评估个人的盐摄入量对于提供有关盐限制的指导是必要的。然而，现有的评估盐摄入量的方法既有优点也有局限性。因此，在选择评价方法时应考虑其对患者和医疗设施环境的适宜性。本研究的目的是通过比较24小时尿盐排泄的反应来调查一份简短的自我管理饮食史问卷（BDHQ）的有效性。本研究共纳入136例高血压门诊患者（男性54例，女性82例）。所有受试者均给予BDHQ，并进行24小时家庭尿液收集。BDHQ评估的能量调整盐摄入量为12.3(95%置信区间：11.8-12.9)g /天，24小时尿液收集评估的尿盐排泄量为9.0 (8.4-9.5)g /天。BDHQ评估的能量调整盐摄入量与24小时尿液收集评估的尿盐排泄量显著相关（r= 0.34， P< 0.001）。综上所述，BDHQ评估的预估盐摄入量与24小时尿盐排泄量相关性虽弱，但显著。在临床实践中，利用这两种方法来评估个人的盐摄入量似乎很重要，以便为盐限制提供充分的指导。
Assessing an individual’s salt intake is necessary for providing guidance with respect to salt restriction. However, the methods that exist for assessing salt intake have both merits and limitations. Therefore, the evaluation methods should be selected for their appropriateness to the patients and the environment of the medical facilities. The purpose of the present study was to investigate the validity of a brief self-administered diet-history questionnaire (BDHQ) by comparing the responses with 24-h urinary salt excretion. A total of 136 hypertensive outpatients (54 men and 82 women) were included in this study. All subjects were given the BDHQ and performed 24-h home urine collection. The energy-adjusted salt intake as assessed by the BDHQ was 12.3 (95% confidence interval: 11.8–12.9) g per day, and the urinary salt excretion evaluated by 24-h urinary collection was 9.0 (8.4–9.5) g per day. The energy-adjusted salt intake assessed by the BDHQ correlated significantly with the urinary salt excretion evaluated by 24-h urinary collection (r= 0.34, P< 0.001). In conclusion, the estimated salt intake evaluated by the BDHQ weakly, but significantly, correlated with 24-h urinary salt excretion. In clinical practice, it seems important to utilize both methods to assess an individual’s salt intake in order to provide adequate guidance for salt restriction.
