Backgro.nd: Inadequate antenatal care, bo.h in co.erage and standard, has been linked with po.r pregnancy o.tco.es. In a reso.rce po.r setting, ho.e delivery is co.sidered very cheap, but the po.sible o.tco.e o. such pregnancies has been a subject o. interest. This study evaluated the asso.iatio. o. bo.king status with pregnancy o.tco.es. o.jectives: To.examine the facto.s that influence bo.king and impact o. the bo.king status o. pregnancy o.tco.es. Metho.s: This was a ho.pital-based pro.pective co.o.t study o. 240 (120 bo.ked and 120 un-bo.ked) pregnant mo.hers selected thro.gh systematic rando. sampling. The study was carried o.t at the Department o. o.stetrics and Gynaeco.o.y, Alex Ekwueme Federal University Teaching Ho.pital Abakaliki, Nigeria. Chi-square test, t-test and lo.istic regressio. were used fo. analysis. Results: The mean age o. the participants was 30.39 ± 5.05 years and 29.05 ± 6.36 years respectively fo. the bo.ked and unbo.ked. Marital status (o. = 6.35, 95% CI = 1.24 - 32.59), educatio.al status (o. = 36.40, 95% CI = 5.26-152.83), place o. residence (o. = 0.15, 95% CI = 0.06 - 0.41), partner’s suppo.t (o. = 0.05, 95% CI = 0.01 - 0.37), family suppo.t (o. = 0.03, 95% CI = 0.01 - 0.13), mo.e o. delivery (o. = 0.23, 95% CI = 0.12 - 0.46), APGAR sco.e in first minute (o. = 6.02, 95% CI = 2.45 - 14.83) and NBICU admissio. (o. = 3.75, 95% CI = 1.67 - 8.43) were asso.iated with bo.ked status. Ho.ever, being unmarried, nulliparity/grandmultiparity, lo. level o. educatio., blue co.ar jo.s, lo. inco.e, rural dwelling and po.r partner and po.r family suppo.t were asso.iated with the unbo.ked. The bo.ked parturients had a better perinatal o.tco.e co.pared the unbo.ked. Co.clusio./Reco.mendatio.: There was high prevalence o. o.erative deliveries, perinatal mo.bidity and mo.tality amo.g the unbo.ked mo.hers.
