HIGH-RISK PREGNANCY: EFFECTIVENESS OF PERSONALIZED PREGRAVID PREPARATION AND POSITIVE PERINATAL EXPERIENCE

Abstract

Research objective: to study the possibilities of improving perinatal results by optimizing pergravid preparation in women with high perinatal risk. Materials and methods. The first stage - a cross-sectional study - consisted in determining the vitamin D (VD) status and assessing the course of pregnancy in 459 women in the II and III trimester; the second stage was a randomized controlled study of women with VD deficiency in group IIA (planning stage, 54 women) and IIB (I trimester, 60 women), who received the vitamin and mineral complex (VMC) Pregna-5 with a high calcitriol content and perinatal results were evaluated. VD in the blood was determined by the enzyme-linked immunosorbent assay. Results. VD level was optimal only in 30.7% of pregnant women (group ІА), in 69.3% of women its insufficiency or deficiency was found (group ІB). The frequency of threatened termination (9.9 vs. 45.6%; p < 0.01), preeclampsia (2.0 vs. 11%; p < 0.05), intrauterine growth retardation (7% only in group IIB, p < 0.01) was significantly higher against the background of BD deficiency. Normalization of the VD level (groups IIA and IIB) after VMC administration was observed within 1-3 months. Pregnancy complications value was higher in the group where the VMC was started in the first trimester: early gestosis (15 vs. 28.57%; p < 0.05), the threat of termination (22.2 vs. 36.7%; p < 0.05), bacterial vaginosis (7.4 vs. 31.7%; p < 0.05), placental dysfunction (18.5 vs. 40.0%; p <0.01), placental pathology in group IIB was detected 2-3 times more often. The differences between the preeclampsia (1.9 vs. 6.7%; p > 0.05) and anemia (16.6 vs. 28.3%; p > 0.05) were insignificant. Analysis of the childbirth results showed a significantly higher frequency of cesarean sections in group IIB (38.3 vs. 22.2%; p < 0.05), the average weight of newborns was less (3299.11 ± 128 g vs. 3643.24 ± 136 g; p < 0.01). The most effective was the VMC start at the stage of pregnancy planning (F = 13.35482; p = 0.000016); a significant difference was revealed in the course of pregnancy in the groups where VMC started in the first, second and third trimesters of pregnancy (Q = 4.67, p = 0.00458). Conclusions. Timely donation of VMC with a high content of cholecalciferol in women with high perinatal risk may lead to a positive course of pregnancy. Further research is required to obtain a convincing evidence base.
