There have been studies about the relationship between zinc intake and pregnancy outcomes, but the results are inconsistent. We examined the association between maternal zinc intake and pregnancy outcomes in pregnant women enrolled in the Mothers and Children's Environmental Health cohort study. Dietary intake of midterm pregnancy was assessed by a 24‐hour recall method and pregnancy outcome data were collected from medical records. Total zinc intake was 8.4mg/day and that from animal‐sources was 3.4mg/day. A significantly difference in birth weight and height was associated with intakes of increasing amounts of zinc from animal‐source (P for trend <0.01 for birth weight and P for trend <0.001 for birth height, respectively) but not zinc from plant‐sources after adjustment for the covariates. Multiple regression analysis with covariates revealed that birth weight was associated with total zinc intake (P=0.001) and zinc intake from animal‐source (P=0.035), respectively. In conclusion, we found that group for animal‐source with good bioavailability is positively associated with birth weight and height.
