Effect of educational preparation on the accuracy of linear growth measurement in pediatric primary care practices: results of a multicenter nursing study.

Consistently monitoring a child's linear growth is one of the least invasive, most sensitive tools to identify normal physiologic functioning and a healthy lifestyle. However, studies, mostly from the United Kingdom, indicate that children are frequently measured incorrectly. Inaccurate linear measurements may result in some children having undetected growth disorders whereas others with normal growth being referred for costly, unwarranted specialty evaluations.
