Research Title:
Creating dementia-friendly urban environment to promote social inclusion,
independent living and reducing risk of dementia amongst older Londoners:
urban health and social intervention
ABSTRACT
Dementia is a major challenge we are facing in our society. This research investigates the effect of
street mobility and network accessibility on people living with dementia in early stage and their
carers. These will focus on the impact of community severance (traffic or volume) on leisure time
physical activity and social interaction amongst older people living with dementia and their carers.
Community severance occurs where road traffic (speed or volume) inhibits access to goods, services,
or people. The aim of this research is to consider how social and lifestyle changes may help to
reduce the risk of dementia and disability amongst older Londoners who are living with dementia in
early stage. The study will be assessed and identify community severance within Older and Disable
Lo do er s Developments where proposed by Great London Authorities in 2013 (GLA 2013).
Although community severance diminishes social contacts, the implications of community severance
for morbidity and mortality have not been empirically established. There is empirical evidence that
traffic speed and olu e redu es physi al a ti ity, so ial o ta ts, hildre s play, a d a ess to
goods and services. However, no studies have investigated mental or physical health outcomes in
relation to community severance.
1. BACKGROUND
There are 800,000 people living with
dementia in the UK (Department of Health
2013); and the financial cost of dementia in
the UK is £23 billion and globally it is
approaching $600 billion. Prime Minister
David Cameron led G8 Dementia Summit last
December to set out plans for supporting
people with dementia- and their carer and to
develop co-ordinated global action on
dementia, stimulating greater investment and
innovation in dementia research.
Dementia is the loss of intellectual ability. The
early stage of dementia is often overlooked,
because the onset is gradual. Common
symptoms include: forgetfulness, losing track
of the time, becoming lost in familiar places
(WHO 2012). Early dementia diagnosis and
post-diagnosis support is increasingly a key
element in supporting independence and
quality of life for people with early stage
dementia and their carers. As people with
dementia receive an earlier diagnosis this
presents challenges for the person and their
carer about how they cope and the type of
help they require (NHS 2008).
With limited spaces available in care facilities,
most older people with mild to moderate
dementia live in their own homes. (Burton
2006). Research has shown that remaining in
the familiar surroundings of home and the
local neighbourhood can have beneficial
effects cognitively, physically and emotionally.
However, to live successfully in the
community people with dementia need
outdoor environments that are designed
inclusively to help them to get involve
physically and socially. If they are unable to
enter or use their local neighbourhoods they
will become effectively housebound. (Mitchell
2006).
Social interaction and physical activity in
outdoor environment offers physical,
sociological and psychological benefits for
older people with dementia. Various ways of
promoting an alternative model focusing on
social inclusion are explored by Cantley and
Bo es 2004 . These i lude heari g the
oi es of people ith de e tia a d their
views and feelings about how they want to
live. This approach is supported by Wilkinson
(2002) who argues the case for including
people with dementia in research to increase
understanding of their quality of life so that
we can reduce barriers to participation and
bring them more inclusively into society.
There is evidence that the more that older
people walk and take exercise the less their
risk of dementia (Abbott et al, 2004; Scherder
et al, 2005; Larson et al, 2006). Longitudinal
study has found that frequent participation
(daily-weekly) in social activities is conducive
to a decreased risk of dementia (Wang, Karp,
Winblad, & Fratiglioni, 2002). In the UK, more
than 80 percent of people aged between 65
and 74 years old do not meet the
recommended level of physical activity (Joint
Health Survey Unit, 2004; Scottish Executive,
2005).
There is need to understand the impact of
community severance on social interaction,
leisure time physical activity and factors that
contribute to quality of life amongst older
people in the early stages of dementia from
their own perspectives. The outcome would
inform public health and urban transport
policy makers, academic researchers and
dementia friendly community agencies to
design social intervention and creating
dementia
friendly
environment
and
promoting independent living amongst older
people living with dementia in early stage and
their carers.
Residents living on busy streets have smaller
social networks; people with fewer social
contacts have worse physical and mental
health. This study considers community
severance, dependent older people living with
dementia and their carers, social isolation,
physical inactivity, street mobility and
network accessibility in outdoor environment
as urban transport, public health problems,
which cannot be solved by individuals
themselves. Integrated and cross-disciplinary
approaches can overcome these problems.
This research will employ evidence informed
model of potential determinants of
sport/physical activity (Foster, 2005), Agefriendly environment approach (WHO, 2007),
street for life concept Dementia-friendly
environment audit (Burton, 2006), pedestrianfriendly approach, and Healthy Urban
Planning approach (Barton, 2006) to evaluate
the environmental features and its impact on
health and older age. Urban transport
solutions informed by physical activity
concerns and social and-psychological
approach which will take more account of an
i di idual s parti ular life history, life style,
social, cultural terms and how it impacts on
experiences of dementia in early stage.
