The goal of this observational study is to investigate the impact of metabolic comorbidities on outcomes in elderly Chinese adults, through two parallel sub-cohorts: one comprising elderly individuals without chronic kidney disease (CKD) at baseline, and one comprising elderly patients with established CKD. The main questions it aims to answer are: Do metabolic diseases (diabetes, hypertension, hyperlipidemia, hyperuricemia, calcium-phosphorus disorders) increase the risk of incident CKD, major adverse cardiovascular events (MACE), and all-cause mortality in elderly individuals without CKD at baseline? What are the optimal diagnostic thresholds and criteria for CKD in the elderly population? How do metabolic comorbidities affect long-term outcomes - including all-cause mortality, end-stage renal disease (ESRD), and cardiovascular events - in elderly patients with established CKD? What is the comorbidity profile and disease burden of elderly CKD patients in China? Participants in both sub-cohorts will: Undergo baseline assessments including laboratory tests and clinical evaluations. Provide longitudinal follow-up data through scheduled clinic visits and medical record linkage. Contribute to a large-scale cohort of 100,000 elderly participants across multiple centers in China.
