Abstract: Objective　To investigatethe effect of fear of falling（FOF） on stride time variability（STV） in elderly patients with type 2 diabetes.Methods　A total of 204 elderly patients with type 2 diabetes were enrolled from the Department of Endocrinology of the Third Affiliated Hospital of Anhui Medical University between July and December 2016.The STV was compared amongpatients of different gender，age，education level，living status，monthly income，fall history，and FOF.The correlation between STV at a normal walking speed and MMSE score，pace speed，and step length in elderly patients with type 2 diabetes was analyzed using the Spearman rank correlation.Multivariate linear regression was used to analyze the factors which influence STV in the patients.Results　There was no significant difference in the STV among patients of different gender，age，education level，living status，monthly income level，and fall history（P>0.05）．There were 104 patients（51.0%） with a FOF；the STV in patients with a FOF was significantly different from the STV in patients without a FOF（P<0.05）．Spearman rank correlation analysis showed that the STV in patients was negatively correlated with pace speed and step length（rs=-0.333， -0.253；P<0.001），and was not correlated with MMSE score（rs=-0.097，P>0.05）．Multivariate linear regression analysis showed that pace and a FOF influenced the STV in elderly patients with type 2 diabetes（P<0.05）．Conclusion　Elderly patients with type 2 diabetes are more likely to have a FOF.A FOF and slow pace speedwere shown to influence the STV in these patients.
