A study of 361 adults with depression published online in the British Medical Journal today finds no evidence that facilitated physical activity improved depression outcome or reduced use of antidepressants compared with treatment-as-usual (antidepressants without exercise) at four-, eight-, and 12-month follow-ups.
Note from Kermit Cole, “In the News” editor:
The study does not compare the effect of exercise on people not taking antidepressants to people taking them. Further, the study is investigating the effect of a relatively mild exercise intervention, as this Scientific American article points out.
Mad in America hosts blogs by a diverse group of writers. These posts are designed to serve as a public forum for a discussion—broadly speaking—of psychiatry and its treatments. The opinions expressed are the writers’ own.
I’m not seeing any data on the effectiveness of the antidepressants in either study arm; some patients in both groups were on antidepressants and some not.
The distinction between the groups is “the intervention group were also offered assistance from a physical activity facilitator.”
Could some patients in each have responded to antidepressants and others didn’t?
The data are not published with this study.
