Insights
Maternal education level significantly impacts preterm infants' development. Higher maternal education is linked to better cognitive, language, and motor outcomes at 20 months corrected age.
Area of Science:
- Developmental Pediatrics
- Neonatology
- Public Health
Background:
- Preterm infants face developmental challenges.
- Maternal education level (MEL) is a potential socioeconomic factor influencing child development.
Purpose of the Study:
- To assess the influence of maternal education level (MEL) on cognitive, language, and motor development in preterm infants.
- To determine the relative impact of MEL on developmental outcomes at 20 months corrected age (CA).
Main Methods:
- 177 preterm infants born between 2008-2010 were evaluated at 20 months CA.
- Bayley Scales of Infant and Toddler Development-III was used for assessment.
- Multiple and linear regression analyses identified the impact of MEL on developmental scores.
Main Results:
- Maternal education level was the strongest predictor of cognitive, language, and motor scores.
- Higher MEL was associated with reduced odds of subnormal language index.
- Graduate-level maternal education correlated with significant increases in cognitive, motor, and language scores.
Conclusions:
- Maternal education level is a critical determinant of developmental outcomes in preterm infants at 20 months CA.
- Further research should explore interventions to mitigate the effects of low MEL on early childhood development.
Abstract:
Objective To evaluate the relative impact of maternal education level (MEL) on cognitive, language, and motor outcomes at 20 months' corrected age (CA) in preterm infants. Study Design A total of 177 preterm infants born between 2008 and 2010 were tested at 20 months' CA using the Bayley Scales of Infant and Toddler Development-III. Multiple regression analyses were done to determine the relative impact of MEL on cognitive, language, and motor scores. Results Infants born to mothers with high school MEL were 3.74 times more likely to have a subnormal motor index, while those born to mothers with some college and graduate school MEL had reduced odds (0.36 and 0.12, respectively) of having subnormal language index at 20 months. In linear regression, MEL was the strongest predictor of cognitive, language, and motor scores, and graduate school MEL was associated with increases in cognitive, motor, and language scores of 8.49, 8.23, and 15.74 points, respectively. Conclusions MEL is the most significant predictor of cognitive, language, and motor outcome at 20 months' CA in preterm infants. Further research is needed to evaluate if targeted interventions that focus on early childhood learning and parenting practices can ameliorate the impact of low MEL.
