Parasuicide and the lunar cycle

  • Tim D. Rogers (a1), George Masterton (a1) and Ralph McGuire (a1)


Admissions to hospital following parasuicide in one city over eighteen years exhibit a cyclical variation apparently synchronized with the lunar quarters. The effect would only account for approximately 0·7 out of the average of 46 parasuicides per 100000 adults per lunar cycle (95% CI 0·6–0·8), and fails to reach statistical significance.
