AIM: To survey irritable bowel syndrome (IBS) using Rome III criteria among Malays from the north-eastern region of Peninsular Malaysia.METHODS: A previously validated Malay language Rome III IBS diagnostic questionnaire was used in the current study. A prospective sample of 232 Malay subjects (80% power) was initially screened. Using a stratified random sampling strategy, a total of 221 Malay subjects (112 subjects in a “full time job” and 109 subjects in “no full time job”) were recruited. Subjects were visitors (friends and relatives) within the hospital compound and were representative of the local community. Red flags and psychosocial alarm symptoms were also assessed in the current study using previously translated and validated questionnaires. Subjects with IBS were sub-typed into constipation-predominant, diarrhea-predominant, mixed type and un-subtyped. Univariable and multivariable analyses were used to test for association between socioeconomic factors and presence of red flags and psychosocial alarm features among the Malays with IBS.RESULTS: IBS was present in 10.9% (24/221), red flags in 22.2% (49/221) and psychosocial alarm features in 9.0% (20/221). Red flags were more commonly reported in subjects with IBS (83.3%) than psychosocial alarm features (20.8%, P < 0.001). Subjects with IBS were older (mean age 41.4 years vs 36.9 years, P = 0.08), but no difference in gender was noted (P = 0.4). Using univariable analysis, IBS was significantly associated with a tertiary education, high individual income above RM1000, married status, ex-smoker and the presence of red flags (all P < 0.05). In multiple logistic regression analysis, only the presence of red flags was significantly associated with IBS (odds ratio: 0.02, 95%CI: 0.004-0.1, P < 0.001). The commonest IBS sub-type was mixed type (58.3%), followed by constipation-predominant (20.8%), diarrhea-predominant (16.7%) and un-subtyped (4.2%). Four of 13 Malay females (30.8%) with IBS also had menstrual pain. Most subjects with IBS had at least one red flag (70.8%), 12.5% had two red flags and 16.7% with no red flags. The commonest red flag was a bowel habit change in subjects > 50 years old and this was reported by 16.7% of subjects with IBS.CONCLUSION: Using the Rome III criteria, IBS was common among ethnic Malays from the north-eastern region of Peninsular Malaysia. 相似文献

AIM: To describe the bowel habits and the prevalence of irritable bowel syndrome(IBS) and to investigate the influence of health behavior and social factors on IBS prevalence in university students. METHODS: This cross-sectional study was conducted at five major universities in Greater Beirut and its suburbs, between February and June 2014. Using a convenience sample, a total of 813 students aged 18 years old and above participated in this study. Participants were asked to complete a comprehensive anonymous questionnaire which detailed characteristics on socio-demographic, health-related, and lifestyle factors, as well as IBS. The ROME Ⅲ criteria were used as a tool to ascertain IBS. A χ2 test was used to determine differences between categorical variables; stepwise logistic regression was used to measure the association between IBS and its risk factors.RESULTS: An overall prevalence of IBS of 20% was recorded among university students. The bivariate analysis showed that females were significantly more likely to report having IBS than males(29.1% vs 18.2%, P < 0.01). Those living at the school dormitory or in a private residence(39.5%) were more likely to have IBS than those living with their families(16.3%)(P < 0.01). The multivariate analysis showed that those who had a relatively high family income level(US$ > 2000) were almost 6 times more likely to report havingIBS than their counterparts.CONCLUSION: This is the first study to describe the nature of IBS among young adults in Lebanon. The prevalence of IBS among university students in our sample was higher than that reported in the West. 相似文献

AIM: To investigate the latent structure of an irritable bowel syndrome(IBS) symptom severity scale in a population of healthy adults.METHODS: The Birmingham IBS symptom questionnaire which consists of three symptom specific scales(diarrhea,constipation,pain) was evaluated by meansof structural equation modeling.We compared the original 3-factor solution to a general factor model and a bifactor solution in a large internet sample of college students(n = 875).Statistical comparisons of competing models were conducted by means of χ2 difference tests.Regarding the evaluation of model fit,we examined the comparative fit index(CFI) and the Root Mean Square Error of Approximation(RMSEA).RESULTS: Results clearly favored a bifactor model of IBS symptom severity(CFI = 0.99,RMSEA = 0.05) which consisted of a strong general IBS somatization factor and three symptom specific factors(diarrhea,constipation,pain) based on the subscales of the Birmingham IBS symptom questionnaire.The fit indices of the competing one factor model(CFI = 0.85,RMSEA = 0.17) and three factor model(CFI = 0.97,RMSEA = 0.08) were clearly inferior.χ2 difference tests showed that the differences between the models were indeed significant in favor of the bifactor model(P 0.001).Correlations of the four latent factors with measures of pain sensitivity,somatoform dissociation,fatigue severity,and demographic variables support the validity of our bifactor model of IBS specific symptom severity.CONCLUSION: The findings suggest that IBS symptom severity might best be understood as a continuous and multidimensional construct which can be reliably and validly assessed with the B-IBS. 相似文献

