Effects of intrauterine exposure to SARS-CoV-2 on infants’ development: a rapid review and meta-analysis
Abstract
Potential medium- and long-term neurodevelopmental sequelae of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection during pregnancy have not been ruled out. We aimed to systematically review and summarize the evidence regarding the effects of intrauterine exposure to SARS-CoV-2 on infant development and behavior. Scopus, PubMed, Web of Science, CINAHL, and PsycNet databases were searched for studies published up to February 6, 2023, investigating the effects of gestational SARS-CoV-2 on infant development and behavior. We performed narrative synthesis according to updated protocols. Studies using comparison groups and with the Ages and Stages Questionnaires-Third Edition (ASQ-3) scores available were included in a meta-analysis performed according to Cochrane protocols. We used the Newcastle–Ottawa Quality Assessment Scale to analyze the risk of bias. Heterogeneity was calculated using the I 2 statistic. The search identified 2,782 studies. After removing duplicates and applying the eligibility criteria, we performed a narrative synthesis of 10 included studies and a meta-analysis of three. There was no evidence of higher developmental delay rates in infants exposed to SARS-CoV-2 during pregnancy compared to non-exposed infants. However, the exposed infants scored lower than either the non-exposed children or pre-pandemic cohorts in some domains. Pooled results from the random-effects model indicated that SARS-CoV-2-exposed infants had lower scores on fine…
