An Outsourced Health-enhancing Physical Activity Program for People with Rheumatoid Arthritis: Study of the Maintenance Phase.

Objective: To describe changes of health-enhancing physical activity (HEPA), health perception, and functioning during the second year of a 2-year support program, determine aspects of adherence and response, and describe perceptions of the program.
Methods: Out of 220 individuals with rheumatoid arthritis (RA), 177 participated in the followup. Group support, strength training, and moderate-intensity aerobic activity were encouraged. Data collection included HEPA, perceived health, functioning, and perceptions of the program. Participants with unchanged/improved general health perception and at least 2 of aerobic capacity, grip strength, or timed standing were considered responders.
Results: Current and maintained HEPA decreased from 82% to 75% (p = 0.0141) and from 41% to 27% (p < 0.0001) during the second year. Minor declines in quality of life and activity limitation occurred (p = 0.0395 and 0.0038, respectively), while outcome expectations for benefits of physical activity increased (p = 0.0010 and 0.0186) and waist circumference tapered off (p = 0.0070). Strength training was performed on average 41 and 35 times among responders (n = 54) and nonresponders (n = 105), respectively (p = 0.2708); HEPA 194 and 171 days, respectively (p = 0.0828); and support group meetings 12 and 10 times, respectively (p = 0.0943). Strength training, aerobic activity, and short text message reminders were perceived as most valuable; step registration and the self-monitoring walk tests were less appreciated.
Conclusion: About one-fourth of the originally sedentary individuals with RA sustained their new HEPA behaviors after 2 years and most improvements of health and functioning were sustained. Structured use of behavior change techniques and a second year to support maintenance with a reduced program might help patients with RA to sustain HEPA behavior.
