People with depression may benefit as much from acupuncture as they do from counseling, suggests a new study.
Researchers found one in three patients was no longer depressed after three months of acupuncture or counseling, compared to one in five who received neither treatment.
"For people who have depression, who have tried various medical options, who are still not getting the benefit they want, they should try acupuncture or counseling as options that are now known to be clinically effective," said Hugh MacPherson, the study's lead author from the University of York in the UK.
Previous studies looking at whether acupuncture helps ease depression have been inconclusive. Those studies were also small and didn't compare acupuncture to other treatment options.
"What's more important for the patient is does it work in practice and that is the question we were asking," MacPherson said.
For their study, he and his colleagues recruited 755 people with moderate or severe depression. The researchers split participants into three groups: 302 were randomly assigned to receive 12 weekly acupuncture sessions, another 302 received weekly counseling sessions and 151 received usual care only.
About 70 percent of people had taken antidepressants in the three months before the study and about half reported taking pain medications. People did not have to stop taking their medicine to participate in the study.
At the outset, participants had an average depression score of 16 on a scale from 0 to 27, with higher scores symbolizing more severe depression. A 16 is considered moderately severe depression.
After three months, people assigned to the acupuncture group had an average score of about 9 - on the higher end of the mild depression category. Scores fell to 11 among members of the counseling group and about 13 in the usual care group, both considered moderate depression.
Participants who received acupuncture or counseling saw larger improvements over three months than those who had neither treatment. Those benefits remained for an additional three months after the treatments stopped.
However, any differences between acupuncture and counseling could have been due to chance, the researchers reported Tuesday in PLOS Medicine.
They found doctors would need to treat seven people
