BackgroundHot flashes (HFs) affect up to 75% of menopausal women and pose a considerable health and financial burden. Evidence of acupuncture efficacy as an HF treatment is conflicting.ObjectiveTo assess the efficacy of Chinese medicine acupuncture against sham acupuncture for menopausal HFs.DesignStratified, blind (participants, outcome assessors, and investigators, but not treating acupuncturists), parallel, randomized, sham-controlled trial with equal allocation. (Australia New Zealand Clinical Trials Registry: ACTRN12611000393954).SettingCommunity in Australia.ParticipantsWomen older than 40 years in the late menopausal transition or postmenopause with at least 7 moderate HFs daily, meeting criteria for Chinese medicine diagnosis of kidney yin deficiency.Interventions10 treatments over 8 weeks of either standardized Chinese medicine needle acupuncture designed to treat kidney yin deficiency or noninsertive sham acupuncture.MeasurementsThe primary outcome was HF score at the end of treatment. Secondary outcomes included quality of life, anxiety, depression, and adverse events. Participants were assessed at 4 weeks, the end of treatment, and then 3 and 6 months after the end of treatment. Intention-to-treat analysis was conducted with linear mixed-effects models.Results327 women were randomly assigned to acupuncture (n = 163) or sham acupuncture (n = 164). At the end of treatment, 16% of participants in the acupuncture group and 13% in the sham group were lost to follow-up. Mean HF scores at the end of treatment were 15.36 in the acupuncture group and 15.04 in the sham group (mean difference, 0.33 [95% CI, -1.87 to 2.52]; P = 0.77). No serious adverse events were reported.LimitationParticipants were predominantly Caucasian and did not have breast cancer or surgical menopause.ConclusionChinese medicine acupuncture was not superior to noninsertive sham acupuncture for women with moderately severe menopausal HFs.Primary Funding SourceNational Health and Medical Research Council.
