The purpose of this study was to clarify the current situation of health literacy (HL) and related factors among the elderly living in urban Japan. Anonymous, self-administered questionnaires were distributed to members of seniors’ clubs in an urban area in Japan. The survey contents included basic characteristics, sources of health information, and self-perceived health. In addition, participants were asked to complete the 47-item European Health Literacy Survey Questionnaire (HLS-EU-Q47 Japanese-language version).
Descriptive analysis was performed and compared according to three HL domains and four HL competencies after calculating the HL standardization index. Of the 561 questionnaires distributed, 381 responses were received; of these, 368 were included in the analysis. The participants’ mean age was 76.9 years old (range, 65−95 years). Nearly all the participants (97.0%) answered that they were “very interested in health” or “somewhat interested in health.” Television was the most common source of health information, followed by friends and family, health care professionals, newspapers, community papers, and the Internet.
Regarding the HL standardization index, The mean (SD) total HL was 27.5 (8.8), which was considered “slightly insufficient.” In terms of competency, “understanding HL” was the highest, followed by “obtaining HL” and “evaluating HL.” The participants in this study were basically very interested in health, and it was likely that they had acquired HL through having many opportunities to see health information on disease prevention. However, it became clear that they had some difficulty accessing needed health information by themselves as well as evaluating the necessity and reliability of the information.
