Abstract

Objective: To investigate the influence of chronic stress on the course of pregnancy and labor of women with deficiency body mass.

Methods: The comparison analysis of the course of pregnancy and labor was carried out between women in group I and group II. 51 women in Tadjik Republic (in the period of 1991-93 years) with deficiency body mass (DBM) were observed during war time (group I) and 50 women with DBM were observed in D. O. Ott Institute of Obstetrics and Gynecology in 1998.

(Group II). The starting body mass (BM) before the pregnancy of women in both groups was compared in relation to Brock's index. The body mass of investigated women was reduced by 15% or more in respect to an ideal BM.

Results: The course of pregnancy at women with DBM in both groups was characterized by increased frequency of high risk abortion, anemia of the mothers, premature labor. Peculiarities during the course of pregnancy in conditions of chronic stress were more frequent (p<0,01) development of chronic placentae insufficiency in 39,2 ± 6,8%, labor of full-term children with below-average (<3000 g) body mass in 61,9 ± 10,6% in comparison to indexes of group II - 14,0 ± 4,9% and 25,0 ± 6,5% accordingly. The violation of hemodynamics in functional system mother-placenta-fetus (FSMPF) was noted in 68,7% mainly in material-placenta circulation in women with DBM.

Conclusion: Chronic stress in women with DBM, which was brought about by war activity, leads to an increase in frequency of labor of children with small body mass. This increase may be linked with violation of hemodynamics in FSMPF.
