Suicide prevention through means restriction: Impact of the 2008-2011 pesticide restrictions on suicide in Sri Lanka.

ABSTRACT:

Objective

To investigate the effect of 3-year phased bans of the pesticides dimethoate and fenthion in 2008-2010, and paraquat in 2009-2011, on suicide mortality in Sri Lanka.

Methods

Age-standardised overall, sex-specific, and method-specific suicide rates were calculated using Sri Lankan police data (1989-2015). Using negative binomial regression models, we estimated the change in the rate and number of suicide deaths in post-ban years (2011-15) compared to those expected based on pre-ban trends (2001-10).

Findings

Overall suicide mortality dropped by 21% between 2011 and 2015, from 18.3 to 14.3 per 100,000. The decline in pesticide suicides during this same period was larger than for overall suicides: from 8.5 to 4.2 per 100,000, a 50% reduction. This was accompani
