The purpose of this study was to investigate self-perception of health and body image, blood lipid profiles and nutrient intake of adolescents. The subjects were 686 adolescent boys (379 middle school students, 307 high school students) and 613 adolescent girls (272 middle school students, 341 high school students) in Incheon. This cross-sectional survey was conducted by a self-administered questionnaire. Fasting blood samples were obtained and analyzed for triglyceride, total cholesterol and LDL- and HDL-cholesterol. Nutrient intakes collected from 3 day-recalls were analyzed by the Computer Aided Nutritional Analysis Program. Statistical analysis was conducted using SPSS 10.0 program. Average age, height and weight of male middle school students were 13.8 years, 163.5cm, 56.0kg and those of male high school students were 16.5 years, 171.7cm, 64.3kg. In female, average age, height and weight of middle school students were 13.7 years, 157.1cm, 51.5kg and those of high school students were 16.6 years, 159.7cm, 56.8kg. Female middle school students perceived their health status significantly better compared to female high school students (p < 0.001). Female high school students perceived themselves significantly fatter compared to female middle school students (p < 0.05). Average TG level of female middle school students was significantly higher compared to female high school students (p < 0.01). Nutrient intakes of the male and female students except phosphorus were lower than the Korean RDA. Especially, calcium and iron intakes of male and female students were under the 65% of the Korean RDA. Therefore, proper nutrition education is required for Korean adolescents to encourage desirable food habits and maintain nutritional lipids status. (J Community Nutrition 5(1) : 3∼12, 2003)

Objectives : Internet became essential component in these days. This study primarily tried to find out the characteristics of high risk internet users through using the communication scale. Methods : We investigated levels of internet addiction using Internet Addiction Scale in 1,193 high school and middle school students. Participants were divided into 3 groups (high risk user group, potential risk user group, normal user group) according to the results from internet addiction scale. We additionally surveyed characteristics of internet use, and patterns of communication and Communication Scale based on Satir theory in 614 from 1,193 participants. Results : Boys showed higher tendencies for internet addiction than girls in internet addiction scale. There were significant differences in mean computer using time especially during weekends among 3 internet user groups. The distribution of communication types in each internet user group was similar and this finding coincided with previous study results. However high risk user group showed higher scores in each inadequate communication pattern such as placating, blaming, super-reasonable and irrelevant stance. Conclusion : These results suggest that adolescents who use internet in addictive patterns may have more problematic communication styles and these may be associated with poor interpersonal relationships.

Objectives : The K-ARS (Korean ADHD Rating Scale) is one of the most important assessment tool of attention-deficit hyperactivity disorder (ADHD) in Korea. in this study, we presented detailed normative data on the K-ARS for school-aged children in Seoul metropolitan area to put it to practical use. Methods : The subjects were 2,397 students(1,223 boys and 1,174 girls, aged 6-12) from 4 elementary schools in Seoul, and one caretaker of each child completed the K-ARS for parents. Children who showed high scores of the K-ARS for parents were screened, and 2 child psychiatrists interviewed them to make a clinical diagnosis. We compared the mean scores of the K-ARS for parents between ADHD and normal group, and examined the percentage of correct classification. Results : There were some differences in score of the K-ARS for parents according to sex and age, so we presented continuous normative data with T score and subdivided cut-off points for ADHD screening. Interviews with child psychiatrists using DSM-IV criteria were performed to test diagnostic validity, and the difference in every the K-ARS for parents index between ADHD and normal group was significant(p<.001). Using 3 different cut-of points(80th, 90th, 93rd percentage), the accuracies of ADHD correct classification were 67.9, 72.2, 71.1% and all 3 canonical discriminants were significant (p<.05) between ADHD and normal group. Conclusion : The normative data and cut-off points on the K-ARS for parents are useful in screening ADHD children in Seoul metropolitan area.

