Armed conflict, displacement, and related violence is escalating globally, concentrated among civilians and migrants in border areas, and poses grave harms to women and children. The current study investigates how women’s life-course experiences of conflict and displacement are linked to maternal stress and health outcomes after childbirth at the Thailand-Myanmar border, specifically stress, mental health, and cardiometabolic outcomes. Analyses are based on a cross-sectional population-based maternal and child health survey of 701 mothers, collected in 2017–18 in northern Thailand along the Myanmar border, including in camps, worksites, and residential homes. Results suggest that how conflict violence shapes contemporary stress and health depends on the outcome, level and timing of conflict violence exposure, and subsequent contextual threats and deprivation in displacement contexts. Past conflict violence was associated with symptoms of perceived stress (PS) and generalized anxiety disorder (GAD) but not depression. It was also associated with hypothalamic-pituitary-adrenal (HPA) axis activity (hair cortisol concentration) and adiposity (waist circumference and waist-to-hip ratio). Additionally, past conflict violence that began in childhood was particularly salient for PS, GAD, and adiposity; and level and timing of violence were salient jointly for HPA activity. Post-displacement factors also independently predicted higher blood pressure and played a potentially partial mediating role in the association between conflict exposure and both PS and GAD symptoms. •Echoes of conflict violence appeared in maternal stress and health in displacement settings.•Past conflict violence was associated with perceived stress, anxiety, cortisol, and adiposity.•Past conflict violence that began in childhood were particularly salient for stress, anxiety, cortisol, and adiposity.•Both level and timing of violence were salient for HPA activity, specifically cortisol regulation.•Post-displacement factors predicted higher blood pressure and may mediate impacts of conflict on stress and anxiety.
