Is Serum Uric Acid to Creatinine Ratio Associated with Hypertension and Metabolic Syndrome in Children with Obesity?

Background Childhood obesity is a global health problem with increasing prevalence, leading to long-term cardiovascular complications. Research conducted on adults has established a correlation between serum uric acid to creatinine ratio (SUA/Cr) and metabolic syndrome (MetS) components. The study investigates the relationship between SUA/Cr and hypertension (HT) and MetS components in children with obesity. Methods A total of 103 children with obesity who underwent ambulatory blood pressure measurement (ABPM) were included the study and patients were divided into two groups "HT" (n=60) and "Normal" (n=43). Demographic, anthropometric, and laboratory characteristics were retrospectively analyzed. Results The study included 103 children (42 female, 61 male) with a mean age of 13.7 +/- 2.9 years. HT prevalence was significantly higher in patients with severe obesity and dyslipidemia (p=0.045, p=0.01). Males exhibited significantly higher SUA/Cr than females (p<0.001). However, SUA/Cr showed no significant differences between patients with and without HT, MetS, dyslipidemia, or hyperglycemia (p=0.69, p=0.64, p=0.90, p=0.37). Furthermore, linear regression analysis did not establish a significant effect of SUA/Cr on ABPM parameters (p>0.05). Conclusion In our cohort, no significant association was found between SUA/Cr and HT, as well as MetS components in children with obesity. These findings highlight the need for further investigation into the complex mechanisms regulating uric acid metabolism, obesity, and cardiovascular risk in children.
