不同电流强度和留针时间电针对中心性肥胖患者腰围、腰臀比的影响

目的]观察不同电针电流强度和留针时间对中心性肥胖患者腰围、腰臀比的影响。方法]将96例中心性肥胖患者随机分为1mA 30min组、1mA 60min组、2mA 30min组、2mA 60min组4组,分别运用相应刺激参数的电针治疗3个疗程,观察各组患者治疗前及治疗结束后的腰围、腰臀比。结果]4组患者治疗后腰围、腰臀比均较治疗前减小（均P〈0.01）,腰围变化率、腰臀比变化率均与电针留针时间有关（均P〈0.01）,1mA 60min组腰围、腰臀比减小程度均大于1mA 30min组（P〈0.01）,2mA 60min组腰围、腰臀比减小程度均大于2mA 30min组（均P〈0.01）。腰围变化率、腰臀比变化率均与电针电流强度无关,1mA 30min组和2mA 30min组以及1mA 60min组和2mA 60min组腰围变化率、腰臀比变化率比较差异均无显著性意义（均P〉0.05）。结论]电针对中心性肥胖患者腰围、腰臀比的影响程度与其留针时间长短有关,长时间（60min）留针者对中心性肥胖患者腰围、腰臀比的减小程度大于短时间（30min）留针者。

Influence of Electric-acupuncture with Different Current Intensity and Needles Retaining Time on Waist Circle and Waist to Hip Ratio of Patients with Center Obesity

Objective] To observe the influence of current intensity and needles retaining time of EA（electric-acupuncture） on waist circle and waist to hip ratio of patients with center obesity.Method] 96 patients with center obesity were randomly divided into 4 groups such as 1mA 30min group,1mA 60min group,2mA 30min group and 2mA 60min group.Then they were treated with respective stimulation parameters of EA.We observed all patients ＇waist circle and waist to hip ratio before the beginning and after the finishment of treatment.Result] Waist circle and waist to hip ratio of 4 groups of posttreatment were all smaller than those of pre-treatment.The change ratio of waist circle and waist to hip ratio bore a relation to needles retaining time of EA.The waist circle and waist to hip ratio of the 1mA 60min group decreased more than the 1mA 30min group did,and those of the 2mA 60min group decreased more than the 2mA 30min group did.The change ratio of waist circle and waist to hip ratio did not bear a relation to current intensity of EA.The waist circle and waist to hip ratio of the 1mA 30min group and the 2mA 30min group had no differentiation.Those of the 1mA 60min group and the 2mA 60min group also had no differentiation.Conclusion] The changes of the waist circle and waist to hip ratio of the patients with center obesity bear a relation to the needles retaining time of EA.Retaining long time（60 minutes） of EA will help lower more waist circle and waist to hip ratio than retaining short time（30 minutes） do.
