Associate Professor Tetsuya Matsubayashi of Osaka University Graduate School and Michiko Ueda Research Assistant Professor of Syracuse University conducted a statistical survey of all people who died in Japan from 1974 to 2014. Turned out to be more than the other days.Although it has been confirmed that the number of deaths on birthdays is increasing overseas, it is the first time that the situation in Japan has been confirmed.
According to Osaka University, Associate Professor Matsubayashi et al. Analyzed the relationship between the birthdays and death dates of about 1974 million people who died from suicide, traffic accidents, drowning, choking, and falling from 2014-207 vital survey data. bottom.
As a result, suicides were particularly affected by birthdays, with birthday suicides being about 50% higher than on other days.In addition, the number of traffic accidents such as passenger cars and motorcycles, drowning, and death from falling was 20 to 40% higher than on other days.
Two hypotheses have been proposed for the risk of death before and after the birthday.There is a theory that the mortality rate of a birthday will decrease by trying to live until a day that is meaningful to you, such as a birthday, and if you do not spend the anniversary as expected, mental stress such as loneliness will accumulate and the mortality rate will increase. The theory is that it will increase.
Recent studies in Europe and the United States have confirmed that the number of deaths is increasing, and it has become clear that the same tendency is seen in Japan, which has a different culture.For this reason, Associate Professor Matsubayashi and his colleagues believe that it is necessary for family members, friends, and doctors to pay special attention and provide more support than usual when people at high risk of suicide reach their birthdays.
