Acupuncture for symptoms in menopause transition: a randomized controlled trial

Area of Science:

• Integrative and Complementary Medicine
• Women's Health
• Reproductive Endocrinology

Background:

• Acupuncture is a traditional therapy used for menopausal symptoms, but robust evidence is limited.
• The menopause transition presents various symptoms impacting women's quality of life.
• Evaluating electroacupuncture's efficacy for these symptoms is crucial.

Purpose of the Study:

• To assess the effectiveness of electroacupuncture in alleviating menopause transition symptoms.
• To compare electroacupuncture with sham electroacupuncture in a randomized trial.
• To investigate the impact on quality of life and hormonal changes.

Main Methods:

• Prospective, multicenter, randomized, participant-blinded trial with 360 women.
• 8 weeks of electroacupuncture at traditional acupoints versus sham electroacupuncture at nonacupoints.
• Primary outcome: Menopause Rating Scale (MRS) total score change at week 8; secondary outcomes included hot flashes, quality of life, and hormone levels.

Main Results:

• Electroacupuncture did not achieve a clinically important difference in reducing MRS total scores compared to sham treatment at week 8 (1.8 difference vs. 5-point threshold).
• Significant improvements were observed in Menopause-Specific Quality of Life Questionnaire scores, exceeding the minimal clinically important difference.
• No significant differences in key female hormone levels were found between groups, except for FSH/LH ratios.

Conclusions:

• Eight weeks of electroacupuncture did not appear to relieve menopausal symptoms but did improve quality of life.
• The study's generalizability may be limited due to mild baseline menopausal symptoms in participants.
• Further research may be needed to explore electroacupuncture's role in managing specific aspects of menopause.
