To investigate the influences of aryl hydrocarbon (AHR), cytochrome P450 (CYP1A1), epoxide hydrolase 1 (EPHX1), and glutathione S-transferase P1 (GSTP1) genetic polymorphisms on small-for-gestational-age (SGA) infants. This nested case-control study (126 cases and 381 controls) was based on a prospective cohort study in Shanxi Province, China. We collected the general information of subjects using questionnaire and identified their single nucleotide polymorphisms by the MassARRAY genotyping platform. The polymorphisms of CYP1A1 (rs4646421 and rs4646903) and EPHX1 (rs1051740) were significantly associated with SGA. Neonates of women with EPHX1 (rs1051740) and GSTP1 (rs1695) variant alleles were at a significantly increased risk of SGA compared with the reference group (OR = 5.26; 95% CI, 1.08–25.66), as were neonates of women with CYP1A1 (rs4646903) and EPHX1 (rs1051740) variant alleles (OR = 7.11; 95% CI, 1.55–32.62). The results of strata analysis by AHR (rs2282883 and rs17137566) showed that the associations between the polymorphisms of CYP1A1 (rs4646421 and rs4646903) EPHX1 (rs1051740), GSTP1 (rs1695) and SGA were of significance in women with variant heterozygous or homozygous genotype. CYP1A1 (rs4646421 and rs4646903), EPHX1 (rs1051740), and GSTP1 (rs1695) genetic variances might increase the risk of SGA. AHR (rs2282883 and rs17137566) resulted in estimated effects varying across strata on CYP1A1 (rs4646421 and rs4646903), EPHX1 (rs1051740), and GSTP1 (rs1695).