AIMS and Research Question(s)
The aim of this research is to identify how the
social and lifestyle changes may help reduce
the risk of dementia and disability; and to
consider to what extend street mobility and
network accessibility can influence leisure
time physical activity and social interaction of
older people living with dementia and their
carers. This research seeks evidence to
answer the following questions: To what
extend social and lifestyle changes may help
to reduce the risk of developing dementia and
disability in the early stages? How to enhance
and extend the active participation of older
people with dementia in their local
community? What is the role of community
severance on social interaction, leisure time
physical activity and lifestyle change amongst
older Londoner living in early stage of
dementia? What features of the built
environment facilitate or hinder leisure time
physical activity and social interaction in
outdoor places amongst older people with
dementia? To what extend street mobility and
accessibility network to public realm increase
leisure time physical activity and social
interaction amongst older people living with
dementia?
OBJECTIVES
There are five objectives will be addressed:
1) to explore the priorities of older people
with dementia in community severance, and
their needs in outdoor environments where
may enhance their active participation on
their local community.
2) to explore how changes in individual
lifestyle, social interaction and leisure time
physical activity, may reduce risk of dementia
amongst old people living in early stage.
3) to develop a method / questioner tools to
measure community severance at individual
level and design social intervention to assess
the effect of social change, physical activity on
older people living with dementia in early
stage.
4) to evaluate effect of community severance,
shared-space, busy street, home zone and
car-free environment on social interaction,
leisure time physical activity and quality of life
amongst older people with dementia and
their carers.
5) to evaluate and coordinate clinical trial of
memory services across London to
understand
the
effect
of
outdoor
environment, social interaction and leisure
time physical activity on older people living
with dementia and their carers.
2. Literature review
This based on health and transport literature
and review the links and impacts of urban
environment and community severance on
social interaction, leisure time physical activity
and quality of life amongst older people living
with dementia.
2.1. Impact of travel on social interaction:
Outdoor open spaces serve as a place for
social interaction among older people. Several
studies have confirmed the link between
attributes of outdoor spaces and the
formation of a social network among
neighbours. Longitudinal study has found that
frequent participation (daily-weekly) in social
activities is conducive to a decreased risk of
dementia (Wang, Karp, Winblad, & Fratiglioni,
2002). Another study in Ireland demonstrated
that people living in mixed-use, pedestrianoriented neighbourhoods, which provide
more opportunities for walking, and hence a
greater chance for neighbours to meet each
other outdoors, tend to know neighbours
better and engage in social activities more
often than those living in car-dependent
neighbourhoods (Leyden, 2003).
2.2. Impact of urban environment on
physical activity:
Getting outdoors offers physical, sociological
and psychological benefits for older people.
Physical inactivity is a major underlying cause
of disease and disability (WHO, 2003). Despite
abundant scientific evidence of the multiple
health benefits of physical activity, and
national and local level strategies to promote
an active lifestyle, the majority of older
people are not sufficiently active to maintain
good health. Some environmental attributes
help people carry out activities, while others
th art people s pla s or i te tio s. Studies
indicates that environmental determinants of
activity participation include: land-use
diversity, street pattern (connectivity), access
to shops, access to recreational facilities,
qualities of the pavement, aesthetics, safety
from traffic and crime are correlate with
physical activity (Frank, Schmid, Sallis,
Chapman, and Saelens, 2005; Humpel, Owen,
Leslie, 2002; Owen, Humpel, Leslie, Bauman,
Sallis, 2004; Saelens, Sallis, Frank, 2003).
2.3. Impact of urban environment on
quality of life:
Studies show older people living in low
density areas are more positive about their
quality of life than those in higher density
areas. Participants in villages and small towns
rated their quality of life highest and those in
major city/town centres lowest. Quality of life
was also rated higher in residential than in
mixed-use neighbourhoods. (Burton 2009).
Despite bad press, villages still seem to offer
many advantages. It may be possible to make
urban housing more attractive to older people
by increasing amount of greenery, some much
better than none, controlling non-motorised
traffic effectively, creating predominantly
residential areas that have facilities and
amenities scattered within them, using
distorted grid layouts, designing to encourage
social interaction. (Burton 2006 and Dempsey
2005).
