High-risk populations include: (1) Gastric cancer high-risk population: Age >=45 years, and meeting any of the following criteria: 1) Residing in a high-incidence area of gastric cancer (defined at the county-level administrative unit, with age-standardized incidence rate >20/100,000 using the 2000 Chinese population structure as standard); 2) Having a family history of gastric cancer among first-degree relatives (parents, children, and siblings); 3) Positive result from any of the following: urea breath test, serum *Helicobacter pylori* (Hp) antibody, or stool Hp antigen test; 4) Having unhealthy lifestyle and dietary habits such as smoking, heavy drinking, high-salt diet, and preserved foods; 5) Having chronic atrophic gastritis, gastric ulcer, gastric polyps, remnant stomach after surgery, hypertrophic gastritis, pernicious anemia, or other such diseases.
