Obstetric outcome of Bangladeshi women in east London.
OBJECTIVE
To study the obstetric outcome of women of Bangladeshi origin in comparison with the white caucasian population in East London.


METHODS
A retrospective study of 16718 pregnancies over a five year period (1987-1991).


METHODS
An East London teaching hospital district.


METHODS
Six thousand four hundred and sixty Bangladeshi women compared with 7592 white caucasian women.


METHODS
Maternal: antenatal complications; induction and augmentation rates; analgesia and anaesthesia; instrumental delivery and caesarean section rates; third stage complications. Fetal: gestation and weight at birth; perinatal mortality rates.


RESULTS
The following statistically significant findings were noted: Bangladeshi women had a longer reproductive age span and were of greater parity including grand multiparity. They suffered fewer antenatal complications except for gestational diabetes. They had lower induction rates and, among the parous group, lower augmentation rates. During labour they required less analgesia but more commonly had general anaesthesia for caesarean section deliveries. They required instrumental delivery less often but there was no difference in overall caesarean section rate for the two groups. However, overall Bangladeshi women had a lower elective caesarean section rate, although parous Bangladeshi women had a higher emergency section rate. In the third stage there were no differences in the complication rates for the nulliparous women, however the parous Bangladeshi women had a higher postpartum haemorrhage rate and a lower perineal repair rate consistent with their higher parity. Whilst preterm births were more common in Bangladeshi women, significant prematurity (less than 28 weeks gestation) was less common. Similarly, although Bangladeshi babies weighed less at birth, they had fewer babies weighing less than 1500 grammes. There was no statistically significant difference in the perinatal mortality rate between the two groups, being 8.1 per thousand births overall. Whilst there was a statistically insignificant decline in death rates over the five-year period, between the groups there was no consistent difference.


CONCLUSIONS
Pregnant Bangladeshi women in East London constitute a relatively high parity, low risk population who have less obstetric intervention and yet manage an equivalent (or better) perinatal outcome compared to their white caucasian neighbours.
