BackgroundMild to moderate intellectual disability affects 2.5% of the general
population and is associated with an increased risk of several
psychiatric disorders. Most cases are of unknown aetiology although
genetic factors have an important role.AimsTo investigate the role of obstetric and neonatal complications in the
aetiology of mild to moderate intellectual disability.MethodObstetric and neonatal complications recorded at the time of pregnancy
and delivery were compared between participants with mild to moderate
intellectual disability, age-matched siblings and unrelated controls
using logistic regression.ResultsAdmission to a special care baby unit and not being breastfed on
discharge were more common in people with mild to moderate intellectual
disability. Not being breastfed on discharge was also more common in
those with intellectual disability than unaffected siblings. Foetal
distress was more common among controls than among those with mild to
moderate intellectual disability.ConclusionsAdmission to a special care baby unit and not being breastfed on
discharge may be related to the aetiology of intellectual disability,
although the direction of this association is unclear.
