What is Changes in prevalence of Helicobacter pylori in Japan from 2008 to 2018: a repeated cross-sectional study about?
## Objectives To understand the recent prevalence and time trends of __Helicobacter pylori__ infection rates in the Japanese population. ## Design Repeated cross-sectional study. ## Participants A total of 22 120 workers (age: 35–65 years) from one Japanese company, who underwent serum __H. pylori__ antibody tests in a health check-up between 2008 and 2018. ## Measures __H. pylori__ infection rates among participants aged 35 years from 2008 to 2018, and participants aged 35, 40, 45, and 50–65 years in 2018, based on the results of serum antibody tests, were analysed. In the 2018 analysis, in addition to the antibody test results, all participants who had undergone eradication treatment for __H. pylori__ were considered as infected. Trends were examined using joinpoint analysis. ## Results __H. pylori__ was detected in 1100 of 7586 male and 190 of 1739 female participants aged 35 years. Annual infection rates among those aged 35 years showed linear downward trends as follows: men, 17.5% in 2008 to 10.1% in 2018 (slope: −0.66); women, 12.3% in 2008 to 9.2% in 2018 (slope: −0.51) without joinpoints. In the 2018 analysis, 2432 of 9580 men and 431 of 1854 women were __H. pylori__ positi
