Association Between Health Literacy and Understanding of Doctors' Explanations: The Yamagata Study.

Background: In Japan, the doctor-patient relationship has traditionally been characterized by a power imbalance that may contribute to communication gaps. To date, however, the link between patients' health literacy levels and their understanding of doctors' explanations of medical conditions and treatment has yet to be fully examined in Japan.

Objective: The purpose of this study was to investigate the association between patients' health literacy level and their understanding of doctors' explanations.

Methods: This was a cross-sectional study analyzing data derived from 11,217 questionnaires collected in July 2021 from participants of the Yamagata Study, a community-based cohort study implemented by Yamagata University since 2009.

Key results: The results showed lower health literacy was associated with poorer understanding of physicians' explanations, adjusting for potential confounding factors. In addition to low health literacy, factors associated with lower comprehension were being male, not having a regular family doctor, and having lower self-perceived levels of health and happiness.

Conclusions: The results suggest that health care professionals need to communicate with patients according to their health literacy level and ensure they fully understand their medical condition and treatment. Medical providers need to create a better health-literate environment to enable patients and families to make decisions by themselves.
