Exploration of the association between new "Life's Essential 8" with hyperuricemia and gout among US adults.

BACKGROUND

Previous researches have reported the relationship between uric acid and cardiovascular disease. We aimed to investigate the association of Life's Essential 8, a recently updated measurement of cardiovascular health, with the prevalence of hyperuricemia (HUA) and gout among US adults. Additionally, we also explored the relationship between LE8 and all-cause mortality among patients with HUA or gout.

METHODS

Participants from the National Health and Nutrition Examination Survey in 2007-2016 were involved in this study. LE8 score was categorized into low, moderate, high CVH groups according to American Heart Association definitions. Multivariable logistic regression and cox regression analyses, restricted cubic spline models, subgroup analysis and sensitivity analysis were used to explore the associations.

RESULTS

A total of 23,619 adult participants were included in this study, which included 4,775 hyperuricemia patients and 1,055 gout patients. Among all participants, the overall median LE8 score was 65.62 (21.25) and the prevalence of hyperuricemia and gout of were 20.2% and 4.5%, respectively. After fully adjusted the potential confounders, participants in high CVH group had a lower prevalence of hyperuricemia and gout compared with the low CVH group, with a OR (95%CI) of 0.50 (0.39-0.63) and 0.50 (0.30-0.82), respectively. The restricted cubic spline showed a significantly inverse relationship between LE8 and hyperuricemia and gout. Similar patterns were also identified in the association between LE8 scores and all-cause mortality in HUA and gout patients.

CONCLUSIONS

Higher LE8 scores are associated with lower risk and lower all-cause mortality of HUA and gout among US adults. Adherence to optimal CVH metrics may be an appropriate prevention and management strategy for reducing the socioeconomic burden of hyperuricemia and gout.
