Maternal factors of pre-eclampsia development

Study objective: to determine the most important maternal factors for the pre-eclampsia (PE) prediction, which are used in screening of women when registered for pregnancy. Materials and methods. A prospective cohort study included 91 pregnant women in their first trimester; study period 2018–2020. The main group included 56 (61.54%) women with a number of maternal factors for PE development, and 35 (38.46%) were healthy females in the control group. Subgroups of women formed for females with and without PE – 28.57% and 71.43%, respectively. Results. Statistically significant values in the study of maternal factors were observed between subgroups of patients with and without PE for body mass index (BMI) prior to pregnancy (26.83 ± 1.29 and 26.03 ± 1.05) and height of pregnant women (163.35 ± 1.26 cm and 167.23 ± 1.02 cm), p 35 years was associated with PE (p = 0.008). During IVF PE developed in combination with such factors as BMI 30 kg/m2 and the interval between pregnancies over 10 years, 1.1% females had no other factors. History of renal disease and the age >35 years had an impact on the PE development in patients with anti-phospholipid syndrome. Analysis of the odds ratio of the isolated maternal factor showed the following indicators: PE during previous pregnancy – 6, multiple pregnancy – 2.56, anti-phospholipid syndrome – 2.56, first pregnancy – 1.83, in vitro fertilization – 1.72, obesity >30 kg/m2 – 1.65, PE in the mother – 1.57, age >35 years – 1.08, history of renal disease – 1, interval between pregnancies >10 years – 0.77 and chronic hypertension – 0.18. Conclusion. Thorough monitoring of maternal risk factors for PE should focus on PE during previous pregnancy. The second position is occupied by multiple pregnancy and anti-phospholipid syndrome. PE risk is increased for a combination of factors, especially with chronic renal disease and/or elevated BMI
