摘要

Background and aims

Chronic kidney disease (CKD) is creating an ever heavier global health burden with population ageing. This study aimed to examine the longitudinal associations of remnant cholesterol (RC) with CKD morbidity in a large high-risk population (type 2 diabetes and hypertension).

Methods

A total of 11,881 participants who participated in annual health examinations from 2021 to 2023 were included in our analysis. The Cox proportional hazards model was performed to analyze the associations of baseline RC, cumulative RC, and variability of RC with CKD morbidity. The cross-lagged panel analysis was used to examine the temporal relationship between RC and renal function.

Results

The results of the multivariable-adjusted models showed that higher baseline, cumulative RC, and variability of RC were related to higher risks of developing CKD, the adjusted HR (95% CI) comparing tertile 3 with tertile 1 were 1.26 (95% CI 1.10–1.45), 1.33 (95% CI 1.16–1.52), 1.36 (95% CI 1.20–1.55), respectively. Stratified analysis found that gender did not change these associations. Compared with individuals in the low cumulative and variability RC group, those in the high cumulative and variability RC group had a 1.62 times higher risk of CKD (95% CI: 1.34–1.96). The cross-lagged panel analysis showed that the increase in RC levels may precede the decrease in eGFR.

Conclusions

High baseline level, cumulative exposure to RC, and variability of RC are associated with increased CKD risk. Therefore, monitoring RC-related parameters is crucial to delay the occurrence and development of CKD in high-risk populations.
