Population and demographic
changes
Human Determinants of Transitions
• technological change
• alterations in the environment
• alterations in food type, availability,
production, preparation, and consumption
• alterations in patterns of energy
expenditure
• interplay of environmental factors and the
genetic pool of a community
Epistemological Framework of
Epidemiological Transitions
MULTIPLE EPIDEMIOLOGIC
TRANSITIONS
• recent resurgence of infectious disease
mortality marks a third epidemiologic
transition
• characterized by newly emerging, reemerging, and antibiotic resistant
pathogens in the context of an accelerated
globalization of human disease ecologies
Human Determinants of Transitions
REDUX

• alterations in the environment
• alterations in food type, availability,
production, preparation, and consumption
• alterations in patterns of energy
expenditure
• interplay of environmental factors and the
genetic pool of a community
• Social inequality? Where is it?
“SOCIAL FORCES AND
PROCESSES EMBODIED AS
BIOLOGICAL EVENTS”
THE CRITICAL PERSPECTIVE
• Paul Farmer:
• “Inequality itself constitutes our modern
plague – inequality is a pathogenic force”
• “Social inequalities often determine both
the distribution of modern plagues and
clinical outcomes among the afflicted”
Life Expectancy & Ethnicity in the
US
First Nations people and Inuit face some serious
health-related challenges, such as high rates of
chronic and contagious diseases and shorter life
expectancy.
Compared to the general Canadian population,
•Heart disease is 1.5 times higher;
•Type 2 diabetes is 3 to 5 times higher among First Nations
people and rates are increasing among the Inuit; and
•Tuberculosis infection rates are 8 to 10 times higher.
•15 per cent of new HIV and AIDS infections occur in
Aboriginal people.
First nations and TB
• The tuberculosis rate in the First Nations
was 8 to 10 times that of the entire
Canadian population in 1999.
Overcrowded housing is associated with
an increased risk of tuberculosis in a
community

Bourdieu: 3 types of capital
• Economic capital: command over economic
resources (cash, assets).
• Social capital: resources based on group
membership, relationships, networks of influence
and support.
• Cultural capital: forms of knowledge; skill;
education; any advantages a person has which
give them a higher status in society, including high
expectations.
– E.g. Parents provide children with cultural capital, the
attitudes and knowledge that makes the educational
system a comfortable familiar place in which they can
succeed easily.
Definitions of Social Capital
• In contrast to classical and neoclassical economic theory
– assumes society is made up of the sum of persons acting individually to
achieve non-collective goals
• Social capital inheres the structure of relationships between
persons and among persons.
– the institutions, relationships and norms that shape the quality and
quantity of a society's social interactions.
• Social capital has a material base as well as a moral base.
• People have different amounts of social capital
– depending on the actual or potential resources
– depending upon the size of the network to which they are linked
– depending on the amount of economic and cultural capital the members
of that network have.
• Social capital is never independent of the other forms of capital
Social Capital & Health in Canada
With regard to social capital, studies increasingly
show that communities supported by a substantial
stock of social capital have better economic and
social performance (Putnam, 2000).
Better health, health conditions, and health care.
Canada, Health, & Inequalities
Social & Cultural Capital:
Non-Medical Determinants of Health
• Compared with the Canadian population in 1996,
the First Nations population (on and off reserves)
rated lower on all educational attainment.
• Among First Nations, the 1996 labour participation
rate was 59% and the employment rate was 43%.
– Rates for Canada as a whole were 68% and 62%,
respectively.
• First Nations unemployment rate was twice the
Canadian rate in 1996.
Non-Medical Determinants of Health
• In First Nations communities only 56.9% of homes
were considered adequate in 1999--00.
• 33.6% of First Nations communities had at least
90% of their homes connected to a community
sewage disposal system.
• In 1999, 65 First Nations and Inuit communities
were under a boil water advisory for varying lengths
of time--an average of 183 days of boil water
advisories per affected community.
• Many communicable diseases such as giardiasis
and shigellosis (both acute infectious diseases
characterized by diarrhea, fever and nausea) can
be traced to poor water quality
Cultural Capital & Health
World-Wide Health Inequalities
WORLD SYSTEMS
World Systems (I. Wallerstein)
• A world-system is a social system
– one that has boundaries, structures, member groups,
rules of legitimation, and coherence.
• made up of the conflicting forces which hold it
together by tension and tear it apart as each
group seeks eternally to remold it to its
advantage.
• a life-span over which its characteristics change
in some respects and remain stable in others.
• its structures -- at different times strong or weak
in terms of the internal logic of its functioning.
