Exploring the Roles of Familial and Dating Relationship Violence and Sexual Assault on Adolescent Girls and Young Women's Risk of Partner Violence in Tanzania.

This study explored the role of non-partner violence on adolescent girls and young women's (AGYW) risk of partner violence in Tanzania. Among currently partnered AGYW, 36.7% reported lifetime physical and/or sexual partner violence. Prevalence of parental punishment, dating relationship violence, and sexual assault measured 3.0%, 2.5%, and 2.9%, respectively. There is evidence that exposure to all forms of non-partner abuse is associated with partner violence. Population attributable fractions suggest that 20% of partner violence incidence was because of non-partner violence. Adolescence and young adulthood is a critical intervention age group to prevent multiple forms of violence including in intimate relationships.
