Changes in physical activity since cancer diagnosis and associations with health-related quality of life: a study of adults living with advanced cancer.

Abstract

Purpose: Physical activity (PA) is associated with better quality of life for cancer survivors; however, less is known about this association among individuals with advanced cancer. This study assesses whether changes in PA following an advanced cancer diagnosis are associated with health-related quality of life (HRQoL) outcomes.

Methods: Data were collected from 247 participants in a survey of adults with advanced cancer who visited the University of Wisconsin Carbone Cancer Center (January 2021-2023). PA since cancer diagnosis was assessed using a validated, self-reported tool. HRQoL was assessed using the Functional Assessment of Cancer Therapy - General and Patient-Reported Outcomes Measurement Information System measures of physical function, fatigue, and pain interference. We used generalized linear models to assess relationships between PA and HRQoL.

Results: Most adults with advanced cancer were insufficiently active (53%), and reported a lot less activity (41%) after diagnosis, followed by a little less activity (33%), and the same/more activity (26%). Compared to the other activity groups, those who reported a lot less activity had the worst HRQoL scores, including lower HRQoL (x̄ = 70.3 vs. x̄ = 82.6, 90.7) and physical function (x̄ = 40.3 vs. x̄ = 47.3, 52.5), and higher fatigue (x̄ = 59.3 vs. x̄ = 51.4, 42.3) and pain interference (x̄ = 55.5 vs. x̄ = 48.8, 45.6).

Conclusions: Adults with advanced cancer who report PA reductions have worse HRQoL, higher pain and fatigue, and lower physical function than those engaging in the same/more PA since their diagnosis. Future interventions focused on improving HRQoL among adults with advanced cancer should incorporate light-intensity PA to reduce declines following diagnosis.
