Abstract: ObjectiveTo evaluate the effectiveness of community-based interventions among type 2 diabetes mellitus.MethodsLiteratures regarding the effectiveness of combined community-based interventions among Type 2 diabetes in China since 2006 were collected through databases including Wanfang Med Online, VIP Chinese Science and Technology Periodical Databases, China National Knowledge Infrastructure (CNKI), Chinese Biomedical Literature Databases（CBM）, and PubMed Databases. Data were analyzed with Stata 12.0 software .ResultsA total of 22 articles were included in the study, containing 1 723 cases in the intervention group and 1 674 cases in the control group. The fasting blood-glucose（FBG） （SMD=0.726，95%CI: 0.359-1.092）, meal after 2 h blood glucose(P2hBG）（SMD=0.798，95%CI: 0.407-1.127）, glycated hemoglobin (HbAlc)（SMD=0.735，95%CI:0.251-1.219）,total cholesterol(TC)（SMD=0.476，95%CI: 0.098-0.855），triglyceride(TG) (SMD=0.721，95%CI: 0.227-1.214）in the community-based intervention group were lower than those in the control group (P<0.05 for all).ConclusionThe community-based interventions had significant effectiveness on control of type 2 diabetes. Active community-based interventions should be recommended for type 2 diabetes.
