Z-Score Reference Values for Height in Turkish Children Aged 6 to 18 Years

Abstract

Objective: Standard deviation score or Z-score reference charts are used in some countries in preference to percentile charts and are considered as better tools in assessing children with measurements outside the accepted limits of normality. Growth data for Istanbul children have previously been reported as percentiles; hence, the aim of this study is to present these data in Z-score reference tables. Data on secular trend in height in Turkish children will also be presented.
