Acupuncture for Insulin Resistance in Women With Polycystic Ovary Syndrome

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.
