The Jeopardy Index was used to quantify cumulative social disadvantage based on sex, race\/ethnicity, and maternal education. Suicidal ideation and planning were the primary outcomes, each categorized dichotomously, and analyzed using survey-weighted logistic regression models.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Suicidal behaviors increased significantly over the study period: ideation rose from 11.2% to 26.7%, and planning from 7.8% to 22.1%, with the most pronounced increase between 2016 and 2022. Among adolescent females, ideation reached 35.3% and planning 30.3%, compared to 16.2% and 12.1% among males. Each one-unit increase in the Jeopardy Index was associated with a 6% increase in the odds of suicidal ideation (OR\u2009=\u20091.06) and a 9% increase in the odds of suicidal planning (OR\u2009=\u20091.09).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Social disparities do not operate in isolation. The cumulative burden of vulnerabilities, particularly the intersection of sex, race\/ethnicity, and socioeconomic disadvantage, was associated with increased risk of suicidal ideation and planning.
