Sinn Féin MLA and Junior Minister Jennifer McCann said people from deprived communities are three times more likely to die by suicide than those better off.
And she said that targeted programmes and interventions aimed at those who are most disadvantaged and in most need are central to tackling the problem.
Speaking following a Ministerial Co-ordination Group on suicide prevention, the West Belfast MLA said:
"A person from a deprived community is three times more likely to die through suicide, than those living in a less deprived area.
"We need to do more to tackle the underlying causes, which lead people to suicide.
"Evidence shows that unemployment, poverty and poor educational and health outcomes effect people’s mental health and emotional well being.
"They can lead to problems including alcohol and drug dependency, lack of confidence and low self esteem, which can make people feel isolated and vulnerable.
"Targeted programmes and interventions aimed at those who are most disadvantaged and in most need are crucial.
"Challenging inequalities, tackling deprivation and promoting positive mental health and emotional well being are key factors in suicide prevention.”
