Short stature (SS) is defined as height more than two standard
deviations below the mean for age and gender. SS could be a result
of organic or non-organic causes. Organic causes include: endocrine
abnormalities, bone lesions, intrauterine growth retardation, chromosomal
abnormalities (Dawn syndrome, Russell-silver syndrome) or other causes.
Non-organic causes include: familial short stature,
malnutrition, constitutional delay of growth and adolescence. Around 2% of all
children present with SS. Boys tend to come to medical attention more
frequently than girls.
However, the percentage of girls with organic disease
significantly exceeded that of boys. Differences in height were more pronounced
around the age of 9 years. Sex was not associated with severity of short
stature.
