[Effect of the body weight of pregnant women on delivery and the birth state of the newborn].

Systematic and lately even rapid growth of the number of overweight people has been recently observed. In the economically well-developed countries fatness is the real problem of the contemporary man. The evaluation of the body weight of the pregnant women and its influence on the delivery and the birth state of the infants has been the aim of the study. 139 cases of pregnant women with physiological pregnancy have been analyzed. The pregnant women were divided into 4 groups according to the body weight at the early pregnancy which according to WHO criteria was expressed by the body mass index (BMI). The body mass of the delivering woman, date of delivery, way of delivering and probable delivering complications, performed obstetrical procedures, estimated blood loss of the delivering woman, sex, weight and length and the birth state of the infant according to the Apgar scale were evaluated prospectively. Analyzing the body mass of the women at the early pregnancy, underweight was stated at 55 women (39.57%), the proper body weight at 66 cases (47.48%), overweight at 12 cases (8.63%) and the fatness at 6 cases (4.32%). The average body mass index (BMI) at the early pregnancy was 21.63 kg/m2 and its increase during pregnancy was 5.95 kg/m2. It has been found out that the increase of body mass during pregnancy corresponds to the body weight before pregnancy and amounts to 16.22 kg on average. The study has shown more cases of surgical deliveries, greater intrapartum blood loss in the group of overweight and fat women, and greater harm to the vulva/vagina during delivery in the group of underweight women. The best delivery state of the babies has been found out in the group of women with the proper body weight.
