Child care in infancy and cognitive performance until middle childhood in the millennium cohort study

Area of Science:

• Developmental Psychology
• Child Development
• Cognitive Science

Background:

• Early childhood education and care (ECEC) is a critical factor influencing child development.
• Understanding the long-term impact of different childcare types on cognitive outcomes is essential.
• Social selection and data limitations can complicate the analysis of childcare effects.

Purpose of the Study:

• To investigate the association between infant childcare and later cognitive development in a large British cohort.
• To examine if these associations differ based on maternal education level.
• To assess the persistence of childcare effects on cognition at ages 3, 5, and 7 years.

Main Methods:

• Utilized a British cohort of approximately 13,000 children.
• Employed propensity score matching and multiple imputation to control for social selection and missing data.
• Analyzed cognitive outcomes at ages 3, 5, and 7 years in relation to infant childcare (informal vs. center-based) at 9 months.

Main Results:

• Infant childcare attendance at 9 months was positively associated with cognitive outcomes at age 3 years, especially for children of mothers with low education.
• Center-based care was linked to better cognitive outcomes than informal care at ages 3 and 5 years, but this difference diminished by age 7.
• Advanced statistical methods (propensity score matching, multiple imputation) identified significant findings missed by traditional regression and complete-case analyses.

Conclusions:

• Early childcare experiences, particularly center-based care, can positively influence cognitive development in the preschool years for disadvantaged children.
• The cognitive benefits observed in early childhood may not be sustained into later school years.
• Robust statistical methodologies are crucial for accurately assessing the impact of childcare on child cognition, accounting for confounding factors.
