ABSTRACT
PIP: A new set of standard curves of birth weight for singleton pregnancies with gestational age dated by ultrasonography was generated for the British population. The source of data was a computerized obstetric database of 41,718 pregnancies delivered between 168 and 300 days' gestation, taken from 3 large maternity units in East Midlands, the Nottingham University and City Hospitals, and Derby City Hospital. There were significant differences between the birthweights of 37,336 babies of mothers of English-European origin (3357 gm), 1008 babies of Afro-Caribbean origin (3173 gm), and 1547 babies of Indian subcontinent origin (3096 gm). There were also significant differences between ethnic groups for gestational length, parity, maternal height, weight, and smoking. These differences were greater than smoking was controlled. The effect of smoking was dose-related: at 40 weeks' gestation mean birthweights were 3580 gm for nonsmokers, 3416 gm for 1-9 cigarettes daily, 3374 gm for 10-19 cigarettes daily, and 3377 gm, for over 20 cigarettes daily. About 30% of the European and Afro-Caribbean women smoker, but almost none of the east Indians did. As had been seen elsewhere, ultrasound dating showed a lower gestational age than did menstrual dating (276 vs. 279 days), a discrepancy that is most likely to be clinically relevant in postdate gestations. While ultrasound dating is much more accurate, ethnic origin must be taken into account when assessing individuals.
