Evaluation of a Medical Fitness Referral Program at a Single Institution From 2015 to 2022

Purpose: To assess whether biometric data of participants (i.e., weight, body mass index (BMI), body fat percentage (BFP), heart rate, and blood pressure) would be statistically different from pre- to post-program assessments after completion of a single institution medical fitness referral program. Methods: This is a retrospective analysis of randomly selected participants from August 2015 to December 2022. Analysis of variance was performed for each outcome with groups separated by gender, age, and time period relative to COVID. Results: Analysis included 984 participants, 653 (66%) were female, mean age was 55.5 years (SD = 14.9) with 297 (30%) of participants ≥65, and 747 (76%) completed the program prior to COVID. Significant mean reductions from pre- to post-program were seen for BMI (−.43, SD = 1.16), weight (-2.69 pounds, SD = 7.44), BFP (.44%, SD = 2.35%), systolic blood pressure (3.33 mmHg, SD = 14.58), and diastolic blood pressure (2.18 mmHg, SD = 8.65). Additional significant interactions identified: weight difference for participants less than age 65 (−3.16, SD = 8.31) vs participants ≥65 (−1.60, SD = 4.66), P = .003. Conclusions: In this analysis, participants of the program from August 2015 to December 2022 were seen to have statistically significant reductions in the delineated biometric parameters. However, due to limitations, specific conclusions regarding causation cannot be drawn.
