Factors associated with single and multiple suicide attempts in adolescents attending school in Argentina: national cross-sectional survey in 2018.

Psychosocial distress (anxiety-induced sleep disturbance, having no close friends and loneliness) increased the odds of MSA among both sexes. The odds of MSA were increased by interpersonal violence, low parental support and substance use among girls, and by having multiple sexual partners among boys. This suggests the potential relevance of these variables in identifying multiple suicide attempters among adolescents attending school in Argentina.
