Seasonal variations in suicide mortality in Canada: A nationwide analysis
This study confirms seasonal patterns in suicide mortality in Canada, peaking during the summer months. Such patterns are more prominent and stable among males, and its amplitude was larger among older adults. Contrary to the common perception that suicide rates peak in January, our findings show a summer peak. Future research should explore the underlying mechanisms driving these seasonal variations and their demographic differences.
