To provide estimates of visual impairment in people with diabetes attending screening in a multi-ethnic population in England (United Kingdom).
The Diabetic Retinopathy In Various Ethnic groups in UK (DRIVE UK) Study is a cross-sectional study on the ethnic variations of the prevalence of DR and visual impairment in two multi-racial cohorts in the UK. People on the diabetes register in West Yorkshire and South East London who were screened, treated or monitored between April 2008 to July 2009 (London) or August 2009 (West Yorkshire) were included in the study. Data on age, gender, ethnic group, visual acuity and diabetic retinopathy were collected. Ethnic group was defined according to the 2011 census classification. The two main ethnic minority groups represented here are Blacks ("Black/African/Caribbean/Black British") and South Asians ("Asians originating from the Indian subcontinent"). We examined the prevalence of visual impairment in the better eye using three cut-off points (a) loss of vision sufficient for driving (approximately <6/9) (b) visual impairment (<6/12) and (c) severe visual impairment (<6/60), standardising the prevalence of visual impairment in the minority ethnic groups to the age-structure of the white population.
Data on visual acuity and were available on 50,331 individuals 3.4% of people diagnosed with diabetes and attending screening were visually impaired (95% confidence intervals (CI) 3.2% to 3.5%) and 0.39% severely visually impaired (0.33% to 0.44%). Blacks and South Asians had a higher prevalence of visual impairment (directly age standardised prevalence 4.6%, 95% CI 4.0% to 5.1% and 6.9%, 95% CI 5.8% to 8.0% respectively) compared to white people (3.3%, 95% CI 3.1% to 3.5%). Visual loss was also more prevalent with increasing age, type 1 diabetes and in people living in Yorkshire.
Visual impairment remains an important public health problem in people with diabetes, and is more prevalent in the minority ethnic groups in the UK.
提供在英国（联合王国）的多民族人群中接受筛查的糖尿病患者的视力障碍估计值。
在英国不同种族人群中的糖尿病视网膜病变（DRIVE UK）研究是一项关于 DR 和视觉障碍在英国两个多种族队列中的种族差异的横断面研究。2008 年 4 月至 2009 年 7 月（伦敦）或 2009 年 8 月（西约克郡）期间在西约克郡和伦敦东南部的糖尿病登记处接受筛查、治疗或监测的人群被纳入研究。收集了年龄、性别、种族、视力和糖尿病视网膜病变的数据。种族群体根据 2011 年人口普查的分类来定义。这里主要的两个少数民族群体是黑人（“黑人/非洲/加勒比/英国黑人”）和南亚人（“来自印度次大陆的亚洲人”）。我们使用三个截止点（a）足以导致驾驶困难的视力丧失（约<6/9）（b）视力障碍（<6/12）和（c）严重视力障碍（<6/60）来检查优势眼的视力障碍患病率，并将少数民族群体的视力障碍患病率标准化为白人人口的年龄结构。
50331 人（约占诊断为糖尿病且接受筛查的人群的 3.4%）有视力和数据，其中 3.4%（95%置信区间（CI）3.2%至 3.5%）视力障碍，0.39%（0.33%至 0.44%）严重视力障碍。黑人（4.6%，95%CI 4.0%至 5.1%）和南亚人（6.9%，95%CI 5.8%至 8.0%）的视力障碍患病率高于白人（3.3%，95%CI 3.1%至 3.5%）。随着年龄的增长、1 型糖尿病和居住在约克郡的人群，视力损失也更为普遍。
视力障碍仍然是糖尿病患者的一个重要公共卫生问题，在英国的少数民族群体中更为普遍。
