ABSTRACT
Objective:To analyze the status and influencing factors of awareness of diabetic retinopathy (DR) knowledge in diabetics in Funing County, Jiangsu Province.Methods:This is a cross-sectional study. In 2021, a total of 2 125 residents with diabetes in Funing County, Jiangsu Province were recruited using cluster random sampling methods. General examinations were performed and ophthalmological evaluation were conducted including visual acuity in daily life, slit lamp microscope with preset lens, digital non-mydriatic fundus photography. Clinical assessment and classification of DR were according to the international standard clinical classifications of diabetic retinopathy in 2019. DR was classified into no obvious DR, mild non-proliferative diabetic retinopathy (NPDR), moderate NPDR, severe NPDR and proliferative diabetic retinopathy (PDR). Field questionnaire surveys were conducted to show the awareness rate of DR knowledge. Then Chi-square test and Logistic regression analysis were used to investigate influencing factors.Results:Among 2 125 subjects, 762 (35.86%, 762/2 125) residents were male and 1 363 (64.14%, 1 363/2 125) residents were female. A total of 444 (20.89%, 444/2 125) subjects were diagnosed as DR. Among which, 438 (20.61%, 438/2 125) subjects were NPDR, 6 (0.28%, 6/2 125) subjects were PDR. A total of 419 (19.72%, 419/2 125) subjects were diagnosed as cataract. The topic awareness rates were all below 45.00%. The overall population awareness rate was 19.45% (4 959/25 500). Awareness rate was correlated with age, visual acuity in daily life, education level, family history of diabetes, diabetic retinopathy grades and the type of treatment for diabetes ( P<0.001). Logistic regression analysis showed that the knowledge rate of prevention and treatment of DR Decreased significantly in patients aged 60-79 compared with those aged under 50 ( P<0.05). Compared with those with visual acuity <0.1 in daily life, the knowledge rate of DR prevention and treatment in those with visual acuity ≥0.1 was significantly decreased ( P<0.05). While primary school to college education, with family history of diabetes, with DR, oral hypoglycemic agents and/or insulin treatment were associated with higher awareness rate ( P<0.05). Conclusions:The DR knowledge level is low among diabetics in Funing County, Jiangsu Province in 2021. Age, visual acuity in daily life, education level, family history of diabetes, with DR and receiving drug treatments are main influencing factors for diabetic’s awareness.
ABSTRACT
Objective:To investigate the prevalence and influencing factors of mild visual impairment in type 2 diabetic patients aged ≥50 years living in Funing County, Jiangsu Province.Methods:A population-based cross-sectional study was adopted.Cluster sampling was conducted among diabetic patients aged ≥50 years registered in the Chronic Disease Information Center of Funing County Center for Disease Prevention and Control from March 7th to April 20th, 2019.General information of selected patients was collected.Visual and ocular examinations on site were performed by ophthalmologists and technicians.The International Council of Ophthalmology standard for mild visual impairment, 0.3≤best corrected visual acuity<0.8 was adopted.The influencing factors of mild visual impairment were analyzed by logistic regression.This study protocol was approved by the Ethics Committee of Affiliated Hospital of Nantong University (No.2014-071).Results:Among the included 2 067 patients, 1 909 cases completed the investigation, with a response rate of 92.4%.There were 1 146 patients with mild visual impairment in at least one eye, and the prevalence of mild visual impairment was 60.00%.Among the eyes examined, 1 832 eyes were with mild visual impairment, accounting for 47.98%.Cataract (896/1 632), refractive error (515/1 632) and diabetic retinopathy (166/1 632) were the main causes of mild visual impairment in diabetic patients, accounting for 54.90%, 31.61% and 10.19%, respectively.Aging, female gender, low educational attainment, oral hypoglycemic drugs or subcutaneous insulin injection were risk factors for mild visual impairment in both eyes.Higher educational attainment, more sunshine exposure and exercise were protective factors for mild visual impairment in both eyes.Conclusions:The prevalence of mild visual impairment is relatively high in type 2 diabetic patients.Cataract surgery, correction of refractive error may help to improve mild visual impairment.Strengthening blood glucose control, more physical exercise and outdoor activities may slow the progression of mild visual impairment and prevent it from moderate and severe visual impairment.
