Hello and welcome to the Zero to Finals podcast. My name is Tom and in this episode I'm going to be

talking to you about short stature. And if you want to follow along with written notes on this topic,

you can follow along at zero to finals.com slash short stature or in the development section of the

zero to finals pediatrics book.

So let's get straight into it.

Short stature is defined as a height of more than two standard deviations

below the average height for their age and sex.

This is equivalent to being below the second centile.

A child's predicted height can be calculated based on their

parent's height, measured in centimeters. The formula is different for boys and girls. For boys,

the formula is the mother's height plus the father's height plus 14 centimeters divided by 2. For girls, it's the mother's height plus the father's height plus 14 centimeters divided by 2.

For girls, it's the mother's height plus the father's height minus 14 centimeters divided by 2.

So what you need to remember is for boys, you add 14 centimeters to the mother and father's height,

and for girls, you subtract 14 centimeters from the mother and father's height. and for girls, you'd subtract 14 centimetres from the mother and father's

height. Let's talk about causes. The potential causes of short stature are familial short stature,

congenital delay in growth and development, malnutrition, chronic diseases such as celiac disease, inflammatory bowel disease or congenital

heart disease, endocrine disorders such as hypothyroidism, genetic conditions such as down syndrome,

and skeletal dysplasia such as acondroplasia.

Let's talk in more detail about congenital delay in

growth in puberty. Congenital delay in growth in puberty, or CDGP, is considered a variation on normal

development. It leads to short stature in childhood when compared with peers, but normal height in adulthood.

Puberty is delayed and the growth spurt during puberty last longer, which means they ultimately
