Purpose: Overweight can be defined by the body mass index (BMI) and is likely associated with an increased cardiovascular disease risk. However, waist circumference (WC), a central adiposity index, may be a better indicator of cardiovascular disease risk. Studies comparing the effects of BMI and WC on cardiovascular risk factors, such as high blood pressure (BP), are rare in adolescents. Methods: We analyzed the correlations of BMI and WC with BP in 3,363 Korean adolescents (aged 10-19 years), using data from the Korean National Health and Nutrition Examination Surveys (2009-2011). Results: Systolic BP (SBP) in both sexes and diastolic BP (DBP) in boys were higher in the high BMI (>85th percentile) and high WC (>90th percentile) groups. High BMI and high WC were positively correlated with high SBP (>90th percentile) in both sexes, and high DBP (>90th percentile), in boys. BMI maintained its positive associations with SBP, DBP, high SBP, and high DBP in the normal weight ($BMI{\leq}85th$ percentile) and overweight (BMI>85th percentile) groups in both boys and girls, as well as in all subjects of both sexes, even after adjustment for WC. However, WC did not correlate with SBP, DBP, high SBP, or high DBP after adjustment for BMI in any group in either sex. Conclusion: In Korean adolescents, BMI correlated better with BP and high BP levels than WC. Further, BMI was positively associated with BP and high BP in the normal weight group as well as in the overweight group.

Purpose: The aim of this study was to assess the body weight perception of adolescents and to investigate the difference between mental health and weight control behavior according to body weight perception. Methods: Study data on 12-18 years old adolescents with normal BMI was obtained from the 6th Korea National Health and Nutrition Examination Survey (2013-2015). Rao-Scott Chi-square test and ANOVA were used for the analysis. Results: The percentage of adolescents with a misperception of body weight was 43.3%, and their subjective health status (p=.013), stress perception (p=.001), and depression (p=.001) were worse than for adolescents who had the correct perception of their body weight. The percentage of adolescents who were trying to lose weight while perceiving their body weight as normal was 36.9%. Body weight control behavior had significant differences according to dietary intake (frequency of eating dinner (p=.015)), energy intake (p=.004), and carbohydrate intake (p<.001), but there was no significant difference according to exercise. Conclusion: Parents, school teachers, and nurses should make efforts to ensure that Korean adolescents perceive their body weight correctly, and prevent unhealthy weight control behaviors.

Peak bone mass is established predominately during childhood and adolescence. It is an important determinant of future resistance to osteoporosis and fractures to gain bone mass during growth. The issue of low bone density in children and adolescents has recently attracted much attention and the use of pediatric dual-energy X-ray absorptiometry (DXA) is increasing. The process of interpretation of pediatric DXA results is different from that of adults because normal bone mineral density (BMD) of children varies by age, body size, pubertal stage, skeletal maturation, sex, and ethnicity. Thus, an appropriate normal BMD Z-score reference value with Z-score should be used to detect and manage low BMD. Z-scores below -2.0 are generally considered a low BMD to pediatrician even though diagnoses of osteoporosis in children and adolescents are usually only made in the presence of at least one fragility fracture. This article will review the basic knowledge and practical guidelines on pediatric DXA based on the International Society for Clinical Densitometry (ISCD) Pediatric Official Positions. Also discussed are the characteristics of normal Korean children and adolescents with respect to BMD development. The objective of this review is to help pediatricians to understand when DXA will be useful and how to interpret pediatric DXA reports in the clinical practice for management of children with the potential to develop osteoporosis in adulthood.

