Changing profile of suicide methods in India: 2014–2021.

Restricting access to suicide methods is one of the most effective suicide prevention approaches. Trends in method specific suicide rates (2014–2021) in India were calculated using National Crime Records Bureau data (NCRB) by sex and geographical region. Joinpoint regression analysis was used to empirically identify any changes in suicide trends. Suicide rates by hanging increased from 6.08 to 10.0 per 100,000 population among males and from 2.55 to 3.56 per 100,000 among females over the study period. Insecticide poisoning suicide rates also increased from 1.51 to 2.73 per 100,000 among males and from 0.74 to 1.14 per 100,000 among females. Suicide by self-immolation decreased over the study period among both sexes. In general, these national trends were mirrored among different regions. Joinpoint regression indicated an increase in suicide by hanging (annual percentage change (APC) of 12.3 among males between 2018 and 2021 and 4.9 among females between 2014 and 2021) and an increase in male suicide by insecticide poisoning between 2014 and 2021 (APC of 4.2) while a decrease in self-immolation rates was noted among males (APC of −12.7 between 2014 and 2021) and females (APC of −16.5 between 2016 and 2021). The NCRB data might underestimate true suicide rates. Hanging suicides and insecticides poisoning suicides observed an increasing trend between 2014 and 2021. Self-immolation rates decreased during the study period which might be, in part, associated with the initiative to provide clean cooking fuel to households. Ban on lethal pesticides must be prioritised which might help lower insecticide poisoning suicide rates. • Hanging had the highest method specific suicide rate among both sexes showing a consistent rise over the study period • Suicide by insecticide poisoning also showed an increasing trend over the study period, especially among males • Suicide by self-immolation decreased over the study period among both sexes • Government's initiative to provide clean cooking fuel to rural households might have helped reduce self-immolation rates • It is imperative that lethal pesticides are banned in India which might help reduce insecticide poisoning suicides [ABSTRACT FROM AUTHOR]
