Abstract
Answer D
New child growth charts are based on the World Health Organization (WHO) Child Growth Standards, which describe the optimal growth of healthy breast fed children. Previous UK growth charts were based on data from studies on breast- and formula-fed children, so do not reflect normal weight fluctuations of breast-fed infants in the first few weeks.
The new charts combine UK90 and WHO data.
These charts can be used to estimate a child's weight, and hence calculate drug doses in the absence of precise measurements.
