Salt intake and blood pressure in Iranian children and adolescents: a population-based study

Published in BMC Cardiovascular Disorders on the 2nd of February 2021, Emamian et al conducted a cross-sectional study to investigate the daily salt intake levels of schoolchildren aged 9-15 years, and its association with high blood pressure in an area with a high prevalence of hypertension (Shahroud, northeast Iran). A subsample of 5,620 schoolchildren provided […]

Urinary Sodium and Potassium Levels and Blood Pressure in Population with High Sodium Intake

Published in Nutrients on 10 November 2020, Song et al conducted a cross-sectional analysis in 2,653 Korean adult men and women to examine the association between urinary sodium-to-creatinine ratio and potassium-to-creatinine ratio measured by overnight half-day urine samples with blood pressure. A validated food frequency questionnaire was also used to assess food intake. The study […]

Change in mean salt intake: 24-h urine versus overnight and spot urine samples

Published in the Nutrition Journal on 6th December 2020, Santos et al conducted a systematic review and meta-analysis to compare the estimates of change in mean population salt intake based on 24-h urine and overnight/spot urine samples. From 14 studies, the pooled mean change in salt intake was − 0.43 g/day (95% CI − 1.16 […]

The association between sodium and blood pressure is influenced by methods of evaluating the completeness of 24-h urine collections

Published in Nutrients on 11 September 2020, Abu Mohd Naser et al investigated whether different methods of evaluating the completeness of 24-h urine samples influences the association between sodium intake and health outcomes. A secondary analysis of three cohort studies from Bangladesh was conducted using cross-sectional sodium intake   and blood pressure measures across several visits […]

Identifying sodium intake using dietary behaviours

Published in PLoS One on 15 September 2020, Okada and Takimoto conducted a cross-sectional analysis to develop a brief screening method for determining sodium intake in order to raise public awareness of Dietary Reference Intakes in Japan. Self-administered questionnaires from one-day dietary records by a semi-weighed method within the 2015 National Health and Nutrition Survey […]

Spot urine samples should not be used to examine sodium‐disease relationships

Published in the Journal of Clinical Hypertension on 10 September 2020, Peterson et al. conducted a systematic review on the use of spot urine samples to examine sodium-disease relationships. As part of the Science of Salt series of regularly updated reviews, this study critically appraised relevant studies from November 2018 to August 2019. Only two […]

High sodium and low potassium intakes in Kazakhstan using 24-h urinary sodium excretion

Published in the European Journal of Nutrition, Trieu et al analysed the data from two cross sectional surveys that collected 24-h urine samples from participants aged 25-64 years to estimate mean sodium and potassium intake and describe dietary knowledge and behaviour among adults in two different regions of Kazakhstan. The study found the weighted mean […]

A dose-response: reduction of blood pressure by restricting dietary sodium intake

Huang et al conducted systematic review and meta-analysis published in British Medical Journal that examines the dose-response relationship between a reduction in dietary sodium and change in BP. Measured using the gold standard, each 50mmol reduction in 24-hour sodium excretion was associated with a 1.10 mm Hg reduction in SBP and a 0.33 mm Hg […]
