Abstract
The stress sensitization model indicates that early adversity (e.g., childhood stress) sensitizes individuals to subsequent proximal stress (e.g., stressful life events in adult life), thereby increasing their vulnerability to psychiatric disorders. However, the effect of stress sensitization on suicidality in patients with major depressive disorder (MDD) has not been previously investigated. Data for the present study were derived from the Objective Diagnostic Markers and Personalized Intervention in MDD Patients (ODMPIM) study. The psychiatric diagnosis and suicidal ideation were evaluated by the Mini‐International Neuropsychiatric Interview (M.I.N.I.). We used a multiple logistic analysis to examine the association among childhood adversity (CA), adulthood adversity (AA) and suicidal ideation. Among 1084 MDD patients, 48.6% had suicidal ideation and 65.6% experienced life adversity during their childhood or adulthood. Patients who reported suicidal ideation were more likely to report CA (46.7% vs. 38.7%, P = 0.008) or AA (49.5% vs. 40.9%, P = 0.004) than patients without suicidal ideation. Patients who experienced two waves of adversity (both CA and AA) were associated with higher rates of suicidal ideation (odds ratio = 1.68, 95% CI = 1.19–2.37, P = 0.003); however, neither CA nor AA alone was associated with suicidal ideation. This study first verifies the hypothesis of stress sensitization on suicidal ideation in patients with MDD. Focusing on stress sensitization may enhance the early identification of MDD patients at suicidal risk and the ability to provide timely and appropriate intervention.
