Growth of height and development of pelvis in children during adolescent correlation with height of their parents

Abstract

To study the relationship between the development of pelvis in children during adolescent and the height of their parents, 95 boys and 104 girls of 6-year-old were selected. Longitudinal study for external measurement of pelvis and height of the children for 12 years was undertaken. Height of their parents were examined by questionnnaire. The results were as follows: 1) When children were devided into three groups, according to their height, i. e., large (L), medium (M), and small (S), both height and pelvis in each group grew in the same proportion during the period studied. Height and body weight of the children at birth are correlated with the height of their parents. 2) When the children were devided into L and S groups according to their height at birth, height of parents in L was greater than that in S, and height and the size of pelvis in girls of L group are greater than those of S group up to the age of 12-14. 3) When the parents were devided into two groups (L and S) according to their height, positive correlation was observed between the development of hight and pelvis of girls and the height of their parents. Height and the size of pelvis of the children born from L parents were greater than those from S parents. 4) Multiple regression analysis also demonstrated the positive correlation between height of the parents and the growth of height of their girls till the age of 17, and development of pelvis till the age of 14. These results suggest that the development of pelvis in girls is closely related hereditarily to the physical factor of their parents. © 1988, The Showa University Society. All rights reserved.
