Impact of household hygiene and water source on the prevalence and transmission of Helicobacter pylori: a South Indian perspective.
In developing countries, the Helicobacter pylori (H. pylori) infection rate is high, especially in lower socioeconomic groups. The study suggests that the risk of acquisition and transmission of H. pylori among the South Indian population can be reduced by improved household hygienic practices, proper waste disposal measures as well as the regular use of boiling water for drinking purposes. The prevalence of H. pylori was 80%. Prevalence increased with an increase in age and was found to be 90% in the 70-79 year age group. Prevalence of infection among people who drank water from wells was 92% compared with 74.8% of those who drank tap water. Infection prevalence was higher in people with low clean water index (CWI) (88.2%) compared with higher CWI (33.3%). While the prevalence in subjects with lower socioeconomic status was 86.1%, in higher groups, it was 70%. Prevalence was higher in subjects living in overcrowded houses (83.7%, 76.6% and 71.3% with high, medium and low crowding index). Singapore Med J. 2007 Jun;48(6):543-9.
