The single most significant factor affecting the adult height of a child is its genetics.

Inadequate nutrition, both in terms of total calories consumed and in terms of making sure all macro and micro nutrients are present in the diet, can certainly hinder growth. See our daily calories calculator. 2 Hormones. Issues with hormone levels, especially growth hormone or thyroid hormones can impact the end height in both directions. 3 Diseases. Health issues, for example coeliac disease or early arthritis play a negative role 4 Genetic conditions.
