Forced residential mobility and social support: impacts on psychiatric disorders among Somali migrants

An in-depth and semi-structured interview was used to gather detailed accommodation histories for a five year period from 142 Somali migrants recruited in community venues and primary care. Post-codes were verified and geo-mapped to calculate characteristics of residential location including deprivation indices, the number of moves and the distances between residential moves. We asked about the reasons for changing accommodation, perceived discrimination, asylum status, traumatic experiences, social support, employment and demographic factors. These factors were assessed alongside characteristics of residential mobility as correlates of ICD-10 psychiatric disorders.Those who were forced to move homes were more likely to have an ICD-10 psychiatric disorder (OR = 2.64, 1.16-5.98, p = 0.02) compared with those moving through their own choice. A lower risk of psychiatric disorders was found for people with larger friendship networks (0.35, 0.14-0.84, p = 0.02), for those with more confiding emotional support (0.42, 0.18-1.0, p = 0.05), and for those who had not moved during the study period (OR = 0.21, 0.07-0.62, p = 0.01).Forced residential mobility is a risk factor for psychiatric disorder; social support may contribute to resilience against psychiatric disorders associated with residential mobility.Migration can be conceptualized as arising due to 'push' factors like civil war, persecution, and discrimination; these are also determinants of psychiatric disorders [1]. Migration can also occur due to 'pull' factors like seeking employment, and to live with friends and family. Asylum seekers and refugees are at greater risk of psychiatric disorders because of the risks associated with migration itself [1], and due to severe traumatic life events, usually in the context of conflict and persecution, before and during asylum journeys [2]. Contrasting with the hazards before migration and during asylum-seeking journeys, some research is beginning to show that adversities in
