This systematic review and meta-analysis examined the relationship between maternal choline intake during pregnancy and outcomes related to fetal brain development and child neurocognition.
Analysing 30 human studies published between 1997 and 2021, the researchers found that low maternal choline intake or circulating choline concentrations were associated with a higher risk of neural tube defects (NTDs) in newborns. Specifically, the pooled estimate indicated a 36% increased odds of NTDs among mothers with low choline levels.
Furthermore, interventional studies within the review demonstrated that higher maternal choline intake during the second half of pregnancy and early postnatal period (ranging from 550 mg up to 1 g/day) was safe and likely to have favourable effects on various domains of child neurocognition, including memory, attention, and visuospatial learning.
Despite some limitations in the available trials and observational studies, the findings suggest that increased maternal choline intake is associated with better neurodevelopmental outcomes in children. The authors advocate for updated choline intake recommendations during pregnancy and lactation, especially considering that many young women do not meet the current reference intake levels.
