RESUMO
OBJECTIVE: To evaluate the efficacy of electroacupuncture (EA) therapy on abdominal fat in obese women by using magnetic resonance imaging(MRI). METHODS: Thirty abdominal obesity women patients were randomly divided into control group (n=15) and EA group (n=15). The obesity patients of the control group did not receive any treatment for weight reduction, and those of the EA group were treated by EA stimulation of bilateral Neiting (ST 44), Fenglong (ST 40), Zusanli (ST 36), Huaroumen (ST 24), Tianshu (ST 25), Wailing (ST 26), Shuidao (ST 28), Fujie (SP 14), Daheng (SP 13), etc. for 25 min, once every other day, 3 times per week for 3 months. The patient's body weight, height, waist circumference (WC) were mea-sured with different devices, and the body mass index (BMI) was calculated, and the subcutaneous adipose tissue thickness at the inferior edges of L4, L5 and S3 and the superior edge of the pubic symphysis and the total abdominal fat volume between the L4 and S3 levels were detected using MRI systems before and after the treatment. RESULTS: The effects of the EA group were significantly superior to those of the control group in lowering difference values (between pre- and post-treatment) of BMI, WC and subcutaneous adipose tissue thickness at the levels of the inferior edges of L4, L5, S3 and the superior edge of the pubic symphysis(all P<0.01)and in reducing total abdominal fat volume between L4 and S3 (all P<0.01). After the treatment, the subcutaneous adipose tissue thickness at the superior edge of the pubic symphysis (P<0.01) and the total abdominal fat volume between L4 and S3 (P<0.05) were significantly decreased in the EA group compared to pre-treatment. There were no significant differences between post- and pre-treatment in BMI, WC, subcutaneous adipose tissue thickness at the levels of the L4, L5 and S3 in both EA and control groups and in the subcutaneous adipose tissue thickness at the level of the superior edge of the pubic symphysis and the total abdominal fat volume between L4 and S3 in the control group (P>0.05). CONCLUSIONS: EA intervention can effectively reduce abdominal fat in obese women based on the evaluation of MRI.
