Purpose: This study was done to identify contraceptive practices in adolescent girls in South Korea and predictors of contraceptive practices. Methods: The study sample included 743 girls who had experienced sexual activity. Using statistics from the 12th (2016) Korea Youth Risk Behavior Web-based Survey, hierarchical logistic regression analysis was conducted. Results: The contraceptive practice rate for adolescent girls was 34%. Contraceptive practice was associated with 'age at first intercourse' and 'sexual intercourse after drinking'. For adolescent girls who had early sexual initiation and drank alcohol before sexual intercourse there was a tendency to reduce the practice of contraception. Conclusion: It is necessary to provide practical sex education to improve the practice of contraception in these adolescents. In addition, adolescent girls should be encourage to delay their first intercourse. The results of this study can also be used to develop education interventions regarding healthy sexuality behaviour including the practice of contraception.

The prevalence of childhood and adolescent obesity has increased and exacerbated during the coronavirus disease 2019 pandemic, both in Korea and globally. Childhood and adolescent obesity poses significant risks for premature morbidity and mortality. The development of serious comorbidities depends not only on the duration of obesity but also on the age of onset. Obesity in children and adolescents affects almost all organ systems, including the endocrine, cardiovascular, gastrointestinal, reproductive, nervous, and immune systems. Obesity in children and adolescents affects growth, cognitive function, and psychosocial interactions during development, in addition to aggravating known adult comorbidities such as type 2 diabetes mellitus, hypertension, dyslipidemia, nonalcoholic fatty liver disease, obstructive sleep apnea, and cancer. Childhood and adolescent obesity are highly associated with increased cardiometabolic risk factors and prevalence of metabolic syndrome. The risk of cardiovascular and metabolic diseases in later life can be considerably decreased by even a small weight loss before the onset of puberty. Childhood and adolescent obesity is a disease that requires treatment and is associated with many comorbidities and disease burdens. Therefore, early detection and therapeutic intervention are crucial.

Improving mental health and reducing the burden of mental illness are complementary strategies which, along with the treatment and rehabilitation of people with mental disorders, significantly improve population health and well-being. A Institute of Medicine report describes a range of interventions for mental disorders that included treatment and maintenance, reserving the term "prevention" for efforts that occur before onset of a diagnosable disorder. Mental health problems affect 10-20% of children and adolescents worldwide. Despite their relevance as a leading cause of health-related disability and their long lasting consequences, the mental health needs of children and adolescents are neglected. Early intervention can help reduce the significant impacts that children and adolescents with serious mental health problems may experience. Screening is the first step in early intervention, recognizing emotional and behavioral problems and providing help at an early stage. It is essential to implement early intervention in a sensitive and ethical manner to avoid any of the negative outcomes.

The purpose of this study was to develop the educational program model for adolescent substance abusers in relation to preventive and rehabilitative aspects. This educational program model was developed based not only on the social support theory ecological-developmental approach and cognitive-behavioral approach but also on previous studies. This model can be used both for adolescent substance abusers in early stage and in recovery stage. The main contribution of this study is that adolescent abusers will recover effectively through practicing this educational program model.

This study purposed to classify the somatotype of early adolescent girls based on the physical characteristics. For this purpose, a total of 529 girls aged between 10 and 14 were measured and data were collected from 42 anthropometric measurements and 41 photographic measurements per a person. According to the results of classifying somatotype based of the factor analysis, 176 students ($33.3\%$) were type 1, which is short and thin. In students of this type, the breast did not develop, the belly was stuck out as in the body shape of latter childhood, and the contour of the body had not been formed yet. This somatotype was named Type A. Another 176 students ($33.3\%$) were type 2, which is tall and somewhat thin. In students of this type, the breast and the hip developed well, so the contour of the body was quite clear. This somatotype was named Type X. Lastly, 177 students ($33_4\%$) were type 3, which is fattest among the three types. In students of this type, the breast developed but the waist and the hip were not voluminous. This somatotype was named Type H.

