Objective: To evaluate the risk of association between suicidal behaviors and comorbid anxiety disorders in adolescents with bipolar depression. Methods: We conducted a cross-sectional study using the nationwide inpatient sample (NIS) from the United States. This study included 9720 adolescent inpatients with bipolar depression and further grouped by co-diagnosis of anxiety disorders. Logistic regression analysis was used to evaluate the odds ratio (OR) of suicidal behaviors due to comorbid anxiety after controlling demographic confounders and psychiatric comorbidities. Results: Out of total inpatients, 34.8% (n = 3385) had comorbid anxiety disorders with a predominance in females (70.3%) and White patients (67.7%). About 54.1% of inpatients with comorbid anxiety had suicidal behaviors versus 44.6% in the non-anxiety cohort (p < 0.001). Comorbid anxiety disorders were associated with 1.35 times higher odds (95% CI 1.23–1.47, p < 0.001) for suicidal behaviors. Conclusion: Suicidal behaviors are significantly prevalent in bipolar depression adolescents with comorbid anxiety disorders. Anxiety disorders are an independent risk factor in bipolar depression that increase the risk of suicidal behaviors by 35%. This necessitates careful assessment and management of comorbid anxiety disorders in bipolar youth to mitigate suicidality.
