The association between intimate partner violence, depression and influenza-like illness experienced by pregnant women in Australia

Abstract

Intimate Partner Violence (IPV) is a major public health issue, including during pregnancy where it poses a serious risk to the woman’s health. Influenza-Like Illness (ILI) also causes significant morbidity for women during pregnancy. It may be possible that ILI in pregnancy is associated with IPV, and that depression and trauma history play a role in the connection. 524 Australia-born women and 578 refugee-background women participated in the study. Baseline participants were randomly recruited and interviewed from antenatal clinics between January 2015 and March 2016, and they were reinterviewed six months post-partum. Bivariate and path analysis were used to assess links between IPV, depression and ILI. One in 10 women (10%; 111 out of 1102) reported ILI during their pregnancy period and this rate was significantly (p < 0.001) higher for women born in conflict-affected countries (13%; 76 out of 578) as compared to Australian-born women (7%; 35 out of 524). In both groups, Time 1 traumatic events, IPV and depression symptoms were significantly associated with ILI at Time 2. A significant association between IPV at Time 1 and ILI at Time 2 was fully mediated by depression symptoms at Time 1 (Beta = 0.36 p < 0.001). A significant direct path was shown from depression symptoms to ILI (Beta = 0.26, p < 0.001). Regardless of migration history, pregnant women who have experienced IPV and depression are more likely to report influenza-like symptoms in pregnancy. This may suggest that trauma and depression negatively affect immunity, although it could also indicate a connection between depressive symptoms and physical experiences of ILI.<br/ ><br/ >Keywords: intimate partner violence; influenza-like illness; depression; trauma; pregnancy
