Objective: The present study aimed to evaluate the association of free thyroxine (FT4) and TSH with insulin resistance indices in euthyroid Korean children and adolescents using nationally representative data.Methods: A total of 259 children and adolescents were included in data from The Korean National Health and Nutrition Examination Survey 2015.Results: TSH levels were significantly positively associated with HOMA-IR (β...

Purpose: In recent years, there has been an increasing focus on thyroid function in pediatric obese patients, but no nationwide study evaluating the relationship between thyroid function and obesity has yet been conducted in Korea. We aimed to evaluate thyroid dysfunction in obese Korean children.Methods: We analyzed the association between obesity and thyroid hormone levels among 975 Korean boys and girls aged 10–18 years, who participated in the K...

Purpose: Vitamin D deficiency (VDD) is very common nowadays in children as well as in adults, probably due to decreased exposure to sunlight. COVID-19 pandemic resulted in school closure and decreased outdoor activity in children, which lead to lower chance for exposure to sunlight. It was reported that the higher level of visceral fat was associated with the lower vitamin D levels in children. The aim of this study is whether body mass index (BMI) affect seru...

Background: ALT-P1 (CJ-40002) is a long-acting recombinant growth hormone (GH) fused with NexP, which is a long-acting carrier developed by Alteogen Inc. NexP is a protein engineered recombinant alpha1 antitrypsin with further increased in vivo half-life without a native proteinase inhibitor activity. In non-clinical studies of cynomologus monkeys, the extended half-life of hGH-NexP has been successfully proved without side effects in high dose as 20 mg per kg dose.<p clas...

Background: The recent articles showed a kind of associations of the serum vitamin D levels and chronic diseases, for example, autoimmune diseases, vascular disorders, as well as malignancies. Also vitamin D deficiency impacts normal growth and maximal bone mineral accretion in puberty. Of pediatric population in Korea, the prevalence of cases of vitamin D deficiency and precocious puberty were continuously increasing nowadays.Objective and hypotheses: W...

Background: The most common single nucleotide polymorphism in the IGFBP3 promoter region occurs at position -202. This polymorphic variation occurs frequently and may influence GH responsiveness and somatic growth.Objective and hypotheses: This study aimed to assess the effects of IGFBP3 promoter polymorphism on growth in children.Method: Restriction fragment length polymorphism (RFLP)-based genotyping of the -202 single nucleotide...

Objectives: Non-high-density lipoprotein (HDL) cholesterol is an alternative method to assess dyslipidemia and is not required fasting. We aimed to assess the validity of non-HDL cholesterol for detecting dyslipidemia among Korean adolescents.Subjects and Methods: Data for 6,989 adolescents aged 10 to 19 years (3,684 boys and 3,305 girls), were obtained from the Korean National Health and Nutrition Examination Surveys du...

Objectives: Dyslipidemia begins and continues in youth and is a major risk factor for adult-onset cardiovascular disease. The aim of this study was to investigate the prevalence and trend of dyslipidemia in Korean youth and its trends for 10 years.Methods: Study subjects were Korean youth aged 10-18 years who participated in the Korea National Health and Nutrition Examination Survey (KNHANES). A total of 7,466 eligible p...

Background: As the human genome is further explored, multiple genetic anomalies at different loci are being found that confer varying degrees of predisposition to diabetes. MODY is the most common form of monogenic diabetes, accounting 2–5 percent of diabetes. Recently, we have found and reported three noble gene variants relating to MODY in Korean children (Shim et al, Horm Res Pediatr, 2015).Objective and hypotheses: This study was done to see the...

Background: Low bone mass during growth may increase risk of fracture. Adequate reference data for bone mineral density (BMD) are needed to identify adolescents with bone deficit.Objective and hypotheses: We aimed to provide normative values and reference curves for BMD in Korean adolescents and young adults.Method: Using the data from Korean Nutrition Health and Nutrition Examination Survey (KNHANES) in 2008–2011, a total of ...
