Cities and the health
of the nation "Many would be surprised to learn that the greatest contribution to the health of the nation over the past 150 years was made not by doctors or hospitals but by local government. Our lack of appreciation of the role of our cities in establishing the health of the nation is largely due to the fact that so little has been written about it..."
Jessie Parfitt, 1986
How did urban conditions
affect health?
Manchester's River Irk in 1845
"...a narrow, coal-black, foul-smelling stream...in dry weather, a long string of the most disgusting, blackish-green slime pools are left standing...from the depths of which bubbles of miasmatic gas constantly arise and give forth a stench unendurable even on the bridge forty or fifty feet above the surface of the stream."
Frederick Engels
Manchester, 1859
"Earth and air seem impregnated with fog and soot. The factories extend their flanks of fouler brick one after another, bare, with shutterless windows, like economical and colossal prisons...Through half-open windows we could see wretched rooms at ground level, or often below the damp earth's surface. Masses of livid children, dirty and flabby of flesh, crowd each threshold and breathe the vile air of the street, less vile than that within...“
Hipployte Taine
The health impact
Life expectancy for mechanics and labourers in Manchester in 1842 was 17 years
How did health affect urban
affairs?
Health and urban affairs
Renaissance Italy’s City States had Boards of Health
1843/4 – Health in Towns Commission and Association, UK
1875 – The ‘Great’ Public Health Act “Hygeia: A City of Health”
1890s – Garden Cities
Health and urban planning
Waste management solid liquid
Water treatment Housing conditions Zoning Various City Departments Urban planning in Canada
1912-21 Canada’s Commission on Conservation “The City Healthy” - 1915 Thomas Adams and urban planning –
1914 - 1917 1915 – Toronto is “The healthiest of
large cities” - (MacLean’s Magazine) 1929 –1938 – Milwaukee “The
Healthiest City”, US Chamber of Commerce’s Inter-Chamber Health Conservation Contest

The built environment
and climate change urban sprawl energy-inefficient buildings energy-inefficient technologies vehicle motors, pumps, lights etc NB - “pumps are the biggest users of
motors, motors use 3/5 of the world’s electricity” - Amory Lovins, RMI
Climate change and health
Direct effects more frequent heat
events (which in urban areas will exacerbate air pollution)
more frequent and severe extreme weather events, causing deaths and injuries
flooding
Indirect effects a wider distribution
of insect disease vectors (particularly mosquitos)
disruption of ecosystems, particularly agro-ecosystems and oceanic ecosystems
Eco-refugees, conflict over resources

Urban design and traffic injuries
1 point increase in ‘sprawl index’ over 448 US metropolitan counties= 1.5% in traffic fatality rate= 10x higher in most v least sprawling
Walking and biking fatality rates are higher in sprawling counties BUT lower in counties - and countries -
where walking & biking is common Frumkin, Frank and Jackson,
2004
Traffic deaths v violent
deaths by strangerRisk of dying in 15 medium and large US metropolitan areas, over 15 years
Traffic fatality rate much higher in suburbs than risk of death by a stranger in the central city and this would likely be even more
true in Canada so are we really safer moving to
the suburbs?Lucy, cited in Frumkin, Frank and Jackson,
2004
Physical Activity and
Health Status “One of the strongest theories
(to explain the radical changes in the health status of Americans) is the significant decline in activity levels . . . today compared with levels from 50 or 100 years ago.” Jackson and Kochtitzky in Creating a
Healthy Environment (Sprawl Watch Clearinghouse, 2001)
How (In)Active are Canadians?
Only 11% do aerobic activity sufficient to gain cardiovascular benefit (30 minutes at 50% of individual capacity, 3-4 x/week)
33% of Ontarians are inactive (energy expenditure <1.5 kcal/kg/day)
Economic Burden of Physical Inactivity in Canada
The costs attributed to physical inactivity for just seven conditions for which it is a known contributor
(coronary artery disease, stroke, hypertension, colon cancer, breast cancer, type 2 diabetes and osteoporosis)
2.5 percent of direct health care costs
10.3 percent of deaths NB Does not include indirect costs e.g. lost
productivity and long or short-term disability.
Why Are We Inactive?
Sedentary jobs Inactive transport
commuting, shopping, etc Sedentary leisure/housework
TV, internet, etc powered vehicles (e.g., skidoo,
seadoo, ATV, etc.) power tools (kitchen, garden,
repairs, etc.)
Deterrents to cycling/walking
Safety from other road traffic Barriers due to road system Unpleasant exhaust fumes Lack of secure facilities for
biker Inconvenience eg., sweat,
fatigue, painBased on Morton, 2000 and
WHO Centre for Urban Health
Benefits of Physically Active Commuting to
Work Among 68 inactive middle
aged men and women in a RCT, 1 hour daily PACW for 10 weeks led to increases in
VO2 max 4-5% Max treadmill time 10.3% HDL cholesterol 5%
Source: Vuori, Oja and Paronen, 1994
The Benefits of Walking
“Imagine if half the people in Canada who live within walking distance of their work left their cars at home. Their efforts would save approximately 22 million litres of gasoline per year!”
Go for Green!
Costs of Transport/ Benefits of Walking
Total external costs of transport, 17 European countries, 1995 = 7.8% of GDP
If all sedentary adults in the US walked regularly, estimated savings could be $US 4.3-5.6 billion/yearSource: WHO Europe, Centre for Urban Health
The Health Benefits
of Active LivingReductions in Coronary heart
disease Cancer (colon,
breast) Obesity (leads
to diabetes) Osteoporosis
Arthritis Depression/ anxiety/stress
Cognitive impairment
Injuries related to MVAs/other power uses
Benefits of Parks and Recreation
Personale.g. stress management, self-esteem, health
Sociale.g. promotes involvement and interaction
Economice.g.productive work force, reduced vandalism
Environmentale.g.improved environmental health and awareness
Commuting time & social capital
A 1 hour commute each way = a 40 hour work week every 4 weeks, or
11 - 12 work weeks a year This is a large loss of family
and community time = a large loss of social capital

