Association between serum uric acid and relative hand grip strength in comparison with metabolic syndrome components

Objectives: To investigate the association between serum uric acid (UA) and relative hand grip strength (HGS) in comparison with metabolic syndrome components. Methods: We analyzed the data of 5247 Korean adults aged >= 20 years (2422 men and 2825 women) who participated in the KNHNES VII (2018). Results: Among women, relative HGS was significantly lower in participants with hyperuricemia (1.65 +/- 0.04) than in those without (1.95 +/- 0.01) and was significantly decreased in the highest quartile (4Q: 1.77 +/- 0.02) of serum UA compared with that in the lowest quartile (1Q: 1.98 +/- 0.02). Among men, relative HGS was lower in participants with hyperuricemia (3.09 +/- 0.04 vs. 3.16 +/- 0.02) and decreased in 4Q (3.08 +/- 0.03) of serum UA compared with that in 1Q (3.15 +/- 0.03); however, these results were not statistically significant. In age- and multivariate-adjusted analyses in men, relative HGS was significantly lower in 4Q compared with that in 1Q in model 1 (adjusted for age), but there were no significant differences in model 2 (adjusted for age, BMI, and waist circumference) and model 3 ( adjusted for age, BMI, waist circumference, systolic and diastolic blood pressure, fasting blood glucose, triglycerides, and high-density lipoprotein cholesterol). Meanwhile, in women, relative HGS was significantly decreased in 4Q compared with that in 1Q in all models. Conclusions: A significant inverse correlation was observed between serum UA levels and relative HGS in women, and their significance was maintained even after adjusting for age and metabolic syndrome components.
