摘要:State infrastructure for aging services, such as programs in county senior centers, can help promote prevention of chronic disease and reach large numbers of older adults. The objective of our study was to assess how well such infrastructure can support prevention efforts. The University of Pittsburgh CDC Prevention Research Center partnered with the Pennsylvania Department of Aging APPRISE program to deliver the 10 Keys to Healthy Aging program. APPRISE is a Medicare counseling program offered at senior centers; the 10 Keys is a series of behavior-activation workshops for people aged 50 or older that cover recommendations of the US Preventive Services Task Force and other evidence-based recommendations for health promotion. We assessed implementation, increases in prevention knowledge, and maintenance of prevention behavior. From 2013 through 2016, 1,534 adults at 83 sites participated in the program; 1,044 (68.1%) completed at least 8 of 10 Keys workshops. A total of 736 adults (mean [standard deviation] age, 74.9 [8.3] y) voluntarily completed a 14-item pretest and posttest of prevention knowledge; respondents' knowledge score increased from 61.5% to 78.5% correct (P < .001). In a subsample (n = 339) reporting on their own prevention behaviors at baseline, quiz scores and prevention behaviors were correlated (r = 0.30, P < .001). In monthly telephone follow-up with 147 respondents over 6 months, maintenance of prevention behaviors was strong in the areas of physical activity and hypertension management and significantly higher for people completing a greater number of Keys workshops. Prevention behavior can be activated in aging services settings and can be incorporated into daily routines.
