Objectives:To investigate the effects of electroacupuncture on parameters related to obesity in adults with abdominal obesity.
Methods: A three arm randomized single blind pilot study was conducted from Jan 4 to March 25, 2010 in Kyung Hee Oriental Medical Hospital. The subjects were 39 adults with abdominal obesity and were randomly divided by computer generated random table into 3 groups; EA(electroacupuncture), sham EA(sham electroacupuncture) and waitlist groups. Acupuncture points located at abdomen(CV12, CV6, ST25, SP15, SP14) and extremities(LI4, LI11, ST36, ST44) were inserted by disposable stainless steel needles and were stimulated 30 minutes with 24Hz, 0.27∼1.3mA(tolerable strength), asymmetric biphasic continuous pulse wave form by STN-111 Stratek device in EA group. Two treatment sessions per week for 5 weeks(10 sessions in total) were done in EA and sham EA groups. The primary outcome measurement was WC(waist circumference), and the secondary outcome measure- ments included WHR(waist hip ratio), ASF(thickness of abdominal subcutaneous fat), and inbody measurements of BW(body weight), BMI(body mass index), BFR(body fat ratio) and VFA(visceral fat area), and also scores of BULIT-R(bulimia test revised), KoQoL(Korean obesity of QoL) and BSQ(body shape questionnaire).
Results: All of 39 subjects were included in ITT(intention-to-treat) analysis. There were significant reductions in WC, WHR and ASF after 5-week electroacupuncture treatments and the percentage reductions were significantly greater than sham EA or waitlist group. There were no significant differences between groups in percentage reductions of other parameters(BW, BMI, BFR, VFA, BULIT-R, KoQoL and BSQ). But, there were continuous reductions in BW, BMI, BFR and VFA at 3 weeks after the end of treatment and there was significant reduction in BW compared with the baseline value in EA group. No seriously adverse effects were reported during the period.
Conclusions: Electroacupuncture was more effective than sham electroacupuncture or no intervention on the reduction of WC, WHR and ASF in adults with abdominal obesity.
