish versions had been put through a comprehensive translation procedure RESULTS A factor analysis comparison between the responders using either language in the mailed survey gave a comparable factor construction, and this was also comparable with an earlier analysis of the Swedish version. The Finnish responses to the second survey were further evaluated by testing internal consistency reliability, convergent validity towards previously validated relevant instruments (ShortForm-36 and the Gastrointestinal Symptom Rating Scale) and the test/re-test accuracy of the three questionnaires. These were found to be reliable, as was the correlation between the ASQ and the CSQ, for relevant domains. CONCLUSION The Finnish translations of the ASQ, HAD and CSQ questionnaires all seem to be robust and usable for population-based surveys among Finnish adults.

Abstract
BACKGROUND The natural history of gastro-oesophageal reflux disease in Asian population has not been studied before. AIM To study the onset and disappearances of reflux symptoms over a 1-year period in the Chinese population. METHODS A population-based telephone survey was performed in 2002 and repeated 1 year later. The change in prevalence rate, onset and disappearance of gastro-oesophageal reflux disease, and the change in diagnoses were assessed. Factors associated with the onset and disappearance of gastro-oesophageal reflux disease were studied. RESULTS A total of 712 subjects completed the first and second survey. The annual, monthly and weekly prevalence of gastro-oesophageal reflux disease were 34.1%, 10.1% and 2.7% respectively. The onset rate (per 1000 person-year) and disappearance rate of any gastro-oesophageal reflux disease and frequent gastro-oesophageal reflux disease (> or = monthly symptoms) were 209, 40; and 395, 243 respectively. Forty-four percentage of gastro-oesophageal reflux disease subjects changed their diagnoses in 2003. By multiple logistic regression analysis, high anxiety score (OR: 1.2, 95% CI: 1.1-1.2) and higher educational level (OR: 2.7, 95% CI: 1.3-6.3) were associated with the onset of gastro-oesophageal reflux disease; while the frequency of acid regurgitation (OR: 0.35, 95% CI: 0.17-0.70) and use of antisecretory therapy (OR: 0.50, 95% CI: 0.28-0.89) were associated with the disappearance of gastro-oesophageal reflux disease. CONCLUSION The prevalence of gastro-oesophageal reflux disease is stable over 1 year. Higher anxiety score and higher educational level were associated with the onset of gastro-oesophageal reflux disease, while lower frequency of reflux symptoms and infrequent use of antisecretory therapy were associated with the disappearance of gastro-oesophageal reflux disease in a Chinese population.

Abstract
AIM To examine the prevalence of functional dyspepsia in the general population, and to evaluate the natural history/clinical course of patients with functional dyspepsia. METHODS Full-length published manuscripts during 1980-2002 were included if: (i) participants had uninvestigated or functional dyspepsia; (ii) dyspepsia was defined; (iii) for prevalence, population-based samples were evaluated; (iv) for prognosis, the total number of the inception cohort and the total number of individuals available at the end of follow-up were reported. RESULTS Twenty-two studies (1976-2002) that examined the prevalence of dyspepsia fulfilled the inclusion and exclusion criteria; 17 studies examined more than 1000 participants, but only two studies provided information sufficient to calculate the prevalence of functional dyspepsia (11.5-14.7%). The prevalence of uninvestigated dyspepsia was in the range 10-40%. When the definition of dyspepsia was restricted to participants with upper abdominal pain, irrespective of the presence of heartburn or acid regurgitation, the prevalence rate estimate was 5-12%. Thirteen studies examined the clinical course of functional dyspepsia (seven retrospective and six prospective). Sample sizes were small (n = 35-209). A follow-up ascertainment of symptoms amongst individuals in the original cohorts was obtained in 92.5-98.2% of prospective studies and in 67.7-82.2% of retrospective studies. The follow-up duration was in the range 1.5-10 years for prospective studies and 5-27 years for retrospective studies; the median follow-up duration for all studies was approximately 5 years. A variable prognosis was reported. An outcome of symptom improvement or becoming asymptomatic was reported in at least one-half of patients in 10 of the 13 studies, and in at least two-thirds of patients in six of the 13 studies. Prognostic factors were inconsistent and, in general, poorly described. CONCLUSIONS Functional dyspepsia is prevalent world-wide, but the prognosis remains poorly defined. There is a need for population-based studies to examine the prevalence and clinical course of documented functional dyspepsia.

Abstract
NCCP is a common condition in Asia. The diagnostic approach of NCCP in Asians is similar to the Western population. GERD is the most common etiology. PPI therapy is an attractive alternative to other invasive diagnostic tests for NCCP and is equally effective for the Asian population.

Abstract
BACKGROUND Population-based data on gastro-oesophageal reflux disease in Chinese are lacking. The prevalence, clinical spectrum and health care-seeking behaviour of subjects with gastro-oesophageal reflux disease were studied. METHODS Ethnic Chinese (3605) were invited to participate in a telephone survey using a validated gastro-oesophageal reflux disease questionnaire and the Hospital Anxiety and Depression Scale. RESULTS A total of 2209 subjects (58% female; mean age, 40.3 years) completed the interview. The annual, monthly and weekly prevalence rates of gastro-oesophageal reflux disease were 29.8%, 8.9% and 2.5%, respectively. Gastro-oesophageal reflux disease symptoms were associated with non-cardiac chest pain [odds ratio (OR), 2.3; 95% confidence interval (95% CI), 1.7-3.1], dyspepsia (OR, 1.9; 95% CI, 1.4-2.5), globus (OR, 1.8; 95% CI, 1.2-2.7), acid feeling in the stomach (OR, 5.8; 95% CI, 4.5-7.5) and the use of non-steroidal anti-inflammatory drugs (OR, 2.3; 95% CI, 1.5-3.6), but not with dysphagia, bronchitis, asthma, hoarseness and pneumonia. Patients with gastro-oesophageal reflux disease had a significantly higher anxiety and depression score and required more days off work when compared with subjects without. The frequency of heartburn (P = 0.032), female gender (P < 0.001), degree of depression (P = 0.004) and social morbidity (P < 0.001) were independent factors associated with health care-seeking behaviour. CONCLUSION The prevalence of gastro-oesophageal reflux disease was lower than that in Western populations, but carried a significant socio-economic burden in the studied Chinese population. The frequency of heartburn, female gender and psychosocial factors were associated with health care utilization in gastro-oesophageal reflux disease.

Abstract
BACKGROUND AND AIMS To develop a validated gastro-oesophageal disease (GERD) symptom questionnaire for the Chinese population. METHODS One hundred Chinese patients with GERD and 101 healthy Chinese controls were presented with a 20-item GERD questionnaire in the Chinese language (Chinese GERDQ). Quality of life in GERD patients was assessed by SF-36. A standard dose of proton pump inhibitors for 4 weeks was prescribed to 35 patients with newly diagnosed GERD. The Chinese GERDQ was performed before, 4 weeks and 8 weeks after treatment. Concept, content, construct, discriminant validity and reliability of the questionnaire were assessed. RESULTS Seven items were selected by logistic regression to account for most of the differences between controls and GERD patients with a good reproducibility and internal consistency. A cut-off score of equal or greater than 12 was determined to discriminate between controls and GERD patients with a sensitivity of 82% and a specificity of 84%. The Chinese GERDQ correlated negatively with five domains of the SF-36 and discriminated between GERD patients who reported symptomatic improvement during proton pump inhibitor treatment and symptoms deterioration upon withdrawal of proton pump inhibitor treatment. CONCLUSIONS The Chinese GERDQ could be used in epidemiological studies to assess the frequency and severity of GERD in patient populations and in interventional studies of GERD.
