“…We compared the H. pylori seropositivity of asymptomatic participants among the 1998, 2005, and 2011 studies7, 8, 9 and this study. The overall seropositivity of 51.0% (95% CI: 49.6‐52.4%) in this study represented a significant decrease from 66.9% (95% CI: 65.4‐68.6%) in 1998, 59.6% (95% CI: 58.5‐60.7%) in 2005, and 54.4% (95% CI: 53.5‐55.4%) in 2011 ( P < .001) (Figure 2).…”

“…Multivariable logistic regression was used for the investigation of risk factors for H. pylori seropositivity. We used the Cochran‐Armitage trend test for the comparison of H. pylori seroprevalence among the data published in 1998,7 2005,8 2011,9 and in this study. We only analyzed the results of asymptomatic participants from previous studies.…”

“…Accordingly, determination of the H. pylori prevalence of normal asymptomatic participants is crucial for the establishment of national health policies in these Eastern Asia countries. Nationwide studies of H. pylori prevalence were performed in Korea in 1998, 2005, and 2011 7, 8, 9. Although these studies obtained data from a large number of participants, they had several notable limitations, such as inconsistencies in test methods, uneven study populations, and lack of socioeconomic information.…”

BackgroundThe Korean College of Helicobacter and Upper Gastrointestinal Research has studied Helicobacter pylori (H. pylori) prevalence since 1998 and found a dynamic change in its prevalence in Korea. The aim of this study was to determine the recent H. pylori prevalence rate and compare it with that of previous studies according to socioeconomic variables.MethodsWe planned to enroll 4920 asymptomatic Korean adults from 21 centers according to the population distribution of seven geographic areas (Seoul, Gyeonggi, Gangwon, Chungcheong, Kyungsang, Cholla, and Jeju). We centrally collected serum and tested H. pylori serum IgG using a chemiluminescent enzyme immunoassay.ResultsWe analyzed 4917 samples (4917/4920 = 99.9%) from January 2015 to December 2016. After excluding equivocal serologic results, the H. pylori seropositivity rate was 51.0% (2414/4734). We verified a decrease in H. pylori seroprevalence compared with previous studies performed in 1998, 2005, and 2011 (P < .0001). The H. pylori seroprevalence rate differed by area: Cholla (59.5%), Chungcheong (59.2%), Kyungsang (55.1%), Jeju (54.4%), Gangwon (49.1%), Seoul (47.4%), and Gyeonggi (44.6%). The rate was higher in those older than 40 years (38.1% in those aged 30‐39 years and 57.7% in those aged 40‐49 years) and was lower in city residents than in noncity residents at all ages.Conclusions Helicobacter pylori seroprevalence in Korea is decreasing and may vary according to population characteristics. This trend should be considered to inform H. pylori‐related policies.

Global Incidence and Mortality of Gastric Cancer, 1980-2018

IMPORTANCE Gastric cancer is one of the most common cancers, with a high mortality-to-incidence ratio. It is uncertain whether developed nations may encounter an increasing burden of gastric cancer in young adults, as occurs for other cancers.OBJECTIVES To evaluate the incidence and mortality of gastric cancer and compare the global incidence trends between younger (<40 years) and older (Ն40 years) populations. DESIGN, SETTING, AND PARTICIPANTSThis population-based cohort study analyzed data from global and national cancer registries, including data from 1980 to 2018, with at least 15 calendar years of incidence and mortality data. Data on age-standardized incidence and mortality rates of gastric cancer among 48 countries were retrieved from the Surveillance, Epidemiology, and End Results Program, the National Cancer Institute, the Nordic Cancer Registries, and the World Health Organization Mortality Database. The 10-year incidence trend of gastric cancer was assessed by age and sex. The 2018 GLOBOCAN database was used for reporting the global incidence and mortality of gastric cancer, the most recent data available at the time of analysis. Analyses were performed

Seroprevalence of Helicobacter pylori in South Korea

Abstract: The seroprevalence of H. pylori in asymptomatic health check-up adult subjects in 2005 decreased to 59.6% from 66.9% in 1998, probably as a result of the improvement of socioeconomic status and hygiene.
