Peer Empowerment Program for Physical Activity in Low Income and Minority Seniors (PEP4PA)

July 9, 2021 updated by: Loki Natarajan, University of California, San Diego

PEP4PA - Peer Empowerment Program for Physical Activity in Low Income and Minority Seniors

Older adults are the least active population group in the US. Yet, research has shown that an increase in physical activity (PA) can have immediate and profound effects on cardiovascular health. Older adults who are active use significantly fewer health care resources, and with the increasing number of older adults in the US it is imperative to curb health care expenditure in this group. PEP4PA (Peer Empowerment Program 4 Physical Activity) is a multilevel intervention aimed at increasing physical activity levels in a population of low income and ethnically diverse older adults. It will be delivered in centers by trained older adults. Participants will work towards a daily increase of 2000 steps per day through self-paced incidental walking, peer led group walks, and attendance at existing center PA classes. They will also work on projects to increase opportunities to be physically active at their center or in the surrounding neighborhood.

Detailed Description

In a 2-year cluster randomized controlled field trial of 408 ethnically diverse, older adults (50+ years old) in 12 low income community centers serving seniors in San Diego County the investigators will investigate:

  1. The efficacy of PEP4PA (Peer Empowerment Program 4 Physical Activity) to reduce disparities in PA by increasing the percentage of participants achieving 150 minutes of PA per week at 6 and 12 months. Hypothesis: Participants in PEP4PA will significantly increase PA minutes in moderate intensity (measured objectively by accelerometry) to a greater extent than older adults receiving usual care (e.g. normal PA programing) in control centers and a greater percent will meet NHANES criteria for weekly PA.
  2. The efficacy of PEP4PA to improve physical functioning, blood pressure (BP), depressive symptoms and quality of life. Hypothesis: Participants in PEP4PA will significantly increase their physical functioning (measured objectively by the short physical performance battery and 6 minute timed walk), decrease their systolic BP (mmHg) and reporting of depressive symptoms, and improve their quality of life scores (measured at baseline, 6 & 12 months) to a greater extent than older adults in control centers.
  3. Assess the incremental cost effectiveness ratio (ICER) of PEP4PA in terms of cost per MET hour and cost per QALY compared to usual programming in the control centers at 12 months.
  4. Evaluate the impact of PEP4PA on secondary outcomes such as sedentary time and sleep quality (measured by accelerometry), cognitive/executive functioning, and walking routes (from GPS) at 12 months.

Exploratory aims: 5. Examine individual, interpersonal, organizational, and environmental factors that affect implementation & behavior change. 6. Assess the efficacy, effectiveness and ICER of PEP4PA at 24 months

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Physical Activity
The program will be run by peer Leaders and senior center staff with the support of UCSD staff. Participants will work towards a 2000 increase in daily steps through self-paced incidental walking and peer led group walks.
Behavioral: Physical Activity
intervention activities will remain at the daily level, including using pedometers, having daily goals, attendance at Peer lead group walks and recognition of efforts through monthly celebrations and bi-weekly goal tracking with peer Health Coaches.
No Intervention: Usual Care
Measurement at baseline, 6, 12, 18 and 24 months only with a health related event at each time point.
