MENTAL AND BEHAVIOURAL DISORDERS (F00-F99)
In 2006, Mental and behavioural disorders (F00-F99) were identified as the underlying cause of 5,156 registered deaths, representing 3.9% of all registered deaths during 2006. This is an increase of 1,789, a 53% increase when compared with 2005.
There were more than twice as many female deaths (3,296, 64%) due to Mental and behavioural disorders than male deaths (1860, 36%) registered in 2006. The median age at death was higher for females at 88.6 years, compared with 84.0 years for males.
Dementia (F01-F03) accounted for 89% of Mental and behavioural disorders in 2006, compared with 83% in 2005. Tthe number of deaths due to Dementia increased substantially from 2,788 in 2005 to 4,576 in 2006. This increase is the main contributor to the increase in the total number of deaths due to Mental and behavioural disorders from 2005 to 2006. The sex ratio of 48 males per 100 female deaths has remained relatively steady since 1997 with 1,486 males and 3,090 females dying of this disease in 2006. The median age at death for persons (87.9 years) was higher than the median age for Mental and behavioural disorders (80.3 years) as a whole. See Explanatory Note 66 for a more detailed explanation of the increase in deaths due to Dementia.
Mental and behavioural disorders due to the use of alcohol (F10) was the underlying cause of 286 (5.6%) deaths from Mental and behavioural disorders in 2006. Four times more males than females died from this cause, with 229 male deaths compared with 57 female deaths. The median age at death of persons with Mental and behavioural disorders due to the use of alcohol as the underlying cause of death was 61.9 years. This is almost twenty years lower than the median age of all causes of death (80.3 years). The median age at death of females was 56.6 years, compared with 62.6 years for males. The trends for males and females differ also, with female deaths remaining steady since 1997 and male deaths fluctuating over time, ranging between 167 in 1998 and 229 in 2006.
