One-year follow-up for patients with diabetic retinopathy in Shanghai communities / 中华全科医师杂志

ABSTRACT

Objective To investigate the outcomes of patients with diabetic retinopathy (DR) in Shanghai communities and the influencing factors.Methods From October 2015 to April 2016,533 type 2 diabetic patients with DR were selected by target sampling and cluster random sampling method from six community health service centers in Shanghai.Patients were followed up for 1 year.The demographic information,physical examination,laboratory tests and eye fundus exam results were documented and the DR was graded.The factors associated with the regression of DR were analyzed.Results Total 478 patients,including 280 females (58.6％) and 198 males (41.4％),were followed up for 1 year.The mean age of patients was (64±7) years and the mean disease duration was (8.85±4.20) years.The original DR lesion was remitted in 35 patients with an improvement rate of 7.3％;while the original DR lesion was aggravated in 29 patients with a progression rate of 6.1％.Ordinal logistic regression analysis revealed that age (OR=0.197,95％CI:0.056-0.699),body mass index (BMI) (OR=0.383,95％CI:0.171-0.856),glycosylated hemoglobin (HbAlc) (OR=0.287,95％CI:0.102-0.803),triglycerides (TG) (OR=0.541,95％CI:0.295-0.991),urinary albumin to creatinine ratio (ACR)(OR=0.218,95％CI:0.066-0.720) were associated with DR in type 2 diabetic patients.Conclusion The regression of DR is closely related to age,BMI,glucose,serum lipids and renal function,so it is suggested that lowering BMI,controlling glucose and serum lipids and maintaining normal kidney function are necessary for preventing the progression and promoting the improvement of DR in diabetic patients.
