Abstract: Background　Evidence shows that more than 62% of low-violence fractures are caused by falls.Patients with osteoporosis（OP） have a higher risk of falls，so strengthening the prevention of falls in them is of great significance.However，there are many studies on in-hospital falls prevention，but few studies on out-of-hospital falls prevention.Objective　To evaluate the effectiveness of community-based fall prevention strategies in elderly patients with primary OP.Methods　100 elderly patients with primary OP were selected from Lujiazui Community Health Center from June to December 2016.By use of a random number table，they were evenly divided into the control group and intervention group，receiving 1-year routine outpatient follow-up visits，1-year routine outpatient follow-up visits and comprehensive interventions with community-based fall prevention strategies，respectively.Before and after the intervention，perceptions of OP were assessed by the Osteoporosis Knowledge Test（OKT），balance function was measured by the Berg Balance Scale（BBS），and lower extremity muscle strength was measured by the Motricity Index（MI-L），respectively.The incidence rate of falls during the intervention was counted and compared.Results　Compared with the baseline levels，mean OKT score，BBS score and MI-L score increased significantly in both groups after intervention（P<0.05）．Mean OKT score，BBS score and MI-L score were similar in both groups at baseline（P>0.05），but they increased more significantly in the intervention group after intervention（P<0.05）．There were no significant differences in the incidence rates of falls between the two groups during 1-3 months，4-6 months，and 7-9 months of intervention（P>0.05）．During the 10-12 months of intervention，the incidence rate of falls in the intervention group was lower than that of the control group（P<0.05）．Conclusion　Comprehensive interventions with community-based fall prevention strategies may improve their understanding level of OP，enhance the balance function and lower limb muscle strength，and effectively reduce the incidence of falls in elderly people with primary OP.So the interventions are worth promoting.
