[Clinical analysis of the relation between maternal body weight and high risk factors during pregnancy and delivery].

The incidence of pregnancy induced hypertension (PIH), prolonged pregnancy, prolonged labor, macrosomia and the rate of operative delivery were analysed in 76 overweight women and in 436 women with normal body weight admitted at the same period to the hospital. The results showed that the occurrence of risk factors mentioned above was significantly higher in the overweight group, particularly in those with excessive weight gain during pregnancy than that of normal weight group (P < 0.001-0.05). To reduce high risk pregnancy, operative delivery, perinatal mortality and morbidity in overweight women especially associated with excessive weight gain during pregnancy the importance of perinatal care with nutritional advice is evident.
