Examination of Cancer and Aging Through Activities of Daily Living: A National Health and Aging Trends Study Analysis

Objectives: This study longitudinally examined how older adult cancer survivors perceive disability in activities of daily living over time compared to older adults who have not had cancer. Methods: This was a secondary analysis of the National Health and Aging Trends Study examining participants with a new cancer diagnosis and age-, gender-, and comorbidity-matched comparison participants without a history of cancer. Generalized linear mixed models examined time and group interaction and main effects in disability. Results: There was a significant main effect of time (F_4,771 = 12.81; p <.0001) demonstrating increasing disability levels for both groups. There were significant group differences, with higher disability in the cancer group than the comparison group (β = 0.628, SE = 0.263; t = 2.39, p = 0.017). Discussion: Although perceived disability was greater immediately following cancer diagnosis, older adult cancer survivors and comparison participants appear to have similar perceived disability over time.
