The Cohort Construction Project of Peking University Third Hospital

Condition(s) studied

Investigational drug(s) / intervention(s)

observational study: This is an observational study designed to investigate the mental health status and its influencing factors in the general physical examination population. No interventions are assigned to participants based on a protocol.

Study summary

The specific construction goals for this period include enrolling 100,000 individuals for dynamic follow-up, perfecting the biobank by collecting biological samples from 20,000 individuals, and gathering health questionnaire information from 30,000 people. The near-term goals emphasize the use of health check-up data combined with advanced artificial intelligence technologies to build disease prediction models and explore the association between retinal photographs and overall health status, which will assist in early screening and personalized interventions for high-risk populations. The medium- to long-term goals focus on biological age-related research, utilizing telomere length and multi-omics technologies to assess the differences between biological age and chronological age and analyze their key influencing factors. Data collection will be implemented through the health check-up centers of multiple campuses of PUTH.

Eligibility

Primary outcome measure(s)

• Systolic and Diastolic Blood Pressure — through study completion, an average of 3 year
  Blood pressure will be measured using a standardized mercury sphygmomanometer after at least 5 minutes of rest in a seated position. Both systolic blood pressure (SBP) and diastolic blood pressure (DBP) will be recorded.
• Fasting Lipid Profile (Total Cholesterol, Triglycerides, LDL-C, and HDL-C) — through study completion, an average of 3 year
  Venous blood samples will be collected after at least 8 hours of overnight fasting. Serum levels of total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C) will be measured using an automated biochemical analyzer at the central laboratory of Peking University Third Hospital.
• Fasting Blood Glucose (FBG) — through study completion, an average of 3 year
  Fasting venous blood samples will be collected after at least 8 hours of overnight fasting. Serum glucose levels will be measured using an automated biochemical analyzer at the central laboratory of Peking University Third Hospital.
• Glycated Hemoglobin (HbA1c) — through study completion, an average of 3 year
  Fasting venous blood samples will be collected and analyzed using high-performance liquid chromatography (HPLC) at the central laboratory of Peking University Third Hospital. HbA1c reflects average blood glucose levels over the previous 2 to 3 months.
• Complete Blood Count (CBC) — through study completion, an average of 3 year
  Fasting venous blood samples will be collected and analyzed using an automated hematology analyzer at the central laboratory of Peking University Third Hospital. Key parameters include white blood cell count (WBC), red blood cell count (RBC), hemoglobin (HGB), hematocrit (HCT), mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC), and platelet count (PLT).
• Routine Urinalysis — through study completion, an average of 3 year
  Midstream clean-catch urine specimens will be collected and analyzed using an automated urine analyzer and microscopy at the central laboratory of Peking University Third Hospital. Key parameters include urine specific gravity, pH, protein, glucose, ketones, bilirubin, urobilinogen, nitrite, leukocyte esterase, and microscopic examination of red blood cells, white blood cells, and casts.
• Liver Function Panel — through study completion, an average of 3 year
  Fasting venous blood samples will be collected and analyzed using an automated biochemical analyzer at the central laboratory of Peking University Third Hospital. Key parameters include alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), gamma-glutamyl transferase (GGT), total bilirubin (TBIL), direct bilirubin (DBIL), total protein (TP), and albumin (ALB).
• Renal Function Panel — through study completion, an average of 3 year
  Fasting venous blood samples will be collected and analyzed using an automated biochemical analyzer at the central laboratory of Peking University Third Hospital. Key parameters include serum creatinine (Cr), blood urea nitrogen (BUN), uric acid (UA), and estimated glomerular filtration rate (eGFR) calculated using the CKD-EPI or MDRD equation.
• Pulmonary Assessment — through study completion, an average of 3 year
  Chest X-ray or low-dose chest CT will be performed according to standardized protocols at the Radiology Department of Peking University Third Hospital. Findings will be interpreted by certified radiologists. Results will be reported as presence or absence of pulmonary abnormalities (e.g., nodules, infiltrates, or other clinically significant findings).
• Abdominal Ultrasound Assessment — through study completion, an average of 3 year
  Abdominal ultrasound will be performed according to standardized protocols at the Radiology Department of Peking University Third Hospital for evaluation of the liver, gallbladder, pancreas, spleen, and kidneys. Findings will be interpreted by certified radiologists. Results will be reported as presence or absence of abnormalities in each organ.
• Carotid Artery Ultrasound Assessment — through study completion, an average of 3 year
  Carotid artery ultrasound will be performed according to standardized protocols at the Radiology Department of Peking University Third Hospital for assessment of carotid intima-media thickness (CIMT) and plaque detection. CIMT will be measured in millimeters (mm). Plaque will be reported as present or absent. All findings will be interpreted by certified radiologists.
