Long-term habitual physical activity and risk of mortality and long-term care insurance certification in cancer survivors: a prospective cohort study in the LIFE study, Japan

Puntos clave

• The study investigates how long-term habitual physical activity affects mortality and LTCI certification among cancer survivors.
• Conducted a 5-year retrospective analysis using a population database from 13 municipalities in Japan.
• Included cancer survivors who participated in health check-ups and had no missing exercise data.
• Analyzed outcomes of LTCI certification and all-cause mortality based on exercise categories.
• No physical activity group had a higher risk of mortality and LTCI certification than the exercise and walking group in survivors aged 65-74 years (HR: 1.72).
• In survivors aged 75 years and older, low physical activity groups also showed higher risks (HR: 1.51 for exercise or walking; HR: 1.66 for no physical activity).
• Effects of physical activity varied by cancer type, highlighting the importance of tailored interventions.
