Time to act on social determinants of health
Where we live, where we work, our education, our early childhood, our social power, our access to land and water: all these social determinants and many more, affect our health. This issue of Health Exchange focuses on the social determinants of health, what they mean for health workers and how we put this approach into practice. There are articles from a range of perspectives: the role of government in Sri Lanka, an NGO working at the grassroots in Kenya, an indigenous person’s view of holistic health in Nicaragua, early childhood development projects in Brazil, and community action in Sri Lanka. There is also an article discussing the work of the World Health Organization’s Commission on the Social Determinants of Health, which has spearheaded efforts to bring the approach to the forefront. Another contributor shares experience from a housing project in India’s urban slums.
We have added a new section to this edition of Health Exchange – Innovations in Health Research – which focuses on innovative research with practical applications to help solve some of the world’s most pressing health problems.
There are nine articles in the print edition of Health Exchange but we have more online. Additional articles in the online version include early childhood development in Chile, the process of community led total sanitation, and a longer version of Rene Loewenson’s article on social empowerment as a determinant of health. There is a report from the World Health Assembly in Geneva on the recently passed resolution on social determinants of health and podcast interviews with Abdul Sattar Yoosuf and Kumanan Rasanathan, both of the World Health Organization.
Health Exchange online is interactive so please feel free to add your comments and feedback.
We also keep adding new material to the online version; both to the current topic and to previous topics; for example, there are brand new articles about women and health. If you would like to contribute an article to any of the topics we cover please get in touch. The next issue, in Autumn 2009, will be about health workers and the health work force.

Social determinants of health: time to act for health equity
Social determinants have extremely powerful influences on health. The World Health Organization’s Commission on the Social Determinants of Health worked for several years to explore the global situation further. Ruth Bell, from University College London, talks about the work of the Commission and urges health workers at community level to call for action.
Health workers, more than anyone else, see the dramatic effects of the social determinants of health in their daily work. There is no biological reason why a girl born in Zambia should have a life expectancy of 43 years, while her counterpart born in Japan should have a life expectancy twice as long at 86 years. In a deprived part of Glasgow, Scotland life expectancy for men, at 54 years, is less than the average for men in India (62 years) where nearly 80 per cent of the population live on less than two dollars a day. Social determinants are linked to ill health and premature death witnessed by health workers wherever they are around the world.
The social determinants of health are the conditions in which people are born, grow, live, work and age, and the structural drivers of those conditions, that is the distribution of power, money and resources. The Commission on Social Determinants of Health (CSDH) was set up by the World Health Organization in 2005 to support action on the social determinants of health to improve overall population health, improve the distribution of health, and to reduce disadvantage due to poor health. It published its Final Report and recommendations in 2008.
The CSDH’s aim was to stimulate action to reduce the health inequalities that exist between countries and within countries. According to the CSDH, in situations where health inequalities are preventable and avoidable, but are not avoided, they are inequitable, and taking action to reduce them is a matter of social justice.
The CSDH recommendations are based on three principles for action:
1. Improve the conditions of daily life – the circumstances in which people are born, grow, live, work, and age.
2. Tackle the inequitable distribution of power, money, and resources – the structural drivers of those conditions of daily life – globally, nationally, and locally.
3. Measure the problem, evaluate action, expand the knowledge base, develop a workforce that is trained in the social determinants of health, and raise public awareness
about the social determinants of health.
What kind of action has the CSDH stimulated and what will be the effects on health?
It can seem a long way from a high-level policy review to action that makes a difference on the ground. Three points are important here. First, health inequities are associated with social inequalities. Health outcomes are linked to position in social hierarchies, described by income, occupation and education, by ethnic group or by gender and to geographic location, for example, rural or urban. In particular, poor health outcomes are likely where social inequalities intersect, for example, for children of women with no education in poor households in rural areas. Studies in low and middle income countries in Africa and Asia show a stepwise increase in under-five mortality across households by wealth, with children from the poorest fifth of households more likely to die before their fifth birthday than the next poorest and so on across the distribution. This pattern is seen for a number of health outcomes and is known as the social gradient in health, meaning that health outcomes are associated with people’s position in the social hierarchy. The social gradient has important implications for policy as it means that policies and programmes must not only target the worst off in society, but must also address the conditions of the whole of society in order to tackle the gradient in health.
Second, and crucial to the social determinants of health approach, is that where differential health outcomes are linked to social inequalities, then action to improve health outcomes must include action to reduce social inequalities. Seen in this light, every sector is, in effect, a health sector, because every sector, including finance, business, agriculture, trade, energy, education, employment, and welfare, impacts on health and health equity.
Thirdly, action needs to happen at global, national and local levels. The national level policy environment needs to empower grass roots community participation in identifying what needs to happen, in developing interventions and programmes and in evaluating their effects. The Commission’s report is optimistic. The global movement for health equity is growing. Progress may be patchy but progress can be made and the report contains examples of successful action including work in Sri Lanka and India (see articles in this issue of Health Exchange). But there needs to be more innovation and more evaluation so that promising approaches can be developed and extended to reach more people. Health workers at the heart of communities have a pivotal role to play in raising awareness and calling for action on social determinants and in the process of developing and evaluating action at local and national level.
