The World Health Organization (WHO) recognizes the impact of social determinants of health (SDHs) on human health and wellbeing factors. Limited research has explored how SDHs, such as the social, economic, and environmental conditions in which individuals are born, live, work, and grow older, shape exercise behaviors and chronic health conditions such as cancer in dogs. This study links SDHs identified through owner-provided continental United States zip codes with levels of physical activity. We hypothesized that owners with higher incomes, education, and access to healthcare services positively influence their dog’s health outcomes, specifically owner-reported physical activity. Our study utilized all owner-provided data, collected between 2012 and 2022, from the first seven years of owner surveys for the 3044 Golden Retrievers enrolled in the Morris Animal Foundation Lifetime Study. Sixteen GPBoost Poisson models were built to assess the impact of twenty-three social determinants in Golden Retrievers with and without a diagnosis of cancer. SHAP values were calculated for each dependent variable. Consistently, economic factors, education, ethnicity, and health care access were identified as important variables. Furthermore, our findings suggest that complex interactions between ethnicities and other SDHs should be explored in future studies.
