Zinc intake is essential for normal fetal growth and development. Many researchers reported that the molar ratio of phytate:zinc of a diet is a indexes of the zinc bioavailability. This study was examined the association between the molar ratio phytate:zinc and pregnancy outcomes in 918 women enrolled in the Mothers and Children's Environmental Health cohort study. Dietary intake of mid‐term pregnancy was assessed by a 24‐hour recall method and pregnancy outcome data were collected from medical records. The molar ratio of phytate: zinc was 7.7±3.8 (zinc intake, 8.4±3.5 mg/d; phytate intake, 626.0±331.8 mg/d) during pregnancy. Multiple regression analysis with covariates revealed that the molar ratio phytate:zinc was negatively associated with birth weight ( P =0.035) and birth height ( P =0.068). In conclusion, we found that the molar ratio of phytate:zinc is a important dietary factor for pregnancy outcomes. Our results suggest that animal foods, particularly rich sources of zinc, should be recommended for pregnant women to promote optimal fetal growth.
