Socioeconomic inequalities in health have been studied extensively in the past decades. In all high-income countries with available data, mortality and morbidity rates are higher among those in less advantaged socioeconomic positions, and as a result differences in health expectancy between socioeconomic groups typically amount to 10 years or more. Good progress has been made in unravelling the determinants of health inequalities, and a number of specific determinants (particularly material, psychosocial, and lifestyle factors) have been identified which contribute to explaining health inequalities in many high-income countries. Although further research is necessary, our understanding of what causes health inequalities has progressed to a stage where rational approaches to reduce health inequalities are becoming feasible. Evidence of a reduction of health inequalities via interventions and policies based on the underlying causes remains scarce, and point to a need to increase efforts.
