MAPI Study: Violence and Adolescent Health in Mexico

Violence is a global health crisis that disproportionately affects poor Latin American populations, yet there is scarce research conducted in Mexico. Given the pivotal developmental stage of adolescence, it is crucial to understand the effects of violence exposure and identify protective factors that buffer its impact.

This study investigates how multiple forms of community violence (e.g., neighborhood violence, sexual harassment) affect the psychological (anxiety, depression, PTSD) and immune (inflammation levels) health of Mexican adolescents. Surveys and serum blood samples were collected from 349 students in Uruapan, Michoacán, including pro-inflammatory cytokine markers from 250 participants.

Drawing from a strengths-based resilience framework, the study also examines protective factors such as close parent-adolescent relationships, familismo, and school belonging.

This is the first study in Mexico to combine surveys and biomarkers to examine the relationship between violence and adolescent health. Findings aim to inform culturally responsive interventions for Latino youth inside and outside the U.S.
