OBJECTIVE: The pathophysiological role of cystatin C in cardiometabolic disorders is not completely explored in young population. On the other hand, together with the increase in obesity, dyslipidemia and insulin resistance (IR) are often observed even in youngsters. The aim of the study was to investigate the relationship between cystatin C and triglycerides-to-high-density lipoprotein cholesterol ratio (TG/HDL-c), as an indicator of dyslipidemia and a surrogate marker of IR in the cohort of adolescent girls ages between 16-19 years.

PATIENTS AND METHODS: A total of 99 girls were included in the study. Anthropometric and biochemical parameters were provided. Associations of biochemical markers with TG/HDL-c ratio were tested using univariable and multivariable ordinal regression analysis for TG/HDL-c ratio tertiles as dependent variable.

RESULTS: In univariate analysis, cystatin C levels were significantly associated with TG/HDL-c ratio (OR=1.813; 95% CI: 1.190-2.757, p=0.005). Furthermore, multivariate analysis revealed that cystatin C was an independent predictor of TG/HDL-c ratio when body mass index and high sensitivity C-reactive protein (i.e., markers that were significantly correlated with TG/HDL-c ratio in Spearman’s correlation analysis) were included in the Model. Adjusted odds for cystatin C (OR=1.621; 95% CI: 1.028-2.552, p=0.037) demonstrated that rise in cystatin C by 0.1 mg/L increased the probability for higher TG/HDL-c tertile group by 1.621 times.

CONCLUSIONS: Serum cystatin C levels are associated with TG/HDL-c ratio in adolescent girls. Longitudinal studies are needed to confirm the causal relationship between cystatin C and TG/HDL-c ratio and to further explore its diagnostic and therapeutic potential in dyslipidemia and insulin resistance in young population.
