Objectives: The purpose of this study was to examine the associations among self-rated health and socioeconomic status. Methods: Analyses were conducted based on cross-sectional data obtained from the Korea Youth Risk Behavior Web-based Survey. A total of 79,202 students aged 12 to 18 years participated in the study and there was a response rate of 95.5%. Separate logistic regression analyses were performed on each gender group based on a set of independent variables. Those being: the level of parental education level; family affluence scale; subjective household economic status; and subjective school achievement with SRH as the dependent variable. Results: Multivariate analyses revealed significant associations between each SES and adolescent SRH after controlling for other covariates. However, in the models that included all SES indicators, subjective household economic status and subjective school achievement remained significant in boys and girls. Conclusions: The findings demonstrated that subjective SES indicators are more closely related to adolescent SRH when compared with objective indicators.

Purpose: The prevalence of binge drinking has increased among Korean adolescents in recent years. The purpose of this study was to determine the influencing factors of adolescent binge drinking. Methods: This was a secondary analysis of data from the 14th Korea Youth Risk Behavior Survey. For the present analysis, 5,203 binge drinkers (girls who drank 3 or more glasses of soju and boys who drank 5 or more in average on one occasion in the last 30 days) and 4,464 non-binge drinkers were selected. Results: Compared with the adolescents who had no experience buying alcoholic beverages, the adolescents who responded that it was easy or uneasy to buy alcoholic drinks were more likely to be a binge drinker. Also, compared with never smokers, ex-smokers and current smokers were more likely to be a binge drinker. Binge drinking was positively associated with skipping breakfast, subjective health, and feelings of sadness or hopeless. Conclusion: The findings of this study may be useful in developing binge drinking prevention programs for adolescents.

The purpose of this study was to investigate the relation of social support and aggression of early adolescents. The subject were 220 adolescents aged 11 & 14 years, who were enrolled 11 child welfare facilities or 6 public schools(3 elementary & 3 middle schools) in Seoul. That is, 110 institutionalized(IA) & 110 middle class home-reared adolescent (HA)s were examined. They subjects were asked to complete the questionnaire on social support and aggression. According to the results, 1)IAs perceived less support from peers or adults and showed more aggressive behaviors than HAs. 2)Significant sex difference was observed in aggression. Girls showed lower level of aggression than boys. 3)Adolescents' aggression was significantly correlated with social support. The more support from friends, classmates, and parents HAs perceive, the less aggression they reported. Though support from peers was correlated significantly only with anger expression, support from parents was correlated significantly with all the components of aggression. And the more support from friends and classmates HAs perceive, the less aggression they reported. These findings implicate that social support is a important factor in preventing aggressive behaviors of early adolescents.

The main goal of this program is to build a healthy adolescent culture tv broadening the understanding of adolescents and recognition of the environment as well through the development of educational programs centering on the domains of peer relationships, intimacy in dating relationships and sex, leisure activities, and consumption life of adolescents. The program was carried out to 10 young boys and girls for two days/one night and the major findings of the effects of the program through a qualitative evaluation were as follows: First, the program provided adolescent with a proper opportunity to promote a sense of self-confidence through the self-reevaluation process. Secondly, the program provided adolescents with a chance to firmly recognize to become good friends with others though the enhancement of self-esteem, which helped them to build a healthy peer relationship. Thirdly, adolescents were able to promote their views on sex and sexual decision-making by acquiring a proper knowledge of intimacy in dating relationships and of sex, and by candidly expressing their own opinions on sex with instructors. Fourthly, the program provided adolescents with an opportunity to look back on their leisure life with family members which had been neglected thus far and to renew their recognition of active leisure activities. Fifthly, the program provided adolescents with a chance to reflect on their unplanned consumption life and to be firmly determined to refrain from impulsive purchasing and extravagance.

Objectives : This study examined the influence of socio-demographic, health-related, and oral health-related characteristics on adolescent DMFTs. Methods : The subjects in this study were 1,129 adolescents selected from the 6th national health and nutrition examination survey data. To determine the factors influencing dental caries, a regression analysis using a complex-sample generalized linear model was conducted after adjusting for confounding factors. Results : DMFTs were smaller among boys than girls, and smaller in the "13-15 age group" than in the "16-18 age group." In terms of household income, DMFTs were larger in the "lower," "lower-middle," and "upper-middle" income brackets than in the "upper" income bracket. DMFTs were smaller among adolescents with a history of smoking than those who had never smoked. Conclusions : In order to improve the oral health of adolescents, oral health-promotion programs should be provided for girls, high school students, students from low-income families, smokers, and those who consider themselves to have poor oral health.

