Effect of electroacupuncture versus cognitive behavioral therapy for perimenopausal insomnia: a non-inferiority, randomized controlled trial.

If you're going through perimenopause and struggling to sleep, you're not alone. Perimenopausal insomnia affects millions of women and can seriously impact daily life, mood, and overall wellbeing. Researchers recently compared two non-drug treatments to see which works better: electroacupuncture (EA) and cognitive behavioral therapy for insomnia (CBT-I).

Electroacupuncture is a form of acupuncture where small electrical currents are passed between needles to enhance stimulation of specific points on the body. CBT-I is a structured talking therapy that helps people change thoughts and habits that interfere with sleep. Both are considered gold-standard, drug-free approaches to treating insomnia.

In this study, 160 perimenopausal women were randomly assigned to receive either electroacupuncture or CBT-I over eight weeks. Researchers measured sleep improvements using a standard questionnaire called the Insomnia Severity Index (ISI). The goal wasn't to prove one treatment was better, but to determine whether electroacupuncture was 'non-inferior' — meaning it worked well enough to be considered a genuine alternative.

The results were encouraging for acupuncture. Both groups experienced meaningful improvements in sleep quality. Women receiving electroacupuncture saw their insomnia scores drop by an average of 6.8 points, while those in the CBT-I group dropped by 9.2 points. Although CBT-I produced slightly larger improvements, electroacupuncture still fell within the pre-defined threshold to be considered non-inferior. No serious side effects were reported in either group.

What this means for you: if CBT-I isn't accessible, affordable, or simply not your preference, electroacupuncture is a clinically validated alternative worth considering for perimenopausal sleep problems.

This two-arm, non-inferiority RCT (n=160) evaluated electroacupuncture (EA) versus cognitive behavioral therapy for insomnia (CBT-I) in perimenopausal women with insomnia. Participants were randomized 1:1 (n=80 per arm), with a pre-specified non-inferiority margin of -4 points on the Insomnia Severity Index (ISI). The primary outcome was mean ISI change from baseline to week 8. At week 20 follow-up, retention was 95% (EA) and 89% (CBT-I). EA produced a mean ISI reduction of 6.80 points (95% CI: 5.84–7.77) versus 9.16 points (95% CI: 8.14–10.17) for CBT-I. The between-group difference of -2.36 points (95% CI: -3.77 to -0.94) remained within the non-inferiority margin. No serious adverse events were recorded. Clinically, EA represents a viable, evidence-supported alternative to CBT-I for perimenopausal insomnia, particularly where CBT-I access is limited or patient preference favors a somatic intervention.
