Frequency of Physical Activity Done with a Companion: Changes Over Seven Years in Adults Aged 60+ Living in an Australian Capital City.

Objectives: This study examined how often adults 60+ years were physically active with a partner, close family, friends, and neighbors, over 7 years. Methods: Data from 2062 adults living in an Australian capital city were collected using a mail survey at four time points and analyzed using multinomial logistic regression. Results: A partner was the most frequent companion at all time points. From baseline to 7 years, the greatest decline was activity with family 1-4x/month (.79 [.64-.98]) and ≥5x/month (.54 [.36-.80]). There were also decreases in activity 1-4x/month with a partner (OR = .75, [.62-.92]), friends (.55 [.44-.68]), and neighbors (.79 [.64-.98]). Physical activity with friends or neighbors ≥5x/month did not decline. Discussion: Findings extend understanding of physical activity and activity companions among older adults. More research is needed to understand factors contributing to changes in activity done with companions.