The purpose of this study was to compare communication and mother-child interactions of reactive attachment disordered children with normal children. The subjects were 24 children and their mothers participated in this study'12 reactive attachment disordered children and mothers, 12 normal children and mothers. The mother and her child were brought into a p]lay room and the mother was instructed to play with her child as she normally would at home. The play situations were videotaped. Tapes were transcribed and transcribed data was analyzed with 13 mutually exclusive categories encompassing pragmatic functions represented in communication form the early stage of multiword speech in childhood. The tapes were analyzed with 10 behavioral mother-child interaction patterns. As the statistical method, t-test and correlation was calculated. The results of this study were as follows : 1) Reactive attachment disordered children used significantly fewer 'filler', 'information', 'requests', 'describes' and 'disscus self'. 2) Reactive attachment disordered children's mother used significantly fewer 'filler' and 'names'. 3) Reactive attachment disordered children used significantly more 'independent play', fewer 'intiates interaction', 'responsiveness' and 'answer' Reactive attachment disordered children's mother used more 'control play', 'observe' and fewer 'initiates interaction'. 4) Children's communication patterns were related lo mother·'s communication and mother-child interaction types. Children's 'filler', 'information requests', 'describes' and 'disscus self' were consistantly related to mother's 'filler' and 'names', (Children's 'filler', 'information requests', 'describes'. 'disscus self' and mother-child's intiates interaction 'responsivness' were significantly positively correlationed and 'independant play', 'control play', 'observation' were significantly negatively correlationed. The results of reveal that communication and mother-child interaction pattern of reactive attachment disordered group was different from normal group and children's communication pattern were influenced by mother's communication and interaction patterns.

This study were purposed to find out parental perceptions of child adjustment associated with parenting stress with autistic children and differences of parenting stress between autistic children's parents and normal children's. Subjects were 27 autistic children's parents, 28 normal children's, 4 teachers with autistic children. 'Scales were Parenting Stress Index(PSI), Eyberg Child Behavior Index(ECBI), Childhood Autism Rating Scale(CARS), Social Maturing Scale(SMS). The results of this study were as follows. 1) In total parenting stress, parents with autistic children had significantly higher scores than normal's. 2) In child domain of parenting stress, fathers with autistic children had significantly higher than mothers on the other components except Mood and Demandingness. 3) In parent domain of parenting stress, parents with autistic children had significantly higher than nomal's on Restrict of role, Attachment, Sense of Competence. All mothers of normal and autistic children had significantly higher than fathers on the other components except Repression. 4) In parenting perceptions associated with parenting stress level of autistic children's parents. Low level group perceived their children as higher adaptibility than teacher's evaluation and high level group perceived them as equal to teacher's.

Present study investigated the relationship between children's psychiatric disorders and their mothers' psychological problems. Ninety-one psychiatric outpatients from a children's hospital were classified into three diagnostic groups - internalizing symptom group(n=35), externalizing symptom group(n=35), and developmental disorder group(n=21) - based on their psychiatric problems. A normal control group was formed by matching on the age and education of mothers. Mothers' MMPI profiles which were classified into five types - normal, depression, anxiety disorder, somatization disorder, and personality disorder - were examined in relation with children's diagnoses. The profiles of the mothers in the normal control group were mostly normal, while depressive profiles were dominant among those of the clinical groups regardless of the children's diagnoses. Therefore, the data implied association between children's psychiatric problems and their mothers' psychological problems. A possibility of negative reciprocal interactions between children and their mothers was discussed. It was also suggested that further research need to examine the specific effects of children's psychiatric problems on the psychological adjustment of their mothers, as well as the effects of parental psychiatric problems on the adjustment of their offsprings.

