Aim. To evaluate the effects of maternal pre-pregnancy body weight and excessive gestational weight gain (GWG) on the risk of different subtypes of preeclampsia (PE). Methods. A cohort study of 289 pregnant women: 41 with early-onset (less than 34 weeks) preeclampsia (EPE), 76 with late-onset (more than 34 weeks) preeclampsia (LPE) and 172 normotensive women (control). Associations between anthropometric indicators (pre-pregnancy BMI, GWG, fat mass in the 1st, 2nd, 3rd trimesters, on the 2–3rd day after birth) and risk of PE and its subtypes were evaluated. Results. Pre-pregnancy body weight (r = 0.36; р = 0.000) and BMI (r = 0.38; р = 0.000) moderately increased risk of PE. GWG had independent risk of developing PE (r = 0.46; р = 0.000). Women with excessive GWG had an increased risk of PE in normal BMI (RR = 2.2; р = 0.019), in overweigh (RR = 2.7; р = 0.028), in obese (ОР = 5.2; р = 0.000). The risk of developing preeclampsia increased in normal weight with GWG more than 500 g per week in the 2nd trimester (р = 0.000) and more than 400 g per week in the 3d trimester (р = 0.000), total GWG more than 16.5 kg increased risk of preeclampsia in 3.4-fold (ОР = 3.4; р = 0.001). Overweight and obesity had an increased risk of late-onset preeclampsia (RR = 4.9; р = 0.000). No association was found for early-onset preeclampsia (p > 0.050). Gestational metabolic disorders were independent risk of LPE: weekly GWG and the per cent of fat mass in normal weight pregnant women with LPE were significantly higher compared to the women with EPE and control. The per cent of fat mass in the 1st trimester in PPE (23.90 ± 4.40 %) exceeded control (20.50 ± 4.30 %; р = 0.003) and EPE (21.20 ± 3.65 %; р = 0.008) groups. Differences were aggravated during pregnancy (р < 0.050). Conclusions. Pre-pregnancy overweight and obesity, excessive GWG and gain of fatty mass were an independent risk of developing PE with synergistic negative effect. Pre-pregnancy and gestational lipid dismetabolism were associated with LPE. Our results suggested that no correlation between pre-pregnancy BMI, GWG, fatty mass and risk of EPE.
