MENTAL AND BEHAVIOURAL DISORDERS (F00-F99)
In 2007, Mental and behavioural disorders (F00-F99) were identified as the underlying cause of 5,715 registered deaths, representing 4.1% of all registered deaths during 2007. This was an increase of 559 (11%) when compared with 2006.
There were nearly twice as many female deaths (3,613, 63%) due to Mental and behavioural disorders than male deaths (2,102, 37%) registered in 2007. The median age at death was higher for females at 88.5 years, compared with 84.4 years for males.
The number of deaths due to Dementia (F01-F03) increased substantially in 2006 (up 1,788 or 64% from 2005), due to an increased propensity for certifiers to identify Dementia as a cause of death (See Explanatory Note 67 for further information). In 2007, this has continued with 5,048 deaths attributed to this cause. Dementia accounted for 88% of Mental and behavioural disorders in 2007, compared with 89% in 2006. The sex ratio of 50 male deaths per 100 female deaths has remained relatively steady since 1998, with 1,686 males and 3,362 females dying of this disease in 2007. The median age at death for persons (87.8 years) dying of Dementia was higher than the median age for Mental and behavioural disorders (87.0 years) as a whole.
Mental and behavioural disorders due to the use of alcohol (F10) was the underlying cause of 291 (5.1%) deaths from Mental and behavioural disorders in 2007. More than three times more males than females died from this cause, with 228 male deaths compared with 63 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 was almost twenty years lower than the median age of all causes of death (80.5 years). The median age at death of females was 61.3 years, compared with 62.3 years for males. The trends for males and females differ also, with female deaths remaining steady since 1998 and male deaths fluctuating over time, ranging between 167 in 1998 and 229 in 2006.
