AIM: To investigate the prevalence rate and risk factors of diabetic retinopathy(DR)in type 2 diabetes mellitus(T2DM)in Fengyutan community in Shenyang.

METHODS: Totally 457 community residents with T2DM were selected in 2011. Ninety-two of these people accepted the reexamination in 2013. Besides, there were 312 residents with T2DM joined in the study in the same year. Basic condition and life style were investigated, and diabetic retinopathy screening were performed. Logistic multiple regression was used to analyze related risk factors.

RESULTS: The prevalence of DR were 15.8% and 41.2% in 2011 and 2013 respectively in the community. Compared with NDR group, age, family history of DM, duration of DM, fasting blood-glucose(FBG), 2h post-meal blood glucose(2hPG), hemoglobin A1c(HbA1c), total cholesterol(TC), serum creatinine(Scr), systolic blood pressure(SBP), high- and low-density lipoprotein cholesterol(HDL-C, LDL-C)were statistically significant(P<0.05). The result of logistic regression showed that age, duration of DM, HbA1c, SBP and HDL-C were independent risk factors of DR. There were 31 new sufferers in 92 reexamined patients(33.7%)in 2013 and the main aetiological agent was poor glycemic control.

CONCLUSION: The prevalence of DR in Fengyutan community was much higher than the other studies in northern China. It was primarily concerned with long duration of DM, poor glycemic control, inadequate concern with or even neglect of DM and the related oculopathy, hypertension and hyperlipidemia and so on.
