Abstract
Background: Controlled attenuation parameter (CAP) is a kind of widespread popular parameter to evaluate various types of hepatic steatosis by liver ultrasound transient elastography. We investigated the relationship between serum uric acid (SUA) and CAP without hepatitis B and C virus-infected in the United States adults, data from National Health and Nutrition Examination Survey (NHANES).Methods: The present study was cross-sectional research. 4319 American men and women participants ≥18 years old, without B and C hepatitis, were included in our analysis. There are some measures to evaluate the association between SUA and CAP by multivariate logistic regression analyses, fit smoothing curves, generalized additive models, two-piecewise linear regression model and subgroup analyses.Results: There was a positive association between the value of SUA and CAP by multivariate logistic regression analyses after adjusting for various confounders. Besides, the inflection point of non-linear curve relationship was identified as 4.3 mg/dL, for SUA <4.3 mg/dL, the effect size is 10.6 (P< 0.01); Correspondingly, SUA≥ 4.3 mg/dL, the effect size is 4.3 (P< 0.01).Finally, SUA was positively associated with glycohemoglobin less than 6.5% individuals (β =7.3, P< 0.01) and Fasting glucose less than 7.0 mmol/L individuals (β = 6.8, P< 0.01) in the subgroup analysis. Conclusions: Our research found the relationship between SUA and CAP is non-linear. Subgroup analysis indicated that the positive association between SUA and CAP were showed in non-diabetic patients but not in diabetic.
