The growth of height has great stability. Under the same socio-economic conditions, the heritability of height is 0.75, that is to say, 75% of adult height depends on heredity, and only 25% depends on environment. However, heredity can only determine the potential of height growth, and whether this potential can be played correctly depends on various environmental conditions (such as nutrition, physical exercise, disease prevention, life law formulation, mental health, etc.). ). At present, the mature forecasting formulas are:
1. Use the height of parents to predict.
Heredity has a great influence on height. Children whose parents are tall are generally taller. Therefore, the adult height of children can be calculated by the following formula:
Adult height of son (cm) = [(father height+mother height) /2]× 1.08.
Daughter's adult height (cm) = (father's height × 0. +Mother's height) /2
So you can roughly calculate the height of your future child:
Adult height of son (cm) = [(+)/2 ]×1.08 = .2cm.
Adult height of daughter (cm) = (× 0. +)/2 = .cm。
Check the boyfriend's height = [(+)/2] ×1.08 =.18, with a difference of 3.82cm! It may be caused by malnutrition or other factors in his parents' childhood! He grew to cm, indicating that this formula is still reserved! Having a boy may grow to cm! Even girls are estimated to be more than cm! !
2. Use the child's age and height to make predictions.
According to the follow-up observation data, British scholar Tanner found that the height of children at all ages has the following relationship with the height of adults: 0.27 at birth, 0.67 at 0 years old, 0.75 at 2 years old, 0.79 at 3 years old, and the correlation value will not increase after 4 years old. Based on this, the following formula is designed:
Male adult height (cm) = 1.27× H3+54.9.
Adult height of female students (cm) = 1.29× H3+42.3.
(where H3 is the height measured at the age of 3)
Another scholar, Vic, believes that the height of most children at the age of 2 has the highest correlation with the height of adults, so his formula is:
Male adult height (cm) = 0.h2+0.a+37.69.
Adult height of female students (cm) = 0. H2+0。 A+25.63。
(where H2 is the height at the age of 2, and A is (father height+mother height) /2).
