Very Low Birth Weight and Growth to Age 8 Years: I: Weight and Height

Abstract

We determined the heights and weights at ages 2, 5, and 8 years for the following three cohorts of children: group 1 with birth weights between 500 and 999 g; group 2 with birth weights between 1000 and 1499 g; and group 3 with birth weights more than 2500 g. By age 8 years, group 3 children were significantly heavier and taller than all children in groups 1 and 2 combined; group 1 children were significantly shorter than those in group 2, but their weights were similar. From ages 2 to 5 years, annual increments in weight and height were similar in all three groups; however, between ages 5 and 8 years, children in group 3 grew faster than those in groups 1 and 2 combined, and children in gro..
