[Possibilities of epidemiologic studies within the scope of school entrance examinations exemplified by Ulm Helicobacter pylori studies].
This paper illustrates the possibilities and the evidential value of epidemiologic studies in combination with the pre-school screening examinations, which in Germany are mandatory for all children who are to attend school for the first time. Aspects of study design and study conduct are discussed primarily. We used two studies conducted in the city of Ulm in 1996 and in 1997. The aim of these studies was to investigate the prevalence, determinants and effects of Helicobacter pylori infection among pre-school children and their parents. Study subjects were all pre-school children in Ulm, a city in the South of Germany, who were screened for school fitness by physicians of the Public Health Service in 1996 and 1997, respectively. Infection status was determined by 13C-urea breath test. In addition, the parents of the children were asked to fill out a standardized questionnaire. In the 1997 study, the infection status of the accompanying parents was also evaluated by 13C-urea breath test. We present some selected results from the study of 1996. In total 945 out of the 1201 eligible pre-school children participated in the study (response rate = 79%). Overall, 127 children (13.4%) were infected with Helicobacter pylori. The prevalence varied between 6.1% in the children with German nationality to 44.8% in children with Turkish nationality and 24.8% in children with other nationality. In addition, we identified further determinants and investigated effects of the infection. The results of these studies demonstrate that epidemiologic studies combined with the mandatory screening examinations in pre-school children may be an important and feasible way to gain knowledge. The participation of the Public Health Service is of special advantage and allows to collect health related data in a efficient way.
