| OBJECTIVE The purpose of this investigation was to determine the somatotype components and somatotype characteristics of the Han nationality of Shandong Province.METHODS The sample consisted of 3512 healthy participants randomly including 2511 youths (7-19 years: 1258 boys, 1253 girls) and 1001 adults (20-88 years: 502 men, 499 women) living in Qingzhou and Linqu of Shandong Province and was divided into 80 specific sub-groups by sex, area and age. The Heath-Carter anthropometric so-matotyping method was used. The somatotype components and distributions was calculated and compared with T-test and analysis of variance to test differences among the somatotype means and the somatotype attitudinal distance (SAD).RESULTS The somatotypes means and the somatotype distributions and somatotype components varies with age. For the youths, the values of Endomorph and Ecto-morph increased at the age 7-11, while the values of Mesomorph decreased. Then, the values of Endomorph and Mesomorph increased at 12-18 and over 30 years old groups while those of Ectomorph decreased. For the urban boys, the mean somatotypes were changed from Central to Endomorph-Mesomorph while the rural boys, changed from Mesornorph-Ectomorph to Endomorph-Mesomorph; For the urban girls, the mean somatotypes were changed from Central to Balanced Endomorphy while the rural girls, changed from Balanced Ectomorph to Balanced Endomorphy. The mean somatotypes of the adults were stable over 30 in both sexes. The somatotype means were 3. 9-4. 3-2. 3, 4. 7-3. 3-2. 4, 4. 6-4. 9-1. 5 and 6. 0-4. 5-1. 0 in the males below the age of 30, the females below 30 , the males over the age of 30 and the females over 30, respectively. There were difference between the urban and rural samples in the same sex and age groups except 15 and 18 years old groups, but no difference in the adults. The differnce between the sexes were significant at 9 years old in urban youth and at 7 in ru-ral youth (P<0. 05), and the difference were more significant at 12 in urban youth and 13 in rural youth (P<0. 01), and the difference exists in all the adults.The difference in the somatotype mean were significant between 15 and 16 age groups in urban boys (P<0. 05), 17 and 18 in rural boys (P<0. 01), 12 and 13 in urban girls (P< 0. 05) , 14 and 15 in rural girls (P<0. 01). Also significant between 25 and 30 years old groups in both sexes and between 20 and 25 in urban females.Compared with the female (girls and adult women), the male (boys and adult men) had higher values of Me-somorph and lower values of the Ectomorph, the values of Endomorph were similar; compared with the rural samples, the urban samples had higher values Mesomorph and lower those of Ectomorph.CONCLUSION For the rural boys of Han of Shandong, the somatotypes were similar to Daur and the Han of Beijing. For the urban boys and all girls, the somatotype are similar to Mongolian, Daur, and Hungarian at the most age groups. For the male a-dults, the somatotypes were similar Mongolian, Canadian and American (northeast and midwest) ; while for the female adults, the somatotypes were similar to Mongolian, Oroqen, Ewenki and Daur. The economy influences somatotype, mainly Endomorph. |
