Maternal periconception serum vitamin B12 concentration and risk of preterm birth: a prospective cohort study
No evidence of associations was found between maternal vitamin B12 concentration and risk of preterm birth in a population with relatively sufficient vitamin B12 levels. Future studies in populations with varied baseline levels of vitamin B12 are needed to validate these findings across different populations and regions.
