Association between child marriage and intimate partner violence. A comparative analysis of Uganda Demographic Health Surveys 2011 and 2016

The incidence of child marriage (CM) and intimate partner violence (IPV) are high in Uganda. The study sought to assess the association between child marriage and IPV across two waves of the Ugandan Demographic and Health Survey (UDHS). The evidence is important to inform policy implementation strategies aimed at curbing child marriages and IPV. We analyzed data from UDHS 2011 and 2016. The analysis was restricted to women who have ever cohabited. Simple and multiple logistic regression models were used to assess the association between child marriage and IPV. Following the 2011 and 2016 UDHS findings, child marriage was 54.7% in 2011 and 47.4% in 2016. Child marriage among the current adolescents increased from 9.4% in 2011 to 14.2% in 2016. According to UDHS 2011, 40.0% and 39.0% experienced physical and sexual violence respectively. In 2011 and 2016, 23.1% and 17.4% experienced both physical and sexual violence. There are higher odds of physical violence among child marriages compared to adult marriages in 2011 and 2016 (AOR = 1.44; 95% CI: 1.12-1.84 in 2011 and AOR = 1.26; 95% CI: 1.12-1.42). A wealthy or educated woman has lower odds (AOR = 0.61; 95% CI: 0.41-0.91 and AOR = 0.41; 95% CI: 0.25-0.66) to experience both physical violence and sexual violence than a poor or uneducated one. Alcohol is the most common cause of IPV. A woman married to an husband who consumes alcohol has higher odds of experiencing physical, sexual or both physical and sexual violence as compared to someone whose husband did not consume alcohol (AOR = 2.23; 95% CI:1.61-3.09 in 2011 and AOR = 2.42; 95% CI: 2.15-2.73 in 2016) Intimate Partner Violence is associated with child marriage, level of education, wealth quintile, residence, and partners alcohol consumption. Much emphasis needs to be directed to cultural, as well as social economic factors but more specifically on the contribution of women emancipation/empowerment to prevent IPV.
