HUA, hyperuricemia; PAR, population attributable risk; CI, confidence interval.

^*The number of HUA cases in the 20–29 and 70–80 years groups among female was small, so we combined them with the next age-group to get a more stable estimation. Overweight/obesity was defined as body mass index ≥25 kg/m².

^aPAR was adjusted for age, residential areas, and overweight/obesity. The overall PAR was additionally adjusted for study sites.
