title: [Seasonal variations in sudden death in sports clubs].
abstract: 2,825 cases of sudden deaths (2,669 men, 156 women) in sports-clubs between 1981 and 1999 were evaluated retrospectively by means of the cosinor method in order to detect a circannual distribution of occurrence. Deaths due to cardiovascular and traumatic events were additionally studied with regard to seasonal differences of frequency. The number of sudden deaths per month during a period of 19 years could be significantly fitted to a cosine model with a maximum in June, the absolute maximum value being observed in May (n = 317). In particular, accidents were more frequently found in spring and summer.
