摘要:We investigated the association between maternal zinc level during pregnancy and the risks of low birth weight (LBW) and small for gestational age (SGA) infants in a large population-based birth cohort study. In this study, 3187 pregnant women were recruited. For serum zinc level, 2940 pregnant women were sufficient (≥56 μg/dL) and 247 deficient ( RR : 3.48; 95% CI : 2.03, 5.96; P RR for LBW was 3.41 (95% CI : 1.97, 5.91; P RR : 1.98; 95% CI : 1.36, 2.88; P RR for SGA was 1.93 (95% CI : 1.32, 2.82; P
