[show abstract] [hide abstract]
ABSTRACT: The prevalence of irritable bowel syndrome (IBS) varies from 4% to 20% in different Asian nations. Prevalence of IBS in native North Indian community is not known. Between November 2008 to December 2009, we estimated the prevalence of IBS in a rural community of Ballabgarh block, located in Haryana state. A structured questionnaire based on Rome III module was used to collect symptoms related to IBS from all the participants in a door to door survey. A Rome III criterion was used for diagnosis of IBS. IBS was further classified based on predominance of symptoms as constipation predominant, diarrhea predominant, mixed and unspecified based on Rome III module. There were 4,767 participants (mean age 34.6 ± 10.8, males 50%). Overall, 555 (11.6%; 95% CI, 10.7-12.5) had constipation, 542 (11.4%; 95% CI, 10.5-12.3) diarrhea and 823 (17.3%; 95% CI, 16.2-18.4) abdominal pain. The overall prevalence of IBS was 4% (95% CI, 3.5-4.6). The prevalence of constipation predominant IBS was 0.3% (95% CI, 0.16-0.49), diarrhea predominant IBS 1.5% (95% CI, 1.18-1.90), mixed IBS 1.7% (95% CI, 1.35-2.11) and unsubtyped IBS 0.5% (95% CI, 0.32-0.75). The prevalence of IBS was significantly higher in females compared with males (4.8% vs 3.2%, P = 0.008). However, there was no significant difference between males and females in the prevalence of different subtypes of IBS. The prevalence increased with age. The prevalence of IBS in a North Indian community is 4%. IBS poses a significant burden on the rural adults.Journal of neurogastroenterology and motility 01/2011; 17(1):82-7. -
Article: Prevalence of celiac disease in the northern part of India: a community based study.
[show abstract] [hide abstract]
ABSTRACT: While celiac disease is estimated to affect about 1% of the world's population, it is thought to be uncommon not only in India but in Asia also. There is a lack of studies on the prevalence of celiac disease from Asian nations. The aim of the present study was to estimate the prevalence of celiac disease in the community. In a cross sectional study, we estimated the prevalence of celiac disease in urban and rural populations in the National Capital Region, Delhi, India. A structured questionnaire was administered, by door-to-door visits, to all participants to collect socio-demographic data and to screen for features of celiac disease, namely chronic or recurrent diarrhea and, anemia. In children, additional features, namely short stature (linear height below 5th percentile for age) and failure to thrive/gain weight were also used. All respondents who were screen positive (any one of above) and 10% of screen negative individuals were called for serological testing, which is anti-tissue transglutaminase antibody. All serologically positive respondents were invited to undergo further evaluation including endoscopic biopsy. Celiac disease was diagnosed on the basis of a positive serology, the presence of villous atrophy and/or response to gluten free diet. Among 12,573 contacted, 10,488 (83.4%) (50.6% male) agreed to participate. Based on screening, 5622 (53.6%) participants were screen positive. Of all those screen positive, 2167 (38.5%) agreed for serological testing; additionally 712 (14%) negatives were also tested. The overall sero-prevalence of celiac disease was 1.44% (95% confidence interval [CI] 1.22 1.69) and the overall prevalence of celiac disease was 1.04% (95% CI 0.85 1.25). The prevalence of celiac disease in this north Indian community is 1 in 96. Celiac disease is more common than is recognized in India.Journal of Gastroenterology and Hepatology 12/2010; 26(5):894-900. · 2.87 Impact Factor
