摘 要:Objective The study aimed to analyze the applicability of the World Health Organization’s exclusionary guidelines for Urinary creatinine(Ucr)in the general Chinese population,and to identify Ucr related *** We conduct a cross-sectional study using baseline data from 21,167 participants in the China National Human Biomonitoring *** linear models and restricted cubic splines(RCS)were used to analyze the associations between explanatory variables and Ucr *** The geometric mean and median concentrations of Ucr in the general Chinese population were 0.90 g/L and 1.01 g/L,*** 9.36%samples were outside 0.3-3.0 g/L,including 7.83%below the lower limit and 1.53%above the upper *** age,male,obesity,smoking,higher frequency of red meat consumption and chronic kidney disease were associated significantly with higher concentrations of *** of the RCS showed Ucr was positively and linearly associated with body mass index,inversely and linearly associated with systolic blood pressure,diastolic blood pressure,triglycerides level,and glomerular filtration rate,and were non-linearly associated with *** The age-and gender-specific cut-off values of Ucr that determine the validity of urine samples in the general Chinese population were *** avoid introducing bias into epidemiologic associations,the potential predictors of Ucr observed in the current study should be considered when using Ucr to adjust for variations in urine dilution.
