Short stature in school-aged children
2
Growth charts based on data collected in different populations and time periods are key tools to assess children’s linear growth.
The recommended standard for our country is the Swiss one, developed in 1989, but it may be outdated because of the secular trend in height
Introduction
3
National growth charts are unavailable in numerous countries, including Romania.
Impaired growth is a major global public health issue , and its correct diagnosis is crucial to prompt timely intervention.
Introduction

2. Secondary growth disorders:A. MalnutritionB. Chronic diseaseC. Endocrine disorders such as:
a. Hypothyroidismb. Cushing sindromec. Pseudohypoparathyroidismd. Ricketse. IGF deficiency

To determine whether the longitudinal growth pattern of a child is normal, height should be compared to an appropriate reference population. [2]
The variation in linear growth charts appeared to be related both to the era of data collection and to true population differences.
Population differences could be related to environmental, socio-economical, genetic factors or differences in the extent of the secular trend. [2]
Discussions
15
There is an important difference in the incidence of short stature depending on the standards used.
The choice of reference charts substantially affects the clinical decision whether a child is considered short-for-age.
The low rate of agreement between the standards might show a source of error when defining short stature according to a certain standard and underlines the need for national references.
