Sedentary behavior as a modifiable risk factor for anemia and mortality in cancer survivors aged 55 years and older

This study reveals that from 1990 to 2021, global cancer mortality related to low physical activity has declined. Furthermore, the prolonged sedentary time in cancer patients is significantly associated with anemia, and their synergistic effect increases mortality risk. Sedentary behavior particularly increases the mortality risk of gynecological cancers. These findings suggest that clinical strategies should prioritize interventions tailored to different tumor types, particularly those managing sedentary behavior and anemia.
