Choline Boost: Mom's Nutrition Linked to Child's IQ
22 Oct
Summary
- Prenatal choline supplementation improved children's IQ scores by eight points.
- Children of mothers receiving choline showed fewer signs of social withdrawal.
- Maternal education level correlated with study dropout rates and child IQ.
A study involving 206 pregnant women has revealed a potential link between prenatal choline intake and later childhood development. Women were randomly assigned to receive either choline supplements or a placebo from 16 weeks of pregnancy until delivery.
By age four, children in the choline group scored an average of 106 on an IQ test, compared to 98 in the placebo group. Researchers noted this difference, particularly in working memory and visual-spatial skills.
Furthermore, the study observed a significant reduction in social withdrawal signs among children exposed to choline prenatally. While 24% in the placebo group showed elevated social withdrawal, only 4% in the choline group did.
However, the study faced challenges, including a significant dropout rate, particularly among mothers with lower educational attainment. This raises questions about the generalizability of the findings, as maternal education is also linked to child IQ.
Additionally, the trial did not find clear improvements in attention and preliminary findings regarding autism-related behaviors were not statistically significant. Researchers emphasize the need for larger studies to confirm these results and explore optimal dosage and long-term effects.
