Analysis of renal function in a Health Examination Population in Chengdu (2012-2018)

Background Dysfunction of kidney correlates with multiple renal diseases, for instance, chronic kidney disease. However, monitoring the changes of indexes related to renal function may help to early find the potential patients with renal diseases. Methods A cohort of 14,716 participants (8,148 males and 6,568 females) was recruited from the Health Examination Center at West China Hospital, Sichuan University, and was followed up since 2012 to 2018. Four indexes related to renal function, including creatinine (Cr), uric acid (UA), cystatin C (CysC) and urea nitrogen (UN) were selected to monitor the kidney function. Results Levels of CysC, Cr were reduced, and expression of UA was increased in all the participants since 2012 to 2018 overall. In addition, levels of CysC, UA, Cr and UN were higher in males than those in females, and expression of the four indexes was up-regulated in the elderly population compared with those in the younger population since 2012 to 2018 overall. Conclusions The findings suggested that some preventive action may be adopted early and more attention can focus on the health-examination population.
