Menarche in girls is usually a sign of mid-to-late puberty, after which most girls enter a period of deceleration in height gain.
Parents will also find some changes, such as the child's body is getting fuller and fuller, and the amount of food is not as much as before, etc., which are all signals that the child's height development is slowing down.
So here comes the question:How much taller can a girl grow after menstruation? This article will cite a study from the Capital Institute of Pediatrics for analysis.
Capital Institute of Pediatrics:
How much more can you grow is highly correlated with bone age at menarche
In 2021, the Growth and Development Research Department of the Capital Institute of Pediatrics conducted a statistical analysis of the age at menarche and bone age of 694 girls aged 8 to 14 years.
Research data shows that:The average age of menarche for girls is 107 years old, the average bone age is 124 years oldThe average height at menarche is 1489cm。
Specifically, although the biological age span of girls at menarche is very large, ranging from 8 to 14 years old, it correspondsThe bone age is mostly 124～12.8 years old, the gap and volatility are not large.
This means,Compared with age, bone age is a reliable indicator of a girl's menarche time and future growth potential. The bone age of girls with early menarche will inevitably be earlier, and the bone age of girls with late menarche will inevitably lag behind.
Calculation formula:
At menarche, different bone ages correspond to ** lifetime height
Based on this study, the Capital Institute of Pediatrics believes that the lifetime height (PAH) of girls is mainly determined by the height and bone age at menarche, and gives a calculation formula:
**Lifetime height (cm) = 0868 Height (cm) 3754 bone age (years) +73677
For example, if a girl is 145cm tall at menarche and has a bone age of 12 years, then according to the formula, the lifetime height is 1545cm, the remaining growth space after menarche is 95cm。
And for the same height, if the bone age at menarche is 13 years old, then the **lifetime height will become 1507cm, the remaining growth space after menarche is only 57cm。
Statistics from the Capital Institute of Pediatrics statedThe bone age of girls at menarche is greater than 12 years, and the probability of remaining natural growth potential exceeding 10 cm is only 57%；Bone age greater than 12At the age of 5, the probability drops to 0%.
