Association of Suicidal Ideation With Physical Health Conditions, Mental Health Conditions, and Multimorbidity and the Modifying Role of Emotional Social Support: A Cross-Sectional Study in Japan.

Suicidal ideation is positively associated with the presence of only mental health conditions and multimorbidity, but emotional social support modifies only the association between suicidal ideation and the presence of only mental health conditions. These results suggest that it may be important to identify the type of social support one needs based on one's health condition to prevent suicide.
