Depression and suicidal ideation among undergraduates in state tertiary institutions in Lagos Nigeria.

The proportion of respondents with good knowledge of depression was not satisfactory. A strong relationship was found between depression and suicidal ideation indicating that people with depression are at a high risk of having suicidal ideation. Risk factors that were associated with depression and suicidal ideation were bullying, low self-esteem, intake of recreational drugs, alcohol dependence, poor academic performance, sexual assault and being hit by a partner. More works need to be done by the government and non-governmental organisations, school administration and parents to increase the awareness on the symptoms and manifestations of depression and reduce the burden created by some of the risk factors identified in this study to combat depression and suicidal ideation.
