To objectively evaluate the effectiveness of Baduanjin,the health qigong,on the physiological functions of and blood lipid in the middle aged and elderly people,databases such as PubMed,Web of Science,EMbase,CBM,CNKI were electronically searched to collect the randomized controlled trials (RCT) published from January 2000 to December 2013.Meta-analyses were performed by using RevMan 5.2 soft ware.The results showed that the Baduanjin group was superior to the control group in decreases of systolic pressure （MD=－6.87，95%CI（－9.15，－4.60），P<0.000 01） and diastolic pressure （MD=－4.07，95%CI（－5.94，－2.19），P<0.000 1）,increase of vital capacity （MD=393.15，95%CI（102.62，683.68），P=0.008），decrease of serum TC （MD=－0.60，95%CI（－1.07，－0.12），P=0.01）,serum TG （MD=－0.23，95%CI（－0.32，－0.14），P<0.000 01） and serum LDL-C （MD=－0.31，95%CI（－0.57，－0.05），P=0.02）,and increase of serum HDL-C （MD=0.19，95%CI（0.06，0.32），P=0.003）;and there were statistical differences.It can be concluded that the effects of Baduanjin can improve the physiological functions of the middle aged and elderly people and control their blood lipid level;and thus it can be used as the means for prevention and treatment of hypertension,hyperlipidemia and other age-related diseases.
