  1. Maternal lipid concentrations at preconception, at 28 weeks gestation, and the calculated change in lipid concentration from preconception to 28 weeks are presented for the overall cohort and by BMI group (<25 v. ≥25 kg/m2), limited to n = 575 women with singleton birth between 22–43 weeks gestation and birthweight and maternal preconception BMI available. Mean (SD) presented for all lipids. P value for significant difference in lipid concentration or lipid change by BMI group (one-way ANOVA) is presented.
  2. BMI, body mass index; LDL-C, low-density lipoprotein cholesterol; HDL-C, high-density lipoprotein cholesterol.
