Abstract
AIM: We examined maternal prepregnancy anthropometry and cord blood DNA methylation.
METHODS: Associations between maternal measures (i.e., weight, height, waist circumference, hip circumference, skinfolds, leptin) and methylation β-values at each CpG (measured by the Infinium MethylationEPIC BeadChip) were estimated among 391 singletons.
RESULTS: Total of 18% of mothers were obese (body mass index ≥ 30) and 27% centrally obese (waist-to-hip ratio ≥ 0.85). One Bonferroni significant CpG with respect to obesity (cg02975187) and two with central obesity (cg12053563, cg12549355) were identified (p < 6 × 10 -8). A suggestive association (p < 10 -6) was observed at SFRS8 with increasing body mass index. SFRS8 was previously identified with propensity for weight gain in adults.
CONCLUSION: While associations identified with multiple measures related to maternal adiposity suggest different pathways, methylation differences were small in magnitude.
