Objectives The purpose of this study was to find out the clinically reliable relationships between the Risser sign and chronological age, bone age, menarche, and adult height prediction (AHP) and to evidence the reliability of the Risser sign. Methods This study had been carried out with 50 children who had their growth checked in an oriental medical hospital from January 2015 to February 2017. We investigated Risser sign in AP X-rays with iliac crest, bone age, AHP for all 50 children and the timing of menarche from the 22 girls in the study subjects. We also investigated a correlation between the Risser stage and the other indicators to analyze statistical data. Results The mean chronological ages of Risser 1, 2, 3 and 4 were 11.2, 12.6, 14.4, and 15.5 years respectively for the boys and 10.8, 12.2, 13.8 and 14.8 years respectively for the girls. The mean bone ages of Risser 1, 2, 3 and 4 were 12.3, 13.6, 15.7 and 16.5 years respectively for the boys and 11.7, 13.8, 14.3 and 14.9 years respectively for the girls. We analyzed 22 girls' Risser stages in accordance with the duration from menarche. The result showed that in the first six months after menarche, all girls were in Risser 1 and 2; in the next six months, the girls were in Risser 2 on average; in the next 12 months, all girls were in Risser 3 and 4; after more than two years from menarche, all girls were in Risser 4. The mean remaining growth height of Risser 1, 2, 3 and 4 were 27.8, 17.3, 4.4 and 1.0 cm respectively for the boys and 14.5, 5.1, 3.1 and 1.1 cm respectively for the girls. The Risser stage was correlated strongly with chronological age (Spearman's rho=0.707 (boy), 0.841 (girl)), bone age (Spearman's rho=0.869 (boy), 0.875 (girl)), duration from menarche (Spearman's rho=0.909) and remaining growth height (Spearman's rho=-0.784 (boy), -0.878 (girl)). Conclusions This study showed that the Risser sign can be useful in assessing skeletal maturity and predicting remaining growth height based on the Risser stage and the other growth indicators.

The purpose of this study was to analyze the body measurements of boys and girls at puberty and to provide the fundamental data for pubescent apparel manufacturers to produce clothing that reflect their physical characteristics. A total of 549 boys and 529 girls aged between 10 and 14 were measured in the capital area from March 4 to April 3, 2004. Data were collected from 35 anthropometric items and 12 photographic items per a person. SPSS Ver. 12 program was used in data analysis including means, standard deviation, t-test and Duncan test. The main results of this study were as follows. They showed the significant difference of their growth in accordance with the increase of their ages. There were also the difference between boys and girls. As for height and length items, boys showed a slow growth at the age of $10{\sim}11\;and\;12{\sim}13$. Those at the age of $11{\sim}12\;and\;13{\sim}14$ showed rapid growth. That is, an active growth was followed by a slow growth and that phenomenon repeatedly occurred. On the other hand, girls showed remarkable growth at the age $10{\sim}11$ and the growth rate gradually slowed down afterward. Regarding circumference items, boys at the age of $11{\sim}12\;and\;13{\sim}14$ showed remarkable growth. This results showed that boys at the age of $11{\sim}12$ had vertical growth and horizontal growth at the same time and for those at the age of $13{\sim}14$, growth was more conspicuous in horizontal direction. Meanwhile, for girls, the growth rate was high at the age of $11{\sim}12$, somewhat later than the age of the growth of height and length. As for breadth-related items and depth-related items, for both sexes two items grew steadily throughout the ages, breadth-related items showed a higher growth rate than that of depth-related items. This study analyzed the body measurements of pubescent boys and girls and the results showed that, for boys, an active physical growth took place at the age of 13 according to previous studies, but the findings of this study suggested that the phenomenon now occurred at the age of $11{\sim}12$, which proved that physical growth took place earlier than before. Also, an active growth was followed by a slow growth. Girls at puberty showed remarkable growth of height at the age of $10{\sim}11$ that is consistent with previous studies and then showed horizontal growth at the age of around 12, having a voluminous body shape.

