Data Sheet 2_Association of ultra-processed food consumption with all-cause and cause-spec

82,221 participants from the Prostate, Lung, Colorectal and Ovarian (PLCO) Cancer Screening Trial were followed for a median of 17 years. The data, published by Ya-Dong Li in 2026, links dietary intake assessed via questionnaires to all-cause and cause-specific mortality outcomes. It includes associations between ultra-processed food consumption and mortality from circulatory, nervous system, and other diseases.

Use Cases

• Modeling all-cause mortality risk based on ultra-processed food consumption levels.
• Investigating the interaction between diet quality (HEI-2015 score) and processed food intake on health outcomes.
• Analyzing cause-specific mortality (e.g., circulatory, nervous system diseases) in relation to dietary factors.

Strengths

• 82,221 participant records provide a substantial cohort size.
• Median follow-up period of 17 years offers long-term outcome data.
• Dietary intake was assessed using validated questionnaires (BQ and DHQ).

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 and temporal bias inherent to the specific cohort trial.
