Investigating the Outcomes of a Physical Activity Program offered to Older Adults in South Florida and Understanding the Correlates of Completion

Despite the well-known benefits of physical activity, in 2012, only 37.5% of older adults aged 60 years or older met recommended aerobic physical activity levels and 16.1% met muscle-strengthening guidelines. Effective exercise programs can help combat the problem of inactivity but 50% of those who start participating in an exercise program drop out within first few weeks, preventing them from gaining any health benefits. Since fall 2008, the Healthy Aging Regional Collaborative of South Florida has offered EnhanceFitness (EF), an evidence-based physical activity program to older adults. This dissertation compared EF effectiveness at 4-, 8-, and 12-months and examined the factors that were associated with program completion. A paired sample t-test identified changes at 4-months and repeated measures design was used to identify changes from baseline to 4-, 8-, and 12- months. Logistic regression was used to identify correlates associated with completion. Between October 1, 2008 and December 31, 2012, 4,531 older adults (\u3e=60 years) attended one or more EF sessions. Participants showed significant improvement in the number of chair stands performed in 30-seconds with mean change of 1.7, 1.6, and 2.0 respectively at 4-,8-,and 12- months (pp\u3c0.001). Results suggest Black, non-Haitian men were less likely to complete the program when compared to white, non-Hispanic men (OR=0.41, p=0.02). Men who self-reported having at least one risk factor were more likely to complete the program (OR=1.81, p= 0.03). In addition, women who lived in Miami-Dade County (OR=2.13, ppppp\u3c0.01). Effectiveness results revealed that all participants improved on outcome measures. However, improvement is more than double for those who completed recommended sessions (

Evaluation of a Community-Based Falls Prevention Program in South Florida, 2008-2009

Introduction Many older adults experience fear of falling, which may reduce participation in routine activities. A Matter of Balance (MOB) and Un Asunto de Equilibrio (ADE) workshops were offered in South Florida to reduce fear of falling and increase activity levels in older adults. The objectives of this study were to evaluate the effectiveness of the lay leader model of the programs in the first year of their implementation and to further report on participant outcome measures. Methods We analyzed reach, adoption, and implementation data for participants who attended workshops between October 1, 2008, and December 31, 2009, who were aged 60 years or older, and who had both baseline and posttest outcome data. Workshops were in English and Spanish and consisted of 8 two-hour sessions. Participants completed a 7-item baseline and posttest questionnaire that consisted of a falls management scale, a social activity item, and modified version of Physician-Based Assessment and Counseling on Exercise. We analyzed outcome data on multiple characteristics using a general linear model. A class evaluation questionnaire measured participant satisfaction. Results Results for 562 participants who provided both baseline and posttest data showed significant improvement on 6 of 7 questions for MOB and all questions for ADE (P \u3c .001). The 391 participants who provided evaluation data indicated that the programs were effective, beneficial, and well organized. Conclusion Lay leaders successfully implemented the programs in community settings. The programs were effective in reducing fear of falling among older adults

Breast cancer screening practices of safety net clinics: Results of a needs assessment study

<p>Abstract</p> <p>Background</p> <p>For low income and uninsured populations, safety net clinics are an important source of health care, including preventive services such as mammography screening. However, little is known about how well breast health is coordinated within the safety net clinic environment and what barriers patients encounter.</p> <p>Methods</p> <p>A needs assessment was conducted among eight community-based safety net clinics located in Montgomery County, Maryland to learn about breast cancer referral and screening procedures. Structured in-depth interviews were conducted with clinic staff during the summer of 2008.</p> <p>Results</p> <p>Safety net clinics reported that they routinely identified women who need mammography screening and referred women to mammography screening facilities. However, clinics were not aware of the limited number of free or low cost mammography screening slots available in the county or the waiting time to receive mammography services. Overall, screening barriers were common in the safety net system and only a few procedures were in place to help women overcome these barriers.</p> <p>Conclusion</p> <p>Safety net clinics face multiple barriers in providing and coordinating breast cancer screening services for low income or uninsured patients. These barriers prevent the efficient allocation of mammography screening services and prevent underserved women from accessing an important preventive health service.</p

Implementation of an Evidence-Based Exercise Program for Older Adults in South Florida

Introduction. This study aimed to examine how well an evidence-based physical activity program could be translated for wide scale dissemination and adoption to increase physical activity among community-dwelling older adults. Methods. Between October 2009 and December 2012, reach, fidelity, dosage, ease of implementation, and barriers to translation of EnhanceFitness (EF) were assessed. To assess effectiveness, a pretest-posttest design was used to measure increases in functional fitness (chair stands, arm curls, and the up-and-go test). Results. Fourteen community-based agencies offered 126 EF classes in 83 different locations and reached 4,490 older adults. Most participants were female (72%). Thirty-eight percent of participants did not complete the initial 16-week EF program. The 25% who received the recommended dose experienced an increase in upper and lower body strength and mobility. Further, participants reported high satisfaction with the program. Conclusion. EF was successfully implemented in a variety of settings throughout South Florida and reached a large number of older adults. However, challenges were encountered in ensuring that those who participated received a program dose that would lead to beneficial gains in functional fitness
