Background: Intimate partner violence (IPV) affects millions of women each year and has been recognized as a leading cause of poor health, disability, and death among women of reproductive age. However, the existing studies about the association between IPV and contraceptive use have been found to be conflicting and relatively less studied, particularly in low and middle income countries, including Eastern Sub Saharan Africa (SSA). This study examines the relationship between IPV and contraceptive use in Eastern SSA countries. Methods: The Demographic and Health Surveys (DHS) from 2014 to 2017 were a multi-stage cluster sample survey of 30,715 ever married (or cohabitating) women of reproductive age from six countries. The six Eastern SSA datasets were pooled and multivariable logistic regression using a hierarchical approach was performed to examine the association between IPV and contraceptive use after adjusting for women, partners, and household and health facility factors. Result: Two thirds of women 67% [66.55, 67.88] were not using any modern contraceptive methods and almost half (48%) of the women had experienced at least one form of IPV from their partners. Our analysis showed a strong association with decreased odds of physical violence [adjusted odds ratios (aOR) = 0.72, 95%CI: 0.67, 0 0.78] among women not using any contraceptive methods. Other factors associated with women not using any contraceptive methods were older women (35–49 years), illiterate couples and women from poorest households. Women who had no access to any form of communication [aOR = 1.12, 95%CI: 1.08, 1.36], unemployed partner [aOR = 1.55, 95%CI: 1.23, 1.95] and women who travelled long distances to access health services [aOR = 1.16, 95%CI: 1.06, 1.26] significantly reported increased odds of not using any contraceptive methods. Conclusion: Our study indicated that physical violence was negatively associated with not using any contraceptive method among married women in Eastern SSA countries. Tailored intervention messages to reduce IPV including physical violence among women not using contraceptive methods in East Africa should target those from low-socioeconomic groups especially, older women with no access to any form of communication, unemployed partners, and illiterate couples.

Intimate partner violence (IPV) adversely affects female reproductive health in various ways. Similarly, it plays a critical role in women's unintended pregnancy. This study examines the relationship between IPV and unintended pregnancy in Eastern Sub-Saharan Africa (SSA) countries. This study uses data from the nationally representative Demographic and Health Surveys (DHS) in six Eastern African SSA countries. The original sample size was restricted to ever married (or cohabitating) women of reproductive age who completed the survey's Domestic Violence Module and had a pregnancy in the previous 5 years. Svyset proportion was used to estimate the prevalence and 95% confidence intervals (CI) of the study outcomes and multiple logistic regression was used to compare outcomes of last pregnancy by exposure to lifetime IPV committed by the most recent partner. The prevalence of unintended pregnancy in Eastern SSA was 38% [36.4, 40.34] among married women with high disparity among countries. This prevalence was 45% [42.05, 48.15] and 55% [50.0, 59.87] among women who had experienced any form of IPV and sexual violence, respectively. After adjusting for potential confounding factors, women with a history of sexual violence had a higher risk of unintended pregnancy [AOR: 1.80, 95% CI: 1.39, 2.33] and increased odds of unintended pregnancy for women who had more than five living children [AOR: 4.93, 95% CI: 3.40, 7.15], women who lived in rural residences [AOR: 1.42, 95% CI: 1.07, 1.90], and women who reported they had financial barriers for health care [AOR: 1.36, 95% CI: 1.13, 1.64]. Our findings suggest that IPV, particularly sexual violence, is a key player for higher risk of unintended pregnancy in Eastern SSA countries. This study highlights the need for developing programs and implementation of policies that integrate sexual reproductive health and IPV to reduce unintended pregnancy among married and single women.
