Objective: To investigate whether the early-life overweight/obesity trajectory from ages 2, 4, to 8 affects insulin resistance (IR) in 8-year-old prepubertal children.Methods: From the Environment and Development of Children (EDC) cohort, 262 prepubertal children (147 boys and 115 girls) who visited Seoul National University Children’s Hospital for anthropometric measurements at ages 2, 4 and 8 were included. At ag...

Keywords: precocious puberty, COVID-19Background: Studies have reported an increase in precocious puberty (PP) cases during the COVID-19 pandemic, but there is inconsistency in the findings. Various influencing factors have been proposed to explain this surge. The present study aimed to investigate the PP trend following the pandemic, examine potential influencing factors, and investigate the dose-response relationship b...

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...

Background: 5α - reductase type 2 deficiency (5αRD) is an autosomal recessive hereditary disease which has an incidence of 11.2%–15.5% among population with 46, XY DSD (disorders of sex development).Objective: To study the growth pattern in Chinese pediatric patients with 5αRD.Subjects: Data were from 187 patients with 5αRD (age from 0–16 years old,with homozygous or compound heterozygous mutations in ...

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...

Background: Precocious puberty is common in boys occasionally in girls with beta human chorionic gonadotropin (β-hCG)-secreting intracranial tumors, and is reported to be peripheral precocious puberty exclusively.Object: To described a girl with intracranial β-hCG-secreting germ cell tumor（GCT） who presented with central precocious puberty（CPP）.Method:<...

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...
