Purpose: Bisphenol A (BPA) is endocrine disrupting chemicals used to manufacture plastics such as epoxy resins and polycarbonate polymers. BPA has weak estrogenic and strong anti-androgenic effects and has also been linked to disruption of thyroid function in previous studies. This study aims to investigate the relationship between urinary bisphenol A exposure in early childhood and thyroid hormone of pubertal children in Korea.M...

Introduction: Adrenarche refers to the increase in adrenal androgen synthesis. However, process of adrenal androgen production in early childhood remains to be elucidated. The aim of this study was to evaluate changes in adrenal androgen levels and steroidogenic enzyme activities associated with adrenarche using a prospective cohort.Methods: A total of 229 children (124 boys, 52.4%), who had participated in the Envir...

Backgrounds: Perfluoroalkyl compounds (PFCs) have been suggested as potential thyroid disrupting chemicals. However, previous studies about the associations between PFCs and childhood thyroid function are scarce, and inconclusive. We evaluated the PFC exposure in Korean preschool children, and investigated the temporal relationship with thyroid hormone concentration.Methods: From a prospective the Environment and Develop...

Purpose: We investigated the prevalence of subclinical hypothyroidism (SCH) and its risk factors in prepubertal children at age 6. We also evaluated the prevalence of thyroid nodule or cyst and its relationship with SCH in prepubertal children.Methods: From the Environment and Development of Children (EDC) cohort study, 458 prepubertal children (243 boys, mean 5.8 years) who visited at age 6 were included in this study. Serum concentrations of free thyro...

Background: Retinol binding protein 4 (RBP4) and adiponectin are known to be related with insulin resistance and type 2 diabetes.Objective and hypotheses: This study was aimed at investigating (RBP4) and adiponectin secretion in obese Korean children and adolescents with newly diagnosed type 2 diabetes (T2DM).Method: Nine obese children and adolescents with newly diagnosed T2DM (DM group) and ten obese age-matched subjects without ...

Objective: The role of incretins in type 2 diabetes (T2D) is controversial. This study investigated the association between incretin levels in obese Korean children and adolescents with T2D.Patients and methods: We performed a 2-h oral glucose tolerance test in obese children and adolescents with T2D and with normal glucose tolerance. Twelve obese children and adolescents with newly diagnosed T2D (DM group) and 12 obese age-matched subjects without T2D (...

The aim of this study was to investigate that exposure metabolites of phthalate one of the endocrine disruptors might be different in sex and might have influenced from obesity and insulin resistance in Korean children and adolescents. Nationwide data of 551 subjects aged 8-15 years (boys 281 and girls 270) who were included the study from 2010-2011. Subjects were grouped by sex and BMI percentile (normal: BMI<85p; overweight: 85P≤BMI<95p; obese: ≥95p). We...

Context: Diagnosis of non-chromosomal type disorders of sex development (DSD) has long been challenging. There is still no research on overview of a large Chinese DSD cohort.Objective: To determine the etiologic diagnosis through unbiased large-scale panel sequencing and whole-exome sequencing (WES) within a large Chinese DSD cohort.Design: Patients were recruited according to the ...

Objective: Patients with Turner syndrome (TS) have an increased risk of aortic dilatation (AD), which is associated with higher mortality. The diagnosis of AD in children is more difficult than that in adults. This study aimed to investigate the application of cardiovascular assessment criteria in diagnosing AD in Chinese children and adolescents with TS.Methods: In this retrospective study, a comprehensive cardiovascula...
