This study aimed at determining the outcome of pregnancy in unbooked m
others with regard to maternal complications and foetal outcome. This
retrospective study was based on investigations of medical records of
467 unbooked mothers who presented for delivery at the Obstetrics Unit
at King Khalid University Hospital, Riyadh, during the period 1991 an
d 1992, and 415 booked mothers with regular clinic attendance selected
as controls. Data collected from the records included patients' socio
-demographic characteristics, past obstetric history, prevalence of pr
egnancy-related diseases, and data relating to labour, delivery, and f
oetal outcome. Chi-square test and Fisher's exact test were used for a
ssessing the statistical significance of the association between the v
arious factors which were investigated. The tendency for mothers to be
booked was found to be significantly associated with their age, occup
ation, parity, and gestational age at delivery. Booked and unbooked mo
thers did not differ significantly in relation to the mode of delivery
and foetal outcome, although the prevalence of previous complications
of pregnancy was generally lower among unbooked mothers. There was no
statistically significant association between the absence of antenata
l care and outcome of pregnancies, unbooked mothers had a higher propo
rtion of MICU admissions and dead babies compared with the controls. E
ducating the community about the benefits of receiving regular antenat
al care, even if at primary care level, may be of great importance in
improving the pregnancy outcome.
