Objectives: To investigate the relationship between triglycerides to high-density lipoprotein cholesterol ratio (TG/HDL-C) and chronic kidney disease (CKD). Methods: We used data from 216,007 Japanese adults who participated in a nationwide health checkup program. Men (n=88,516) and women (n=127,491) were grouped into quartiles based on their TG/HDL-C levels (<1.26, 1.26-1.98, 1.99-3.18, and >3.18 in men; <0.96, 0.96-1.44, 1.45-2.22, and >2.22 in women). We cross-sectionally assessed the association of TG/HDL-C levels with CKD [defined as an estimated glomerular filtration rate (eGFR) of <60mL/min/1.73m2 (low eGFR) and/or proteinuria (defined as urinary protein ≥1+ on dipstick testing)], low eGFR, and proteinuria. Results: The prevalence of CKD, low eGFR, and proteinuria increased significantly with elevating quartiles of TG/HDL-C in both genders (all P for trend <0.001). Participants in the highest quartile of TG/HDL-C had a significantly greater risk of CKD than those in the lowest quartile after adjustment for the relevant confounding factors (odds ratio: 1.57, 95% confidence interval: 1.49-1.65 in men; 1.41, 1.34-1.48 in women, respectively). Furthermore, there were significant associations with low eGFR and proteinuria. In stratified analysis, the risk of CKD increased linearly with greater TG/HDL-C levels in participants with and without hypertension, diabetes, and obesity. Moreover, higher TG/HDL-C levels were relevant for CKD, especially in participants with hypertension and diabetes (P for interaction <0.001, respectively). Conclusions: An elevated TG/HDL-C is associated with the risk of CKD in the Japanese population.
