An estimated 17 percent of people living in Western
countries develop depression at some point in their
lives.
Previous research has suggested that exercise could
have an impact on depression,at least in the short
term.In a 2007 study of 202 depressed adults,
investigators found that those who went through
group-based exercise therapy did as well as those
treated with an antidepressant drug.That same
year,another small study found that regular
exercise improved depression symptoms in people
who've failed to get better with antidepressant
medication.
The current study,in contrast,looked at data
collected from only large studies,some of which
measured exercise's long-term impact by following
patients for months after the intervention
concluded.
The analysis,published in the Journal of Clinical
Psychiatry,is based on 13 studies including nearly 7
00 patients,half of whom were randomly assigned
an exercise intervention to help with their
depression.
On average,people appeared to have improved
slightly by the end of the exercise intervention,
relative to people who did not exercise.
However,according to the 5 studies that followed
patients for between 6 and 26 months,the benefits
of physical activity did not appear to last once the
program ended."If exercise was a pill,I do not
think the FDA (Food and Drug Administration) would
approve it as an antidepressant," he said.
Perhaps,Krogh suggested in an e-mail,exercise
itself has indirect effects on depression that only
last while people are doing it."Maybe the effect of
the intervention is not related to the physical
exercise but to an element of structure in the daily
lives of depressed patients," Krogh noted.Some of
the benefits,he noted,may include "meeting at
regular intervals with other patients and staff that
know the hassles of living with depression."