Loneliness in adolescence was examined in relation to peer aggression /victimization and to parental attachment with sample of 426 eighth graders in a suburban city. The subjects rated themselves on questionnaires regarding attachment to parents, peer experiences, and loneliness. Peer aggression and victimization was also rated by peers. In both boys and girls, the more they were attached to parents, the less loneliness they experienced. The more aggression and victimization they experienced from peers, the more loneliness they experienced. Lonely adolescent girls had lower attachment to parents and higher self-rated victimization by peers.

Adolescent obesity has a high risk of developing into adult obesity and may cause many psychological problems. This paper aims at giving a mathematical model for the obesity of Korean adolescents and predicting how much the prevalence of obesity among adolescents will increase using real data. We estimate that the obesity rate of boys will increase until about 28 ~ 29% in 2025.

Multicultural scholarship in sport and exercise psychology should help us understand and apply cultural competencies for all to be physically active. In the present study, two Asian countries, Japan and Singapore, were chosen. The participation rate for physical activities among adolescent girls tends to be lower than that of boys in both countries. Thus, the purpose of the project was to gain knowledge and understanding about sociocultural factors that may explain adolescent girls' perceptions and behaviors toward sport, physical activity, and physical education (PE). A qualitative approach using semi-structured interviews with focus groups was used to understand meanings of physical activity among Buddhist Japanese, and Hindu Indians and Christian Chinese from Singapore. Each focus group consisted of four or five girls and female researchers. Based on the analysis, we created four themes which were "cultural identities", "Asian girls and sport/physical activities", "PE experiences", "motivation for future involvement". The Buddhist Japanese, Hindu Indian, and Christian Chinese participants each reported unique physical activity experiences, and all the participants were aware of how Asian culture may affect being physically active. Experiences of PE classes were similar but perceptions of their PE attire were different for Christian Chinese and Hindu Indian adolescent girls. Based on the results, the importance of nurturing cultural competencies and ways to encourage girls to be physically active throughout life were discussed.

Purpose: Hepcidin levels have previously been reported to be correlated with liver damage. However, the association between hepcidin levels and liver fibrosis in children with fatty liver disease remains unclear. This study therefore aimed to investigate the pathophysiology of fibrosis in children with fatty liver disease and its association with hepcidin levels. Methods: This retrospective case series included 12 boys aged 6-17 years who were diagnosed with nonalcoholic fatty liver disease (NAFLD) or nonalcoholic steatohepatitis (NASH) at the Tokyo Medical University Hospital. Sixteen liver biopsy samples from 12 subjects were analyzed. Serum hepcidin levels were assayed using enzyme-linked immunosorbent assay. Immunostaining for hepcidin was performed, and the samples were stratified by staining intensity. Results: Serum hepcidin levels were higher in pediatric NAFLD/NASH patients than in controls. Conversely, a significant inverse correlation was observed between hepcidin immunostaining and Brunt grade scores and between hepcidin scores and gamma-glutamyltranspeptidase, hyaluronic acid, and leukocyte levels. We observed inverse correlations with a high correlation coefficient of >0.4 between hepcidin immunostaining and aspartate aminotransferase, alanine aminotransferase, total bile acid, and platelet count. Conclusion: There was a significant inverse correlation between hepcidin immunoreactivity and fibrosis in pediatric NAFLD patients; however, serum hepcidin levels were significantly higher, suggesting that these patients experienced a reduction in the hepcidin-producing ability of the liver in response to iron levels, leading to subsequent fibrosis. Therefore, hepcidin levels can be used as markers to identify the progression of fibrosis in patients with NAFLD.

Objectives : Autism is a well-known psychiatric disorder that is presumed to have a neural basis. To investigate the underlying neurofunctional abnormalities of autism, the authors performed single photon emission computed tomography (SPECT) on children with autism. Methods : Fifty-five children with untreated autism (47 boys and 8 girls, mean age=$50.6{\pm}20.28$ months) were selected from among the patients visiting the child and adolescent psychiatric clinic of Seoul National University Hospital. Psychiatrists had diagnosed the participants according to the DSM-IV criteria for autistic disorder and the Childhood Autism Rating Scale (CARS) criteria for a diagnosis of autism. All participants were examined using 99mTC-HMPAO Brain SPECT. Using statistical parametric mapping (SPM) analysis, we compared the participants' SPECT images to standardized SPECT images of normal children, which had been retrospectively selected by the authors, on a voxel by voxel basis. Voxels with a p-value less than .001 were considered to be significantly different. Results : The autistic group showed significant hypoperfusion in the right medial frontal gyrus, right precentral gyrus, and left precuneus gyrus. In addition, they showed no significant hyperperfusion areas when compared to the control group. Conclusion : The findings of hypoperfusion in the medial-frontal lobe and precuneus are accord with hemodynamic abnormalities that have been already reported. Therefore, these findings are compatible with the recently suggested "theory of mind" hypothesis and the disturbances in attention shifting that have been observed in autistic children.
