Key Finding

This study protocol will evaluate whether manual acupuncture combined with lifestyle guidance is more effective than sham acupuncture for reducing BMI in postpartum obese women over an 8-week treatment period.

What This Means For You

This study examines whether acupuncture can help women lose weight after giving birth. Many women retain extra weight following pregnancy—typically around 4 kg at six months and nearly 3 kg even 18 months after delivery. This excess weight can affect both physical and mental health. Researchers in China designed a study to test if manual acupuncture is effective for postpartum weight loss compared to sham (fake) acupuncture.

The study will include 82 women with postpartum obesity, randomly divided into two groups. One group receives real acupuncture treatment while the other receives sham acupuncture that mimics the experience without actual needle insertion. Both groups also receive diet and exercise guidance. Treatment consists of 30-minute sessions three times weekly for eight weeks, with follow-up assessments at 14 and 20 weeks.

Researchers will primarily measure changes in body mass index (BMI) after the eight-week treatment period. They'll also track waist circumference, waist-to-hip ratio, blood sugar, cholesterol levels, thyroid function, and mental health indicators like depression and anxiety. The study carefully monitors safety throughout.

It's important to note this is a study protocol, meaning results aren't yet available. The research is designed to provide scientific evidence about whether acupuncture truly helps with postpartum weight loss beyond placebo effects. If results prove positive, acupuncture could offer a safe, non-pharmaceutical option for new mothers struggling with weight retention after pregnancy. If you're considering acupuncture for postpartum weight management, seek treatment from a licensed acupuncturist certified by your state or national regulatory board.

Clinical Notes for Practitioners

This multicenter, randomized, single-blind controlled trial protocol evaluates manual acupuncture (MA) efficacy for postpartum obesity versus sham acupuncture (SA). The study will randomize 82 postpartum obese women 1:1 to MA (n=41) or SA (n=41), with both groups receiving concurrent diet and exercise counseling. The intervention consists of 30-minute sessions three times weekly for eight weeks, with follow-up at 14 and 20 weeks post-treatment.

The primary outcome measures BMI change from baseline to week 8. Secondary outcomes include BMI changes at 4 weeks, waist circumference, waist-to-hip ratio, serological markers (glucose, lipids, thyroid function), compliance scales, and depression/anxiety assessments. Safety monitoring continues throughout.

Clinical significance: This protocol addresses the substantial issue of postpartum weight retention (averaging 2.9-4 kg at 12-18 months postpartum) using a rigorous sham-controlled design. The inclusion of metabolic markers and psychological assessments provides comprehensive evaluation of acupuncture's systemic effects. Results will offer evidence-based guidance for incorporating acupuncture into postpartum weight management protocols. Study registered ChiCTR2300067658.
