Norm of Physical Measurement of Typical Developing Chinese Children in Hong Kong

Introduction: A pilot study to establish a norm of physical measurement for typically developing (TD) Chinese children in Hong Kong. Methods: To establish a norm of physical measurements for typical developing Chinese children, kindergarten and nurseries across Hong Kong were recruited between 2009 to 2011. Height, weight, head circumference, ear length, outer and inner canthi, interpupillary distance, philtrum, hand and foot length were measured using standard procedures in children of typical development at preschool and kindergarten age. Results: A norm of physical measurements was established from recruitment of 658 TD children aged 1 to 7 years old (mean age of 4.19 years). Discussion: Based on the results from this study we have successfully shown the continuing establishment of a norm of body physical measurements for Chinese children in Hong Kong. This norm is a valuable tool for future quantification and the detection of deviations in children with a wide range of developmental and genetic disorders. With the use of validated quantitative measures, this would aid paediatricians with the identification of dysmorphology and differentiating what is within or outside of normal range.
