Estimation Method of 24-hour Urinary Sodium Excretion by Using Spot Urine for Chinese Population

February 28, 2022 updated by: Yaguang Peng, Beijing Children's Hospital

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.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

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.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.
