"Exposure to racism and discrimination and the perception of low social position are consequences of minority status that may lead to depression, anxiety and feeling like 'the other,'" she adds.

The Boricua Youth Study is the first large longitudinal study examining what puts minority youth at risk for depression and anxiety. The study was conducted by Alegria and colleagues at MGH, Harvard Medical School, Columbia University and the University of Puerto Rico.

Researchers looked at 1,863 Puerto Rican youth ages 15-29 living in New York's South Bronx and San Juan, Puerto Rico to explore whether growing up as part of a minority group in disadvantaged neighborhoods puts young people at risk for depression and anxiety and what factors lead to that risk. They also interviewed 1,100 parents and caregivers in both places to get their perspectives.

The researchers examined four general buckets of categories that influence mental health: environmental and social factors, cultural and minority stress, parent and peer relations, and family/individual vulnerability.

The key influencers that put teens at risk for mood disorders included perceived discrimination (i.e., neighborhood discrimination, the stress of being a minority and unfair treatment) and cultural factors (i.e., weaker ethnic identity and intercultural conflict). The strengths of childhood social support and good peer relationships explained the differences in mental health outcomes between minority/majority youth.

As a minority group, youth in the South Bronx also face complex home dynamics that could affect their mental health. Families often provide Latino youth with a sense of identity and source of connection to their culture. Researchers found that intergenerational conflicts sometimes stemmed from minority youth assimilating to New York's cultural norms.

Compared to their peers in Puerto Rico, parents in the South Bronx reported more neighborhood discrimination, a lower level of family connection, and more family cultural distress. Similarly, young people in the South Bronx reported the weaker ethnic identity and lower levels of familism than their peers in Puerto Rico.

The authors note that the findings have implications for immigrant youth nationally since "It is not an individual risk but rather the environments and social context that could play a prominent role in the development of internalizing disorders."

Neighborhood-based interventions focused on building positive social relationships, like youth civic organizations in after school programs could be effective ways to combat anxiety and depression among minority youth, the authors add. Strong parental and peer relationships also offer these youth important buffering tools to combat the stress of discrimination and counter the negative social mirror that puts them at risk for internalizing experiences.
