    Prospective Associations of Body Composition and Body Shape With the Risk of Developing Pancreatic Cancer in the UK Biobank Cohort by Sofia Christakoudi, Konstantinos K. Tsilidis, Marc J. Gunter, Elio Riboli

    Published 2025-03-01
    “…It is unclear, however, whether fat or fat‐free mass plays a role in these relationships, whether abdominal obesity is more important than general obesity or whether the associations with anthropometric indices and diabetes are independent of each other. Methods We used multivariable Cox proportional hazards models to examine the prospective associations of body composition (allometric fat‐mass index (AFI) and allometric lean‐mass index (ALI), based on bioelectrical impedance, uncorrelated with each other and with height), waist size (allometric waist‐to‐hip index (WHI), uncorrelated with weight and height) and diabetes with pancreatic cancer risk in UK Biobank. …”
