Key result
Short-term β-blockers are linked to ~91% higher depression risk, suggesting protopathic bias among propranolol users.
Why the study?
Depression is a commonly cited adverse effect of beta-blockers, but evidence for a causal relationship is limited.
Does the use of beta-blockers increase the risk of new-onset depression in adults?
Case-Control (n=237,410)
Yes
Does the use of beta-blockers increase the risk of new-onset depression in adults?
Effect estimate: aOR 1.91 (95% CI 1.72-2.12)
The commonly cited association between beta-blockers and depression is likely due to protopathic bias (e.g., prescribing propranolol for neuropsychiatric symptoms) rather than a true causal relationship.
No takes yet. Share an insight, caveat, or question.
No need to avoid β-blockers over depression concerns; challenges causal interpretations from prior observational data.
Bornand et al. (2022) conducted a case-control in Incident depression (n=237,410). β-blockers vs. Never use of β-blockers was evaluated on Incident depression (current short-term use of any β-blocker) (aOR 1.91, 95% CI 1.72-2.12). Current short-term use of β-blockers was associated with an increased risk of depression (aOR 1.91), but this was mostly confined to propranolol users with neuropsychiatric disorders, suggesting protopathic bias rather than a causal link.
