Dog ownership is linked to a living a longer, stronger life – Inverse

According to a study and separate meta-analysis published this month in the journal Circulation: Cardiovascular Quality and Outcomes, owning a dog is associated with living a longer life, especially among those who have survived heart attacks and strokes.

“These studies provide good, quality data indicating dog ownership is associated with reduced cardiac and all-cause mortality,” Glenn Levine, M.D., a professor of medicine at Baylor College, explained as outside commentary. “While these non-randomized studies cannot ‘prove’ that adopting or owning a dog directly leads to reduced mortality, these robust findings are certainly at least suggestive of this.”

Dogs and the human heart

The first study used the Swedish National Patient Registry to identify patients between the ages of 40 and 85 who suffered an ischemic stroke or heart attack sometime between 2001 and 2012. Of the 181,696 individuals who experienced a heart attack, 5.7 percent owned a dog. Meanwhile, 4.8 percent of the 154,617 stroke-sufferers owned a dog as well.

The scientists discovered that, compared to people who did not own a dog, the risk of death for dog-owning heart attack patients who lived alone was 33 percent less. Meanwhile, the risk of death of dog-owners who lived with a partner or child was 15 percent risk.

Dog owners were more likely to survive strokes and heart attacks.

When it came to the stroke patients, a similar trend emerged. The risk of death for those who lived alone, save for their dog, was 27 percent lower and 12 percent lower for those who also lived with a partner or child.

The study authors hypothesize that these results emerged because people with dogs are likely more active and less lonely. Social isolation is a strong risk factor for premature death — and owning a dog inherently means that a person has to enter the world.
