Ethnocultural differences in prevalence of adolescent depression

Area of Science:

• Psychiatry
• Public Health
• Sociology

Background:

• Major depression is a significant public health concern among adolescents.
• Ethnic disparities in mental health are increasingly recognized.
• Understanding prevalence across diverse groups is crucial for effective interventions.

Purpose of the Study:

• To examine ethnic differences in the prevalence of major depression among middle school students.
• To identify specific ethnic groups at higher risk for depression, with and without impairment.
• To inform targeted public health and community intervention strategies.

Main Methods:

• Analysis of data from a large, ethnically diverse sample of middle school students (n = 5,423).
• Calculation of point prevalence rates for major depression, both with and without impairment, across nine ethnic groups.
• Multivariate logistic regression analyses adjusting for age, gender, and socioeconomic status (SES).

Main Results:

• Overall point prevalence of major depression was 8.4% without impairment and 4.3% with impairment.
• Prevalence adjusted for impairment ranged from 1.9% (Chinese descent) to 6.6% (Mexican descent).
• Mexican American youths exhibited significantly elevated risk for depression, both with (OR = 1.71) and without impairment (OR = 1.74), after adjusting for covariates. Females and those with lower perceived SES also showed higher rates.

Conclusions:

• Mexican American youth are at a significantly increased risk for major depression.
• Findings underscore the need for culturally sensitive and targeted community interventions for this high-risk population.
• No significant interaction was found between ethnicity and SES in relation to depression.
