Background: intimate partner violence-affected 30% of women in their lifetime globally. InrnEthiopia, according to the Ethiopia Demographic and Health Survey 2016 report, the prevalencernof intimate partner violence among ever-married women was 34% that varies across regionsrn(between 9% in Somali and 38% in Oromiya regions). Several studies showed that women whornexperienced intimate partner violence had a high risk of spontaneous abortion than women whorndidn’t experience intimate partner violence. rnObjectives: To measure the association of intimate partner violence during pregnancy andrnspontaneous abortion among those who attended maternal health service in Adigrat generalrnhospital, from July 2019 to June 2020, Tigray region, Ethiopia. rnMethods: Explanatory sequential mixed-method study design was used. Systematic probabilityrnsampling and convenience nonprobability sampling was used to select study participants for thernquantitative and qualitative approach. Bivariate and multivariate logistic analyses werernperformed to identify the association between intimate partner violence and spontaneousrnabortion. Muticollinary test was performed to test collinearity between independent variables.rnFor the qualitative approach data were analyzed using thematic analysis. rnResult: women who were exposed to intimate partner violence during pregnancy had 4 timesrnhigher odds of spontaneous abortion than mother who don’t expose to any form of intimaternpartner violence (AOR 4.65, 95% CI 1.94-11.14). Women who were exposed to physicalrnintimate partner violence during pregnancy had 3 times higher odds of spontaneous abortionrncompared to those who didn’t expose to physical intimate partner violence (AOR 3.06, 95% CIrn1.09-8.59). However emotional and sexual intimate partner violence doesn’t have a significantrnassociation with spontaneous abortion. From the qualitative approach study participants believedrnthat physical beating and stress had a relationship with spontaneous abortion. rnConclusion: This study shows that spontaneous abortion is significant associated with exposurernto any form of intimate partner violence and physical intimate partner violence duringrnpregnancy. We could prevent spontaneous abortion-related to intimate partner violence byrnHealth care providers’ identifying and counsel mothers about intimate partner violence whenrnassessing spontaneous abortion patients.
