Neighborhood social composition and refugee mental health - quasi-experimental evidence of associations from a Danish population register study.

BACKGROUND: Refugees are at an elevated risk of some mental disorders with studies highlighting the contributing role of post-migration factors. Studies of migrant groups show neighborhood social composition, such as ethnic density, to be important. This is the first longitudinal study to examine this question for refugees and uses a novel quasi-experimental design. METHODS: We followed a cohort of 44 033 refugees from being first assigned housing under the Danish dispersal policy, operating from 1986 to 1998, until 2019. This comprised, in effect, a natural experiment whereby the influence of assigned neighborhood could be determined independently of endogenous factors. We examined three aspects of neighborhood social composition: proportion of co-nationals, refugees, and first-generation migrants; and subsequent incidence of different mental disorders. RESULTS: Refugees assigned to neighborhoods with fewer co-nationals (lowest v. highest quartile) were more likely to receive a subsequent diagnosis of non-affective psychosis, incident rate ratio (IRR) 1.25 (95% confidence interval (CI) 1.06-1.48), and post-traumatic stress disorder (PTSD), IRR 1.21 (95% CI I.05-1.39). A comparable but smaller effect was observed for mood disorders but none observed for stress disorders overall. Neighborhood proportion of refugees was less clearly associated with subsequent mental disorders other than non-affective psychosis, IRR 1.24 (95% CI 1.03-1.50). We found no statistically significant associations with proportion of migrants. CONCLUSIONS: For refugees, living in a neighborhood with a lower proportion of co-nationals is related to subsequent increased risk of diagnosed mental disorders particularly non-affective psychosis and PTSD.

Duration of Mentoring Relationship Predicts Child Well-Being: Evidence from a Danish Community-Based Mentoring Program.

While a substantial body of literature suggests that lasting community mentoring relationships can have a range of positive effects on youths, little is known about these effects in the Nordic welfare context, where community mentees may have lower risk profiles compared to many previous samples. This study explores how the duration (length) of child mentoring relationships predicts parental perceptions of child well-being among 197 children served by Denmark's most extensive community-based youth mentoring program. We find that children who have had a mentor for at least one year are perceived to have significantly higher well-being. In contrast, we find no significant differences in well-being between children who had mentors for less than one year and children on a waiting list. Previous research, conducted in primarily North American contexts, finds that longer mentoring relationships substantially improve school behavior and reduce risk taking. Our results add to the literature by indicating that a minimum mentoring relationship duration of one year appears to be similarly important in promoting well-being for youths involved in community-based mentoring programs in a Nordic welfare context.
