Helicobacter pylori infection in Estonian population: is it a health problem?
The role of Helicobacter pylori infection in traditionally noncommunicable diseases as chronic gastritis, peptic ulcer and gastric carcinoma became more evident during the first decade of H. pylori studies. To analyse and evaluate the prevalence of H. pylori infection in Estonia as a population health problem, the data of three randomly selected samples of Estonian population aged over 15 years were used. The infection rate assessments in two representative samples of the population (Kambja 157 persons and Kuressaare 224 persons) were based on H. pylori colonization in the gastric mucosa, and in one sample (Karksi-Nuia 1467 persons) on seroconversion of H. pylori IgG antibodies. The persons studied were divided into groups according to birth cohorts. The population studies in Estonia showed a high prevalence of H. pylori infection among Estonians: 73% in the Kuressaare sample, 78% in the Kambja sample, and 87% in the Karksi-Nuia sample. From the Kuressaare population sample 38 families with 290 persons were included in a family H. pylori infection study and 92.5% of the persons in these families were found to be H. pylori positive. H. pylori infection was frequent in persons who were born at the beginning of this century as well as in those born after World War II up to 30 years ago. It was concluded that H. pylori infection is common in Estonia, both in random persons and their families. It is probable that the infection rate of H. pylori depends to a great extent on the socioeconomic conditions of this country and that acquisition of H. pylori in Estonia starts at an early age.
