title: Obstetric complications among Chinese parturients with extreme prepregnancy ponderal indices.
abstract: 9,208 patients who received antenatal care and underwent delivery at a teaching hospital in Hong Kong during 1984 and 1985 were divided into 3 groups of high, normal and low prepregnancy ponderal index. The characteristics of each group were analysed using a computer database. Statistically significant differences were found between the groups. Parturients with high ponderal indices tended to be older, of higher parity, had heavier babies and had increased incidences of gestational diabetes, prolonged gestation, induction of labour, failed induction, Caesarean section and puerperal pyrexia. Parturients with low ponderal indices had an increased incidence of intrapartum fetal distress and instrumental vaginal delivery. These results indicate that the maternal ponderal index in Chinese parturients is a useful indicator of at risk pregnancies.
