The prevalence of obesity in children has steadily risen during recent years in developed countries. Child obesity has become a major concern to health providers since it has grown to epidemic proportions over the past few decades. This study was conducted to investigate the biochemical status, dietary habits and life styles according to the obesity degree among obese children residing in the Gyungbuk area. The subjects were 148 elementary school students (boy 103, girl 45) and classified as mildly obese (n = 56), moderately obese (n = 61) and severely obese (n = 31) by the obesity index. The average body weight and height increased significantly according to the obesity degree (P <0.05, P <0.001). Serum cholesterol concentration came under the normal level in all groups. Serum AST activity increased according to the obesity degree but it was not significant. Serum ALT activity increased according to the obesity degree (P <0.05). Dietary habit score was lower significantly according to the obesity degree (P <0.01). Life style of the subjects was significantly different for the level of 'healthy state (P <0.05)', 'body perception (P <0.01)', 'watching TV and video (P <0.05)', 'normal sleeping hour (P <0.05)' and 'degree of stress (P <0.05)' according to the obesity degree. A positive relationship between obesity index and blood pressure, ALT has been shown in the subjects. Obesity index and dietary habit scores were negatively associated. Therefore, these results suggest that a practical nutrition-exercise education program for the prevention of child obesity should be provided to elementary school children.

Pupose:Recently childhood obesity is increasing and has been accompanied by an increase in the prevalence of type 2 diabetes mellitus(DM) among children and adolescents. We evaluated insulin resistance and impaired glucose tolerance(IGT) in 48 obese children and adolescents. METHODS:All subjects underwent a two-hour oral glucose tolerance test(1.75 g of glucose per kg of body weight) and then glucose and insulin levels were measured. Insulin resistance was estimated by homeostatic model assessment, and betacell function was estimated by calculating the ratio between the changes in the insulin level and glucose level during the first 30 minutes after the ingestion of glucose. RESULTS:IGT was detected in 4.2% of the 24 obese children(4-10 years of age) and 20.8% of the 24 obese adolescents(11 to 18 years of age). Type 2 DM was identified in 8.3% in children and 29.2% in adolescent obesity. Insulin levels were markedly elevated after the glucose tolerance test in subjects with IGT but a little decreased in cases with DM. Those changes of insulin levels were not significant statistically. The insulinogenic index was decreased in IGT and DM group of childhood and adolescent obesity compared to normal glucose tolerance(NGT) but it was not significant statistically. Insulin resistance, which was evaluated with fasting insulin, QUICKI and HOMA-IR, was increased in childhood obesity compared with adolescent obesity and the HOMA-IR of adolescent IGT group was significantly higher compared with NGT group(P<0.05). CONCLUSION: IGT is highly prevalent among children and adolescents with obesity. IGT was associated with insulin resistance and hyperinsulinemia, while beta-cell function was still relatively preserved. Overt type 2 diabetes was linked to insulin resistance and to beta cell failure.

9.Reemergence of mumps.
Korean Journal of Pediatrics 2010;53(5):623-628
The mumps virus is a single-stranded, non-segmented, negative-sense RNA virus belonging to the Paramyxoviridae family. Mumps is characterized by bilateral or unilateral swelling of the parotid gland. Aseptic meningitis is a common complication, and orchitis is also common in adolescents and adult men. Diagnosis is based on clinical findings, but because of high vaccination coverage, clinical findings alone are not sufficient for diagnosis, and laboratory confirmation is needed. Mumps is preventable by vaccination, but despite high vaccination coverage, epidemics occur in several countries, including Korea. Many hypotheses are suggested for these phenomena. In this review, we investigate the reason for the epidemics, optimal methods of diagnosis, and surveillance of immunization status for the prevention of future epidemics.

PURPOSE: We investigated the change of antibody titer to measles, mumps and rubella according to age after vaccination. METHODS: The IgG antibody titers to measles, mumps and rubella were tested on the residual serum from patients aged 7-20 years old after routine laboratory testing in the hospital with informed consent from the parents. RESULTS: Antibody to measles was present in 275 cases out of 408 cases with a positive rate of 67.4%, the mean IgG titer was 2.77+/-1.18 Index. Antibody to mumps was present in 112 cases out of 408 cases with a positive rate of 27.5%, the mean IgG titer was 2.08+/-1.29 Index. Antibody to rubella was present in 367 cases out of 408 cases with a positive rate of 90.0%, the mean IgG titer was 60.46+/-63.47 IU/mL. CONCLUSION: It is important to maintain a high rate of vaccination coverage in order to prevent an outbreak of measles, mumps, or rubella. It is also important to stress the maintenance of vaccination records for further reference.
