AIMS: While glomerular hyperfiltration (GHF) emerged as a risk factor for cardiovascular disease (CVD), little is known about the association between GHF and blood lipid profile. We aimed to examine the association between GHF and blood lipid parameters in adults with few comorbidities.
METHODS: A cross-sectional study was performed on adults undergoing health screening in Osaka, Japan. Adults with a history of heart disease or stroke, those with diabetes mellitus, chronic kidney disease (estimated glomerular filtration rate (eGFR) ＜60 mL/min/1.73m2), or those using lipid-lowering medication were excluded. The outcome was GHF, defined as ＞95th percentile of eGFR after stratification by age and sex. The exposure was blood lipid parameters, including total cholesterol, low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), triglyceride (TG), non-HDL-C, TG/HDL-C ratio, small dense LDL-C (sdLDL-C), and sdLDL-C/LDL-C ratio. Associations between blood lipid parameters and GHF were examined by multiple logistic regression under a Bayesian framework, adjusted for established risk factors of GHF, including body mass index, blood pressure, and lifestyle factors.
RESULTS: Of 17,288 eligible individuals (mean age 50.1±9.9 years; 45.5% women), 853 individuals (4.9%) had GHF. Multiple logistic regression analyses demonstrated an association between a higher sdLDL-C/LDL-C ratio and GHF (odds ratio (OR) = 1.51, 95% credible interval (CrI) 1.21-1.88). LDL-C showed an inverse association with GHF (OR = 0.94, 95% CrI 0.92-0.97).
CONCLUSION: Our findings demonstrated an independent association between a higher sdLDL-C/LDL-C ratio and GHF. The role of an sdLDL-C/LDL-C ratio in GHF development and CVD risk merits further investigation.
