“반려견 키우는 노인, 치매 위험 48% 낮아”

A recent study has found that dog owners in Japan are 48% less likely to develop dementia compared to non-dog owners. The research, conducted by the National Institute of Environmental Studies in Tokyo, the Health and Longevity Center of Tokyo, and a team from Tokyo University, analyzed health data of 11,224 residents aged 65 and above in Tokyo.

The data was collected between 2016 and 2023. The study revealed that those who owned dogs had a significantly lower risk of developing dementia and also had a 37% lower mortality rate compared to those who did not own dogs. The researchers suggest that this could potentially lead to a savings of 5920 billion yen (5.3 trillion USD) in medical and caregiving costs over a period of four years.

The researchers attribute the reduction in dementia risk to lifestyle changes, such as increased moderate physical activity from daily walks with the dog, and expanded social interaction with neighbors. Additionally, they note that the emotional bond with the dog can help alleviate feelings of loneliness and promote the release of oxytocin, a hormone that reduces stress.

Despite these benefits, the number of elderly individuals owning dogs in Japan is alarmingly low, accounting for only 8.6% of the study participants, and even fewer (13.4%) expressed interest in getting a dog. This suggests that many elderly people are hesitant to own dogs due to health issues or other concerns. To address this, the National Institute of Environmental Studies' chief researcher, Danikuchi Yu, urges the development of a system that allows elderly pet owners to continue caring for their animals until the end of their lives, ensuring they can live safely with their furry companions.
