Assault

Assaults are a serious public health concern, as it can lead to greater emotional, mental and physical morbidity as well as mortality[1]

The NWHU monitors trends of mortality and hospitalization from assault in the catchment area, which have been considerably higher than provincial rates in recent years.

Mortality

From 2007 to 2011, mortality rates were slightly higher on average within the NWHU area compared to the province, but the difference was only statistically significant in 2009 and 2010, which were peak years. The NWHU had an average rate of 5.7 deaths per 100,000 per year while the province had 1.4 deaths per 100,000 per year.
 
On average, mortality rates in males in the NWHU were just under three times as high as in females (8.6 cases per 100,000 per year vs 2.9 cases per 100,000 per year), with the difference being statistically significant.
