It had been accomplished an investigation upon the pregnancy and the birth of 335 women in labour with high (> or = 5) parity (grandmultimaras = GM), including 11 736 labour, taking place in the Clinic of Obstetrics of Pleven Medical University. Controllable group had been formed out of a 655 women in labour with a parity from 1 to 4. It had been used a questionnaire method. Higher in the main group was the frequency of a hypertension, placental pathology (pl. praevia, abruptio et retention placentae) and that of a transverse and oblique presentation of the foetus. Lower in GM was the frequency of the neonates with a very low birth weight < 1500 g (VLBW), the frequency of induction and stimulation of the labour act, and of episiotomy and ruptures of the perineum. We come to the conclusion about the low level of obstetric risk with GM when there was an accessible and a competent obstetric assistance.
对普罗夫迪夫医科大学妇产科诊所335名高胎次（≥5次，即多产孕妇=GM）的分娩妇女及其11736次分娩情况进行了调查。对照组由655名胎次为1至4次的分娩妇女组成。采用问卷调查法。主要组中高血压、胎盘病理情况（前置胎盘、胎盘早剥及胎盘滞留）以及胎儿横位和斜位的发生率较高。多产孕妇中出生体重极低（<1500g）的新生儿发生率、引产和催产的发生率以及会阴切开术和会阴破裂的发生率较低。我们得出结论，在有可及且专业的产科援助时，多产孕妇的产科风险水平较低。