Objectives : The purpose of this study was to investigate the use of various treatment modalities including pharmacotherapy, educational-behavioral therapy, and complementary alternative treatment for children with mental retardation (MR) or autism spectrum disorder (ASD) in Korea. Methods : The sample consisted of 50 parents who have children with MR (N=28) or ASD (N=22) : 38 boys, 12 girls ; mean age 14.06 (4.14) years old. A questionnaire was composed of the experienced modality, duration, cost, satisfaction, etc. Results : According to the results, 56.0%, 100.0%, and 36.0% of children with MR or ASD have experienced pharmacological treatment, educational-behavioral therapy and complementary alternative medicine (CAM), respectively. Children who experienced educational-behavioral therapy and CAM experienced 3.52 kinds of education-behavioral therapy and 2.78 kinds of CAM, respectively. Monthly cost of pharmacological treatment was lowest among three modality categories. Regarding treatment satisfaction by parental report, the lowest score was recorded for CAM. Conclusion : Parents who have a child with MR or ASD are trying many treatment modalities and feeling the burden of their treatment.

Objective: The objective of this study was to assess serum, hair, and urinary magnesium (Mg) levels in children with attention-deficit/hyperactivity disorder (ADHD), autism spectrum disorder (ASD), and both ASD and ADHD to reveal potential interactive effects. Methods: A total of 148 boys aged 4-9 years old were enrolled in this study, including 44 children with ADHD, 40 pediatric patients with ASD, 32 patients with both ADHD and ASD, as well as 32 healthy neurotypical children. Hair, serum, and urinary Mg levels were assessed using inductively-coupled plasma mass spectrometry (ICP-MS). Laboratory quality control was performed using certified reference materials of human hair, plasma, and urine. Results: No significant group difference in serum Mg levels was observed. Mg content in hair was found to be reduced in children with ADHD and ADHD+ASD compared to that in healthy controls by 11% and 15%, respectively. Urinary Mg levels in children with ADHD+ASD exceeded the control, ADHD, and ASD values by 51, 76, and 65%, respectively. Factorial analysis revealed significant contribution of ADHD to hair and urinary Mg levels. Multiple regression analysis demonstrated that hair and urinary Mg levels were considered as significant predictors of neurodevelopmental disorder complexity. Conclusion: We propose that impaired Mg status may provide a link between ADHD and ASD.

Objectives: Prenatal cadmium (Cd) exposure may be associated with attention-deficit/hyperactivity disorder (ADHD) in children. Therefore, the objective of this study was to examine the relationship between Cd exposure during gestation and ADHD at 6 years of age. Methods: As part of an ongoing cohort study (the Environment and Development of Children study), 479 mother-child pairs from Seoul, Korea were included for analysis between 2008 and 2011. The whole blood concentration of Cd was analyzed using atomic absorption spectrophotometry. The parents were surveyed about ADHD behaviors in their children at age 6. Multivariable linear regression models were used to investigate the relationship between prenatal exposure to Cd and ADHD at 6 years of age. Results: Increased prenatal Cd concentrations were associated with increased scores for ADHD for girls, but not for boys, at age 6. A 2-fold increase in the prenatal Cd level was significantly associated with a 22.3% (95% confidence interval, 11.6 to 34.1) increase in ADHD in girls at 6 years of age, as indicated by the linear regression model. Conclusions: Our results identified significant associations between prenatal Cd exposure and ADHD scores in 6-year-old girls.

The main purpose of this study was to speculate how psychological state of adolescent students has changed their school uniform style. For the study, the distinctive characteristics during adolescence stage were theoretically examined. Through the examination, this study found four interests in fashions and school uniforms. For the purpose, this study conducted interviews with grade 2 students in a total of six coeducation secondary schools in Seoul, Gyeongki and Gwangju using a questionnaire. The survey period ranged from December 15 2008 to December 24 2008 and a total of 1196 were used for a final analysis. This study extracted factors as Principal Components Analysis and used Varimax for orthogonal rotation analysis. To measure confidence, it used Cronbach's a test to item internal consistency. For data analysis, it used SPSS WIN 12.0 and for hypothesis analysis, frequency analysis, cross analysis, independent t-test, and one-way ANOVA were conducted. For posterior analysis, it used Sheffe test. The results are as follows: First, the interests in fashion and school uniforms differed depending on their own tastes, but these interests were more influenced by environment around school. Secondly, the boy subjects were more aggressive towards repairs their uniforms than the girls, which suggested that boys had stronger desire to show themselves to others and more satisfaction from repairs their uniforms than the girls. Based on the results, this study concluded as follows: We should pay attention to preventing deformation in original design of school uniforms while expanding options to have variable designs or to change detailed part of design. So, there will be no additional uniform mending expense and financial loss to parents, and students will be more satisfied with their school uniforms.

