Korean Adult BMI Trajectories and Gastric Cancer Risk, 2009-2017

Su Youn Nam's dataset contains baseline characteristics for a nationwide cohort study examining the association between body mass index (BMI) 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.

Use Cases

• Analyze the association between persistent obesity and gastric cancer risk based on BMI trajectory groups.
• Investigate effect modification by demographic factors like sex and age mentioned in the study description.
• Model hazard ratios for gastric cancer based on BMI change categories, such as gain from normal to overweight.

Strengths

• Based on a large cohort of 2,800,588 participants.
• Includes longitudinal data with follow-up from 2009/2013 to 2017.
• Analyzes 25 distinct BMI trajectory groups.

Limitations

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