Abstract

Background: This paper aims to examine associations between pet ownership and symptoms of depression in a large, population-based sample of older adults. Specifically, we tested whether: (i) people who report more depressive symptoms are more likely to own a pet; (ii) pet ownership protects against an increase in depressive symptoms over time; (iii) associations differ by symptom type. Methods: Data were drawn from the English Longitudinal Study of Ageing, a longitudinal panel study of men and women aged 50 and older (n=7,617, 52.5% female). Pet ownership (dog/cat/other/none) was self-reported in 2010/11. Depressive symptoms were assessed in 2010/11 and 2016/17 using the 8-item Center for Epidemiologic Studies Depression (CES-D) scale. We analysed total CES-D score and derived symptom subscales (depressed mood, anhedonia, somatic symptoms) in relation to pet ownership, adjusting for sociodemographic and health-related covariates. Results: A one-symptom increase in total CES-D score was associated with 7% increased odds of dog ownership (OR=1.07, 95% CI 1.03-1.11). Significant associations were observed between each subset of depressive symptoms and dog ownership, with models run on z-scores showing a slightly stronger association for symptoms of depressed mood (OR=1.13, 95% CI 1.06-1.21) compared with anhedonia (OR=1.10, 95% CI 1.04-1.17) or somatic symptoms (OR=1.10, 95% CI 1.03-1.18). Prospectively, no significant associations were found. Limitations: Self-reported data; small sample size for some pet categories. Conclusion: Among older adults in England, those with more depressive symptoms are more likely to own a dog, but pet ownership is not significantly associated with change in depressive symptoms over time.
