Neighborhood-level Social Determinants of Health and Adolescent Mental Health.

Abstract

Objective: Mental health diagnoses among adolescents are increasing in prevalence. Existing literature considers associations between individual-level social determinants of health (SDOH) and adolescent mental health. Yet, neighborhood-level SDOH can have a substantial impact on health. This paper examines associations between neighborhood-level SDOH and mental health diagnoses of anxiety, depression, and suicidal ideation among hospitalized adolescents.

Methods: We used 2018 and 2019 Texas Inpatient Discharge Public Use Data Files linked to the zip-code level Child Opportunity Index 2.0, a composite measure of subdomains which characterize neighborhood-level SDOH, to examine rates of mental health diagnoses and associations with patient characteristics across opportunity level quintiles.

Results: The sample included 50,011 adolescents ages 10-19 admitted to the hospital with the mental health diagnoses anxiety, depression, and/or suicide. Most had a single diagnosis; anxiety (12.9%), depression (37.5%), or suicide (13.0%). Hospitalized adolescents 10 to 14 years old were a plurality (44.2%) of the sample. Most adolescents were White (64.2%) and non-Hispanic (67.4%) and lived in rural areas (29.6%). Adolescents from racial minority populations and those in rural communities with mental health diagnoses had lower opportunity-levels. Higher opportunity levels were associated with greater odds of having an anxiety or suicide diagnosis while a depression diagnosis was associated with a lower opportunity-level.

Conclusions: There are significant differences in adolescent mental health diagnoses associated with neighborhood opportunity-level. While all adolescents can benefit from mental health education, screening, and early interventions, additional resources tailored to neighborhood-level opportunity may prove a more meaningful way to improve population-level mental health outcomes.
