Over the last two decades, the international community has expressed concerns on the increasing occurrence of gender-based violence and related consequences, particularly in African and many low-and middle-income countries. The 2006 United Nations General Assembly declaration on elimination of violence against women has been applauded across many settings. Intimate partner violence is a typical example of gender-based violence that occurs among males and females who have intimate relationships either as husbands and wives, or are in cohabiting relationship. This paper examines factors likely to influence gender-based violence and effects on pregnancy outcomes in Nigeria. The study used the 2013 Nigeria Demographic and Health Survey (NDHS) couple data set of 8658 couples aged 15-49 for women and 15-59 for men. 6,961 were interviewed for domestic violence. Analysis employed univariate, bivariate and multivariate techniques i.e. binary logistic regression. Pregnancy outcome, measured as either live birth or stillbirth is the ultimate dependent variable. Explanatory factors are of two types (1) intervening factors are, physical, and emotional violence, and (2) background factors including age, residence, education, employment status, and religion among others. The results showed that residence, employment status, religion and partner’s age were significant factors explaining emotional, and physical violence among couples (p<0.05) While physical violence and emotional violence were significant associated with pregnancy outcome of either a live birth or still birth (P<0.05). The study also showed that respondents whose husband takes alcohol have a higher odds of experiencing violence while those who are working and educated beyond primary school also have higher odds of experiencing violence. These findings have significant implications for policy and programmes geared to improve on gender equity, and reproductive health of women in Nigeria.
