Summary / Key Points
The crude mental health prevalence is
significantly worse than the England average.
Total contacts per 100,000 to Mental Health
Services are lower than the England Average.
The Island has the highest recorded crude rate
prevalence of Dementia in the UK.
The crude depression prevalence for the Island
is lower than the England average but not
significantly.
There is a significant difference across the
Island with the South Wight Locality presenting
a significantly higher recorded prevalence of
depression.
Suicide rates nationally are the third lowest in
Europe.
Suicide rates on the Island are highest
compared to our statistical neighbours but with
no significant difference due to small numbers.
Suicide rates are higher in males than females
across the country.
The level of population need
Mental Health
WHO describes Mental Health as “not just the absence
of mental disorder, but it is defined as a state of well
being in which every individual realises his or her own
potential, can cope with the normal stresses of life, can
work productively and fruitfully, and is able to make a
contribution to her or his community”.
The Mental Illness Needs Index 2000 is based on
illnesses severe enough to require hospital treatment
from time to time and is derived from data relating to
1998 and shows the predicted rates of admissions by
ward area. A score of 1 is the England average; overall
the Island scores 1.05 indicating that there is 5% higher
than average need for mental health services. The
darkest blue sections on the map show areas with the
greatest need with more than 23% higher than average
need. The four highest predicted areas are Ryde North
East and Ryde North West, Pan and Ventnor.
The crude mental health prevalence of the Island is
above the England prevalence of 0.82 with a
prevalence of 1.02 with a significantly worse than
average rate of hospital admissions for mental health
(nepho). Based on NHS funding the Island is not
significantly different to the England average for its
allocated spends on mental health per head (nepho).

Across the island the North and East Wight locality has
the highest prevalence of mental health but there is no
significant difference when benchmarking between the
three localities. Adult and elderly secondary mental
health services on the Island are being used at a
significantly higher rate than the England and South
East rate (nepho).
The Islands prevalence of mental health has been
significantly higher than the England’s average over the
last five years and has increased by 8% since 2006/07
however the growth of mental health prevalence on the
island has been much slower than the national growth
of 11%. The number of total contacts with mental
health services per 100,000 populations for 2010/11
was 32, significantly lower than the England rate of 313
per 100,000. This measure includes all contacts with
mental health staff, including Psychiatrists, Community
Psychiatric, Nurses, Clinical Psychologists,
Occupational Therapists, Physiotherapists, Consultant
Psychotherapists and Social Workers (nepho)
Dementia
Dementia is a syndrome characterised by the
catastrophic, progressive global deterioration in
intellectual function and is a main cause of late life
disability (nepho). As we age the prevalence of
dementia increases and therefore areas with higher
elderly populations will have higher rates of recorded
dementia. Dementia is more common in older people
but can affect people at any age with one in 14 people
over the age of 65 and one in six over the age of 80
having some form of dementia (PSSRU).
The Island had the highest recorded prevalence of
dementia in the UK for 2011/12 which is linked with
additional psychiatric symptoms such as adjustment
disorder, anxiety, psychiatric symptoms and alcohol
related issues.
Across the Island the South Wight Locality has the
highest recorded rate of dementia but with no statistical
difference between the three. Dementia goes
undiagnosed in a lot of people with many not having
access to care that could be available to them.

Isle of Wight: Estimated Prevalence of Dementia: Number of People Age 65+ - by Gender
Male Female
Data Source: Projecting Older People Population Information System (POPPI)
Dementia prevalence has increased on the island over
the last five years and nationally. In terms of numbers
there has been an increase of 66.5% registered with
dementia and a total increase from 0.6% to 1% total
prevalence compared to the national prevalence of
0.4% in 2006/07 to 0.5% in 2011/12.
The prevalence rates have been applied to the ONS
population projections of the 65 and over population to
give estimated numbers of people predicted to have
dementia up to 2020. It is predicted there will be a
further 21% increase in registered dementia prevalence
by 2020.
Across the predicted years the largest predicted age
group increase is in the 70-74 years olds with a
predicted rise of 44% from 2012 to 2020 followed by the
90+ age group with a 33% increase. There was an
increase in all age groups with the exception of the 65-
69 age groups with a predicted 9% decrease.
The increase by gender from 2012 to 2020 is predicted
to be larger in males with a predicted 32% increase
compared to a predicted 16% increase in females.
The Delphi consensus was used to estimate the
numbers of people with dementia. This method is used
to predict estimates when an evidence base exists but
the recorded data is incomplete. It is believed that
there is a much higher rate of dementia than the
recorded prevalence which suggests that there are still
many people who have not been diagnosed and appear
on the Dementia register. On the Island it is estimated
that there could have been another 1,245 people in
2012 with Dementia on the Island that have not been
receiving correct medical help.

Depression
The symptoms and severity of depression can affect
people in different ways and vary from person to
person. In its mildest form someone may feel
persistently low in spirit but at its most severe,
depression can make someone feel suicidal and that
life is no longer worth living (NHS). Depression is quite
common and can affect around one in ten of us at some
point including young and old, men and women.
The Island in comparison to similar areas has a lower
rate of registered depression and is significantly below
the England average.
Across the Island there is a significant difference
between the three localities with South Wight having a
higher crude rate of registered depression with 11.7%
of patients registered compared to the West & Central
Wight Locality of 5.2% and the North & East Wight
Locality of 6.4%.
Over the last four years the registered depression rate
has increased at the same rate as the England increase
rate with a significant rise from 2008/09 to 2009/10 due
to a change in recording.
The Island is slightly above the England average for
prescribed anti depressants per therapeutic group
population.
Suicide
“Suicides are one of the main causes of lost years of
life after circulatory diseases and cancers” (SEPHO,
2006). In comparison to other countries in Europe, the
United Kingdom has a relatively low suicide rate. Out
of 18 countries in Europe the UK has the third lowest
rate and the 13th lowest out of 57 major countries in the
world (SEPHO 2006).

Suicide rates on the island are highest compared to its
comparators but there is no significant differences
which is due to small numbers.
Suicide rates across all the areas are significantly
higher in males than in females with no significant
differences across the areas.
Suicide mortality rates across the island have increased
year on year since 2004-06 compared to the England
rate which has slightly decreased. It is important to
note that, because of the relatively small number of
deaths of IW residents each year from suicide, even
three-year aggregated mortality rates are susceptible to
fluctuation. A small change in the annual number of
deaths can result in a significant change in the mortality
rate.
