I think this study examines whether people have a higher risk of death on and around their birthdays using large national mortality data. We examined the death records of individuals who died in Japan due to a major external cause. Poisson regression analysis showed that people are more likely to die on their birthdays than on other calendar days by suicide, traffic accidents, accidental falls, drowning and choking. Especially for suicide cases, about 50% more people may die on their birthdays compared to other dates. Excess deaths on birthdays are observed regardless of gender, marital status, and age-in-death subgroups. For suicide deaths, our results provide strong support for the "blues birthday" hypothesis that predicts an excess mortality on birthdays. With regard to traffic accidents and other accidental accidents, however, our results show that excess mortality on birthdays may be related to birthday celebrations. For the elderly population, our analysis shows that special activities associated with birthday celebrations, which often involve out to consume festive foods and drinks, may become contributors to the sudden increase in the number of accidental deaths on their birthdays. In contrast, a sharp increase in the number of motor vehicle accidents is observed in individuals in their 20s on birthdays, which may be due to birthday celebrations involving driving and drinking. But most people also celebrate their ulanh year as a festive over the age of the creator.
