Trial summary

The accurate evaluation of daily salt or sodium intake is difficult to implement in clinical practice and large epidemiological studies. 24-h urinary sodium excretion (USE) is considered the gold standard, but is expensive and has a high participant burden. Read more about this study

About this study

Official title: The Exploratory and Validation Study of Estimation Method of 24-hour Urinary Sodium Excretion by Using Spot Urine for Chinese Children and Adults

The accurate evaluation of daily salt or sodium intake is difficult to implement in clinical practice and large epidemiological studies. 24-h urinary sodium excretion (USE) is considered the gold standard, but is expensive and has a high participant burden. To further explore the association between 24-h USE and spot urines in Chinese population, it was proposed that using collected multiple spot urine samples could be estimated for 24-h USE in Chinese children and adults.

Read the detailed description

Specific Aims

  1. To collect multiple spot urine samples and a 24-h urine sample in a population of Chinese Children and adults. All participants will collect a spot urine in separate jugs during the 24-h period, recording every urination time.
  2. Validate previous finding that 24-h USE is estimated inaccurately by using only the second morning void.
  3. Explore a statistical formula to estimate 24-h USE by multi-time spot urine. The study plan to enroll 200 children and 100 adults to collect a whole 24-h urine spot by spot continuously. After a laboratory examination of sodium concentration from both spot urine samples and 24-h urine sample, the exploratory estimation using multi-spot urine to assess 24-h urinary sodium excretion will analyzed statistically. The validation for the estimation method will be conducted in Chinese population as well.

Urine sodium and potassium concentration in each urine specimen will be determined by ion selective electrode methods and creatinine using enzymatic methods.The model established by using linear model step by step. And the validation analysis conducted through correlation analysis, bias distribution, residual analysis and Bland-Altman plot to assess accuracy. All statistics analysis will be conducted using Statistical Analysis System software version 9.4.

Questions about this trial

What is this clinical trial studying?

An observational study of Urinary Sodium Excretion and Salt Intakes, run by Beijing Children's Hospital at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 2 Mar 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

urinary sodium excretion concentration (time frame: day 1). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 2 Mar 2022.
