Answer

Researchers examined the association between birthday and increased risk of suicide in the general population as well as in patients receiving mental health services. Using Poisson regression analysis, they observed an increased risk of suicide on day of one's birthday itself for males in both the general population (IRR = 1.39, 95% CI = 1.18-1.64, p < .01) and the clinical population (IRR = 1.48, 95% CI = 1.07-2.07, p = .03). This increased risk was especially significant in males aged 35 years and older. In the clinical population, risk was restricted to male patients aged 35-54 and risk extended to the 3 days prior to one's birthday. These results suggest that birthdays are periods of increased risk of suicide, particularly for men, regardless of whether or not they are receiving psychiatric care.
