BackgroundSuicide mortality is rising across many regions, such as Latin America, yet evidence on repeat suicidal behavior-the strongest predictor of eventual death by suicide-remains scarce.Chile is one of the few Latin-American countries with a national, event-level suicide-attempt surveillance system, offering a unique opportunity to study high-risk populations that are typically invisible in routine mortality statistics.Arica-Parinacota, Chile's northernmost border region, combines some of the highest adolescent suicide rates in the country with a substantial presence of indigenous and migrant populations.These groups, historically exposed to socioeconomic disadvantages and barriers to mental health care access, may face unique vulnerabilities in this border context, which could shape patterns of suicide reattempt differently
Jiménez et al. (Mon,) studied this question.
