Purpose: The purpose of this study was to examine the effects of auricular acupressure on reducing obesity in adult women withabdominal obesity. Methods: The study design was a non-equivalent control group pretest-posttest design. Participants were 58women, aged 20 years or older, assigned to the experimental group (n=30) or control group (n=28). Auricular acupressure usingvaccaria seeds was administered to the experimental group. The sessions continued for 8 weeks. Outcome measures included bodyweight, abdominal circumference, and body mass index, body fat mass, body fat percentage, triglyceride, total cholesterol, lowdensity lipoprotein cholesterol, high density lipoprotein cholesterol, and serum glucose. Results: Women in the experimental groupshowed significant decreases in body weight (t=6.19, p qqqlt;.001), abdominal circumference (t=4.01, p qqqlt;.001), and body mass index(t=2.58, p =.006) after 8 weeks compared with those in the control group. Conclusion: Results show that auricular acupressure usingvaccaria seeds was effective in decreasing body weight, abdominal circumference, body mass index, and triglyceride levels inadult women with abdominal obesity.
