In this study indicators associated with suicidal ideation and suicide attempts in a nationwide representative sample (N = 3,184) of Danes aged 16-35 years were examined. The study was cross-sectional and had three aims: (1) to draw a profile of persons with and without suicidal tendency established on a combined quartered variable on current suicidal thoughts and/or ever attempted suicide; (2) to explore whether the different suicidal tendencies constitute a severity continuum; and (3) to identify factors of significance for suicidal tendency. Factors included were demographic characteristics, living conditions, social network, external health risks, lifestyle, health-related quality of life, symptoms, morbidity, and illness behavior. A continuum hypothesis was not supported, as the multiple logistic regression analysis showed no clear gradient in the different forms of suicidal tendency. Cohabitation status (single, p less than 0.0001), exposure to violent threats (p less than 0.0001), exposure to sexual abuse (p less than 0.0001), being a daily smoker (p less than 0.0001), doing nothing to stay healthy (p less than 0.0004), poor mental health (p less than 0.0001), mental symptoms within the past 2 weeks (p = 0.0003), contact with psychologist (p less than 0.0001), and absence from work due to illness (p = 0.005) were indicators significantly related to suicidal tendency.
