Low health literacy (HL) has been associated with poor chronic disease management and adverse outcomes. However, reports on HL in predialysis chronic kidney disease (CKD) patients are limited in Japan.
From August 2019 to February 2020, the European Health Literacy Survey (Japanese version) and a patient background survey (highest level of education, income, social activities, and exercise habit) were conducted on adult predialysis CKD patients. We compared clinical parameters in two groups according to the average HL score of a healthy Japanese population. In addition, a median value of 42 items was used as a cutoff for extracting CKD patient background factors associated with HL since HLS-EU-Q47 included five items related to physical activity and exercise.
Valid responses were received from 200 patients. Median general HL index was 25.2 points. The high-HL group (≥ 25.3 points) showed a low proportion of male (56.7% vs. 70.9%, p = 0.038), high social activities (69.1% vs. 48.5%, p = 0.003), and high exercise habit (36.1% vs. 13.6%, p < 0.001). In the multivariate analysis, social activity [OR (95% CI); 2.12 (1.16-3.89), p = 0.015] and exercise habit [OR (95% CI); 2.39 (1.16-4.90), p = 0.018] were extracted as the only significant variable.

低健康素养（HL）与慢性疾病管理不善和不良结局有关。然而，在日本，关于透析前慢性肾脏病（CKD）患者 HL 的报告有限。
从 2019 年 8 月到 2020 年 2 月，对成年透析前 CKD 患者进行了欧洲健康素养调查（日语版）和患者背景调查（最高教育水平、收入、社会活动和运动习惯）。我们根据健康日本人群的平均 HL 评分将两组的临床参数进行了比较。此外，由于 HLS-EU-Q47 包含与身体活动和运动有关的五个项目，因此使用 42 个项目的中位数作为提取与 HL 相关的 CKD 患者背景因素的截止值。
共收到 200 例有效回复。一般 HL 指数中位数为 25.2 分。高 HL 组（≥25.3 分）男性比例较低（56.7% vs. 70.9%，p=0.038），社会活动较高（69.1% vs. 48.5%，p=0.003），运动习惯较高（36.1% vs. 13.6%，p<0.001）。在多变量分析中，社会活动[OR（95%CI）；2.12（1.16-3.89），p=0.015]和运动习惯[OR（95%CI）；2.39（1.16-4.90），p=0.018]是唯一有意义的变量。
日本透析前 CKD 患者的 HL 与高社会活动和运动习惯有关。
