ABSTRACT
Objective To study the prevalence and the related risk factors of diabetic peripheral neuropathy(DPN) after good blood glucose well controlled among in middle-aged and old-aged population with type 2 diabetes mellitus in a community of Beijing.Methods DPN was screened by Michigan neuropathy screening instrument (MNSI),and common blood biochemical parameters were tested,among over 45 years of age registered population patients with type 2 diabetes mellitus in Shuangjing community of Chaoyang District of Beijing.Results The blood glucose control rate was 90.36％ (253/280),and the prevalence of DPN was 25.36％ (71/280) with male of 24.47 ％ (23/94) and female of 25.81％ (48/186).Univariate analysis showed that both age and HbA1c in DPN group were higher than that of non-DPN group,and the differences were statistically significant(P =0.000,0.008).The level of plasma low density lipoprotein cholesterol(LDL-C) of the DPN group was lower than that of the non-DPN group,and the difference was statistically significant (P=0.017).The hypertension prevalence rate of the DPN group was 87.32％(62/71),higher than that of the nonDPN group(75.6％ (158/209)),and the difference was statistically significant (P =0.037).The multivariate logistic regression analysis showed that the estimate of parameter for age was 0.143 (P =0.0001),OR was 1.153,95％CI was from 1.029 to 1.219,for HbA1c was 0.529(P=0.03),OR was 1.698,95％CI was from 1.053 to 2.738,and for LDL-C was-O.919 (P =0.018),OR was 0.399,95％ CI was from 0.186 to 0.854.Conclusion The prevalence of DPN is still above 25％ among middle-aged and old-aged in a community,even though the well controlled rate of blood glucose control rate is above 90％.It is possible that old age and HbA1c are related to DPN,apart from blood glucose.
