Abstract

As the largest continent in the World, Asia accounts for about 60% of World suicides. Preventing suicide by restricting access to suicide methods is one of the few evidence-based suicide prevention strategies. However, there has been a lack of systematic exploration of suicide methods in Asian countries. To amend this shortage, the current review examines the leading suicide methods in different Asian countries, their trend, their age- and sex- specific characteristics, and their implications for suicide prevention. In total, 42 articles with leading suicide methods data in 17 Asian countries/regions were retrieved. The epidemiologic characteristics and recent trends of common suicide methods reflect specific socio-cultural, economic, and religious situations in the region. Common suicide methods shift with the introduction of technologies and constructions, and have specific age- or sex-characteristics that may render the restriction of suicide methods not equally effective for all sex and age sub-groups. Charcoal burning, pesticide poisoning, native plant poisoning, self-immolation, and jumping are all prominent examples. In the information society, suicide prevention that focuses on suicide methods must monitor and control the innovation and spread of knowledge and practices of suicide “technologies”. It may be more cost-effective to design safety into technologies as a way of suicide prevention while there is no rash of suicides yet by the new technologies. Further research on suicide methods is important for public health approaches to suicide prevention with sensitivity to socio-cultural, economic, and religious factors in different countries.

  • Intentional self-poisoning is one of the most frequently used methods of committing suicide, along with using firearms and committing suicide by hanging.

    “Intentional self-poisoning is one of the most frequently used methods of committing suicide, along with using firearms and committing suicide by hanging [12].”

    From Toxicological Findings of Self-Poisoning Suicidal Deaths: A Systematic Review by Countries (2022) · cites this paper as [12]

    The Results (§3.1) and Discussion (§4.1) identify hanging and solid/liquid self-poisoning as dominant suicide methods in Asia. The Results also list firearms among common methods in a European study, but say firearms are not a leading method in most Asian countries studied. The source therefore does not support presenting all three as generally among the most frequently used methods without a geographic qualifier. (LLM, conf=0.84)

  • In many low-income countries in the Asia-Pacific region, suicide is the leading cause of death in early to middle adult life and pesticides account for around half to two-thirds of the suicides.

    “In many low-income countries in the Asia-Pacific region, suicide is the leading cause of death in early to middle adult life and pesticides account for around half to two-thirds of the suicides.”

    From Toxicological Findings of Self-Poisoning Suicidal Deaths: A Systematic Review by Countries (2022) · cites this paper as [12]

    The Introduction says suicide is one of the leading causes of death worldwide, and Results §3.1 identifies pesticide-related poisoning as the leading suicide method in China, Pakistan, and Sri Lanka. The paper does not establish that suicide is the leading cause of death in early to middle adulthood across many low-income Asia-Pacific countries, or that pesticides account for half to two-thirds of suicides there. The passages in our copy have no page numbers. (LLM, conf=0.85)

    Experimental — accuracy not yet measured
  • Depression was the most relevant risk factor associated with suicide.

    “Depression was the most relevant risk factor associated with suicide.”

    From Toxicological Findings of Self-Poisoning Suicidal Deaths: A Systematic Review by Countries (2022) · cites this paper as [12]

    The Discussion (§4.2; page unavailable) addresses the availability and cultural acceptability of suicide methods, not depression as a risk factor. Searches for “depression,” “mental disorders,” and suicide risk found no passage in our copy identifying depression as the most relevant risk factor; the depression hit is only in a reference title. (LLM, conf=0.76)

    Experimental — accuracy not yet measured
  • There is a robust association between suicide and depression.

    “The robust association between suicide and depression demands that greater attention be paid to diagnosing this mental disorder, particularly in primary healthcare, and the interventions designed to treat depression are considered as essential to preventing suicide [12,58].”

    From Toxicological Findings of Self-Poisoning Suicidal Deaths: A Systematic Review by Countries (2022) · cites this paper as [12]

    The Conclusions (section 5) discuss suicide methods and restricting access to means, not an association between suicide and depression. Searches for “depression” and related mental-health terms found only reference-list entries, not a passage stating the claimed association. (LLM, conf=0.76)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