Protein malnutrition of children is one of the most serious nutritional deficiencies in developing country. Urea nitrogen excretion in ureotelic animals is the function most sensitive to dietary protein. The 24 hours excretion of creatinine in the urine of a given subject is remarkably constant from day to day. The creatinine excretion of different individuals of the same age and sex is also quite constant. Low ratios of urinary urea to creatinine are found children low protein intake. The foregiving world-wide investigations indicate that the urea nitrogen/creatinine ratios seems to be a good biochemical indicator to distinguish among group with different levels of protein intake. The purpose of this study is to evluate an indicator of protein intake on the elementary school children ranged from 6 to 8 years of age living in rural and urban areas. Each child measured for height and weight of body. weight measured by means of a plate from scale and height by a vertical measuring rod. Biochemical test were taken from a finger-tip and urine. Hemoglobin level in the blood was measured by cyanomethemoglobin method. From the urine samples, urea nitrogen and urea creatinie were determined by Folin-Wu method and: calculate the ratio. The following result were obtained: 1) Mean of the body weight and height in urban children(Seoul) was higher and heavier than rural children(Kyunggi, Kangwon). And 12% of boys, 18% of girls in Kyunggi and 25% of boys, 22% of girls in Kangwon area weight less than 80% of Korean Physical Standard weight level. 2) The mean hemoglobin values of boys and girls in Seoul are children were 13. 3g/100ml, 13.1g/100ml and the mean of hemoglobin values in Kyunggi 12.9g/100ml of boys, 12.4g/100ml of girls, and 12.4g/100ml of boys, 12.9g/100ml of girls in Kangwon children. It is found that 22% to 24% children inrural area (Kyunggi, Kangwon) had hemoglobin level less than 12g/100ml which means anemia. 3) The mean of hematocrit level of Seoul, boys and girls children were 33.5%, 34.1% and 33.4%, 33.1%, in Kyunggi area and 33.1%, 32.9% in Kangwon area. 4) Urea nitrogen/creatinine ratios in Seoul children were 9. 0, 10. 0 of boys and girls, the ratio were 8.2, 8.0 in Kyunggi boys and girls children, and 7.5 and 7.4 in Kangwon boys, girls children. Low-income rural and upper-income urban background large differences between two groups in the urea nitrogen/creatinine ratio(Seoul: Kangwon in male, female children. p<0.05, p<0.001). The urea nitrogen/creatinine ratio definetly seems to be a good indicator of the quantity of the protein intake. However, whether or not it is an indicator of the quality of the ingested protein ramains to be seen.

Objective : Hyperlipidemia and hypertension are well recognized risk factors of cerebrovascular disease. So it's very important to evaluate blood pressure and s-cholesterol in adolescence. Material and Methods : April 1999, we were requested health examinaion for high school students of a boys high school and a girls high school in Jeonbuk, Korea. The subjects were 360 students, boys were 317 and girls were 343. They were checked their height, body weight, blood pressure, and s-cholesterol. Results and Conclusion : The mean of systolic blood pressure of study subjects was $111.89{\pm}12.43mmHg$. In boys, it was $116.25{\pm}11.78mmHg$, and in girls, it was $107.87{\pm}11.64mmHg$. The mean of diastolic blood pressure of study subjects was $68.45{\pm}9.40mmHg$. In boys, it was $66.92{\pm}10.00mmHg$, and in girls it was $69.85{\pm}9.40mmHg$. Hypertensives were 18(5.68%) in boys, 10(2.92%) in girls. The mean of s-cholesterol of study subjects was $174.95{\pm}32.28mg/dL$. In boys, it was $178.91{\pm}34.51mg/dL$, and in girls, it was $171.29{\pm}29.66mg/dL$. Hypercholesterolemias were 91(28.71%) in boys, 39(11.37%) in girls. The mean of BMI of study subjects was $21.12{\pm}3.27kg/m2$. In boys, it was $21.05{\pm}3.26kg/m2$, and in girls, it was $21.18{\pm}3.29kg/m2$. Obese boys were 18(5.68%), obese girls were 13(3.79%). The mean of diastolic blood pressure in obese boys was significantly higher than that of normal boys(p=0.001, Mann-Whitney test). The mean of s-cholesterol in obese boys($BMI{\ge}274$) was significantly higher than that of normal boys.(P=0.26, Mann-Whitney test).

