In order to assess the physical growth pattern of Korean Youth, the authors measured the body height, body weight, chestgirth and sitting height of 40967 persons (24832 males and 16135 females) from primary schools, middle and high schools and colleges of metropolitan (urban) and rural areas, and calculated the mene, standard deviation, standard error and coefficient variance of the body weight chestgirth, sitting height and various pertinent index by body height to demonstrate the standard physical growth and development by body height of sex and age. The following conclusions were obtained. 1. Physical growth and development: Rapid growth of physical growth in terms of body height has been observed among males in the age $7{\sim}15$ and among female $7{\sim}13$. Growth in terms of body height turned out to be slower among students of higher age by both sexes. The age of cross over between to sexes is between 10 to 13 years where upon girls out grows boys. Maximum annual growth were upon girls out grows boys. Maximum annual growth were both of 6.16cm from 8 to 9 years old and 12 to 13 years old for boys and 7.2cm from 8 to 9 and 6.1cm from 9 to 10 for girls. This indicates that girls enter a rapidly growing stage 2 years earlier than boys. Meanwhile, prominent improvement in body height of national students over period of ten year was noticed. 2. The distribution status of body height by age: The distribution status of body height by age were as follows; 7 year of age: boys-30cm range of body height from 104.0cm to 133.9cm, girls-27cm from 104.0cm to 130.9cm 8 year of age: boys-30cm from 116.0 to 145.9cm girls-33cm from 113.0 to 145.9cm 9 year of age: boys-30cm from 116.0 to 145.9cm girls-33cm from 113.0 to 145.9cm 10 year of age: boys-39cm from 116.0 to 154.9cm girls-39cm from 119.0 to 157.9cm 11 year of age: boys-45cm from 119.0 to 163.9cm girls-39cm from 122.0 to 160.9cm 12 year of age: boys-45cm from 125.0 to 169.9cm girls-42cm from 125.0 to 166.9cm 13 year of age: boys-45cm from 128.0 to 172.9cm girls-42cm from 128.0 to 169.9cm 14 year of age: boys-48cm from 131.0 to 178.9cm girls-36cm from 134.0 to 169.9cm 15 year of age: boys-42cm from 137.0 to 181.9cm girls-33cm from 137.0 to 169.9cm 16 year of age: boys-39cm from 146.0 to 184.9cm girls-30cm from 143.0 to 172.9cm 17 year of age: boys-39cm from 146.0 to 184.9cm girls-27cm from 143.0 to 169.9cm 18 year of age: boys-36cm from 152.0 to 187.9cm girls-27cm from 146.0 to 172.9cm 19 year of age: boys-30cm from 155.0 to 184.9cm girls-24cm from 146.0 to 169.9cm 20 year of age: boys-24cm from 158.0 to 181.9cm girls-l8cm from 149.0 to 166.9cm 3. Standard values of body weight, chest-girth and sitting height by body height of age were found all age groups from 7 to 20 years old and listed in tables from3-a to 16-a. 4. Standard values of relative body weight, relative chestgirth and relative sitting height by body height of age were found all age groups from 7 to 20 years old and listed in tables from 3-b to 16-b. 5. Standard values of physical and nutritional indices (Rohrer index, Kaup index, Vervaeck index and Pelidisi index) by body height of age were found all age groups from 7 to 20 years old and listed in tables from 3-c to 16-c.

Objectives The purpose of this study is to evaluate the current growth via Growth indices, Obesity indices, Metabolic risk factors of Multicultural Families' Children in Dae-jeon area. Methods 5 to 12 year old children from 56 multicultural families were enrolled in this study, and were examined their bone age and body composition, and have received blood tests. Results 1. In Growth indices, average height percentile was $53.64{\pm}25.59%$. The AHP and MPH respectively, were converted into 20 years old adult height percentile, AHP of a girls was 40 percentile and MPH was 19 percentile, AHP of boys was 57 percentile and MPH was 21 percentile. 2. In Obesity indices, average of BMI pecentile was $44.16{\pm}29.52$; low-weight group (6 boys, 4 girls), normal-weight group (20 boys, 18 girls), over-weight group (8 girls). Average PWH was $100.51{\pm}15.66%$; low-weight group (9 boys, 5 girls), normal-weight group (14 boys, 15 girls), over-weight group (3 boys, 5 girls), obesity group (5 girls). 3. The results of the relationship between Growth indices and Obesity indices, 1) As RH percentile in boys was increased, skeletal maturity, AHP and AHP-MPH were also increased. Similarly, as RH percentile in girls was increased, skeletal maturity, AHP and AHP-MPH were also increased. 2) As skeletal maturity in boys was increased, BMI percentile was also increased. As skeletal maturity in girls was increased, AHP-MPH was decreased but had no significant differences. Conclusions Current growth of children in multicultural families was above the average when compared to that of average children in the same age. It was predicted that the boys' height were still above the average adult height, but the girls' height were below the average. Also this study showed that girls were more prone to be overweight than boys, thus requiring more intensive management and training in regards to eating habits and exercise.
