Purpose: Short sleep duration is associated with obesity. Urinary 6-sulfatoxymelatonin (6-OHMS), the principal metabolite of melatonin, is closely related with sleep. We evaluated the difference in urinary 6-OHMS levels between obese girls and normal weight girls, and the relationship of urinary 6-OHMS with other hormones regulating body weight and metabolism. Methods: A total of 79 girls (6.3 to 12.4 years) were included in this study, of whom 34 were obese; 15, overweight; and 30, normal-weight. We examined their pubertal status and bone age. Fasting serum levels of total ghrelin, leptin, insulin, and first morning urinary 6-OHMS were measured. Homeostatic model assessment-insulin resistance (HOMA-IR) was calculated from the fasting insulin and glucose levels. Results: There was no significant difference in the creatinine adjusted 6-OHMS levels between the obese girls and the control group. Urinary 6-OHMS did not show any correlations with body mass index (BMI), BMI percentile, total ghrelin, leptin, and HOMA-IR. Negative correlations were found between urinary 6-OHMS levels and chronological and bone ages. Conclusion: Our results suggest that melatonin production is not reduced consistently in obese girls.

This study examined the effects of parental control and children's autonomy on self-esteem, using a sample of 415 school-age children (208 boys and 207 girls) recruited in Seoul. Ordinary Least Square regressions revealed a variety of gender-based differences in the associations among these three variables. Boys with high maternal behavioral control had high levels of self-esteem, whereas girls under low paternal psychological and high behavioral control reported high levels of self-esteem. Boys with high maternal behavioral control and girls with high paternal behavioral control also reported high levels of autonomy. Autonomy was found to exert a positive impact on self-esteem for both boy and girls. Autonomy played a mediating role in the relationships between maternal behavioral control and self-esteem for boys, and between paternal behavioral control and self-esteem for girls. These findings highlight the differential influences of psychological control and behavioral control on autonomy and self-esteem, as well as the relative impact of the opposite sex parent on the development of autonomy and self-esteem in late childhood.

The purpose of this study was to identify the body proportions of girls in middle and high school who have been a major sales target of clothing manufacturers and thus to provide the basic information on the proportion of human body, which is essential for manufacturer to produce clothing and for individual consumers to select right apparels to wear and purchase. The subjects were 133 girls in middle school and 141 girls in high school. As measuring instruments, the Martin's anthropometer, tapelines, and belts for marking waistline were used. In order to analyze the data, t-test and factor analysis were used. The measurement of vertical distance between vertex and measuring points, showed a significant difference between the high school group and middle school group in every item. In the comparison of eight head proportion between the two groups, middle school students had 7.2 head proportion while girls in high school had 6.9 head proportion in detail. The factor analysis of major divided body parts of the two groups indicated that waist-hip and hip-crotch, constituting lower trunk together, vertex-apex nasi, and apex nasi-back neck point, constituting head together, back neck point-spina scapula and spina scapula-waist, constituting posterior of upper body together, and mentum-bust point and bust point-waist, constituting anterior of upper body together, were in inverse proportion.

Adolescent girls experience significant breast growth is a significant secondary sexual characteristic development; their breasts are clearly different from adults' in volume, location and shape. This study was designed to understand brassiere wearing conditions and practices of adolescent girls aged between 15 and 18, as well as to identify problems and solutions so that it can serve as basic guidelines to develop patterns and sizes for adolescent brassieres. This researcher first studied brassiere wearing conditions and size fitness of adolescent girls. We analyzed the 439 collected responses from an online survey. The survey questionnaires encompassed brassiere wearing conditions and practices, brassiere size awareness, brassiere design preference, and brassiere purchase behavior. The survey found that 55.8% of the responders did not accurately understand their brassiere sizes, and those who understood their size showed a higher satisfaction and less discomfort than those who did not. This study found a requirement to educate adolescent girls on how to select and wear the right-sized brassieres. It is also necessary to promote different brassiere designs for adolescent girls' size and body shape.

This research predicted the fit of the basic bodice patterns worn on adolescent girls' 3-dimensional scanned bodies. Six 3-dimensional scanned bodies were selected from the sixth Size Korea data. Each of them had good body posture and represented one of the three garment sizes: 79-160, 82-160, and 85-160. Experimental basic bodice patterns were drafted by three basic bodice pattern making methods. The fit of the basic bodice pattern was analyzed by the CLO 3D virtual clothing system. The results showed that the experimental basic bodice patterns did not fit well at the neck, shoulder, and back for adolescent girls. The fit of the basic bodice patterns varied by pattern making method or size. The basic bodice pattern A with the waist darts ending above the breast line showed the best fit among the three different types of experimental pattern. Among the three sizes 79-160, 82-160, and 85-120, size 79-160 basic bodice pattern showed the worst fit for adolescent girls. The results show that the placement and size of the bodice darts affect the basic bodice pattern fit. The basic bodice pattern making method of size 79-160 for adolescent girls should be studied in a future study.

The purpose of this study was to examine whether uniform reforming behavior in high school girls is related to body image distortion, and to obtain objective data to help in guiding students in the wearing of uniforms at school. 661 freshmen and junior girls at six high schools in Kwangju city responded to questionnaires. The data was analyzed by one-way ANOVA and Pearson’s product-moment correlations using the SPSS 12.0 program. According to their body satisfaction level, three groups (haggard distortion, normal, overweight distortion) were identified. The data showed that a few high school girls were unable to recognize their body types correctly. It also indicated that school uniform reforming behaviors in high school girls were not related to their body image or body satisfaction level. So, it seems that students need guidance in the building up of an objective body image and wearing uniforms to fit their body types.
