Inequalities in health: what health systems can and cannot do

Abstract

Health promotion activities are actively encouraged in most countries, including the UK. Meanwhile many health care providers and health experts are becoming increasingly concerned about the growing evidence of significant health inequalities between social groups in the UK, and in particular the strong association between relative deprivation and poor health. In 1995, a report for the British government entitled 'Variations in health: what can the Department of Health and the NHS do?', identified the need for the Department of Health and the NHS to play a key role in coordinating and implementing public health programmes intended to reduce inequalities in health. Examination of existing evidence on the effectiveness of health promotion and prevention programmes designed to improve the health status of the most vulnerable groups in society reveals very little evidence to support current enthusiasm for adopting public health strategies in order to reduce variations in health status between the affluent and the poor. Alternative and potentially more effective health care responses to inequalities in health status need to be considered.
