Family networks during migration and risk of non-affective psychosis: A population-based cohort study.

ABSTRACT:

Objective

The determinants of increased psychosis risk among immigrants remain unclear. Given ethnic density may be protective, we investigated whether the presence of immediate family, or "family networks", at time of immigration was associated with risk of non-affective psychosis.

Methods

We followed a cohort of migrants (n = 838,717) to Sweden, born 1968-1997, from their 14^th birthday, or earliest immigration thereafter, until diagnosis of non-affective psychosis (ICD-9/ICD-10), emigration, death, or 2011. Using record linkage, we measured family network as the presence of adult first-degree relatives immigrating with the cohort participant or already residing in Sweden. We used Cox proportional hazards regression to examine whether risk varied between those mi
