title: Adherence to a Yoga Program in Older Women with Knee Osteoarthritis.
abstract: Yoga is beneficial for osteoarthritis (OA) management in older adults; however, adherence to yoga practice is unknown. The purposes of this secondary analysis were to examine: (1) yoga adherence during the intervention and follow-up periods; (2) the relationship between social cognitive theory (SCT) constructs and adherence; and (3) the impact of adherence on OA-related symptoms in 36 community-dwelling older women with knee OA. SCT was used as a framework to promote adherence to a yoga intervention program that included both group/homebased practices. Adherence to yoga was high during the intervention period but decreased over time. Although SCT was a useful framework for reducing attrition during the intervention, self-efficacy was the only construct that correlated with class attendance. Higher yoga adherence was correlated with improved symptoms, physical function, sleep quality, and quality of life. Yoga adherers were likely to be older, less educated, and had a lower body mass index than nonadherers.
