Introduction The study aimed to compare the sociodemographical characteristics, obstetrical complications and foetal outcome in delivered booked mothers and delivered unbooked mothers and to determine the correlation of maternal and perinatal outcomes.
Methods In a prospective study over a 22-month period, outcomes of pregnancies of women booked for antenatal care were compared with that of unbooked women, who delivered in our unit at the Wesley Guild Hospital, Nigeria.
Results 29 percent of the 1,154 deliveries in the study period comprised unbooked mothers. Compared with booked mothers, unbooked mothers had a higher tendency to be younger (29.3 +/- 6.08 vs. 31.12 +/- 4.80; p-value is less than 0.001), unmarried (9.2 percent vs. 1.8 percent; p-value is less than 0.01), with lower educational status (25.8 percent with postsecondary education vs. 58.7 percent; p-value is less than 0.01), lower social class (25.0 percent in upper class vs. 52.3 percent; p-value is less than 0.001) and with higher proportion of multipara (12.5 percent vs. 5.5 percent; p-value is less than 0.02), higher incidence of antepartum haemorrhage (odds-ratio [OR] 5.96, 95 percent confidence interval [CI] 2.53-14.29, p-value is less than 0.001), anaemia (OR 2.75, 95 percent CI 1.09-4.47, p-value is less than 0.001) and preeclampsia/eclampsia. Unbooked mothers were half as likely as booked mothers to deliver by spontaneous vaginal delivery (OR 0.45, 95 percent CI 0.29-0.71, p-value is less than 0.001) but were twice as likely to deliver preterm babies (OR 2.03, 95 percent CI 1.14-3.59, p-value is less than 0.009) and three times more likely to have babies with birth asphyxia. Perinatal and maternal mortalities were higher in unbooked mothers.
Conclusion The study showed a positive correlation between unbooked mothers and an increased risk of maternal and foetal adverse outcomes.
