Prevention is the umbrella in working toward reducing deaths by suicide; increasing awareness, eliminating stigma, knowing what to do in the event that you or someone you know experiences thoughts or behaviours associated with suicide. It’s having the skills, awareness, before someone is in crisis. In preventing suicide, intervention and postvention are components toward the goal of reducing suicides.
Who is at Risk of Dying by Suicide?
Older adults are at higher risk due to life changes and transitions through loss, lifestyle changes due to physical disability, a move from independent living to assisted living and social isolation and abuse. Warning signs: appetite changes, lack of participation in social events, signs of abuse and neglect.
Young people are at higher risk due to family and school pressures, major life changes, hormone changes, bullying and sexual orientation issues.
Warning signs: eating disorders, deliberate self-harm, withdrawal from normal activities, exceptional and extreme mood swings, perfectionist behaviour or extreme self-critical behaviour
People who have recently had a major loss or life change are at higher risk, as grief can change to depression that may last several weeks or longer.
Warning signs: major changes in attitude, changes in eating or sleeping habits, loss of energy or loss of interest in things that were once enjoyed.
Especially vulnerable are people who are recovering from an episode of depression or who have a history of suicide attempts, or who have just been released from the hospital.
