Cystatin C serum levels in healthy children are related to age, gender, and pubertal stage.

ABSTRACT: BACKGROUND:This study aims to establish age- and gender-specific cystatin C (CysC) reference values for healthy infants, children, and adolescents and to relate them to pubertal stage, height, weight, and body mass index (BMI). METHODS:Serum CysC and creatinine levels of 6217 fasting, morning venous blood samples from 2803 healthy participants of the LIFE Child study (age 3 months to 18 years) were analyzed by an immunoassay. Recruitment started in 2011; 1636 participants provided at least one follow-up measurement. Percentiles for CysC were calculated. Age- and gender-related effects of height, weight, BMI, and puberty status were assessed through linear regression models. RESULTS:Over the first 2 years of life, median CysC levels decrease depending on height (ß?=?-?0.010 mg/l/cm, p?
