Objective:
To investigate the association of sociodemographic characteristics, gestational factors, and birth outcomes with developmental delay from the second year of life in late preterm (LPT) infants.
Method:
This study included 327 LPT infants from a cohort started in 2010. Developmental performance was assessed using the Bayley-III screening test. The covariates were obtained with questionnaires and from the maternity records. Hierarchical multiple logistic regression was used for analysis.
Results:
Smoking during pregnancy was associated with fine motor and cognitive delays (OR = 2.27, 95 %CI 1.05-4.93 and OR = 2.22, 95 %CI 1.05-4.68, respectively). Living without a partner (OR = 2.98, 95 %CI 1.36-6.52) and intrauterine growth restriction of the child (OR = 2.63, 95 %CI 1.32-5.24) were associated with fine motor delay and neonatal intensive care unit admission with cognitive delay (OR = 2.11, 95 %CI 1.01-4.44).
Conclusions:
These factors must be considered when implementing strategies for the diagnosis of possible developmental delays and when designing interventions for LPT children.
