This research is planned to build a basis about the effect of acupuncture on serum metabolic parameters in pre-menopausal obese women with economic evaluation.

It is consisted with two sub research.

First, clinical research to assess the effect of acupuncture for obesity on serum metabolic parameters will be processed with randomized, patient-assessor blinding, and sham-acupuncture controlled study design. 120 subjects would be collected and divided into two groups(experimental and placebo, 60 subjects each). Experimental group will undergo with real acupuncture treatment(manual acupuncture + electroacupuncture) twice a week, for 6 weeks. The effect on serum metabolic parameters will be assessed at 0 and 6 weeks.

Second is qualitative research to make a basis through the evaluation of economic efficacy and patients' satisfaction with acupuncture treatment for obesity.
