title: [Distribution of Helicobacter pylori infection in the adult population of Croatia].
abstract: The study of the distribution of Helicobacter pylori infection was carried out among the population of Croatia aged between 20 and 70 years, in three areas of Croatia (central, northern, southern). For the detection of seroprevalence of this infection the ELISA test for IgG antibodies was used on a random sample of 3,082 serum samples. The testing showed an average rate of seroprevalence in Croatia of 60.4% (95% CI 58.7-62.1%). Higher infection rates were observed in older population of Croatia. These rates ranged from 51.6% in the third decade of life, to almost 70% in the sixth decade. In male subjects the average rate was 58.9% and in female subjects it was 65.9%. The difference was not statistically significant. The results of this study showed that distribution of this infection was not consistent in all the studied areas of Croatia. While the Helicobacter pylori infection prevalence was almost identical in the central area and in the northern counties of Croatia, 58.4% and 59.5% respectively, it showed statistically significant difference in the south, being 71.3% (chi(2) = 25.884, P < 0.001). An inconsistent distribution of this infection in Croatia was indicated also by standardized infection rates, which were 59 in the central area, 61 in the northern and 71 in the southern areas.
