Gastric Cancer Risk According to BMI Change in a Korean Cohort

Su Youn Nam's dataset contains results from a nationwide cohort study examining the association between body mass index (BMI) change trajectories and gastric cancer risk. The study followed 2,800,588 cancer-free Korean adults aged 40 and over from 2009-2013 through 2017, identifying 14,662 incident gastric cancers. It evaluates effect modification by sex, age, smoking, and menopausal status using Cox proportional hazards models.

Use Cases

• Analyze gastric cancer risk associations based on BMI change trajectories.
• Investigate effect modification of BMI-cancer links based on sex, age, and smoking status.
• Model hazard ratios for gastric cancer using categorized BMI and demographic subgroups.

Strengths

• Dataset is based on a large cohort of 2,800,588 participants.
• Analysis includes 14,662 incident gastric cancer cases for robust statistical power.
• Results are stratified by key demographic factors including sex, age, and smoking status.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the Korean cohort.
