Insights
Infant development scores, including language and social-emotional skills, were significantly lower during pandemic social distancing. This study highlights the impact of isolation on early childhood development.
Area of Science:
- Pediatrics
- Developmental Psychology
- Public Health
Background:
- The COVID-19 pandemic introduced unprecedented social distancing measures globally.
- Understanding the impact of these measures on early childhood development is crucial for public health.
- Six-month-old infants represent a critical developmental stage sensitive to environmental changes.
Purpose of the Study:
- To compare the global development of six-month-old infants before and during pandemic-related social distancing.
- To identify specific developmental domains most affected by restrictive measures.
- To analyze the relationship between the severity of restrictions and infant development scores.
Main Methods:
- A cross-sectional nested study design was employed.
- Infants were assessed using the Griffiths Scales of Child Development (GSCD) between September 2019 and April 2021.
- Infants were categorized into pre-COVID and COVID groups based on evaluation dates and local restrictions.
Main Results:
- A total of 104 healthy, term-born infants were evaluated.
- Infants assessed during the pandemic (COVID group) showed significantly lower General Development Scores (GDS) compared to the pre-COVID group (p < 0.001).
- The language and personal-social-emotional subareas were most affected, with a trend of decreasing GDS correlating with increased restriction severity.
Conclusions:
- Pandemic-induced social distancing was associated with a reduction in infant development scores.
- Language and personal-social-emotional development appear particularly vulnerable to isolation.
- Further research is needed to inform public health policies for infants and families during prolonged isolation.
Abstract:
Objectives: The study aimed to assess and compare the global development in six-month-old infants before and during the pandemic restrictive social distancing measures. Methods: This cross-sectional nested study involved infants assessed through the Griffiths Scales of Child Development (GSCD) between September 2019 and April 2021. Infants were classified in a pre-COVID or a COVID group, considering the evaluation date and the restrictive measures in place. GSCD subscales and General Development Scores (GDS) were calculated and compared. Results: One hundred and four healthy term-born infants were evaluated. GDS in the COVID group (n:70; median: 94; IQR: 90-100) appeared significantly lower than in the pre-COVID group (n:34; median: 98; IQR: 97-103; p < 0.001). Language and personal-social-emotional subareas scores appeared the most affected. A decreasing trend of GDS along with the severity of restriction was observed. Conclusion: A reduction in infant development scores was observed during pandemic social distancing. Further studies are needed to systematize these findings and to address effective public health policies for infants and families during long-term forced isolation periods.

The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
