[Follow-up study of former prenatally dystrophic newborn infants now 6 to 12 years old]

Area of Science:

• Pediatrics
• Developmental Psychology
• Neurology

Background:

• Small-for-date (SFD) infants represent a significant clinical concern.
• Early developmental trajectories and long-term outcomes for SFD children require further investigation.

Purpose of the Study:

• To assess the neurodevelopmental outcomes of small-for-date children up to 12 years of age.
• To identify factors influencing prognosis in this cohort.

Main Methods:

• Longitudinal follow-up of 58 small-for-date children aged 6-12 years.
• Assessment included neurological examinations, psychological testing (visuomotor perception), and electroencephalography (EEG).
• Children were categorized into three groups based on the number of abnormal findings (0, 1-2, or 3).

Main Results:

• 20-30% exhibited early motor and speech retardation; one-third had persistent weight and height deficits at 6-12 years.
• Mild neurological abnormalities, primarily affecting fine motor function, were noted in 17 children.
• Significant impairments in visuomotor perception (21 children) and EEG abnormalities (20 children) were observed.
• Group I (normal in all tests) comprised 23 children, Group II (1-2 abnormal findings) had 24, and Group III (all abnormal) had 9.
• Socioeconomic factors influenced follow-up results.

Conclusions:

• Small-for-date babies generally show encouraging outcomes in later childhood, with 40% being normal and most others having mild abnormalities.
• Prognosis may be improved by interventions such as preterm delivery to mitigate intrauterine growth retardation.
