Cross-sectional survey of 1400 adults conducted from August to October 2025
Used structured 45-item questionnaire covering four knowledge domains: risk factors, symptoms, prevention, management
Analyses included independent t-tests, one-way ANOVA, chi-squared tests, and multivariable linear regression
Mean total knowledge score was 18.94 ± 7.34/37 (51.2%) with domain scores: risk factors 4.95 ± 2.04/11 (45.0%), symptoms 4.54 ± 2.87/10 (45.4%), prevention 4.91 ± 2.09/10 (49.1%), management 2.99 ± 1.95/6 (49.8%)
Knowledge was significantly associated with occupation (p < 0.001) and educational attainment (β = 0.30, p < 0.001) as well as family history of gastric cancer (p = 0.003)
Only 34% correctly identified Helicobacter pylori as a risk factor for gastric cancer.