Objects : This study was attempted to evaluate the body image and the self concept in high risk adolescents for eating disorders. Methods 589 middle school students were investigated with EAT(Eating Attitude Test) and BITE(Bulimic Investigatory Test Edinburgh) and Schematic Figures(Child/Adolescent Version) and Piers-Harris Self-Concept Scale. According to the score of EAT and BITE, three high risk groups(high EAT group, high BITE group, high EAT & BITE group) were identified. Three groups were examined in terms of sex, weight, self concept and body image. Each group was EAT group, BITE group, EAT & BITE group Results: The results of the study were as follows : 1) EAT & BITE group showed greatest body image distortion. 2) BITE group and EAT & BITE group showed lower score in self concept scale. 3) The majority of EAT group were boys, BITE group and EAT & BITE group were mostly girls. 4) All three high risk groups, especially Bin group, revealed overweight compared with normal control group. Conclusions : High BITE group and high EAT & BITE group could be considered as significantly high risk groups for eating disorders, showing overweight, severe body image distortion, and poor self concept. EAT score alone seemed not to discriminate high risk adolescents for eating disorders.

Objectives:The purpose of this study was to verify discriminant validity and the clinical cutoff score of Child Behavior Checklist 1.5-5 in the diagnosis of developmental delayed infants. Methods:The participants were screened by Denver II which includes 156 developmental delayed infants and 288 normal infants. Chi-squared test, t-test, ROC curve analysis, odds ratio analysis were performed on the data. Results:Only 47 items out of 99 items among the CBCL 1.5-5 of total groups, 36 items of boys and 48 items of girls, discriminated developmental delayed infants well. Discriminant validity was confirmed by mean differences on the subscales of Withdrawn, Sleep Problems, Attention Problems, Internalizing Problems, Externalizing Problems, Total Problems, DSM Pervasive Developmental Problems and DSM Attention Deficit/Hyperactivity Problems between the two groups. Additionally, ROC analyses demonstrated that Withdrawn, Attention Problems, Internalizing Problems, Total Behavior Problems and DSM Pervasive Developmental Problems significantly predicted developmental delayed infants compared to normal infants. Also, the clinical cutoff score criteria adopted in the Korean CBCL 1.5-5 for subscales of Withdrawn, Attention Problems, Internalizing Problems, Total Behavior Problems and DSM Pervasive Developmental Problems were shown to be valid. Conclusion:The subscales of Withdrawn, Attention Problems, Internalising Problems, Total Behavior Problems and DSM Pervasive Developmental Problems significantly discriminated in the diagnosis of developmental delayed infants well.

Objectives: The purpose of this study was to investigate the prevalence of sleep problems in Korean elementary school children and the differences in sleep problems elated to their school grade and gender. Methods : One public elementary school in Dae-gu, Korea as randomly selected. And, parents who agreed to participate this study were asked to complete a modified version of Tucson Children's Assessment of Sleep Apnea screening questionnaire (TuCASA). Results: The most common sleep problem was 'falling asleep in vehicle (44.2%)' and the prevalence rate of this problem differed by school grade. The prevalence rate of falling asleep while watching TV before 8 P.M. (8.0%), daytime fatigue (21.9%) and nocturnal enuresis during the past 6 months (5.3%) were significantly differed by school grade. The prevalence rate of falling asleep while doing home work, falling sleep during a lesson, snoring and bruxism were 12.6%, 1.0%, 26.7% and 13.2% respectively. Although these rates did not show any differences between grades, snoring as more in boys and daytime fatigue was more in girls. Conclusion: This study demonstrates that many elementary school children may have various sleep problems. Lower grade elementary schoolers had sleep problems which related to euro-developmental factors, whereas higher grade elementary schoolers had sleep problems related to sleep deprivation and stress. Finally, more female schooler showed signs of fatigue or sleepiness than male schoolers.
