Background: Dog ownership has been associated with increased physical activity in the general adult population.
Objective: The objective of this study was to examine dog ownership and dog walking and their relationship with home-based and Phase II cardiac rehabilitation exercise, depression, and hopelessness in patients with ischemic heart disease (IHD).
Methods: A total of 122 IHD patients were included in this prospective observational study. Patients completed dog ownership/walking questions during their hospitalization. The Cardiac Rehabilitation Exercise Participation Tool, Patient Health Questionaire-9 (PHQ-9), and State-Trait Hopelessness Scale were completed by mail at 3, 8, or 12 months later. Regression modeling was used to evaluate the significance of dog ownership/walking on exercise, depression and hopelessness.
Results: The sample was 34.4% female and had a mean age of 64.7±9.1 years. Forty-two patients (34.4%) reported owning a dog. Patients who owned, but did not walk their dog, reported significantly lower levels of home exercise compared to patients who walked their dogs at least 1 day/week (non-dog walkers: 36.8% vs. dog walkers: 73.9%, p=0.019). The odds of participating in home exercise were significantly higher for dog walkers compared to non-dog walkers (OR 8.1 [1.7, 38.5] vs. 1.0). There were no differences in Phase II cardiac rehabilitation exercise, depression or hopelessness between dog owners and non-dog owners or between dog walkers and non-dog walkers.
Conclusions: These findings show a beneficial effect on home-based exercise for those who dog-walk at least 1 day/week. Health care professionals should encourage dog walking to increase dog owners’ physical activity levels