2.4 Impact of community severance on
social contact:
No study found related community severance,
and its effects on behaviour (such as social
contacts, older people with dementia , older
people access to services), to short- or longterm mental or physical health outcomes,
except for one related study that found
reduced motor development in children not
allowed to play outdoors. (Hüttenmoser
1995). Appleyard a d Li tell s results, sho i g
a reduction in social contacts through the
deleterious effects of traffic (Appleyard D,
Lintell 1972, Appleyard D, Gerson 1981) have
ee li ked
ith Berk a a d Sy e s
(Berkman, Syme 1979) a d others findings
(Ellison CG. Race 1995) of increased mortality
in those with fewer social contacts. None of
these studies of morbidity or mortality have
examined reductions in social contacts as a
result of new roads or of increased speed or
volume of traffic on existing roads: the chain
of inference for the health effects of
community severance does not currently
extend to direct observation. It seems
inherently likely that the effects of community
severance do indeed impact on health, with
adverse health consequences of reduced
social contacts also occurring when this social
disruption is due to road traffic (Mindell.J
2011).
3. Research Methods
With the need to address the spiralling costs
of health care in the United States and around
the world, funders such as National Institutes
of Health (NHI) and Centres for Disease
Control and Prevention (CDC) and scientists
are placing more emphasis on translational
research. The logic of method in this research
suggests a comprehensive set of qualitative
and quantitative approaches, and employ
translational research model which can
generate the health and transport and
physical activity data. The data will be
analysing by NVivo.
3.1 Research Hypotheses
The hypotheses, based on the urban transport
and public health literature, were the people
with dementia living in
inaccessible
pedestrians and busy roads with high volume
of traffic avoid trip to local communities and
they are 1) less physically active; 2) less
socially interact within their community; 3)
feel unsafe, 4) have higher prevalence of
health problems linked to dementia, physical
inactivity and social networking than those
living in quite, car-free / pedestrian-friendly
places.
3.2 Translational Model and collecting
health and urban environment and
transport data
The translational model assess by developing
seven-steps
to
facilitate
stakeholder
participation in research while building the
capacity of the community to collaborate in
research with multi-and interdisciplinary
teams of social and medical science:
3.2.1 Partnership and Collaboration
Step.1) Creating a research ready network of
service which will collaborate with leading
health and transport research centres and
health organisation. This collaboration
include: the Design and Engineering and
Health Science and Social Care at Brunel
University with Inclusive Design Getting
Outdoor (I DGO), Dementia UK, Alzheimer
Society, Living Street, Sport for England and
Sustrans. The clinical memory trial will be
organised to collect data by design medical
trial and social intervention at primary care
and UK Clinical Research Network UKCRN to
evaluate the dementia amongst older people
in early stage.
3.2.2 Health and Physical Activity Data
Step.2) Recruiting older people with dementia
in early stage and their carers for interview to
assess parti ipa t s physical activity, life style,
health and interaction with outdoor
environment. Physical activity will be assessed
by employing International Physical Activity
Questionnaire (IPAQ). Parti ipa t s health a d
lifestyle will be assessed by employing
General Health Questionnaire (GHQ12) and
Warwick-Edinburgh Mental Well-Being Scale
(WEMWBS) which can identify predictors of
positive mental health in a convenience
sample of older people with dementia using a
cross-sectional design. Health data for
assessing individual older people with
dementia come from National Dementia and
Antipsychotic Prescribing Audit and Health and
Social Care Information Centre (HSCIC). Data
for measuring and mapping dementia coming
from Department of Health, National Health
Survey (NHS), Alzheimer Society, Dementia
UK.
3.2.3 Study Areas
Data to assess urban environment will be
collected from study areas sites within Older
a d Disa le Lo do er s Developments where
proposed by Great London Authorities in 2013
(GLA 2013). The locations for study identified
according to locations within inner and outer
London where dementia is higher than above
national average. Study areas Mapped by
dementia on map and selected because of
various locations within inner and outer
London borough where level of dementia are
above national average.
The selected study areas start from highest to
lowest percentage of dementia level in their
boroughs which are includes: Islington (63%),
Southwark (58%), Newham (58%), Camden
(56%), Tower Hamlet (54%), Westminster
(54%), Greenwich (52%), and Hackney (52%)
Barnet (52%), Kensington & Chelsea (51%),
Waltham Forest (51%), Lewisham (49%),
Richmond Upon Themes (49%), Hounslow
(46%), Lambeth (46%), Wandsworth (45%),
Enfield (44%), Haringey (43%), Havering
(39%), Hillingdon (37%), Harrow (33%)
(Department of Health 2014).
Furthermore, Barking & Dagenham had the
greatest decrease (-19.5 per cent) followed by
Tower Hamlets (-15.6 per cent). In all, 13
boroughs saw their older population shrink
over the period. In the remaining boroughs
population growth was greatest amongst
people 65 and over in Camden, where 12.7
per cent more people were recorded in 2011
than in 2001 (Great London Authority 2013).
