Tall stature is defined as a height greater than two standard deviations above the mean for gender and age. Most commonly tall stature is physiological and it is only rarely caused by an endocrine issue. Children whose heights fall within their expected adult height, and who are well, do not need further investigation.
A child’s mean expected adult height is calculated as follows:
- Boy: The mean of the parents’ heights plus 7 cm
- Girl: The mean of the parents’ heights minus 7cm
