educing salt and increasing potassium intake are recommended lifestyle modifications for patients with hypertension. The estimated 24-h urinary salt excretion value from spot urine using Tanaka’s formula and the salt check-sheet scores, questionnaire-based scores of salt intake, are practical indices of daily salt intake. However, few studies have evaluated salt intake with these methods in hypertensive outpatients. We examined salt and potassium intake with the spot urine method and the salt check-sheet scores of hypertensive outpatients in a multi-facility, real-world setting and examined whether the salt or potassium intake evaluated with these methods related to inadequate blood pressure control. Hypertensive outpatients from 12 medical facilities in the Okinawa prefecture were enrolled from November 2011 to April 2014 (n = 1559, mean age 63.9 years, 46% women). The mean blood pressure, urinary salt excretion value, urinary potassium excretion value, and total score on the salt check-sheet were 129/75 mmHg, 8.7 g/day, 1.6 g/day, and 10.4 points, respectively. The urinary salt excretion value and total score on the salt check-sheet but not urinary potassium excretion value were associated with inadequate blood pressure control (≥140/90 mmHg). Higher body mass index, estimated glomerular filtration rate, urinary potassium excretion value, total score on the salt check-sheet, and presence of inadequate blood pressure control were associated with high urinary salt excretion (≥10.2 g/day). In conclusion, hypertensive outpatients with high urinary salt excretion values estimated using Tanaka’s formula or with high scores on the salt check sheet may be candidates for more intensive salt reduction guidance.

建议高血压患者改变生活方式，减少盐分和增加钾的摄入量。使用 Tanaka 公式估算的 24 小时尿盐排泄值和盐检查表评分（基于问卷的盐摄入量评分）是每日盐摄入量的实用指标。然而，很少有研究评估这些方法在高血压门诊患者中的盐摄入量。我们在多设施、真实世界的环境中使用点尿法和高血压门诊患者的盐检查表评分检查了盐和钾的摄入量，并检查了用这些方法评估的盐或钾摄入量是否与血压控制不足有关。2011 年 11 月至 2014 年 4 月，冲绳县内 12 家医疗机构的高血压门诊患者入组。n = 1559，平均年龄 63.9 岁，女性占 46%）。平均血压、尿盐排泄值、尿钾排泄值和盐检查表总分分别为129/75 mmHg、8.7 g/day、1.6 g/day和10.4分。盐检查表上的尿盐排泄值和总分而不是尿钾排泄值与血压控制不足（≥140/90 mmHg）相关。较高的体重指数、估计的肾小球滤过率、尿钾排泄值、盐检查表上的总分以及血压控制不足与尿盐排泄量高（≥10.2 g/天）相关。综上所述，