The purpose of this study is to propose apparel sizing system for each body shape of early adolescent boys. The subjects of this study were 549 boys in the capital area. Their body shapes were classified based on 47 anthropometric measurements, 43 photographic measurements and 10 indexed measurements. The apparel sizing system was proposed for each body shape. For data analysis were performed descriptive statistics, correlation analysis and crosstabulation using SPSS Ver. 12. The control dimensions to propose apparel sizing system were stature and waist circumference for the lower garments. Intervals between sizes were 5cm for stature and irregular for waist circumference. For each type, $5{\sim}8$ sizes were proposed for lower garments. Reference measurements suggested fur lower garments were 7 items. This study is meaningful in that it proposed apparel sizing system for each type of body shape. The results of this study are expected to contribute to planning sizes according to the type of body shape and improving the fitness of ready-made clothes in apparel and school uniform manufacturers.

This study was performed to investigate the hand size growth of Korean adolescents boys. Subjects were between 14 and 19 years (n=352). We collected the right hand size data of 19 measurements from each subject using 3D hand scanner. The total 26 hand measurements were analyzed including seven calculated measurements. Subjects were divided into three age groups (early, middle and late). Their hand size were compared. The results showed that all hand length measurements were significantly difference among age groups. Adolescent boys hands were sharply grown at age 16 years old. The hand dimensions of middle age group were compared with twenties men (n=215). There were significant differences between two groups. The middle age adolescents' hands were shorter and thicker than twenties men. Subjects were also divided by weight and height. Weight and height was closely related to hand size. The heavier and taller subjects had the thicker hand. Their fingers were longer than others. The adolescent boys and twenties men who were taller than the twenties' average height (173.4cm) were compared. Twenties men's hands were longer and thinner than that of adolescent boys. These results imply that the male adolescent hands grow short and thick in the adolescent period. Fingers continuously grow up as a long and thin shape after adolescent period.

Purpose: The purpose of this study was to evaluate the effects of a school-based intervention program for middle school adolescent girls with depression. Methods: The study was a pretest-posttest repeated-measure design with a nonequivalent control group. Fifty eight students with depressive symptoms were recruited from two middle schools in Seoul, Korea. The data were collected from the intervention (n=30) and the comparison group (n=28). The research instrument was Reynolds Adolescent Depression Scale. Results: The intervention group greatly improved from baseline to 10 weeks and then saw a slight positive change between 10 and 13 weeks. Conclusion: The results of this research show that depression intervention programs are effective for young female adolescents. Thus the investigation has important school-based treatment implications, and should be integrated into school curriculums by school health nurses for early intervention of depressive symptoms in middle school adolescent girls.

Data from the National Longitudinal Study of Youth (NLSY) were used to examine factors related to adolescent behavior problems, smoking, and delinquency. This study focuses particularly on the factors in an adolescent s immediate environment such as family, school, peers, and neighborhood (i.e. the microsystems) for the identification, prevention, and early intervention of adolescent behavior problems, smoking, and delinquent behavior. Both African American and Caucasian American adolescents between the ages of 13 and 17 for whom data were available in the NLSY were included in this study (N=788). Results indicate that delinquent peer pressure and negative attitudes toward school are important determinants of behavior problems, smoking, and delinquency of American adolescents. Differences between African American and Caucasian American adolescents are highlighted.

Objectives: The aim of this study was to identify differential impacts on smoking and drinking behaviors according to early menarche. Methods: 31,277 Korean female adolescents who had undergone menarche were included. Among them, 1,822 participants(5.8%) who experienced menarche in elementary school under 4th grade were assigned to early menarche group and others were was assigned normal menarche group. Using 11th(2015) Korea Youth Risk Behavior Web-based Survey, logistic regression analysis was conducted. Results: Adjusted confounding variables were analyzed and it was found that both drinking and smoking behaviors were higher in early menarche group. The participants with early menarche showed higher risk of non-daily smoking(OR=1.39, 95%CI=1.18-1.63), light daily smoking(OR=1.64, 95%CI=1.14-2.35) and moderate-to-heavy daily smoking(OR=3.15, 95%CI=2.02-4.92). Also, in the drinking behaviors, the risk of light and heavy drinking was higher than those of normal menarche group. Conclusions: Finding of this study showed Early menarche adolescents were associated with heavy smoking and drinking behaviors compared to normal menarche. Further studies are needed more evaluations.
