Health Literacy of People with and without Disabilities and Chronic Diseases in Germany: Results of the Study "German Health Update" 2014/2015-EHIS

Background People with disabilities and chronic diseases represent a population group in vulnerable circumstances, and often have difficulty finding, understanding, assessing, and applying health information. The aim of this study was to examine the health literacy of people doubly burdened with both disabilities and chronic diseases in comparison to two other groups, namely people with either disabilities or chronic diseases and people without impairment. Material and methods Our data is based on the representative survey "German Health Update" 2014/2015-EHIS. The sample consists of n=21,647 people, including 2,875 (13.3%) people with disabilities and chronic diseases, 7,598 people (35.1%) with disability or chronic diseases and 11,174 (51.6%) people without impairment. Health literacy was measured using the short form of the questionnaire of the European Health Literacy Survey (HLS-EU-Q16). Uni, bi- and multivariate analyses were conducted. Results 43.7% of respondents with both disabilities and chronic diseases had quite a lot difficulties in dealing with health information in comparison to people with disabilities or chronic diseases (37.7%) or those with no impairment (33.0%). People with double burdens had a 1.22-fold (CI: 1.10-1.35; p<0.001) and people with a single burden had a 1.08-fold (CI: 1.01-1.16; p=0.031) increased likelihood to find it difficult or very difficult to find, understand, evaluate and apply health-related information compared to people without impairment. Conclusion The results show a gradient to the disadvantage of people with disabilities and/or chronic diseases. Health literacy among people with disabilities and/or chronic diseases should be adequately promoted in order to support their health, their participation as well as the quality and efficiency of and the reduction of barriers to access health care.
