RESUMEN

The purpose of this study was to investigate factors related to bone mineral contents (BMC) at os calcis of adolescents. The subjects were 604 students (327 boys and 277 girls) between 7th and 9th grade in Seoul, Korea. The mean age was 14.2 +/- 0.9 years. General characteristics were collected by a questionnaire, bone mineral contents (BMC) were measured in os calcis by Duel Energy X-ray Absorptiometry (PIXI, General Electronics, USA) and height and weight were measured by bioelectrical impedance analysis method (Inbody 4.0, Biospace Co. Ltd, Seoul, Korea). Mean BMC of os calsis were 2.241 g. Height (p < .0001), weight (p < .0001), BMC (p < .0001) of boys were higher than those of girls. Percent body fat of girls, however, was higher than that of boys (p < .0001). Anthropometric measurement, pocket money, sibling, experience of fracture, pubertal stage, intake of supplements, physical or outdoors activity, and eating habit had significant influence on BMC of boys. Anthropometric measurement, physical or outdoors activity, and eating habit had significant influence on BMC of girls. Multivariate regression with adjustment for sex and age showed that BMC was associated positively with height, BMI, frequency of regular activity, and intake of spinach or radish leaves (all p < 0.05), and negatively with percent body fat (p < .0001) and Korean traditional diet pattern (p = 0.01). On the basis of these results, it is recommended to develop nutrition education and physical activity program for adolescents to improve BMC and prevent osteoporosis.

RESUMEN

OBJECTIVES: The aim of this study was to evaluate the reliability and validity of the Korean Version of the Diagnostic Interview Schedule for Children Version IV(DISC-IV), a highly structured diagnostic interview used to assess more than 30 psychiatric disorders in children and adolescents. METHODS: A total of 91 study subjects, including 67 subjects who visited the child and adolescent psychiatry outpatient clinic at our institution and 24 community-based subjects, were assessed using the Korean Version of the DISCIV. Clinical diagnosis was used as a gold standard for the examination of the validity of the DISC-IV. Forty-four of the study subjects were randomly selected for test-retest reliability measurement. RESULTS: The validity of the Korean Version of the DISC-IV showed kappa values ranging from 0.25 to 0.40 in the clinical sample and 0.65 to 1.00 in the community sample. The sensitivities varied according to the diagnostic categories, but the specificities were excellent for all diagnostic entities. CONCLUSION: The Korean Version of the DISC-IV showed good reliability and validity in Korean children and adolescents. The Korean Version of the DISC-IV might be a useful tool for assessing psychiatric disorders in children and adolescents.
