Acupuncture ameliorated vasomotor symptoms during menopausal transition: single-blind, placebo-controlled, randomized trial to test treatment efficacy.

OBJECTIVES

This study aimed to evaluate the effects of acupuncture on women with vasomotor symptoms during the menopausal transition with the aid of the Kupperman-Blatt Menopausal Index.

METHOD

Crossover, single-blind, sham-controlled trial with 100 women randomly divided into two groups of 50 participants each: G1 and G2. During the first 24 weeks of treatment, the G1 women received acupuncture and the G2 women were given sham acupuncture. The crossover was then applied: the G1 participants were given sham acupuncture, and the G2 participants received acupuncture for 24 more weeks.

RESULTS

The mean score of hot flashes of the group who first experienced acupuncture (G1) was statistically higher than that of the group that started with sham acupuncture (G2, P = 0.020). Also, both groups had similar mean scores in the middle of the study (both were receiving acupuncture). During the last 6 months of the study, after crossover, the values of G2 (acupuncture) were lower than those of G1 (sham acupuncture).

CONCLUSIONS

Acupuncture treatment may mitigate hot flashes and other climacteric symptoms during the menopausal transition.
