Prevalence and Risk Factors of Placenta Previa in Saudi Arabia and Sudan 2016

This is a descriptive cross-sectional study conducted in Alshaikh Mohamed Ali Fadul Hospital in Sudan and Najran University Hospital in the Kingdom of Saudi Arabia during July 2015-July 2016. In antenatal clinic pregnant women were scanned in their third trimester by sonographic ultrasound. After completion of the one year data regarding the detailed obstetrical and surgical history were recorded in a questionnaire form. The data were analyzed using Statistical Social Package for Social SciencesVersion20SPSS. All analyses were performed using descriptive crosstabs and to determine and arrangement the risk factors by using model logistic regression. Total number of deliveries during the study period was 400. Of them 125 (31.25%) by pp. Of the latter 65 (16.25%) and 60 (15% ) were diagnosed as placenta previa in both study groups in Sudan and KSA respectively. The incidence of placenta previa was directly related to the previous cesarean sections71 (17.75 %), parity55 (13.75 %), previous placenta previa 32 (8%) by crosstabs. These risk factors represented by the following equations by using logistic regression. (Y)Log p/1-p =1.679+ 1.365* pervious cesarean section + 0.768* parity. (Y)Log p/1-p =1.354+1.752* pervious cesarean section+ 1.602*previous placenta previa+1.191*assisted conception.
