Patients and the public need to be able to understand health materials in order to become and stay healthy. Researchers from King's College London and Keele University looked at the literacy and numeracy complexity of health materials in common circulation and compared this to the skills of the English adult working-age population. The study found that the materials were written at too complex a level for 43% of working-age adults (16-65 years old): this figure rises to 61% if the health information includes numeracy. The Health Literacy Group has worked with key partners, including NHS England, to develop an action plan to address this. The research publication is cited in a policy briefing from the Community, Health and Learning Foundation and the full publication is is soon to be published in the British Journal of General Practice: please contact the lead author Gill.Rowlands@kcl.ac.uk for further information. The executive summary of the action plan is also available here.
