The Active Older Adults prospective cohort study examines the effects of a park-based fitness program on cardiovascular fitness outcomes for older adults (aged 50 years and older). Duke will perform a secondary analysis of the data collected as part of the Active Older Adults prospective cohort study run by Miami-Dade County Parks and Recreation.
Aged 50 years or older, residing in Miami-Dade County
All participants enrolled in the Miami-Dade Active Older Adults study will be included in this secondary analysis
Aged less than 50 years, not residing in Miami-Dade County
Anyone not enrolled in the Miami-Dade Active Older Adults study will be excluded from this secondary analysis
Active Older Adults is offered in Miami-Dade County (MDC), FL where 40.9% of people older than 65 are sedentary (did not participate in any leisure-time activities, physical activities other than their regular job, during the past month). Within MDC, age-adjusted death rates per 100,000 population (2020-2022) from cardiovascular disease were higher for both Black (291.8.7 vs. 263.4) and Hispanic (179.2 vs. 171.2) residents of MDC vs. statewide, respectively, compared with White (186.2 vs. 198.7) residents. This disparity is particularly relevant for MDC where 69% of people identify as Hispanic or Latino and 17% identify as Black, as opposed to about 19% and 14%, respectively in the United States and 27% and 17% respectively in Florida.
Cohort
Prospective
Active older Adults
BehavioralThe program entails one-hour sessions two or three times per week including aerobic workout, strength training, balance and flexibility exercise delivered online or in-person. Miami-Dade Parks and Recreation is the sponsor of the Active Older Adults prospective cohort study. Duke is conducting a secondary data analysis on data collected as part of the Active Older Adults study.
Change in Body mass index (height and weight)
Change in blood pressure
Change in arm strength
Participant arm strength is measured as the total number of arm curls performed in 30 seconds. Participants are seated in a chair while holding a dumbbell or cuff weight (5lb for women and 8lb for men) wrapped around their right or left wrist (the left wrist is employed when the right wrist is impractical).
Change in leg strength
Leg strength is assessed as the number of chair stands a person could complete in 30 seconds. For one chair stand, participants get up from their seats (with assistance if necessary) and then sit back down.
