Seasonality of Suicide: Relationship With the Reason for Suicide

This study tested the hypothesis that suicides that can be attributed to a psychiatric illness show a higher seasonality than suicides due to any other reason. All suicides registered in Italy from 1984-2000 were analyzed with circular statistic techniques. Suicides attributable to a psychiatric illness showed a significantly higher seasonal unevenness than the suicides attributable to somatic illness, sentimental, or economic reasons. (35 refs.)
