Putting the Population into Population Health

   Population health is challenging health promotion as the dominant discourse
in Canadian health policy. Its influence is seen in the renaming of government
branches and departments and the numerous documents addressing population
health.1 The impetus for this challenge has come from work by the Population
Health Group of the Canadian Institute for Advanced Research (CIAR), an
international group consisting primarily of health economists and
epidemiologists.1,2 This commentary examines the implications for health
research and action of the CIAR vision of health as presented in the key
document, Why are Some People Healthy and Others Not?3

Population Health is Firmly Rooted in the Epidemiological Tradition
   The CIAR definition of health owes nothing to WHO concepts: "For the most
part we simply assume that health is the absence of illness."4, p.24 Similarly,
the CIAR inquiry into determinants of health emphasizes exposures to
environmental stimuli, identification of cause and effect relationships, and
methods limited to experimental designs and quantitative data. It has been
argued that:

        There is a growing realization that traditional logical positivist
        approaches to health promotion research and evaluation no longer
        provide the right questions (or indeed answers) for many health
        promotion interventions.5,p.1

In this critique, biomedical approaches are unable to consider lived
experiences of people, a form of knowledge essential to understanding the
origins of health and health-related behaviours.6-8

Population Health Lacks An Explicit Values Base
   All health-related research and practice involve values.9,10 This is not
problematic; what is problematic is not making explicit the values underlying
an approach.11  The CIAR approach ignores issues of participation, equity,
community, collaboration, and social justice.12 The result is a reliance on
large-scale data collection surveys that do little to enable or empower
individuals. Indeed, biomedical approaches may reflect conservative values that
serve the status quo.9

Population Health Neglects Political and Sociological Issues
   The CIAR vision offers no theory of society.13 It neglects how health
determinants are created and maintained by powerful economic and social forces.
Analysis of the causes of economic inequality and poverty, for example, are not
high on the population health agenda..14 An approach that ignores these forces
is unlikely to be useful for identifying and acting upon the inequities in
health seen among Canadians.

Population Health Leads to Context Stripping
   Context stripping occurs when the health of individuals is considered
removed from its community and societal context. Within the health field,
context stripping occurs when studies attempt to identify general determinants
of health across populations. To illustrate, analysis of how societal and
community structures influence individuals' sense of control and well-being
gives way to study of personal coping devices and the biological mechanisms by
which stressors become translated into illness and disease. Critical analysis
of society give way to studies focused on individual-level variables.
 Population Health Provides a Model of Research, Not of Social Change
   CIAR does not provide a model of change, and there is a hesitancy among its
adherents to suggest health-enhancing policy responses: In 1994, Evans wrote:
We cannot offer a detailed prescription of what is to be done,4,p.24 a
sentiment he repeated five years later.15 Unless research aims to influence,
rather than merely describe the determinants of health, it is unlikely to
improve health. In contrast, the health promotion tradition emphasizes
strengthening communities, building supportive environments and promoting
healthy public policy as means of improving health.16,17

Population Health Minimizes the Importance of Poverty
   CIAR writings tend to minimize the problem of poverty -- its causes,
consequences, and solutions. In Why Are Some People Healthy and Others Not?,
Evans stated: Indeed, a focus on poverty can block progress in understanding,
because it can be dismissive of further questions.4,p.5 Poverty is one of the
strongest determinants of health,18-21 but from the CIAR perspective, focus on
poverty -- and working to alleviate it -- distracts from "further questions."
Studying and improving the lives of those in poverty should be a priority for
health researchers.

Population Health Exhibits a Top-Down Emphasis on Expert Knowledge
   The CIAR vision of health is not one of working with people in communities
to understand and influence the determinants of health.22 The CIAR denial of
the validity of alternate forms of knowledge, the importance of community
participation, and the value of enabling and empowering people has been ignored
as "population health" has been embraced. In reality, traditional biomedical
approaches to health research can work against health.23

Putting the Population Back into Population Health
   Efforts to improve health should be based on clear statements of values and
principles. The validity of various forms of knowledge must be accepted through
a commitment to pluralism in methods. Analysis of determinants should occur at
societal, community, and individual levels, and the political dimension of
health is acknowledged. Finally, providing information for change is a key
element in health research.
  These ideas are consistent with developments in health promotion. Such ideas
have seen application in innovative and community-based Canadian efforts such
as the Pathways to Building Healthy Communities in Eastern Nova Scotia and the
Community Quality of Life projects in Toronto.24,25 There, community members
identify and act upon determinants of health by drawing upon their experiences
and developing critical understandings of how societies operate. Armed with
these understandings, they identify policy issues that become the basis of
efforts to influence government actions.26
   Such approaches are guided by values of equity, participation, and social
justice; concepts absent in CIAR thinking.27 Without such commitments, the CIAR
vision of population health is unlikely to enhance the health of Canadians. It
certainly will not enhance the health of Canadians most in need; those living
in poverty. Before population health replaces health promotion as health
policy, serious thought must be given to the implications of such a shift on
efforts to maintain and enhance the health of Canadians.28
