RESUMO
Optimizing duration of participation in health promotion programs has important implications for program reach and costs. We examined data from 355 participants in EnhanceWellness (EW) to determine whether improvements in disability risk factors (depression, physical inactivity) occurred early or late in the enrollment period. Participants had a mean age of 74 years; 76% were women, and 16% were non-white. The percent depressed declined from enrollment to six months (35% to 28%, p = .001) and from six to 12 months (28% to 22%, p = .03). The percent physically inactive declined over the first six months, without substantial change thereafter (47%, 29%, and 29%). Those remaining inactive at six months had worse self-rated health and more depressive symptoms initially; a subset of those increased their physical activity by 12 months. These data suggest that enrollment could be reduced from 12 to six months without compromising favorable effects of EW participation, although additional benefits may accrue beyond six months.
RESUMO
OBJECTIVE: To describe challenges in disseminating the Health Enhancement Program (HEP), a community-based disability prevention program for community dwelling elders, and to examine program effectiveness in geographically dispersed sites. METHODS: Within-group, pre-test-post-test comparisons of disability risk factors, health and functional status, and hospitalizations for 115 participants completing one year in HEP, and primary care provider awareness and perceptions of the program. RESULTS: Most (77%) participants were women, with an average age of 73 years and an average of 3.5 chronic conditions. At one-year follow-up, compared with enrollment, fewer participants were depressed (8.8% vs 15.9%), physically inactive (15.8% vs 38.6%), at high nutritional risk (24.3% vs 44.1%), or experiencing restricted activity days (35% vs 48%). Severity scores on most measures also improved significantly. The proportion hospitalized was unchanged from the year prior to HEP, although risk factors predicted an increase in hospitalizations as for the control group in the randomized trial. CONCLUSIONS: HEP reduced participants' disability risk factors. Sites varied on numbers enrolled and time to implement the program, likely due to differing referral bases, degree of physician awareness of HEP, and site readiness. However, the benefits of HEP participation were comparable with those reported previously.
