Social determinants of health

The Commission on Social Determinants of Health - what, why and how?

What is the Commission on Social Determinants of Health?

The Commission on Social Determinants of Health (CSDH) was a global network of policy makers, researchers and civil society organizations brought together by the World Health Organization (WHO) to give support in tackling the social causes of poor health and avoidable health inequalities (health inequities).

When and why was it created?

The CSDH was set up by Dr JW Lee, the former Director-General of WHO in March 2005 to bring together evidence on what can be done to achieve better and more fairly distributed health worldwide, and to promote a global movement to achieve this.

What was it expected to do?

The CSDH had a three year directive to gather and review evidence on what needs to be done to reduce health inequalities within and between countries and to report its recommendations for action to the Director-General of WHO. Building partnerships with countries committed to comprehensive, cross-government action to tackle health inequalities was integral to this. Experts were brought together to gather evidence, and civil society organizations also participated in the process.

Who were its members?

The CSDH was led by a remarkable group of Commissioners with wide experience in politics, academia and advocacy:

How did it function?

The Commission was a truly global process, bringing together hundreds of researchers and practitioners from universities and research institutions, government ministries, and international and civil society organizations.

‘Knowledge networks’, including academics and practitioners from around the world, collected evidence on policies and interventions to improve health and reduce health inequities across a number of areas including: early child development, employment conditions, globalization, women and gender equity, urban settings, social exclusion, health systems, measurement, and priority public health conditions.

The Commission built further evidence-gathering partnerships through two regional networks (the Nordic and Asian networks) and with researchers in additional key areas, such as ageing, indigenous peoples, food and nutrition, violence and conflict, and the environment.

Partnerships with a number of countries committed to tackling health inequities were established. Brazil, Canada, Chile, Iran, Kenya, Mozambique, Sri Lanka, Sweden, and the United Kingdom each became a Commission ‘country partner’, and made a commitment to progress on the social determinants of health to improve health equity. As the work of the Commission gained momentum, other supportive countries added both to the technical work on tackling social determinants for health equity (e.g. Norway) and to sharing experiences and advice on improving policy coherence in this field (e.g. Thailand).

Representatives of civil society groups in Africa, Asia, the Americas, and Europe contributed to the Commission’s work. Members of these groups were engaged in the Commission’s knowledge-gathering processes. They helped to shape the Commission’s thinking and will be active partners for change in the future.

The reports produced by the knowledge networks and all other background papers and reports, including reports from the country and civil society work streams, are available on the publications pages:

What was the thinking behind the Commission?

The Commission demonstrated that health inequities are the result of a complex system operating at global, national and local levels.

The global context affects how societies prosper through its impact on international relations and domestic norms and policies. These in turn shape the way society, at national and local level, organizes its affairs, giving rise to forms of social position and hierarchy. Where a person is in the social hierarchy affects the conditions in which they grow, learn, live, work and age, their vulnerability to ill health and the consequences of ill health.

To decrease the health inequality between and within countries, it is necessary to look beyond the immediate causes of disease. The Commission focused on the 'causes of the causes' - the social factors which determine how people grow, live, work and age. The underlying determinants of health inequities are interconnected and therefore, they must be addressed through comprehensive and integrated policies, responsive to the specific context of each country and region.

What was its approach to evidence?

Dedicated Knowledge Networks covering a number of themes reviewed the evidence and reported their findings to the Commission.

The Commission took a broad approach to evidence. Traditional hierarchies of evidence (which put randomised controlled trials and laboratory experiments at the top) generally do not work for research on the social determinants of health. The evidence needs to be judged on fitness for purpose - that is, does it convincingly answer the question asked? The Commission’s evidence comes from observational studies (including natural experiments and cross-country studies), case studies, and field visits, from expert and lay knowledge, and from community intervention trials where available.
