Our findings suggest that maternal leptin concentration during pregnancy is not an accurate indicator of fetal growth. Cord serum leptin concentrations were lower than maternal serum concentrations and correlated significantly with birth weight.

Folate nutritional status of mothers in the later half of pregnancy assessed by plasma and erythrocyte folate and plasma tHcy concentrations had no impact on neurodevelopment of their children at age 5. It is unknown whether our findings in a low-socioeconomic population can be readily extrapolated to other populations.
