Estimating the prevalence of active Helicobacter pylori infection in a rural community with global positioning system technology-assisted sampling
Melius EJ , Davis SI , Redd JT , Lewin M , Herlihy R , Henderson A , Sobel J , Gold B , Cheek JE . Epidemiol Infect 2012 141 (3) 1-9 We investigated a possible outbreak of H. pylori in a rural Northern Plains community. In a cross-sectional survey, we randomly sampled 244 households from a geocoded emergency medical system database. We used a complex survey design and global positioning system units to locate houses and randomly selected one eligible household member to administer a questionnaire and a 13C-urea breath test for active H. pylori infection (n=166). In weighted analyses, active H. pylori infection was detected in 55.0% of the sample. Factors associated with infection on multivariate analysis included using a public drinking-water supply [odds ratio (OR) 12.2, 95% confidence interval (CI) 2.9-50.7] and current cigarette smoking (OR 4.1, 95% CI 1.7-9.6). People who lived in houses with more rooms, a possible indicator of decreased crowding in the home, were less likely to have active H. pylori infections (OR 0.7, 95% CI 0.5-0.9 for each additional room). |
