Physical growth of children treated for phenylketonuria.

The growth of 133 children participating in the Collaborative Study of Children Treated for Phenylketonuria (PKU) was compared to growth data from the National Center for Health Statistics (NCHS) to determine whether the growth patterns of the children with PKU were the same as those of unaffected children. Height and weight by age, and weight by height, were analysed for ages 2-10 years. Head circumference by age was analysed for ages 2-7 years.
