  5. Poverty and Health: Mechanisms Poverty can affect health in a number of ways: • income provides the prerequisites for health, such as shelter, food, warmth, and the ability to participate in society; • living in poverty can cause stress and anxiety which can damage people’s health; • low income limits peoples’ choices and militates against desirable changes in behaviour. - Benzeval, Judge, & Whitehead, 1995, p.xxi, Tackling Inequalities in Health: An Agenda for Action.

Critical Periods of the Life Course • Fetal development • Birth • Nutrition, growth and health in adulthood • Educational Career • Leaving parental home • Entering labour market • Establishing social and sexual relationships • Job loss or insecurity • Parenthood • Episodes of illness • Labour market exit • Chronic sickness • Loss of full independence --Shaw et al., The Widening Gap, 1999, p. 106.

  11. Economic Inequality: Explanations • Economically unequal societies have greater levels of poverty (individual poverty explanation) • Economically unequal societies have greater hierarchy and weaker social cohesion (social comparison explanation) • Economic unequal societies provide fewer social safety nets and social investment (neo-materialist explanation)

  12. Economic Inequality and Health • What matters in determining mortality and health in a society is less the overall wealth of that society and more how evenly wealth is distributed. The more equally wealth is distributed the better the health of that society. • Editorial: The big idea. British Medical Journal, April 20, 1996, 312, 985.

  13. Economic Inequality and Health • Inequality may make people miserable long before it kills them. • Editorial: Income inequality and mortality: Why are they related? British Medical Journal, April 20, 1996, 312, 987-988.

  14. Neo-Materialist Viewpoint I • Income inequality has generally been associated with differences in health • A psychosocial interpretation of health inequalities, in terms of perceptions of relative disadvantage and the psychological consequences of inequality, raises several conceptual and empirical problems • Income inequality is accompanied by many differences in conditions of life at the individual and population levels, which may adversely influence health • - Lynch et al., BMJ, 2000

  15. Neo-Materialist Viewpoint II • Interpretation of links between income inequality and health must begin with the structural causes of inequalities, and not just focus on perceptions of that inequality • Reducing health inequalities and improving public health in the 21st century requires strategic investment in neo-material conditions via more equitable distribution of public and private resources • - Lynch et al., BMJ, 2000
