Hyperuricemia is associated with more cardiometabolic risk factors in hypertensive younger Chinese adults than in elderly

Numerous studies have shown that hyperuricemia (HUA) is associated with cardiovascular and renal outcomes, but few studies specifically explored the effect of age on this relationship. Therefore, our study aimed to explore the relationship between HUA and other cardiometabolic risk factors in different age groups. This cross-section study used the data from Survey on uric acid in Chinese subjects with essential hypertension (SUCCESS). We performed multivariate logistic regressions in different age groups. After adjusting for potential confounders, among young and middle-aged adults less than 60, HUA was associated with higher body mass index (BMI, adjusted OR = 1.114, 95% CI: 1.057-1.174), higher fasting blood glucose (FBG, adjusted OR = 1.099, 95% CI: 1.003-1.205), triglycerides (TG, adjusted OR = 1.425, 95% CI: 1.247-1.629), higher low-density lipoprotein cholesterol (LDL-C, adjusted OR = 1.171, 95% CI: 1.025-1.337), and lower estimated glomerular filtration rate (eGFR, adjusted OR = 0.992, 95% CI: 0.988-0.996). Among elderly adults 60 years or older, HUA was associated with higher SBP (adjusted OR = 1.024, 95% CI: 1.005-1.042), higher TG (adjusted OR = 1.716, 95% CI: 1.466-2.009), and higher LDL-C (adjusted OR = 1.595, 95% CI: 1.366-1.863). HUA is associated with more cardiometabolic risk factors in younger adults with hypertension (HT). Comprehensive management of HT with HUA is needed in clinical settings.
