The objective of this analysis was to investigate the relationship between pain and quality of life and physical activity as a mediator in the relationship between pain and quality of life. This study utilised a combination of questionnaire data from 503 community-living people aged 70-years and over concerning quality of life, pain, and physical activity. Participants with higher levels of pain intensity experienced lower quality of life and engaged in lessphysical activity (P < 0.05). Physical activity was a mediator in the relationship between pain and quality of life(6.5 %). This study confirms an association between pain and quality of life and highlights physical activ-ity as an essential component of this relationship; further research is needed to understand the mechanism of this relationship.
