Brief Summary

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.

Conditions

Hypertension; Overweight; Obesity; Cardiovascular Diseases; Sedentary Behavior; Low Physical Fitness

Outcome Measures

Primary Outcomes (5)

• Change in Body mass index (height and weight)

  Baseline, 12 months, 36 months

• Change in blood pressure

  Baseline, 12 months, 36 months

• 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).

  Baseline, 12 months, 36 months

• 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.

  Baseline, 12 months, 36 months

• Change in mobility

  Mobility is measured as the time spent in an Eight-Foot-Up-and-Go test. Participants start seated in a chair, and are instructed to stand up, quickly circle a cone placed eight feet in front of the chair, and then sit back down in the chair. The stopwatch will start when the person fully stands up from the chair and stops when the person sits back down into the chair (recorded in seconds).

  Baseline, 12 months, 36 months

Study Arms (1)

Active Older Adults

Body mass index (height and weight), blood pressure and pulse, arm and leg strength and mobility

Behavioral: Active older Adults

Interventions

Active older Adults BEHAVIORAL

The 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.

Active Older Adults

Eligibility Criteria

• Age: 50 Years - 95 Years
• Sex: all
• Healthy Volunteers: Yes
• Age Groups: Adult (18-64), Older Adult (65+)
• Sampling Method: Non-Probability Sample

Study Population

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.

You may qualify if:

You may not qualify if:

• Aged less than 50 years, not residing in Miami-Dade County
