Abstract
Purpose: This study investigated the associations between physical activities (PAs) and the health-related quality of life (HRQOL) and perceived health status (PHS) of cancer survivors. We further examined the interaction effects of PAs and covariates on HRQOL and PHS.

Methods: Data sets were obtained from the 2014-2018 Korea National Health and Nutrition Examination Survey. The subjects were 1,349 cancer survivors aged over 18 years old. Data were analyzed using R 4.0.3 and SPSS 18.0. Logistic regression analysis was conducted considering only the main terms, or including additional interaction terms between PAs and covariates.

Results: Moderate and high PAs showed significantly improved HRQOL related to self-care domain, euro quality of life-5 dimension index, and PHS. Interaction analysis revealed that high PAs resulted in improved HRQOL associated with self-care and pain/discomfort in cancer survivors having depression. Moreover, for low- and middle-income levels, higher PAs served to improve HRQOL associated with depression/anxiety. In contrast, higher PAs rather reduced HRQOL for the high-income group.

Conclusions: To improve HRQOL, we recommend PAs higher than the moderate level for cancer survivors. In case of cancer survivors having depression or belonging to the high-income group, it is necessary to manage individual PAs considering the interaction effects.
