摘要：). Increasing CRF was inversely associated with incidence and mortality of respiratory/thoracic cancers, HRs 0.78 (95%CI:0.67-0.90) and 0.73 (95%CI:0.63-0.84) respectively; and all cancer-cause incidence 0.92 (95%CI:0.86-0.98) and mortality 0.85 (95%CI:0.79-0.91). Physical activity (PA) was not associated with most outcomes. We found no evidence of interactions between CRF or PA and BMI on cancer risk. This evidence suggests that midlife CRF is associated with lowered risk of cancer incidence and mortality with no evidence of cancer risk modification by BMI.
