Objective:To explore the association between self-perception of aging and physical activity in elderly colorectal cancer patients, so as to provide reference for clinical physical activity intervention programs.Methods:From July 2022 to March 2023, convenience sampling was used to select 234 colorectal cancer patients in three Class Ⅲ Grade A hospitals in Jinan, Shandong Province as participants. Cross-sectional survey was conducted using the General Information Questionnaire, Brief Ageing Perceptions Questionnaire (B-APQ), and Physical Activity Measurement Scale for Cancer Patients. Multiple linear regression was used to explore the influencing factors of physical activity in elderly patients with colorectal cancer.Results:A total of 234 questionnaires were distributed, and 221 valid questionnaires were collected, with a valid response rate of 94.44% (221/234). Among 221 elderly patients with colorectal cancer, the score of B-APQ was (46.28±11.89), and physical activity was 52.50 (30.00, 77.75) hours per week. Multiple linear regression showed that self-perception of aging, regular physical activity before illness, self-evaluation of physical health, and disease stage were the influencing factors of physical activity in elderly colorectal cancer patients ( P<0.05) . Conclusions:Elderly patients with colorectal cancer tend to have a negative perception of aging and low levels of physical activity. Medical and nursing staff should attach importance to the assessment and intervention of patients' self-perception of aging to improve their physical activity.
