Premature Kids Don't Always Catch Up
Aug. 8, 2000 -- When a premature infant survives without obvious physical or mental disabilities, most parents breathe a sigh of relief, confident that the child will "catch up" to his or her peers by school age. But often, that is not the case. A new study shows that, even at age 10, these children have many more social, behavioral, and academic problems than children who were carried to term.
The study was designed to paint a complete picture of what a very premature child would be like at age 10, compared with a full-term child, in terms of school performance, socialization, and behavioral disorders such as ADHD. This information is increasingly important to parents and educators, as physicians are able to save much smaller and younger babies than ever before.
The researchers looked at 118 preterm children, born at 24 to 31 weeks, and compared them with 119 children who were full-term. (For the child to be considered full-term, mothers must deliver between 38 and 42 weeks.) What they found was a much bleaker picture than they had expected, Jeremie Rentas Barlow, MS, tells WebMD. Barlow conducted the study with others at the University of Syracuse (N.Y.), where she is a doctoral student in psychology; the study was presented at a recent meeting of the American Psychological Association.
The children were born from 1985 to 1986. Information on their progress was collected from parents, teachers, and psychologists when the children were 15 months old and again when they were two, four, seven, and 10 years old.
"We used to follow [premature children] until four and five and until early school age, and we thought that they had caught up. But now that we are following them longer into life, we are finding they are more impaired than we believed they were," she says.
Specifically, 61% of the children who were born prematurely scored lower on achievement tests or were designated as having special needs, compared with 23% of the children who were carried full-term. The number of premature children who were held back a grade in school was double that of the full-term children. In addition, ADHD was four to six times more common in the preterm group than in the general population, Barlow says.
