Abstract summary 

Hundreds of thousands of Rwandans were conceived during the 1994 genocide against the Tutsi, including thousands conceived by genocidal rape. We explore whether the duration of first trimester exposure to the genocide is associated with variation in adult mental health outcomes in individuals exposed to varying degrees of genocide-related stress in utero.We recruited 30 Rwandans conceived via genocidal rape, 31 Rwandans conceived by genocide survivors not raped, and 30 individuals of Rwandan-descent who were conceived outside of Rwanda at the time of the genocide (control group). Individuals were age- and sex-matched across groups. Adult mental health was assessed through standardized questionnaires for vitality, anxiety, and depression.Among the genocide only group, a longer duration of first trimester prenatal exposure was associated with higher anxiety scores and lower vitality (both p < 0.010), and higher depression scores (p = 0.051). Duration of first trimester exposure was not associated with any measures of mental health among the genocidal rape or control group.Duration of exposure to genocide in the first trimester of gestation was associated with variation in adult mental health among the genocide only group. The lack of association between duration of first trimester exposure to genocide and adult mental health in the genocidal rape group may reflect the fact that stress associated with conception through rape persisted beyond the genocide period itself, encompassing all of gestation and likely beyond. Geopolitical and community interventions are needed in the context of extreme events during pregnancy to mitigate adverse intergenerational outcomes.
