Insights
Infant regulatory problems like excessive crying and feeding issues can negatively impact cognitive development in preschool children. These early challenges predict later cognitive outcomes, especially in girls.
Area of Science:
- Developmental Psychology
- Pediatrics
- Neuroscience
Background:
- Infant regulatory problems, including excessive crying and feeding difficulties, are common concerns for parents.
- Understanding the long-term impact of these early challenges on child development is crucial for timely interventions.
Purpose of the Study:
- To determine if infant regulatory problems predict cognitive outcomes in at-risk preschool children.
- To investigate the influence of these problems while controlling for confounding factors like neonatal complications and psychosocial elements.
Main Methods:
- Prospective longitudinal study of 4427 children in Germany, assessed at neonatal, 5, 20, and 56 months.
- Regulatory problems assessed at 5 months; mental and cognitive development measured at 20 and 56 months, respectively.
- Structural equation modeling and ANOVA used to control for confounding variables.
Main Results:
- 22% of infants experienced crying or feeding problems at 5 months.
- Regulatory problems directly predicted lower cognition in girls at 56 months.
- In boys, the effect was mediated by delayed mental development at 20 months; shortened gestation, neonatal complications, and poor parent-infant relationships predicted regulatory problems and lower cognition.
Conclusions:
- Infant crying and feeding problems have a small but significant adverse effect on cognitive development.
- Early regulatory issues in infancy can have lasting implications for cognitive function.
Objective:
To investigate whether regulatory problems, i.e., crying and feeding problems in infants older than 3 months of age, predict cognitive outcome in preschool children born at risk even when controlled for confounding factors.
Methods:
A prospective longitudinal study of children born in a geographically defined area in Germany. N = 4427 children of 6705 eligible survivors (66%) participated at all 4 assessment points (neonatal, 5, 20, and 56 months of age). Excessive crying and feeding problems were assessed at 5 months. Mental development was measured with the Griffiths Scale at 20 months, and cognitive assessments were conducted at 56 months. Neonatal complications, neurological, and psychosocial factors were controlled as confounders in structural equation modeling and analyses of variance.
Results:
One in 5 infants suffered from single crying or feeding problems, and 2% had multiple regulatory problems, i.e., combined crying and feeding problems at 5 months. In girls, regulatory problems were directly predictive of lower cognition at 56 months, even when controlled for confounders, whereas in boys, the influence on cognition at 56 months was mediated by delayed mental development at 20 months. Both in boys and girls, shortened gestational age, neonatal neurological complications, and poor parent-infant relationship were predictive of regulatory problems at 5 months and lower cognition at 56 months.
Conclusion:
Excessive crying and feeding problems in infancy have a small but significant adverse effect on cognitive development.