Irritable bowel syndrome (IBS) is a highly prevalent functional disorder that reduces patients’ quality of life. It is a chronic disorder characterized by abdominal pain or discomfort associated with disordered defecation in the absence of identifiable structural or biochemical abnormalities. IBS imposes a significant economic burden to the healthcare system. Alteration in neurohumoral mechanisms and psychological factors, bacterial overgrowth, genetic factors, gut motility, visceral hypersensitivity, and immune system factors are currently believed to influence the pathogenesis of IBS. It is possible that there is an interaction of one or more of these etiologic factors leading to heterogeneous symptoms of IBS. IBS treatment is predicated upon the patient’s most bothersome symptoms. Despite the wide range of medications and the high prevalence of the disease, to date no completely effective remedy is available. This article reviews the literature from January 2008 to July 2013 on the subject of IBS peripherally acting pharmacological treatment. Drugs are categorized according to their administration for IBS-C, IBS-D or abdominal pain predominant IBS. 相似文献

Epidemiology of irritable bowel syndrome in Chinese 总被引:12,自引:0,他引:12
Irritable bowel syndrome (IBS) is common in Caucasians and Japanese, but its epidemiology has not been studied in urbanized Chinese populations. Our aim was to compare diagnostic criteria and study the epidemiology of IBS in Hong Kong Chinese. In all, 964 subjects from public housing and 334 subjects from private housing were recruited for face-to-face interviews in Shatin, Hong Kong. A structured questionnaire was used to measure the prevalence of IBS according to the Manning, Rome I, and Rome II criteria. The SF-36 scale was used to measure quality of life (QOL) in subjects with IBS and in normal controls. The results were compared by the analysis of covariance (ANCOVA). Relevant medical consultations and absence from work were recorded. There was fair agreement between the Manning and Rome II criteria ( = 0.23; P < 0.001), but good agreement between the Rome I and Rome II criteria ( = 0.5; P < 0.001). The prevalence of IBS, based on the Rome II criteria, was 3.6% (95% CI = 2.0–5.2) in men and 3.8% (95% CI = 2.5–5.2) in women. Men with IBS had significantly lower vitality scores on the SF-36 scale than the controls (P < 0.05 by ANCOVA), and women with IBS had significantly lower mental health scores than controls (P < 0.05 by ANCOVA). In conclusion, IBS is quite prevalent in Hong Kong Chinese, and the QOL of subjects with IBS was significantly affected. 相似文献

AIM To estimate annual direct and indirect costs for patients diagnosed with irritable bowel syndrome(IBS) and subtypes.METHODS Patients completed a standardized questionnaire concerning usage of healthcare resources, travel costs, meals, and productivity loss of patients when seeking treatment for IBS. Total annual costs per patient were calculated as the sum of direct(including medical and nonmedical) and indirect costs. Total annual costs per patient among various IBS subtypes were compared. Analysis of variance and bootstrapped independent sample t-tests were performed to determine differences between groups after controlling for IBS subtypes.RESULTS A total of 105 IBS patients(64.80% female), mean age of 57.12 years ± 10.31 years), mean disease duration of 4.31 years ± 5.40 years, were included. Total annual costs per patient were estimated as CNy18262.84(USD2933.08). Inpatient and outpatient healthcare use were major cost drivers, accounting for 46.41%and 23.36% of total annual costs, respectively. Productivity loss accounted for 25.32% of total annual costs. The proportions of direct and indirect costs were similarto published studies in other countries. Nationally, the total costs of managing IBS would amount to CNy123.83 billion(USD1.99 billion). Among the IBS subtypes, total annual costs per patient of IBS-M was highest at CNy18891.18(USD3034). Furthermore, there was significant difference in productivity loss among IBS subtypes(P = 0.031).CONCLUSION IBS imposes a huge economic burden on patients and healthcare systems, which could account for 3.3% of the total healthcare budget for the entire Chinese nation. More than two-thirds of total annual costs of IBS consist of inpatient and outpatient healthcare use. Among the subtypes, IBS-M patients appear to have the greatest economic burden but require further confirmation. 相似文献

