Developmental delay in preterm infants during the first twelve months after birth and its risk factors.

Abstract

Background: Developmental delay in preterm infants in different geographical areas has different risk factors. The present research was a large study aiming to assess developmental delay in preterm infants during the first 12 months after birth and its risk factors in northwest Iran (with multiethnic texture).

Materials and methods: Eight hundred and seventy preterm infants (25 to 36 weeks; up to 12 months) were included in this descriptive-analytical study from the beginning of 2019 to the end of 2021 in northwest Iran by the convenient sampling method. Patients' basic and medical information was recorded in the data collection form, and the Ages and Stages Questionnaire (ASQ) was used to assess children's developmental status.

Results: The prevalence of developmental delay in this study was 26.4%. Regarding demographic characteristics such as age, height (at birth and one year of age), weight (at birth and one year of age), Apgar score (first and twentieth minutes), duration of ventilator connection, comorbidities and complications after birth, and breastfeeding during the first year of life, there was a statistically significant difference between the two groups of infants with and without developmental delay. Breastfeeding during the first 12 months after birth alone could have the power to predict developmental delay in preterm infants.

Conclusion: Breastfeeding in the first year of life is considered one of the most important predictors of normal development in preterm infants. Therefore, encouraging the parents of these infants to breastfeed their infants at birth can be a positive step in improving the quality of life of these infants in the future.
