Vitamin B12 intake during pregnancy linked to child speech development and intelligence quotient.

ABSTRACT:

Background

Nutrient deficiencies during pregnancy may affect offspring development. We aim to examine the association between prenatal vitamin B12 intake and children's cognitive development.

Methods

A total of 5151 mother-child pairs from the Czech part of ELSPAC study were included in the analysis. Dietary information was obtained during pregnancy using food frequency questionnaire. Parents reported on their child's speech and language development at 18 months, 3, 5 and 7 years. Intelligence quotient (IQ) was measured at 8 years in subcohort of 854 children.

Results

Children of mothers with higher vitamin B12 intake demonstrated higher scores in language (B = 0.20, 95% CI 0.06, 0.34) and talking and understanding (B = 2.39, 95% CI 0.97, 3.80) in a fully adjusted mod