3.2.4 Urban Environment Data
Urban environment data will be assessed by
urban design and street design appraisal and
Age-friendly environment approach (WHO,
2007), Dementia-friendly environment audit
which survey areas according to Familiar,
Legible, Distinctive, Accessible, Comfortable,
Safe built environment (Burton, 2006),
pedestrian-friendly approach, and Healthy
Urban Planning approach (Barton, 2006) to
evaluate the environmental features and its
impact on health and quality of life amongst
older people living with dementia and their
carers.
3.2.5 Transport and Community Severance
Data
Data to assess Community Severance,
Transport and Urban Environment come from
Department for Transport (DfT) traffic counts
data, such as total number of vehicles,
percentage of heavy goods vehicles (HGV) and
average speeds. It can also be assessed by the
characteristics of the road (such as number of
lanes and lane width) and by the number and
type of pedestrian crossings. It will assess the
change in the infrastructure and in traffic
levels over time. In addition to assess
community assessment the another concept
could be identified to measure three elements
from community severance which are: 1.
Existing of barriers to the mobility of
pedestrians; 2. Mobility needs of older people
with dementia and their carers living by; 3.
Characteristic of the environment and its
effect on social interaction amongst older
people with dementia (street volume, busy
road, clean and safe place). Further
framework which are includes: 1) the
suitability of surfaces for walking/cycling; 2)
street width, curb type and the presence of
vehicle parking; 3) traffic volume, speed and
the presence of management and control
devices; 4) the nature of traffic crossings and
crossing aids and verge widths; 5) street
design and the design and distance of
intersections and other access points; 6 issues
of personal safety such as lighting,
surveillance and path/lane obstruction; and 7)
aesthetic factors such as the presence of
trees, street maintenance, cleanliness and
pollution (Pikora 2003).
3.2.6 Collaborating Between University
Research Units and Service Agencies
Step.3) Developing a pool of investigators, in
resear h u it at U i ersity s Depart e t of
Health Science and Social Care and
Engineering Design to collaborate with service
agencies such as Dementia UK, Alzheimer
Society, etc.
Step.4) Developing pilot study programs on
linking community severance and dementiafriendly environment to physical activity such
as leisure time walking to utilities, green
spaces and connect investigators to research
opportunities involving community agencies.
Step.5) Developing and training investigators
and researchers who is willing to collaborate
within research areas about bridging
transport, health and dementia friendly
environment.
Step.6) Facilitating researcher-community
partner interaction through educational
events.
Step.7)
Engaging
researchers
and
practitioners on critical issues related to
ageing with dementia by developing a
research to practice consensus workshop
model.
4. Research Timeframe
The research will commence in April 2014 and
research completion will be in April 2017.
Year 1: Develop literature review; seek ethical
approval; gather transport, health and
physical activity data; simulate older adult
with dementia and starting interviewing older
people with dementia and their carers to
collect data on their mental health, leisure
time physical activity, social interaction
outdoor, community severance and their
sense of belonging in their community;
measure sample to validate dementia
estimates; describe and map dementia and
social change interview data.
Year 2: Gather urban environmental and
transport by site survey, urban design
appraisal and audits to collect community
severance, transport and urban environment
study areas;
organise social
data in
intervention and physical activity events to
measure before and after effect of social
interaction in outdoor environment; to better
understanding of the link between social
interaction and dementia and develop a
community severance and dementia friendly
model.
Year
3:
Predictive
analyses/evaluate
intervention impact; and employ NVivo to
analyses data.
5. Outcomes and Dissemination
The research will provide academic and policy
outputs and it will produce peer-reviewed
publications that ill uild o the super isor s
research on the relationships between
community severance, leisure time physical
activity and social interaction amongst older
people living with dementia and their carers.
The results will feed into Department for
Transport s a d Depart e t of Health s
ongoing review of the role of social change on
reducing the risk of dementia in the
community severance. The research findings
will have implications for urban design, street
design and spatial planning locally, nationally
and internationally.
This research project fills a gap in academic
knowledge, offering a multi-disciplinary
evidence-based approach to studying
dementia-friendly and community severance.
The research will be valuable to policy
makers, practitioners and local communities
and it focuses on reducing dementia in early
stage and making older people's lives
healthier and happier and to promotes
dementia friendly environment. The research
outcome will be disseminate across the many
users in the UK and abroad such as
practitioner and academic journals such as
Lo al Go er e t Chro i le , ur a studies ,
The La et , Pu Med , BMJ , Ashgate .
