SURVPOOL: A Consortium on Risk Factors and Cancer Survival

The aim of the SURVPOOL project is to investigate the potential influence of lifetime exposure to modifiable risk factors, such as overweight and obesity, on the occurrence of cancer and death due to cancer. Here, we describe succinctly the methodology used to

• define individual-specific indicators of lifetime exposure to overweight and obesity from repeated BMI measurements; and
• assess the effect of these indicators on a time-to-event outcome (occurrence of cancer or death due to cancer).
