Acupoint Stimulation on Weight Reduction for Obesity: A Randomized Sham-Controlled Study.

Area of Science:

• Integrative and Complementary Medicine
• Obesity Research
• Acupuncture and Acupressure Studies

Background:

• Auricular acupoint stimulation is a popular weight loss method.
• The efficacy of auricular acupoint stimulation for obesity treatment requires further investigation.
• Obesity remains a significant global health concern necessitating effective interventions.

Purpose of the Study:

• To investigate the effect of auricular electrical stimulation combined with auricular acupressure on weight reduction in obese outpatients.
• To evaluate the efficacy of true acupoint stimulation versus sham acupoint stimulation over a 10-week period.
• To assess changes in body mass index and metabolic markers.

Main Methods:

• Single-blind randomized sham-controlled study involving 134 obese outpatients.
• Participants were assigned to either true auricular acupoint stimulation or sham acupoint stimulation.
• All participants received weekly nutrition counseling.

Main Results:

• Significant within-group changes were observed in body mass index, blood pressure, total cholesterol, triglyceride, and leptin or adiponectin levels over time.
• No significant between-group differences were found between the true acupoint stimulation and sham groups.
• The study could not rule out placebo effects or the impact of dietary consultation.

Conclusions:

• The study did not demonstrate a significant effect of auricular electrical stimulation combined with auricular acupressure on weight reduction compared to sham treatment in obese outpatients.
• The observed within-group improvements may be attributed to placebo effects or concurrent dietary interventions.
• Further research, including a no-treatment control group, is recommended to definitively establish the efficacy of auricular acupressure for weight management.
