West J Nurs Res. 2015 Dec;37(12):1517-30. doi: 10.1177/0193945914548707. Epub 2014 Sep 1. Acupoint Stimulation on Weight Reduction for Obesity: A Randomized Sham-Controlled Study. The results showed significant differences in body mass index, blood pressure, total cholesterol, triglyceride, and leptin or adiponectin over time within the group, but not between the groups. This study could not exclude the effect of placebo and dietary consultation. Further study that adds a control group receiving no treatment is therefore needed to confirm the effects of auricular acupressure.
