"Depression during pregnancy is an issue of concern because it has negative
effects on both the mother and the baby as well as the rest of the family," said
Dr. Schnyer, one of the study's authors.
About 10% of pregnant women meet criteria for major depression and almost 20%
have increased symptoms of depression during pregnancy. The rates of depression
in pregnant women are comparable to rates seen among similarly aged non-pregnant
women and among women during the postpartum period, but there are far fewer
treatment studies of depression during pregnancy than during the postpartum
period.
Dealing with depression is difficult for pregnant women because the use of
anti-depressants poses concerns to the developing fetus and women are reluctant
to take medications during pregnancy.
In the study, an evaluator-blinded randomized trial, 150 participants who met
the Diagnostic & Statistical Manual of Mental Disorders, 4th edition
(DSM-IV) criteria for Major Depressive Disorder were randomized to receive
either acupuncture specific for depression (SPEC, n=52) or one of two active
controls: control acupuncture (CTRL, n=49) or massage (MSSG, n=49). Treatments
lasted eight weeks (12 sessions). Junior acupuncturists masked to treatment
assignment needled participants at points prescribed by senior acupuncturists.
Massage therapists and patients were not blinded. The primary outcome was the
Hamilton Rating Scale for Depression, administered by blinded raters at baseline
and after four and eight weeks of treatment. Data were analyzed using mixed
effects models and by intent-to-treat.
The results showed that the women who received SPEC experienced a
significantly greater decrease in depression severity (p<0.05) compared to
the combined controls (d=0.39, 95% CI [-1.31, 1.65]) or CTRL acupuncture alone
(p<0.05; Cohen´s-d = 0.46, 95% CI [-1.24, 2.31]). They also had a higher
response rate (63.0%) than the combined controls (44.3%; p<.05; NNT=5.3, 95%
CI [2.8, 75.0]) or CTRL acupuncture alone (37.5%; p<0.05; NNT=3.9, 95% CI
[2.2, 19.8]). Symptom reduction and response rates did not differ significantly
between controls (CTRL 37.5% and MSSG 50.0%). Mild and transient side effects
were reported by 43/150 participants (4 in MSSG; 19 in CTRL, 20 in SPEC).
Significantly fewer participants reported side-effects in MSSG than the two
acupuncture groups (p<0.01).
"The results of our study show that the acupuncture protocol we tested could
be a viable treatment option for depression during pregnancy" said Dr.
Schnyer.
