Résumé : | [BDSP. Notice produite par INIST-CNRS s77DR0xo. Diffusion soumise à autorisation]. Helicobacter pylori seroprevalence levels in US adults participating in the continuous National Health and Nutrition Examination Survey (1999-2000) increased with age in all racial/ethnic groups, with significantly higher age-standardized levels in Mexican Americans (64.0 %, 95 % confidence interval (CI) : 58.8,69.2) and non-Hispanic blacks (52.0 %, 95 % CI : 48.3,55.7) compared with non-Hispanic whites (21.2 %, 95 % CI : 19.1,23.2). Although seroprevalence levels remained similar to those found in National Health and Nutrition Examination Surveys from 1988 to 1991 among non-Hispanic blacks and Mexican Americans, they were significantly lower in non-Hispanic whites, especially at older ages. The factors driving the decline in H. pylori seroprevalence appear to be acting preferentially on the non-Hispanic white population. |
