Study: Suicide Prevention in Less Well-Off Countries Needs Wider Approach

A new study suggests that the treatment and prevention of suicidal behavior in low- and middle-income countries (LMIC) should involve a wider range of approaches beyond just the treatment of psychiatric illness.

There are 800,000 suicide deaths annually, and the vast majority (76 percent) are from LMIC. However, current evidence into suicide prevention is largely based on high-income countries (HIC) and suggests more than 80 percent of suicidal behavior is linked to psychiatric disorders. Prevention initiatives in LMIC have been relatively neglected to date.

The study, published in the journal PLOS Medicine, is the first systematic review of the link between psychiatric disorders, such as depression, anxiety and schizophrenia, and suicidal behavior in LMIC.

“This is the first time we’ve really been able to take an overall look at what we already know about the association between psychiatric morbidity and suicidal behaviour in LMIC,” said Dr. Duleeka Knipe, Elizabeth Blackwell Institute (EBI) Vice Chancellor’s Research Fellow at the University of Bristol Medical School.

“Our analyses show there is a lot of variability between studies and countries, and this suggests there is no one answer, but does support our thinking that psychiatric disorder is perhaps not as important in these settings as in higher income countries.”

“Of course, the treatment of underlying psychiatric illness is important but prevention efforts should also incorporate a wider range of activities which aim to reduce access to lethal means, poverty, domestic violence and alcohol misuse. For example, population level solutions, such as banning highly toxic pesticides, have been shown to be effective in reducing the number of suicide deaths.”

An international research team, comprising experts from the universities of Manchester, Birmingham, Sheffield Hallam, Nottingham, Western Sydney and National Taiwan University, looked at data from 112 studies on 30,030 episodes of non-fatal suicidal behavior and 4,996 suicide deaths in 26 LMIC.

The study, which aimed to address the issue of suicide prevention in LMIC, found 58 percent of suicide deaths and 45 percent of non-fatal suicidal behaviors were linked to psychiatric disorders.

The researchers also found that the proportion of psychiatric disorders in suicidal behavior was highly variable, possibly reflecting between-country differences.

In HIC the treatment of psychiatric disorder is a key focus for suicide prevention, but this study suggests that a wider approach might be needed in LMIC.

“Despite the huge toll of deaths, suicide prevention in LMIC has been relatively neglected to date,” said Dr. Nav Kapur, professor of psychiatry and population health at the University of Manchester and the senior author on the paper. “Of course, we need more research — that much is clear. But we also need to get on and implement solutions based on what we already know.”