Communities
Urban Design for Health

A Medical Miracle?“At its best, Smart Growth is like a
medicine that treats a multitude of diseases - protecting respiratory health, improving cardiovascular health, preventing cancer, avoiding traumatic injuries and fatalities, controlling depression and anxiety, improving wellbeing. In the medical world, such an intervention would be miraculous. In the worlds of land use and transportation, it is a thrilling, and attainable, opportunity.”
Frumkin, Frank and Jackson, 2004
Encouraging physical activity
Municipal governmentUrban planning/design Higher density Mixed land use Bike/walk friendly
Accessible and attractive paths, trails Safety Transit
Parks and Recreation Services ‘Active living’ programs Services for those with low incomes
Encouraging physical activity/2
School boards Curriculum
Make exercise fun and normal ‘Walking school bus’Businesses Encourage ‘active commuting’
Discourage free parking, esp downtown
Support active living (e.g stairs) Adopt & maintain trails
Encouraging physical activity/3
Community agencies Provide active recreation
services Encourage/support ‘walking
clubs’ etcCitizens Become active Adopt & maintain trails Turn off TV and get out!
Ditto for your kids!
It takes a whole community to raise healthy
people!
Municipal governments:
Policy and environments
Use the public health provisions of the Community Charter, e.g.
Smoking by-laws Public works (drinking water,
sewage, waste disposal) Traffic and roads (safety) Housing quality (health, safety)
and more
Public transit (air quality, safety, physical activity)
Parks and Rec (physical activity, mental health, environment/ habitat)
Planning/Land use (air quality, physical activity, urban food systems)
other examples?
Some emerging developments

A global movement
In every WHO Region EURO - more than 600 Healthy Cities
programmes WPRO - approximately 170 cities AMRO - estimated to be more than 300. EMRO - Many countries have established
national Healthy Cities networks - Healthy village programmes are now very popular in the Region
SEARO - ongoing Healthy Cities programmes exist in all Member States
AFRO - a number of cities have begun Healthy Cities activities.
Ontario Healthy Communities Coalition,
(Sept 2004 Update) Established in the late 1980s,
and currently involves 166 active healthy community groups and coalitions within 98 locations.
Mission - “to work with the diverse communities of Ontario to strengthen their social, environmental, and economic wellbeing”.
Villes et Villages en Sante (July 2002 update) There are currently some 150
municipalities that are members, covering some 50 percent of the population; most of Quebec’s big municipalities and many of its middle sized municipalities are members.
Regular membership, with voting privileges, is restricted to municipalities and is based on the passage of an official resolution by the Municipal Council.
Lessons from the Quebec and Ontario
experience Both organizations are based on
the membership of communities, who constitute the majority of the Board of Directors of both organizations.
Neither organization provides direct funding to communities, but instead provides a wide range of education, training and other supportive and capacity-building services and activities.
In Ontario, a key feature is that two-thirds of the staff are community animators based all around the province and providing services within defined regions.
Both organizations rely on close collaboration and partnerships with other provincial organizations and networks that have shared interests.
Both organizations are heavily dependent on government funding, but at arms length (through the Institute of Public Health in Quebec, as a non-profit charity in Ontario).
In neither case do provincial governments have members on the Board of Directors
A healthy city . . . " . . . is one that is continually
creating and improving those physical and social environments and expanding those community resources that enable people to mutually support each other in performing all the functions of life and in developing to their maximum potential."
Hancock and Duhl, 1986
Healthy Communities
Applies the concepts of health promotion in the settings where people live, learn work and play Homes Schools Workplaces Health care facilities Communities
Healthy Communities
approach Community involvement
