Suicidal attempts and self-poisoning: 1-year retrospective cohort study from the quaternary hospital in Thai metropolitan area.

Majority of self-poisoned patients in Bangkok were young adults taking medications, which differs from the overall Thai population where most instances involve patients of older patients (30-50 years) and ingestion of agricultural substances. Appropriate strategies are needed for specific psychosocial/socioeconomic contexts and within the critical period after previous nonfatal attempts.
