Background: Refugees are forced migrants but there is a large variation in the distance that refugees cover and there is a paucity in the evidence of how this may affect refugees' health and health care needs.
Objective: We investigated the association between long-distance migration and post-traumatic stress disorder (PTSD), a serious psychiatric disorder associated with deteriorating mental and somatic health.
Methods: Included from 2016-2019 were adult Syrian refugees in Lebanon and Denmark that arrived up to 12 months prior to inclusion.
