Acupuncture for Insulin Resistance in Women With Polycystic Ovary Syndrome
Sponsor: Peking University Third Hospital
Summary
This two-stage clinical research programme aims to evaluate the preliminary effectiveness and safety of acupuncture for improving insulin resistance in women with polycystic ovary syndrome (PCOS). Phase I will be a prospective, single-centre, open-label, single-arm exploratory trial involving 20 participants, all of whom will receive active acupuncture plus lifestyle management. Acupuncture will be administered three times per week for 12 weeks, followed by a 12-week follow-up period. The study will primarily assess safety, tolerability, feasibility, and the preliminary change in the homeostatic model assessment of insulin resistance (HOMA-IR) from baseline to Week 12. The effect size and variability of HOMA-IR change, together with safety, adherence, and dropout data obtained from Phase I, will be used to determine the sample size and finalize the design of Phase II. Phase II is planned as a prospective, multicentre, parallel, randomized, participant- and outcome assessor-blinded, sham-controlled trial comparing active acupuncture plus lifestyle management with sham acupuncture plus lifestyle management to confirm the effectiveness and safety of the intervention.

Interventions
Active Acupuncture
Active acupuncture is administered for 30 minutes, three times per week for 12 consecutive weeks (up to 36 sessions). Two standardized sets of acupuncture points are alternated. Sterile needles are inserted 15-40 mm and manually stimulated to elicit de qi. Selected points receive 2-Hz electroacupuncture (0.3-ms pulse width; approximately 0.1-2.0 mA at a comfortable intensity), while needles not connected to the stimulator are manually stimulated every 10 minutes.
Sham Acupuncture
Sham acupuncture is administered for 30 minutes, three times per week for 12 consecutive weeks (up to 36 sessions). Sterile 0.20 × 20 mm needles are inserted superficially (\<5 mm) at non-acupuncture and non-meridian points on the shoulder and upper arm, without manual stimulation. Electrodes are attached and the stimulator is set to zero intensity to mimic active electroacupuncture.
Lifestyle Management
All participants receive individualized lifestyle management beginning at baseline. The program combines face-to-face nutritional consultation with a web- and mobile-based PCOS management platform and wearable step counter. Participants receive individualized dietary and physical activity advice, daily exercise and diet prescriptions, weekly review of weight-loss goals and food diaries, and regular feedback from the research team.
