Exercise and antidepressant studies report lower depressive symptom scores in older adults
This brief uses only the meta-analysis abstract, which reports reduced symptoms with both approaches but leaves their comparison structure unclear.
Based on the published abstract. The full paper may contain additional methods, results and limitations.
The 30-second takeaway
Across included studies, physical activity and antidepressant medicines were each associated with lower depressive symptom scores in older adults. The pooled standardized effect was larger for physical activity, but the abstract does not establish a direct randomized comparison. These findings cannot determine whether exercise would outperform medication for an individual.
The abstract omits study designs, reference conditions and treatment durations. Those omissions limit interpretation of the reported difference between exercise and medication effects.
What researchers found
Depressive symptoms with physical activity
Standardized mean difference against an unspecified reference condition; assessment timing unreported. Negative indicates lower symptom scores.
Depressive symptoms with antidepressant medicines
Standardized mean difference against an unspecified reference condition; assessment timing unreported. Negative indicates lower symptom scores.
Reading the standardized differences
Both estimates use standard-deviation units, based on how widely symptom scores vary. Negative values indicate lower depressive symptoms; they are not raw questionnaire points or percentage improvements.
What the comparison establishes
The authors compared effects pooled across intervention categories and reported a statistically significant difference. Without clear comparison conditions or direct randomization details, that contrast does not establish which option is clinically superior.
