“…However, these should be regarded as unreliable and semi-quantitative methods. Recently, a urinary salt sensor, which estimates salt intake by analyzing data in overnight urine using a preinstalled calculation formula, has become available and is expected to increase the reliability (24).

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.

“…19,21 Despite the documented value of HBP in improving medical management and patients' compliance, prospective studies are needed to confirm or refute the findings by Obara et al 12 and to establish whether and how HBP is an effective way for improving BP control in the hypertensive population. The interest in this field is evident by the increasing literature on this topic-even in this journal [22][23][24] -in relation to uptake and implications of home HBP measurements.…”

The best way to measure blood pressure (BP) remains a matter of debate. Office BP recorded by the physician has long been the clinical standard in decision making of therapeutic strategies. However, the clinical value of a single or a few office BP measurements in predicting BP values outside the medical office, and more importantly organ damage and cardiovascular events is rather limited. 1 This is related to two main problems: (1) the poor reproducibility of clinic BP values due to the marked BP variation over time; (2) the alarm reaction to BP measurement by the physician; this phenomenon induces transient increments in BP that may be particularly pronounced in some patients. 2 Over the past three decades, an impressive increase in self BP measurement at home or at the work place and in ambulatory BP measurement by innovative automated devices has taken place. The clinical usefulness of BP measurement at home by semiautomated devices has been investigated over the past 30 years. Several studies have shown that home BP (HBP) measurement, by providing multiple BP recordings under relatively stable conditions and avoiding the so-called 'white-coat effect', is superior to office or clinic BP measurement in terms of reliability, 3 correlation with organ damage 4,5 and predictive value of cardiovascular events. [6][7][8][9] In addition, HBP has been shown to be free of the placebo effect, to improve patients' compliance and to be useful in detecting white-coat and masked hypertension phenomena. 10,11 As a consequence, HBP is now considered a useful procedure not only in complementing clinic BP readings for the management of hypertensive patients in daily practice but also in providing substantial information in clinical research.In this issue of the Journal of Human Hypertension Obara et al. 12 describe the results of a study about the association between HBP measurement and hypertension control among a Japanese population of essential hypertensives in a primary care setting. Factors associated with patients' preference for HBP measurement were also addressed. The conclusion of the study is that home BP measurement that was performed on 77% of the patients was associated with a better control of either home or office BP. Despite some limitations, this paper extends and refines previous evidence on the prevalence of HBP and the impact of this procedure on BP control in a representative population of patients routinely seen in clinical practice. Before addressing the study in detail, some general considerations on HBP measurement might be useful. HBP monitoring in clinical practiceSeveral studies investigated the prevalence of HBP measurement among hypertensive patients in different clinical settings and reported an impressive increase in the use of this procedure over time; this is also testified by the huge growth in the market of automated devices for home BP measurement in affluent societies. In their pioneering survey, Krecke et al. 13 reviewed the prevalence of HBP measurement in eight German investigations ove...
