“…In the current study, we used early morning spot urine samples to estimate daily salt intake. Previous reports have shown that the urine sodium‐to‐creatinine ratio determined from early morning spot urine samples correlated well with urinary sodium excretion values calculated over a 24‐hour period . Our own results confirmed that estimates of daily salt intake based on the spot urine samples were highly reproducible, with little variation observed from day to day for each individual (Table ).…”

“…Previous reports have shown that the urine sodium-to-creatinine ratio determined from early morning spot urine samples correlated well with urinary sodium excretion values calculated over a 24-hour period. [13][14][15][16][17] Our own results confirmed that estimates of daily salt intake based on the spot urine samples were highly reproducible, with little variation observed from day to day for each individual (Table 1). Using this method, we found that excessive salt intake reduced the efficacy of ddavp treatment in Japanese patients with nocturnal enuresis.…”

Aim We investigated whether the daily salt intake of children with nocturnal enuresis influenced their response to 1‐desamino‐8‐D‐arginine vasopressin therapy. Methods This study comprised 129 children (67.4% boys) with a median age of 9.2 years (range 7.2‐10.4) with monosymptomatic nocturnal enuresis who were seen at Kansai Medical University Hospital, Osaka, Japan, from 2013 to 2017. Urinary sodium concentrations were determined using a spot urine test, and the children were divided into appropriate (n = 55) and excessive salt intake (n = 74) groups based on Japanese Government guidelines. After a month of therapy, the treatment responses were compared for 39 and 50 children, respectively. Results There were no significant differences in the urea nitrogen‐to‐creatinine or calcium‐to‐creatinine ratios in the two groups. However, the excessive salt intake group showed a significantly reduced treatment response to the appropriate salt intake group. In addition, the excessive and appropriate salt intake groups showed median efficacy ratios of 8.2% and 21.8%, respectively, based on intention‐to‐treat analysis (P = 0.029) and 12.0% and 30.8% based on per‐protocol analysis (P = 0.029). Conclusion High daily salt intake significantly reduced the efficacy of ddavp therapy for nocturnal enuresis and consumption should be controlled during treatment.

“…Ohta et al reported that urinary salt excretion is reduced by the use of a self-monitoring device by hypertensive patients, and that BW is significantly correlated with salt excretion (14). Meland et al also reported that during a randomized controlled trial for 12 weeks, BP decreased significantly in hypertensive patients who were using self-monitoring of urine for Cl -in addition to receiving nutritional instruction (15).…”

“…Ohta et al also reported that salt excretion measured with a self-monitoring device correlated well with that determined by 24-h home urine evaluation in hypertensive subjects (r=0.63, P<0.01) (14). Since the self-monitoring device can be used at home to evaluate daily urinary salt excretion, it can be used as a strong motivational tool to help individuals reduce salt intake.…”

Abstract. This study aimed to examine the usefulness of the self-monitoring of urinary salt excretion for educating individuals about the risk of excessive dietary salt intake. The subjects were 30 volunteers (15 men and 15 women) not consuming anti-hypertensive medication. The subjects measured urinary salt excretion at home for 4 weeks using a self-monitoring device. Blood pressure (BP), anthropometric variables and nutritional variables (by a dietary-habits questionnaire) were measured before and after the measurement of urinary salt excretion. Statistical analyses were performed, including paired t-tests, Chi-square test, Pearson's product moment correlation coefficient and multiple linear regression analysis. In all subjects, the average urinary salt excretion over 4 weeks was 8.05±1.61 g/day and the range (maximum-minimum value) was 5.58±2.15 g/day. Salt excretion decreased significantly in weeks 3 and 4 (P<0.05 and P<0.01, respectively). Diastolic BP decreased from 77.7±14.3 (at baseline) to 74.3±13.3 after 4 weeks (P<0.05), while systolic BP and anthropometric variables remained unchanged. Nutrition surveys indicated that energy intake was correlated with salt intake both before and after the measurements; changes in both variables during the observation period were correlated (r=0.40, P<0.05). The percentage of subjects who were aware of the restriction in dietary salt intake increased from 47 to 90%. In conclusion, daily monitoring of the amount of urinary salt excretion using a selfmonitoring device appears to be an effective educational tool for improving the quality of life of healthy adults.

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.
