To investigate socioeconomic variations in diabetes prevalence, uptake of screening for diabetic retinopathy, and prevalence of diabetic retinopathy.
The County of Gloucestershire formed the setting of the study. A cross-sectional study of people with diabetes was done on a countywide retinopathy-screening database. Diabetes prevalence with odds ratios, uptake of screening, prevalence of any retinopathy and prevalence of sight-threatening retinopathy at screening were compared for different area deprivation quintiles. Logistic regression was used to adjust for confounding.
With each increasing quintile of deprivation, diabetes prevalence increased (odds ratio 0.84), the probability of having been screened for diabetic retinopathy decreased (odds ratio 1.11), and the prevalence of sight-threatening diabetic retinopathy among screened patients increased (odds ratio of 0.98), while the prevalence of non-sight-threatening diabetic retinopathy remained unchanged with each increasing quintile of deprivation.
Sight-threatening diabetic retinopathy was associated with socioeconomic deprivation, but non-sight-threatening diabetic retinopathy was not. Uptake of screening was inversely related to socioeconomic deprivation.
调查糖尿病患病率、糖尿病视网膜病变筛查的接受情况以及糖尿病视网膜病变患病率的社会经济差异。
以格洛斯特郡为研究背景。基于全县视网膜病变筛查数据库，对糖尿病患者进行了一项横断面研究。比较了不同区域贫困五分位数组的糖尿病患病率（及比值比）、筛查接受情况、任何视网膜病变的患病率以及筛查时威胁视力的视网膜病变的患病率。采用逻辑回归分析来校正混杂因素。
随着贫困程度每增加一个五分位数组，糖尿病患病率上升（比值比为0.84），接受糖尿病视网膜病变筛查的概率下降（比值比为1.11），筛查患者中威胁视力的糖尿病视网膜病变患病率上升（比值比为0.98），而随着贫困程度每增加一个五分位数组，非威胁视力的糖尿病视网膜病变患病率保持不变。
威胁视力的糖尿病视网膜病变与社会经济贫困相关，而非威胁视力的糖尿病视网膜病变则不然。筛查接受情况与社会经济贫困呈负相关。
