Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 60 years and older
  • All sexes
  • Healthy volunteers accepted
  • Adult, Older adult

Study population: The study population comprises adults aged 60 years or older selected from two established Chinese cohorts. The Rugao Longevity and Ageing Study primarily includes community-dwelling older adults, whereas the Shanghai Older-Adult Cohort includes older adults with comorbid conditions. Eligible participants had a baseline estimated glomerular filtration rate greater than 60 mL/min/1.73 m² and the clinical, follow-up, and biospecimen data required for the relevant analyses.

Who may be able to join

  • Enrollment in the Rugao Longevity and Ageing Study or the Shanghai Older-Adult Cohort.
  • Age 60 years or older, of either sex, with a baseline estimated glomerular filtration rate greater than 60 mL/min/1.73 m².
  • Availability of the baseline data required for the study, including blood pressure, body weight, body mass index, smoking and alcohol use, surgical history, family history, complete blood count, liver function, electrolytes, kidney function, serum cystatin C, blood glucose, urinalysis, and urinary albumin-to-creatinine ratio.
  • Availability of follow-up information sufficient to ascertain the prespecified clinical outcomes.
  • Clinically stable condition and adequate ability to understand and communicate at enrollment in the parent cohort.
  • Written informed consent for participation and the permitted research use of clinical data and stored biospecimens.

Who cannot join

  • Missing essential baseline or follow-up data required for the relevant analysis.
  • Unavailability of stored blood or urine specimens required for the planned biomarker analysis.
  • Missing information on lifestyle, health-related behaviors, or social support required for the relevant analysis.

About this study

Official title: Comprehensive Clinical Assessment and Management of Kidney Function Decline in Older Adults and Development of an Early Warning System

This completed observational cohort study evaluates a comprehensive set of clinical and molecular markers of kidney function in two established cohorts of Chinese adults aged 60 years or older. The study assesses markers reflecting glomerular filtration, kidney tubular transport, and kidney endocrine function and evaluates their associations with kidney failure, cardiovascular and cerebrovascular events, and all-cause mortality. It also compares approaches to estimating glomerular filtration rate and develops and internally validates an early-warning model for kidney function decline. Existing baseline and follow-up data and stored serum and urine specimens are used. No intervention or additional study-specific clinical procedure is administered.

Read the detailed description

The study includes 5,588 participants, comprising 1,788 participants from the Rugao Longevity and Ageing Study and 3,800 participants from the Shanghai Older-Adult Cohort. The study uses existing demographic, lifestyle, clinical, and laboratory data, longitudinal follow-up information, and measurements obtained from stored serum and urine specimens. No intervention is assigned, and no additional study-specific examination or biospecimen collection is performed.

Markers reflecting glomerular filtration, kidney tubular transport, and kidney endocrine function are evaluated in relation to incident kidney failure, cardiovascular and cerebrovascular events, and all-cause mortality. Approaches to estimating glomerular filtration rate and combinations of kidney function-related biomarkers are compared for prognostic assessment. Multivariable linear, logistic, and Cox proportional hazards regression models are used, as appropriate, to evaluate associations while accounting for potential confounding factors.

For prediction modeling, the analytic sample is divided in a 7:3 ratio into model-development and internal-validation sets. Statistical learning and machine-learning methods, including random forests, decision trees, support vector machines, and neural-network approaches, are evaluated. Cross-validation is used during model development and model selection. The study also supports the development of a secure, access-controlled data-sharing and analytics platform.

Study groupRoleWhat they receive
Rugao Longevity and Ageing Study CohortThis cohort comprises eligible older adults from the established Rugao Longevity and Ageing Study. Participants contribute existing baseline and follow-up data and, when available, stored serum and urine specimens. No intervention is assigned. Clinical and molecular markers of kidney function are evaluated in relation to subsequent kidney failure, cardiovascular and cerebrovascular events, and all-cause mortality.
Shanghai Older-Adult CohortThis cohort comprises eligible older adults with comorbid conditions from the established Shanghai Older-Adult Cohort. Participants contribute existing baseline and follow-up data and, when available, stored serum and urine specimens. No intervention is assigned. Clinical and molecular markers of kidney function are evaluated in relation to subsequent kidney failure, cardiovascular and cerebrovascular events, and all-cause mortality.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Incident End-Stage Kidney Disease

    First occurrence of end-stage kidney disease documented in cohort follow-up or clinical records.

    Measured: From cohort baseline through the end of available follow-up, up to 10 years

  2. Incident Cardiovascular or Cerebrovascular Event

    First occurrence of a clinically documented cardiovascular or cerebrovascular event, including coronary heart disease, myocardial infarction, heart failure, or stroke, ascertained from cohort follow-up and medical records.

    Measured: From cohort baseline through the end of available follow-up, up to 10 years

  3. All-Cause Mortality

    Death from any cause, ascertained from survival follow-up and death records.

    Measured: From cohort baseline through the end of available follow-up, up to 10 years

Questions about this trial

What is this clinical trial studying?

An observational study of Kidney Function Decline and Chronic Kidney Disease, run by Huashan 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 6 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 14 Aug 2026. 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?

Incident End-Stage Kidney Disease (time frame: From cohort baseline through the end of available follow-up, up to 10 years). The study lists 3 primary outcomes in all. 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 14 Aug 2026.
