Gestational age and birth weight variations in young children with language impairment at an early communication intervention clinic

Abstract

Background: South Africa presents with high preterm birth (PTB) and low birth weight (LBW) rates (14.17%). Numerous conditions characterised by language impairment are associated with LBW and/or PTB. Speech-language therapists may fail to identify older children whose language impairment may have originated from LBW and/or PTB. Objective: To describe the frequency of LBW and/or PTB, in comparison with full-term birth, and associated conditions in children at an early communication intervention (ECI) clinic. Methods: Retrospective data of 530 children aged 3–74 months were analysed, with 91.9% presenting with language impairment. Results: Almost 40% had LBW and/or PTB, and late PTB was the largest category. Factors associated with LBW and/or PTB were prenatal risks, including small-for-gestational age, perinatal risks, including caesarean section, and primary developmental conditions. Secondary language impairment was prevalent, associated with genetic conditions and global developmental delay. Conclusion: The frequency of LBW and/or PTB was unexpectedly high, drawing attention to the origins of language impairment in almost 40% of the caseload at the ECI clinic.
