Gender differences in antidepressant use-related seasonality change in suicide mortality in Hungary, 1998–2006

Abstract
Objectives. Studies show that the seasonality of suicide (spring/early summer peak, winter low) is mainly the consequence of the seasonal incidence of depression-related suicides. The aim of the present study was to analyse the relationship between increasing antidepressant utilization and national suicide rate of Hungary between 1998 and 2006, with particular regard to seasonal patterns and gender differences. Methods. Time trend analysis (ARIMA) had been applied to investigate the correlation between the trend of antidepressant prescription and both of suicide rates and seasonality index. Results. During the 9 years of the study period there was a significant (PConclusions. The results suggest that decreasing seasonality of suicides could be a good marker of lowering rate of depression-related suicides in the population particularly among males.
