<p><strong>Background: </strong>Seasonality in suicide has been investigated from the early 19th century to explore the productive environmental variables.<br>
Seasonality studies can provide information on prevention and interventions in suicide. In this study, we examined seasonality in<br>
suicide and aimed to explore the differences in seasonality between rural and urban areas, mental disorders, and genders.<br>
<strong>Methods:</strong> In this cross-sectional study, overall identified suicide cases in Ilam province from 21 March 2010 and 11 December 2014<br>
were identified, using systematic registration suicide data (SRSD). Two methods were used separately to analyze seasonality (Chisquare,<br>
Edwards' T). Seasonal effect (peak/ trough seasons) and (deaths/ attempts suicide) was explored by ratio statistics. The null<br>
hypothesis was that the completed suicides in each method group were evenly distributed over a year.<br>
<strong>Results:</strong> Significant seasonality was observed in suicide during the study period, with one peak in the spring and one in the winter.<br>
Our results showed that suicide seasonality following mental disorders was statistically significant with a peak in the spring, regardless<br>
of other factors such as gender and age. When all non- mental suicides are taken into account, the seasonality remains statistically significant,<br>
but the peak season is shifted to autumn.<br>
<strong>Conclusion: </strong>Investigating suicide in Ilam revealed a significant seasonality for both rural and urban areas, which was greater in the<br>
urban part. A significant seasonality in suicide was observed in attempters with mental disorders. In suicide attempters with mental<br>
disorders, findings showed two peaks in the spring and the autumn.</p>