McFarland LV 《World journal of gastroenterology : WJG》2008,14(17):2625-2629
Irritable bowel syndrome (IBS) and inflammatory bowel disease (IBD) are two of the leading causes of chronic intestinal conditions in the world. This issue of World Journal of Gastroenterology ( WJG) presents a series of papers from world experts who discuss the current knowledge and opinions on these important conditions. Although great strides have been made in the diagnosis, treatment and pathology of IBS and IBD; much has yet to be explained. The etiologies and risk factors of these multifactorial conditions remain elusive. Specific diagnostic biomarkers need to be developed and safer treatments developed. The burden of IBS and IBD on the healthcare system is felt with repeated medical care visits and high costs. IBS and IBD patients can account for 30%-50% of office visits at gastroenterology services/clinics. Over one million people have IBD in the United States, with 30000 new cases being diagnosed every year. One-quarter million people in the UK are afflicted with IBD. The cost of medical care in the United States for IBD is estimated to be $1.8 billion/year. 相似文献

Irritable bowel syndrome (IBS) is a complex clinical process with multiple pathophysiologic mechanisms. There has recently been a shift in the treatment of patients with severe IBS symptoms to disease-modifying therapies as opposed to symptomatic treatment. Because pathophysiologic differences exist between men and women, so does the efficacy of treatment options. These differences could further explain gender-related differences in disease prevalence and treatment response. A brief discussion of the definition, epidemiology, and diagnostic criteria of IBS is followed by a comprehensive review of the current treatment choices and potential future therapeutic options of IBS in women. 相似文献

Post-infectious irritable bowel syndrome (PI-IBS) is a common disorder wherein symptoms of IBS begin after an episode of acute gastroenteritis. Published studies have reported incidence of PI-IBS to range between 5% and 32%. The mechanisms underlying the development of PI-IBS are not fully understood, but are believed to include persistent sub-clinical inflammation, changes in intestinal permeability and alteration of gut flora. Individual studies have suggested that risk factors for PI-IBS include patients' demographics, psychological disorders and the severity of enteric illness. However, PI-IBS remains a diagnosis of exclusion with no specific disease markers and, to date, no definitive therapy exists. The prognosis of PI- IBS appears favorable with spontaneous and gradual resolution of symptoms in most patients. 相似文献

BACKGROUND AND AIMS: As part of a public education program, the Hong Kong Society of Gastrointestinal Motility studied the prevalence of irritable bowel syndrome (IBS) in the community, which was based on the recently published Rome II criteria. The distribution of diarrhea or constipation-predominant IBS subtypes, the prevalence of bowel symptoms and the predictors of health-care seeking were also studied. METHODS: Among 1797 randomly selected respondents, 1000 successful telephone interviews (56%) were conducted from August 2000 to December 2000, using a validated questionnaire in Chinese that looked into demographic data and various bowel symptoms during the past year. RESULTS: The 12-month prevalence of IBS as defined by the Rome II criteria in Hong Kong was 6.6%. The female to male ratio was 1.3:1, but this ratio was the same in the control group. The distribution of IBS patients into diarrhea predominant, constipation predominant, and non-specific subtypes was 27, 17 and 56%, respectively. The predominant symptom in the IBS group was pain (54.5%), followed by urgency (15%), abdominal distension (15%) and diarrhea (11%). Forty-seven percent of IBS patients sought medical attention and only 21% of them knew that they had IBS. Moderate to severe pain severity (odds ratio 3.7, 95% CI 1.02-13) and mucus in stool (odds ratio 3.57, 95% CI 1.18-10.7) were associated with health-care seeking in univariate analysis. The prevalence of bowel symptoms such as urgency, straining, feeling of incomplete defecation, mucus in stool and abdominal distension ranged from 11 to 41%. CONCLUSION: The prevalence of IBS in Hong Kong was 6.6%, and the female to male ratio was similar to the control group. The majority was of non-specific IBS subtype. Gross underdiagnosis (21%) by Western practitioners was noted. 相似文献
