Insights
Children with fetal alcohol syndrome (FAS) experience developmental delays comparable to preterm birth (PTB) with complications. Interestingly, PTB may positively moderate developmental outcomes in FAS by limiting alcohol exposure.
Area of Science:
- Pediatrics
- Neurodevelopmental Disorders
- Public Health
Background:
- Preterm birth (PTB) is associated with developmental handicaps in children.
- Fetal alcohol syndrome (FAS) frequently occurs in preterm infants, raising concerns about combined effects on development.
Purpose of the Study:
- To compare the developmental outcomes of children with PTB and FAS.
- To investigate the impact of PTB on developmental delays in children with FAS.
Main Methods:
- The Bayley Scales of Infant Development - Second Edition were used to assess mental (MDI) and psychomotor (PDI) development in 2-year-old children.
- Participants included PTB children with and without medical complications, and children with FAS, some of whom were also born preterm.
Main Results:
- Children with PTB and medical complications (PTBc+) and children with FAS exhibited poorer mental and motor development than PTB children without complications (PTBc-).
- FAS children born preterm demonstrated significantly better mental development than FAS children born at term, with no difference in motor development.
Conclusions:
- Children with FAS show developmental delays comparable to PTB children with medical complications.
- PTB does not appear to worsen developmental deficits in FAS; instead, it may offer a protective effect by reducing prenatal alcohol exposure duration.
Objective:
Children with preterm birth (PTB), particularly if medical complications after birth are recorded, are at risk of developmental handicaps. More than half of the children with fetal alcohol syndrome (FAS) are born preterm.
Methods:
Using the Bayley Scales of Infant Development - Second Edition, we assessed the mental (MDI) and psychomotor development (PDI) of children with PTB and children with FAS. PTB children without (PTB_c-, N=31) and with (PTB_c+, N=17) medical complications as well as children with FAS (N=30; N=10 preterm, N=14 in term; N=6 not known) were tested at the age of 2 years (PTB: M=25 months, SD=3 months; FAS: M=27 months, SD=6 months).
Results:
PTBc+ (MDI=85; PDI=80) as well as FAS (MDI=79; PDI=80) children show a poorer mental and motor development than PTBc- (MDI=99; PDI=92) children. FAS children with PTB show a significantly higher mental development (MDI=84) than FAS children born in term (MDI=75), while there are no differences concerning their motor development (PDI=79 in both groups).
Discussion:
The results demonstrate that children with FAS are as developmental delayed as PTBc+children. PTB itself, although frequently occurring in FAS, seems not to exacerbate the mental or motor development deficits in children with FAS. Quite the contrary, developmental delay in FAS children seems to be positively moderated by PTB, as being born preterm is cutting short the noxious intrauterine alcohol exposition of the child.
