Social Determinants of Health (September 30, 2002)
Overview of Social Determinants of Health
Dennis Raphael School of Health Policy and Management York University, Toronto, Canada
Poor conditions lead to poorer health. An unhealthy material environment and unhealthy behaviours have direct harmful effects, but the worries and insecurities of daily life and the lack of supportive environments also have an influence.

Social Determinants of Health: Literary Perspectives
We know what makes us ill. When we are ill we are told That it’s you who will heal us. When we come to you Our rags are torn off us And you listen all over our naked body. As to the cause of our illness One glance at our rags would Tell you more. It is the same cause that wears out Our bodies and our clothes.
-- Bertolt Brecht, A Worker’s Speech to a Doctor, 1938.
Social Determinants of Health: Academic Perspectives
It is one of the greatest of contemporary social injustices that people who live in the most disadvantaged circumstances have more illnesses, more disability and shorter lives than those who are more affluent.
-- Benzeval, Judge, & Whitehead, 1995, p.xxi, Tackling Inequalities in Health: An Agenda for Action .
Canadian Government Statements on Social Determinants of Health I
All policies which have a direct bearing on health need to be coordinated. The list is long and includes, among others, income security, employment, education, housing, business, agriculture, transportation, justice and technology. -- Achieving Health For All: A Framework for
Health Promotion, J. Epp. Ottawa: Health and Welfare Canada, 1986.
Canadian Government Statements on Social Determinants of Health II There is strong evidence indicating that factors outside the health care system significantly affect health. These “determinants of health” include income and social status, social support networks, education, employment and working conditions, physical environments, social environments, biology and genetic endowment, personal health practices and coping skills, healthy child development, health services, gender and culture.

Promotion and Programs Branch Staff. Ottawa: Health Canada, 1998.
Canadian Government Statements on Social Determinants of Health III
In the case of poverty, unemployment, stress, and violence, the influence on health is direct, negative and often shocking for a country as wealthy and as highly regarded as Canada.
-- The Statistical Report on the Health of Canadians. Ottawa: Health Canada, 1998.

It was found that those living in lower income areas were much more likely to develop coronary heart disease than those in well-off neighbourhoods. These effects remained strong even after controlling for tobacco use, level of physical activity, presence of hypertension or diabetes, level of cholesterol, and body mass index.
