Perspective Challenges and opportunities in suicide prevention in South-East Asia Lakshmi Vijayakumar Sneha – Suicide Prevention Centre and Voluntary Health Services, Chennai, Tamil Nadu, India Correspondence to: Dr Lakshmi Vijayakumar ([email protected]) Abstract Suicide is a global public health problem, with over 800 000 people worldwide dying by suicide in 2012, according to the World Health Organization (WHO). The WHO South-East Asia Region is especially affected, with 39% of global suicides occurring in the 11 countries in this region. Women are a particularly vulnerable population, for a variety of social and cultural reasons. In India specifically, deaths by suicide for women peak in the age range 15–29 years. There is sufficient evidence to show that reduction of easy access to means of suicide is an effective prevention strategy. A common method of suicide in the region is by ingestion of pesticides. Strategies that have targeted limiting access to pesticides as a means of preventing suicide, such as the use of central storage and locked boxes, have shown promising results. Given the limited human and economic resources in these countries, it is essential to involve all stakeholders, including health services, voluntary and community organizations, teachers, social workers, traditional healers and other gatekeepers, in suicide prevention. A multisectoral approach, specifically targeting women and reducing easy access to pesticides, should be the way forward to reducing suicides in this region. In addition, more research is needed, to identify cost-effective and sustainable strategies.

Countries from the WHO South-East Asia Region, with an Women as a vulnerable group estimated 314 000 suicides in 2012, accounted for 39% of all global suicides.1 This region consists of 11 low- and middle- Women in low- and middle-income countries are especially income countries, which constitute 26% of the global population.1 vulnerable to suicide; the male-to-female ratio for completed India accounted for 258 000 (82%) of the suicides in the suicides is much narrower in these countries, at 1.6, compared to countries of the South-East Asia Region in 2012, and so the the value of 3.5 in high-income countries.1 An estimated 124 282 characteristics of suicide in India shape the pattern seen women died by suicide in the countries of the WHO South-East across the region. The 2012 suicide rate in the region was 17.7 Asia Region in 2012, meaning that a little less than half of global per 100 000 population, the male-to-female sex ratio was 1.6, suicides in women occurred in this region. Compared to women and suicide accounted for 1.8% of all deaths, making it the from low- and middle-income countries of all other WHO regions, 11th-most important cause of death in the region.1 In India, the women in countries of South-East Asia have higher suicide rates. age-by-sex pattern of suicide showed different rates by age. The suicide rate (per 100 000) for women from the South-East Among males, the rates rose rapidly after the age of 15 years, Asia Region was 11.9, while the next highest was 5.6 from the low- remained stable from 30 to 70 years, and then increased and middle-income countries of the European Region. This higher gradually, while in females there was a large peak of 36.1 rate was also maintained across all age ranges (see Table 1).1 per 100 000 deaths by suicide in the age range 15–29 years, In several countries of the region, notably Bangladesh, India lower rates in the age range 30–49 years, and then gradually and Indonesia, the male-to-female ratio for suicide among increasing rates after 50 years.1 younger people (below 30 years of age) showed that the rates From 2000 to 2012, the absolute number of suicides in were higher for women.
