Prevalence of Hypertension at Antenatal Booking and Delivery in Ibadan
Abstract
Objectives: We assessed the prevalence of hypertension at antenatal booking and delivery among pregnant patients at the University College Hospital, Ibadan, Nigeria in other to evolve a special management plan for the control of this disease among them.
Methods: Pregnant subjects attending the antenatal clinic of the University College Hospital, Ibadan were recruited consecutively into the study. They had repeated blood pressure measurements and were followed up from antenatal clinic registration till delivery.
Results: Four hundred and nine pregnant subjects were examined and recruited into the study at booking, but only 187 of them completed the study and delivered at UCH. The frequency of hypertension at booking was 9.8%, rising to 26.2% at delivery, a statistically significant difference (χ2 = 27.25; p < 0.001). The mean SBP (127.1 ± 19.9mmHg) and DBP (80.5 ± 13.0mmHg) after delivery among the subjects were significantly higher than at booking (SBP, 114.2 ± 2.1mmHg & DBP, 73.4 ± 24mmHg; p < 0.001)
Conclusion: Prevalence of hypertension as well as the mean SBP and DBP were significantly higher post partum than at booking among the subjects. Previous personal and family history of hypertension were strong determinants of hypertension in pregnancy in them. There was no correlation between parity and level of blood pressure.
