Physical activity (PA) may lower serum urate levels but does not causally reduce gout risk. This Mendelian randomization study found no reverse association between urate or gout and PA.
Area of Science:
- Genetics
- Epidemiology
- Metabolic Diseases
Background:
- Physical activity (PA) is linked to reduced gout risk, but evidence is inconsistent.
- The causal relationship between PA, serum urate, and gout remains unclear.
Purpose of the Study:
- To investigate the causal effect of PA on serum urate concentrations and gout risk.
- Utilized a bidirectional Mendelian randomization (MR) approach to assess causality.
Main Methods:
- Employed genome-wide association study (GWAS) data from UK Biobank for PA and Global Urate Genetics Consortium for serum urate and gout.
- Applied various MR methods including inverse-variance weighted and weighted median.
Main Results:
- Genetic predisposition to accelerometer-measured PA was associated with decreased serum urate concentrations.
- No significant causal association was found between PA and gout risk.
- Reverse MR analysis showed no association between serum urate/gout and PA.
Conclusions:
- PA may lower serum urate concentrations, but does not appear to reduce gout risk.
- Serum urate concentrations and gout risk do not influence PA levels.
