Purpose : The adipocyte has traditionally been known as a reservoir for energy, but currently there is growing evidence that the adipocyte plays an important role in the pathogenesis of energy metabolism and homeostasis. Adipocytokine released from the adipocyte has been known to play a role in diabetes mellitus, coronary artery disease and other diseases related with obesity. The purpose... |
Purpose : Obesity is becoming a serious health problem in schoolage children and adolescents. There are several parameters to estimate obesity such as body mass index(BMI), skinfold thickness, obesity index and weight for height. Each parameter has some advantages and disadvantages. Bioelectrical impedance analysis(BIA) seems to be a simple, reproducible, objective and cost effective method for fat evaluation. But there... |

Methods : The survey was performed by a special questionnaire on 1,707 children at elementary schools from 1 to 30 July 2001 in Gwangju City. The prevalence of snoring, associated factors, and sleep... |
Purpose : The prevalence of obese children has recently increased. Obesity is known to be associated with complications such as hypertension, fatty liver, hyperlipidemia, and insulin resistance. L-carnitine is an essential cofactor for the transport of long chain fatty acids into mitochondria for β-oxidation. The purpose of this study is to measure serum free fatty acid and carnitine levels, and... |
Purpose : Obesity is known to be associated with hypertension, dyslipidemia, and fatty liver and is thought to be associated with increased levels of free fatty acids. One of the strategies for decreasing free fatty acid levels is stimulation of hepatic lipid oxidation with L-carnitine. Carnitine is an essential cofactor for transport of long-chain fatty acid into mitochondria for oxidation.... |
Purpose : Obesity is closely related to insulin resistance, compensatory hyperinsulinemia and dyslipidemia in adults. We identified the effect of obesity measured by BMI and insulin resistance on dyslipidemia in children and adolescents. Methods : The fasting serum insulin, glucose, total cholesterol, triglyceride, HDL- and LDL-cholesterol were measured and insulin resistance(HOMA-IR) was calculated in 35 children with simple obesity(age :... |
Purpose : The incidence of type 2 diabetes mellitus in children has been increasing worldwide recently, which is thought to be related to the increasing prevalence of obesity. We investigated to evaluate the incidence and the characteristics of type 2 diabetes mellitus in children and also analysed the relationship between intrauterine growth retardation and type 2 diabetes mellitus. Methods :... |
Purpose : The incidence of obesity has increased in Korea recently. Obesity leads to higher risks of hypertension, hyperlipidemia and insulin resistance. It also leads to risks of respiratory complications. This study was performed to see the effects of obesity on children's pulmonary functions and on developed bronchospasm after exercise loading according to their obesity degrees. Methods : 257 obese... |

Methods : We examined children aged 7 to 12 in the total number of 3,028 elementary school students consisting of 1,579 boys and 1,449 girls between 1994 and 1999. Obesity was defined as weight that exceeded the standard weight... |
Purpose : The product of the ob gene, leptin is an adipocyte specific hormone that might be involved in the regulation of food intake by the central neuroendocrine system. Recent studies reported that serum leptin concentrations were correlated with Body mass index(BMI) and other obesity measurements. The aims of this study were to evaluate leptin concentrations according to degree of... |
Purpose : Body composition by bioelectrical impedance analysis(BIA) is a very useful method of analysing body composition in many diseases. BIA is a simple, rapid, non-invasive and reproducible technique. There was no comparative analysis between obese and healthy children. A comparative analysis between obese and healthy children is needed to assess the effect of excercise and other interventions in the management of childhood obesity.... |
Purpose : The incidence of obese patients has increased recently in Korea. Obesity is associated with hypertension, hyperlipidemia, insulin resistance, and fatty liver. Since recent investigators have revealed that not only fat accumulation but also fibrosis and nonspecific hepatitis can be found in the livers of obese children, fatty liver is currently considered as an important complication. The purpose of... |
Purpose : Obesity is known to be associated with complications such as hypertension, dyslipidemia, and insulin resistance. The importance of insulin resistance and hyperinsulinemia have been emphasized in obesity. Homocysteine is an emerging important risk factor for cardiovascular disease in adult, but there are less reports about homocysteine in children. Several risk factors such as blood pressure, lipid profiles, serum... |
Purpose : The increased prevalence of dyslipoproteinemia in obese children probably contributes to the high risk of cardiovascular disease associated with being overweight. The genetic makeup is possible one of the factors that influence the impact of obesity on lipid metabolism. A relation between apolipoprotein E(Apo E) polymorphism and lipid metabolism has been convincingly demonstrated in large population. The purpose... |
Purpose : The purpose of this study is to investigate whether there is a difference in leptin concentrations between those of children of normal weight and extremely obese children. Methods : We measured serum concentrations of leptin in 70 extremely obese subjects(7 to 12 years, 20 girls and 50 boys), whose serums had been frozen at -70℃. Height, weight, obesity index,... |
Purpose : Many authors have reported that obesity is a serious health problem in schoolage children and adolescents and recently obese children are increasing. Accurate diagnosis is needed to estimate the prevalence rate and trend of obesity. We studied body mass index(BMI) percentile for age and sex as a reliable and valid screening for adiposity. Methods : We measured... |
Purpose : It is known that insulin resistance and compensatory hyperinsulinemia from pancreatic islet cells to overcome insulin resistance could develop in children with simple obesity. When insulin resistance is aggravated by decompensation of high insulin secretion, obese children frequently progress to overt type 2 diabetes mellitus(DM). The purpose of the present study was to measure insulin sensitivity, glucose effectiveness,... |
