Purpose: Evidence from systematic reviews suggests that adult immigrants living in areas of higher immigrant density (areas with a higher proportion of foreign-born residents) tend to experience fewer mental health problems-likely through less discrimination, greater access to culturally/linguistically appropriate services, and greater social support. Less is known about how such contexts are associated with mental health during childhood-a key period in the onset and development of many mental health challenges. This study examined associations between neighbourhood immigrant density and youth mental health conditions in British Columbia (BC; Canada)., Methods: Census-derived neighbourhood characteristics were linked to medical records for youth present in ten of BC's largest school districts from age 5 through 19 over the study period (1995-2016; n = 138,090). Occurrence of physician assessed diagnoses of mood and/or anxiety disorders, attention deficit hyperactivity disorder (ADHD), and conduct disorder was inferred through International Classification of Diseases (ICD) diagnostic codes in universal public health insurance records. Multi-level logistic regression was used to model associations between neighbourhood characteristics and odds of diagnoses for each condition; models were stratified by generation status (first-generation: foreign-born; second-generation: Canadian-born to a foreign-born parent; non-immigrant)., Results: Higher neighbourhood immigrant density was associated with lower odds of disorders among first-generation immigrant youth (e.g., adjusted odds of mood-anxiety disorders for those in neighbourhoods with the highest immigrant density were 0.67 times lower (95% CI: 0.49, 0.92) than those in neighbourhoods with the lowest immigrant density). Such protective associations generally extended to second-generation and non-immigrant youth, but were-for some disorders-stronger for first-generation than second-generation or non-immigrant youth., Conclusions: Findings suggest there may be protective mechanisms associated with higher neighbourhood immigrant density for mental health conditions in immigrant and non-immigrant youth. It is important that future work examines potential pathways by which contextual factors impact immigrant and non-immigrant youth mental health., (© 2022.

Using a linked population-based database established on healthcare, socio-economic, and survey datasets in British Columbia, Canada, we examined how biological, socio-demographic, and socio-economic status (SES) factors at birth related to children's emotional development and mental health. One analysis examined teacher-rated anxiety, hyperactivity, and aggression for kindergarten children (Mage = 5.7; n = 134,094). Another analysis examined administrative healthcare records comprising of physician-assigned diagnostic codes for mental health conditions (conduct disorder, attention deficit hyperactivity disorder, anxiety disorder and depression) from ages 5 through 15 (n = 89,404). Various factors at birth, including gestational age, birthweight, and maternal demographics, were related to emotional development and mental health in childhood. Across outcomes, low SES indicated detrimental associations with various aspects of children's emotional development and mental health (e.g., adjusted odds of mental health conditions were 25-39% higher for children of low income families versus others). Findings reinforce evidence that poverty (reduction) is a primary public health issue. [ABSTRACT FROM AUTHOR]

Background: There is evidence that siblings of children with a developmental disability (DD) experience poorer mental health outcomes and increased stress compared to siblings of non-disabled children. The variables which contribute to this are unclear.Aims: This study was designed to examine population-level and individual variables associated with differences in mental health outcomes among siblings of children who have a variety of developmental disabilities.Methods: Population-level administrative health data covering 1985-2014 for the province of British Columbia, Canada were used to develop a cohort of over 45,000 children who have a sibling with a DD. Individual-level, demographic and health care services variables were used in logistic regression to assess their relationship to diagnoses of depression or other mental health problems.Outcomes: Odds of a diagnosis of depression or a mental health problem other than depression were associated with sex of the non-disabled sibling, sex of the child with the developmental disability, type of disability, birth order and income.Conclusions: Type of developmental disability, and characteristics of the non-disabled sibling and their family are associated with mental health outcomes of siblings of children with a DD.
