Obstetric outcomes in an aboriginal community: a comparison with the surrounding rural area.
Antenatal, intranatal and postnatal features of all Aboriginal women who lived at Cherbourg Aboriginal Community and delivered during 1990, 1991 and 1992 were compared with all non-Aboriginal women in the same rural area who delivered at Kingaroy Base Hospital during 1991. Almost all the Aboriginal women also delivered at Kingaroy. The data for 146 Aboriginal and 139 non-Aboriginal women were taken from the hospital records. The Aboriginal women were generally younger at delivery (Aboriginal 35% younger than 20 years vs non-Aboriginal 12%), made their first antenatal visit later (Aboriginal 49% after 20 weeks vs non-Aboriginal 10%) and made fewer antenatal visits (Aboriginal 43% < 4 visits vs non-Aboriginal 2% < 4 visits). They were more likely to be anaemic (Aboriginal 65% < 110 g/L vs non-Aboriginal 13% < 110 g/L), have a sexually transmitted disease (STD; Aboriginal 13% vs non-Aboriginal 2%) and drink alcohol (Aboriginal 54% vs non-Aboriginal 32%). After making an allowance for repeat Caesarean sections, there was no significant difference in the proportion of abnormal deliveries, but birthweights of Aboriginal infants were lower. Postnatally, the only significant difference between the two groups was a lower incidence of jaundice in Aboriginal infants. Multifactorial analysis showed that birthweights were significantly decreased by primagravidy, alcohol intake and STD. It is likely that the effects of STD and alcohol on birthweight were due to associated lifestyle factors. When these factors were allowed for, ethnic background had no significant effect on birthweight.