Objectives: The objective of this study was to examine the effects of osmotic-controlled release oral delivery system methylphenidate on changes in regional cerebral blood flow (rCBF) in children with attention-deficit hyperactivity disorder (ADHD) using single photon emission computed tomography (SPECT). Methods: A total of 26 children with ADHD (21 boys, mean age: $9.2{\pm}2.05$ years old) were recruited. Each ADHD participant was examined for changes in rCBF using technetium-99m-hexamethylpropylene amine oxime brain SPECT before and after 8 weeks methylphenidate medication. Brain SPECT images of pediatric normal controls were selected retrospectively. SPECT images of ADHD children taken before medication were compared with those of pediatric normal controls and those taken after medication using statistical parametric mapping analysis on a voxel-wise basis. Results: Before methylphenidate medication, significantly decreased rCBF in the cerebellum and increased rCBF in the right precuneus, left anterior cingulate, right postcentral gyrus, right inferior parietal lobule and right precentral gyrus were observed in ADHD children compared to pediatric normal controls (p-value<.0005, uncorrected). After medication, we observed significant hypoperfusion in the left thalamus and left cerebellum compared to pediatric normal controls (p-value<.0005, uncorrected). In the comparison between before medication and after medication, there was significant hyperperfusion in the superior frontal gyrus and middle frontal gyrus and significant hypoperfusion in the right insula, right caudate, right middle frontal gyrus, left subcallosal gyrus, left claustrum, and left superior temporal gyrus after methylphenidate medication (p-value<.0005, uncorrected). Conclusion: This study supports dysfunctions of fronto-striatal structures and cerebellum in ADHD. We suggest that methylphenidate may have some effects on the frontal lobe, parietal lobe, and cerebellum in children with ADHD.

Objective : The aim of this study was to investigate the relationship between interoceptive awareness, sensory processing, and heart rate variability which reflects the function of the autonomic nervous system. Methods : Young adults completed the Adolescent/Adult Sensory Profile (AASP) and the Multidimensional Assessment of Interoceptive Awareness (MAIA) for sensory processing and interoceptive awareness, respectively. Heart rate was recorded using electrocardiograms during the resting period, and the standard deviation of normal-to-normal interval (SDNN) was extracted. The correlation between sensory sections of the AASP and subscales of the MAIA was analyzed, and the differences in touch and interoceptive awareness between groups with high and low SDNN were compared. Results : The touch of the AASP showed a relatively strong correlation with the subscales of the MAIA. Higher touch scores were associated with lower scores of not-worrying and attention regulation, but higher emotional awareness. The high SDNN group showed a tendency of higher interoceptive awareness compared to the low SDNN group. Conclusion : This study demonstrated the tactile processing has the relationship with interoceptive awareness and individuals with higher heart rate variability tend to have greater interoceptive awareness. This study provides information on interoceptive awareness, which is emphasized in recent occupational therapy and sensory integration practices, and deepens the understanding of neurophysiological mechanism of sensory integration.

To elucidate the biochemical etiology. 1) plasma dopemine-beta-hydroxylase activity was measured and 2) the correlation between age and DBH activity was examined in 30 Tourette's disorder, 19 chronic motor tic disorder, and 24 controls. The results are summarized as follows : 1) The mean plasma DBH activity in Tourette's disorder was significantly elevated compared to normal groups, but significant differences in DBH activity between Tourette's disorder and chronic motor tic disorder, and between chronic motor tic disorder and normal control group were not found. 2) In all three groups, the significant positive correlations between age and plasma DBH activity found. These findings support the hypothesis of a possible involvement of brain catecholamine dysfunction in the production of Tourette's disorders, and this dysfunction might be due to the increased dopaminergic and decreased noradrenergic function. Future research should be focused on the mechanism of functional abnormalities of DBH.

Objects：This study was carried out to develop the Korean form of Moral Development Inventory for Adolescents designed to assess the principled morality in adolescents. And the auther also intended to find the demographic variables that influence the moral development. Methods：The Korean form inventory was applied to 507 middle and high school adolescents, and retest was done in 42 second year middle school adolescents with 3 weeks interval. Together this inventory, short form of Rest moral development which had been proved its reliability and validity, were administered to the all subjects for concurrent validity. And then the author examined whether this inventory discriminates between conduct disorder patients, psychiatric controls and normal controls in the level of moral development. Results：Test-retest reliability and internal consistency were very satisfactory. Concurrent validity with this inventory was also high level. And conduct disorder patients were scored significant lower than psychiatric and normal controls in the level of principled morality. The mean PM scores did not show significant difference according to the variables such as sex, birth order and religion. But there was significant difference according to the educational level of mother and places. Conclusions：These results indicate that the Korean form of Moral Development Inventory is a reliable and valid rating inventory to assess the moral development level in Korean adolescents.
