Lifestyle Risk Score for Chronic Atrophic Gastritis, Validated on 21,008 Chinese Adults

A dataset from a population-based case-control study of 21,008 Chinese adults aged 40–70 years, used to develop and validate a lifestyle-derived risk score for chronic atrophic gastritis. The study was conducted by Runze Guo using data from the Upper Gastrointestinal Cancer Screening Program in Gansu Province, China. The dataset was last updated on April 21, 2026.

Use Cases

• Validate the association between modifiable lifestyle factors and chronic atrophic gastritis risk based on the seven-factor score described.
• Benchmark predictive performance of clinical risk scores using the reported ROC curve area of 0.597.
• Assess the net clinical benefit of a screening tool using the decision curve analysis results mentioned in the description.
• Study the prevalence of chronic atrophic gastritis in a Chinese screening population, reported as 44.5%.

Strengths

• Dataset is based on a large sample of 21,008 participants.
• Risk score was validated with specific performance metrics, including an adjusted odds ratio of 1.506 per point increase.
• Clear methodology described for score development using multivariate logistic regression and calibration analysis.

Limitations

• Row count and column-level documentation are unknown, limiting suitability assessment.
• Data is specific to a Chinese provincial screening program, which may limit generalizability to other populations.
• The dataset file is a 27.3 KB DOCX document, suggesting limited raw data scope.
