OT: Cool if true - new study indicates dog ownership associated with reduced CVD and mortality

A recent large study out of Sweden posted in the journal Scientific Reports indicated that dog ownership appeared to reduce cardiovascular disease and deaths over a 12-year period, presumably due to increased exercise and also companionship benefits, especially in single person households:

Dog ownership and the risk of cardiovascular disease and death – a nationwide cohort study

Abstract

Dogs may be beneficial in reducing cardiovascular risk in their owners by providing social support and motivation for physical activity. We aimed to investigate the association of dog ownership with incident cardiovascular disease (CVD) and death in a register-based prospective nation-wide cohort (n = 3,432,153) with up to 12 years of follow-up. Self-reported health and lifestyle habits were available for 34,202 participants in the Swedish Twin Register.
. . . In single- and multiple-person households, dog ownership (13.1%) was associated with lower risk of death, HR 0.67 (95% CI, 0.65–0.69) and 0.89 (0.87–0.91), respectively; and CVD death, HR 0.64 (0.59–0.70), and 0.85 (0.81–0.90), respectively. In single-person households, dog ownership was inversely associated with cardiovascular outcomes (HR composite CVD 0.92, 95% CI, 0.89–0.94). Ownership of hunting breed dogs was associated with lowest risk of CVD. Further analysis in the Twin Register could not replicate the reduced risk of CVD or death but also gave no indication of confounding by disability, comorbidities or lifestyle factors. In conclusion, dog ownership appears to be associated with lower risk of CVD in single-person households and lower mortality in the general population.
