Association Between Depression and Polypharmacy in Older Adults-A Systematic Review and Meta-Analysis.

ABSTRACT:

Background

Depression and polypharmacy are both common among older adults and may be closely interrelated.

Methods

This systematic review and meta-analysis examined the association between depression and polypharmacy by searching EMBASE, PubMed, Web of Science, and PsycINFO from inception to 18 May 2023. The review was registered in PROSPERO (CRD42022343619).

Results

Pooled analysis using a random-effects model demonstrated a strong association between depression and polypharmacy (OR = 2.49; 95% CI: 1.88-3.29; I² = 83%). Subgroup analyses revealed consistently elevated associations in both community-based and institutional/clinic-based populations.
