Fit and Strong!: bolstering maintenance of physical activity among older adults with lower-extremity osteoarthritis

Susan L Hughes et al. Am J Health Behav. 2010 Nov-Dec.

Abstract

Objectives: To compare the impact of negotiated vs. mainstreamed follow-up with telephone reinforcement (TR) on maintenance of physical activity (PA) after Fit and Strong! ended.

Methods: A multisite comparative effectiveness trial with repeated measures.

Results: Single group random effects analyses showed significant improvements at 2, 6, 12, and 18 months on PA maintenance, lower-extremity (LE) pain and stiffness, LE function, sit-stand, 6-minute distance walk, and anxiety/depression. Analyses by follow-up condition showed persons in the negotiated with TR group maintained a 21% increase in caloric expenditures over baseline at 18 months, with lesser benefits seen in the negotiated-only, mainstreamed-with-TR, and mainstreamed-only groups. Significant benefits of telephone dose were also seen on LE joint stiffness, pain, and function as well as anxiety and anxiety/depression.

Conclusions: The negotiated follow-up contract that Fit and Strong! uses, bolstered by TR, is associated with enhanced long-term PA maintenance and health outcomes.
