Risk of Developmental Delay in Infants Born to Perinatal COVID-19-Positive Mothers at a Tertiary Care Hospital: A Cross-Sectional Study

Purpose: Prenatal and perinatal experiences of the mother are known to influence infant development. Maternal exposure to coronavirus disease 2019 (COVID-19) during pregnancy has been associated with increased morbidity and mother-baby separation. However, the developmental outcomes of infants born to COVID-19-positive mothers remain unclear. This study represents an initial exploratory effort to assess the developmental risks faced by infants born to mothers who tested positive for COVID-19. Methods: This cross-sectional study involved telephonic interviews and developmental screenings of 45 infants, aged 9 to 15 months, who were born to perinatal COVID-19-positive mothers between July 2020 and May 2021. The Ages & Stages Questionnaire was used for the developmental assessment. The impacts of maternal, infant and separation-related factors on development were analyzed. Results: Within the study population, 28.8% (13 of 45 infants) presented with a risk of developmental delay. The gross motor and problem-solving domains were the most frequently impacted. Among the factors studied, prolonged separation period (exceeding 7 days), advanced maternal age, and gestational age (preterm birth) were associated with higher proportions of infants at risk of developmental delay; however, these associations were not statistically significant. Conclusion: This study suggests that infants born to mothers who tested positive for COVID-19 during the perinatal period face a risk of developmental delay. Factors such as maternal age, gestational age at birth, metabolic disease during pregnancy, and infant-mother separation could exacerbate this risk. Future research should prioritize objective assessments of development and long-term follow-up to monitor developmental outcomes in this population.
