Depression treatment
Depression linked to C. difficile infection risk
Open access · cc by · source: Europe PMC
Adults with major depression had higher CDI rates, and specific antidepressants plus living alone/widowhood also associated with infection risk.

Key findings
CDI rates were 282.9 vs 197.1 per 100,000 person-years with vs without depression; adjusted odds of CDI were 36% higher with major depression; widowhood and living alone also associated.
Methodology
Complementary analyses used linked Health and Retirement Study–Medicare data and clinical cohorts to relate depression diagnoses, antidepressants, and social factors to CDI.
Limitations
Whether treating depression lowers CDI, or that all antidepressants equally raise risk; residual confounding by healthcare exposure remains possible.
How this study connects
Role on claims
Each row is a claim on a concept or method page where this paper supports, challenges, or qualifies the statement. Roles are hand-checked — not a model guess.
Multiple studies in this library examine depression treatment with empirical patient or population outcomes rather than opinion alone.
Evidence for the claim as stated.
CDI rates were 282.9 vs 197.1 per 100,000 person-years with vs without depression; adjusted odds of CDI were 36% higher with major depression; widowhood and living alone also associated.
Evidence for the claim as stated.
Effect sizes and settings differ across depression treatment studies — digital vs clinic, trial vs observational — so results should not be pooled casually.
Evidence for the claim as stated.
Linked Health and Retirement Study–Medicare analyses found CDI rates of 282.9 versus 197.1 per 100,000 person-years with versus without depression, and adjusted odds of CDI 36% higher with major depression; widowhood and living alone were also associated. The model does not show that treating depression would lower CDI, and residual confounding by healthcare exposure remains possible.
Evidence for the claim as stated.
The same odds-ratio language is asked to do two different jobs. Senegal's AOR 3.10 and the CDI 36% excess odds are observational associations after covariate adjustment. Text4Heart's AOR 2.55 is a randomised contrast that itself was gone by 6 months. Reading every AOR as if it were that trial overclaims the survey papers and understates how fragile a trial AOR can be once follow-up continues.
