2 37 pBMI, lipids and BP during pregnancy Prepregnancy weight status Prepregnancy body mass index (pBMI) was based on height and weight as reported in the pregnancy questionnaire, completed with data from the pregnancy files. Two categories were formed based on the WHO guidelines: normal weight (<25 kg/m 2 ) and overweight (≥25 kg/m 2 ). 22 Early pregnancy lipid profile The non-fasting early pregnancy lipid profile consisted of triglycerides (TG), total cholesterol (TC), free fatty acids (FFA), apolipoprotein A1 (ApoA1) and apolipoprotein B (ApoB) and were derived from biochemical analysis. The method of lipid analyses is described in detail elsewhere. 10 Since lipid concentrations increase in the first half of pregnancy, lipid measurements were interpolated to 10 weeks of gestation using a linear regression model. 12 Figure 1.