본 연구에서는 남, 여 중학생의 체형인식에 딱른 외모관리 행동의 실태를 파악하고 비교 분석하여 청소년의 긍정적인 신체이미지 형성의 바람직한 방향을 제시하고자 하였다 조사 대상자는 광주소재 남 여 공학 중학교 7곳의 2. 3학년에 재학중인 435명의 남, 여중학생이었다. 결과분석은 SPSS Package 12.0(Kr)을 활용하였다. 그 결과를 요약하면 다음과 같았다. 먼저, 남, 여중학생들은 실제체형보다 비만하게 인식하는 것뿐만 아니라 실제체형보다 수척하게 인식하는 경향도 컸다. 자신의 체형을 제대로 인식할 수 있는 교육이 필요하다고 본다. 둘째, 신체인식 요인과 외모관리행동의 상관관계를 살펴보면 남, 여 중학생 모두 비만인식에 대해 운동보다는 다이어트로 외모관리를 하는 경향을 보이는데 이것에 대한 적절한 지도가 필요하다고 생각된다. 셋째, 자신의 실제체형보다 수척하게 인식하는 수척왜곡 인식집단과 정상집단의 외모관리행동을 살펴보면 남중학생은 운동관리만 하고 여중학생은 운동관리만 하지 알았다. 서로 차별화된 교육이 필요하다고 생각된다. 넷째 비만왜곡인식집단은 남 여중학생 모두 다이어트관리를 하는 반면 신체보정관리나 운동관리를 하지 않는 경향을 보였다. 실제적으로 운동관리가 가장 필요하다고 인식해야할 집단이 다이어트에만 의존하는 경향은 시정이 꼭 필요하다고 생각된다. 이상과 같이 우리나라 남 여 중학생의 왜곡된 신체인식과 외모관리행동을 바로 잡기 위해서 정규 교과목인 가정과목을 통해 표준체형에 대한 교육이 이루어져야 할 것이며 자신의 실제체형을 올바르게 인식할 수 있도록 하는 지도가 병행되어야 할 것으로 생각된다.

Objectives The purpose of this study was to investigate correlation between short stature and obese degree. And we also wanted to know the characteristics of patients visited clinic in the name of 'short stature'. Methods Height, body weight, BMI, fat mass, lean body mass, percent body fat were taken intended for 236 patients in the name of short stature. To all the patient questionnaire for growth clinic was drawn up, and ultrasound scan was taken through calcaneous of the right foot. The patients were classified to three groups - short, average, tall group - according to relative position of mid-parental height. It was analysed that the differences between groups in obese degree. Also was investigated correlation between position of short stature and obese degree, and between obese degree and bony maturity. Results & Conclusion 1. The average ages of patients in the name of 'short stature' were $12.69{\pm}3.93$ years old in boys, $10.66{\pm}3.67$ years old in girls. And it seemed to be just before second rapid maturing period. 2. The average BMI were $20.58{\pm}4.07kg/m^2$ in boys, $18.65{\pm}2.85kg/m^2$ in girls, and average percent body fat were $21.99{\pm}7.35%$ in boys, $26.01{\pm}6.35%$ in girls. 3. The numbers of obese children were 34(31.2%) in boys, 19(14.9%) in girls on the basis of BMI. And the numbers were 39(35.8%) in boys, 53(41.7%) in girls on the basis of percent body fat. There was a big difference in case of girls. 4. The numbers of AG(average group) were 48(44.0%) in boys, 60(47.2%) in girls, the numbers of SG(short group) were 35(32.1%) in boys, 31(24.4%) in girls, and numbers of TG(tall group) were 26(23.9%) in boys, 35(27.6%) in girls. 5. There were no significant differences among the groups in BMI, lean body mass, fat mass, percent body fat. Only significant difference in DI(disease index). 6. There were no significant correlation between PH(percent height) and BMI, leanbody mass, fat mass, percent body fat. Only significant correlation in DI(disease index). 7. There were no significant differences between DA(difference between bone age and chronorogical age) and BMI, leanbody mass, percent body fat. Only significant correlation in fat mass.
