An umbrella review of the effects of public health policies in high income countries has been published. It suggests some interventions that policy makers might use to reduce health inequalities, but the transferability between high-income countries remains unclear.
Results of the assessments of polices were mixed: some were shown to reduce health inequalities (e.g. food subsidy programmes, immunisations), while others have no effect and some interventions appear to increase inequalities (e.g. 20 mph and low emission zones).
